進(jìn)口保溫閘閥工作原理：

進(jìn)口保溫閘閥的流動(dòng)阻力小。閥體內(nèi)部介質(zhì)通道是直通的，介質(zhì)成直線流動(dòng)，流動(dòng)阻力小。啟閉時(shí)較省力。是與截止閥相比而言，因?yàn)闊o論是開或閉，閘板運(yùn)動(dòng)方向均與介質(zhì)流動(dòng)方 向相垂直。高度大，啟閉時(shí)間長。閘板的啟閉行程較大，降是通過螺桿進(jìn)行的。水錘現(xiàn)象不易產(chǎn)生。原因是關(guān)閉時(shí)間長。介質(zhì)可向兩側(cè)任意方向流動(dòng)，易于安裝。閘閥通道兩側(cè)是對稱的。結(jié)構(gòu)長度(系殼體兩連接端面之間的距離)較小。密封面易磨損，影響使用壽命。啟閉時(shí)，閘板與閥座兩個(gè)密封面相互摩擦滑動(dòng)，要介質(zhì)壓力作用下易產(chǎn)生擦傷磨損，影響密封性能，縮短使用壽命。價(jià)格較貴。接觸密封面較多，加工較復(fù)雜，特別是閘板座上的密封面不易加工，而且零件較多。形體簡單 , 結(jié)構(gòu)長度短，制造工藝性好，適用范圍廣。結(jié)構(gòu)緊湊，閥門剛性好，通道流暢，流阻數(shù)小，密封面采用不銹鋼和硬質(zhì)合金，使用壽命長，采用PTFE填料．密封可靠．操作輕便靈活。

Working principle of imported thermal insulation gate valve:
The flow resistance of the inlet thermal insulation gate valve is small. The medium passage inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small. It is more labor-saving when opening and closing. Compared with the stop valve, the gate movement direction is vertical to the direction of medium flow, whether it is open or closed. High height, long opening and closing time. The opening and closing stroke of ram is large, and the lowering is carried out by screw. Water hammer is not easy to produce. The reason is that the shutdown time is long. The medium can flow in any direction on both sides, and it is easy to install. The gate valve channel is symmetrical on both sides. The length of the structure (the distance between the two connecting ends of the shell) is small. The sealing surface is easy to wear and affect the service life. When opening and closing, the two sealing surfaces of ram and valve seat are friction and sliding, which will easily cause abrasion under medium pressure, which will affect sealing performance and shorten service life. The price is higher. The contact sealing surface is more, and the processing is more complex, especially the sealing surface on the ram seat is not easy to process, and there are many parts. The structure is simple, the structure length is short, the manufacturing technology is good, and the application range is wide. The valve has compact structure, good rigidity, smooth passage, small flow resistance, stainless steel and cemented carbide on the sealing surface, long service life, PTFE packing. Reliable sealing and flexible operation.
                                                                               

進(jìn)口保溫閘閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進(jìn)口保溫閘閥在兩法蘭之間焊裝上夾套，閥門的側(cè)面、底部設(shè)置有夾套的連接口，夾套中通過循環(huán)蒸汽、導(dǎo)熱油或其它保溫保冷的介質(zhì)，確保介質(zhì)順暢地流過閥門或達(dá)到所需要的溫度，本產(chǎn)品主要用于石油、化工、冶金、制 等各類易結(jié)晶、粘稠度較高介質(zhì)的系統(tǒng)中.

Introduction to imported thermal insulation gate valve products:
The imported thermal insulation gate valve of de lock of Locke is welded and installed with a jacket between two flanges. The side and bottom of the valve are equipped with a connecting port with a jacket. The jacket ensures the medium flows smoothly through the valve or reaches the required temperature through circulating steam, heat transfer oil or other medium for heat preservation and cooling. This product is mainly used for petroleum, chemical industry, metallurgy and manufacturing In the system of various easy crystallization and high viscosity medium
