Caract\u00e9ristiques de fonctionnement<\/strong> de robinet \u00e0 soupape<\/h2>\n\n\n\nLa forme d'\u00e9tanch\u00e9it\u00e9 du robinet \u00e0 soupape est une \u00e9tanch\u00e9it\u00e9 forc\u00e9e. Lorsque la vanne est ferm\u00e9e, une force suffisante doit \u00eatre appliqu\u00e9e sur le disque de la vanne pour obtenir l'effet d'\u00e9tanch\u00e9it\u00e9, et l'\u00e9tanch\u00e9it\u00e9 ne peut \u00eatre r\u00e9alis\u00e9e que lorsque la pression sp\u00e9cifique est suffisante.<\/p>\n\n\n\n
La force d'\u00e9tanch\u00e9it\u00e9 et la pression moyenne sont sur le m\u00eame axe. Lorsque le fluide entre par la partie inf\u00e9rieure du disque de la vanne (entr\u00e9e basse et sortie haute), le couple de fermeture de la vanne est sup\u00e9rieur au couple d'ouverture en raison de la direction oppos\u00e9e de la pression moyenne et de la force d'\u00e9tanch\u00e9it\u00e9, et de la contrainte maximale. sur la tige de valve se trouve la contrainte de pression, il doit donc y avoir une r\u00e9sistance et une rigidit\u00e9 suffisantes, sinon la tige de valve sera d\u00e9form\u00e9e.<\/p>\n\n\n\n
Par cons\u00e9quent, lorsque la taille du robinet \u00e0 soupape est sup\u00e9rieure \u00e0 DN150 (NPS 6), afin de r\u00e9duire le couple de fonctionnement de la vanne et de r\u00e9duire le diam\u00e8tre de la tige de la vanne, le fluide s'\u00e9coule g\u00e9n\u00e9ralement vers la partie sup\u00e9rieure du disque de la vanne. pour entrer (entr\u00e9e haute et sortie basse). \u00c0 ce stade, la direction de la pression moyenne et de la force d\u2019\u00e9tanch\u00e9it\u00e9 est la m\u00eame. Sous l'action d'une pression moyenne, la valve peut \u00eatre scell\u00e9e plus facilement. Le couple de fermeture diminue et le couple d'ouverture augmente, la contrainte maximale sur la tige de vanne est une contrainte de traction et le diam\u00e8tre de la tige de vanne peut \u00eatre r\u00e9duit en cons\u00e9quence.<\/p>\n\n\n\n
Lorsque le robinet \u00e0 soupape est ouvert, lorsque la hauteur d'ouverture du disque atteint 25-30% de la taille nominale de la vanne, le d\u00e9bit a atteint le maximum, c'est-\u00e0-dire que la vanne a atteint la position compl\u00e8tement ouverte, donc la position compl\u00e8tement ouverte du robinet \u00e0 soupape doit \u00eatre d\u00e9termin\u00e9 en fonction de la course du disque.<\/p>\n\n\n\n
Lorsque le robinet \u00e0 soupape est ferm\u00e9 et rouvert, il est similaire au robinet-vanne \u00e0 joint forc\u00e9, c'est-\u00e0-dire qu'une fois le robinet ferm\u00e9, une force de fonctionnement suffisante doit \u00eatre appliqu\u00e9e sur la surface d'\u00e9tanch\u00e9it\u00e9 pour obtenir l'effet d'\u00e9tanch\u00e9it\u00e9. Par cons\u00e9quent, le couple de fermeture de la vanne doit \u00eatre augment\u00e9 jusqu'\u00e0 la valeur sp\u00e9cifi\u00e9e en fonction du couple de fonctionnement. Lorsque la vanne est \u00e0 nouveau ouverte, le couple d'ouverture de la vanne est g\u00e9n\u00e9ralement sup\u00e9rieur au couple de fermeture en raison de l'influence du frottement statique, de la dilatation thermique et d'autres facteurs. Ainsi, la vanne peut \u00eatre ouverte de mani\u00e8re fiable et doit \u00eatre prise en compte dans le conception.<\/p>\n\n\n\n
