Abstract

The utility model discloses a novel gas-liquid separator, which belongs to the field of air-conditioning devices and comprises a cylinder body, wherein a gas branch inlet pipe is arranged at the top of the cylinder body; a U-shaped pipe is arranged in the cylinder body; one end of the U-shaped pipe passes out of the top of the cylinder body to form the gas branch outlet pipe; the U-shaped pipe which is arranged inside the cylinder body and close to the gas branch outlet pipe is provided with a pressure-equalizing hole; and a pipeline communicated with an air sucking port of a compressor is arranged at the bottom of the cylinder body. An air-conditioning system adopting the gas-liquid separator only needs to replace a component of the gas-liquid separator without replacing the whole gas-liquid separator and wasting compressor oil when the oil return is abnormal, so that the cost of materials can be saved.

Description

A kind of novel gas-liquid separator
Technical field
The utility model relates to a kind of aircondition, relates in particular to the gas-liquid separator that a kind of air-conditioning uses.
Background technology
Gas-liquid separator is the vitals of air-conditioning system.Traditional gas-liquid separator mainly comprises cylindrical shell, is provided with gas subentry, U type pipe, gas in the cylindrical shell and divides outlet, balancing orifice and spill port.During compressor operating, refrigerant is drawn into inner barrel by the gas subentry, carry out gas-liquid separation, compressor oil separation then, gaseous coolant sucks compressor through balancing orifice, U type pipe, and isolated liquid refrigerants and compressor oil divide outlet to be drawn into compressor by spill port through U type Guan Congqi.When spill port was excessive, air-conditioning system started after long-time the shutdown, excessive liquid refrigerants flowed into compressor suction duct through spill port when cross valve commutated, and this moment, compressor had the danger of liquid hammer, thereby influenced lifetime of system; When spill port is too small, the compressor oil of separating in the gas-liquid separator can not in time flow into compressor suction duct through spill port, can accumulate too much compressor oil in the gas-liquid separator bottom behind the long-play, compressor can not get enough oil lubricatings, and oil starvation running meeting causes fatal destruction to compressor for a long time.When offering the gas-liquid separator spill port often according to forefathers' experience and to type newly developed a large amount of experiments confirm.Off size in good time when spill port in test, adopt the air-conditioning system of traditional gas-liquid separator to need the recovery system refrigerant, gas-liquid separator is changed in welding again; The volume of traditional in addition gas-liquid separator at the following position of spill port is invalid volume, increased product cost, after system's operation, can assemble compressor oil herein simultaneously, if more ventilation divides, the compressor oil that accumulates in herein can be wasted, thereby the compressor oil mass can reduce in the system, has influence on follow-up test, even can have influence on system's control constant.
The utility model content
The purpose of this utility model is to provide a kind of novel gas-liquid separator.The air-conditioning system that adopts this gas-liquid separator only need be changed parts of gas-liquid separator, and not need to change whole gas-liquid separator, and not waste compressor oil when oil return is undesired, has saved material cost.
The utility model for achieving the above object, the technical solution that adopts is: a kind of novel gas-liquid separator, comprise cylindrical shell, the top of cylindrical shell is provided with gas subentry pipe, be provided with U type pipe in the cylindrical shell, one end of U type pipe passes from the top of cylindrical shell and forms gas and divide outlet, in inner barrel, offer balancing orifice near on the U type pipe in gas branch exit, is provided with the pipeline that is connected with the compressor air suction mouth in the bottom of cylindrical shell.
The beneficial effects of the utility model: when the gas-liquid separator oil return is undesired, only need to change the pipeline that connects cylindrical shell bottom and compressor air suction mouth and get final product, and do not waste compressor oil, shorten new product development cycle, utilize the gas-liquid separator internal volume to greatest extent, the economical with materials cost.
Design principle of the present utility model is: in the compressor operating process, refrigerant enters into gas-liquid separator inside by gas subentry pipe, carries out gas-liquid separation, oil separation then.Because the fluid liquid flow velocity of gas-liquid separator cylindrical shell bottom is much smaller than compressor air suction mouth place gas flow rate, therefore can be according to Bernoulli equation in the moving fluid mechanics, select suitable pipeline connection cylindrical shell bottom and compressor air suction mouth, effectively control gas-liquid separator bottom oil level guarantees not accumulate excessive compressor oil bottom the air-conditioner gas-liquid separator cylindrical shell in service.
Description of drawings
Fig. 1 is the structural representation of prior art gas-liquid separator;
Fig. 2 is the structural representation of the utility model gas-liquid separator.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated: as shown in Figure 2, a kind of novel gas-liquid separator, comprise cylindrical shell 1, the top of cylindrical shell 1 is provided with gas subentry pipe 2, be provided with U type pipe 3 in the cylindrical shell 1, one end of U type pipe 3 passes from the top of cylindrical shell and forms gas and divide outlet 4, divides in cylindrical shell 1 inside, near gas on the U type pipe at outlet place to offer balancing orifice 5, is provided with the pipeline 6 that is connected with compressor air suction mouth (not shown) in the bottom of cylindrical shell 1.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
