Description
Technical field
The present invention relates to a kind of inner connecting structure of refrigeration compressor, specifically a kind of refrigeration compressor is with the elastic compression structure of cylinder and valve board assembly.
Background technique
Refrigeration compressor generally adopts cylinder and valve board assembly structure, with the function that realizes sucking low-pressure gas, discharges pressurized gas.Existing refrigeration compressor generally adopts structure as shown in Figure 1; Comprise component such as crankcase 1, valve plate pad 5, valve board assembly 6, cylinder head gasket 7, cylinder head 8, screw 9, stage clip 10, air suction silencer 11; Crankcase 1 is provided with exhaust noise silencing chamber 2 and cylinder 3; Cylinder 3 end faces are provided with screw 4, and screw 9 is screwed into the connection that screw 4 is realized between cylinder and the valve board assembly.As shown in Figure 2, screw 9 is fixed tightly in parts such as valve plate pad 5, valve board assembly 6, cylinder head gasket 7, cylinder head 8, air suction silencer 11 on the cylinder 3.During installation, be the anti-leakage that stops pressurized gas, screw 9 is the screw moment of torsion of needs 5～15Nm fixedly the time with cylinder 3.There is unavoidable defective in this assembly structure: because the distributed quantity of screw 9 is limited; General with 3～4, screw 9 and cylinder 3 are after tightening, and cylinder is easy to generate tightens distortion; According to measurement; Amount of deformation is at 2～8 μ m, and such amount of deformation is enough to influence the performance of refrigeration compressor, especially high-efficient compressor.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of sealability that can improve cylinder and valve board assembly, reduces the amount of deformation of tightening of cylinder, thereby strengthens the elastic compression structure of the refrigeration compressor of refrigeration compressor performance with cylinder and valve board assembly.
For solving the problems of the technologies described above; Refrigeration compressor of the present invention comprises crankcase, valve plate pad, valve board assembly, resilient pad, thread bush, cylinder head gasket, cylinder head, jump ring, muffler and air suction silencer with the elastic compression structure of cylinder and valve board assembly; Said crankcase is provided with cylinder; Said resilient pad is fixedly connected on the outer surface of said valve board assembly; The outside, end of said cylinder is provided with outside thread, and the inboard, end of said cylinder is provided with step hole, and said thread bush is provided with internal thread; After said valve plate pad, valve board assembly and resilient pad imported said cylinder step hole, said thread bush compressed from the outside and is fixedly linked through internal thread and said cylinder.
Above-mentioned refrigeration compressor is with the elastic compression structure of cylinder and valve board assembly, and said resilient pad is provided with fixed pan and contact surface, and said fixed pan is fixed tightly on the outer surface of said valve board assembly, and the end of said contact surface and said thread bush contacts.
The cylinder head structure of above-mentioned refrigeration compressor, said jump ring is provided with the buckle that inwardly turns over more than two.
The installation process of elastic compression structure of the present invention divided for three steps carried out: the first step, earlier the fixed pan of resilient pad is fixed tightly in the outer surface of valve board assembly, and modes such as available welding, bonding and riveted joint realize location and fastening; Again valve plate pad, valve board assembly, resilient pad are imported the cylinder step hole; Second step; Thread bush is imported cylinder outside thread rotation and tightens; The end of thread bush end compresses parts such as resilient pad, valve board assembly and valve plate pad when tightening, and the contact surface of resilient pad and the end of thread bush end are in contact condition during the thread bush rotation.Because the screw-down torque of thread bush can be controlled, thereby can guarantee the sealing between cylinder step hole, valve plate pad and the valve board assembly; Simultaneously, because resilient pad has the certain deformation ability, the impacting force that produces when thread bush is tightened can be evenly distributed between cylinder outside thread and the thread bush internal thread very much, and the amount of deformation of cylinder can significantly reduce; In addition, during the thread bush rotation, contacting of end and resilient pad is the curved surface contact, so just can avoid producing smear metal, improves installation technology property.The 3rd step; Parts such as cylinder head gasket, cylinder head, muffler, air suction silencer are clamped on the surface of valve board assembly with jump ring; The end of the set buckle that inwardly turns over more than two chucking thread bush on jump ring during assembling; Cylinder head gasket is processed with the rubber elastomeric material, can guarantee good seal between cylinder head and the valve board assembly after compressing.Thereby elastic compression structure of the present invention can guarantee the sealing of cylinder and valve board assembly, can effectively reduce cylinder deformation again, thereby improves the efficient of compressor.

Embodiment
As shown in Figure 3; The cylinder head structure of refrigeration compressor of the present invention comprises crankcase 12, valve plate pad 16, valve board assembly 17, resilient pad 18, thread bush 19, cylinder head gasket 21, cylinder head 22, jump ring 25, muffler 23 and air suction silencer 24; Crankcase 12 is provided with cylinder 13; The outside, end of cylinder 13 is provided with outside thread 14, and the inboard, end of cylinder 13 is provided with step hole 15, and thread bush 19 is provided with internal thread 20.Resilient pad 18 is provided with fixed pan 31 and contact surface 32 (please consulting Fig. 4 simultaneously).
Like Fig. 3 and shown in Figure 4; The installation of refrigeration compressor cylinder head of the present invention divided for three steps: the first step; Fixed pan 31 with resilient pad 18 is fixed tightly on the outer surface of valve board assembly 17 earlier; Modes such as available welding, bonding or riveted joint realize location and fastening, and are fricton-tight relatively when assembling between resilient pad 18 and the valve board assembly 17; Again valve plate pad 16, valve board assembly 17, resilient pad 18 are imported cylinder step hole 15.Second step imported thread bush 19 outside thread 14 of cylinders 13 and tightens, and the end 28 of thread bush 19 compresses parts such as resilient pad 18, valve board assembly 17 and valve plate pad 16 when tightening.Because the screw-down torque of thread bush 19 can be controlled, thereby can guarantee the sealability of valve board assembly 17 and cylinder 13.Simultaneously, because resilient pad 18 has the certain deformation ability, on impacting force distributed the circumference flank of thread very equably when thread bush 19 was tightened, the amount of deformation of cylinder 13 can significantly reduce.In addition, during owing to thread bush 19 rotations, the smooth surface on the contact surface 32 contacts with end 28, produces smear metal when avoiding sliding between end 28 and the contact surface 32, improves installation technology property.The 3rd step; Earlier cylinder head gasket 21 is adjacent on valve board assembly 17; With jump ring 25 cylinder head 22, muffler 23, air suction silencer 24 parts are clamped on the surface of valve board assembly 17 again; Jump ring 25 is provided with two buckles that inwardly turn over 27, and buckle 27 tightens on the end 26 of thread bushs 19 during assembling; Cylinder head gasket 21 usefulness rubber elastomeric material are processed, and can guarantee good seal between cylinder head 22 and the valve board assembly 17 after compressing.
The present invention had both guaranteed the sealability of linkage structure owing to adopt technique scheme, had effectively reduced cylinder deformation again, thereby improved the efficient of compressor.
