Carry out the effect of one-level noise reduction, can be to from aerofluxus by the noise reduction lid being provided thereon and be connected with inside it
Valve gap expellant gas carries out the effect of further noise reduction, plays optimization noise reduction and the purpose of vibration damping and effect.
Preferably, described noise reduction lid 22 is internally provided with two noise elimination cavities, the respectively first noise elimination cavity 221
With the second noise elimination cavity 222, it is connected by a gas communication hole 223 between two described noise elimination cavities.Logical
Cross the version in the gas communication hole that two noise elimination cavities are set and connect between the two, it is possible to play gas
Carry out the effect of two-stage series connection noise elimination, play and further it is eliminated the noise and the effect of vibration damping, so that compression
Machine can quiet, stably run.
Preferably, the aperture in described gas communication hole 223 is φ 3～φ 5mm.This is the excellent of gas communication hole
Select the numerical range in aperture, so can effectively accommodate gas and enter the second noise elimination cavity from the first noise elimination cavity,
And also be effective to ensure that gas is gently, stably flow so that gas be unlikely to due to aperture too big and
Increase disturbance and vibration, be also unlikely to owing to aperture is the least and reduce the flowing velocity of gas and cause first to disappear
Pressure in the operatic tunes is excessive and produces potential safety hazard, it is ensured that the safe and reliable operation of compressor complete machine.
Operation principle and the preferred embodiment of the present invention are described below
It is an object of the invention to provide the inside exhaust pipe group of a kind of reciprocating linear compressor, reduce inside exhaust pipe group
