Description

Butterfly valve with waterproof hammer handle

Technical Field

The utility model relates to the technical field of handle butterfly valves, in particular to a waterproof hammer handle butterfly valve.

Background

The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like, and mainly has the functions of cutting off and throttling on a pipeline, the butterfly valve opening and closing member is a disc-shaped butterfly plate which rotates around the axis of the butterfly valve in the valve body, so that the purpose of opening and closing or adjusting is achieved, the butterfly valve is very widely used, the variety and the number of the used butterfly valve are still expanding continuously, the valve is developed towards high temperature, high pressure, large caliber, high tightness, long service life and excellent adjusting characteristics, and the valve is multifunctional, and the reliability and other performance indexes of the butterfly valve reach higher levels.

The handle butterfly valve in the prior art has some defects in the use process, such as damage caused by the impact of fluid when the butterfly plate is closed, and even deformation of the butterfly plate can be caused to influence the sealing effect.

Disclosure of Invention

The utility model discloses a handle butterfly valve with a waterproof hammer, which solves the problem that the handle butterfly valve in the prior art is easy to be damaged due to the impact of fluid when being closed.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the butterfly valve comprises a handle butterfly valve body, the port is fixedly connected with ring flange respectively about the handle butterfly valve body, the internal passage of handle butterfly valve body is provided with the butterfly plate, butterfly plate fixed connection is on the valve rod that is used for controlling its opening and shutting, the left and right sides of butterfly plate is provided with waterproof hammer mechanism respectively, waterproof hammer mechanism includes the buffer board through slide bar and butterfly plate sliding connection, the buffer chamber has been seted up to the inside of butterfly plate, the slide bar level penetrates the buffer intracavity and connects the stripper plate, fixedly connected with elastic buffer body on the opposite face of stripper plate and slide bar.

The joint of the sliding rod and the butterfly plate is provided with a sealing sliding sleeve.

The elastic buffer body is internally embedded with a buffer spring which is horizontally arranged.

The flange plate is provided with a plurality of mounting holes for connecting pipelines.

One end of the valve rod penetrating out of the handle butterfly valve body is fixedly connected with a handle.

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.
