Description

Technical Field

[0001] The utility model belongs to the field of heating pipe connection structures, and in particular relates to a leakage-proof heating pipe connection structure. Background Art

[0002] In order to meet the basic living needs of residents in northern my country for heating in winter, the government often uses heating pipes to transport the heat energy produced by boilers to indoor heating equipment through heat media such as steam and hot water to meet the production and living needs of residents.

[0003] At present, in order to facilitate disassembly, commonly used steam heating pipes are often connected by threaded connection. However, this connection method has gaps and poor sealing. The steam or hot water in the pipe will leak from the gaps, making the pipe heating effect poor.

[0004] Therefore, in order to solve the problem that the existing heating pipe connection structure is a threaded connection with a gap, has poor sealing, and the internal steam or hot water is easy to leak, the existing heating pipe connection structure is improved. Utility Model Content

[0005] In order to overcome the problem that the existing heating pipe connection structure is a threaded connection with poor sealing performance, internal steam or hot water is prone to leakage, resulting in poor heating effect.

[0006] The technical solution of the utility model is: a leakage-proof heating pipe connection structure, including a No. 1 pipe, a No. 2 pipe, a sealing ring, a sliding component, and a fixed component; the No. 1 pipe and the No. 2 pipe are both tubular structures formed by a polymer of heat-resistant PEX, the rear side of the No. 1 pipe is connected to the No. 2 pipe, the outer side of the No. 1 pipe is sleeved with a sealing ring, the outer side of the No. 1 pipe is provided with a sliding component for adjusting the position of the sealing ring, and the outer side of the sealing ring is sleeved with a fixed component.

[0007] Preferably, the position of the sealing ring is changed by a sliding component, and the sealing ring is sleeved on the joint between pipe No. 1 and pipe No. 2, and the sealing ring is made to fit tightly against the joint between pipe No. 1 and pipe No. 2 by a fixing component to prevent internal steam or hot water from leaking from the joint.

[0008] Preferably, a plug-in tube made of PEX is fixedly connected to the front side of pipe No. 2, and the plug-in tube is plugged into the inside of pipe No. 1. The PEX material has good heat resistance and can withstand internal steam and hot water. The plug-in tube is plugged into pipe No. 1 to connect pipe No. 1 and pipe No. 2.

[0009] Preferably, the sliding assembly includes a slide groove and a slider; a slide groove is opened on the No. 1 pipe, and an annular slider matching the slide groove is slidably connected in the slide groove. The slider slides in the slide groove to change the movement of the sealing ring bonded to one end of the slider on the outside of the No. 1 pipe.

[0010] Preferably, the sealing ring is bonded to one side of the slider, and the sealing ring is sleeved on the outside of the connection between pipe No. 1 and pipe No. 2. The sealing ring is moved to the joint between pipe No. 1 and pipe No. 2 by the slider, and the sealing ring can play a sealing role to prevent steam and hot water leakage.

[0011] Preferably, the fixing assembly includes a No. 1 fixing ring and a No. 2 fixing ring; a U-shaped No. 1 fixing ring is sleeved on the outside of the sealing ring, and a No. 2 fixing ring is arranged on the left side of the No. 1 fixing ring opposite to the No. 1 fixing ring. The No. 1 fixing ring and the No. 2 fixing ring are squeezed inwardly to make the sealing ring close to the joint of the pipeline, thereby fixing the sealing ring and the pipeline.

[0012] Preferably, the fixing assembly also includes a protective plate; the front and rear sides of the No. 1 fixing ring and the No. 2 fixing ring are fixedly connected with protective plates, which can form a barrier on the outside of the sealing ring, slow down the speed at which the sealing ring is eroded by the external environment, and extend the life of the sealing ring.

[0013] Preferably, the left side of the No. 1 fixing ring is fixedly connected with an anchor with a threaded structure, and the No. 2 fixing ring is provided with an anchor hole, the anchor is inserted into the anchor hole, and a nut is sleeved on the outer side of the anchor, which is close to the left side of the No. 2 fixing ring and matches the anchor. By tightening the nut, the No. 2 fixing ring can be moved closer to the No. 1 fixing ring. When the No. 2 fixing ring can no longer move, the fixation is completed.

[0014] Beneficial effects of the utility model:

[0015] 1. By changing the original threaded pipe connection method to plug-in, the pipes that originally needed to be screwed can be connected by plugging and unplugging, which makes disassembly and assembly more convenient. The sealing ring is sleeved at the joint between the No. 1 pipe and the No. 2 pipe, and the fixing component is used to apply force to the sealing ring so that the sealing ring is close to the outer wall of the pipe near the joint to prevent internal steam or hot water from leaking;

[0016] 2. The sealing ring is driven to move on the No. 1 pipe by moving the slider in the slide groove. By moving the position of the sealing ring, the sealing ring can be prevented from being cut off due to being too high during installation, thereby protecting the sealing ring. At the same time, the sealing ring is installed on the slider so that the sealing ring can be transported together with the No. 1 pipe. The protective plate can block the sealing ring, protect the sealing ring, and extend the service life of the sealing ring. BRIEF DESCRIPTION OF THE DRAWINGS
