Pneumatic single seat control valve is to compress the empty
CLICLS：573
Pneumatic gate valve of electric actuator solves existing problems such as high labor intensity and troublesome operation. Its characteristics are: Feed tube is set in the upper part of the body, on the other side set fixed gate valve plate and activities, jiangyin heaven products science activity ram through the pin shaft and on the guide rail sliding boards are linked together, the skateboard end through the pin shaft connected to the connecting rod, the other end of the connecting rod through the fittings are connected to the cylinder piston rod, cylinder is fixed by bolts connecting rod set installed on the valve body end; The lower part of the valve body is provided with a center and a hopper.
Has the advantages of reasonable structure, convenient operation, high efficiency, can be widely used in diameter less than 80mm granular material and powder material discharge, and can be manually or automatically controlled, pneumatic ball valve ball is elastic. Ball and valve seat sealing ring are made of metal materials, sealing specific pressure is very large, relying on the pressure of the medium itself has not reached the requirements of sealing, external force must be applied. This valve is suitable for high temperature and high pressure medium, elastic sphere is in the lower end of the inner wall of the sphere open an elastic groove, and obtain elasticity. When closing the aisle, use the stem wedge to open the ball and seal the seat.
Loosen the wedge before turning the ball, the ball will then return to its original shape, so that there is a small gap between the ball and the seat, wide side butterfly valve reduces sealing surface friction and operating torque.
Electric ball valve use is a right Angle rotary structure, it is used with the valve positioner, can achieve proportional adjustment; V-type spool is most suitable for various adjustment occasions, with large rated flow coefficient, adjustable ratio, good sealing effect, zero sensitive adjustment performance, small volume, vertical lying installation. Suitable for controlling gas, steam, liquid and other media. It is characterized by a right-angle rotary structure, composed of v-shaped valve body, pneumatic actuator, positioner and other accessories; There is a natural flow characteristic of approximately equal hundred ratio; Double bearing structure, small starting torque, with excellent sensitivity and induction speed; Super shearing ability.
