Furthermore, a sealing ring is arranged between the valve cover and the valve body for sealing.

Further, the angular contact further comprises:

a first sealing surface disposed at a top end of the valve flap; the first sealing surface is welded on the valve clack in an inclined annular mode;

a second sealing surface disposed on a top end of one of the openings of the valve body at the second sealing surface; the second sealing surface is welded on the opening in an inclined annular mode;

furthermore, one end of the valve clack is set to be in a circular arc shape.

Further, the material of the first sealing surface and the second sealing surface is 13 Cr.

Further, the material of the valve flap is 20Cr 13.

The valve clack moves up and down in a cavity formed between the valve body and the valve cover under the action of a spring.

Compared with the prior art, a plurality of openings are arranged on any side surface of the valve body in a plurality of angles in the spatial direction; the structure can enable the pipelines with the inlet and the outlet which are not in the same direction to be connected, and the angle type check valve of the utility model is used for solving the technical problem that the two pipelines are arranged in a certain angle in the pipelines in the prior art, so that the check valve in the prior art cannot be used, the trend of the pipelines needs to be changed, and the application of the check valve is limited.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

An embodiment of the present invention relates to an angle check valve, as shown in fig. 1, including:

the valve body 1 serves as a body of the angle check valve in the present embodiment;

a plurality of openings 8 are arranged on any side surface of the valve body 1 in a plurality of angles in the spatial direction; the number of openings 8 in this embodiment is 2, with one opening 8; 2 openings 8 are arranged vertically, and one opening 8 is arranged below the valve body 1; the other opening 8 is provided at one side of the valve body 1.

Inside the valve body 1, a check member 10 is provided between any of the openings 8. The non-return means 10 in the present and in the present embodiment are arranged between 2 mutually perpendicularly arranged openings 8.

In order to achieve the technical effects, as shown in fig. 1, a valve cover 3 is fixed above a valve body 1 through bolts; one end of a check member 10 is embedded in the valve cover 3.

In order to achieve the above technical effects, as shown in fig. 1, the check member 10 further includes:

a valve flap 2, wherein the valve flap 2 is arranged at one end of the check part 10; one end of the valve clack 2 is embedded into the opening 8 below; an angle contact is formed between the valve clack 2 and the opening 8 below; sealing is achieved by angular contact structures.

The spring 5 is sleeved in one end of the spring 5 at one end of the valve clack 2, and the other end of the spring 5 is embedded in a round hole 6 in the valve cover 3; the other end of the spring 5 abuts against a boss 7 provided on the valve cover 3.

A sealing ring 4 is arranged between the valve cover 3 and the valve body 1 for sealing. Thus, the check part 10 realizes the function of one-way conduction of the check valve under the action of the pre-tightening force of the spring 5.

In order to achieve the above technical effects, as shown in fig. 1, the angular contact further includes:

is arranged at the top end of the valve clack 2 at the first sealing surface 12; the first sealing surface 12 is welded on the valve clack 2 in an inclined annular manner;

is arranged on the top end of one opening 8 of the valve body 1 at the second sealing surface 13; the second sealing surface 13 is welded on the opening 8 in an inclined annular manner; the material of the first sealing surface 12 and said second sealing surface 13 is 13Cr

In order to achieve the above-described technical effects, one end of the valve flap 2 is provided in an arc shape as shown in fig. 1.

The material of the valve clack 2 is 20Cr 13. The valve flap 2 moves up and down within the cavity formed between the valve body 1 and the valve cover 3 under the action of the spring 5.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the utility model, and that various changes in form and details may be made therein without departing from the spirit and scope of the utility model in practice.
