Background technique
Last 100 years has been carried out in the research of adsorptive refrigeration, but does not walk out laboratory applications in reality always, and subject matter is that heating time is long, and volume is big, and temperature fluctuation is big, and COP is low, and refrigerating speed is slow.Chinese patent application " fishing boat cooling machine set " with patent publication No. 1636826 is an example, it discloses a kind of fishing boat cooling machine set, is made up of reversing arrangement, generator, safety check, condenser, cistern, throttle valve, vaporizer, blower fan, freezer, waste pipe, solenoid valve, electronic plate valve, thermometer, pressure gauge, non freezing solution recycle pump; Owing to be to adopt absorption principle, utilize fishing boat engine tail gas waste-heat refrigeration, ice making, turn waste into wealth, guaranteed the purification of ocean, do not need electric energy to drive, compressor-free has been avoided the pollution to the ocean, has saved the energy, has improved refrigerating capacity; Reduced fishing boat band ice operation load, guaranteed the quality of off-lying sea fishing, increased the product reserves, enlarged the developing ability of fishing boat, realized the reasonable disposition of China's fishing boat off-lying sea fishing cooling machine set to the off-lying sea.But, the cistern of this cooling machine set is communicated with vaporizer by a manual throttle valve, because manual throttle valve can not overcome the size that throttling passage is in time adjusted in the variation of unbalanced adsorption force and desorption pressure and ice making or the required situation of air-conditioning, to such an extent as in fact absortion type refrigerating equipment can not work effectively, even can't normally use at all.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of suction expansion valve that is applicable to absortion type refrigerating equipment is provided, it can make big or small unit in time adjust the size of throttling passage according to the variation of unbalanced adsorption force and desorption pressure and ice making or the required situation of air-conditioning, makes absortion type refrigerating equipment can carry out work effectively.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
A kind of suction expansion valve, comprise stainless steel body and the valve chamber that constitutes by valve body, the inflow path and the refrigeration agent outflow pathway that is connected to vaporizer that flow into refrigeration agent from the refrigeration agent reservoir vessel are arranged on valve body, between inflow path and outflow pathway, be provided with throttle orifice and valve, it is characterized in that: in described valve chamber, have stainless steel ripple elastomer that valve chamber is divided into A chamber and B chamber, the valve indoor at B connects stainless steel ripple elastomer by drive link, on the indoor stainless steel ripple of A elastomer, a pressure spring is set, the upper end of pressure spring connects the adjustment plate of adjusting on the screw rod, adjusts screw rod and fixes by adjusting locking nut.
For optimizing technique scheme, the measure that the utility model is taked also comprises:
Adjust the locking nut outside on the described valve body and be provided with the stainless steel protection lid;
Described stainless steel ripple elastomer is the dome shape;
Between the bottom of described valve and the valve chamber inwall spring is arranged.
Because the utility model has been taked above-mentioned technical measures, it compared with prior art has following advantage:
1, the situation of variation in pressure is adjusted the size of throttling passage automatically after its coolant condensation that can cause according to the variation of unbalanced adsorption force in the unit time and desorption pressure, natural temperature differential and unit self work, can keep the wave range of evaporating pressure to be stabilized in 0.2 kg/cm, make absortion type refrigerating equipment can carry out work effectively;
2, use stainless steel material to make, have well corrosion-resistant, heat resistance;
3, big or small unit is general, and ice making and air-conditioning all can use.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
With reference to accompanying drawing, the utility model comprises stainless steel body 3 and the valve chamber that is made of valve body 3, and the inflow path 11 and the refrigeration agent outflow pathway 9 that is connected to vaporizer that flow into refrigeration agent from the refrigeration agent reservoir vessel are arranged on valve body 3.Between inflow path 11 and outflow pathway 9, be provided with throttle orifice 12.The general refrigeration agent that adopts is a liquefied ammonia on the absorption refrigeration unit, is to flow through next liquefied ammonia from liquid ammonia storage tank through what flow into path 11, and 12 back vaporizations flow to vaporizer from outflow pathway 9 to liquefied ammonia through throttle orifice.Valve 8 is arranged, the size of valve 8 may command throttle orifices 12 on the throttle orifice 12.Between the bottom of valve 8 and valve chamber inwall, a spring 10 is arranged.In valve chamber, there is stainless steel ripple elastomer 6 that valve chamber is divided into A chamber 5 and B chamber 13.Stainless steel ripple elastomer 6 can be made into the dome shape that adapts with valve body 3 inner valve chamber.Valve 8 in B chamber 13 connects stainless steel ripple elastomer 6 by drive link 7, and a pressure spring 4 is set on the stainless steel ripple elastomer 6 in A chamber 5.The upper end of pressure spring 4 connects the adjustment plate of adjusting on the screw rod 14 15, and it is fixing by adjusting locking nut 16 to adjust screw rod 14.Adjust locking nut 16 outsides on the valve body 3 and be provided with stainless steel protection lid 1 and seal ring 2, in case stainless steel ripple elastomer 6 causes the leakage of refrigeration agent after damaging naturally.The utility model whole component except that Sealing all use stainless steel material to make.
The situation that the evaporating pressure that causes along with unbalanced adsorptive pressure in the unit time and desorption pressure changes, affact on the stainless steel ripple elastomer 6 by cooling machine set pipeline and the utility model outflow pathway 9, stainless steel ripple elastomer 6 is delivered to valve 8 according to the setting value of adjusting screw rod 14 by drive link 7, valve 8 is the size of can regulate throttle orifice 12, with the throughput of control liquefied ammonia.Because natural temperature differential and unit self operating temperature reach desorption off and on, pressure differs greatly after being enough to cause the coolant condensation, inflow path 11 of the present utility model and valve 8 are done the adjustment of outflow size according to the needs of adsorption force size, and dexterously the coolant of surplus is stopped and be stored in and flow into 11 sections in path, make absortion type refrigerating equipment can carry out work effectively.According to the size of absortion type refrigerating equipment power and the needs of ice making or air-conditioning, can regulate and adjust screw rod 14, be applied to elastic force on the stainless steel ripple elastomer 6 to regulate pressure spring 4, adjust screw rod 14 can access coupling 2000～90000 kilocalories/hour unit, and ice making and air-conditioning all can use.Fix adjustment screw rod 14 with adjusting locking nut 16 after adjustment is finished, can overcome the influence of mechanical vibration, and avoid adjusting screw rod 14 bounce-backs.Build protective cover 1 at last.
The utility model is mainly used in absortion type refrigerating equipment and absorption refrigeration equipment, can be used for also that needs are corrosion-resistant, the voltage stabilizing in other pipelines of heatproof, the usefulness of decompression.
