Abstract
The utility model discloses a valve seat of metal hard sealed ball valves. The valve seat is arranged between a ball body and a valve body and is of a circle structure, wherein one side of the valve seat is a valve body contact surface and the other side of the valve seat is a valve body sealing surface and attached to the ball body, and a wave spring, a press ring and a sealing pad are arranged on the valve body contact surface. The valve seat of the metal hard sealed ball valves is characterized in that the wave spring of the valve seat is a bidirectional wave spring and arranged between the press ring and the valve body. The valve seat of the metal hard sealed ball valves is compact and reasonable in structure. Compared with an existing valve seat, the valve seat of the metal hard sealed ball valves is flexible to open and close, few in accessories, and easy to assemble.
Description
Technical field
The utility model relates to a kind of metal hard-sealing ball valve valve seat.
Background technique
Existing metal hard-sealing ball valve: adopt two group springs, one group provides thrust to valve body, and one group provides thrust to seal ring.The many complex structures of parts, assembling difficulty is large, and cost of production is high.
The model utility content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of metal hard-sealing ball valve valve seat is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
The utility model discloses a kind of metal hard-sealing ball valve valve seat, valve seat is arranged between spheroid and the valve body, structure ringwise, and a side is the valve body surface of contact, opposite side is that valve body sealing surface and spheroid are fitted, and described valve body surface of contact is provided with ripple spring, pressure ring, sealing gasket.
Described valve seat ripple spring is two-way ripple spring, is arranged between described pressure ring, the valve body.
Described pressure ring; One end contacts with described ripple spring, and the other end contacts with described sealing gasket.
The beneficial effects of the utility model are:
The utility model compact structure, rationally; Compare with existing valve seat, open and close flexible operation, accessory is few, and assembling is simple.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 the utility model annexation partial cutaway schematic;
Number in the figure explanation: 1, valve body, 2, spheroid, 3, valve seat, 3a, sealing surface, 3d, valve body surface of contact, 4, the ripple spring, 5, pressure ring, 6, sealing gasket.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Figure 1:
A kind of metal hard-sealing ball valve valve seat, valve seat 3 are arranged between spheroid 2 and the valve body 1, structure ringwise, and a side is valve body surface of contact 3d, and opposite side is that valve body sealing surface 3a and spheroid 1 are fitted, and described valve body surface of contact 3d is provided with ripple spring 4, pressure ring 5, sealing gasket 6.
Described valve seat ripple spring 4 is two-way ripple spring, is arranged between described pressure ring 5, the valve body 1.
Described pressure ring 5; One end contacts with described ripple spring 4, and the other end contacts with described sealing gasket 6.
During valve closing, line pressure promotes spheroid 3 and valve seat 2.Valve seat 2 positions change extruding ripple spring 4, and ripple spring 4 elastic force act on pressure ring 5 and sealing gasket 6.Pressure increases sealing gasket 6 and reduces with valve seat 2 valve bodies 1 gap, and sealability improves relatively.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
