Materiais usados para v\u00e1lvula esf\u00e9rica de a\u00e7o forjado com sede de metal<\/h2>\n\n\n\n
Deve ser capaz de atender \u00e0 press\u00e3o do meio local e \u00e0s propriedades mec\u00e2nicas do meio. O material precisa ter capacidade de resistir \u00e0s propriedades qu\u00edmicas e f\u00edsicas do meio, e tamb\u00e9m precisa considerar a economia da v\u00e1lvula.<\/p>\n\n\n\n
Em alguns ambientes de m\u00eddia, materiais de baixo custo podem ser selecionados para evitar desperd\u00edcios. Em alguns ambientes de alta temperatura e alta press\u00e3o, \u00e9 necess\u00e1rio selecionar materiais resistentes a altas temperaturas e de alto custo para atender ao ambiente de uso no local.<\/p>\n\n\n\n
No uso em campo, ele precisa atender aos requisitos de instala\u00e7\u00e3o confi\u00e1vel e a\u00e7\u00e3o flex\u00edvel e confi\u00e1vel. Tudo isso \u00e9 indissoci\u00e1vel do controle do processo produtivo. Como a v\u00e1lvula possui muitas pe\u00e7as e uma estrutura complexa, diferentes pe\u00e7as s\u00e3o completadas por diferentes t\u00e9cnicas de processamento. Como fundi\u00e7\u00e3o, forjamento, usinagem, tratamento t\u00e9rmico, soldagem e outros processos.<\/p>\n\n\n\n
Os m\u00e9todos de inspe\u00e7\u00e3o de pe\u00e7as fabricadas por diferentes processos tamb\u00e9m s\u00e3o diferentes. Por exemplo, as pe\u00e7as forjadas s\u00e3o inspecionadas principalmente por testes n\u00e3o destrutivos, enquanto o tratamento t\u00e9rmico \u00e9 inspecionado por testes de dureza.<\/p>\n\n\n\n
De modo geral, a qualidade de fabrica\u00e7\u00e3o de v\u00e1lvulas dos fabricantes de v\u00e1lvulas de a\u00e7o forjado inclui a qualidade da pe\u00e7a bruta, requisitos de tamanho de processamento, rugosidade da superf\u00edcie e requisitos de precis\u00e3o de instala\u00e7\u00e3o.<\/p>\n\n\n

<\/figure>\n<\/div>\n\n\nTeste de press\u00e3o da v\u00e1lvula esf\u00e9rica de a\u00e7o forjado com sede de metal<\/h2>\n\n\n\n
Este \u00e9 um teste essencial para todas as v\u00e1lvulas. Ao realizar um teste de press\u00e3o na v\u00e1lvula, o inspetor deve verificar cuidadosamente e o tempo de reten\u00e7\u00e3o e a press\u00e3o devem atender aos requisitos.<\/p>\n\n\n\n
Para melhorar a velocidade de produ\u00e7\u00e3o, alguns fabricantes de v\u00e1lvulas de a\u00e7o forjado encurtam o tempo de reten\u00e7\u00e3o de press\u00e3o da v\u00e1lvula ou n\u00e3o atendem aos requisitos padr\u00e3o, resultando em uma inspe\u00e7\u00e3o imprecisa do teste de press\u00e3o da v\u00e1lvula. Existem tamb\u00e9m alguns inspetores que n\u00e3o entendem o teste de inspe\u00e7\u00e3o da veda\u00e7\u00e3o superior realizado durante a inspe\u00e7\u00e3o de press\u00e3o e confundem a veda\u00e7\u00e3o superior e a estrutura da embalagem.<\/p>\n\n\n\n
Na verdade, o teste de veda\u00e7\u00e3o superior serve principalmente para testar a veda\u00e7\u00e3o r\u00edgida c\u00f4nica e esf\u00e9rica entre a haste da v\u00e1lvula esf\u00e9rica de a\u00e7o forjado e a sede da veda\u00e7\u00e3o superior com base na v\u00e1lvula que est\u00e1 totalmente aberta.<\/p>\n\n\n\n
Recomenda\u00e7\u00f5es para teste de press\u00e3o: Ao procurar vazamentos, o inspetor n\u00e3o pode utilizar a curva de press\u00e3o como crit\u00e9rio para falha da v\u00e1lvula, mas precisa analisar a v\u00e1lvula, para encontrar com precis\u00e3o o local do vazamento e analisar a causa.<\/p>\n\n\n\n
O trabalho estat\u00edstico deve ser realizado para pontos de vazamento, prestar aten\u00e7\u00e3o para compreender a localiza\u00e7\u00e3o de vazamento f\u00e1cil e fornecer feedback oportuno \u00e0s unidades relevantes. Para a opera\u00e7\u00e3o dos inspetores, deve ser seguro e confi\u00e1vel. \u00c9 necess\u00e1rio permitir que os inspetores entendam o princ\u00edpio do experimento de press\u00e3o para que possam interpretar o experimento de press\u00e3o com mais precis\u00e3o.<\/p>\n\n\n\n\n

