Specific embodiment
As shown in Figure 1 and Figure 5, the exhaust connection structure between compressor cylinder cover and housing of the present invention include cylinder head 4,
Cylinder head joint 2, exhaust connection 1, compressor exhaust pipe 3 and compressor housing 5.Cylinder head 4 is assembled in the movement of compressor
On, one end and the cylinder head 4 of cylinder head joint 2 are weldingly connected, and other end 2a is connected with exhaust connection 1, and end 2a is equipped with one
The straight pipe of measured length, the end of the straight pipe are equipped with limited step 2c（Please refer to Fig. 2 and Fig. 4）, connected with control exhaust
The insertion depth of take over 1.Compressor exhaust pipe 3 is welded on compressor housing 5, on compressor exhaust pipe 3, positioned at compression case
One end 3a of 5 inside of body is connected with exhaust connection 1, which is equipped with the straight pipe of certain length, and the end of the straight pipe is similary
Equipped with limited step 3c（Please refer to Fig. 2 and Fig. 3）, to control the insertion depth of exhaust connection 1.Exhaust connection 1 is
Equal diameter plastic tube, is made of engineering plastic materials, is typically polytetrafluoroethylene (PTFE), polyamide fiber material, has certain
Plasticity is easier to be inserted into.For currently used metal connecting tube, it can be more convenient that more soft connection is made
Pipe reduces the transmission that movement vibration passes through connecting tube.Meanwhile engineering plastic materials have certain damping, high-frequency vibration and make an uproar
Sound is converted into the interior energy of plastic tube through being easy to be dissipated in 1 transmittance process of exhaust connection, the high-frequency vibration that transfers and
Noise is small more than metal tube.Both ends 1a, 1a of exhaust connection 1 ' is equipped with the straight pipe of certain length, two straight pipes point
Cha Ru not be in the 2a ends of cylinder head joint 2 and endoporus set by the 3a ends of compressor exhaust pipe 3, insertion depth is respectively to /V
Until step 2c, limited step 3c（Please refer to Fig. 2, Fig. 3 and Fig. 4）.The outer diameter of exhaust connection 1 is slightly less than or waits respectively
Internal diameter in the 2a ends of cylinder head joint 2 and the straight pipe cylindrical surface at the 3a ends of compressor exhaust pipe 3, convenient for exhaust connection 1
Cylinder head joint 2 and compressor exhaust pipe 3 are inserted into respectively.
As shown in figure 4, after insertion exhaust connection 1, on the 2a ends straight pipe cylindrical surface of cylinder head joint 2, exhaust company
For take over 1 with squeezing out a circle toroidal cavity 2b in the outside wall surface of the matching part of cylinder head joint 2, groove 2b is extruded in row
In gas connecting tube 1, the entire circumferential direction on cylindrical surface is covered.The circumferential recess that exhaust connection 1 is arranged on cylinder head joint 2 is subject to
After 2b is squeezed, connect with because the protruding parts generated during crimp fit closely, playing exhaust on the internal face of cylinder head joint 2
Sealing and connection function between take over 1 and cylinder head joint 2.Cylinder head joint 2 is made of copper pipe, has good modeling
Property, convenient for squeezing out with larger depth without the toroidal cavity 2b that cracks.And exhaust connection 1 has centainly
Plasticity can form larger sealing surface between the two, ensure sealing.Certainly, it is close to further improve bonding strength and reinforcement
Sealing property, as needed also extrudable multiple groove 2b.Equally, as shown in figure 3, after insertion exhaust connection 1, arranged in compressor
On the 3a ends straight pipe cylindrical surface of tracheae 3, exhaust connection 1 is in the outside wall surface of the matching part of compressor exhaust pipe 3 with squeezing
Go out a circle toroidal cavity 3b, groove 3b is extruded in exhaust connection 1, covers the entire circumferential direction on cylindrical surface.Exhaust connection
Pipe 1 after the circumferential recess 3b that is subject to arrange on compressor exhaust pipe 3 is squeezed, on 3 internal face of compressor exhaust pipe because squeezing
The protruding parts for deforming and generating fit closely, and play the sealing between exhaust connection 1 and compressor exhaust pipe 3 and connection is made
With.Compressor exhaust pipe 3 is made of copper pipe, has good plasticity, convenient for squeezing out with larger depth without generating
The toroidal cavity 3b of crackle.And exhaust connection 1 has certain plasticity, can form larger sealing surface between the two,
Ensure sealing.Certainly, to further improve bonding strength and strengthening sealing performance, also extrudable multiple groove 3b as needed.
In present embodiment, the both ends connection structure of exhaust connection 1 is using the extruding circumferential recess in outside wall surface
Mode is attached and seals.And in actual use, can also only above-mentioned extruding be used in the either end of exhaust connection 1
The connection structure of circumferential recess.
