Description

Pipe joint and its removal tool

The invention relates to a pipe fitting assembly, especially a pipe joint used for closing the end of a pipe fitting or for connecting the pipe fittings to each other.

The prior art pipe joint, as shown in Figure 9, can be used in a piping system. The piping system is connected by multiple pipe fittings or closed the ends of the pipe fittings according to the piping design, as shown in the figure, as One of the embodiments where the pipe joint is installed at the end of the pipe has a hollow body 80. In order to provide a single pipe or to provide the assembly of more than one pipe, the body 80 has at least one opening formed by the recess of the opening There is a ring seat part 801 and a joint part 802. The inner wall of the joint part 802 has internal threads. A sealing ring 81 is arranged at the position of the ring seat part 801. An assembling member 84 having an external thread and an external thread, an abutting ring 85 is penetrated therein, a restraining member 83 and a fastener 82 are combined in sequence, and the sealing member 82 is provided with There are external threads and the internal threads of the assembly 84 are combined with each other. The restraining member 83 is a hollow ring piece and has a plurality of teeth 831 that are bent and protruded toward the inside. When the assembly 84 is installed on the coupling portion 802 of the body 80, the assembly is assembled The external thread of the member 84 and the internal thread of the coupling part 802 are combined with each other, so that the sealing member 82 is pressed against the sealing ring 81. When in use, the tube 86 is inserted into the body 80 for positioning. At this time, the tube 86 is subjected to the teeth of the restraining member 83 The part 831 is positioned against and occluded to complete the assembly of the pipe joint and the pipe 86.

When the components of the pipe joint are assembled, the inner wall surface of the main body 80, the inner and outer wall surfaces of the assembly 84, and the outer wall surface of the sealing member 82 must be formed with threads. Therefore, the production and processing of each member must consume man-hours and costs, and When the components are assembled and combined, the main body 80 and the assembly 84 and between the sealing member 82 and the assembly 84 must be relatively rotated and combined with tools, so the assembly is cumbersome, inconvenient and time-consuming.

Furthermore, when it is desired to separate the pipe joint from the pipe 86, a tool must be used to push the fixing ring 85 toward the restraining member 83, so that the pushing point 832 of the outer edge of the end of the fixing ring 85 is pressed against each tooth 831. Continue to apply thrust to bend each tooth 831 to release the jamming of the pipe 86. However, since the pushing point 832 at which each tooth 831 is subjected to external force is closer to its bend, a larger external force must be used The displacement of each tooth 831 can only be reached, which is relatively inconvenient in operation and use.
