Description

Technical Field

[0001] This utility model belongs to the field of irrigation valve technology, specifically relating to a multi-channel valve assembly. Background Technology

[0002] Farmland irrigation requires water valves to control the water supply pipeline. These valves can be used as pipe joints to connect to faucets or other water-using equipment. Once buried, they do not need to be removed. The branch line supplying water can be opened as needed for irrigation. The conventional valve core is a ball-shaped valve core with a through hole. However, the fit between the outer surface of the integral ball core and the inner wall of the valve body needs to be precise to ensure water sealing. The ball surface of the valve core is difficult to manufacture and not easy to fit for sealing. After repeated use, water leakage is likely to occur at the mating surface between the ball core and the inner wall of the valve body.

[0003] Butterfly valves are controlled by a sealing plate, but they can only control one pipe and cannot selectively control the on / off state of multiple pipes, thus limiting their ease of use.

[0004] Therefore, how to provide a new type of multi-channel valve assembly with better sealing effect is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a multi-channel valve assembly with better sealing effect and flexible control pipeline.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-channel valve assembly, comprising: A multi-port pipe, wherein a valve body is integrally formed on any channel of the multi-port pipe, and a pipe interface is provided on one side of the outer wall of the valve body; A valve core is rotatably connected to the central axis of the valve body, and a spherical crown is provided on one side of the valve core; A flange joint, wherein the flange joint is fixedly connected to the pipe interface of the valve body, and a step is provided on the inner side of the end of the flange joint near the valve body; A sealing gasket is connected to the step. The sealing gasket seals against the spherical crown surface of the valve core and can block the passage between the corresponding channel and the flange joint. When the valve core blocks the passage, the spherical crown tends to move towards the sealing gasket and the flange joint based on the water supply pressure inside the multi-way pipe. The beneficial technical effects of this utility model are as follows: the multi-port pipe, used in conjunction with the valve body and valve core, provides the possibility of controlling the on / off of multiple passages separately. The flange joint is used for external pipes or accessories, and its connection to the pipe interface of the valve body is detachable, making assembly and installation more convenient. At the same time, based on the cooperation between the valve core ball crown and the sealing gasket, the passage can be sealed off. It can be understood that, based on the internal pressure of the pipe body, the ball crown tends to move towards the sealing gasket and flange joint, making the seal tighter and less prone to leakage.

[0007] Preferably, the step is provided with an annular groove, the sealing gasket is embedded in the annular groove, and the sealing gasket is provided with an arc-shaped surface that matches the spherical crown.

[0008] The resulting technical effect is that the sealing gasket has a ring-shaped structure, which is fixed to the step by an annular groove, and the sealing gasket is sealed by its arc-shaped surface against the spherical crown surface.

[0009] Preferably, it further includes a gasket, the gasket being annular and disposed on the outer side of the step near the sealing gasket, the gasket being detachably connected to the sealing gasket.

[0010] The resulting technical effect is that the gasket is used to assist in supporting the deformation of the sealing gasket, thereby ensuring the sealing effect when the sealing gasket mates with the spherical crown.

[0011] Preferably, the outer circumferential ring of the sealing gasket has a flange, the flange has a T-shaped structure, the gasket has a U-shaped structure, and the gasket is engaged with the sealing gasket.

[0012] The resulting technical effect is that the sealing gasket and the gasket have a concave-convex interlocking design, making the connection more convenient.

[0013] Preferably, the center of the arc surface of the spherical crown is provided with a material-saving blind groove.

[0014] The resulting technical effect is that the material-saving blind groove can reduce the material used in the valve core, specifically by molding it from plastic, further saving costs.

[0015] Preferably, the multi-port pipe is a four-port pipe, and the valve body has two sets and is installed on any two channels of the pipe body.

[0016] The resulting technical effect is that multiple sets of valve bodies can achieve separate control of multiple channels.

[0017] Preferably, the flange joint is used to connect to external water pipes or hoses.

[0018] The resulting technical effect is that, in practical use, the flange joint can be directly connected to a water hose or water pipe. Attached Figure Description

[0022] See appendix to this utility model Figures 1 to 5 According to an embodiment of the present invention, a multi-channel valve assembly includes: A multi-port pipe 1, and a valve body 2 integrally formed on any channel pipe body corresponding to the multi-port pipe 1, with a pipe interface 21 provided on one side of the outer wall of the valve body 2; Valve core 3 is rotatably connected to the central axis of valve body 2. The top of valve core 3 is provided with a screw head that extends out of the outer side of valve body for easy operation by the operator. A ball crown 31 is provided on one side of valve core. Flange connector 4 is a pipe interface that is fixedly connected to valve body 2. Specifically, it is a plastic part and is fixed by heat fusion to improve sealing. Flange connector 4 has a step 41 on the inner side of the end near valve body 2. The sealing gasket 5 is connected to the step 41. The sealing gasket 5 seals against the spherical crown surface of the valve core 3 and can block the passage between the corresponding channel and the flange joint 4. When the valve core 3 blocks the passage, based on the water supply pressure inside the multi-way pipe, the spherical crown tends to move towards the sealing gasket 5 and the flange joint 4. This makes the spherical crown seal more tightly. It can be understood that the increase in water supply pressure simultaneously improves the sealing force and sealing effect. In other embodiments, the step 41 is provided with an annular groove 42, the sealing gasket 5 is a rubber ring, which is embedded in the annular groove 42, and the sealing gasket 5 is provided with an arc-shaped surface 52 that matches the spherical crown 31.

[0027] In some other specific embodiments, the flange connector 4 is used to connect an external water pipe or hose.

[0028] Specific control process: When the spherical crown of the valve core corresponds to the pipe interface, the arc surface of the spherical crown is in close contact with the sealing gasket, thus sealing the corresponding pipe interface. When multiple water circuits need to be controlled, the valve core of the corresponding circuit can be operated.
