Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1, according to compressor valve of the present utility model, comprising: valve seat 20; Valve gap 10, comprise exhaust cavity 11 and air-inlet cavity 12, valve gap 10 is connected with valve seat 20, be provided with the first vent 111 on the exhaust cavity 11, the first vent 111 is used for being connected with the relief opening 21 of compressor, being provided with the second vent 121, the second vents 121 on the air-inlet cavity 12 is used for being connected with the intakeport 22 of compressor; Valve block 30, movable relief opening 21 places that are arranged on the valve seat 20 are used for opening or sealing relief opening 21; Valve rod 40, intakeport 22 places that are arranged on movably valve seat 20 are used for opening or sealing intakeport 22.The air valve of this programme is compared with existing piston compressor, and simple in structure, part is few, and assembling is easy, and reliability is high.
Referring to Fig. 1 and Fig. 6, valve rod 40 arranges intakeport 22 places of valve seat 20.Compressor valve also comprises the return unit 42 that is returned to closed state after making valve rod 40 air-breathing.Preferably return unit 42 is spring, an end of valve rod 40 and valve seat 20 phase clampings, and the other end of valve rod 40 is provided with nut 41 movably, and the two ends of spring connect with nut 41 and valve seat 20 respectively.Spring structure is simple, and is easy for installation.
Referring to Fig. 6, valve rod 40 is the frustum face with the surface of contact of intakeport 22.So both can guarantee the unobstructed of air inlet, in the time of also can guaranteeing to seal simultaneously, the sealing area be larger, and sealing effect is better.
Referring to Fig. 1 to Fig. 5, Fig. 7, relief opening 21 places that valve block 30 is arranged on the valve seat 20 seal relief opening 21.Be provided with the positive stop lug boss 112 for restriction valve block 30 bend angle in the exhaust cavity 11.Positive stop lug boss 112 is arc with the surface of contact of valve block 30.
Referring to Fig. 1, valve seat 20 is the exterior edge face of compresser cylinder.Valve seat 20 is not independent part body, makes air valve structure simpler.
Referring to Fig. 3, be provided with valve block mounting hole 31 on the valve gap 10, valve block 30 is connected with valve gap 10 by valve block mounting hole 31.
