PZ73H series Manual clamping type knife gate valve ，廣泛應(yīng)用于造紙

、石化、礦山

、排水

、食品等行業(yè)。">The knife type gate has a good shearing, the most suitable fluid in the slurry, powder granules, fibers and other difficult to control, widely used in papermaking, petrochemical, mining, drainage, food and other industries. ，并且可依據(jù)現(xiàn)場控制需求

，配備電動或氣動執(zhí)行器，實(shí)現(xiàn)閥門的自動化操作

。">Knife type valve with a variety of seat options, and can be controlled according to site requirements, equipped with electric or pneumatic actuators, valve automation.
、應(yīng)用范圍：">Second, the scope of application:
PZ73H series Manual clamping type knife gate valve 、纖維等難以控制的流體

，廣泛應(yīng)用于造紙、石化

、礦山

、排水、食品等行業(yè)

。">The suitable fluid in the slurry, powder granules, fibers and other difficult to control, widely used in papermaking, petrochemical, mining, drainage, food and other industries.
、結(jié)構(gòu)特點(diǎn)：">Three, structural characteristics:
PZ73H series Manual clamping type knife gate valve ，閘閥只能作全開和全關(guān)

，不能作調(diào)節(jié)和節(jié)流。">Is the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.
，***常用的模式閘板閥的兩個(gè)密封面形成楔形

、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

。">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 gate.
，即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封

，這就是自密封。">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. ，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。">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.
