進(jìn)口天然氣截止閥德國(guó)洛克《DE LOCKE》現(xiàn)貨供應(yīng)

 一、進(jìn)口天然氣截止閥描述：

德國(guó)《LOCKE》洛克進(jìn)口天然氣截止閥（Natural gas globe valve）采用成形聚四氟乙烯/柔性石墨作為密封填料，啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿閥座的中心線作直線運(yùn)動(dòng)的截止閥，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。進(jìn)口天然氣截止閥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),作為控制天然氣介質(zhì)的啟閉裝置。

Natural gas globe valve imported from Locke, Germany Valve) the formed polytetrafluoroethylene / flexible graphite is used as the sealing packing, the opening and closing parts are plug-shaped valve disc, the sealing surface is flat or conical, the valve disc moves in a straight line along the center line of the valve seat, the initial sealing is provided by the packing gland, when the dynamic sealing leakage caused by wear occurs, the packing gland nut can be used for adjustment. The imported natural gas stop valve is used in the City liquefied petroleum gas storage station, as well as in the liquefied gas system of refineries, petrochemical plants and petrochemical plants, as the opening and closing device for controlling the natural gas medium.

三、進(jìn)口天然氣截止閥結(jié)構(gòu)優(yōu)點(diǎn)：

密封面間磨擦力小

防火防靜電結(jié)構(gòu)

耐磨損,耐腐蝕,壽命長(zhǎng)

尼龍閥瓣,有彈性密封更可靠

工作行程小，啟閉時(shí)間短

填料壓蓋螺母進(jìn)行調(diào)整,提高了密封性能

雙重密封,金屬硬密封面保護(hù)軟密封材料不過(guò)載受損

Small friction between sealing surfaces

Fire and static proof structure

Wear resistance, corrosion resistance and long service life

Nylon valve flap, elastic seal, more reliable

Small working stroke, short opening and closing time

The gland nut is adjusted to improve the sealing performance

Double sealing, metal hard sealing surface protects soft sealing material from overload damage
