Description
Technical field
The utility model relates to a kind of compressor part, relates in particular to the valve board assembly of compressor.
Background technique
At present; Be main with the reed valve board structure in the valve board assembly that extensively adopts in the common crankshaft connecting rod type compressor; Like Fig. 1, Fig. 2 and shown in Figure 3; Valve board assembly comprises valve plate 1a, exhaust valve plate 5a, exhaust spring sheet 4a, snubber 3a, spacer 7a, air-intake valve plate 6a and air inlet spring sheet 8a; Offer exhaust port 11a and inlet hole 12a on the valve plate 1a, screw 2a is connected in first of valve plate 1a with the end of spacer 7a, snubber 3a, exhaust spring sheet 4a and exhaust valve plate 5a successively and goes up and fix with nut 21a, and the other end of exhaust valve plate 5a is over against exhaust port 11a; Air-intake valve plate 6a one end is fixed in straight pin 61a through air inlet spring sheet 8a on second of valve plate, and exhaust valve plate 5a and air-intake valve plate 6a all are shape fond of gossip.
The shape of the air-intake valve plate of valve plate is generally shape fond of gossip, in the course of the work can alternating bending, should play the effect that is sealed into pore in exhaust process; Also bear the function of bending repeatedly simultaneously; And with the lift snubber be single-point (or single line) bump, therefore the stressing conditions of this valve block is relatively poor, working life is shorter; In case compressor generation liquid hammer, air-intake valve plate also are more prone to fracture.
The model utility content
The utility model technical problem to be solved is to provide a kind of long service life reliable compressor valve board assembly to the above-mentioned state of the art.
The utility model technical problem to be solved is to provide a kind of assembling compressor valve board assembly efficiently easy to maintenance to the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of compressor valve board assembly; Comprise valve plate, exhaust valve plate and air-intake valve plate; Have exhaust port and inlet hole on this valve plate; Aforesaid exhaust valve plate is located at first of valve plate and can be opened and closed exhaust port; Aforesaid air-intake valve plate is located at second of valve plate and can be opened and closed inlet hole, it is characterized in that the middle part of said valve plate has a mounting hole, and a connector element passes this mounting hole and is arranged at described exhaust valve plate and air-intake valve plate on the valve plate together; Described exhaust port is arranged on the valve plate in the form of a ring and around aforesaid mounting hole, accordingly, described exhaust valve plate has the sealing surface of annular; Described inlet hole is arranged on the valve plate and around aforesaid exhaust port in the form of a ring, and accordingly, described air-intake valve plate in the form of a ring and the sealing surface with annular.
The described air-intake valve plate back side inwardly is provided with valve block seat and wave spring washer successively from outward, this valve block seat has the connector element of confession and runs through first mesopore that passes through, and this wave spring washer is resisted against on the sealing surface of air-intake valve plate.Air-intake valve plate only plays the effect that opens and closes air-breathing valve opening, and elastic force is born by the wavy spring packing ring, and air-intake valve plate can alternating bending, only does axial linear reciprocating motion, moves more reliable.
Further, the back side of said exhaust valve plate is provided with a ring-type snubber, and this ring-type snubber has the connector element of confession and runs through second mesopore that passes through.
For improving sealing; First mask of said valve plate have one with the first suitable annular groove of sealing surface of exhaust valve plate; The inside and outside both sides moulding of this first annular groove is the first interior sealed muscle and the first external sealed muscle of concentric ring, and described exhaust port then forms between the aforesaid first interior sealed muscle and the first external sealed muscle.
For improving sealing; Second mask of said valve plate have one with the second suitable annular groove of air-intake valve plate; This second annular groove bottom protrusion is provided with the second interior sealed muscle and the second external sealed muscle that is concentric ring; Said inlet hole then is arranged between the aforesaid second interior sealed muscle and the second external sealed muscle, and described exhaust port then is arranged in the zone that sealed muscle surrounds in second.
For making integral body compact more, reduce setting height(from bottom), after described valve block seat was installed on the valve plate, said valve block seat is positioned at second annular groove and the exterior edge face keeps flushing with the exterior edge face of valve plate.Further, described connector element is sunk screw and is equipped with nut that this sunk screw exterior edge face keeps flushing with the exterior edge face of said valve block seat.
The runner of said inlet hole from first of valve plate to second face diameter to the setting that slopes inwardly, and second mask that described inlet hole is positioned at valve plate has an aperture to become wide mouthful of big section.Generally has an isolation zone on the compressor cylinder cover; The isolation zone keeps apart the air inlet and the exhaust of compressor; The arranged outside of isolation zone circular arc is an air aspiration cavity; The inboard of isolation zone circular arc is set to exhaust cavity; If the inlet hole runner on this valve plate is not designed to the form of several angle, certainly will to reduce the volume (too small the stable of high pressure side air-flow that be unfavorable for of discharge chamber volume) of exhaust cavity, the internal diameter that perhaps increases suction valve chip comes corresponding with the position in air-breathing runner hole (suction valve chip is crossed conference air-breathing harmony is caused adverse effect) with external diameter.
Compared with prior art, the advantage of the utility model is: air-intake valve plate and exhaust valve plate are ring structure, and are arranged on the valve plate together with same connector element; Assemble easy to maintenance quick; Air-intake valve plate is only done axial linear reciprocating motion, can alternating bending, and the unit area impact force of air-intake valve plate is less; Whole stressed even, the working life and the reliability of operation that have prolonged air valve.
