Abstract
The invention discloses two kinds of compressor pollution discharge stoppers, which comprise a fixing part and a bending part, wherein one end of the bending part is fixedly connected with one end of the fixing part, the bending part is a plate-shaped structure with arc shape, the fixing part is a planar plate structure, the other end of the bending part is provided with through-holes, and when the existing compressor exhaust valve plate is hit with the limiting plate, the freezing oil carbon deposition will appear. The carbon deposition is difficult to be discharged outside the cylinder and easy to flow into the compressor cylinder so that the scuffing of cylinder causes a damage to the cylinder. The invention is that the end part of the limiting plate of the exhaust valve is processed into a small circular hole, so that when the freezing oil has carbon deposition, the refrigerant has a certain impact force at the high-pressure and high-speed, and the formed carbon deposition is flushed into the refrigerating system and does not remain in the cylinder of the compressor. The present invention has better reliability than the compressor stopper in the prior art and extends the service life of the compressor.
Description
Technical field
The present invention relates to the Parts of Compressor of refrigeration plant, more particularly, to two kinds blowdowns are spacing with Compressor Air Exhaust Valve Plate
Device.
Background technology
The suction of refrigeration compressor, exhaust valve plate are one of critical components in compressor, and its effect is direct control refrigeration system
The conveying of cold-producing medium in system, the conveying of cold-producing medium is to open and close and carry out by the suction of compressor, exhaust valve plate, particularly exists
In exhaust valve plate opening process due in compressor casing pressure at expulsion higher, and the flow velocity of cold-producing medium is very fast, exhaust valve plate
The oily higher temperature that produces because of shock of freezing producing cold-producing medium when clashing into limiting plate makes freezing oil produce carbon fouling sometimes,
This carbon fouling is harder, is the pollutant in a kind of harmful compressor, if this harder carbon scaling fouling thing can not be arranged
Go out and remain in the cylinder body easily compressor being caused in the cylinder body of compressor by air-breathing in compressor and pulled and make compressor
Damage；On the other hand due to compressor in breathing process if sucking some impurity in refrigeration system is also a kind of to compression
The pollutant that machine is harmful to, remain in compressor cylinder body and also can form, to compressor, the harmful pollutant pulling cylinder body.
If one existing freezer compressor exhaust valve plate creates freezing oil carbon fouling when occurring and clash into limiting plate when
As in the case of carbon fouling be difficult to outside aerofluxuss cylinder body, and easily flow into that to cause compressor to produce scuffing of cylinder bore in the cylinder body of compressor existing
As and cause compressor damage, the present invention is exactly that the end of the limiting plate of air bleeding valve is processed small circular holes when freezing oily hair
Have during carbon fouling due to during aerofluxuss cold-producing medium there is under high-voltage high-speed certain impulsive force, the carbon fouling so being formed is just
Can be flushed in refrigeration system without remaining in the cylinder body of compressor by cold-producing medium.Same compressor also has in breathing process
The harmful impurity in system may be sucked, if tongue tongue refunds system is passed through by high speed and high pressure air-flow in exhaust process
It is unlikely in system to damage compressor.
The refrigeration system of freezer compressor typically all carries out strict cleaning in production process, generally should not have shadow
Ring impurity and the pollutant of refrigeration performance, but mechanical wear can occur in refrigeration system running unavoidably and produce some impurity
With other pollutant, also exhaust valve plate open and close during and valve plate and limiting plate between high speed and high pressure collision and
The high temperature producing makes the harder carbon knot of the freezing oily hair life in compressor, and these impurity, pollutant and carbon fouling are to compressor cylinder
Body is particularly detrimental to cause compressor damage it is easy to pull the cylinder body of compressor, and the row in spacing plate of discharge valve block front end
During pore position processing one tool aperture, if having foreign-matter contamination and carbon fouling in system, it will by the air-flow band of cold-producing medium
In the cylinder body being unlikely to flow to compressor in the system of compressor, so can be avoided the damage of compressor, thus carrying
The high reliability of compressor.

Further, in order to preferably fix Compressor Air Exhaust Valve Plate stop and compressor, another in fixed part
End is provided with perforate, and the axis of perforate is vertical with the axis of fixed part and intersects.
Further, so that uniform force when exhaust valve plate is contacted with exhaust valve plate stop, bending section another
End ovalize, through hole is located in oval plate face, and the axis of bending section passes through the focus of oval plate face.
Further, it is discharged to system in order to realize the pollutant that produce compressor in longtime running and carbon fouling
In cooling system, a diameter of 4-5mm of manhole, the size of through hole can be big according to specific exhaust valve plate and compressor
Little it is adjusted.
Two kinds disclosed by the invention can blowdown refrigeration compressor exhaust valve plate stop, greatly improve compressor can
By property, the service life of the compressor of prolongation.
