Abstract
The invention discloses a kind of valve for refrigerating compressor group structure, including suction valve chip and valve plate, suction valve chip is provided with air-breathing tongue and supporting zone, the side that fits with suction valve chip on valve plate is provided with clearance filling muscle, when suction valve chip is closed in the embedded gap between air-breathing tongue and supporting zone of clearance filling muscle.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, lift compressor volumetric efficiency, advantageously reduce the material cost of monoblock type suction valve chip again, reduce the difficulty of processing of suction valve chip.
Description
Technical field
The present invention relates to technical field of refrigeration compressors, specifically one kind are applied to small-sized reciprocating-piston type refrigerating pressure
The valve group of contracting machine.
Background technology
Reciprocating piston refrigeration compressor drives toggle to promote piston at work by the operating of motor
Move back and forth, the suction and discharge valve block in valve group is intermittently opened under piston effect, closed, constantly suction and discharge refrigeration
Agent, so as to realize refrigeration.In the various factors for affecting compressor efficiency, volumetric efficiency is very important one.And certainly
Determine in the factor of compressor volumetric efficiency, clearance volume, i.e. piston reach after top dead center, formed between pistons end and valve plate
Residual volume be very important.Clearance volume is less, and gas volume of the residual gas in air-breathing shared by reflation is got over
Little, 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, but this design can cause the material cost and difficulty of processing increase of suction valve chip.As schemed
1st, 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 consideration for 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 for not only using is more, and narrow gap causes suction valve chip difficulty of processing larger.
The content of the invention
The technical problem to be solved is to propose a kind of clearance volume that can both reduce valve group, lifts compression
Machine volumetric efficiency, advantageously reduces the valve for refrigerating compressor group knot of the material cost and difficulty of processing of monoblock type suction valve chip again
Structure.
To solve above-mentioned technical problem, a kind of valve for refrigerating compressor group structure of the invention includes suction valve chip and valve plate,
The suction valve chip is provided with air-breathing tongue and supporting zone, and the side that fits with the suction valve chip on the valve plate is provided with remaining
Gap fills muscle, and during the suction valve chip closing, the clearance filling muscle is 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 and the air-breathing tongue of clearance filling muscle with it is described
Gap between supporting zone matches.
A kind of above-mentioned valve for refrigerating compressor group structure, the height of the clearance filling muscle are 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 using nonmetallic materials.
As a result of above-mentioned technical pattern, when suction valve chip is closed, the clearance filling muscle on valve plate is embedded in the present invention
The clearance volume of valve group in gap on suction valve chip between air-breathing tongue and supporting zone, not only can be reduced, pressure is lifted
The volumetric efficiency of contracting machine；And air-breathing tongue and the gap of supporting zone can be made to adopt more large scale in design, be conducive to section
About valve block rapidoprint, reduce suction valve chip material cost and difficulty of processing.Meanwhile, valve plate is made using nonmetallic materials,
Can help to valve group noise reduction.

Specific embodiment
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, muscle 4 is filled in the clearance
Shape and suction valve chip 6 air-breathing tongue 3 and supporting zone 1 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, so as to play a part of to reduce clearance volume.
In present configuration, valve plate 5 can be molded using nonmetallic materials, be conducive to valve group noise reduction.
