Abstract
The utility model discloses a stop valve. The stop valve includes a valve body, wherein a water inlet and a water outlet are formed at the left end and the right end of the valve body respectively, a chamber is formed inside the valve body, a service port is formed on the side wall of the chamber and covered by a sealing cover, a valve clack seat is arranged at the bottom of the chamber and separates the water inlet from the water outlet, a water outlet hole is formed at the upper end of the valve clack seat, a valve cap is connected with the upper end of the valve body, a valve rod is rotationally mounted in the valve cap, and a valve clack is fixedly mounted at the lower end of the valve rod and hermetically connected with the water outlet hole of the valve clack seat. The stop valve has the advantages of stable structure, high leak tightness and long service life.
Description
Technical field
The utility model relates to a kind of stop valve.
Background technique
Stop valve belongs to forced seal formula valve, so when valve closing, must exert pressure to flap, does not leak with forced seal face.When medium enters valve by the flap below, the required resistance that overcomes of steering force is the frictional force and the thrust that is produced by the pressure of medium of valve rod and filler, and the power that the force rate of closing valve is opened valve is large, so it is large that the diameter of valve rod is wanted, otherwise the fault of valve rod bending can occur.In recent years, after occurring from self-packing valve, the MEDIA FLOW of stop valve enters valve pocket to just changing by the flap top, and at this moment under the pressure medium effect, the power of closing valve is little, and it is large to open the power of valve, and the diameter of valve rod can correspondingly reduce.
The model utility content
The utility model provides a kind of structural stability, good airproof performance, the stop valve of looking working life.
The utility model technical solution problem provides following scheme:
A kind of stop valve, comprise valve body, it is characterized in that: the left and right two ends of described valve body are respectively equipped with water intake, water outlet, the inside of described valve body has chamber, the sidewall of described chamber is provided with access hole, described access hole is stamped sealing cover, the bottom of described chamber has the flap seat, described flap seat separates water intake and water outlet, the upper end of described flap seat is provided with osculum, and the upper end of described valve body is connected with valve gap, is rotatablely equipped with valve rod in the described valve gap, the lower end of described valve rod is installed with flap, and described flap and flap seat osculum are tightly connected.
Be installed with seal ring on the sidewall of described flap.
The utility model stop valve is offered access hole at the sidewall of the chamber of valve inner, and is long-time when no when valve like this, education mouthful can be opened, and emits the moisture that the valve body inner product is held, and prevents that valve body from getting rusty.
Description of drawings
Fig. 1 is structural representation of the present utility model.
