Sealed water pipe connecting mechanism

Abstract

The invention discloses a sealed water pipe connecting mechanism. The sealed water pipe connecting mechanism comprises a water pipe joint; a metal embedding pipe is fixedly arranged in a water pipe positioning hole of the water pipe joint in a sleeving mode; an internal screw thread is disposed on the inner wall of the metal embedding pipe. The sealed water pipe connecting mechanism is characterized in that the water pipe positioning hole is a stepped hole; the inner diameter of a small hole of the stepped hole is smaller than that of the metal embedding pipe to form a sealed step; a seal ring is disposed on the inner wall of the upper end port of the metal embedding pipe; the inner diameter of the upper end of the seal ring is equal to that of the internal screw thread; the inner diameter of the lower end of the seal ring is smaller than that of the internal screw thread; the inner diameter of the seal ring is in smooth transition from bottom to top. The sealed water pipe connecting mechanism has the beneficial effects that the structure is simple; dismounting is convenient; multiple sealing between the metal embedding pipe and the pipe joint and between the metal embedding pipe and an external pipe is achieved; the sealing effect is greatly improved; meanwhile, the anti-seismic property of the pipe connecting structure is improved.

Description

technical field [0001] The invention belongs to the technical field of connecting pipe structures, and in particular relates to a sealed water pipe connecting mechanism. Background technique [0002] The connection between the water pipe and the water pipe joint is generally formed by melting the connection part with a hot melter and then combining it at high temperature or through threaded connection. However, if the water pipe connected by the hot melter is not installed properly, the connection will not be sealed and leak. Moreover, the water pipes connected in this way are not easy to disassemble and repair; the water pipe joints connected by thread fit need to use metal embedded pipes, but the existing metal embedded pipes have poor sealing performance, and water is easy to leak from the seams. [0003] Disadvantages of the existing technology: the connection between the water pipe and the water pipe joint is not well sealed, and the water pipe connected through the fus...

[0002] The connection between the water pipe and the water pipe joint is generally formed by melting the connection part with a hot melter and then combining it at high temperature or through threaded connection. However, if the water pipe connected by the hot melter is not installed properly, the connection will not be sealed and leak. Moreover, the water pipes connected in this way are not easy to disassemble and repair; the water pipe joints connected by thread fit need to use metal embedded pipes, but the existing metal embedded pipes are not well sealed, and water is easy to leak from the seams

[0003] Disadvantages of the existing technology: the connection between the water pipe and the water pipe joint is not well sealed, and the water pipe connected through the fuser leaks and it is inconvenient to disassemble and repair; the water pipe connected by the metal embedded pipe is easy to leak from the seam, and the joint is easy to be damaged. Loosening occurs under the influence of shaking, and the seismic performance is poor
