Abstract
The invention discloses a valve plate for a refrigerator compressor. The valve plate comprises a main body, wherein the fitting surface of the main body and a peripheral air cylinder cover gasket is provided with a plurality of grooves, and the grooves are positioned at the periphery of a high-pressure chamber generated when the main body works. According to the invention, the improved scheme that the periphery of the high-pressure chamber on the main body is provided with the grooves is adopted, so that when the air cylinder cover and an air cylinder are in press fit, the air cylinder cover gasket at the surface of each groove is micro-deformed and is pressed into the grooves by press force, and the seal property and partial tensile strength of the air cylinder cover gaskets are increased further, thus the air cylinder cover gaskets of the refrigerator compressor which are made of soft materials, especially the traditional NI-2085G material can be ensured not to be cracked due to pressure difference generated in work. The valve plate for the refrigerator compressor provided by the invention has the advantages that the valve plate has a simple and reasonable structure, the seal property of the compressor is improved, the integral service life is prolonged, the production cost is lowered, and the valve plate serving as an accessory for the refrigerator compressor is widely applied.
Description
Technical field
The present invention relates to a kind of compressor for refrigeration accessory, particularly a kind of compressor for refrigeration valve plate.
Background technique
Compressor for refrigeration generally is made up of housing, motor, exhaust valve component, control apparatus (starter and heat protector) and cooling system; wherein exhaust valve component comprises cylinder head again, has the cylinder that inlet hole and the valve plate of exhaust port, the cylinder cover gasket that cooperates with valve plate and the inside are equipped with piston and connecting rod; its assemble sequence is cylinder head, cylinder cover gasket, valve plate, valve plate pad, cylinder from top to bottom, and whole compacting does not have gas leakage.Piston is by motoring to-and-fro motion in cylinder, realizes the do action of air-breathing, the exhaust of compressor assembly.In addition, because the action of exhaust can cause producing the air pressure pressure change near the valve plate exhaust port, can form hyperbaric chamber.
Cylinder cover gasket is an important sealed member, the soft sealing material of general employing, the NI-2085G that use more, the NI-2085G reasonable price, good with the POE oil compatibility, but Tensile strength is lower slightly, like this, the cylinder cover gasket of described hyperbaric chamber periphery is then torn because of pressure difference changes the impact force that produces easily, thereby loses efficacy gas leakage.The method that solves is to change soft cylinder cover gasket into steel plate washer that the surface adds coating at present, though this has prevented the pad fracture, but its surfacing and POE oil compatibility are poor, and cost is high more than 100% than the NI-2085G material, so regardless of still being that cost of production is considered from sealing effect, this alternative is all not ideal.
Summary of the invention
Purpose of the present invention is for a kind of compressor for refrigeration valve plate is provided, and it has when cooperating with soft cylinder cover gasket, can prevent the characteristics that it ruptures because of pressure difference.
The solution that the present invention solves its technical problem is:
The compressor for refrigeration valve plate, it comprises body, the cylinder cover gasket faying surface of described body and peripheral hardware is provided with some roads groove, the hyperbaric chamber periphery that described groove produces when being positioned at this body running.
As further improvement in the technical proposal, described groove cross section is 0.3mm * 0.3mm.
As further improvement in the technical proposal, described groove and body are formed in one.
The invention has the beneficial effects as follows: the present invention adopts the improvement project of the peripheral machined grooves of hyperbaric chamber on body, make in cylinder head and cylinder pressing, the cylinder cover gasket of groove surfaces can produce micro-strain and compacted defeating to groove, the sealability and the local tensile strength of cylinder cover gasket have further been increased, even can guarantee that therefore compressor for refrigeration adopts flexible material, the pressure difference fracture that the cylinder cover gasket of particularly traditional NI-2085G material also can not produce because of when work, so both improved the sealing of compressor, prolong bulk life time, reduced cost of production again.
In addition, groove and body in the present invention are formed in one, and technology is simple, need not additionally to increase processing technology, and good with existing compressor interchangeability.
The present invention is simple and reasonable, can prevent when cooperating with soft cylinder cover gasket that it from rupturing because of pressure difference, has improved the sealing of compressor, has prolonged bulk life time, has reduced cost of production, is widely used as the accessory of compressor for refrigeration.
Description of drawings
The present invention is further illustrated below in conjunction with drawings and Examples.
Fig. 1 is that integral shaft of the present invention is surveyed schematic representation;
Fig. 2 is the present invention and stereochemical structure partial schematic sectional view after cylinder head, cylinder cover gasket cooperate;
Fig. 3 is the present invention when being assembled on the compressor for refrigeration, the sectional view of the exhaust valve component of compressor for refrigeration.
Embodiment
With reference to Fig. 1～Fig. 2, the compressor for refrigeration valve plate, it comprises body 2, employing NI-2085G material cylinder cover gasket 5 in the cylinder cover gasket 5(present embodiment of described body 2 and peripheral hardware) faying surface is provided with some roads groove 1, the hyperbaric chamber periphery that described groove 1 produces when being positioned at body 2 work.Particularly, in the present embodiment, described groove 1 has 4 roads, be respectively: be positioned at exhaust valve port both sides minor face the side groove, be positioned at the bending groove and the low groove on long limit, exhaust valve port both sides, wherein the track of side groove and low groove is straight line, the track of bending groove is bent into a fillet, and the both sides angle is 130
o, described fillet is coated on the periphery of the suction port 4 of body 2.Such groove 1 distributing position all is when originally adopting conventional NI-2085G material as cylinder cover gasket 5, its weakest, the easiest position of rupturing because of impact.Certainly, also can add or reduce the quantity of groove 1 or change its distributing position according to actual conditions, whole assembly is assembled after, the weak location that is fitted in the cylinder cover gasket 5 of hyperbaric chamber periphery originally all can be embedded in the groove 1.
Be further used as preferred embodiment, described groove 1 cross section is 0.3mm * 0.3mm.Because general NI-2085G valve plate pad 5 thickness are 0.5mm, therefore, make its small embedded part that can hold cylinder cover gasket 5 at the square groove 1 of this preferred 0.3mm * 0.3mm, can guarantee the structural strength of body 2 itself again.
Be further used as preferred embodiment, described groove 1 is formed in one with body 2.Particularly, described one-body molded mode is meant powder metallurgy sintered.
With reference to Fig. 3, after the present invention is assembled on the compressor for refrigeration, when cylinder 3 carries out the exhaust action, compression back pressurized gas enter in cylinder head 7 hyperbaric chambers through exhaust port 6 at short notice, and owing to use the screw close-coupled between cylinder head 7 and the cylinder 3, its tension moment can allow cylinder head 7 compress cylinder cover gasket 5 and make it to be embedded in the groove 1 of the present invention, and this allows the anti-exhaust pressure impact property of script cylinder cover gasket 5 weak parts improve greatly, and has also guaranteed sealing.
More than be that better embodiment of the present invention is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