Afin de r\u00e9duire la pression d'impact \u00e9lev\u00e9e form\u00e9e dans la vanne d'ouverture et de fermeture, le robinet \u00e0 soupape doit fonctionner lentement, en un sens, il doit avoir un taux de changement coh\u00e9rent avec le d\u00e9bit.<\/p>\n\n\n\n
Le couple de fonctionnement du robinet \u00e0 soupape pr\u00e9sente les caract\u00e9ristiques suivantes\u00a0:<\/h2>\n\n\n\n"Ouvertures d'entr\u00e9e basses et de sortie hautes"<\/strong><\/h3>\n\n\n\nLorsque \u00ab entr\u00e9e basse et sortie haute \u00bb est adopt\u00e9e, la vanne est ferm\u00e9e \u00e0 partir de la position compl\u00e8tement ouverte. La r\u00e9sistance que la force de fonctionnement doit vaincre est la r\u00e9sistance au frottement de la tige et de la garniture ainsi que la pouss\u00e9e provoqu\u00e9e par la pression moyenne sur la section du disque (axiale). Avec la chute du disque de valve, la diff\u00e9rence de pression entre l'avant et l'arri\u00e8re du disque de valve se forme, ce qui emp\u00eache le disque de valve de tomber, et la r\u00e9sistance augmentera rapidement avec la chute du disque de valve. Avec la vanne compl\u00e8tement ferm\u00e9e, une force d'\u00e9tanch\u00e9it\u00e9 forc\u00e9e est appliqu\u00e9e par la tige de vanne, et la diff\u00e9rence de pression entre l'avant et l'arri\u00e8re du disque de vanne atteint la pression de service maximale du fluide, \u00e0 ce moment, la tige de vanne supporte le maximum couple de fermeture.<\/p>\n\n\n\n
Lors de l'ouverture de la vanne, pression moyenne ou pouss\u00e9e provoqu\u00e9e par la diff\u00e9rence de pression entre l'avant et l'arri\u00e8re du disque, identique \u00e0 la direction de fermeture de la vanne. Cependant, il convient de noter qu'au moment de l'ouverture, le couple de manoeuvre d'ouverture peut d\u00e9passer le couple de fermeture en raison du couple de friction statique important entre les surfaces d'\u00e9tanch\u00e9it\u00e9.<\/p>\n\n\n\n
\u00ab\u00a0Ouvertures d'entr\u00e9e \u00e9lev\u00e9es et de sorties basses\u00a0\u00bb<\/strong><\/h3>\n\n\n\nLorsque \u00ab\u00a0entr\u00e9e \u00e9lev\u00e9e et sortie basse\u00a0\u00bb est adopt\u00e9e, la vanne est ferm\u00e9e \u00e0 partir de la position compl\u00e8tement ouverte. Les deux forces ci-dessus sont encore n\u00e9cessaires pour vaincre la force op\u00e9rationnelle. Avec la diminution du disque de vanne, la diff\u00e9rence de pression avant et apr\u00e8s le disque de vanne favorise la fermeture de la vanne avant la fermeture de la vanne.<\/p>\n\n\n\n
Lorsque la vanne est ouverte, la situation est exactement le contraire. La pouss\u00e9e provoqu\u00e9e par la pression moyenne et la diff\u00e9rence de pression entre l'avant et l'arri\u00e8re du disque est oppos\u00e9e au sens d'ouverture de la vanne, de sorte que le couple de fonctionnement requis pour le processus d'ouverture de la vanne est beaucoup plus grand que le couple de fermeture.<\/p>\n\n\n\n\n

