The tilting end in portion is respectively connected with a lengthening part, and the lengthening part is specifically made of rake and horizontal part, the rake
Top is connect with the tilting end in the wing portion, and the other end is connect with one end of the horizontal part, and the horizontal part is far from described
Horizontal plane where the bottom of one end of rake is the bottom of horizontal plane and the horizontal plane and the tail portion is same level, institute
The rib of the rib and the tail portion of stating horizontal part is fillet setting, is offered at the top of the valve plate corresponding with the tail portion
First groove is also provided with the second groove corresponding with two tongues, the top of the valve plate at the top of the valve plate
Be also provided with third groove corresponding with the horizontal part, each third groove can respectively with horizontal part corresponding with its
Interference fit, first groove, the second groove and third groove are interconnected.
Further, the same side of the tailgate is arranged in two tongues and the central symmetry about the tailgate is set
It sets, constitutes π type, the tailgate is arranged in first groove, and two tongues are arranged in second groove, and institute
The junction that states tailgate not and may pass through the first groove and the second groove enters in the second groove.
Further, open up that there are two through the valve plate and row corresponding with two tongues in second groove
Stomata.
Further, each one end of the tongue far from the tailgate can effectively seal the corresponding exhaust
Hole.
Further, two air inlets for running through the valve plate are also provided at the top of the valve plate.
Further, the side wall of first groove, second groove and the third groove is vertical wall.
Further, four steps at the top of the valve plate offer the mounting hole for running through the valve plate.
Further, the tail portion is arranged in the top of the tailgate and is fastened in first groove, two water
Flat portion is fastened in the corresponding third groove respectively and is mutually interference fitted.
The present invention is had the advantage that compared with prior art the present invention provides a kind of combination of refrigeration compressor valve plate, is led to
Cross lengthening part and multiple grooves setting avoid conventionally employed screw it is fixed when at work damage easy to fall off the drawbacks of, pass through
The setting of tail portion, rake and horizontal part in the groove that entire limit plate is fastened on valve plate, and then avoids only
The drawbacks of by screw connection limit plate and valve plate, and the part that the compressor entirety for reducing equipment after screw is omitted is a
Number；By the setting of fillet, it is easily installed equipment, reduces installation difficulty；It can be effectively prevented from by the multiple wing portions of setting more
A valve block needs the drawbacks of multiple limit plates, and when each wing portion one lengthening part of correspondence, limit plate can integrally be added by multiple
The cooperation of long portion and tail portion carries out card and sets installation, greatly improves stabilization of equipment performance.
