Heating pipeline loose joint

Abstract

The utility model relates to a heating pipeline loose joint which comprises a water outlet pipe, a non-return ring, an inner pin cylinder, an outer pipe hoop, an inner pipe hoop, a water inlet pipe and a convex ring. As the inner diameter of the inner pin cylinder is larger than that of the existing loose joint, the flow of water passing through the loose joint is much larger than that of the existing loose joint; due to the fact that the rear end of the inner pin barrel is matched with the inner pipe hoop, the outer pipe hoop and the inner pipe hoop are continuously screwed through threads, the inner pin barrel is continuously pushed into the water outlet pipe under the pressure of screwing-in of the threads of the outer pipe hoop, the water outlet pipe is stressed to begin to expand, the water outlet pipe is locked by a convex ring of a non-return ring, and the water outlet pipe is not prone to slipping. A sealing ring is placed in the outer pipe hoop and can play a role in sealing the upper face and the lower face. As the water flow in the water pipe is increased, the deposition of dirt in the pipe can be reduced; the structure is simplified, installation is convenient, and cleaning, dismounting and mounting can be completed only through a common wrench in installation and later use; when the pipeline is cleaned, the problem that the projectile is clamped can be solved.

Description

Technical Field

[0001] The utility model relates to the technical field of heating pipe fittings, in particular to a heating pipeline flexible joint. Background Art

[0002] Live joints are necessary in heating pipes for civil heating. They are used to connect hoses and hoses, and hoses to water diverter valves. The existing live joints in heating pipes have a small inner diameter. After water flows through the live joints, the water flow rate is greatly reduced, resulting in substandard heating and insufficient heat. In particular, in old residential areas, due to obsolete pipes, heating cannot be operated at high pressure, otherwise there may be a risk of pipe bursting. Therefore, the room temperature can only be effectively increased by increasing the water flow rate under low-pressure operation conditions. In some small-sized units, there are few manifold branches, and more heat can only be brought in by increasing the flow rate. Summary of the invention

[0003] The purpose of the utility model is to provide a heating pipe joint. In view of the above-mentioned drawbacks, the inner diameter of the heating pipe joint is increased, the flow rate of water is reduced slightly after passing through the joint, and it is ensured that the flow rate of water in the pipeline is unobstructed when passing through the joint valve, so as to achieve the best effect. The structure is simple and maintenance is convenient.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a heating pipe joint, comprising: a water outlet pipe, a check ring, an inner pin barrel, an outer pipe clamp, an inner pipe clamp, a water inlet pipe and a convex ring, a convex ring is arranged on the inner wall of the check ring, the water outlet pipe is inserted into the check ring from one end where the convex ring is arranged, and the inner pin barrel is inserted into the water outlet pipe from the other end of the check ring, the outer diameter of the inner pin barrel is slightly larger than the inner diameter of the water outlet pipe, the front end of the inner pin barrel is conical with a certain inclination, the rear end of the inner pin barrel is matched with the inner pipe clamp, one side of the outer pipe clamp is sleeved on the outside of the check ring, and the other side is matched with the thread of the inner pipe clamp, and the inner thread of the other end of the inner pipe clamp is connected with the water inlet pipe.

[0005] A sealing ring is arranged inside the outer pipe hoop, which plays a sealing role when the outer pipe hoop is connected to the inner pipe hoop.

[0006] The internal thread at the other end of the inner pipe clamp is connected to the water distributor joint.

[0007] One side of the outer hoop is sleeved on the outside of the check ring, and the internal thread of the other end is connected with the water distributor joint.

[0008] The utility model is provided with an inner pin barrel, and the inner diameter of the inner pin barrel is larger than the inner diameter of the existing flexible joint, so the water flow through the utility model is much larger than the water flow of the existing flexible joint; because the rear end of the inner pin barrel is adapted to the inner pipe hoop, the outer pipe hoop and the inner pipe hoop are continuously tightened through the thread, and at this time, under the pressure of the outer pipe hoop thread, the inner pin barrel is continuously pushed into the outlet pipe, so that the outlet pipe begins to expand under force and enters the convex ring, and the convex ring of the check ring locks the outlet pipe, and the outlet pipe is not easy to slip off; a sealing ring is placed in the outer pipe hoop, and the sealing ring can play a sealing role on both the upper and lower sides, that is, the flexible joint interface is sealed. The utility model can reduce the deposition of dirt in the pipe by increasing the water flow in the water pipe; the structure is simplified, and it is easy to install. Only an ordinary wrench is needed to complete the operation during installation and later cleaning and disassembly; when cleaning the pipeline, the application of the utility model can solve the problem of projectile jamming.