Avec la chute du disque de valve, la diff\u00e9rence de pression entre l'avant et l'arri\u00e8re du disque de valve se forme, ce qui emp\u00eache le disque de valve de tomber, et la r\u00e9sistance augmentera rapidement avec la chute du disque de valve.

Caract\u00e9ristiques de fonctionnement<\/strong> de robinet \u00e0 soupape<\/h2>\n\n\n\nLa forme d'\u00e9tanch\u00e9it\u00e9 du robinet \u00e0 soupape est une \u00e9tanch\u00e9it\u00e9 forc\u00e9e. Lorsque la vanne est ferm\u00e9e, une force suffisante doit \u00eatre appliqu\u00e9e sur le disque de la vanne pour obtenir l'effet d'\u00e9tanch\u00e9it\u00e9, et l'\u00e9tanch\u00e9it\u00e9 ne peut \u00eatre r\u00e9alis\u00e9e que lorsque la pression sp\u00e9cifique est suffisante.<\/p>\n\n\n\n
La force d'\u00e9tanch\u00e9it\u00e9 et la pression moyenne sont sur le m\u00eame axe. Lorsque le fluide entre par la partie inf\u00e9rieure du disque de la vanne (entr\u00e9e basse et sortie haute), le couple de fermeture de la vanne est sup\u00e9rieur au couple d'ouverture en raison de la direction oppos\u00e9e de la pression moyenne et de la force d'\u00e9tanch\u00e9it\u00e9, et de la contrainte maximale. sur la tige de valve se trouve la contrainte de pression, il doit donc y avoir une r\u00e9sistance et une rigidit\u00e9 suffisantes, sinon la tige de valve sera d\u00e9form\u00e9e.<\/p>\n\n\n\n
Par cons\u00e9quent, lorsque la taille du robinet \u00e0 soupape est sup\u00e9rieure \u00e0 DN150 (NPS 6), afin de r\u00e9duire le couple de fonctionnement de la vanne et de r\u00e9duire le diam\u00e8tre de la tige de la vanne, le fluide s'\u00e9coule g\u00e9n\u00e9ralement vers la partie sup\u00e9rieure du disque de la vanne. pour entrer (entr\u00e9e haute et sortie basse). \u00c0 ce stade, la direction de la pression moyenne et de la force d\u2019\u00e9tanch\u00e9it\u00e9 est la m\u00eame. Sous l'action d'une pression moyenne, la valve peut \u00eatre scell\u00e9e plus facilement. Le couple de fermeture diminue et le couple d'ouverture augmente, la contrainte maximale sur la tige de vanne est une contrainte de traction et le diam\u00e8tre de la tige de vanne peut \u00eatre r\u00e9duit en cons\u00e9quence.<\/p>\n\n\n\n
Lorsque le robinet \u00e0 soupape est ouvert, lorsque la hauteur d'ouverture du disque atteint 25-30% de la taille nominale de la vanne, le d\u00e9bit a atteint le maximum, c'est-\u00e0-dire que la vanne a atteint la position compl\u00e8tement ouverte, donc la position compl\u00e8tement ouverte du robinet \u00e0 soupape doit \u00eatre d\u00e9termin\u00e9 en fonction de la course du disque.<\/p>\n\n\n\n
Lorsque le robinet \u00e0 soupape est ferm\u00e9 et rouvert, il est similaire au robinet-vanne \u00e0 joint forc\u00e9, c'est-\u00e0-dire qu'une fois le robinet ferm\u00e9, une force de fonctionnement suffisante doit \u00eatre appliqu\u00e9e sur la surface d'\u00e9tanch\u00e9it\u00e9 pour obtenir l'effet d'\u00e9tanch\u00e9it\u00e9. Par cons\u00e9quent, le couple de fermeture de la vanne doit \u00eatre augment\u00e9 jusqu'\u00e0 la valeur sp\u00e9cifi\u00e9e en fonction du couple de fonctionnement. Lorsque la vanne est \u00e0 nouveau ouverte, le couple d'ouverture de la vanne est g\u00e9n\u00e9ralement sup\u00e9rieur au couple de fermeture en raison de l'influence du frottement statique, de la dilatation thermique et d'autres facteurs. Ainsi, la vanne peut \u00eatre ouverte de mani\u00e8re fiable et doit \u00eatre prise en compte dans le conception.<\/p>\n\n\n\n
Afin de r\u00e9duire la pression d'impact \u00e9lev\u00e9e form\u00e9e dans la vanne d'ouverture et de fermeture, le robinet \u00e0 soupape doit fonctionner lentement, en un sens, il doit avoir un taux de changement coh\u00e9rent avec le d\u00e9bit.<\/p>\n\n\n\n
Le couple de fonctionnement du robinet \u00e0 soupape pr\u00e9sente les caract\u00e9ristiques suivantes\u00a0:<\/h2>\n\n\n\n"Ouvertures d'entr\u00e9e basses et de sortie hautes"<\/strong><\/h3>\n\n\n\nLorsque \u00ab entr\u00e9e basse et sortie haute \u00bb est adopt\u00e9e, la vanne est ferm\u00e9e \u00e0 partir de la position compl\u00e8tement ouverte.

Lors de l'ouverture de la vanne, pression moyenne ou pouss\u00e9e provoqu\u00e9e par la diff\u00e9rence de pression entre l'avant et l'arri\u00e8re du disque, identique \u00e0 la direction de fermeture de la vanne.

Flow direction of Globe Valves<\/h2>\r\n\r\n\r\n\r\n\r\nFor applications with low temperatures, Globe valves are normally installed so that the pressure is under the disc. This contributes to an easy operation and helps protect the packing.\r\n\r\n\r\n\r\n\r\n\r\nFor applications with high-temperature steam service, Globe valves are installed so that the pressure is above the disk. Otherwise, the stem will contract upon cooling and tend to lift the disk off the seat.\r\n\r\n\r\n\r\n\r\n
Typical Applications of Globe valves<\/h2>\r\n\r\n\r\n\r\n\r\nThe following are some of the typical applications of Globe valves..\r\n\r\n\r\n\r\n\r\n

China Angle Globe Valve<\/a><\/strong><\/h2>\r\n\r\n\r\n\r\n\r\nThe angle globe valve is a modification of the basic standard pattern globe valve where the ends are at an angle of 90 degrees.\r\n\r\n\r\n\r\n\r\n\r\nA variation on the straight globe valve, angle globe valves\u2019 have a design that encourages the media to flow at a 90\u00b0 angle, thus generating a lesser pressure drop. Preferred for regulating liquid or air media, angle globe valves are also ideal for applications that require pulsating flow due to their superior slugging effect capability.\r\n\r\n\r\n\r\n\r\n\r\nWith over 20 years of production expertise and employing the latest in manufacturing technology, ZECO is your supplier of choice for quality angle globe valves.
