Pneumatic knife switches use pneumatic valve characteristics and the note

pneumatic breaker pneumatic valve according to different made into non-rising stem and stem diameter two forms ( Non-rising stem DN to mm, rising stem DN - Mm, all round the dc channel design of sludge, BuKa resistance. Knife plate bottom into the blade shape processing of soft materials such as fiber, paper pulp, wood pulp has cut off function, at the same time has good opening and closing action. In the upper blade equipped with hard teflon wiper, can prevent the dust and scratch sexual material such as gravel into the stuffing box, can significantly improve the blade life. The pneumatic valve material selection of stainless steel, fine grinding and polishing processing can obtain the best sealing effect. Compact design, occupying small space, light weight, cheap, easy to install, wear-resisting prevent measures to perfect, easy maintenance, easy to use and long service life, and can choose which drives.
pneumatic breaker pneumatic valves, pneumatic knife gate valve pneumatic knife gate valve pneumatic type knife gate valve American standard matters needing attention in the product use and its characteristics: pneumatic type knife gate valve opening and closing is ram, ram movement direction perpendicular to the direction of flow and the pneumatic type knife gate valve can only be fully open and close, not to adjust and throttling. Sealing face has two gate, two of the most commonly used model of pneumatic valve gate sealing surface form a wedge, the wedge Angle vary with parameters of pneumatic valve, usually, pneumatic type wedge knife gate valve disc can be made into a whole, is called a rigid disc; Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, the pneumatic type damper is called elastic disc knife gate valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the pneumatic valve seat sealing surface pressure to ensure that the seal face seal, this is the seal. Most of the pneumatic type knife gate valve is sealed with mandatory, the pneumatic valve is closed, to rely on outside force forced the ram pressure to the pneumatic seat, to ensure the sealing surface sealing.
pneumatic breaker pneumatic control valve with pneumatic actuator pneumatic valve, pneumatic valve is opened and closed so as to realize a kind of pneumatic valve. It can be divided into fluctuation two parts, the upper part of pneumatic actuators, the lower part of pneumatic valve.
pneumatic breaker pneumatic valve has simple and compact structure, reasonable design, lightweight materials, sealing is reliable, flexible and convenient operation, small volume, smooth channel, small flow resistance, light weight, easy to install, easy to remove, etc, can be in work pressure. MPa - 。 MPa, the use of temperature - - ℃ cases, normal work. Pneumatic type knife gate valve gate with shear function, and can shave their seal adhesive on the surface of the object, automatically removing debris, stainless steel gate to prevent seal leakage caused by corrosion.
