Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a combined valve that is easy to connect. Background Art

[0002] The valve is a control component in the pipeline fluid delivery system, which is used to change the cross-section of the passage and the flow direction of the medium. Valves are classified into various types according to the material, such as cast iron valves, cast steel valves, stainless steel valves, etc. According to the number of pipelines controlled by the valve, the valve can also be divided into two-way valves, three-way valves, etc. The function of the valve is to control the flow, pressure and flow direction of the pipeline. However, the valves in the prior art usually have independent functions and single functions. When a different valve needs to be replaced, the valve needs to be replaced as a whole, which makes replacement inconvenient.

[0003] According to the disclosed combined valve and piping system (publication number: CN107940059A), the above application includes three parts: a valve body, a first connection part, and a second connection part. The first connection part and the second connection part are respectively arranged at both ends of the valve body, and both the first connection part and the second connection part are connected to the valve body. The valve can be connected to the piping system through the first connection part and the second connection part to achieve a variety of fluid controls. In addition, the first connection part is non-detachably connected to the valve body, and the second connection part is detachably connected to the valve body. When replacing the valve, the second connection part can be replaced.

[0004] However, in actual use, the above-mentioned device only connects the connecting parts through protrusions. When the water flow is too large or an impact occurs, the connecting parts may be separated from the connecting parts, resulting in insufficient reliability between the valve body and the connecting parts. In view of this, we propose a combination valve that is easy to connect. Utility Model Content

[0005] The purpose of the utility model is to provide a combined valve that is easy to connect, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combination valve that is easy to dock, including a valve body, one side of the valve body is fixedly connected to one end of a connecting part, the other end of the connecting part is sleeved with a connecting pipe, the side of the connecting pipe close to the connecting part is fixedly connected to a connecting assembly, the connecting assembly includes a clamping part, the side of the connecting pipe close to the connecting part is fixedly connected to the clamping part, the clamping part is sleeved with a clamping groove on the inner wall of the connecting part, the side wall of the connecting pipe is sleeved with a waterproof gasket, one end of a movable rod is sleeved in the clamping groove, the other end of the movable rod passes through the side wall of the connecting part, the inner wall of the connecting part is provided with a cavity, the inner wall of the cavity is abutted with a waterproof ring, and the waterproof ring is sleeved with the outer wall of the movable rod.

[0007] Optionally, a mounting seat is fixedly connected to the inner wall of the valve body, and a check valve plate is rotatably connected to the side wall of the mounting seat.

[0008] Optionally, the inner wall of the valve body is rotatably connected to a ball valve body, the side wall of the ball valve body is penetrated by a through hole, the top end surface of the ball valve body is fixedly connected to one end of a connecting rod, the other end of the connecting rod penetrates the top end surface of the valve body and is fixedly connected to the rotating wheel.

[0009] Optionally, the axes of the valve body and the connecting parts coincide with each other.

[0010] Optionally, the other side of the valve body is sleeved with another pipe body.

[0011] Optionally, a rubber pad is provided at the sleeve connection portion between the connecting rod and the valve body, thereby improving the sealing performance of the valve body.

[0012] Compared with the prior art, the utility model provides a combination valve that is easy to connect and has the following features:

[0013] Beneficial effects:

[0014] 1. In order to improve the reliability of the connection between the valve body and the connecting part, the connecting parts are aligned with each other, and the connecting part is moved horizontally to the left. The engaging part encounters the side wall of the connecting part and deforms, and then enters the interior of the connecting part and engages with the slot on the inner wall of the connecting part. The engaging part pushes the movable rod. When the connecting part needs to be disassembled, the movable rod is pressed to push the engaging part to separate from the slot, and the connecting part can be further moved to the right to separate from the connecting part, thereby improving the reliability of the connection between the valve body and the connecting part. The waterproof gasket improves the sealing between the connecting part and the connecting pipe, and the waterproof ring improves the sealing between the movable rod and the connecting part, thereby improving the overall sealing effect of the combined valve.

[0015] 2. In order to prevent water from flowing back, the inner wall of the valve body of this combination valve that is easy to dock is fixedly connected to a mounting seat, and the side wall of the mounting seat is rotatably connected to a check valve. When the water flows from right to left, the water pushes the check valve open and can flow normally. When the sluice gate is closed, the water flow will have a water hammer effect, which will cause the water to flow back. At this time, the check valve closes to further prevent the water from flowing back.

[0016] 3. In order to control the size of the water flow, the inner wall of the valve body is rotatably connected to the ball valve body, and the side wall of the ball valve body is penetrated with a through hole. The top end face of the ball valve body is fixedly connected to one end of a connecting rod, and the other end of the connecting rod penetrates the top end face of the valve body and is fixedly connected to the rotating wheel. By rotating the rotating wheel, the connecting rod is driven to rotate, and the ball valve body can be rotated to further adjust the position of the through hole, thereby controlling the size of the water flow.
