是防止天燃?xì)狻⒁夯蜌夤苈分械慕橘|(zhì)倒流的閥門。的啟閉件靠介質(zhì)流動(dòng)和力量自行開啟或關(guān)閉，采用了聚四烯為密封面的材料，利用聚四烯在介質(zhì)壓力作用下產(chǎn)生的微量變形，提高了密封性能，減緩介質(zhì)壓力的沖擊，防止靜電而產(chǎn)生了火花，保護(hù)燃?xì)忾y門及燃?xì)夤艿溃m用燃?xì)夤艿揽刂平油ê筒脭喙苈方橘|(zhì)的啟閉裝置，阻止介質(zhì)逆流。
Gas check valve is to prevent backflow of natural gas, liquefied petroleum gas pipeline in the medium valve. Inlet check valve opening and closing pieces by medium flow and the forces to open or close, use teflon as the sealing surface material, micro deformation produced in the medium under pressure using Teflon, improves the sealing performance, slow medium pressure, anti electrostatic and spark, gas valve and protection gas pipeline, the opening and closing device for a gas pipeline control switching on and cutting medium line, prevent the media counter.
1、當(dāng)流體順著箭頭方向通過該閥門時(shí),由于流體的壓差使閥瓣升起,從而流體順利的通過閥門
2、當(dāng)流體倒流時(shí),由于閥瓣的自重和流體的壓差作用,使閥瓣下降并與密封面密合.防止了流體倒流
3、利用流體壓差和自身的重量實(shí)現(xiàn)升降，阻力小。
4、采用了聚四烯或尼龍塑料為密封面的材料，提高了內(nèi)部密封性能。
5、為全封閉結(jié)構(gòu),無動(dòng)密封,*外泄.
