Description
Technical field
The utility model relates to a kind of air conditioner parts, relates in particular to a kind of modulating valve of idle call.
Background technique
Modulating valve generally also is expansion valve or is called throttle valve, will be used for removing the pressure of liquid refrigerant exactly, refrigeration agent can be expanded in vaporizer become steam.Usually be arranged between the condenser and vaporizer of air-conditioning system.Existing modulating valve generally is to comprise diaphragm, needle, temp-sensitive apparatus, spring, and needle is fixed in the diaphragm bottom, and effect has temp-sensitive apparatus pressure, evaporator vapor tension and spring tension on the diaphragm, and the working state of needle three power is thus come balance.When compressor shuts down, needle was closed when external and internal pressure equated, when compressor operating, the vapor tension of the inlet of the pressure height in the outlet port of condenser and vaporizer is little, so needle is raised valve open, liquid refrigeration agent enters vaporizer, along with the variation of evaporator outlet place temperature and evaporator place vapor tension, the aperture of needle also changes thereupon, thereby has regulated the flow of liquid refrigerant.Can adjust the tension force of spring by screw, and then realize the refrigerant flow adjustment.But this modulating valve is realized the adjustment of refrigerant flow because mainly be to regulate by needle by the pressure of temperature sense.When the working pressure of compressor fails to reach normal operating pressure, compressor operating efficient is reduced, the compressor that also weares and teares easily simultaneously is not easy care and maintenance, wastes energy simultaneously.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of idle call modulating valve that can adapt to the operating range of broad and can improve compressor efficiency is provided, can also make simultaneously compressor displacement easy care and maintenance, operation is also convenient, cost is low.
Technological scheme
For achieving the above object, the utility model has adopted following technical proposals:
This idle call modulating valve, an end is provided with inlet pipeline on the valve body, the other end is provided with outlet conduit, be provided with pressure piston, needle, temp-sensitive apparatus and spring in the valve body, needle is fixed on the pressure piston, and effect has temp-sensitive apparatus pressure, inlet's condensing air pressure and spring tension on the pressure piston.
Described pressure piston is arranged in the modulating valve main body base, and pressure piston is provided with the valve frame, and needle is arranged on the valve frame, and spring housing is located on the pressure piston.
Also be provided with the interlock pin under the pressure piston in the described modulating valve main body base, be provided with gas spring in the gas spring seat of interlock pin lower end, between gas spring and interlock pin, be provided with jump ring.
Also be provided with the manual modulation valve arm more than the described modulating valve main body base pressure piston, a manual modulation valve arm and a pad join, and both are arranged in the manual tune valve seat for it, and manual tune valve seat upper end and sealing cover join.
Described gas spring seat lower end links to each other with temp-sensitive apparatus, and this temp-sensitive apparatus comprises temperature-sensitive pipe and bulb.
Beneficial effect
By technique scheme, thereby this model utility has following beneficial effect:
1. the operating range that can adapt to broad, no matter the power of air-conditioning is much, can both reach the refrigeration of proper functioning;
2. can improve the working efficiency of compressor;
3. easy care and maintenance;
4. easy to operate, processing cost is low.
Description of drawings
Fig. 1 is the solid assembling schematic representation of this model utility.
Fig. 2 is the whole schematic perspective view of this model utility.
Embodiment
Below in conjunction with accompanying drawing the utility model is made further description.
As shown in Figure 1 and Figure 2, an end is provided with inlet pipeline 1 on this model utility idle call modulating valve valve body, the other end is provided with outlet conduit 2, be provided with pressure piston 3, needle 4, temp-sensitive apparatus 5 and spring 6 in the valve body, needle is fixed on the pressure piston, and effect has temp-sensitive apparatus pressure, inlet's condensing air pressure and spring tension on the pressure piston; Described pressure piston is arranged in the modulating valve main body base 7, and pressure piston is provided with valve frame 72, and needle is arranged on the valve frame, and spring housing is located on the pressure piston; In described modulating valve main body base, also be provided with interlock pin 8 under the pressure piston, be provided with gas spring 92 in the gas spring seat 9 of interlock pin lower end, between gas spring and interlock pin, be provided with jump ring 94.Also be provided with manual modulation valve arm 10 more than the described modulating valve main body base pressure piston, a manual modulation valve arm and a pad 11 join, and both are arranged in the manual tune valve seat 12 its, and manual tune valve seat upper end and sealing cover 13 join; Described gas spring seat lower end links to each other with temp-sensitive apparatus, and this temp-sensitive apparatus 5 comprises temperature-sensitive connecting tube 52 and bulb 54.Described interlock pin is average three of being provided with, and jump ring blocks gas spring and makes it to be positioned at all the time the gas spring seat.
When operation of air conditioner, act on the power on the pressure piston, mainly contain thrust and the power of gas spring and the opposing force of spring of condensing air pressure to piston.When between air-conditioning and heat pump, changing, temp-sensitive apparatus transmits the pressure of a vertical direction and gives gas spring, pass to the interlock pin by gas spring, pass to pressure piston and changed original balance by the interlock pin again, and this moment, the valve pin on the pressure piston changed, to reach secondary balance.Effect downforce piston in above-mentioned three power is in state of equilibrium, has fixing refrigerant flow to flow through in the modulating valve.Can certainly be by the tension force of manual tune arm Regulation spring, to reach best refrigeration to piston.When not having pressure difference between two pipelines of turnover, pressure piston is subjected to the tension force of a vertical direction of spring, though being arranged this moment, pressure spring gives a rightabout pressure simultaneously, but the pressure of pressure spring is much smaller than the tension force of a vertical direction of spring, so needle closes valve.Compared with prior art, because it mainly is to the thrust of the piston tension force of spring that contends with, so be not subjected to any power influences by condensing air pressure.The operating range that therefore can adapt to broad, no matter the power of air-conditioning is much, can both reach the refrigeration of proper functioning; Because compressor operation is just opened valve during to normal refrigeration work pressure, therefore can improve the working efficiency of compressor; And it to be that single main frame is that condensing agent directly carries again cold, add condenser and dispel the heat when bad, the high pressure of compressor can not show too high and power down, but high low pressure slowly promotes simultaneously, room temperature also changes gradually, therefore can provide information to the user in advance, so easy care and maintenance; This valve is automatic adjusting simultaneously, so easy to operate, processing cost is low.
