Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to an adjustable rotary multi-way valve. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part after being pressurized by blowers, compressors, pumps and boilers. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

[0003] In order to change the flow direction of the internal medium, the pipeline usually needs to be connected to pipelines leading to other directions. When connecting pipelines, it is necessary to use multi-way valves such as two-way, three-way, and four-way valves to connect them, so that the medium inside the pipeline can not only be transported in reverse direction, but also be diverted.

[0004] Most of the auxiliary water outlets on multi-way pipes are fixed and cannot be adjusted after installation. If the direction is wrong when connecting the auxiliary water outlet, it is necessary to reinstall it, which wastes time. In addition, the auxiliary water outlet is fixed and has certain limitations. When connecting the hose, if the auxiliary water outlet pipe is not consistent with the direction of the hose, it is easy to cause the hose to bend and reduce the water flow rate.

The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0024] See attached Figure 1-5 As shown, the adjustable rotary multi-way valve of the first embodiment includes: a flow tube 1, and a water hole 11 which is opened in the circumferential direction of the flow tube 1 and communicates with the interior thereof; the flow tube 1 can be connected to a pipeline so that the medium inside the pipeline can enter the flow tube 1, and the water hole 11 can make the medium inside the flow tube 1 flow out, thereby preliminarily realizing the effect of medium diversion.

[0025] A movable rotary valve is provided in a sealing and rotating sleeve on the circumference of the circulation pipe 1. The movable rotary valve is arranged in cooperation with the water hole 11. Liquid enters the movable rotary valve through the water hole 11 of the circulation pipe 1 and flows out from the water outlet of the movable rotary valve.

[0026] The movable rotary valve is sleeved on the circulation pipe 1 in a sealed and rotatable manner. Since the movable rotary valve is designed to cooperate with the water hole 11, the medium inside the circulation pipe 1 can enter the movable rotary valve through the water hole 11, thereby achieving the purpose of multi-pass, so that it can produce two-way, three-way and other multi-way pipelines according to actual needs, which is convenient for fluid diversion and redirection. Since the movable rotary valve is rotatable, the water outlet direction of the movable rotary valve can be freely adjusted during installation, preventing the movable rotary valve from being difficult to connect to other pipelines due to space limitations, and avoiding the bending of the hose, thereby improving practicality.

[0027] A sealing ring 12 is provided on the circulation pipe 1 . The sealing ring 12 is located at the connection between the movable rotary valve and the circulation pipe 1 , and is used to increase the sealing performance of the connection between the movable rotary valve and the circulation pipe 1 .

[0028] The sealing rings 12 may be located on both sides of the water hole 11 , so that the medium flowing out of the water hole 11 is blocked by the sealing rings 12 to prevent leakage.

[0029] At least two sealing rings 12 are provided for respectively sealing the two sides of the water hole 11; two sealing rings 12 can just seal the two sides of the water hole 11, and more sealing rings 12 can be added to achieve multiple sealing.

[0031] The medium flowing out of the water hole 11 can first enter the water collecting tank 13 to be gathered, and then enter the movable rotary valve, so that the medium flow is more stable, and the movable rotary valve can also ensure the normal diversion of the medium during the rotation process.

[0032] Furthermore, the movable rotary valve includes at least one of a first rotary valve 2 and a second rotary valve 3, and the first rotary valve 2 and the second rotary valve 3 are respectively provided with a first water inlet groove 21 and a second water inlet groove 31 that can be connected to the water hole 11, and the first water inlet groove 21 and the second water inlet groove 31 can allow the medium inside the circulation pipe 1 to enter the first rotary valve 2 and the second rotary valve 3.

[0033] After the movable rotary valve is sleeved on the circulation pipe 1, the medium inside the circulation pipe 1 can enter the water collecting tank 13 through the water hole 11, and finally enter the movable rotary valve through the first water inlet tank 21 and the second water inlet tank 31, and finally be discharged through the water outlet of the movable rotary valve.

[0034] Furthermore, an annular groove 17 for installing the sealing ring 12 is provided on the circulation pipe 1, and the cross section of the annular groove 17 is semicircular.

[0035] The annular groove 17 can limit the position of the sealing ring 12, so that when the flow pipe 1 is inserted into the movable rotary valve, the position change of the sealing ring 12 due to friction can be avoided.

[0036] Furthermore, a connecting thread 14 is provided at one end of the circulation tube 1 , and a closing cap 15 screwed with the connecting thread 14 is provided inside the circulation tube 1 .

[0037] One end of the flow tube 1 can be closed by the closing cover 15 to make it change into a multi-pass tube. The closing cover 15 is screwed in by connecting the thread 14, and the disassembly is simple and convenient.

[0038] Furthermore, a connection flange 16 is provided at one end of the circulation pipe 1, and the connection flange 16 facilitates the circulation pipe 1 to be fixed to the medium conveying pipe.

A pin 23 for limiting the water outlet pipe 22 is movably penetrated through the first rotary valve 2. A limiting groove 24 adapted to the pin 23 is circumferentially recessed on the surface of the water outlet pipe 22.

[0040] The water outlet pipe 22 can be connected to the first water inlet groove 21 , so that the first rotary valve 2 can discharge water through the water outlet pipe 22 , and the latch 23 and the limiting groove 24 are used for limiting the water outlet pipe 22 .

[0041] Furthermore, a sealing ring 25 is sleeved on the outer annular surface of the water outlet pipe 22 inserted into the first water inlet groove 21 , and an external thread 26 is provided on the surface of the water outlet pipe 22 exposed from the first water inlet groove 21 .

[0042] The sealing ring 25 can increase the sealing and firmness between the water outlet pipe 22 and the first rotary valve 2 , thereby preventing the water outlet pipe 22 from leaking.

[0043] Furthermore, a water outlet channel communicating with the second water inlet groove 31 is provided through the second rotary valve 3 , and an internal thread 32 is provided on the inner annular surface of the water outlet channel.
