Abstract
The utility model discloses a kind of refrigeration compressor ventilating valve block limiter, including fixed part and bending section, one end of bending section is fixedly connected with one end of fixed part, bending section is curved platy structure, fixed part is planar panel structure, the stepped connection in fixed connection place of fixed part and bending section and the upper edge of the upper surface higher than junction bending section of fixed part, the upper surface of fixed part forms ladder with the upper edge of bending section, projection is fixed with the extrados of the bending section other end, the thickness of projection is highly equal with ladder.Existing freezer compressor exhaust valve plate is that open degree is too big when preventing exhaust valve plate from opening, stopping means will be typically set, but produced noise is larger when being collided with valve plate and limiting plate when existing freezer compressor exhaust valve plate is opened and closed, to be solved in the utility model is noise produced when reducing or eliminating exhaust valve plate with valve plate and spacing collision as much as possible.
Description
Technical field
The utility model is related to a kind of Parts of Compressor of refrigeration plant, more particularly to a kind of refrigeration compressor ventilating valve
Piece limiter.
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 refrigerant in system, the conveying of refrigerant is to lean on the suction of compressor, exhaust valve plate to open and close and carry out, and it is opened
Tongue with the process valve block closed is acted on by alternate load, as same cantilever Beam swings up and down one in opening process
Noise can be produced when sample, making contact between valve block and valve plate and valve block and limiting plate, it is produced in refrigeration compressor
Noise essentially from compressor electric motor operation sound, compressor is inhaled, refrigerant is under stress in suction, exhaust process for exhaust valve plate
Produced airflow noise and compressor inhale, exhaust valve plate and valve plate and valve block with limiting plate collision when produced impact sound,
These sound are all the noises environmentally undesirable to people, for the noise produced by exhaust valve plate and limiting plate, are hit same
Hit that the lower produced noise of power effect is different with valve block tongue and limiting plate contact area size, shock contact area is got over
Greatly, the power for being produced 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 it is too big, stopping means will be typically set, but the exhaust valve plate stopping means of existing freezer compressor is for example spacing
Plate is not all entirely capable of eliminating noise produced when being collided with valve plate and limiting plate when exhaust valve plate is opened and closed, this practicality
Novel photo the characteristics of domestic refrigerator, air-conditioning etc. have noise low, greatly meets user's than limiter of the prior art
Demand.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided the pressure used on a kind of refrigeration plant
Contracting machine exhaust valve plate limiter, to solve existing refrigeration plant during work, the technology that the noise of generation is big is asked
Topic.
The technical solution adopted in the utility model is as follows：
It is described the utility model discloses a kind of refrigeration compressor ventilating valve block limiter, including fixed part and bending section
One end of bending section is fixedly connected with one end of the fixed part, and the bending section is curved platy structure, the fixation
Portion is planar panel structure, the stepped connection in the fixed connection place of the fixed part and the bending section and the fixed part
Higher than the upper edge of bending section described in junction, the upper surface of the fixed part is formed with the upper edge of the bending section for upper surface
Ladder, is fixed with projection on the extrados of the bending section other end, the height phase of the thickness of the projection and the ladder
Deng.This design not only causes exhaust valve plate and limiter when contacting by traditional bump contact, is contracted to only
One fritter face contacts, it might even be possible to reaches a contact, significantly reduces contact noise.
Further, in order to enable exhaust valve plate with limiter uniform force when contacting, will not damage
Bad exhaust valve plate, projection is the solid projection of round pie, the axis of bending section by round pie projection the center of circle.
Further, in order to prior art on exhaust valve plate design match, and stress it is well-balanced, be easy to peace
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, it is fixed in order to Compressor Air Exhaust Valve Plate limiter can be fixed into assembling with compressor
The other end in portion is provided with through hole, and the axis of through hole intersects vertically with the axis of fixed part.
Because the noise that refrigerator is produced is mainly produced by compressor, and the noise source of compressor is mainly compressor
Motor rotation when it is produced and inhale, it is produced during air current flow in exhaust valve plate and inhale, exhaust valve plate open and close into
Produced strike note when being collided with valve plate and limiting plate, and produced noise when being collided with limiting plate of exhaust valve plate with itself and
The area of collision is relevant, and noise produced when the bigger exhaust valve plate of area is collided with limiting plate is collided under the effect of same power
Also bigger, face contact when this technology is due to by original collision is substantially reduced, and exhaust valve plate is subtracted significantly with the contact surface of limiter
It is few, noise produced between exhaust valve plate and limiting plate is reduced to Min..

It is limited to following examples.
Embodiment 1
As depicted in figs. 1 and 2, present embodiment discloses a kind of refrigeration compressor ventilating valve block limiter, including fixed part 1
With bending section 2, one end of bending section 2 is fixedly connected with one end of fixed part 1, and bending section 2 is curved platy structure, fixed
Portion 1 is the upper surface of planar panel structure, the stepped connection in the fixed connection place 5 of fixed part 1 and bending section 2 and fixed part 1
Higher than the upper edge of the bending section of junction 5, the upper surface of fixed part 1 forms ladder with the upper edge of bending section 2, and bending section 2 is another
Projection 3 is fixed with the extrados of one end, the thickness of projection 3 is highly equal with ladder, projection 3 is that round pie is solid convex
Block, the axis of bending section 2 by round pie projection 3 the center of circle, the other end of bending section 2 is ovalize at 2.1, projection 3
In the top of oval plate face 2.1, the axis of bending section 2 passes through the focus of oval plate face 2.1, and the other end of fixed part 1 is provided with
Through hole 4, axis and the axis of fixed part 1 of through hole 4 intersect vertically.
Embodiment 2
It is identical with the technical characteristic in embodiment 1, only difference is that, the shape of projection can be designed as rectangle
Or other shapes with the matching of exhaust valve plate in the prior art.
