Abstract
The invention discloses a falling-off prevention pipe joint, which comprises an outer pipe and an inner pipe, wherein the inner pipe is sleeved in a gland, an annular groove is arranged in the end surface of one side of the gland facing to the end head of the inner pipe, a cylindrical sealing bag is sleeved on the inner circumferential wall of the annular groove, the inner surface of the outer end of the cylindrical sealing bag is attached to the outer circumferential wall of the end head of the inner pipe, the end head of the outer pipe is also sleeved in the annular groove in a matching manner, the inner circumferential wall of the end head of the outer pipe is in sealing contact with the outer circumferential surface of the cylindrical sealing bag, and water inlet holes are uniformly arranged on the outer circumferential surface of the cylindrical sealing bag at intervals between the inner end of the gland, the end head of the inner. The invention has good sealing effect and convenient assembly and disassembly.
Description
Technical Field
The invention relates to a pipe joint capable of preventing falling off.
Background
The pipe joint in the prior art mainly has the problems of inconvenient and quick butt joint and disconnection and unsatisfactory sealing effect.
Disclosure of Invention
The invention aims to provide a pipe joint capable of preventing falling off, which not only has good sealing effect, but also is very convenient to disassemble and assemble.
The anti-falling pipe joint comprises an outer pipe and an inner pipe, wherein the inner pipe is sleeved in a gland, a circular groove is arranged in the end face of one side of the gland facing to the end head of the inner pipe, a cylindrical sealing bag is sleeved on the inner circumferential wall of the circular groove, the inner surface of the outer end of the cylindrical sealing bag is attached to the outer circumferential wall of the end head of the inner pipe, the end head of the outer pipe is also sleeved in the circular groove in a matched mode, the inner circumferential wall of the end head of the outer pipe is in sealing contact with the outer circumferential surface of the cylindrical sealing bag, and water inlet holes are formed in the outer circumferential surface of the cylindrical sealing bag between the inner end of the gland, the end head of the inner pipe and the inner circumferential wall of the outer.
After the inner pipe and the outer pipe are sleeved with each other, water and gas media in the pipe can enter the sealing bag from the water inlet hole, the automatic expansion effect of the sealing bag is enhanced, the sealing bag is automatically sealed from the left end of a gap between the gland and the inner pipe after being expanded, and the whole sealing bag achieves the function of automatic sealing. Meanwhile, the function of preventing the inner pipe from automatically falling off from the outer pipe can be achieved. When the inner tube needs to be disconnected, the inner tube is pulled out of the outer tube at the left end only after the pressure of the outer tube at the left end is closed. The gland mainly plays a role in fixing the sealing of the sealing gasket. The invention is particularly convenient and quick when being used for connecting pipelines with pressure, has better sealing effect, and can be applied to pipe joints in pipelines which frequently need to be connected and disconnected.
Drawings
The present invention will be described in further detail below with reference to the accompanying drawings.
Fig. 1 is a schematic front view of a cross-sectional structure according to the present invention.
Detailed Description
A pipe joint for preventing falling off is shown in figure 1 and comprises an outer pipe 1 and an inner pipe 5, wherein the inner pipe 5 is sleeved in a gland 4, a circular groove 6 is arranged in one side end face of the gland 4 facing to an end of the inner pipe, a cylindrical sealing bag 2 is sleeved on the inner peripheral wall of the circular groove 6, the inner surface of the outer side end of the cylindrical sealing bag 2 is attached to the outer peripheral wall of the end of the inner pipe, the end of the outer pipe 1 is also sleeved in the circular groove 6 in a matched mode, the inner peripheral wall of the end of the outer pipe 1 is in sealing contact with the outer peripheral surface of the cylindrical sealing bag 2, and water inlet holes 3 are uniformly arranged on the outer peripheral surface of the cylindrical sealing bag 2 between the inner side end of the gland 4, the end of the inner pipe 5 and the inner. After the inner pipe 5 and the outer pipe 1 are sleeved with each other, water and gas media in the pipe can enter the sealing bag 2 from the water inlet hole, the automatic expansion effect of the sealing bag 2 is enhanced, the sealing bag 2 is automatically sealed from the left end of the gap between the gland 4 and the inner pipe 5 after being expanded, and the whole sealing bag achieves the function of automatic sealing. Meanwhile, the function of preventing the inner pipe from automatically falling off from the outer pipe can be achieved.
