德國(guó)巴赫進(jìn)口燃?xì)?/span>截止閥概述：Overview of Bach imported gas globe valve in germany:

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。

Imported gas cut-off valve is a kind of gas valve, also known as liquefied petroleum gas stop valve (liquefied petroleum gas valve). This product has the function of pressure resistance and corrosion resistance. It is used in the liquefied petroleum gas storage of the city, and also used in the liquefied petroleum gas system of the refinery, petrochemical plant and petrochemical plant, as the cool device of the cutting and closing of the dielectric section.
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(dòng)密封泄漏時(shí)，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(chǎng)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(guò)載不受損，延長(zhǎng)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。

進(jìn)口燃?xì)饨刂归y的定義：Definition of imported gas globe valve:

1、手輪順時(shí)針?lè)较蜣D(zhuǎn)時(shí),閥桿向下移動(dòng),閥瓣下降使密封面密合,將通路切斷.逆轉(zhuǎn)時(shí)則開(kāi)啟,閥桿提到較高點(diǎn)上密封起作用。   
2、本閥門增加了一個(gè)上密封.在閥門開(kāi)啟狀態(tài)時(shí),與填料一起兩層密封作用,并對(duì)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(wú)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(dòng)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(shí)，利用一個(gè)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(shí)，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:

2、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.    

3、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

4、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.

5、4, the sealing performance of the media with the increase in pressure, which has self sealing performance, without manual maintenance.

6、5, fireproof structure: when the soft sealing material is burned, the metal sealing surface can remain sealed, avoid the spread of fire.

7、6, using elastic V shaped Teflon or nitrile rubber as sealing filler, the filler cap, stainless steel spring provides initial seal.

8、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.

9、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.

10、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.
