Seat is arranged in the connecting pin of valve plate and valve seat, and the lower end of the valve body, which is equipped with for valve seat to be pressed in, to be cooperated on valve body with valve plate
Valve seat pressing ring, the valve body spray anti-corrosion layer, the connecting hole between the valve plate and valve rod on the contact sealing surface with valve seat
To be socketed with limit stop ring at the bottom end of hexagonal shape, the valve rod.
As an improvement, the upper end of the valve rod is equipped with the interface for being intended to extraneous actuator connection, the interface is to meet the world
The interface of standard interface size, can be direct-connected with actuator.
As an improvement, being equipped with check ring between the valve body and valve plate.
As an improvement, the valve rod outside and filler lower part be equipped with filler assembly.
As an improvement, the anti-corrosion layer is powder of stainless steel.
The utility model has the following beneficial effects:
The utility model is compact structure and easy to use, is designed to comply with international standard interface ruler with actuator coupling part
Very little, guarantee is accurately connect with actuator, does not have to transition bracket, keeps assembly quicker.Valve body and valve seat contact seal face spray
Corrosion-resistant stainless steel powder solves sealing surface etching problem.Valve plate is designed to that hexagon connects with valve shaft connecting hole, solves pin
Axis connection bring valve shaft strength reduction problem, makes assembling speed rapid and convenient, lacked compared with existing product a bracket and
4-8 bolt and nut, while processing and assembly time are saved, improve production efficiency.
