Abstract

The utility model relates to an elastic valve seat of a ball valve, which is particularly applicable to a cast stone ball valve and belongs to the technical field of elastic valve seats of ball valves. The elastic valve seat of the ball valve is characterized by a seal ring structure; both ends of the seal ring structure are respectively provided with first grooves (8), the middle part thereof is provided with a second groove (9) and the bottom part thereof is provided with a convex ring (10) which forms linear sealing with a ball body (4). The elastic valve seat of the ball valve has the advantages of reasonable structural design, time and labor saving when in opening and closing, convenient operation, good sealing performance and long service life.

Description

The ball valve elastic seat
Technical field
The utility model relates to a kind of ball valve elastic seat, is specially adapted to the cast stone ball valve, belongs to ball valve elastic seat technical field.
Background technique
At present, the known valve seat that is used for the cast stone ball valve, the valve seat insert angle is too big, and is big with the spheroid area of contact, embraces the tight of ball newspaper, and the moment of generation is just big, valve seat insert wearing and tearing aggravation, and open and close difficulty.
Summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and the ball valve elastic seat of a kind of reasonable in design, easy to operate, good seal performance, long service life is provided.
The utility model is achieved through the following technical solutions:
Ball valve elastic seat, special way are to be ring structure, and two ends are respectively equipped with first groove 8, and the middle part is provided with second groove 9, and the bottom is provided with the bulge loop 10 that forms linear sealing with spheroid 4.
The utility model ball valve elastic seat, reasonable in design has and opens and closes time saving and energy saving, easy to operate, good seal performance, long service life.
Description of drawings
Fig. 1: valve body 1 structural representation that ball valve elastic seat 7 is installed;
Fig. 2: the structural representation of the utility model ball valve elastic seat.
Among the figure: 1, valve body, 2, flow channel, 3, discharge route, 4, spheroid, 5, upper valve rod, 6, lower valve rod, 7, the ball valve elastic seat, 8, first groove, 9, second groove, 10, bulge loop.
Embodiment
Provide embodiment of the present utility model below with reference to accompanying drawing, be used for formation of the present utility model is described further.
Embodiment 1
The ball valve elastic seat of present embodiment is applied to valve body 1, the two ends of valve body 1 are respectively equipped with flow channel 2, discharge route 3, spheroid 4 two ends in the valve body 1 are connected with upper valve rod 5 respectively, lower valve rod 6, valve body 1 is provided with the ball valve elastic seat 7 that is used with spheroid 4, spheroid 4 forms sealing configuration with ball valve elastic seat 7, ball valve elastic seat 7 is respectively equipped with first groove 8 for two ends, the middle part is provided with second groove 9, the bottom is provided with the seal ring that forms the bulge loop 10 of linear sealing with spheroid 4, the effect of first groove 8 is to make itself and second groove 9 constitute less crane span structure, the resiliently deformable that helps valve seat part, in use be in the valve seat of valve body entrance point, pressure medium enters second groove 9, in first groove 8, forcing valve seat to be close to spheroid seals, the effect of bulge loop 10 is to form linear sealing with spheroid 4, area of contact is little, and switch is time saving and energy saving.
The ball valve elastic seat of present embodiment, reasonable in design has and opens and closes time saving and energy saving, easy to operate, good seal performance, long service life.
