Description
Technical field
The utility model is related to compressor field, and in particular to a kind of coolant injection structure and compressor.
Background technology
Gas-supplying enthalpy-increasing technology refers to the gas that a part of intermediate pressure is sucked by intermediate pressure suction hole, and by part
The refrigerant mixing recompression of compression, adds the refrigerant flow in condenser, the enthalpy difference of refrigeration major loop is increased, so as to carry
High compressor efficiency.
Mainly apply in gas coolant injection (Economizer Vapor Injection, EVI) structure of existing patent
Scroll compressor, or carry spring, inserted block and valve element in rotary compressor.
As shown in Figure 1 and Figure 2, when injection refrigerant is opened, gas impacts valve element 21 and spring 3 is made after the entrance of inserted block 1
Into extruding, air-flow enters spray-hole 51,52 from the gas channel 4 on both sides, and then enters upper and lower air cylinders progress tonifying Qi.Injection is closed
When, the internal pressure of valve element 21 is higher than external pressure, and spring 3 is in original position.
No matter sprayed in the injection structure and be turned on and off there is a situation where in jet 51,52 gas blowby above and below gas,
The extruding of paired springs 3 can be made, causes spring 3 to occur arching upward or other exceptions.In this case, spring 3 very likely breaks
Split or be damaged, and then the serious problems such as complete machine stall or defective insulation or even electric leakage are caused into compressor.
The content of the invention
In view of problems of the prior art, the purpose of this utility model is to provide a kind of coolant injection structure, pass through
Improve valve core structure, cancel the spring of injection structure in the prior art, Gas-supplying enthalpy-increasing can either be realized, spring can be avoided to break again
Split or the impaired complete machine stall caused or the serious problems such as defective insulation or even electric leakage, improve reliability.
The utility model provides a kind of coolant injection structure, and coolant injection structure includes body and is arranged at body interior
Inserted block and valve element, be provided with overdraught passage and downstream passage between valve element on the inside of body, valve element is cylinder, cylinder
Body is provided with projection away from the side of inserted block, and the area on raised top is less than the cross-sectional area of cylinder.
Further, overdraught passage is provided with the jet connected with upper cylinder.
Further, downstream passage is provided with the jet connected with lower cylinder.
Further, raised is column structure or cone structure.
Further, raised top deviates from the side of inserted block with cylinder, is connected by cylindroid, arc surface or taper surface
Connect.
The utility model also provides a kind of compressor, including above-mentioned coolant injection structure.
Compared with prior art, the utility model is provided coolant injection structure, compressor and system, with following beneficial
Effect：When injection is opened, gas enters impact valve element from inserted block, and air-flow enters spray-hole, Jin Erjin from the gas channel on both sides
Enter upper and lower air cylinders and carry out tonifying Qi；When injection is closed, valve core inside pressure is higher than external pressure, and then original position is gone back on valve element top.Should
Injection structure cancels the spring of injection structure in the prior art, can not only avoid spring breakage or the impaired complete machine stall caused
Or the defective insulation even serious problems such as electric leakage；Gas-supplying enthalpy-increasing can be realized simultaneously, delivery temperature is effectively reduced at high temperature, is kept away
Exempt from insulating materials deterioration；Heating capacity can be effectively improved under worst cold case again, it is ensured that cryogenic property.

As shown in Fig. 3, Fig. 4, Fig. 5, the coolant injection structure of one embodiment of the present utility model, including body 6 and
Inserted block 1 and valve element 22 inside body 6 are arranged at, overdraught passage 41 and lower gas are provided between the inner side of body 6 and valve element 22
Circulation road 42, valve element 22 is cylinder, and cylinder is provided with projection 221, the face on the top of projection 221 away from the side of inserted block 1
Cross-sectional area of the product less than cylinder.
Overdraught passage 41 is provided with the jet 51 connected with upper cylinder.
Downstream passage 42 is provided with the jet 52 connected with lower cylinder.
When injection is opened, gas impacts valve element 22 after the entrance of inserted block 1, and air-flow is from overdraught passage 41 and downstream passage
42 enter spray-hole 51,52, and then enter upper and lower air cylinders progress tonifying Qi；When injection is closed, the internal pressure of valve element 22 is higher than outside
Pressure, and then valve element 22 is pushed up go back to original position.
Coolant injection structure in the present embodiment, is improved by valve core structure, cancels the bullet of injection structure in the prior art
Spring, building block is relatively fewer, can either realize Gas-supplying enthalpy-increasing, and spring breakage or the impaired complete machine stall caused can be avoided again
