A multi-channel rotary joint

Abstract

The utility model relates to the technical field of joints, specifically a multi-channel rotary joint, including a straight-through pipe, the inner side wall of the straight-through pipe is clamped with a protective component, and the protective component includes a water inlet pipe, a partition, a water hole, a connecting column, a spring, a blocking block, a clamping ring and an expansion port. The utility model is provided with a water inlet pipe, a partition, a water hole, a connecting column, a spring, a blocking block, a clamping ring and an expansion port. When in use, the fluid flows from the water inlet pipe to the partition, and then flows out from a plurality of water holes on the surface of the partition. If the water flow rate is too fast, it will drive the connecting column to slide to one side of the clamping ring.

After that, the spring rebounds and resets, so that the water flow flows again, and the water flow rate is controlled, thereby achieving the effect of improving the service life of the joint, avoiding the direct collision of the fluid with the inner wall of the joint when the hydraulic flow rate is too fast, which is easy to cause damage to the inner wall, thereby reducing the service life of the device.

Description

Technical Field

[0001] The utility model relates to the technical field of joints, in particular to a multi-channel rotary joint. Background Art

[0002] The rotary joint is a closed rotary connector that can rotate 360° to transport media. It can simultaneously transmit multiple media such as gas, liquid, oil, etc. It has the characteristics of smooth and long-lasting operation, firmness and flexibility, and low friction coefficient, and is widely used.

[0003] However, the rotary joint in the prior art still has the disadvantage that it is difficult to increase the service life of the joint. When in use, when the hydraulic flow rate is too fast, the fluid directly collides with the inner wall of the joint, which can easily cause damage to the inner wall, resulting in a reduced service life of the device. Moreover, the rotary joint in the prior art still has the disadvantage that it is difficult to adjust the water outlet direction. When in use, the water outlet direction of the joint is too fixed and difficult to adjust, resulting in limitations in the device and a result that is not conducive to use. Utility Model Content

After that, the spring 6 rebounds and resets to make the water flow again, and the water flow rate is controlled, thereby achieving the effect of improving the service life of the joint, avoiding the situation that when the hydraulic flow rate is too fast, the fluid directly collides with the inner wall of the joint, which is easy to cause damage to the inner wall, thereby reducing the service life of the device;

[0026] A main water outlet 10 is fixedly connected to one side of the surface of the straight-through pipe 1, and a water outlet assembly is threadedly connected to the inner wall of the main water outlet 10. A closing assembly is rotatably connected to the inside of the water outlet assembly. The closing assembly includes a rotating rod 11, a rotating knob 12, a sealing ring 13 and a cover plate 14. The outer surface of the rotating rod 11 is rotatably connected to the inside of the water outlet assembly.

When the main water outlet pipe 19 is connected to the main water outlet 10, the sealing gasket 20 will block the connection gap to prevent fluid leakage. The number of water outlets is increased by the setting of the auxiliary water outlet pipe 22, achieving the effect of multiple channels.
