Pipeline connecting device with high sealing performance

Abstract

The invention discloses a pipeline connecting device with high sealing performance, which comprises a pressure ring, the inner side of the pressure ring is connected with a connecting pipeline, the connecting pipeline is internally provided with a fixing device, the fixing device is internally provided with a control panel, the pressure ring is provided with a sealing groove, and the pressure ring is provided with a sealing groove. Two sets of stop blocks of the pipeline connecting device with the high sealing performance are fixed to one side of the control panel, a transmission device of the pipeline connecting device with the high sealing performance is fixed to the other side of the control panel, and a dismounting device of the pipeline connecting device with the high sealing performance is fixed to the other end of the transmission device. A blocking rod is arranged in the connecting pipeline, the blocking rod penetrates through the connecting pipeline, the blocking rod is in sliding connection with the connecting pipeline, a reset spring is welded to the other end of the blocking rod, and the other end of the reset spring is welded to the connecting pipeline.

Description

technical field [0001] The invention relates to the technical field of connecting devices, in particular to a pipeline connecting device with strong sealing performance. Background technique [0002] In the transmission pipeline, the pipeline connection device is an indispensable connection method. The traditional pipe connection method is to process external threads on the outer diameter of the pipe connection end so as to cooperate with the internal threads of the pipe joints. This connection method needs to process external threads at the pipe connection end. Since the threads have a certain depth, in order to ensure that the pipes can meet the requirements of strength and sealing performance after connection, the pipes need to have a certain wall thickness, resulting in waste of materials. At present, there is another clamping connection method. The pipe is inserted into the socket of the pipe fitting, and then a special tool is used to apply pressure from the raised pa...

Problems solved by technology

This connection method needs to process external threads at the pipe connection end. Since the threads have a certain depth, in order to ensure that the pipes can meet the requirements of strength and sealing performance after connection, the pipes need to have a certain wall thickness, resulting in material waste.

At present, there is another clamping connection method. The pipe is inserted into the socket of the pipe fitting, and then a special tool is used to apply pressure from the raised part of the socket of the pipe fitting, and the pipe and the pipe fitting are clamped to the deformed connection with hydraulic pliers. If the clamping connection is not in place, it must be Cutting pipes and replacing them with new ones is time-consuming and wastes pipes and fittings

The above two connection methods are troublesome to connect, the sealing effect is poor, and the maintenance is very inconvenient

[0003] However, the existing pipeline connection device is poor in practicability; at the same time, the installation steps of the existing pipeline connection device are cumbersome, and after the installation is completed, the internal pressure is high, and the damage to the connected parts is large
