Description

One-way valve joint assembly

Technical Field

The utility model relates to a relevant goods field of check valve specifically is a check valve joint subassembly.

Background

The check valve is commonly called as a check valve, fluid can only flow along the water inlet, and the medium at the water outlet cannot flow back. The check valve is also called as a check valve or a check valve, is used for preventing reverse flow of oil flow in a hydraulic system or preventing reverse flow of compressed air in a pneumatic system, and has a straight-through type and a right-angle type. The straight-through one-way valve is installed on a pipeline through threaded connection, and the right-angle one-way valve has three forms of threaded connection, plate connection and flange connection.

However, the existing one-way valve joint assembly is too complex in structure, and air easily enters a pipeline when the one-way valve joint assembly is used, so that bacteria are generated in the pipeline and corroded, the service life is shortened, and certain defectiveness is realized.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a check valve joint subassembly to it is too complicated to provide current check valve joint subassembly structure in solving above-mentioned background art, and the pipeline is easily gone into to air when using, thereby leads to breeding the bacterium in the pipeline and corroded, reduces life problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a check valve joint subassembly, includes fixed skeleton, fixed skeleton is cavity form and inside fixed the inserting is equipped with the connecting pipe, the connecting pipe annular is provided with a plurality of wash ports, the fixed cover that has cup jointed in one side of fixed skeleton, the outside of connecting pipe is equipped with four arc closing plates, four be connected through a plurality of resilient means between the inner wall of arc closing plate and fixed skeleton.

Preferably, a plurality of the elastic devices are all springs, and the number of the elastic devices is three.

Preferably, the distance between adjacent four arc-shaped sealing plates is 0.3 mm.

Preferably, the plurality of drain holes are arranged at equal intervals.

Preferably, the inner wall of the fixing sleeve is provided with an internal thread matched with an external pipeline.

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

1. this check valve joint subassembly, the inside at fixed skeleton is installed to the connecting pipe, set up the fixed cover of being connected with the external pipeline in the outside of fixed skeleton, rivers get into by the water inlet of connecting pipe, discharge by the wash port on the connecting pipe again, thereby the pressure that produces when rivers flow backs down arc closing plate compression resilient means, make discharge roughly equivalent with normal water, thereby arc closing plate takes place the kick-back automatically under resilient force of resilient means and shelters from the wash port on the connecting pipe when rivers do not flow, make its air difficult inflow inside, the utility model discloses simple structure, convenient operation can avoid the air to enter into the pipeline when using in, guarantees the saturation of pipe-line system water.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, the present invention provides an embodiment: a check valve joint assembly comprises a fixed framework 1, wherein the fixed framework 1 is hollow and is fixedly inserted with a connecting pipe 2, the connecting pipe 2 is annularly provided with a plurality of drain holes 3, one side of the fixed framework 1 is fixedly sleeved with a fixed sleeve 4, the outer side of the connecting pipe 2 is provided with four arc-shaped sealing plates 5, the four arc-shaped sealing plates 5 are connected with the inner wall of the fixed framework 1 through a plurality of elastic devices 6, concretely, the connecting pipe 2 is arranged in the fixed framework 1, the outer side of the fixed framework 1 is provided with the fixed sleeve 4 connected with an external pipeline, water flows in from a water inlet of the connecting pipe 2 and then is discharged from the drain holes 3 on the connecting pipe 2, when the water flows, the arc-shaped sealing plates 5 are pushed open to compress the elastic devices 6, so that the water flow is approximately equal to normal water, when the water flows, the arc-shaped sealing plates 5 automatically rebound under the resilience force of the elastic devices 6 to shield the drain, so that air is not easily flowed into the interior.

Further, a plurality of resilient means 6 are the spring, and the quantity is three, and the degree of going back is high, and resilience performance is strong.

Further, the distance between adjacent four arc-shaped sealing plates 5 is 0.3 mm.

Further, the plurality of drain holes 3 are arranged at equal intervals.

Furthermore, the inner wall of the fixed sleeve 4 is provided with an internal thread 7 matched with an external pipeline, so that the fixed sleeve is conveniently connected with the external pipeline.

The working principle is as follows: at first connecting pipe 2 is installed in the inside of fixed skeleton 1, set up the fixed cover 4 of being connected with the external pipeline in the outside of fixed skeleton 1, rivers get into by the water inlet of connecting pipe 2, discharge by wash port 3 on connecting pipe 2 again, thereby the pressure that produces when rivers flow backs away arc closing plate 5 compression resilient means 6, make discharge roughly equivalent with normal water, thereby arc closing plate 5 takes place the kick-back automatically under resilient force of resilient means 6 and shelters from wash port 3 on the connecting pipe 2 when rivers do not flow, make its air difficult to flow into inside.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
