Abstract
The invention discloses a cylinder head structure of a refrigeration compressor. The cylinder head structure of the refrigeration compressor comprises a crank case, a valve plate spacer, a valve plate assembly, an elastic spacer, a thread bushing, a cylinder cover spacer, a cylinder cover, a clamp spring, an exhaust silencer and a suction silencer, wherein the crank case is provided with a cylinder, the outer side of the end part of the cylinder is provided with an external screw thread, the inner side of the end part of the cylinder is provided with a step hole, and the thread bushing is provided with an internal screw thread. By adopting the cylinder head structure disclosed by the invention, sealing property of a cylinder head can be guaranteed, and deformation when the cylinder head is screwed down can be effectively reduced, thus efficiency of the compressor is improved.
Description
Technical field
The present invention relates to a kind of linkage structure of refrigeration compressor, specifically a kind of cylinder head structure that is applied to refrigeration compressor.
Background technique
The function that refrigeration compressor is realized sucking low-pressure gas, discharged pressurized gas through cylinder head.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 installation that screw 4 is realized cylinder head.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 sealing function that can guarantee cylinder head, can realize the cylinder head structure of the refrigeration compressor that the amount of deformation when cylinder head is tightened can significantly reduce again.
For solving the problems of the technologies described above; The cylinder head structure of 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; Said crankcase is provided with cylinder; 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.
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 present invention is owing to adopted technique scheme; Two steps of time-division are installed carries out; The first step: earlier valve plate pad, valve board assembly are imported the inboard step hole in cylinder end; Resilient pad and valve board assembly are adjacent to again, at last thread bush are imported the outside thread of cylinder and tighten, the thread bush end compresses parts such as resilient pad, valve board assembly and valve plate pad when tightening.Because the screw-down torque of thread bush can be controlled, and can guarantee the sealing of valve board assembly and cylinder; Simultaneously, because resilient pad has the certain deformation ability, on impacting force distributed the circumference flank of thread very equably when thread bush was tightened, the amount of deformation of cylinder can significantly reduce.Second step: the surface that parts such as cylinder head gasket, cylinder head, muffler, air suction silencer is clamped on 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.Therefore, structure of the present invention can guarantee the sealability of cylinder head, the amount of deformation in the time of effectively reducing cylinder head again and tighten, thus improve 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.
Like Fig. 3 and shown in Figure 4; The installation first step of refrigeration compressor cylinder head of the present invention: earlier valve plate pad 16, valve board assembly 17 are imported the inboard step hole 15 in cylinder 13 ends; Again resilient pad 18 and valve board assembly 17 are adjacent to; At last thread bush 19 is imported the outside thread 14 of cylinders 13 and tighten, 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.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.
Like Fig. 3 and shown in Figure 4; Second step of installation of refrigeration compressor cylinder head of the present invention: 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 a plurality of 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 cylinder head owing to adopt technique scheme, had effectively reduced cylinder deformation again, thereby improved the efficient of compressor.
