Abstract

The present invention belongs to the field of an air charging device, which particularly relates to a structure of a cylinder cover for a compressor. The present invention is characterized in that a flat end part with a defined area is manufactured at one end of a main body of a compressor body, a through hole is drilled in the compressor body, and one end is provided with an annular groove; one end of a cylinder sleeve with compression space formed in the inner part is provided with a flange of which the area is larger than that of the annular groove. When the cylinder sleeve is arranged in the through hole of the compressor body, the annular groove of the compressor body can form an oil path for cooling oil after the flange of the cylinder sleeve is matched with the flat end surface of the compressor body. The end part of a cylinder cover is provided with a flange with a defined area, which can be matched with the flange of the cylinder sleeve. A sealing pad is clamped in the flange which passes through the component to be fastened to the end part of the plane surface of the compressor body by a bolt. A valve body is arranged in the cylinder cover and can be telescopic in the cylinder sleeve. Because a compressor adopts the structure, the compressor can prevent the phenomenon of oil leakage of the oil path under the condition that cooling oil for cooling compressed air at the upper part of the cylinder and generating high temperature heat quantity flows, and simultaneously, the compressor can also prevent air with high temperature and high pressure in the compression space of the cylinder from leaking. The efficiency and the reliability of the compressor can be improved.

Description

The structure of compressor cylinder cover
Technical field
The invention belongs to compressor field, particularly relate to a kind of structure of compressor cylinder cover.
Background technique
Present known compressor is the equipment of compressed fluid, and this compressor can be divided into rotary compressor, reciprocal compressor, Scroll-type compressor etc. according to the mode of compressed fluid.When connecting power supply, just make motor produce driving force, and the driving force of motor generation is passed to compressor, in driven compressor, suck air, then compress exhausting air.
Fig. 1 is the compression member schematic representation of prior art compressor.It is by forming with lower member: fuselage 10, and extend and make blunt end part 12 by setting area at an end of main body 11, on main body, be shaped on through hole 13, and the annular groove 14 concentric with through hole 13; The end that the cylinder liner 22 of band compression volume 21 is housed in the cylinder 20 has the flange 23 of setting area; And cylinder liner 22 matches with fuselage through hole 13 and annular groove 14; The interior edge face of the cylinder head flat-top cover 31 of cylinder head 30 matches with the external diameter of the annular boss 24 of cylinder liner, and the one side at its flange 32 and the annular groove place on the fuselage main body 11 matches; A plurality of bolts 40 tighten together cylinder-head flange 32 and fuselage main body 11; Valve body 50 is made up of valve 51, spring 52, is contained in the cylinder head flat-top cover 31, by piston 70 compression cylinders, forms compression volume 21.
The blunt end part 12 of above-mentioned fuselage is to form a plane at an end of fuselage main body 11, and the through hole 13 of annular groove 14 and main body 11 is concentric, and bigger and the corresponding degree of depth arranged than the internal diameter of through hole 13.The external diameter of cylinder liner 22 matches with the internal diameter of the through hole of fuselage 13.The external diameter of cylinder liner flange 23 is littler than the internal diameter of the annular groove 14 of fuselage, and the inner cylindrical surface of the external cylindrical surface of cylinder liner flange 23 and lower plane and annular groove 14 and bottom surface thereof form the oil circuit F of cold oil like this.
Cylinder head flat-top cover 31 inner undersides are shaped on sealing with installation suitable thickness seal ring 60 between the last plane of groove 33 and the cylinder liner flange 23 that is mated, and material is flexible, and when usefulness bolt 40 was fastening, seal ring was compacted and seal.
The working condition of prior art compressor is as follows:
When the driving force of motor passes to piston 70, piston is just done straight reciprocating motion in the scope of the compression volume 21 of cylinder.Along with the variation in pressure of to-and-fro motion generation, by discharging again after the valve body 50 suction air compression.From the high temperature and high pressure gas that cylinder compression volume 21 is discharged, discharge through the exhaust port 34 of cylinder head one side.Because its cooling oil circuit F was formed by the side of fuselage groove 14 and bottom surface 12 external cylindrical surface and the following of cylinder-head flange 32 with cylinder liner flange 23, reveal easily so that be flowing in the oil of oil circuit F, the high temperature and high pressure gas of compression volume is also revealed easily, but also had the shortcoming that to adjust fitted position and change compression volume 21.
