Abstract
The utility model relates to a heat stop valve, comprising a temperature inducing bag (2). The utility model is characterized in that the temperature inducing bag (2) is connected with a bellows (4) by a capillary tube (3), the bellows (4) is installed in a shell body, the lower part of the bellows (4) is connected with a pushing rod (6), the pushing rod (6) is wound with a spring (5), one end of a spring piece (9) is fixed under a valve seat (13), a liquid entering tube (11) is installed under the shell body, and the side surface of the shell body is provided with a liquid outlet tube (12). The utility model has the advantages of simple structure, low cost, no noise, no need of repair and long service life, when the utility model is used, the utility model can be welded, and the utility model can save 30-40% of electricity for refrigerators, refrigeration tanks and show boxes.
Description
The utility model relates to a kind of parts of refrigeration plant, particularly relates to the heating power stop valve of a kind of refrigerator, refrigerator elimination crossfire.
The major vendor of more external in recent years production refrigerators increases significantly to the interest that adopts the capillary-compensated device, because it can reduce cost by simplified structure, improves sealing, improves the reliability of refrigerator.The refrigerator of one-period sex work; in its compressor shutdown process and since its refrigeration agent by the throttling device to the vaporizer crossfire, make pressure, the temperature rising of vaporizer; and after the refrigerating capacity loss that causes adding, this being lost in reaches 9-10% in the household refrigerator.Experiment to the small-business cold storage cabinet shows, adopts solenoid valve periodically to work, eliminate crossfire and can make the operating ratio of compressor reduce by 44.7%, and its power consumption reduction by 43.2%, the delivery temperature of compressor on average reduces by 5～7 ℃ simultaneously.At present, in family expenses refrigerator, refrigerator, small-sized showcase, do not adopt the device of eliminating crossfire both at home and abroad as yet, adopt solenoid valve to cut off crossfire in some big-and-middle-sized showcase, the keying of solenoid valve and the keying of compressor are synchronous, control refrigeration agent with the keying of solenoid valve and flow to break-make capillaceous by condenser.The Danfoss AS of Denmark produces a kind of heating power expansion valve of special role, and promptly double-action TDE valve is used for the effect of relatively large refrigeration, the existing heating power expansion valve of heat pump, and the effect of heating power stop valve is arranged again.But above-mentioned these devices also have the some shortcomings part, and the life-span of solenoid valve is not long, and power consumption has noise, and easy break-down, cost height, TDE double-purpose valve then are outer balanced type, complex structure, cost height.
The purpose of this utility model provides a kind of heating power stop valve, and it can remedy the above-mentioned deficiency of existing apparatus.
The utility model has a bulb, it is characterized in that bulb is connected with bellows by capillary tube, and the latter is contained in the housing, connect a catch bar under the bellows, catch bar is wound with spring, and an end of spring sheet is fixed on below the valve base, under the housing liquid inlet pipe is housed, drain pipe is equipped with in the side.
The utility model has the advantages that simple in structurely, cost is low, and noise free can weld during use, need not keep in repair, and the life-span is long, can be refrigerator, refrigerator, showcase economize on electricity 30-40%.
Below by embodiment and description of drawings the utility model.
Accompanying drawing is a structural representation of the present utility model.
The utility model has a valve body (8) and a loam cake (7), and they constitute a housing.Liquid inlet pipe (11) is arranged at the bottom of valve body (8), drain pipe (12) is equipped with in the side of loam cake (7), bellows (4) is housed in the housing, catch bar (6) is housed below the latter, one end of spring sheet (9) is fixed on below the valve block (13) by fixing pin (10), catch bar (6) passes valve base (13), and is wound with spring (5), and bellows (4) is connected with bulb (2) by capillary tube (3).
When using the utility model its bulb (2) is affixed on the outlet pipe (1) of the compressor of refrigeration plant, drain pipe (12) is received on the capillary tube of refrigeration plant, liquid inlet pipe (11) is received on the device for drying and filtering.Compressor is opened, after the wall surface temperature of outlet pipe (1) raises, medium in the bulb (2) expands, make bellows (4) elongation and pressure spring (5) downwards by capillary tube (3), catch bar (6) is moved down, and pressuring spring sheet (9) makes opening of valves, refrigeration plant normally moves thereupon, and liquid refrigerant is by the orifice flow mistake on the valve seat in this valve (13).After the compressor shutdown, the medium cooling in the bulb (12) is shunk, and catch bar moves on (6), and valve is then closed.
Claims (1)
1. heating power stop valve, one bulb (2) is arranged, it is characterized in that bulb (2) is connected with bellows (4) by capillary tube (3), the latter is contained in the housing, connect a catch bar (6) under the bellows (4), catch bar (6) is wound with spring (5), and an end of spring sheet (9) is fixed on below the valve base (13), liquid inlet pipe (11) is housed under the housing, and drain pipe (12) is equipped with in the side.
