Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail:
Embodiment 1, in conjunction with Fig. 1 and Fig. 2, a kind of novel upper bracket improving compressor noise, including upper bracket body 1 and
Valve block 2, the center of described upper bracket body 1 upper end, there is the mounting seat 3 for assembling drive shaft 10, the dress in mounting seat 3
Distribution is extended to the bottom of upper bracket body 1 by its upper end.Described upper bracket body 1 is positioned at the part outside mounting seat 3, has
The hole venting one's pent-up feelings 4 of up/down perforation, described hole 4 venting one's pent-up feelings is positioned at the side of mounting seat 3 and is circular port.It is positioned at upper end, described hole venting one's pent-up feelings 4
Upper bracket body 1 on be provided with a noise reduction ring 5, the bottom wheel profile of the end face of described noise reduction ring 5 is straight line, noise reduction ring 5
Overhead pulley profile be curved line.Described noise reduction ring 5 is enclosed within the outside in hole 4 venting one's pent-up feelings, the axis in described hole 4 venting one's pent-up feelings and noise reduction ring 5
Dead in line, the bottom of noise reduction ring 5 is fixedly linked integral with upper bracket body 1.
Described valve block 2 is arranged on the upper surface of upper bracket body 1, and is positioned at the side of mounting seat 3, one end of valve block 2 with
Upper bracket body 1 connects by rivet is fixing, and the other end of valve block 2 is positioned at the top in hole 4 venting one's pent-up feelings, can cover in hole 4 venting one's pent-up feelings.
When the gases at high pressure of the cylinder body being positioned at below upper bracket body 1, when hole 4 of feeling elated and exultant upwards is discharged, valve block 2 upwards can be pushed up
Rising, valve block 2 is not when by External Force Acting, and one end near hole 4 of feeling elated and exultant of valve block 2, covering is at the upper table of noise reduction ring 5
Face.The strip foil that described valve block 2 is made up of silicon steel, has fabulous rigidity, at the high pressure discharged by hole 4 of feeling elated and exultant
Gas can be bent upwards, and after gases at high pressure are discharged, valve block 2 recovers deformation and again covers the upper surface at noise reduction ring 5.
Described valve block 2 be provided above bluff piece 6, one end of bluff piece 6 and valve block 2 pass through riveting away from the one end in hole 4 venting one's pent-up feelings
Following closely be connected fixing with upper bracket body 1, the other end of bluff piece 6 is positioned at the top in hole 4 venting one's pent-up feelings and is upturned, and described bluff piece 6 leans on
One end and the valve block 2 in nearly hole 4 of feeling elated and exultant have gap between the one end in hole 4 of feeling elated and exultant.Bluff piece 6 can prevent gases at high pressure by valve block
The 2 one end jack-up near hole 4 of feeling elated and exultant are too high, and meanwhile, compressor is in work process, and valve block 2 wants successive altofrequency ground quilt
Jack-up, if jack-up excessive height is easily caused the fatigue failure of valve block 2, valve block 2 is played the effect of position limitation protection by bluff piece 6.
Described compressor in the course of the work, incite somebody to action, and valve block 2 is positioned at above noise reduction ring 5 by the high voltage pulse gas in cylinder body 7
One end jack-up, valve block 2 recovers deformation after gases at high pressure are discharged, drops down onto the upper surface of noise reduction ring 5, with the upper surface of noise reduction ring 5
Collide generation abnormal sound.On the upper bracket body being not provided with noise reduction ring 5, valve block 2 and upper bracket body are positioned at hole 4 venting one's pent-up feelings
The planar section collision at top, face and face collide and produce whip the strike note that noise is bigger.This novel upper bracket is originally
Body 1 is being positioned at top, hole 4 venting one's pent-up feelings increase noise reduction ring 5, and when falling after rise, the base plane of valve block 2 occurs with the upper surface of noise reduction ring 5
Collision, due to face and linear contact lay, the strike note therefore produced effectively reduces, thus reduces the noise of compressor.
Embodiment 2, in conjunction with Fig. 2 and Fig. 3, a kind of pumping, including cylinder body 7, undersetting 9 and drive shaft 10, described cylinder body 7
Being arranged above above-mentioned a kind of novel upper bracket improving compressor noise, the top of described drive shaft 10 is positioned at mounting seat 3
Pilot hole in.Described drive shaft is positioned at the part of cylinder body 7 and is provided with offset piston 8, and the outside of offset piston 8 is cased with piston
Ring 11.Drive shaft 10 is positioned at the shaft shoulder above offset piston 8 and is attached to the bottom of above-mentioned novel upper bracket, and drive shaft 10 is positioned at bias
The shaft shoulder below piston 8 is attached to the top of undersetting 9.Reduce drive shaft 10 the shaft shoulder respectively with novel upper bracket and undersetting 9
Between gap, increase the area in axial thrust face of drive shaft 10, can effectively reduce the beat of drive shaft 10, reduce compression
The strike note that machine beat causes.Effectively reduce the generation of compressor operation abnormal sound, promote the quality of compressor.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above,
Change that those skilled in the art are made in essential scope of the present utility model, retrofit, add or replace, also should
Belong to protection domain of the present utility model.
