As mentioned above, there are electric plate gate valves in the classification of electric gate valves. The following is the detailed information of this product:
The electric plate gate valve is a sliding valve with parallel gate closing parts. The closing member may be a single gate or a double gate with a supporting mechanism. The pressure force of the gate against the seat is controlled by the medium pressure acting on the floating gate or floating seat. If it is a double gate plate gate valve, the supporting mechanism seen by the two gate plates can supplement this compression force.
1. The seat adopts o-ring seal and floating seat structure with pre-tightening force. The electric globe valve makes the inlet and outlet of the electric plate gate valve sealed in two directions. Moreover, the opening and closing moment of this structure is only 1/2 of that of ordinary valves, which can easily open and close valves
2. When fully open, the channel is smooth as a straight line, with minimal flow resistance coefficient and no pressure loss. The pipeline can be cleaned by passing the bulb
3. The packing structure with self-sealing ability is adopted, and the pneumatic ball valve does not need constant adjustment. It is very light to open and close, and the sealing performance is reliable. The defects of common valve packing are solved
4. When closing, the electric plate gate valve can automatically discharge the high pressure in the inner cavity to ensure safe operation
5. Fully enclosed structure, good protection performance, able to meet all weather requirements
(1) yoke sleeve -- aluminum bronze yoke sleeve is equipped with needle thrust bearings to minimize operating torque.
(2) electric gate valve stem -- thread length up to bracket; Pin and spot welding; It's stable.
(3) pressure seal - simple structure, with segmented buckle ring and silver-plated low carbon steel gasket to help remove and realize the best bonnet seal.
(4) seat ring -- welded seat ring is perpendicular to the flow passage and easy to maintain.
(5) actuators - these valves can be equipped with electric, hydraulic or pneumatic actuators. Standard manual handwheel below DN300, oblique gear operating mechanism above DN350.
(6) yoke - the fully fabricated yoke is easy to maintain and install the actuator through seismic testing.
(7) pressure cover -- two pieces, self-adjusting pressure cover to avoid being ejected.
(8) integral backseat -- hard surface, with the longest service life.
(9) disc - spring loaded disc can adjust itself to reduce the torque requirement of the actuator.
(10) integral stop -- integral cast bracket stop device, positioning the assembled bracket disc, making the seat more stable and reliable
The above information is expected to help you better understand the electric plate gate valve products.
