Description

Technical Field

[0001] This utility model relates to the field of sealing devices, and more particularly to pipe joint sealing devices. Background Technology

[0002] Pipe joint sealing devices, also known as sealing joints, are mainly used to ensure the sealing performance of pipe connections and prevent fluid leakage and gas infiltration. They are an indispensable and important component of pipeline systems and are crucial for improving the safety and stability of pipeline systems.

[0003] Existing pipe joint sealing devices have a relatively simple structure. During the operation of the pipeline system, vibration and impact may cause the sealing device to loosen or be damaged, resulting in leakage. In addition, the pipeline is affected by environmental factors such as temperature and pressure, and is subject to thermal expansion and contraction. Over time, it is prone to deformation and twisting, which affects the sealing performance.

[0004] Therefore, to address the problems of leakage, thermal expansion and contraction deformation, and distortion affecting the sealing performance of existing pipe joint sealing devices caused by vibration and impact, a pipe joint sealing device can be designed. The sealing connecting ring seals and fixes the two pipe bodies, and the clamping plate clamps and fixes the pipe body under the elastic force of the spring. This multiple sealing fixation is simple to operate, easy to disassemble and assemble, and improves stability and sealing performance. Utility Model Content

A protective cover is fixedly connected to the upper end of the mounting base, and a sealing connecting ring is fixedly connected inside the protective cover. Two pipe bodies are movably connected inside the sealing connecting ring. Lower fixed seats are symmetrically connected to both the left and right ends of the mounting base. An upper fixed seat is rotatably connected to the rear end of the lower fixed seat via a rotating shaft. A spring is fixedly connected to the end of the lower fixed seat and the upper fixed seat near the pipe body. A clamping plate is fixedly connected to the end of the spring near the pipe body. The front ends of the lower fixed seat and the upper fixed seat are connected by locking bolts.

[0007] Preferably, the pipe body is placed on the lower fixed seat, and the pipe body is pushed so that one end is inserted into the sealing connection ring. The sealing connection ring seals and fixes the two pipe bodies. The upper fixed seat closes to the lower fixed seat downward through the rotating shaft. The clamping plate clamps and fixes the pipe body under the elastic force of the spring, so as to avoid the sealing performance being affected by thermal expansion and contraction. The lower fixed seat and the upper fixed seat are locked by locking bolts.

[0008] Preferably, a sealing ring is fixedly connected to the middle of the inner wall of the sealing connecting ring, and annular limiting cavities are symmetrically opened on the inner wall of the sealing connecting ring at both ends of the sealing ring. Two sets of mounting cavities are symmetrically opened at the front and rear ends of the inner wall of the sealing connecting ring, and two mounting cavities are symmetrically arranged in each set above and below. Each set of mounting cavities is connected to the corresponding annular limiting cavity.

[0009] Preferably, two sets of limiting protrusions are fixedly connected to both the front and rear ends of the outer side of the pipe body. Each set of limiting protrusions has two symmetrically arranged protrusions, which are adapted to the annular limiting cavity and the installation cavity, respectively.

[0010] Preferably, three springs are provided, and a telescopic rod is sleeved inside each spring. The clamping plate is connected to both the lower and upper fixed seats via the telescopic rod.

[0011] Preferably, three clamping plates are arranged in an arc shape, and a rubber anti-slip pad is fixedly connected to one end of the clamping plate near the pipe body. The clamping surface of the rubber anti-slip pad is evenly provided with anti-slip protrusions.

[0013] Preferably, a sealing strip is fixedly connected to one end of the upper fixing seat near the protective cover, and the sealing strip is adapted to the left and right sides of the upper end of the protective cover.

[0014] The beneficial effects of this utility model are:

[0015] This pipe joint sealing device uses a sealing ring and a clamping plate to place the pipe body on the lower fixed seat. Pushing the pipe body so that one end is inserted into the sealing ring, the sealing ring seals and fixes the two pipe bodies, resulting in a good sealing effect. The upper fixed seat closes to the lower fixed seat via a rotating shaft. The clamping plate, under the elastic force of a spring, clamps and fixes the pipe body, preventing thermal expansion and contraction from affecting the sealing performance. Locking bolts further enhance the sealing performance by securing the lower and upper fixed seats, maintaining the connection stability of the pipe body, reducing vibration, and providing multiple sealing fixations. It is simple to operate, easy to assemble and disassemble, and improves stability and sealing performance. Attached Figure Description

Each set of mounting cavities 12 has two symmetrically arranged vertically. Each set of mounting cavities 12 is connected to the corresponding annular limiting cavity 11. The two pipe bodies 4 compress the sealing ring 10, increasing the sealing performance. The annular limiting cavity 11 facilitates installation and improves the ease of connection. Two sets of limiting protrusions are fixedly connected to the front and rear ends of the outer side of the pipe body 4. Two limiting protrusions 13 are symmetrically arranged in each group. The limiting protrusions 13 are adapted to the annular limiting cavity 11 and the installation cavity 12 respectively. The limiting protrusions 13 on the pipe body 4 enter the annular limiting cavity 11 along the installation cavity 12. When the pipe body 4 is rotated, the limiting protrusions 13 rotate along the annular limiting cavity 11 to complete the connection and fixation.
