進口保溫閘閥工作原理：

進口保溫閘閥的流動阻力小。閥體內(nèi)部介質(zhì)通道是直通的，介質(zhì)成直線流動，流動阻力小。啟閉時較省力。是與截止閥相比而言，因為無論是開或閉，閘板運動方向均與介質(zhì)流動方 向相垂直。高度大，啟閉時間長。閘板的啟閉行程較大，降是通過螺桿進行的。水錘現(xiàn)象不易產(chǎn)生。原因是關(guān)閉時間長。介質(zhì)可向兩側(cè)任意方向流動，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，閘板與閥座兩個密封面相互摩擦滑動，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 insulated gate valve:
The flow resistance of the imported insulated gate valve is small. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small. It is easy to open and close. Compared with the stop valve, because whether it is open or closed, the movement direction of the ram is perpendicular to the flow direction of the medium. High height, long opening and closing time. The opening and closing stroke of the ram is large, and the lowering is carried out through the screw. Water hammer is not easy to occur. The reason is the long closing time. The medium can flow to both sides in any direction, easy to install. Both sides of gate valve passage are symmetrical. The structure length (the distance between the two connecting ends of the shell) is small. The sealing surface is easy to wear, which affects the service life. When opening and closing, the two sealing surfaces of the gate and the valve seat slide against each other, which will easily cause abrasion under the action of medium pressure, affect the sealing performance and shorten the service life. The price is more expensive. There are many contact sealing surfaces, the processing is more complex, especially the sealing surface on the ram seat is not easy to process, and there are many parts. It has the advantages of simple shape, short structure length, good manufacturability and wide application range. The valve features compact structure, good rigidity, smooth passage, small flow resistance, stainless steel and cemented carbide sealing surface, long service life, PTFE packing, reliable sealing, light and flexible operation.

Introduction of imported insulated gate valve products:
Germany Locke "de Locke" imported insulation gate valve is welded with a jacket between the two flanges. The side and bottom of the valve are equipped with a jacket connection port. The jacket is used for circulating steam, heat transfer oil or other insulation and cooling medium to ensure that the medium flows smoothly through the valve or reaches the required temperature. This product is mainly used in petroleum, chemical, metallurgical and petrochemical industries And other types of easy crystallization, high viscosity medium system
