Abstract

A liquid-vapor separator comprises a tank body, wherein the bottom of the tank body is fixedly provided with a base, the upper end face of the tank body is provided with a coolant inlet pipe and a coolant outlet pipe which penetrate through the upper end face of the tank body along the axis of the tank body, the coolant outlet pipe is a U-shaped pipe, one end of the coolant outlet pipe is positioned on the upper part in the tank body, the coolant inlet pipe extends to the lower part of the side of the end port of the coolant outlet pipe in the tank body, and the lower part of the coolant outlet pipe in the tank body is provided with an oil return hole penetrating through the side wall of the coolant outlet pipe, and the upper part of the coolant outlet pipe in the tank body is also provided with a balance hole penetrating through the side wall of the coolant outlet pipe. The utility model has small size, high efficiency of liquid-vapor separation and good effect of oil return.

Description

A kind of gas-liquid separator

Technical field

The utility model relates to a kind of gas-liquid separator, the gas-liquid separator that uses in specifically a kind of refrigeration system.

Background technology

At present, the gas-liquid separator that adopts on the air-conditioning equipment normally is made up of parts such as housing, end socket, straight tubes, gas-liquid mixture is entered by position, middle and upper part, housing side, through Gravity Separation gas and fluid separation applications are come, this kind method separation rate is low, still has the operative liquid refrigerant to be sucked by compressor and enters compressor inside, because liquid refrigerants does not have compressibility, therefore occur " liquid hammer " phenomenon easily, damage compressor.

The utility model content

The technical problems to be solved in the utility model provides the high gas-liquid separator of a kind of gas-liquid separation efficient.

In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:

A kind of gas-liquid separator comprises tank body, and the tank body bottom surface is installed with base, is provided with refrigerant inlet tube and the refrigerant exit pipe that runs through the tank body upper surface at upper edge, tank body upper surface tank body axis.Described refrigerant exit pipe is the U-shaped pipe, and this refrigerant exit Guan Yiduan is positioned at the tank body internal upper part, and the refrigerant inlet tube extends to the side-lower of the refrigerant exit pipe port that is positioned at tank body.

As the improvement to such scheme, the refrigerant exit pipe bottom in tank body offers the spill port that runs through refrigerant exit pipe sidewall.

As further improvement of these options, the refrigerant exit pipe top in tank body offers the balance pipe that runs through refrigerant exit pipe sidewall.

The utility model volume is little, easy for installation, be used between refrigeration system evaporimeter and the compressor, gas-liquid separation efficient height, and on the refrigerant exit pipe, be provided with spill port and balance pipe, lubricating oil is got back in the compressor, prolonged the service life of compressor, the balance pipe active balance the inside and outside pressure of refrigerant exit pipe, prolong life-span of refrigerant exit pipe.

Description of drawings

Accompanying drawing 1 is a cross-sectional view of the present utility model; Accompanying drawing the utility model cross section structure schematic diagram.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model is further described below in conjunction with specific embodiment and accompanying drawing:

Shown in accompanying drawing 1,2, a kind of gas-liquid separator comprises tank body 1, and tank body 1 bottom surface is installed with base 2, upper edge, tank body 1 upper surface tank body 1 axis be provided with run through tank body 1 upper surface refrigerant inlet tube 3 and refrigerant exit pipe 4.Described refrigerant exit pipe 4 is the U-shaped pipe, these refrigerant exit pipe 4 one ends are positioned at tank body 1 internal upper part, refrigerant inlet tube 3 extends to the side-lower of refrigerant exit pipe 4 ports that are positioned at tank body 1, and the mixture of avoiding containing liquid state and gaseous coolant directly enters U-shaped refrigerant exit pipe 4 in refrigerant inlet tube 3 enters tank body 1 time.Refrigerant exit pipe 4 bottoms that are positioned at tank body 1 are provided with the spill port 5 that runs through refrigerant exit pipe 4 sidewalls; In addition, refrigerant exit pipe 4 tops in tank body 1 are provided with the balance pipe 6 that runs through refrigerant exit pipe 4 sidewalls.

The utility model is used for refrigeration system evaporimeter and compressor chamber, during use, the mixing refrigerant that contains liquid state and gaseous state enters in the tank body 1 from refrigerant inlet tube 3 of the present utility model, liquid refrigerants flows into tank body 1 inner bottom part, gaseous coolant floats on tank body 1 internal upper part, because the getter action of compressor, gaseous coolant enters U-shaped refrigerant exit pipe 4, contain lubricating oil in the liquid refrigerants of inflow tank body 1 inner bottom part, the spill port 6 of lubricating oil through being located at refrigerant exit pipe 4 bottoms enters refrigerant exit pipe 4, and the lubricating oil and the gaseous coolant that enter refrigerant exit pipe 4 together are inhaled in the compressor.In addition, 6 pairs of refrigerant exit pipes of balance pipe, the 4 inside and outside pressure differentials of being located on the refrigerant exit pipe 4 play good balanced action, make refrigerant exit pipe 4 not fragile.

The foregoing description is the preferable implementation of the utility model, and in addition, the utility model can also other modes realize, in any conspicuous replacement under the prerequisite that does not break away from inventive concept of the present utility model all within protection domain of the present utility model.
