Sealing device for end parts of pipe

Abstract

The invention relates to the field of pressure measurement of a pipe and more specifically, relates to a sealing device for end parts of a pipe. The sealing device includes a sealing-end sealing body and an air-inlet-end sealing body, which are respectively installed at the end parts at the two ends of the pipe. One end of the sealing-end sealing body is provided with an opening and the two ends of the air-inlet-end sealing body are provided with openings. Both the sealing-end sealing body and the air-inlet-end sealing body are hollow cavities inside. Sealing rings and spring sleeve clamping tools which allow the pipe to penetrate are installed in the hollow cavities. Clamping wrenches contacting with the spring sleeve clamping tools are installed at the outer sides of the sealing-end sealing body and the air-inlet-end sealing body. The spring sleeve clamping tools can be squeezed through wrenching the clamping wrenches and deformed so as to lock the pipe which penetrates the spring sleeve clamping tools. End-part sealing heads are arranged at one opening end of the sealing-end sealing body and one opening end of the air-inlet-end sealing body. After the sealing device for the end parts of the pipe is assembled, the two ends of the pipe are inserted directly into the sealing-end sealing body and the air-inlet-end sealing body and the clamping wrenches are wrenched so that installation is completed. The sealing device is convenient to install and the installation is high in speed and efficiency.

Description

technical field [0001] The invention relates to the field of pipe pressure measurement, and more particularly relates to a pipe end sealing device. Background technique [0002] After the existing PE pipes are manufactured, the whole bundle of PE pipes needs to be packaged and packaged, and then the pressure measurement of the whole bundle of PE pipes is carried out. Commonly used end sealing joints, each part of the end sealing joint must be disassembled during installation, the sealing ring is put on the PE pipe, and then each part of the end sealing joint is assembled to lock the screw. Finally, measure the internal air pressure. During the installation process, it takes too long to assemble the various parts, the installation and test speed is slow, and each test requires disassembly and assembly again, which affects the sealing and loss of the end seal. The application of this end sealing body is labor-intensive and time-consuming, and there is also air leakage during...