What Is Shot Blasting Machine?<\/h2>\r\n\r\n\r\n\r\n\r\nA shot blasting machine is a surface preparation equipment in which the steel grits\/steel shots are accelerated and thrown on the surface of a material object at high speed by means of blasting turbines. In the 1930s, American companies made the world\u2019s first shot-blasting machine. The production of shot blasting equipment in China began in the 1950s and was largely based on Soviet technology.\r\n\r\n\r\n\r\n\r\n
What is Shot Blasting Machine Used For?<\/h2>\r\n\r\n\r\n\r\n\r\nWheel blast machines can also be used to remove burrs, diaphragms, and rust that may affect the integrity, appearance, or definition of an object\u2019s parts. The machine can also target a partially coated surface to remove surface contaminants and provide a surface profile that increases the coating\u2019s adhesion to the surface for the purpose of shot-blasting the workpiece. A shot peening machine differs from a wheel blasting machine in that it is used to reduce the fatigue life of a part by increasing different surface stresses, increasing the strength of a part, or preventing micromotion. Shot blasting machines are primarily used to treat the surface of steel products in large quantities during the steel production process. The use of a shot blasting machine can effectively remove burrs on the surface of steel products, as well as some large-scale rust, in the use of shot blasting machines, if not mastering the technology, is likely to cause the integrity of the surface of steel products, the light will cause surface abrasions, and serious will cause a serious poor appearance, affecting the product image.\r\n\r\n\r\n\r\n\r\n\r\nFor steel production, a shot blasting machine is inevitable equipment, and the use of a shot blasting machine for steel sand as well as steel shot surface treatment, is also an essential process, as the removal of steel sand, steel shot surface stains, rust, and a necessary procedure to check the integrity of the product surface, is essential.\r\n\r\n\r\n\r\n\r\n
Functions of Shot Blasting Machine<\/h2>\r\n\r\n\r\n\r\n\r\nCan remove the cast steel, cast iron surface of the oxide skin or sticky sand, the surface of the casting to play a role in cleaning, but also the quality of the castings for inspection of a necessary step, the large turbine casing to go in front of the line after shot blasting to detect injuries, so as to ensure reliable results. Hook-type blast machine is divided into single-hook and double-hook, hook-type blast machines by two hook-loading workpieces alternately into the blast cleaning room. The shot blast machine is used to throw 0.2 to 0.8 pellets to the surface of the workpiece, making the surface of the workpiece to a certain roughness, making the workpiece beautiful, or changing the compressive stress of the workpiece to improve the life of the workpiece. For the castings, shot blasting is the necessary process to discover the existence of the surface of the skin, the skin of the pores, and other defects, through shot blasting can ensure that the casting has a high quality.\r\n\r\n\r\n\r\n\r\n\r\nIn the modern theory of the strength of metals, as long as the density of the internal dislocation of the metal can be increased, the strength of the metal can be increased, and the use of a blasting machine blast to enhance the dislocation of the structure, which can help to improve the strength of the metal, this way is very effective for those who can not use the phase change of the hardened metal.\r\n\r\n\r\n\r\n\r\n\r\nThe shot-blasting can form compressive stress on the surface of the casting, which can make the castings of tensile strength, corrosion resistance, and fatigue strength have been enhanced, but also to correct those distorted thin-walled castings, can replace the ordinary hot and cold forming process, on large thin-walled castings to process, to avoid those residual tensile stress to obtain useful compressive stress.\r\n\r\n\r\n\r\n\r\n
