Description

Technical Field

[0001] This invention belongs to the field of four-way valve technology, and in particular relates to a four-way valve body that is easy to control. Background Technology

[0002] Four-way valves are widely used in refrigeration equipment and mechanical hydraulic equipment. A four-way valve generally consists of a valve body and four connecting pipes installed on the valve body. In traditional four-way valves, the connecting pipes are mostly perpendicular to the axis of the valve body. However, under certain special working conditions, this can cause trouble in connecting the connecting pipes to the equipment control pipeline. Furthermore, common non-electrically controlled four-way valves cannot control the flow of the connecting pipes as needed. Therefore, it is necessary to improve the valve body of the existing four-way valve. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a four-way valve body that is easy to control, which can realize the control of different passages between pipes in a non-electrically controlled structural design.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A conveniently controllable four-way valve body includes a cylindrical body, one end of which is closed and the other end is open, with an end cap detachably installed at the open end. The side wall of the body is provided with an upper pipe, a lower pipe, and side pipes on the left and right sides. Each pipe includes a connecting part and an external connecting part, and the connecting part of each pipe is connected to the body. The external connecting part of each pipe is parallel to the axis of the body. The connecting parts of the left and right side pipes are connected to the body by a connecting pipe inside, and several connecting holes are provided on the side of the connecting pipe facing the end cap. A sealing element can be detachably installed on each of the connecting holes.

[0006] Furthermore, the external connections of each receiver extend toward the closed end of the main body.

[0007] Furthermore, the distance between the connecting pipe and the end cap is less than the distance between the connecting portion of the upper pipe and the end cap.

[0008] Furthermore, the distance between the connecting portion of the upper pipe and the end cap is less than the distance between the connecting portion of the lower pipe and the end cap.

[0009] Furthermore, the external connections of each pipe are all equidistant from the axis of the main body.

[0010] Furthermore, each of the connecting holes is a threaded hole, and the sealing component includes a screw plug screwed into the connecting hole, with a screw plug sealing gasket provided on the screw plug.

[0011] Furthermore, the connecting tube has a milled surface on the side facing the end cap, and each connecting hole is provided on the milled surface.

[0012] Furthermore, the end cap includes a cover plate and a connecting section. The connecting section of the end cap is threaded onto the open end of the body, and the cover plate of the end cap is provided with an end cap sealing gasket on the side facing the body.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] This invention features a simple and rationally designed structure. By installing or removing the sealing component, different passages of the four-way valve body can be controlled. When all the connecting holes of the connecting pipe are sealed with the sealing component, the side pipes on the left and right sides form passages, and the side pipes are not connected to the upper or lower pipes. When the sealing component is removed, the connecting holes on the connecting pipe are connected to the inner cavity of the valve body, thus forming passages for the upper pipe, lower pipe, and the side pipes on both sides. This structural design allows the four-way valve body to be adapted to different usage requirements, improving the versatility of the four-way valve. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] A conveniently controllable four-way valve body, such as Figures 1 to 6 As shown, the device includes a cylindrical body 1, with one end being a closed end 2 and the other end being an open end. An end cap 3 is detachably installed at the open end. In an optional embodiment, the end cap includes a cover plate and a connecting section 14. The connecting section 14 of the end cap is threaded onto the open end of the body. The cover plate 15 of the end cap has an end cap sealing gasket 16 facing the body. The side wall of the body is provided with an upper connecting pipe 4, a lower connecting pipe 5, and side connecting pipes 6 on the left and right sides. Each connecting pipe includes a connecting part 7 and an external connecting part 8. The connecting part of each connecting pipe is connected to the body, and the external connecting part of each connecting pipe is parallel to the axis of the body.

[0028] The side pipes on the left and right sides are symmetrically arranged. The connecting parts of the left and right side pipes are connected by a connecting pipe section 9 inside the main body. Several connecting holes 10 are provided on the side of the connecting pipe section facing the end cap. A sealing element 11 can be detachably installed on each connecting hole. The open end serves as the operating port for controlling the four-way valve body. The sealing element can be operated in this operating port. Specifically, the end cap can be unscrewed and removed, and then the sealing element of the connecting pipe section can be installed or removed inside the main body. Then, the upper end cap can be screwed on to close the main body, which can easily realize the control of different passages of the four-way valve body. For example, when all the connecting holes of the connecting pipe are closed by using the sealing element, the side pipes on the left and right sides form a passage, and the side pipes are not connected to the upper and lower pipes. However, when the sealing element is removed, the connecting holes on the connecting pipe are connected to the inner cavity of the main body, thereby making the upper pipe, lower pipe, and the side pipes on both sides form passages.

[0029] All external connections of the connecting pipes extend towards the closed end of the main body. The distance between the connecting pipe and the end cap is less than the distance between the connecting portion of the upper connecting pipe and the end cap. The distance between the connecting portion of the upper connecting pipe and the end cap is less than the distance between the connecting portion of the lower connecting pipe and the end cap. The external connections of all connecting pipes are equidistant from the axis of the main body, resulting in a more rounded shape for the four-way valve body. In one optional embodiment, the connecting portions of the left and right connecting pipes are integrally formed with the connecting pipe portion. In further improved embodiments, such as... Figure 7 As shown, the side pipes and connecting pipes on the left and right sides are integrally formed.

[0030] In an optional embodiment, each of the connecting holes is a threaded hole, and the sealing member includes a screw plug screwed into the connecting hole, with a screw plug sealing gasket 12 provided on the screw plug. For example, the screw plug is an internal hexagonal screw plug. In a further improved embodiment, the connecting tube has a milled surface 13 on the side facing the end cap, and each connecting hole is located on the milled surface. When the screw plug is installed on the connecting tube and tightened, the screw plug presses the sealing gasket against the milled surface, thus forming a good seal between the screw plug and the connecting tube.

[0031] This invention features a simple and rationally designed structure. By installing or removing the sealing component, different passages of the four-way valve body can be controlled. When all the connecting holes of the connecting pipe are sealed with the sealing component, the side pipes on the left and right sides form passages, and the side pipes are not connected to the upper or lower pipes. When the sealing component is removed, the connecting holes on the connecting pipe are connected to the inner cavity of the valve body, thus forming passages for the upper pipe, lower pipe, and the side pipes on both sides. This structural design allows the four-way valve body to be adapted to different usage requirements, improving the versatility of the four-way valve.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
