Description

Technical Field

[0001] The utility model belongs to the technical field of joints, and in particular relates to a roller rotary joint. Background Art

[0002] During the production process of industrial yarn, a large amount of high-temperature condensed water is generated. In order to save resources, the condensed water is usually pumped to the roller to heat and insulate the wire rope. The current rotary joint used to connect the pipe and the roller includes a rotating part, a connector is provided at one end of the rotating part for connecting to the roller, and a water inlet and a drain are respectively provided at the other end. Among them, the sealing spring part in the joint is located at the drain outlet, but the sealing spring is prone to scale accumulation and blockage, and it cannot be cleaned, so a new rotary joint can only be replaced, which increases the cost investment. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a roller rotary joint.

[0004] The technical solution adopted by the utility model is a roller rotary joint, comprising a connecting seat and an adapter seat, the connecting seat head end and the adapter seat tail end are connected by screws, the connecting seat tail end is provided with a water outlet, the water outlet external thread is connected to the roller thread, the adapter seat head end is provided with a water inlet, the water inlet external thread is connected to the high-pressure pipe thread, the water inlet and the water outlet are connected by a water inlet pipe, the adapter seat and the connecting seat are internally provided with a drainage channel outside the water inlet pipe, the drainage channel is connected to the drainage outlet, and the drainage outlet is provided on the side of the adapter seat; a sealing baffle is provided at the connection between the connecting seat and the adapter seat, and an elastic column is provided between the sealing baffle and the cover plate of the adapter seat head end.

[0005] Preferably, the aperture of the drain port is 1.2-1.5 times the aperture of the water inlet.

[0006] Preferably, a curved surface transition is adopted between the drain outlet and the adapter seat.

[0007] Preferably, there are 4-6 elastic columns, which are evenly arranged along the circumference of the sealing baffle and close to the inner wall surface of the adapter seat.

[0008] Compared with the existing technology, the beneficial effect of the present invention is that the rotary joint is set to be connected by screws between the connecting seat and the adapter seat, which is convenient for disassembly and cleaning, and there is no need to directly replace the joint. The elastic column replaces the original spring. While ensuring the sealing, since the elastic column is located just outside the drain outlet close to the inner wall of the adapter seat, it occupies a small volume, which solves the problem that the spring easily causes scale and impurities to accumulate and block the drain outlet, ensures smooth drainage, reduces the frequency of joint replacement, and saves costs.

[0011] The present invention will be further explained below with reference to the accompanying drawings to facilitate better understanding by those skilled in the art.

[0012] Example 1

[0013] like Figure 1-2 As shown, a roller rotary joint includes a connecting seat 1 and an adapter seat 2, the head end of the connecting seat 1 and the tail end of the adapter seat 2 are connected by screws, the tail end of the connecting seat 1 is provided with a water outlet 3, the external thread of the water outlet 3 is connected to the roller thread, the head end of the adapter seat 2 is provided with a water inlet 4, the external thread of the water inlet 4 is connected to the high-pressure pipe thread, the water inlet 4 and the water outlet 3 are connected by a water inlet pipe 5, the adapter seat 2 and the connecting seat 1 are internally provided with a drainage channel 6 located outside the water inlet pipe 5, the drainage channel 6 is connected to the drainage outlet 7, and the drainage outlet 7 is provided on the side of the adapter seat 2; a sealing baffle 8 is provided at the connection between the connecting seat 1 and the adapter seat 2, and an elastic column 10 is provided between the sealing baffle 8 and the cover plate 9 at the head end of the adapter seat 2. The rotary joint is set to be connected by screws between the connecting seat 1 and the adapter seat 2, which is convenient for disassembly and cleaning, and there is no need to directly replace the joint. The elastic column 10 is used to replace the original spring. While ensuring the sealing, since the elastic column 10 is located just outside the drain outlet 7 close to the inner wall of the adapter seat 2, it occupies a small volume, which solves the problem that the spring easily causes scale and impurities to accumulate and block the drain outlet, ensures smooth drainage, reduces the frequency of joint replacement, and saves costs.

[0014] Furthermore, the aperture of the drain port 7 is 1.2-1.5 times the aperture of the water inlet 4, which ensures drainage efficiency and is conducive to the discharge of scale impurities.

[0015] Furthermore, a curved surface transition is adopted between the drain port 7 and the adapter 2, which is conducive to the discharge of scale and avoids accumulation caused by right-angled surfaces.

[0016] There are 4 to 6 elastic columns 10, which are evenly arranged along the circumference of the sealing pad 8 and close to the inner wall of the adapter 2, ensuring elastic abutment against the sealing baffle 8 and the cover plate 9, enhancing the sealing of the joint, and occupying a small volume to avoid interference with the drain outlet.

[0017] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and improvements made by those skilled in the art to the technical solution of the present invention without departing from the spirit and principles of the present invention shall fall within the scope of protection defined by the claims of the present invention.
