After the technical scheme is adopted, compared with the prior art, the method has the following beneficial effects: can prevent that the butterfly valve from receiving fluid impact to cause the damage when closing, improve the performance of waterproof hammer, ensure the connection leakproofness between butterfly plate and the handle butterfly valve body, have higher practical value, can satisfy user's demand.
Drawings
In order to more clearly illustrate the embodiments of the utility model or the technical solutions of the prior art, the drawings which are used in the description of the embodiments or the prior art will be briefly described, it being obvious that the drawings in the description below are only some embodiments of the utility model, and that other drawings can be obtained according to these drawings without inventive faculty for a person skilled in the art.
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is an enlarged view of a portion a corresponding to fig. 1.
Reference numerals illustrate: the butterfly valve comprises a handle butterfly valve body 1, a flange plate 11, a butterfly plate 2, a valve rod 21, a handle 211, a buffer plate 3, a slide rod 31, a squeeze plate 4, an elastic buffer body 5 and a buffer spring 51.
Detailed Description
Referring to fig. 1-2, the technical scheme adopted in the specific embodiment is as follows: it contains handle butterfly valve body 1, port fixedly connected with ring flange 11 about handle butterfly valve body 1 respectively, the internal passage of handle butterfly valve body 1 is provided with butterfly plate 2, butterfly plate 2 fixed connection is on the valve rod 21 that is used for controlling its opening and shutting, the left and right sides of butterfly plate 2 is provided with waterproof hammer mechanism respectively, waterproof hammer mechanism includes through slide bar 31 and butterfly plate sliding connection's buffer board 3, buffer chamber 22 has been seted up to butterfly plate 2's inside, slide bar 31 level penetrates behind the buffer chamber 22 and connects stripper plate 4, fixedly connected with elastic buffer body 5 on the opposite face of stripper plate 4 and slide bar 31.
Wherein, the connection part of the slide bar 31 and the butterfly plate 2 is provided with a sealing sliding sleeve.
The elastic buffer body 5 is embedded with a buffer spring 51 horizontally arranged, and the elastic buffer body 5 may be made of a sponge or rubber body.
Wherein, the flange plate 11 is provided with a plurality of mounting holes for connecting pipelines.
Wherein, one end of the valve rod 21 penetrating out of the handle butterfly valve body 1 is fixedly connected with a handle 211.
The working principle of the utility model is as follows: when the butterfly plate is in a closed state, the butterfly plate is closed, the water flow is greatly fluctuated and generates a water hammer, the water hammer acts on the buffer plate and extrudes the buffer plate towards the direction of the butterfly plate, the extrusion plate extrudes the elastic buffer body, the elastic buffer body and the internal buffer spring compress and store energy, and the impact force generated by the elastic buffer body and the buffer spring acts on the buffer plate to achieve the effect of buffering, so that the impact of the water hammer on the butterfly plate is prevented.
The foregoing is merely illustrative of the present utility model and not restrictive, and other modifications and equivalents thereof may occur to those skilled in the art without departing from the spirit and scope of the present utility model.
