ZSH Shanghai Valve Manufzcturing Co.,LTD.

Oxygen pipeline flame arrester and oxygen pipeline valve before and after the flame arrester is the use of special copper alloy and stainless steel welding. It can effectively prevent the oxygen pipe valve is easy to form in the suddenly opened when "adiabatic compression", the local temperature rises, become the ignition energy; can prevent the valve before and after the pressure under the action of high speed particles (such as dust, rust, welding slag, etc.) and friction valve after the piping impact become spark ignition energy. The use of a flame arrester can quickly block the fire, to prevent the occurrence of explosion accident of gas pipeline. Series of products are widely used in metallurgy, chemical industry, oxygen pipeline, customers can directly to the appropriate parts of this product and the oxygen pipeline welding operation can be connected.
ZHQ-YQ series products are widely used in metallurgy, chemical industry, oxygen pipeline, customers can directly to the appropriate parts of this product and the oxygen pipeline welding operation can be connected.
Our company introduced advanced technology and comprehensive in Britain, Germany and other companies, with advanced processing equipment and perfect detection device, explosion-proof corrugated Zuhuo production, has the advantages of compact structure, high reliability, fire core explosion-proof, anti-corrosion, fire resistance, easy cleaning and other advantages, especially suitable for hydrogen. Nitrogen, oxygen, liquefied gas and other special medium. The product has reasonable structure, beautiful shape, fire resistant layer core made of stainless steel material, strong corrosion resistance, resistance of fire, explosion and other technical performance has prominent advantages.

大多数阻火器是由能够通过气体的许多细小、均匀或不均匀的通道或孔隙的固体材质所组成，对这些通道或孔隙要求尽量的小，小到只要能够通过火焰就可以。这样，火焰进入阻火器后就分成许多细小的火焰流被熄灭。火焰能够被熄灭的机理是传热作用和器壁效应。
