Abstract
An embodiment of the utility model discloses a valve seat for a metal-seated ball valve with a sealing face of a lip-type elastic compensation structure. The ball valve comprises a valve body, a ball is arranged in the valve body, the valve seat is arranged at the connecting position of the valve body and the ball, and the sealing face of the valve seat is of an elastic lip-type compensation structure. The valve seat is of the lip-type elastic compensation structure and can compensate the size of the sealing face of the metal-seated ball valve, the size of the sealing face of the metal-seated ball valve can be compensated automatically, and minimum leakage even zero leakage of the metal-seated ball valve is achieved.
Description
Technical field
The utility model relates to a kind of metal seal ball valve, relates in particular to metal seal ball valve sealing surface lip formula elastic compensating structure valve seat.
Background technique
At present, the domestic metal seal ball valve sealing surface that manufactures and designs adopts metal seat valve. and generally be the rigidity valve seat, because there not being sealing compensation automatically, cause sealing surface to leak easily during sealing.
The model utility content
The utility model embodiment technical problem to be solved is, a kind of closure size error that can compensate automatically after valve seat and the spheroid assembling is provided, and makes the more reliable sealing surface lip formula elastic compensating structure valve seat of metal seal ball valve sealing.
Described metal seal ball valve sealing surface lip formula elastic compensating structure valve seat, described valve body and spheroid joint are provided with valve seat, and described sealing surface of seat is elasticity lip formula collocation structure sealing surface.
There is an elastic groove C in the cross section of described elasticity lip formula collocation structure.
Described elasticity lip formula collocation structure is the Hardmetal materials collocation structure.
Implement the utility model embodiment, have following beneficial effect:
The utility model is a kind of lip formula elastic compensating structure valve seat that can compensate the metal seal ball valve size of seal contact face.Thereby the size of metal seal ball valve sealing surface can be compensated automatically. realize that the minimum leakage of metal seal ball valve is until zero leakage.
Description of drawings
Fig. 1 is the utility model sealing surface lip formula elastic compensating structure valve seat construction schematic representation;
Fig. 2 is the metal seal ball valve partial structurtes schematic representation that the utility model sealing surface lip formula elastic compensating structure valve seat relates to.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail.
A kind of metal seal ball valve sealing surface of present embodiment lip formula elastic compensating structure valve seat, ball valve comprises valve body 1, spheroid 2, valve body 1 is provided with valve seat 3, fixed plate 5 with spheroid 2 joints, wherein, sealing surface of seat 4 is cemented carbide elasticity lip formula collocation structure sealing surface, and there is an elastic groove C in the cross section of elasticity lip formula collocation structure valve seat.
As shown in fig. 1, lip formula resilient seal surface can utilize elastic groove C to adjust the elasticity of B portion, thereby has adjusted sealing surface of seat A size.From Fig. 2, after valve body 1, spheroid 2, fixed plate 5, valve seat 3, the assembling, because the accessory size cumulative error, dimensional chain for assembly L possibility deviation theory size makes and sealing surface of seat A and the locking of ball seal face causes ball normally not open and close.In the case, the sealing surface of valve seat 4 distinctive lip formula elastic compensating structures then can utilize the elasticity of the valve seat lip elastic structure shown in Fig. 1 compensate automatically the assembling in size L, make sealing surface of seat A can be close to the ball seal face and be unlikely to locking again, thus the optimal seal effect of realization ball valve.
Above disclosed only is a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of doing according to the utility model claim still belongs to the scope that the utility model is contained.
Claims (2)
1. the sealing surface lip formula elastic compensating structure valve seat of a metal seal ball valve, ball valve comprises valve body (1), spheroid (2), and described valve body (1) is provided with valve seat (3) with spheroid (2) joint, it is characterized in that described sealing surface of seat (4) is elasticity lip formula collocation structure sealing surface.
2. the sealing surface lip formula elastic compensating structure valve seat of metal seal ball valve according to claim 1 is characterized in that there is an elastic groove C in the cross section of described elasticity lip formula collocation structure.
