Abstract
The invention discloses a kind of valve for refrigerating compressor group structures, including suction valve chip and valve plate, suction valve chip is equipped with air-breathing tongue and supporting zone, side is fitted equipped with clearance filling muscle, in gap when suction valve chip is closed between clearance filling muscle insertion air-breathing tongue and supporting zone with suction valve chip on valve plate.The shape of clearance filling muscle can and air-breathing tongue match with the gap between supporting zone, the height of clearance filling muscle may be less than or equal to the thickness of suction valve chip.The present invention can both reduce the clearance volume of valve group, promote compressor volumetric efficiency, and advantageously reduce the material cost of monoblock type suction valve chip, reduce the difficulty of processing of suction valve chip.
Description
Technical field
The present invention relates to technical field of refrigeration compressors, specifically a kind of to be applied to small-sized reciprocating-piston type refrigerating pressure
The valve group of contracting machine.
Background technology
Reciprocating piston refrigeration compressor by the operating of motor, drives toggle to push piston at work
It moves back and forth, the suction and discharge valve block in valve group is intermittently opened under piston effect, closed, constantly sucking and discharge refrigeration
Agent, to realize refrigeration.In the various factors for influencing compressor efficiency, volumetric efficiency is very important one.And certainly
In the factor for determining compressor volumetric efficiency, clearance volume, i.e. piston reach after top dead center, are formed between pistons end and valve plate
Residual volume be very important.Clearance volume is smaller, and gas volume of the residual gas in air-breathing shared by reflation is got over
Small, volumetric efficiency is higher.In the compressor using monoblock type absorption valve plate structure, tongue part and the support of suction valve chip
Interregional gap is the part for constituting clearance volume.In order to reduce the clearance volume of the part as much as possible, often should
Gap is sized to very little, however this design can cause the material cost of suction valve chip and difficulty of processing to increase.Such as figure
1, shown in Fig. 2 and Fig. 3, existing air-breathing valve group includes suction valve chip 6 and valve plate 5, and suction valve chip 6 includes supporting zone 1, gap 2
With air-breathing tongue 3.For the considerations of reducing clearance volume as far as possible, the width general control in gap 2 0.4mm to 0.6mm it
Between, the valve plate material not being used only is more, and narrow gap causes suction valve chip difficulty of processing larger.
Invention content
Technical problem to be solved by the present invention lies in a kind of clearance volume that can both reduce valve group is proposed, compression is promoted
Machine volumetric efficiency, and advantageously reduce the material cost of monoblock type suction valve chip and the valve for refrigerating compressor group knot of difficulty of processing
Structure.
In order to solve the above technical problems, a kind of valve for refrigerating compressor group structure of the present invention includes suction valve chip and valve plate,
The suction valve chip is equipped with air-breathing tongue and supporting zone, and the side that fits with the suction valve chip on the valve plate is equipped with remaining
Gap fills muscle, the suction valve chip when closing the clearance filling muscle be embedded in the seam between the air-breathing tongue and the supporting zone
In gap.
A kind of above-mentioned valve for refrigerating compressor group structure, the shape of clearance filling muscle and the air-breathing tongue with it is described
Gap between supporting zone matches.
The height of a kind of above-mentioned valve for refrigerating compressor group structure, the clearance filling muscle is less than or equal to the inlet valve
The thickness of piece.
A kind of above-mentioned valve for refrigerating compressor group structure, the valve plate are made of nonmetallic materials.
The present invention is as a result of above-mentioned technical pattern, when suction valve chip is closed, the clearance filling muscle insertion on valve plate
It in gap on to suction valve chip between air-breathing tongue and supporting zone, can not only reduce the clearance volume of valve group, promote pressure
The volumetric efficiency of contracting machine；And the gap of air-breathing tongue and supporting zone can be made to use larger size in design, be conducive to save
The about material cost and difficulty of processing of valve block rapidoprint, reduction suction valve chip.Meanwhile valve plate is made of nonmetallic materials,
It can help to valve group noise reduction.
Description of the drawings
Fig. 1 is the structural schematic diagram of existing monoblock type tongue type suction valve chip；
Fig. 2 is the structural schematic diagram of existing valve plate；
Fig. 3 is assembling structure schematic diagram when existing monoblock type tongue type suction valve chip is closed；
Fig. 4 is the structural schematic diagram of suction valve chip in valve group of the present invention；
Fig. 5 is the structural schematic diagram of valve plate in valve group of the present invention；
Fig. 6 is assembling structure schematic diagram when valve group suction valve chip of the present invention is closed.
Specific implementation mode
As shown in fig. 6, valve for refrigerating compressor group structure of the present invention includes suction valve chip 6 and valve plate 5.
As shown in figure 4, suction valve chip 6 is monolithic construction, the wherein gap 2 between air-breathing tongue 3 and supporting zone 1 is done
Widening treatment.In this manner it is possible to save the rapidoprint of suction valve chip 1, but also difficulty of processing can be reduced.
As shown in figure 5, the side that fits with suction valve chip 6 on valve plate 5 is provided with clearance filling muscle 4, which fills muscle 4
Shape and the air-breathing tongue 3 and supporting zone 1 of suction valve chip 6 between gap 2 shape coincide, clearance fill muscle 4 height
Less than or equal to the thickness of matched suction valve chip 6.
As shown in fig. 6, when suction valve chip 6 is closed, the clearance filling muscle 4 on valve plate 5 is embedded in air-breathing tongue 3 and Support
In gap 2 between domain 1, to play the role of reducing clearance volume.
In structure of the invention, valve plate 5 may be used nonmetallic materials and be molded, and be conducive to valve group noise reduction.
