Description
Technical field
The utility model relates to linear compressor technical fields, more particularly to a kind of linear compressor suction and discharge valve group
Part and linear compressor.
Background technique
Linear compressor is refrigerant gas to be drawn into cylinder, and make piston in vapour using the driving force of linear electric machine
It is done reciprocating linear motion in cylinder to compress refrigerant gas, the refrigerant of compressive state is then discharged to condenser, is finally steaming
It sends out device and realizes refrigeration effect.Air intake passage will be arranged in the piston of linear compressor, and suction valve chip need to be mounted on the end face of piston.
The end face that suction valve chip is fixed on piston by screw is generallyd use at present, specific there are two types of schemes.
A kind of scheme is that suction valve chip is fixed by screws on piston, and screw protrudes from suction valve chip, nonmetallic exhaust
Valve block is fixed in cylinder head assemblies, and nonmetallic exhaust valve plate position corresponding with screw opens up screw relief hole.This scheme is deposited
In following drawback: (1) suction valve chip is connected using screw, and screw fastening needs torque, and inevitable Floor screw will have head of screw,
Exhaust valve plate position corresponding with screw needs to make head of screw relief hole, this relief hole more slightly larger than head of screw can just can guarantee
Head of screw is fallen completely within wherein, causes to interfere to prevent the bias during installation concentricity and valve block opening and closing.But relief hole
In the presence of clearance volume is increased, refrigerating capacity is caused to decline.(2) suction valve chip is connected using screw, to prevent gas from threaded hole
Place's leakage, need to be such that suction valve chip is bonded completely with piston end surface to guarantee mounting plane degree, and therefore, screw and suction valve chip are matched
Conjunction face need to guarantee high-precision, this will increase the complete machine cost of compressor.(3) presence of exhaust valve plate relief hole reduces non-gold
The mechanical strength for belonging to exhaust valve plate, limits the design of exhaust valve plate loss of weight, further limits compressor to higher frequency
The development in direction.
Another scheme is that suction valve chip is fixed by screws on piston, and screw protrudes from suction valve chip, stainless steel row
Air valve plate is fixed on valve plate, and valve plate position corresponding with screw opens up screw relief hole.There is also following drawbacks for this scheme:
(1) suction valve chip is connected using screw, and screw fastening needs torque, and inevitable Floor screw will have head of screw, valve plate and screw
Corresponding position needs to make head of screw relief hole, this relief hole more slightly larger than head of screw can just can guarantee that head of screw is fallen completely within
Wherein, cause to interfere to prevent the bias during installation concentricity and valve block opening and closing.The presence of relief hole inevitably increases
Clearance volume, causes refrigerating capacity to decline, is unfavorable for the performance of maximum cooling capacity.In addition, exhaust valve plate is to rigidly fix with valve plate
, do not allow piston slap valve plate, displacement sensor need to be used to piston stroke strict control, increase cost, also reduce
Reliability.(2) suction valve chip is connected using screw, to prevent gas from leaking from threaded hole, need to make suction valve chip and piston end
Face is bonded completely to guarantee mounting plane degree, and therefore, the mating surface of screw and suction valve chip need to guarantee high-precision, this will increase pressure
The complete machine cost of contracting machine.(3) presence of exhaust valve plate relief hole reduces the mechanical strength of exhaust valve plate, limits exhaust valve
The design of piece loss of weight further limits development of the compressor to higher frequency direction.
