進(jìn)口液化氣截止閥品牌德國(guó)洛克精工細(xì)作

進(jìn)口液化氣截止閥結(jié)構(gòu)特點(diǎn)：

1、開(kāi)關(guān)輕松，密封性能好

2、閥桿填料自動(dòng)密封：填料采用(PTFE+丁睛橡膠)復(fù)合軟成形填料，增加彈簧自動(dòng)補(bǔ)償，利用管道壓力產(chǎn)生自動(dòng)密封，密封填料磨損彈簧自動(dòng)補(bǔ)償。

3、密封填料損壞可帶壓更換填料。(手輪逆時(shí)針萬(wàn)向轉(zhuǎn)到頂點(diǎn)上密封產(chǎn)生密封，拿下手輪，松開(kāi)填料室、拿下填料，更換復(fù)合軟成形填料（PDFE+丁晴橡膠+彈簧)。

4、閥桿耐磨功能：填料室增加PDFE，使閥桿不會(huì)和填料室摩擦，增強(qiáng)閥桿使用壽命。

5、開(kāi)啟時(shí)將閥桿提到點(diǎn)，令填料與上密封同時(shí)起密封作用，關(guān)閉時(shí)關(guān)閉力不要過(guò)大，以免破壞密封面。

進(jìn)口液化氣截止閥規(guī)格參數(shù)：

A、公稱通徑：15∽200（mm)

B、壓力等級(jí)：16Bar-40Bar                         

C、溫度范圍：-20℃～120℃

D、閥體材質(zhì):碳鋼,不銹鋼

E、適用介質(zhì):天然氣,燃?xì)?/span>,液化, 煤氣

F、操作方式:手動(dòng)

進(jìn)口液化氣截止閥工作原理:

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*點(diǎn)上密封起作用。

2、本閥門(mén)增加了一個(gè)上密封.在閥門(mén)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(mén)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。

Working principle of the imported LPG stop valve:
1. When the handwheel turns clockwise, the valve stem moves downward, the valve disc drops to close the sealing surface, and cuts off the passage. When reversing, it opens, and the valve stem is sealed at the highest point.
2. This valve has an upper seal. When the valve is open, it has two sealing functions with packing, and has certain protection effect on the packing.
3. The valve adopts nylon products as sealing surface, the packing is soft forming packing, and the upper seal is also soft material, and the sealing performance is good.
                                                                               

進(jìn)口液化氣截止閥產(chǎn)品簡(jiǎn)介:

液化氣截止閥采用彈性成型聚四氟乙烯為填料，填料密封性能隨介質(zhì)壓力上升而增強(qiáng)，并具備倒密封功能，適用于高中壓燃?xì)廨斔凸苈?。適用介質(zhì)：天然氣、液化氣，適用溫度-40∽+80℃。

Introduction to the imported LPG stop valve products:
The LPG stop valve adopts elastic shaped polytetrafluoroethylene as the packing, and the sealing performance of the packing increases with the increase of the medium pressure, and has the function of reverse sealing, which is suitable for the high and medium pressure gas transmission pipeline. Applicable medium: natural gas and liquefied gas, applicable temperature is -40 ∽ 80 ℃.
