Description

Technical Field

[0001] This utility model belongs to the field of four-way valve technology, and in particular relates to a four-way valve body. Background Technology

[0002] A four-way valve is an essential control valve in refrigeration equipment, enabling air conditioning to switch between cooling and heating modes by changing the direction of medium flow. To address the energy loss caused by excessively rapid heat exchange when the refrigerant flows through the four-way valve and its piping, Chinese utility model patent application number 2023206758489 discloses a heat-insulated air conditioning four-way valve. Its structure includes a valve body and a valve core slidably disposed inside the valve body. A first pipe is located at the top of the valve body, and a second, third, and fourth pipe are located at the bottom. Each of the first, second, third, and fourth pipes has an insulated inner tube. The outer wall of the insulated inner tube and the inner wall of the first, second, third, and fourth pipes form a vacuum insulation cavity. However, installing the insulated inner tube inside the pipes is inconvenient and significantly reduces the space for medium flow within the pipes, which to some extent affects the production efficiency and performance of the four-way valve. Utility Model Content

[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a four-way valve body.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A four-way valve body includes a tubular valve body. A first pipe is provided on the upper side of the valve body, and a second pipe, a third pipe, and a fourth pipe are arranged side by side and spaced apart on the lower side. A connecting sleeve is sleeved on the surface of the valve body. The connecting sleeve has a first connecting pipe sleeved on the outside of the first pipe at the corresponding position of the first pipe, a second connecting pipe sleeved on the outside of the second pipe at the corresponding position of the second pipe, a third connecting pipe sleeved on the outside of the third pipe at the corresponding position of the third pipe, and a fourth connecting pipe sleeved on the outside of the fourth pipe at the corresponding position of the fourth pipe. A first through groove is opened on the front side of the connecting sleeve between the first connecting pipe and the third connecting pipe. A second through groove and a third through groove are respectively opened on the front side of the first connecting pipe and the third connecting pipe near the connecting sleeve.

[0006] Furthermore, the connecting sleeve includes an upper connecting cover and a lower connecting cover that are mated together on the surface of the valve body. A first connecting pipe is disposed on the upper connecting cover, and a second, third, and fourth connecting pipe are disposed on the lower connecting cover. A first groove is provided at the middle of the front side of the upper connecting cover, and a second groove is provided at the middle of the front side of the lower connecting cover. The first groove and the second groove are mated together to form a first through groove.

[0007] Furthermore, a first fixing ring is screwed together at the end of the first connecting pipe and the end of the first pipe, a second fixing ring is screwed together at the end of the second connecting pipe and the end of the second pipe, a third fixing ring is screwed together at the end of the third connecting pipe and the end of the third pipe, and a fourth fixing ring is screwed together at the end of the fourth connecting pipe and the end of the fourth pipe.

[0008] Furthermore, the first, second, third, and fourth fixing rings have the same structure, all including a fixing ring body, and an integrally formed annular stop edge is provided at the lower part of the inner wall of the fixing ring body. Internal threads are provided on the inner wall of the fixing ring body located above the stop edge and on the inner wall of the stop edge. The fixing ring body located on the inner wall of the stop edge is screwed together with the corresponding end of the connecting pipe, and the stop edge is screwed together with the corresponding end of the pipe.

[0009] Furthermore, gaps are provided between the first connecting pipe and the first pipe, between the second connecting pipe and the second pipe, between the third connecting pipe and the third pipe, and between the fourth connecting pipe and the fourth pipe.

[0010] Furthermore, the upper and lower connecting covers are fixed to the surface of the valve body with adhesive, and the surfaces of the upper and lower connecting covers are fixed together with multiple cable ties.

[0011] Furthermore, both ends of the valve body extend outwards, with upper and lower connecting covers at both ends.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] The four-way valve body of this invention features a connecting sleeve fitted onto the valve body surface, with connecting pipes fitted onto the connecting sleeve to the outside of each pipe, thus completely enclosing the four-way valve body and effectively reducing heat exchange of the fluid medium inside the valve body. Furthermore, a first through groove is formed on the front side of the connecting sleeve for installing a bracket on the outside of the four-way valve. Second and third through grooves are respectively formed on the front side of the first and third connecting pipes near the connecting sleeve for installing and fixing the first and second capillary tubes on the first and third connecting pipes, respectively, preventing the connecting sleeve and connecting pipes from constraining the installation structure on the valve body surface. This device is easy to manufacture and, while effectively reducing the heat exchange rate, does not change the flow rate or volume of the internal fluid medium, thus not affecting its performance in later use.
