Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0027] A sealing connection method for a circular hose, involving a sleeve, a pressure sleeve and a circular hose. The hole is set in cooperation with the cone, and the method includes the following steps:

[0028] Step 1. The circular hose passes through the gland and is inserted into the sleeve;

[0029] Step 2: Move the pressure sleeve to press it tightly with the sleeve, so that the cone of the sleeve shrinks under pressure, and the section of the circular hose inside the cone is squeezed and deformed to complete the connection and sealing of the circular hose.

[0030] A sealing connection method for a square hose, involving a square hose, a connection block with a hollow quadrangular pyramid structure, and a briquetting block process...

Abstract

The invention discloses a medium and high pressure resistant self-sealing square-circle conversion joint and a sealing connection method for hoses, and relates to the technical field of sealing and connection of hoses. The sleeve and the pressing block with a rectangular hole are processed. One end of the joint body is fixed with a connecting block, and a blind hole is installed inside. The pressing block can be pressed against the joint body. The sleeve and the pressing sleeve are arranged in the blind installation hole. Compress to the sleeve; the sealing connection method of the circular hose involves the sleeve and the pressure sleeve, the hose passes through the pressure sleeve and is inserted into the sleeve, and the pressure sleeve is moved to make the cone squeeze the hose to complete the sealed connection; square The hose sealing connection method involves a connection block and a pressure block, the hose passes through the pressure block and is sleeved on the connection block, and the pressure block is moved to complete the connection and sealing of the hose under the extrusion of the connection block and the pressure block. The method is reliable in connection, does not need additional seals, and has low cost; the conversion joint has a simple structure, convenient and quick operation, and can withstand medium and high pressure loads.

Description

technical field [0001] The invention relates to the technical field of hose sealing and connection, in particular to a medium and high pressure resistant self-sealing square-to-circle conversion joint and a sealing connection method for hoses. Background technique [0002] Hose is an important part of modern industry, according to its cross-section classification, commonly used are round hose and square hose. In real life, according to their use requirements, there are equipment equipped with round hoses and equipment equipped with square hoses. If these equipment need to be connected, the round pipes and square pipes need to be connected, which requires the use of square and round conversion joints. . For pipelines whose circulating medium is liquid or gas, their sealing performance should also be considered when performing connection conversion, especially for pipelines with medium and high pressure loads. The sealing performance is particularly important for the safe and...
