The manual rotary valve of described 3-position 4-way, described valve gap lower surface are equipped with the seal ring with valve gap lower surface and base upper surface sealing.
The manual rotary valve of described 3-position 4-way, also be equipped with on the described valve gap one the sealing described rotating shaft O-ring seals.
The manual rotary valve of described 3-position 4-way is bolted and fixed with the one handle ball on the described handle.
The manual rotary valve of described 3-position 4-way is equipped with O shape circle on the outer peripheral surface of described seal cartridge.
The manual rotary valve of described 3-position 4-way, described base is connected by screw with valve gap.
The utility model beneficial effect is:
By the such structural design of the utility model, make its sealing improve greatly, and commutation is steady, impact is little, response is fast, maintenance and installation be the convenience of ten minutes all.Especially valve plate adopts the material of pottery, has further strengthened wear resistance and heat resistance, makes that whole rotary valve sealability is better, more difficult gas leakage.
