Abstract
The utility model provides a small-caliber valve easy to seal. The small-caliber valve easy to seal is characterized in that a valve pedestal prepared from soft material is extruded on a valve body by a screwed joint, and the valve pedestal forms plane sealing with a valve clack. According to the structure, the valve is easy to seal, to process and to manufacture, the process is simple, and the maintenance is convenient.
Description
Technical field
The utility model relates to a kind of stop valve that is used to switch on or off the pipeline medium, particularly a kind of small-bore stop valve of easy realization sealing.
Background technique
The small-bore stop valve that uses at present generally adopts the metal conical surface seal, because valve seat and flap receive machining accuracy, hardness and malalignment, friction etc. to influence conical surface seal ubiquity leakage problem.
The model utility content
The purpose of the utility model is the small-bore stop valve that a kind of easy realization sealing will be provided.
The utility model is achieved in that the valve seat soft material made with inipple upwards is squeezed on the valve body from the lower end of valve body; The end face of flap is pressed on the valve seat from the top down, and the distortion that the sealing of valve produces after through the sealing surface of seat pressurized realizes.
The utility model adopts valve seat that inipple makes soft material upwards to be squeezed on the valve body from the lower end of valve body, forms plane sealing with flap, and valve is sealed easily, and make the manufacturing process of valve simple, easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing the structural principle of the utility model is done to specify.
Accompanying drawing is the structure principle chart of the utility model.
Embodiment
With reference to accompanying drawing, the utility model is by inipple (1), valve seat (2), form with valve rod (3), valve body (4), seal washer (5), gland (6), gland nut (7), the handle (8) of flap one.
With inipple (1) lower end of valve seat (2) from valve body (4) upwards is squeezed on the valve body (4); Downwards end face is pressed on the valve seat (2) with the valve rod (3) of flap one top from valve body (4); Produce distortion behind the sealing surface pressurized of valve seat (2), the distortion that produces behind the sealing surface pressurized of the sealing of valve through valve seat (2) realizes.
Claims (1)
1. small-bore stop valve of realizing easily sealing is characterized in that valve seat that this stop valve makes soft material with inipple upwards is squeezed on the valve body from the lower end of valve body, forms plane sealing with flap.