[0021] As shown in the figure, the utility model is a heating pipe joint, comprising: an outlet pipe 1, a check ring 2, an inner pin barrel 3, an outer pipe clamp 4, an inner pipe clamp 6, a water inlet pipe 7 and a convex ring 8. The convex ring 8 is arranged on the inner wall of the check ring 2, the outlet pipe 1 is inserted into the check ring from one end where the convex ring is arranged, and the inner pin barrel 3 is inserted into the outlet pipe from the other end of the check ring. The outer diameter of the inner pin barrel is slightly larger than the inner diameter of the outlet pipe, and the front port of the inner pin barrel is conical with a certain inclination. The rear end of the inner pin barrel is matched with the inner pipe clamp 6. One side of the outer pipe clamp 4 is sleeved on the outside of the check ring, and the other side is threadably matched with the inner pipe clamp 6. The inner thread of the other end of the inner pipe clamp is connected with the water inlet pipe 7.

[0022] A sealing ring 5 is arranged inside the outer pipe hoop, which plays a sealing role when the outer pipe hoop is connected to the inner pipe hoop.

[0023] The internal thread at the other end of the inner pipe clamp is connected to the water distributor joint.

[0024] One side of the outer pipe clamp 4 is sleeved on the outside of the check ring, and the internal thread of the other end is connected to the water distributor joint.

[0025] The installation process of the utility model is as follows: first, the outer pipe clamp is put on the outlet pipe, the outlet pipe is inserted into the check ring from one end where the convex ring is set, and the inner pin barrel is inserted into the outlet pipe from the other end of the check ring. The outer diameter of the inner pin barrel is slightly larger than the inner diameter of the outlet pipe, and the front port of the inner pin barrel is conical with a certain slope. The rear end of the inner pin barrel is adapted to the inner pipe clamp, and the outer pipe clamp and the inner pipe clamp are continuously tightened through the thread. At this time, under the pressure of the outer pipe clamp thread, the inner pin barrel is continuously pushed into the outlet pipe, so that the outlet pipe begins to expand under the force and enters the convex ring. The convex ring of the check ring locks the outlet pipe, and the outlet pipe is not easy to slip off; put the sealing ring in the outer pipe clamp, tighten the outer pipe clamp and the inner pipe clamp to complete the installation. The sealing ring can play a sealing role on the upper and lower sides, that is, seal the flexible joint. The utility model is simple and convenient, labor-saving and labor-saving, and does not require special tools.

[0026] advantage:

[0027] 1. The water flow rate through the utility model is much greater than the water flow rate of the existing live joint.

The outer diameter of the inner pin barrel of the utility model is set to be about 17 mm and the inner diameter is about 15 mm, while the ordinary inner diameter of the existing live joint is 9 mm, and the inner diameter of the large flow is only 12 mm;

[0028] 2. During the heating period, the greater the pressure in the pipeline, the more outward expansion force will be generated, which will make the connection between the outlet pipe and the check ring tighter;

[0029] 3. By changing the pipe fitting data, it can adapt to various material interfaces, such as ppr, pe-rt, pb, pe and other pipes;

[0030] 4. Increase the flow rate in the water pipe and reduce the deposition of dirt in the pipe;

[0031] 5. Simplified structure, easy to install, installation and later cleaning and disassembly can be completed with just an ordinary wrench;

[0032] 6. When cleaning the pipeline, the utility model can solve the problem of projectile jamming;

[0033] 7. The utility model can be used for connecting between hoses, and can also be used for connecting between a hose and a hard pipe, such as connecting with a water distributor.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical solution and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
