Description
Technical field
The utility model relates to a kind of hand stop valve more particularly to a kind of hand stop valves with long service life.
Background technique
Shut-off valve, also known as pipe valve are a kind of valves for being usually used in playing the medium in pipeline cutting and throttling.Shut-off valve by
The components such as valve seat, valve rod composition, further includes the opening and closing element for having a stopper: flap, flap makees straight line fortune along the center line of valve seat
It is dynamic.Shut-off valve relies on the pressure of valve thick stick, i.e. valve rod makes valve clack sealing surface and valve by applying pressure to flap in the axial direction
Seat sealing surface fits closely, and realizes cutting, throttling to medium.And the movement of the handle of hand stop valve, exactly driving stem
Mechanism.
However in general figure is bigger for the handle on hand stop valve, weight is also larger.Manual shutoff on the market
The moiety by weight part of the handle of valve undertakes by protruding into valve rod therein, not only built on the sand and is very easy to lead to valve rod outer wall
Upper thread abrasion.On the one hand the screw thread of abrasion can not go up and down valve rod by assist handle again, on the other hand can not also undertake handle again
Weight has just be easy to cause the damage of shut-off valve over time.In addition to this, high flow rate medium fluid rushes medium runner
It hits, also will affect the use of shut-off valve, the service life of shut-off valve is caused to shorten.
