Tube connecting device capable of carrying out fixing and sealing simultaneously

Abstract

The invention discloses a tube connecting device capable of carrying out fixing and sealing simultaneously, and provides a device capable of carrying out fixing and sealing simultaneously. An intermediate shaft is composed of a first connecting portion and a second connecting portion, the axis of the first connecting portion and the axis of the second connecting portion are coincident, a sealed connection through hole is formed in the first connecting portion, a sealed through groove is formed in the side face of the sealed connection through hole, the sealed connection through hole and the sealed through groove are integrated, a fixed seat is arranged on the first connecting portion in a sleeved mode, and an installation through hole is formed in the fixed seat; a sealing assembly is composed of a clamp plate and a sealing gasket, the sealing assembly is installed in the installation through hole, a connecting body on the clamp plate and the portion, corresponding to the connecting body, of the sealing gasket are exposed out of the first connecting portion on the intermediate shaft and the side face of the fixed seat, and the connecting body on the clamp plate and the portion, corresponding to the connecting body, of the sealing gasket are connected through sealed connection bolts. The second connecting portion and a fastening nut are connected through threads, and a fastening gasket is arranged between the fixed seat and the fastening nut. Two connected tubes in the intermediate shaft and the fixed seat are fixed by screwing the nut, and the sealing assembly and the two tubes are sealed by screwing the bolt. The tube connecting device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of heating and ventilating, in particular to a pipe connection device capable of simultaneously realizing fixation and sealing. Background technique [0002] When installing pipelines in the HVAC field, it is often necessary to connect pipes. At present, the connection methods of pipes mainly include direct welding, flange connection, etc. The welding between different pipes requires special welding processes. Flange connection It is easy to disassemble and assemble, and flange connection also requires welding flange work. All welding work needs to be equipped with professional technicians and welding equipment, which increases the manpower and material costs of the construction site to a certain extent. Therefore, there is an urgent need for a pipe connection method that can replace pipe welding and can be fixed and sealed at the same time. Contents of the invention [0003] The object of the present inv...
