Abstract
The utility model discloses a reciprocating compressor with a novel cylinder cover gasket, which comprises a cylinder cover and a valve plate. The cylinder cover gasket is installed between the cylinder cover and the valve plate and comprises three layers which are a first rubber layer, a metal layer and a second rubber layer in sequence from top to bottom. The first rubber layer and the second rubber layer are made of nitrile rubber, the metal layer is made of a cold rolled steel plate, a circle of elastic protrusions are arranged on the cylinder cover gasket, and the section of the elastic protrusions is in an arch shape. The metal layer is clamped between the two rubber layers to form the cylinder cover gasket of the reciprocating compressor, the cylinder cover gasket is reliable in structure, breakage of the cylinder cover gasket can be effectively avoided, the rubber layers are made of the nitrile rubber, the metal layer is made of the cold rolled steel plate, and the elasticity, hardness and tightness requirements of the gasket are guaranteed. The circle of elastic protrusions are arranged on the cylinder cover gasket, and the tightness of a component is improved after the gasket is assembled to be in place.
Description
Technical field
The utility model relates to the reciprocal compressor of small-sized refrigerating machine, is specifically related to the cylinder cover gasket of reciprocal compressor.
Background technique
The cylinder head of the compressor of reciprocating piston is equipped with the valve plate of a band exhaust valve plate usually, and cylinder head is generally aluminum casting, and suction valve chip and valve plate pad are housed between cylinder block and the valve plate, between cylinder head and valve plate, cylinder cover gasket is housed.Because the misoperation of compressor operation; Possibly cause that the pressure in the cylinder head chamber sharply increases suddenly; In some cases; In the exhaust cavity this surge pressure can cause the slip of cylinder cover gasket even breaks, cause the beyond retrieve destruction of cylinder cover gasket, and then influence the normal use of compressor.
The model utility content
The purpose of the utility model is to provide a kind of reciprocal compressor with novel cylinder cover gasket, this reciprocal compressor novel structure, long service life.
The utility model to achieve these goals, the technical solution of employing is:
Reciprocal compressor with novel cylinder cover gasket comprises cylinder head and valve plate, between cylinder head and valve plate, cylinder cover gasket is housed; Said cylinder cover gasket has three layers at least, and both sides is rubber layer about being positioned at, and is metal layer between the rubber layer.
Further, said cylinder cover gasket has three layers, is first rubber layer, metal layer, second rubber layer from top to bottom successively.
Further, said rubber layer is the rubber layer that nitrile butadiene rubber is processed, and metal layer is the cold metal layer that steel plate is processed that prolongs.
Further, a circle elastic heave is arranged on the said cylinder head gasket.
Further, said elastic heave cross section is arch.
The beneficial effect of the utility model:
The cylinder cover gasket of this kind reciprocal compressor is that two-layer rubber layer clips the layer of metal layer; Reliable in structure can effectively prevent the cylinder cover gasket fracture, and rubber layer is processed by nitrile butadiene rubber; Metal layer is processed by the cold steel plate that prolongs, and has guaranteed elasticity, hardness and the sealing requirements of pad.One circle elastic heave is arranged on the cylinder gasket, improved the sealing at this position after pad is seated.
Description of drawings
Fig. 1 is the partial structurtes schematic representation with reciprocal compressor of novel cylinder cover gasket.
Fig. 2 is the structural representation of cylinder cover gasket.
Fig. 3 is an A-A sectional drawing among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
In conjunction with Fig. 1 to Fig. 3; Reciprocal compressor with novel cylinder cover gasket comprises cylinder head 1 and valve plate 3, between cylinder head 1 and valve plate 3, cylinder cover gasket 2 is housed; Said cylinder cover gasket 2 has three layers, is first rubber layer 21, metal layer 22, second rubber layer 23 from top to bottom successively.First rubber layer 21, second rubber layer 23 are processed by nitrile butadiene rubber, and metal layer 22 is processed by the cold steel plate that prolongs, and a circle elastic heave 24 is arranged on the said cylinder head gasket 2, and elastic heave 24 cross sections are arch.
The cylinder cover gasket of this kind reciprocal compressor is that two-layer rubber layer clips the layer of metal layer; Reliable in structure can effectively prevent the cylinder cover gasket fracture, and rubber layer is processed by nitrile butadiene rubber; Metal layer is processed by the cold steel plate that prolongs, and has guaranteed elasticity, hardness and the sealing requirements of pad.One circle elastic heave is arranged on the cylinder gasket, improved the sealing at this position after pad is seated.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technician in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
