氧氣截止閥的使用特點(diǎn)介紹

1、對(duì)于公稱壓力PN≥1.6MPa、DNl25~200采用內(nèi)旁通結(jié)構(gòu);DN250~500采用帶外旁通閥結(jié)構(gòu)。其目的是減小閥前、閥后的壓力差以避免高流速、高沖刷以及防止產(chǎn)生高溫,氧氣管網(wǎng)的安全運(yùn)行,同時(shí)也減小了操作力矩。
1. For nominal pressure PN ≥ 1.6MPa and DNl25-200, an internal bypass structure is used; DN250-500 adopts an external bypass valve structure. The purpose is to reduce the pressure difference between the front and back of the valve to avoid high flow velocity, high erosion, and prevent the generation of high temperatures, ensuring the safe operation of the oxygen pipeline network, while also reducing the operating torque.
2、介質(zhì)流向:PN≥1.6MPa、DN≤100介質(zhì)由閥瓣下方流入閥瓣上方(即低進(jìn)高出),DN≥125介質(zhì)由閥瓣卜方流入下方(高進(jìn)低出)o對(duì)于DN≥125的閥門采用介質(zhì)高進(jìn)低出的流向,一方面足內(nèi)旁通閥結(jié)構(gòu)上的需要,另一方面由于介質(zhì)壓力的作用使閥門的關(guān)閉力減小。
2. Medium flow direction: PN ≥ 1.6MPa, DN ≤ 100 medium flows from below the valve disc to above the valve disc (i.e. low inlet and high outlet), DN ≥ 125 medium flows from the valve disc to below (high inlet and low outlet). For valves with DN ≥ 125, the medium flow direction is high inlet and low outlet, which meets the structural requirements of the bypass valve and reduces the closing force of the valve due to the pressure of the medium.
3、該閥設(shè)有導(dǎo)靜電安全裝置,可避免因靜電產(chǎn)生火花。

3. This valve is equipped with an electrostatic safety device to avoid sparks caused by static electricity.
4、與普通截止閥相比,氧氣管路用截止閥的支架部分采用全封閉式結(jié)構(gòu),且壓緊填料時(shí)可以打開支架上的防護(hù)蓋板,起到了防油防塵的作用。并有明顯的禁油標(biāo)記。
4. Compared with ordinary globe valves, the bracket part of the globe valve for oxygen pipelines adopts a fully enclosed structure, and the protective cover plate on the bracket can be opened when pressing the packing, playing a role in preventing oil and dust. And there is a clear oil ban mark.
5、全部零件采用嚴(yán)格的脫脂處理。
5. All parts undergo strict degreasing treatment.
6、防燃阻火:主要部件的材質(zhì)為阻燃性極好的銅合金,屬不可燃材料,即使與高速氣流中的固體粒子碰撞也不會(huì)產(chǎn)生火花。因此,本閥具有防燃阻火性能
6. Flame retardant and flame retardant: The main components are made of copper alloy with excellent flame retardancy, which is a non combustible material and will not generate sparks even when colliding with solid particles in high-speed airflow. Therefore, this valve has flame retardant and flame retardant performance
7、安全可靠:本閥帶有防塵、防水、防油污裝置,所有與氧氣接觸的閥件在組裝前均經(jīng)過嚴(yán)格脫脂和禁油措施,填料材質(zhì)為聚四氟乙烯,可確保使用時(shí)安全可靠。
7. Safe and reliable: This valve is equipped with dust, water, and oil resistant devices. All valve components in contact with oxygen undergo strict degreasing and oil prohibition measures before assembly. The packing material is polytetrafluoroethylene, which can ensure safety and reliability during use.
