Problems solved by technology

The one-way valve is a one-way valve, and the muffler is a muffler. The separate design not only increases the production cost and material cost of the device itself, but also affects mass production efficiency because of two more installation processes.
Moreover, the original one-way valve housing needs to be casted and subjected to a large number of boring processes, the structure is complex, and the final assembly process requires at least four positioning and three welding processes to complete
The processing technology is complicated, the waste of materials is high, and the production efficiency is low

Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the composite check valve of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] refer to Figure 1 to Figure 3 , the composite check valve according to an embodiment of the present invention includes a check valve body and a valve core 4 placed in the check valve body.

[0022] The one-way valve body includes a fluid inlet pipe 2 , a cylinder body 3 and a fluid outlet pipe 6 . The fluid inlet pipe 2 is embedded in the cylinder body 3 , and the fluid outlet pipe 6 is also embedded in the cylinder body 3 . The cylinder 3 serves as the muffler cylinder. Both the fluid inlet pipe 2 and the fluid outlet pipe 6 are sealed with the cylinder bod...

Abstract

The invention provides a composite one-way valve. The composite one-way valve comprises a one-way valve body and a valve core arranged in the one-way valve body. The one-way valve body comprises a fluid inlet pipe, a barrel and a fluid outlet pipe, both the fluid inlet pipe and the fluid outlet pipe are embedded in the barrel, one end of the valve core is arranged on the fluid outlet pipe, and the other end of the valve core is abutted against and seals the fluid inlet pipe. The valve core is arranged in the barrel of the one-way valve body, one end of the valve core is arranged on the fluid outlet pipe of the one-way valve body, and the other end of the valve core is abutted against and seals the fluid inlet pipe of the one-way valve body, so that functions of the one-way valve are realized. Fluid enters the barrel from the fluid inlet pipe and flows out of the barrel from the fluid outlet pipe after being subjected to noise reduction in the barrel, so that the composite one-way valve has the functions of conducting in one way and eliminating noise, and in the engineering application with the functions of one-way conduction and silencing, mounting procedures can be reduced, and engineering mounting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to a composite check valve. Background technique [0002] At present, the one-way valve and the muffler in the engineering system (especially for the air conditioning system) are separated. The one-way valve is a one-way valve, and the muffler is a muffler. The separate design not only increases the production cost and material cost of the device itself, but also affects the mass production efficiency because of two more installation processes. Moreover, the original one-way valve housing needs to be casted and subjected to a large number of boring processes, and the structure is complex. The final assembly process requires at least four positioning and three welding processes to complete. Its processing technology is complicated, material waste degree is high, and production efficiency is on the low side. Contents of the invention [0003] In view of the status quo of the ...
