Abstract
The utility model discloses a leak-tight corrugated piston valve, which relates to a valve, in particular to a piston valve. The piston valve comprises a valve body (1), a valve seat (2), a piston (3), a valve rod (6), a corrugated pipe (7), a sealing sleeve (4) and a sealing washer (5), wherein the valve seat (2) is arranged in the valve body (1); the corrugated pipe (7) is sleeved on the valve rod (6); the lower end of the valve rod (6) is connected with the piston (3); the piston (3) is matched with the valve seat (2); the upper part of the valve seat (2) is provided with the sealing sleeve (4); the sealing sleeve (4) is fixedly connected with the valve seat (2) through screws; the piston (3) has a bowl-shaped structure with a cambered lower end and is arranged in the sealing sleeve (4); and the upper end of the piston (3) is provided with the sealing washer (5). Through the leak-tight corrugated piston valve, the problems of untight sealing and liquid leakage of the conventional similar products are solved.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of piston valve.
Background technique
There is the shortcoming of sealing difference in existing valve, especially after long-time the use, owing to have the grains of sand in the sewage, can cause between valve seat and the piston cut to occur in the effluent discharge pipeline, causes poorly sealedly, the problem of leak of liquid occurs.
The model utility content
The purpose of this utility model provides a kind of nothing and leaks the ripple piston valve, and it is poorly sealed that the utility model has solved existing like product, the problem of leak of liquid occurs.
Nothing of the present utility model is leaked the ripple piston valve, comprises valve body 1, valve seat 2, piston 3, valve rod 6 and bellows 7, and valve seat 2 is arranged at valve body 1 inside, is set with bellows 7 on the valve rod 6, and valve rod 6 lower ends connect piston 3, and piston 3 cooperates with valve seat 2; Also comprise stuffing box gland 4 and seal washer 5, be provided with stuffing box gland 4 on valve seat 2 tops, stuffing box gland 4 is fixedlyed connected with valve seat 2 by screw, and described piston 3 is the bowl structure of lower end circular arc, piston 3 is provided with stuffing box gland 4 inside, and piston 3 upper ends are provided with seal washer 5.
Nothing of the present utility model is leaked the ripple piston valve, owing to increase stuffing box gland and seal ring is arranged, so favorable sealing property, and stuffing box gland and seal ring adopt wear-resisting rubber to make, and therefore has long service life, the advantage of favorable sealing property.Nothing of the present utility model is leaked the ripple piston valve and is suitable for using on the liquid transmission pipeline that sewage etc. contains the grains of sand.
