Problems solved by technology

In the prior art, the end face of the pipe is generally sealed and fixed by using an American-style joint combined with a rubber pad and a spring. This method has problems such as the rubber pad being scrapped quickly and the sealing not meeting the requirements, and its safety performance cannot be guaranteed. , and will cause a great waste of gas, and the material on the surface where the end of the pipe is clamped is easy to fall

Embodiment Construction

[0016] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] see figure 1 In the shown isobaric inflatable sealing joint device for cleaning the inner wall of the pipe, the pipe 1 has a central through hole 11 extending in the axial direction, and the cleaning means filling the central through hole 11 with high-pressure nitrogen gas to clean the inner wall. The isobaric pneumatic sealing joint device includes a cylinder 2, the cylinder 2 includes a cylinder 21 with an inner cavity, a first end cover 22 and a second end cover 23 fixedly arranged at both ends of the cylinder 21 respectively, The piston rod 24 in the inner chamber and the piston 25 arranged on the piston rod 24, one end of the piston rod 24 is fixed on the first end cover 22, here, the piston rod 24 and the first end cover 22 are integrally arranged, the piston 25 is at least partly sleeved on the pis...

Abstract

The invention discloses an isobaric inflatable seal joint device for cleaning the internal wall of a tube. The isobaric inflatable seal joint device is characterized in that a seal ball is arranged in a cylinder barrel of an air cylinder; the tube is arranged in a first through hole formed in the seal ball in a penetrating manner; the seal ball is extruded by a piston when the cylinder barrel is inflated; after the seal ball is extruded, a radial force is generated, so that the seal ball can be tightly pressed on the outer periphery of the tube, a tight seal is formed between the seal ball and the tube, and the tube is positioned; and at the moment, high-pressure nitrogen is filled in, and can fully enters the central through hole of the tube to clean the internal wall of the tube. The isobaric inflatable seal joint device is simple in structure and good in sealability; when the internal wall of the tube is cleaned, the gas loss is low; furthermore, as the seal ball is adopted to fix the tube in the isobaric inflatable seal joint device, the fixing place is tightly fastened and uneasy to loose, so that the safety and the stability of the device are good; in addition, the fixing place does not damage a material on the outer surface of the tube; and the isobaric inflatable seal joint device is good in usability.

Description

[0001] technical field [0002] The invention relates to an isobaric air-filled sealing joint device for cleaning the inner wall of a pipe. [0003] Background technique [0004] Some pipes need to be cleaned after a certain period of time. When cleaning, they can be flushed by filling high-pressure nitrogen into the inner cavity of the pipe. When flushing, the end of the pipe needs to be fixed to facilitate filling with high-pressure nitrogen. In the prior art, the end face of the pipe is generally sealed and fixed by using an American-style joint combined with a rubber pad and a spring. This method has problems such as the rubber pad being scrapped quickly and the sealing not meeting the requirements, and its safety performance cannot be guaranteed. , and will cause a great waste of gas, and the material on the surface where the end of the pipe is clamped is easy to fall. [0005] Contents of the invention [0006] The purpose of the present invention is to provide ...
