Abstract
The utility model discloses an unloading valve for an air conditioner and comprises a valve body which is connected with an inlet pipe and an outlet pipe, a valve core arranged in the valve body, an adjusting cylinder connected with the valve body which is internally an adjusting spring whose both ends are respectively provided with an adjusting screw plug and a spring vertex plate. The utility model is characterized in that a sealing ring is arranged between the valve core and valve body; the external pliers is arranged on the valve core and is contacted with the end plane of the sealing ring. The valve core is connected with the spring vertex plate via a steel ball. The utility model has the advantages of simple structure, convenient installation, having obvious role of improving overload capacity of the air conditioner under an adverse environment.
Description
Technical field
The utility model relates to the air conditioner accessory, particularly relates to unloading valve used for Air Conditioners.
Background technique
Along with growth in the living standard, the use of air conditioner more and more widely all is widely used in office space, teahouse, hotel and family.Air conditioner under normal circumstances reaches setting temperature meeting autostop, starts automatically again after the temperature departure setting value.But after compressor occurs unusually, can produce high pressure, compressor is jumped machine automatically, and generally can not start in half an hour behind the jumping machine, and the frequent starting of compressor has a strong impact on the working life of compressor simultaneously.Though existing air conditioner pressure is regulated the purpose that unloading valve can reach off-load at present, but existing air conditioner pressure is regulated unloading valve and by diaphragm valve body and adjusting tube is separated into two chambeies, diaphragm adopts the stainless steel impact briquetting, be installed to again on the diaphragm fixed base, need through soldering installation, and spool also needs secondary spring to promote, so the shortcoming that prior art exists has: the one, complex structure, the processing and assembling trouble, cost is big; The 2nd, diaphragm is separated unloading valve and generally only is applicable to the small-power air conditioner.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of simple structure of sealed separation to be provided, and each part processing assembling is laborsaving, the reliability height, and be applicable to the unloading valve used for Air Conditioners of large power air-conditioned device.
The technological scheme of the utility model unloading valve used for Air Conditioners is: a valve body is arranged, valve body connects inlet tube and outer pipe, spool is installed in the valve body, valve body connects regulates tube, regulating in the tube has Regulation spring, and two of Regulation spring has the plug screw of adjusting and spring top flat respectively, it is characterized in that between spool and the valve body seal ring being installed, axle is installed on the spool and with the seal ring Transverse plane with jump ring and contacts, and spool is connected with the spring top flat through steel ball.
Unloading valve used for Air Conditioners of the present utility model is separated into two chambeies to valve body and adjusting tube by seal ring; Axle is installed on the spool with jump ring and makes the seal ring axial restraint; Pressure adjusting spring to spool, closes spool by spring top flat, steel ball, but rotation regulate plug screw make pressure adjusting spring by compression the free adjustment cracking pressure reach the needed cracking pressure value of user.When air-conditioning system pressure did not reach the cracking pressure value of setting, promptly the pressure of pressure adjusting spring acted on the pressure of seal ring greater than fluid, and this moment, spool still sealed up valve port, and off-load is in closed condition; When air-conditioning system pressure reaches the cracking pressure value of setting, the pressure of pressure adjusting spring acts on the pressure of seal ring less than fluid at this moment, make on the seal ring and move, drive on the spool simultaneously and move, the pressure adjusting spring decrement increases, the instantaneous valve port of opening makes fluid flow to low pressure line by valve port through the outer pipe of valve.Behind the opening of valves, system pressure reduces, and valve is in closed condition again, and circulation so repeatedly makes the interior system pressure of air conditioner be no more than a predefined force value all the time and can not continue and raises, thereby makes compressor keep normal operation.This is simple in structure, and is easy for installation, in the overload capacity under the rugged environment significant effect is arranged to improving air conditioner, and is applicable to large power air-conditioned device.
Unloading valve used for Air Conditioners of the present utility model is installed O-ring seals respectively between its described seal ring and the valve body and between seal ring and the spool, further improves sealability.
Description of drawings
Fig. 1 is the structural representation of the utility model unloading valve used for Air Conditioners.
Embodiment
The utility model discloses a kind of unloading valve used for Air Conditioners, as shown in Figure 1, a valve body 2 is arranged, valve body connects inlet tube 3 and outer pipe 1, inlet tube 3 connects pressure duct, outer pipe 1 connects low pressure line, and spool 4 is installed in the valve body, and spool adopts stainless steel integrated formula, fault-free hidden danger, good airproof performance, one of valve body connects adjusting tube 9, and regulating in the tube 9 has Regulation spring 10, two of Regulation spring has the plug screw 11 of adjusting and spring top flat 8 respectively, its major technology is characterised in that installs seal ring 6 between spool 4 and the valve body 2, be shaped on groove on the spool 4, and axle is stuck in the groove of spool 4 with jump ring 7, withstand seal ring 6 Transverse planes, seal ring 6 the other end planes contact with the shaft shoulder of spool 4, thereby make seal ring 6 axial restraints, and spool is connected with spring top flat 8 through steel ball 12.Fluid in the pressure duct arrives valve pocket 14 through inlet tube 3, and act on seal ring 6, when hydrodynamic pressure during greater than the pressure of pressure adjusting spring 10, fluid promotes seal ring 6, and drives spool 4 and move upward, thereby opens the off-load valve port, make high-pressure liquid flow to low pressure line from the off-load valve port, reach the off-load purpose, high-pressure duct system pressure reduces, valve closing.This structure adopts shunting release mode, and the stress-relief process compressor works on, and does not influence the air conditioner refrigerating operation, need not shut down, thereby reduce the frequent starting of compressor, protects compressor effectively, prolongs the working life of compressor.Between its described seal ring 6 and the valve body 2 and between seal ring 6 and the spool 4 O- ring seals 5,13 is installed respectively, is guaranteed not have and leak.
Claims (2)
1, unloading valve used for Air Conditioners, a valve body (2) is arranged, valve body connects inlet tube (3) and outer pipe (1), spool (4) is installed in the valve body, valve body connects regulates tube (9), regulate in the tube Regulation spring (10) is arranged, two of Regulation spring has adjusting plug screw (11) and spring top flat (8) respectively, it is characterized in that between spool (4) and the valve body (2) seal ring (6) being installed, axle is installed in spool (4) with jump ring (7) and upward and with seal ring (6) Transverse plane contacts, and spool is connected with spring top flat (8) through steel ball (12).
