manual knife gate valve of penetrade

又稱手動(dòng)插板閥，它是一種閘板與閥座始終緊密接觸密封的閥門，其原理是閘板上開有一個(gè)通徑大小的圓口，通過閘板啟閉使得閘板上圓口跟通徑做*脫離和相吻合的動(dòng)作。此閥門的優(yōu)點(diǎn)在于閥體通徑無凹槽，介質(zhì)不會(huì)卡阻堵塞，并且具有全通徑流通特性，適合粉體顆粒介質(zhì)的管道中使用。其密封結(jié)構(gòu)可以分軟密封、硬密封結(jié)構(gòu)。穿透式刀閘閥是具有精密構(gòu)造，工藝性好，結(jié)構(gòu)緊湊等特點(diǎn)，密封閥座為活動(dòng)結(jié)構(gòu)設(shè)計(jì)，有防磨損和自動(dòng)補(bǔ)償功能，因而壽命更長(zhǎng)。在關(guān)閉和開啟過程中閥座跟閘板一直緊貼運(yùn)動(dòng)，使得閥門啟閉力穩(wěn)定，并且具有切斷介質(zhì)等特點(diǎn)。配置手輪可以很直接操作手輪來啟閉閥門。

Manual penetration knife gate valve also can be named manual flashboard valves which gate closely contacts with the seat , Principle is that there is a diameter size of circular port in the gate ,opening and closing gate makes circular port takes off and consistent action with diameter .

The advantages of this valve are : body's diameter without grooves, the medium does not plug the card blocking, full-diameter flow characteristics, suitable for powder using in the pipeline. The sealing structure can be divided into soft-seal and hard seal structure. Penetrable Knife Gate Valve is a sophisticated structure, good technology , compact structure, etc, activities of structural design of sealing seat , anti-wear and automatic compensation function and long age. Gate keeps closely movement with gate when opening and closing ,makes valve open and close stability and cuts off the media, and so on. Hand wheel can directly operate wheel to open and close the valve.
