Position seating eliminates stress and potential binding due to thermal expansion of the stem 定位閥座消除了由于閥桿的熱膨脹導(dǎo)致的應(yīng)力和可能的彎曲。
Internal stops provide positive over travel protection for power actuated valves and act as a reference to position the discs in the open and closed positions 內(nèi)置的止動(dòng)裝置為動(dòng)力執(zhí)行機(jī)構(gòu)提供行程保護(hù),并且作為參考坐標(biāo)在開(kāi)啟和關(guān)閉位置定位閥瓣。
Gate valves are offered in two designs : parallel disc and flexible wedge . parallel disc are position seated ; flexible wedge are torque seated when closing 我們提供的閘閥的結(jié)構(gòu)形式具有兩種:平行閥瓣和彈性楔形閘板。平行閥瓣為定位閥座密封;彈性楔形閘板在關(guān)閉時(shí)則是扭矩閥座密封。
