進(jìn)口保溫閘閥德國洛克產(chǎn)品特點（工作原理，安裝須知）

一、進(jìn)口保溫閘閥產(chǎn)品描述：

德國《LOCKE》洛克進(jìn)口保溫閘閥(Insulation gate valve)主要用于石油、化工、冶金、制藥等各類系統(tǒng)中，該閥門的夾套焊裝于閥門的兩法蘭之間，閥門的側(cè)面、底部設(shè)置有夾套的連接口，夾套中可自由地流過蒸汽或其它熱的保溫介質(zhì)，確保粘稠介質(zhì)可順暢地流過閥門。

Locke imported insulation gate valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems. The valve's jacket is welded between the two flanges of the valve. The side and bottom of the valve are equipped with the connection port of the jacket. The jacket can freely flow through the steam or other hot insulation medium to ensure that the viscous medium can flow smoothly through the valve.

三、進(jìn)口保溫閘閥結(jié)構(gòu)優(yōu)點： 

1、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。

2、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(yùn)動方向均與介質(zhì)流動方向相垂直。

3、高度大，啟閉時間長。閘板的啟閉行程較大，降是通過螺桿進(jìn)行的。

4、水錘現(xiàn)象不易產(chǎn)生。原因是關(guān)閉時間長。

5、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。

6、結(jié)構(gòu)長度(系殼體兩連接端面之間的距離)較小。

7、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。

8、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。

1. The flow resistance is small. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.

2. It is easier to open and close. Compared with the stop valve, the movement direction of the ram is perpendicular to the flow direction of the medium whether it is open or closed.

3. High height, long opening and closing time. The opening and closing stroke of the ram is large, and the lowering is carried out by the screw.

4. Water hammer is not easy to occur. The reason is that it takes a long time to close.

5. The medium can flow in any direction on both sides, which is easy to install. Both sides of gate valve channel are symmetrical.

6. The length of the structure (the distance between the two connecting ends of the system housing) is small.

7. 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 rub and slide against each other, which is easy to produce abrasion under the action of medium pressure, affect the sealing performance and shorten the service life.

8. The price is more expensive. There are many contact sealing surfaces and complicated processing, especially the sealing surface on the ram seat is not easy to process, and there are many parts. The utility model has the advantages of simple shape, short structure length, good manufacturing technology and wide application range.
