Abstract
The utility model discloses a pressure-regulating temperature-regulating liquid pouring device for refrigerants, which is composed of a compressor, an electromagnetic valve, a two-way valve, a pressure reducing valve, a pressure protector, etc. The utility model has simple structure, low cost, portability and lightness, and convenient operation. Through the work of the components such as the compressor, etc., the gas in a small bottle is pressed into a large bottle, then the pressure and the temperature of the small bottle both are reduced, the pressure and the temperature of the large bottle both are increased, and certain pressure difference is generated between the large and the small bottles. Under down time, the relevant valves are automatically opened or closed, the high-pressure liquid in the large bottle (the large bottle is inverted) automatically gets into the small bottle, the liquid pouring process is completed, and liquid pouring tasks can be completed once or many times. Thus, in the process of separating and loading the refrigerants, time and labor are both saved, the residual gas in a pipeline can be taken back, and unnecessary waste and environmental pollution caused by the waste can be reduced.
Description
(refrigerant refers to F to the utility model discloses a kind of refrigerant
12, F
22, F
502, R
134a) pressure regulation temperature adjustment liquid pouring machine.
At present refrigerant falls trouble of liquor ratio, pours bottle in order to make big bottle refrigerant, and big bottle hot water commonly used waters, fire is roasting even blow heating with gas welding, makes the supercharging of big bottle refrigerant; And in order to make bottle decompression, then with cold water dash, freezing, venting etc., form big bottle pressure reduction like this, realize the purpose of falling liquid.Do so promptly time-consuming, bothersome, cause unnecessary waste and environmental pollution again.
Task of the present utility model provide a kind of volume little, in light weight (total weight is no more than 15kg), cheap, do not need fixed venue, can at will move, time saving and energy saving and can regain pipeline residual air, can the pressure regulation temperature adjustment and have a refrigerant liquid pouring machine of pressure protect.To reach more convenient, safer packing refrigerant, reduce unnecessary waste and pollution on the environment.
The utility model is achieved in that and is connected with the electromagnetic valve inlet pipe connection on the compressor high-pressure pipe; valve connection pipe and check valve inlet pipe connection on the two-way valve; a give vent to anger end of connection pipe of check valve is connected with filter; pressure protector is connected check valve and gives vent to anger on the connection pipe; the public connection pipe of two-way valve and the check valve connection pipe of giving vent to anger is connected; the other end of filter is connected with connection pipe with cylinder joint; electromagnetic valve connection pipe and the reducing valve connection pipe of giving vent to anger of giving vent to anger is connected on the compressor reducer machine low-voltage tube; the reducing valve inlet pipe connection is connected with cylinder joint, and the reducing valve inlet pipe connection is connected with two-way valve lower valve connection pipe.3 gears of the source switch branch that is complementary " 0,1,2, ", the cw start, " 0 " is the position of shutdown, and the moment energising of " 1 " shelves electromagnetic valve makes electromagnetic valve open-minded, and the high pressure gas pressure release is easily started for compressor and prepares; " 2 " shelves compressor normal operation (" 1 " shelves closed electromagnetic valve) makes bottle gas be pressed into big bottle, the cooling of bottle step-down at this moment, and the supercharging of big bottle heats, and produces certain pressure reduction between big bottle; Forward " 0 " shelves to by " 2 " shelves conter clockwise during shutdown; through the moment energising of " 1 " shelves electromagnetic valve; electromagnetic valve is open-minded; compressor pressure piping gas flows into compressor low pressure; make closed check valve; valve SELF CL on the two-way valve; lower valve is opened automatically; the reducing valve SELF CL; make big bottle liquid (big bottle is put upside down) by cylinder joint, the public connection pipe of filter, filter connection pipe, two-way valve, two-way valve, two-way valve lower valve connection pipe and reducing valve inlet pipe connection, cylinder joint injects bottle; the process of falling liquid of finishing, the once task of falling liquid of repeatedly finishing.
Because refrigerant pressure regulation temperature adjustment liquid pouring machine is made up of common compressor, electromagnetic valve, two-way valve, check valve, reducing valve, pressure protector etc.; simple in structure, cheap; can be convenient, safely, save time, labour-saving packing refrigerant, and can also regain pipeline residual air.
Below in conjunction with accompanying drawing the utility model is described in further detail.
