Abstract
The utility model discloses a butterfly valve seat, including annular barrel, being provided with the first shaft hole and the second shaft hole of same axis on the section of thick bamboo wall of annular barrel, the inner wall of annular barrel is provided with first axle bed and the second axle bed that corresponds first shaft hole and second shaft hole, and its characteristics are: still be provided with the catch ring seat on the inner wall of the annular barrel between first axle bed and the second axle bed. The utility model discloses during the use, the inner wall of annular barrel not with dish board direct contact, but the contact of catch ring seat and dish board has avoided the inner wall of annular barrel to be worn and torn long service life.
Description
Technical field
The utility model belongs to butterfly valve technical field, especially relates to a kind of butterfly valve seat.
Background technique
Cement, often uses a kind of butterfly valve carried powder material in the industries such as boats and ships, valve seat is one of significant components of butterfly valve, butterfly valve in off position time, valve seat and dish plate close contact, cause powder material to be stopped.Existing butterfly valve in use, owing to there is much fine solid particles impurity in powder material, so butterfly valve is easily blocked by fine solid particles between valve seat and dish plate when cutting out, cause the inner wall abrasion of valve seat, of long duration also can causing leaks, so that need to change butterfly valve, bring a lot of trouble, be therefore necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of butterfly valve seat, it have structure simple, prevent inwall to be worn and the feature of long service life.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of butterfly valve seat, comprise circular cylinder, the barrel of described circular cylinder is provided with the first axis hole and second axis hole of same axis, the inwall of described circular cylinder is provided with the first axle bed and second axle bed of corresponding first axis hole and the second axis hole, and the inwall of the circular cylinder between described first axle bed and the second axle bed is also provided with stop ring seat.
Described stop ring seat and circular cylinder, the first axle bed and the second axle bed are formed in one and manufacture, and the surface of described stop ring seat is round and smooth.
After adopting said structure, the utility model is compared to the prior art advantageously: structure of the present utility model is simple, and during use, the inwall of circular cylinder does not directly contact with dish plate, but stops that ring seat contacts with dish plate, the inwall avoiding circular cylinder is worn, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of A-A in Fig. 1.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, see shown in Fig. 1 to Fig. 2: a kind of butterfly valve seat, comprise circular cylinder 1, the barrel of described circular cylinder 1 is provided with the first axis hole 11 and the second axis hole 12 of same axis, the inwall of described circular cylinder 1 is provided with the first axle bed 13 and second axle bed (accompanying drawing does not draw) of corresponding first axis hole 11 and the second axis hole 12, the inwall of the circular cylinder 1 between described first axle bed 13 and the second axle bed is also provided with the stop ring seat 14 that surface is round and smooth, described stop ring seat 14 is formed in one with circular cylinder 1, first axle bed 13 and the second axle bed and manufactures.When the utility model uses, the inwall of circular cylinder 1 does not directly contact with dish plate, but stops that ring seat 14 contacts with dish plate, and the inwall avoiding circular cylinder 1 is worn, long service life, stops the surface energy minimizing resistance that ring seat 14 is round and smooth.
