進(jìn)口焊接閘閥產(chǎn)品優(yōu)點(diǎn)-德國洛克

進(jìn)口焊接閘閥結(jié)構(gòu)特點(diǎn):

重量輕，本體采用球黑鑄鐵制成，重量較傳統(tǒng)閘閥重量減輕約20%~30%，安裝維修方便。平底式閘座：傳統(tǒng)的閘閥往往在通水洗管后即因外物諸如石頭，木塊、水泥、鐵屑、雜物等淤積于閥底凹槽內(nèi)，容易造成無法關(guān)閉緊密而形成漏水現(xiàn)象，彈性座封閘閥底部采用與水管機(jī)同的平底設(shè)計(jì)，不易造成雜物淤積，使流體暢通無阻。整體包膠：閘板采用高品質(zhì)的橡膠進(jìn)行整體內(nèi)、外包膠，歐洲*的橡膠硫化技術(shù)使得硫化后的閘板能夠保證 的幾何尺寸，且橡膠與球墨鑄閘板接著牢靠，不易脫落及彈性記憶佳。水精鑄閥體：閥體采用精密鑄造， 的幾何尺寸使得閥體內(nèi)部無需任何精加工即可保證閥門的密封性。

進(jìn)口焊接閘閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進(jìn)口焊接閘閥主要適用于公稱壓力PN10.0-40.0Mpa,工作溫度≤580℃的石油、化工、水力、火力電站各種系統(tǒng)的管路上,切斷或接通管路介質(zhì)。適用介質(zhì)為水、油品、蒸汽、及某些fu蝕性液體等。操作方式有手動(dòng)、齒輪傳動(dòng)、電動(dòng)等。

進(jìn)口焊接閘閥工作原理：

閘閥是只能做全開或者全關(guān)的，不能作為調(diào)節(jié)流量的閥門使用。他的工作原理就是閘閥隨閘桿一起作上升或者下降做直線運(yùn)動(dòng)，閥桿上有梯形螺紋，通過閥門頂端的螺母以及閥體上的導(dǎo)槽，來實(shí)現(xiàn)閥桿的上下運(yùn)動(dòng)，閥桿帶動(dòng)閘板運(yùn)動(dòng)。閘板的運(yùn)動(dòng)方向與管道流體介質(zhì)方向是垂直的。

Working principle of imported welding gate valve:
Gate valve can only be fully open or fully closed, and cannot be used as a valve regulating flow. His working principle is that gate valve moves in a straight line with the gate rod rising or falling together. The valve stem has trapezoidal thread. Through the nut at the top of the valve and the guide groove on the valve body, the valve stem moves up and down, and the valve rod drives the ram to move. The direction of ram movement is vertical to the direction of pipeline fluid medium.

進(jìn)口焊接閘閥安裝要點(diǎn)：

手輪、手柄及傳動(dòng)機(jī)構(gòu)均不允許作起吊用，并嚴(yán)禁碰撞。雙閘板閘閥應(yīng)垂直安裝（即閥桿處于垂直位置 , 手輪在頂部 )。帶有旁通閥的閘閥在開啟前應(yīng)先打開旁通閥（以平衡進(jìn)出口的壓差及減小開啟力 )。帶傳動(dòng)機(jī)構(gòu)的閘閥，按產(chǎn)品使用說明書的規(guī)定安裝。如果閥門經(jīng)常開關(guān)使用 , 每月至少潤滑一次。

Installation points of imported welding gate valve:
Hand wheel, handle and transmission mechanism are not allowed to be used for lifting and collision is strictly prohibited. Double gate valves shall be installed vertically (i.e. stem in vertical position and handwheel at top). The gate valve with bypass valve should be opened before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force). Gate valve with transmission mechanism shall be installed according to the product instruction. If the valve is used frequently, lubricate at least once a month.
