Abstract
The invention discloses an air-conditioning compressor exhaust valve piece stopper, which comprises a fixing part and a bending part, in which 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, and the fixing part of the fixing part is connected with the fixed part of the bending part in a stepped shape, and the upper surface of the fixing part is higher than the upper section of the bending part of the joint. The upper surface of the fixing part forms a step with the upper section of the bending part, and the convex block is fixed on the outer arc surface of the other end of the bending part, and the thickness of the bump is equal to the height of the step. In the existing refrigerator compressor discharge valve sheet, the opening degree of the exhaust valve sheet is too large when the exhaust valve sheet is open, and the limit device is generally set, but the noise generated when the existing refrigerator compressor exhaust valve plate collides with the valve plate and the stopper plate when the exhaust valve plate of the refrigerator compressor is opened and closed is large, and the noise generated when the exhaust valve plate and the valve plate and the limit colliding are eliminated by the invention.
Description
Technical field
The present invention relates to a kind of Parts of Compressor of refrigeration plant, more particularly, to a kind of refrigeration compressor ventilating valve block limit
Position 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, and its unlatching
Acted on by alternate load with the tongue of the process valve block closed, as same cantilever swings up and down one in opening process
Sample, can produce noise during making contact between valve block and valve plate and valve block and limiting plate, be produced in refrigeration compressor
Noise essentially from compressor electric motor operation sound, compressor is inhaled, cold-producing medium is under stress inhaling, in exhaust process for exhaust valve plate
Produced airflow noise and produced impact sound when compressor is inhaled, exhaust valve plate and valve plate and valve block are collided with limiting plate,
These sound are all the noises environmentally undesirable to people, for exhaust valve plate and noise produced by limiting plate, hit same
Hit the lower produced noise of power effect different with valve block tongue and limiting plate contact area size, shock contact area is got over
Greatly, the power producing between tongue and limiting plate is also bigger；Existing freezer compressor exhaust valve plate is to prevent exhaust valve plate from opening
When open degree too big, stopping means typically will be set, but the exhaust valve plate stopping means of existing freezer compressor are for example spacing
Plate is not all entirely capable of eliminating produced noise when colliding when exhaust valve plate opens and closes, the present invention with valve plate and limiting plate
Stop in compared to existing technology, domestic refrigerator, air-conditioning etc. have the characteristics that noise is low, greatly meet the need of user
Ask.
Content of the invention
The invention aims to overcoming the deficiencies in the prior art, there is provided the compressor using on a kind of refrigeration plant
Exhaust valve plate stop, to solve existing refrigeration plant during work, the big technical problem of the noise of generation.
The technical solution used in the present invention is as follows:
The invention discloses a kind of refrigeration compressor ventilating valve block stop, including fixed part and bending section, described bending
The one end in portion is fixedly connected with one end of described fixed part, and described bending section is curved platy structure, and described fixed part is
Planar panel structure, the stepped connection in fixed connection place of described fixed part and described bending section and the upper table of described fixed part
Face is higher than the upper edge of bending section described in junction, and the upper surface of described fixed part forms rank with the upper edge of described bending section
Ladder, the extrados of the described bending section other end is fixed with projection, and the thickness of described projection is equal with the height of described ladder.
This design not only makes exhaust valve plate and stop by traditional bump contact when contacting, and is contracted to only one little
The contact of block face, it might even be possible to reach a contact, significantly reduces contact noise.
Further, in order to enable exhaust valve plate with stop uniform force when contacting, will not damage
Bad exhaust valve plate, projection is the solid projection of round pie, and the axis of bending section is through the center of circle of round pie projection.
Further, in order to prior art on exhaust valve plate design match, and stress well-balanced, be easy to pacify
Dress, the other end ovalize of bending section, projection is located at the top of oval plate face, and bending section axis passes through oval plate face
Focus.
Further, in order to Compressor Air Exhaust Valve Plate stop can be fixed assembling with compressor, fixing
The other end in portion is provided with through hole, and the axis of through hole is intersected vertically with the axis of fixed part.
Because the noise that refrigerator produces is mainly produced by compressor, and the noise source of compressor is mainly compressor
Motor rotation when produced and inhaled, produced and inhale during air current flow in exhaust valve plate, exhaust valve plate open and close into
With produced strike note when valve plate and limiting plate collision, and when exhaust valve plate and limiting plate collide produced noise with itself and
The area of collision is relevant, produced noise when the collision bigger exhaust valve plate of area is collided with limiting plate under the effect of same power
Also bigger, this technology, due to being substantially reduced face contact during former collision, makes exhaust valve plate and the contact surface of stop significantly subtract
Few, substantially make produced noise between exhaust valve plate and limiting plate be reduced to Min..
