Description

Technical Field

[0001] The utility model belongs to the technical field of valves, relates to a three-way valve, and particularly relates to a combined lightweight three-way valve. Background Technique

[0002] When the three-way valve is in use, water flows in from the input end and flows out from the corresponding output end. In order for the two output ends to work and discharge water respectively in the existing three-way valve, there is a three-way valve with a ball valve installed inside, and there is also a type with a pipe body integrally connected inside the three-way valve.

[0003] Among them, the principle of the three-way valve with a connected pipe body is as follows: the output end of the pipe body is communicated with one of the output ends of the three-way valve, and the inner diameter of the input end of the pipe body is smaller than the inner diameter of the input end of the three-way valve. Therefore, when water passes between the pipe body and the three-way valve, the water flows out from the output end communicated with the input end of the three-way valve, and when water passes through the pipe body, the water flows out from the other output end of the three-way valve.

[0004] However, at present, the three-way valve with an internal pipe body and the pipe body are integrally formed. The defects caused by the integrally formed structure are: 1. Difficult to process, involving forming pipe fittings inside, which is difficult for the forming process and also difficult for forging, with low processing efficiency; 2. Heavy weight, unable to achieve the lightweight effect; 3. High cost. Summary of the Invention

[0005] The purpose of the utility model is to provide a combined lightweight three-way valve to solve the above problems for the problems existing in the prior art.

[0006] The purpose of the utility model can be achieved by the following technical solutions: A combined lightweight three-way valve includes a valve body with three ports, characterized in that a bent pipe is clamped and inserted in the valve body, the bent pipe is made of plastic material, a plurality of buckle mechanisms are formed on the bent pipe along its circumferential direction, and a plurality of positioning feet for preventing the radial rotation of the bent pipe are arranged between the bottom of the bent pipe and the valve body.

[0007] In the above-mentioned combined lightweight three-way valve, a positioning groove for positioning and clamping the positioning feet is formed on the inner wall of the valve body.

[0008] In the above-mentioned combined lightweight three-way valve, the buckle mechanism includes a buckle block and an elastic groove formed on the buckle block. The buckle block is integrally formed on the bent pipe, and the buckle block has a buckling part clamped in the valve body. An annular clamping groove for the buckling part to rebound and snap into is formed in the valve body.

[0009] In the above-mentioned combined lightweight three-way valve, both ends of the bent pipe are respectively an input end and an output end, the three ports of the valve body are respectively an input port, a first output port, and a second output port, the inner diameter of the input end is smaller than the inner diameter of the input port, and the output end is correspondingly communicated with the first output port.

[0010] Compared with the prior art, the combined lightweight three-way valve of the present invention has the advantages of reducing weight, reducing cost, being convenient for installation, efficient positioning, and reducing the processing difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0016] As Figure 1 , Figure 2 , Figure 3 shown, the combined lightweight three-way valve of the present invention includes a valve body 2 with three ports 1, a bent pipe 3 is snap-fitted and inserted into the valve body 2, the bent pipe 3 is made of plastic material, a plurality of snap mechanisms are formed on the bent pipe 3 along its circumferential direction, and a plurality of positioning feet 4 for preventing the radial rotation of the bent pipe 3 are arranged between the bottom of the bent pipe 3 and the valve body 2.

[0017] Specifically, a positioning groove for positioning and snapping the positioning feet 4 is formed on the inner wall of the valve body 2. In this embodiment, there are two positioning feet 4.

[0018] Specifically, the buckle mechanism includes a buckle block 5 and an elastic groove 6 formed in the buckle block 5. The buckle block 5 is integrally formed on the elbow pipe 3. The buckle block 5 has a buckling portion 7 that is buckled inside the valve body 2. An annular clamping groove 8 is formed inside the valve body 2 for the buckling portion 7 to rebound and snap into. When the elbow pipe 3 is installed, each buckling portion 7 on the elbow pipe 3 moves inward along the inner wall of the valve body 2. Since the elbow pipe 3 is made of plastic, each buckling portion 7 deforms and shrinks due to the corresponding elastic groove 6. After moving to the annular clamping groove 8, the buckling portion 7 rebounds outward and snaps into the annular clamping groove 8. At the same time, the positioning feet 4 at the bottom of the elbow pipe 3 correspond to the positioning grooves at the bottom of the valve body 2, so that the elbow pipe 3 achieves radial and axial positioning.

[0019] Specifically, the two ends of the elbow pipe 3 are respectively an input end and an output end, and the three ports 1 of the valve body 2 are respectively an input port, an output port 1 and an output port 2. The inner diameter of the input end is smaller than the inner diameter of the input port. The output end is correspondingly communicated with the output port 1. When water flows in between the input end and the input port, the water flows out from the output port 2. When water passes through the input end, the water flow passes through the output end and flows out from the output port 1.

[0020] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0021] Although terms such as port 1, valve body 2, elbow pipe 3, positioning feet 4, buckle block 5, elastic groove 6, buckling portion 7, annular clamping groove 8, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
