Description

Novel plunger valve

Technical Field

The utility model relates to the field of mechanical industry, specifically a novel plunger valve.

Background

At present, the mechanical production and processing field in China is reputable by the national heavy equipment, but the plunger valve in the mechanical industry on the market has the problems of poor sealing performance and excessive water impurities at the inlet and the outlet of a pipeline, so that the plunger valve is easy to block, and a novel plunger valve is provided.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide a novel plunger valve to solve the not good and too much easy problem of blockking up of quality of water impurity of pipeline import and export of the sealing performance that provides among the above-mentioned background art.

(II) technical scheme

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel plunger valve, includes the valve body, is provided with the valve rod in the middle of the valve body is inside, and the valve body both sides are provided with elastic seal gasket, and the valve rod below is provided with the plunger, and the plunger circumferencial direction is provided with the hole frame, and the valve rod circumferencial direction is provided with the valve gap, and the valve gap middle part is provided with the screw, and the valve rod top is provided with the hand wheel, and.

Further, the two screws are symmetrically distributed on two sides of the valve rod at proper distances, and the upper valve rod and the lower valve rod are fastened and connected.

Further, the plunger is approximately cylindrical in shape, and the length of the plunger is larger than the distance between the upper side and the lower side of the inner side of the pipeline.

Furthermore, the elastic sealing gasket is made of deformable materials, the width dimension of the elastic sealing gasket is larger than the maximum outer diameter of the pipeline on one side, and the diameter of the arranged inner side aperture is smaller than the diameter of the inner side of the pipeline when the inner side aperture is expanded.

Further, the automatic filter screen is arranged at a proper position inside two sides of the pipeline, the size of the automatic filter screen is matched into interference fit, and the shape of the automatic filter screen is consistent with the shape of the inner side of the pipeline.

(III) advantageous effects

Compared with the prior art, the beneficial effects of the utility model are that:

(1) this kind of novel plunger valve through setting up at the inside automatic filter screen of pipeline, filters quality of water intaking the water-out in-process, through such design, reaches the purpose that whole plunger valve possesses the automatic filtration impurity.

(2) This kind of novel plunger valve through the elastic sealing gasket who sets up in the pipeline mouth outside of valve body both sides, seals the pipeline interface when intaking and go out water, through such design, has solved the not good problem of pipeline interface department sealing performance.

FIG. 3 is a partial enlarged view of the present invention;

in the figure: 1. a valve body; 2. an elastic sealing gasket; 3. a hole frame; 4. a plunger; 5. a valve stem; 6. a hand wheel; 7. a valve cover; 8. a screw; 9. automatic filter screen.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a novel plunger valve, includes valve body 1, is provided with valve rod 5 in the middle of valve body 1 is inside, and 1 both sides of valve body are provided with

elastic seal gasket

2, and 5 below of valve rod are provided with

plunger

4, and 4 circumferencial directions of plunger are provided with

hole frame

3, and 5 circumferencial directions of valve rod are provided with valve gap 7, and valve gap 7 middle part is provided with

screw

8, and 5 tops of valve rod are provided with hand wheel 6, and 1 inside both sides of valve body are provided with automatic.

In this example, the two screws 8 are symmetrically arranged on both sides of the valve rod 5 at a proper distance, and fasten the upper and lower valve rods 5.

In this example, the plunger 4 is approximately cylindrical in shape and should be longer than the distance up and down the inside of the pipe.

In this example, the elastic sealing gasket 2 is a deformable material, and the width dimension thereof is larger than the maximum outer diameter of the single-sided pipe, and the inner diameter of the elastic sealing gasket is smaller than the inner diameter of the pipe when the inner diameter is extended.

In this example, the automatic filter screens 9 are placed in appropriate positions inside the two sides of the duct, are sized to fit in an interference fit, and are shaped to conform to the inside of the duct.

The utility model discloses a theory of operation and use flow: the utility model discloses install the back, at first inspect the utility model discloses a pipeline has all been connected in installation fixed and safety protection with plunger valve import and exit, during the installation, fix elastic seal gasket and carry out the buckle to getting into the pipeline, it ends to be rotatory hand wheel through the plunger when needs, automatic filter screen filters impurity at business turn over water in-process automation, the inside jam of anti-positive pipeline, realizes solving the not good function of conventional plunger valve sealing performance and the too much easy problem of blockking up of quality of water impurity is imported and exported to pipeline at last, the utility model discloses simple structure, convenience safe in utilization.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
