Description

Technical Field

[0001] This utility model relates to a flow control valve, specifically a multi-pipe flow control valve. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, diversion, and overflow / pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in highly complex automated control systems, with a wide variety of types and specifications. For example, patent CN201922264999.1 discloses a valve that can connect to multiple pipelines. This valve addresses the limitations of existing valves, most of which are unidirectional valves, meaning they have only one outlet and one inlet, allowing control in only one direction. Valves and pipelines are required for different directions, resulting in a large installation workload, significant labor requirements, resource waste, and to some extent, water wastage, reducing pipeline utilization. This valve, however, features multiple connecting pipes on the connector, allowing simultaneous connection to multiple pipelines in different directions. Each connecting pipe has an individual valve assembly, and the direction and flow rate of water can be determined based on the on / off status of each valve assembly. Furthermore, it is convenient, flexible, safe, and reliable in operation.

[0003] The above-mentioned valves have some shortcomings: during long-term use, dirt in the water will remain at the bottom of the valve, and under the force of water flow, it is easy to flow along the pipe to various places, making it impossible to switch the water supply channel and difficult to clean. Utility Model Content

[0004] The main objective of this disclosure is to provide a multi-pipe flow control valve to effectively solve the problems raised by the inventors in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multi-pipe flow control valve includes a flow control straight pipe and a flow diversion valve body. The flow control straight pipe has three inlets of the same size on its outer side, and the three inlets are arranged in a ring array. The flow control straight pipe is fixedly installed on the right inlet, and the first delivery pipe and the second delivery pipe are fixedly installed on the two inlets on the left, respectively. That is, the first delivery pipe and the second delivery pipe are symmetrically arranged. The flow diversion valve body is provided with a flow control mechanism, and the flow control mechanism cooperates with the three inlets.

[0007] Preferably, the flow control mechanism includes a central rotating shaft, a sealing sleeve, and sector valve plates. The central rotating shaft is rotatably installed inside the flow divider valve body, and a sealing sleeve is fixedly installed on the central rotating shaft. Three sector valve plates are fixedly installed on the sealing sleeve, and the three sector valve plates are tightly connected. The size of the sector valve plate is larger than the size of the inlet.

[0008] Preferably, one end of the central rotating shaft extends to the body of the diverter valve and is fixedly connected to a manual turntable, which has several operating holes.

[0009] Preferably, the front of the diversion valve body is fixedly equipped with twelve angle limiting posts arranged in a ring array, and the side of the manual turntable is provided with an movable opening, and the movable opening is provided with a connector that cooperates with the angle limiting posts.

[0010] Preferably, the connector includes a positioning horizontal shaft, a rotating buckle plate, a circular sleeve hole, and a reset torsion spring. The positioning horizontal shaft is fixedly installed inside the movable opening, the rotating buckle plate is rotatably installed on the positioning horizontal shaft, and a reset torsion spring is connected between the side of the rotating buckle plate and the inner wall of the movable opening. The positioning horizontal shaft passes through the reset torsion spring, and a circular sleeve hole is provided on the rotating buckle plate, with one of the angle limiting posts passing through the circular sleeve hole.

[0011] Preferably, the volume of the sector valve plate is one-sixth of the internal space volume of the diversion valve body.

[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0013] (i) In this application, the first conveying pipe is used as the input channel and the flow control straight pipe is used as the output channel. At this time, half of the area of ​​the rightmost sector valve plate in the diversion valve body is blocked at the left port of the flow control straight pipe, and the other two sector valve plates block the second conveying pipe. At this time, the flow rate is: the output is half of the input. The flow rate of the flow control straight pipe is controlled by the position of the sector valve plate. The central rotating shaft drives the sector valve plate to rotate at a certain angle, so that the flow control straight pipe is fully opened, and the flow rate is at its maximum at this time.

[0014] (ii) In this application, the direction of the water conveyance channel can also be switched. The second conveying pipe is used as the input end, the first conveying pipe is used as the input end, and the second conveying pipe is used as the output end. The switching is flexible and varied, and the water conveyance channel can be selected according to the needs for cleaning and maintenance. Flow control can be performed on each water conveyance channel.

[0015] (III) In this application, the manual turntable outside the central rotating shaft is used to rotate the sector valve plate. After rotating to the designated position, the rotating buckle is fastened to the corresponding angle limiting column so that the position of the manual turntable is fixed, thereby fixing the position of the sector valve plate inside the diversion valve body and preventing it from moving during use.

[0029] Specifically, one end of the central rotating shaft 5 extends to the outside of the diversion valve body 4 and is fixedly connected to a manual turntable 8, which has several operating holes.

[0030] Specifically, twelve angle limiting posts 9 arranged in a ring array are fixedly installed on the front of the diversion valve body 4, and the manual turntable 8 has an opening on its side, and a connecting piece that cooperates with the angle limiting posts 9 is provided in the opening.

[0031] Specifically, the connecting components include a positioning horizontal shaft 10, a rotating buckle plate 11, a circular sleeve hole 1101, and a reset torsion spring 12.
