進(jìn)口燃?xì)?/span>截止閥

德國巴赫進(jìn)口燃?xì)?/span>截止閥概述：

進(jìn)口燃?xì)饨刂归y屬于燃?xì)忾y門中的一種，也可稱液化氣截止閥(液化氣閥門)。本產(chǎn)品有耐壓、耐腐蝕作用，使用于城市液化氣石油氣貯備站，也使用于煉油廠、石油化工廠、石油化工廠的液化氣系統(tǒng)，作為控制介質(zhì)截的啟閉裝置。
進(jìn)口燃?xì)饨刂归y采用成形聚四氟乙烯/柔性石墨作為密封填料，由填料壓蓋提供初始密封，當(dāng)發(fā)生磨損引起的動密封泄漏時，可用填料壓蓋螺母進(jìn)行調(diào)整，適用于大多數(shù)高中壓非腐蝕性流體輸送場合。在閥瓣的金屬密封面上設(shè)置一溝槽，鑲裝一軟密封環(huán)與閥座金屬密封面形成軟硬雙重密封結(jié)構(gòu)，提高了密封性能，避免了金屬密封旋轉(zhuǎn)摩擦產(chǎn)生靜電，引起的火花。金屬硬密封面保護(hù)軟密封材料過載不受損，延長閥門使用壽命。適用于石油、化工、鋼鐵、水力、電力等行業(yè)。閥座密封面材料為尼龍塑料。

Imported gas stop valve

Overview of German Bach imported gas valve:

Imported gas valve is a gas valve, also known as liquefied petroleum gas stop valve (liquefied petroleum gas valve). This product has the pressure resistance, corrosion resistance, used in City liquefied petroleum gas storage station, liquefied gas system is also used in oil refineries, chemical plants, petrochemical plants, as the opening and closing device control medium cut.

Imported gas cut-off valve by forming PTFE / graphite as packing, the packing gland provides initial seal, when the wear caused by dynamic seal leakage, can adjust gland nuts, suitable for most high pressure conveying non corrosive fluid. A groove in the valve metal sealing surface, insert a soft sealing ring and the valve seat sealing surface of metal forming and double seal structure, the sealing performance is improved, avoiding the metal seal rotating friction caused by electrostatic spark. Metal hard sealing cover to protect the soft sealing material overload is not damaged, extend the service life of the valve. Suitable for petroleum, chemical, iron and steel, hydraulic, electric power and other industries. Seat sealing surface material for nylon plastic.

進(jìn)口燃?xì)饨刂归y的定義：   

1. 手輪順時針方向轉(zhuǎn)時,閥桿向下移動,閥瓣下降使密封面密合,將通路切斷.逆轉(zhuǎn)時則開啟,閥桿提到zui高點上密封起作用。   
   2、本閥門增加了一個上密封.在閥門開啟狀態(tài)時,與填料一起兩層密封作用,并對填料有一定的保護(hù)作用  
   3、本閥門采用尼龍制品作密封面,填料為軟成形填料,上密封也為軟材質(zhì),密封性能較好。
   4、填料密封性能隨介質(zhì)壓力上升而增強(qiáng)，即具有自密封性能，無需人工維護(hù)。
   5、防火結(jié)構(gòu)：當(dāng)軟密封材料被燒壞后，金屬密封面仍能保持密封，避免火災(zāi)擴(kuò)大。
   6、采用彈性V形聚四氟乙烯或丁qing橡膠作為動密封填料，由填料蓋、不銹鋼彈簧提供初始密封。
   7、閥座密封面材料為尼龍塑料提高了密封性能，避免了金屬密封旋轉(zhuǎn)摩擦產(chǎn)生靜電，引起的火花。
   8、防靜電結(jié)構(gòu)：當(dāng)閥門的內(nèi)密封體旋轉(zhuǎn)摩擦產(chǎn)生靜電時，利用一個導(dǎo)電裝置和大地連通，從而避免靜電導(dǎo)致天然氣火災(zāi)。
   9、當(dāng)閥門外部失火時，軟密封材料被高溫?zé)龤?，其金屬密封仍能保證閥門緊閉密封，從而形成了軟硬雙重密封結(jié)構(gòu)，密封性能好。

The definition of imported gas valve:

1. 1, hand wheel clockwise rotation, the valve stem to move down, the valve flap to close the sealing surface, cut off the path. When the reverse is open, the valve stem to mention the highest point on the seal effect.    
2. 2, the addition of a valve on the seal. In the valve open state, and filling the role with two seals, and the protective effect of on the filler
3. 3, the valve with nylon products for sealing cover, packing for the soft forming filler, the seal is also soft material, sealing performance is better.
4. 4, the sealing performance of the media with the increase in pressure, which has self sealing performance, without manual maintenance.
5. 5, fireproof structure: when the soft sealing material is burned, the metal sealing surface can remain sealed, avoid the spread of fire.
6. 6, using elastic V shaped Teflon or nitrile rubber as sealing filler, the filler cap, stainless steel spring provides initial seal.
7. 7, the valve seat sealing surface material for nylon plastic to improve the sealing performance, to avoid the metal seal rotary friction produce static electricity, caused by sparks.
8. 8, anti-static structure: when the valve inside the seal body to produce static friction rotation, the use of a conductive device and the earth to connect, so as to avoid static electricity caused by natural gas fire.
9. 9, when the valve outside the fire, the soft sealing material was burned at high temperature, the metal seal can still ensure that the valve closed and sealed, thus forming a double seal structure of hard and soft, good sealing performance.
