Abstract
The utility model discloses a cylinder cover sealing gasket with a lift limit function for a double-concave valve plate. A connecting strip with the same width as a vent valve sheet is reserved at the portion of the sealing gasket close to the vent valve sheet, and the middle portion of the connecting strip is bent towards the opposite side of the vent valve sheet. The cylinder cover sealing gasket with the lift limit function for the double-concave valve plate has the advantages that a shape the same as a stopper is directly pressed on the sealing gasket, the sealing gasket not only plays the role of sealing but also plays the role of limiting, the stopper of a vent valve is also saved, production efficiency is greatly improved, and production cost is lowered.
Description
[technical field]
The utility model relates to refrigeration compressor, specifically relates to the sealing gasket that uses in a kind of refrigeration compressor.
[background technique]
The refrigeration compressor exhaust valve plate is one of most critical parts of compressor; In compressor operation because of inhale, the exhaust frequency is high especially; So its Lift must limit in case too high its life-span of reduction of exhaust lift in exhaust process, existing refrigeration compressor generally is snubber to be installed reach its spacing purpose on valve plate.To process snubber installing and locating hole etc. at the groove of installation and processing snubber on the valve plate or on valve plate like this, therefore bring certain degree of difficulty, also strengthen simultaneously owing to the lift snubber that uses exhaust valve plate makes cost of production to processing.
[summary of the invention]
The utility model technical problem to be solved is to provide an installation spacing concave-concave valve plate of lift that has simple, that cost is low to use the cylinder cap sealing gasket.
The utility model solves the problems of the technologies described above through following technological scheme: a kind of concave-concave valve plate with lift position-limiting action is used the cylinder cap sealing gasket; A connection strap identical with the exhaust valve plate width is reserved at the position near exhaust valve plate of said sealing gasket, and the intermediate portion of this connection strap is crooked towards the exhaust valve plate opposition side.
The utility model has the advantages that: on sealing gasket, directly extrude the shape identical with snubber; This sealing gasket has not only played seal action but also played limit effect; Also saved the snubber of outlet valve, manufacturing efficiency obtains bigger raising, has also reduced cost of production.
[description of drawings]
Fig. 1 is that a kind of concave-concave valve plate with lift position-limiting action of the utility model is with cylinder cap gasket structure figure.
Fig. 2 is the A-A sectional view of Fig. 1.
[embodiment]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings so that those skilled in the art can better understand the utility model and can implement, but the embodiment that lifts not conduct to the qualification of the utility model.
Please consult Fig. 1 and shown in Figure 2 simultaneously; A kind of concave-concave valve plate with lift position-limiting action of the utility model is with the improvements of cylinder cap sealing gasket 1 with respect to existing sealing gasket: a connection strap 12 identical or close with the exhaust valve plate width is reserved at the position near exhaust valve plate at existing sealing gasket, and the intermediate portion of this connection strap 12 is crooked towards the exhaust valve plate place.The shape of this connection strap 12 is pressed into when sealing gasket 1 impact briquetting simultaneously.
The utility model sealing gasket is used in the installing of exhaust valve plate of concave-concave valve plate, and the position that suction valve chip and exhaust valve plate are installed in the suction of said concave-concave valve plate, exhaust two sides extrudes first groove and second groove respectively.Thickness and the shape with suction valve chip and exhaust valve plate is identical respectively with shape for the thickness of said first groove and second groove; Operator need only when assembling suction valve chip and exhaust valve plate and are placed in first groove and second groove suction valve chip and exhaust valve plate just passable respectively; After exhaust valve plate is installed; Directly the utility model sealing gasket 1 is installed in the exhaust valve plate outside; Exhaust valve plate is pushed down in the both sides of connection strap 12, and crooked position supply and exhaust valve block is reserved the exhaust space of certain position, thereby plays exhaust valve plate lift position-limiting action.
Claims (1)
1. the concave-concave valve plate with lift position-limiting action is used the cylinder cap sealing gasket; It is characterized in that: a connection strap identical with the exhaust valve plate width is reserved at the position near exhaust valve plate of said sealing gasket, and the intermediate portion of this connection strap is crooked towards the exhaust valve plate opposition side.
