Abstract

The utility model discloses a novel self sealss check valve, its structure includes the valve body, sets up the case in valve body center department, the case runs through behind the valve body and the spacing ring welding, valve body one end is equipped with the dog, the dog with be equipped with the spring between the spacing ring. The water outlet of the valve core is designed to be conical, so that the flow resistance coefficient of a medium is greatly reduced, and the elastic sealing rings are additionally arranged on the positions where the valve core and the valve body are impacted and on the two sides of the upper end of the valve body, so that the valve core is simple in structure, is light and small in size, and is greatly enhanced in practicability, service life and sealing performance.

Description

Novel self-sealing check valve

Technical Field

The utility model relates to a check valve technical field especially relates to a novel self sealss check valve.

Background

The check valve is mainly used for preventing media in the pipeline from flowing backwards and is a valve capable of automatically stopping the fluid from flowing backwards. The flap of the check valve opens under fluid pressure, which flows from the inlet side to the outlet side. When the pressure at the inlet side is lower than that at the outlet side, the valve clack automatically closes under the action of fluid pressure difference, self gravity and other factors to prevent the fluid from flowing backwards.

At present, the check valve on the market has the problems of complex structure, large flow resistance and poor sealing effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: in order to solve the problems, a novel self-sealing check valve is provided.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel self sealss check valve, the structure includes valve body (1), sets up case (2) in valve body (1) center department, case (2) run through behind valve body (1) and spacing ring (3) welding, valve body (1) one end is equipped with dog (4), dog (4) with be equipped with spring (5) between spacing ring (3).

As a further description of the above technical solution:

the outlet of the valve core (2) is conical.

As a further description of the above technical solution:

and an elastic sealing ring (6) is arranged on the contact surface of the valve core (2) and the valve body (1).

As a further description of the above technical solution:

and elastic sealing rings (6) are respectively arranged at two ends of the outer surface of the valve body (1).

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses be coniform with case (2) export, when the medium produced pressure to case (2) and passed through case (2), because the circular cone structure of case (2) is very big has reduced the resistance that case (2) caused to the medium.

2. The utility model discloses case (2) are equipped with elastic sealing circle (6) with valve body (1) contact surface, and when case (2) lost the medium to its pressure that causes, will rebound valve body (1) under the effort of spring (5), at this moment elastic sealing circle (6) not only can prevent that case (2) directly from striking valve body (1) and causing the damage, can also promote the sealed effect of valve.

3 the utility model discloses valve body (1) surface both ends respectively are equipped with elastic seal circle (6), and its effect makes valve body (1) be connected with the medium pipe and can have better sealed effect.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following further describes embodiments of the present invention with reference to the accompanying drawings:

as shown in fig. 1 to 3, this embodiment discloses a novel self sealss check valve, and the structure includes valve body (1), sets up case (2) in valve body (1) center department, case (2) run through behind valve body (1) and spacing ring (3) welding, valve body (1) one end is equipped with dog (4), dog (4) with be equipped with spring (5) between spacing ring (3), the utility model discloses there is overall structure light, small and exquisite, simple to operate, characteristics that the practicality is strong.

Specifically, as shown in fig. 3, the utility model relates to a novel self sealss check valve, case (2) export are coniform, very big reduction the circulation resistance that the medium received.

Specifically, as shown in fig. 2 and 3, the utility model relates to a novel self sealss check valve, case (2) are equipped with elastic sealing circle (6) with valve body (1) contact surface, but prevent that case (2) from directly striking valve body (1) when the valve uses, and cause the damage, can also prevent the medium refluence, have played the effect that increases valve life-span and sealing performance.

Specifically, as shown in fig. 1 to 3, the utility model relates to a novel self sealss check valve, valve body (1) surface both ends respectively are equipped with elastic sealing circle (6), have promoted the sealed effect when valve body (1) lies in the medium pipe and connects, prevent that the medium from leaking.

The above is an embodiment of the present invention, and is not intended to limit the scope of the present invention, which is defined by the claims in the claims, and all equivalent changes and modifications made by the present invention are within the scope of the present invention.
