Electro hydraulic knife gate valve

PZ273H series Electro hydraulic knife gate valve Is a gate opening and closing parts, RAM direction …

Description：

、簡(jiǎn)介說明：" style="background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">A brief introduction:
PZ273H series Electro hydraulic knife gate valve ，閘板的運(yùn)動(dòng)方向與流體方向相垂直，手動(dòng)刀型閘閥只能作全開和全關(guān),不能作調(diào)節(jié)和節(jié)流。">Is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, the manual knife gate valve can be fully open and fully closed, can not be adjusted and the throttle. 、楔形角隨閥門參數(shù)而異,通常為50,楔式刀型閘閥的閘板可以做成一個(gè)整體，叫做剛性閘板

；也可以做成能產(chǎn)生微量變形的閘板,以改善其工藝性,彌補(bǔ)密封面角度在加工過程中產(chǎn)生的偏差,這種閘板叫做彈性閘板刀型閘閥關(guān)閉時(shí),密封面可以只依靠介質(zhì)壓力來(lái)密封,即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來(lái)保證密封面的密封,這就是自密封.大部分刀型閘閥是采用強(qiáng)制密封的,即閥門關(guān)閉時(shí)

，要依靠外力強(qiáng)行將閘板壓向閥座,以保證密封面的密封性本類閥門在管道中一般應(yīng)當(dāng)水平安裝。">There are two gate sealing surface, the most common mode of gate valve sealing surface to form two wedge, the wedge angle varies with the valve parameters, usually 50, wedge type knife gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of the deviation, make up the sealing surface angle in the process, the gate is called the flexible knife gate valve is closed, the sealing surface can only rely on media pressure to seal, that media pressure will depend on the sealing surface of the ram pressure to the other side of the seat to ensure the sealing surface of the seal, which is self sealing. Most of the knife gate valve is sealed by force, that the valve is closed, to rely on external pressure to force the gate to the seat, to ensure the sealing surface of the seal of the valve in the pipe shall be installed horizontally.
、測(cè)量原理：">Two, measurement principle:
PZ273H series Electro hydraulic knife gate valve 、設(shè)計(jì)合理、輕型節(jié)材,密封可靠
