Abstract
The improved sealing part between flow channel and stopping body in a valve is one elastic non-metal ring with an annular lip. When the valve is shut, the pressure in the flow channel compresses the sealing surface of the annular lip to the stopping body tightly, and this can compensate the wear of the sealing part to make the valve no leakage.
Description
The present invention relates to a kind of valve sealing element, particularly valve flowing channel and valve by the valve sealing element between the body.
At present, in known various valves, valve flowing channel and the Sealing that ends between the body are elastic annular bodies, the Sealing of this structure in use, the sealing surface of the medium wearing and tearing Sealing in body and runner, the sealing surface of Sealing and form the gap between the body when valve is in closed condition makes valve closing sternly not cause leakage, has shortened the working life of valve.
The object of the present invention is to provide a kind of valve flowing channel and valve by the valve sealing element between the body, to overcome the deficiency of known technology.
The present invention is achieved in that a kind of valve flowing channel and valve by the valve sealing element between the body, and it comprises a nonmetal elastic annular body, and its improvements are to have an annular seal lip on the elastic annular body.
Valve sealing element of the present invention can be that sealing lip is curved surface with valve by the sealing surface that body contacts.
Valve sealing element of the present invention can be that sealing lip is the plane with valve by the sealing surface that body contacts.
Valve sealing element of the present invention can be that the elastic annular body is a garden staving.
Valve sealing element of the present invention can be that the elastic annular body is by a garden staving and the ring bodies that the garden ring body constitutes.
Valve sealing element of the present invention can be that the elastic annular body is a garden ring body.
A kind of valve flowing channel provided by the invention and valve are by the valve sealing element between the body, when valve is in closed condition, pressure in the valve flowing channel makes the sealing surface and the valve of the sealing lip of Sealing compress by body, valve does not leak, the valve sealing element of this structure can the wearing and tearing of compensating sealing surface in running, prolonged the working life of valve.

The invention will be further described in conjunction with the embodiments with reference to accompanying drawing.
Embodiment 1, Fig. 1 and Fig. 2 have provided valve flowing channel of the present invention and valve by a kind of concrete structure of valve sealing element between the body, and as shown in the figure, it comprises a nonmetal elastic annular body, have sealing lip 2 on the elastic annular body, playing ring bodies is a garden staving 1.Fig. 3 provides the sealing means of this valve sealing element in ball valve, and sealing lip 2 is curved surface with valve by the sealing surface that body 3 contacts.Sealing lip 2 forms ring-shaped cavity with the valve flowing channel end face, and the pressure when valve is in closed condition in the runner makes the sealing surface of sealing lip and valve compress by body, and valve does not leak, can the wearing and tearing of compensating sealing surface in running.Above-mentioned valve sealing element also is suitable for the sealing of stop valve and stopcock, column valve, butterfly valve and safety check and plate valve.
Embodiment 3, Fig. 6 has provided the sealing means of the another kind of structure of valve sealing element of the present invention in plate valve, as shown in the figure, the valve sealing element of this structure, its nonmetal elastic annular body is a garden ring body 7, have sealing lip 2 on the garden ring body 7, sealing lip 2 is the plane with valve by the sealing surface that body 8 contacts.Its sealing principle is identical with embodiment 1.Fig. 7 provided with Fig. 6 in the sealing means of the essentially identical valve sealing element of structure in butterfly valve and safety check, garden ring body 7 is different with angle and the Sealing among Fig. 6 of sealing lip 2, sealing lip is a curved surface with ending the sealing surface that body 9 contacts.Its sealing principle is identical with embodiment 1.The basic structure of the Sealing that Fig. 6 provides also is suitable for the sealing of other valve.
