Abstract
The utility model discloses a leak-free corrugated balance plunger valve which relates to a valve, in particular to a plunger valve. The leak-free corrugated balance plunger valve comprises a valve body (1), a valve base (2), a plunger (3), a valve rod (6) and bellows (7). The valve base (2) is arranged in the valve body (1), and the bellows (7) are sleeved on the valve rod (6). The lower end of the valve rod (6) is connected with the plunger (3) which is matched with a cylindrical hole of the valve base (2). The leak-free corrugated balance plunger valve is characterized in that the leak-free corrugated balance plunger valve also comprises a sealing cover (4) arranged on the inner wall of the cylindrical hole of the valve base (2). The plunger (3) is arranged in the sealing cover (4). The leak-free corrugated balance plunger valve solves the problem that liquid is leaked caused by infirm sealing of the traditional like product.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of plunger 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 plunger 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 ripple balance plunger 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 ripple balance plunger valve, comprise valve body 1, valve seat 2, plunger 3, valve rod 6 and bellows 7, valve seat 2 is arranged at valve body 1 inside, is set with bellows 7 on the valve rod 6, valve rod 6 lower ends connect plunger 3, and plunger 3 matches with the cylindrical hole of valve seat 2; Also comprise stuffing box gland 4, on the inwall of the cylindrical hole of valve seat 2 stuffing box gland 4 is arranged, plunger 3 is provided with stuffing box gland 4 inside.
Nothing of the present utility model is leaked ripple balance plunger valve, owing to increase stuffing box gland is arranged, so favorable sealing property, and stuffing box gland is made with wear-resisting rubber, therefore has long service life, the advantage of favorable sealing property.Nothing of the present utility model is leaked ripple balance plunger valve and is suitable for using on the liquid transmission pipeline that sewage etc. contains the grains of sand.
