Description
Technical field
The utility model relates to a kind of dish valve, is meant that especially a kind of nothing friction opens and closes the dish valve.
Background technique
Traditional dish valve is to utilize rotary valve shaft drive valve plate (door-plate) to rotate 90 ° of unlatchings of finishing valve to move and cut out, the shortcoming that exists is: valve plate is in rotating process, because of being in contact condition between valve plate and the valve body, valve plate is when valve body rotates, need overcome bigger frictional force, cause the sealing pair wearing and tearing on the valve plate easily, valve seal is not sternly leaked, influence the working life of valve.
The model utility content
The purpose of this utility model is to provide a kind of and opens and closes flexibly, nothing is worn and torn, a kind of nothing of long service life rubs opens and closes the dish valve.
The purpose of this utility model is achieved in that a kind of nothing friction opens and closes the dish valve, comprise valve body, one to two valve plate, valve shaft and handle, valve shaft runs through valve body and also and between the valve body is dynamically connected, handle is fixed on the outer valve shaft of valve body, valve plate is arranged on the interior valve shaft of valve body, contact seal between valve plate and the valve body, wherein: be provided with pressure cylinder between described valve shaft and the valve plate, this pressure cylinder is made up of cylinder body and piston rod, cylinder body is fixedlyed connected with valve shaft, valve plate is fixedlyed connected with piston rod, is provided with thrust spring in the cylinder body periphery; Valve shaft end outside valve body is provided with compression pump, is provided with channel connection pressure cylinder and compression pump in valve shaft, and compression pump is provided with pressure-relief valve.
Compression pump described in the utility model is to adopt manually or electric hydraulic pump is good.
After the utility model adopts said structure, when valve opening and closing, can utilize compression pump to make between the valve plate of valve and the valve body separates earlier, and then handle with sleeve, thereby when rotating and the friction between the valve body by eliminating valve plate, avoid the wearing and tearing of valve plate sealing pair effectively, guarantee the sealability of valve, prolong the working life of valve.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
