Disclosure of Invention

The invention aims to solve the technical problem of providing a gas-liquid separator for effectively fixing a U-shaped connecting pipe by using a fixing plate.

In order to solve the technical problems, the invention adopts the technical scheme that: a gas-liquid separator comprising: the inlet pipe, the outlet duct and the U-shaped connecting pipe of the barrel are arranged in, two pipes of the U-shaped connecting pipe are provided with fixing plates in clamped connection and positioned, and the fixing plates are U-shaped fixing plates formed by bending plates, and two sides of the U-shaped fixing plates are fixed with the barrel respectively.

And a solder containing groove is arranged on the fixing plate corresponding to the U-shaped pipe.

The U-shaped tail end of the fixing plate extends towards the barrel to form a bending part fixed with the barrel.

And the vertical edge of the U-shaped tail end of the fixing plate extends towards the barrel to form a bending part fixed with the barrel.

The part of the fixing plate corresponding to the U-shaped pipe is arranged into an arc surface matched with the pipe.

And a second fixing plate is arranged at the upper end of the long end part of the U-shaped connecting pipe, and a first fixing plate is arranged at the lower end of the U-shaped connecting pipe.

The bottom of the U-shaped connecting pipe is provided with a positioning hole, and a filter is fixed in the positioning hole.

The fixed plate is a U-shaped fixed plate formed by bending a plate, and two sides of the fixed plate are respectively fixed with the barrel in a brazing mode.

The outlet of the inlet pipe is lower than the height of the port of the U-shaped connecting pipe in the cylinder.

A manufacturing method of a gas-liquid separator is characterized in that a filter, a first fixing plate, a second fixing plate and a U-shaped connecting pipe are brazed in a primary furnace.

The invention has the beneficial effects that: through improving the structure of fixed plate, make filter, fixed plate one, fixed plate two and U type takeover accomplish through brazing in the stove, reduce manufacturing procedure, practice thrift the cost.

Detailed Description

The invention is described in further detail below with reference to the following figures and detailed description:

as shown in fig. 1 to 5, a gas-liquid separator includes: barrel 1, upper end cover 2, lower extreme cover 3, the import pipe 4 of arranging barrel 1 in, outlet duct 5 and U type are taken over 6, and two pipes of 6 are taken over to the U type are equipped with fixed plate joint location, and the fixed plate is the U type fixed plate that panel bent formation and both sides are fixed with the barrel respectively, correspond the U type pipe position on the fixed plate and set up the arc with tub looks adaptation. A solder receiving groove 10 is formed in the fixing plate corresponding to the U-shaped tube.

The fixed plate U-shaped end extends to the barrel 1 to form a bending part fixed with the barrel 1, or extends to the barrel 1 on the vertical edge of the fixed plate U-shaped end to form a bending part fixed with the barrel 1, and the bending part is used for being welded with the barrel and fixing the U-shaped connecting pipe.

The upper end of the long end part of the U-shaped connecting pipe 6 is provided with a second fixing plate 9, the lower end of the long end part of the U-shaped connecting pipe is provided with a first fixing plate 7, and the upper part and the lower part of the U-shaped connecting pipe are fixed to solve the problem of vibration noise.
