Embodiment
Embodiment of the present utility model is set forth further below in conjunction with accompanying drawing:
As shown in Figures 1 to 8, a kind of air valve that the utility model provides, it is for membrane pump with pneumatic drive, comprise air valve main body 2531, valve core housing 2534, main valve plug 2536, changeover valve core 2532, left end cap 2539, right end cap 2538, silencing apparatus 2540, described air valve main body 2531 is provided with a valve core housing through hole 14, described valve core housing 2534 is placed in this valve core housing through hole 14 by seal ring 2535 sealing, and described main valve plug 2536 is placed in valve core housing 2534; Described air valve main body 2531 is also provided with a changeover valve core through hole 13, and described changeover valve core 2532 is placed in this changeover valve core through hole 13 by seal ring 2533 sealing; Described left end cap 2539, right end cap 2538 are secured by bolts in the two ends of air valve main body 2531 and are sealed by seal ring 2537 between the gentle valve body 2531 of left end cap 2539, right end cap 2538; Described silencing apparatus 2540 is connected to the bottom of air valve main body 2531 by exhaust port 1, exhaust port 2 20.
Described air valve main body 2531 is also provided with bolt fixing hole 1, bolt fixing hole 22, bolt fixing hole 33, and inlet hole 8, and air outlet hole 1, air outlet hole 2 10, and exhaust port 1, exhaust port 2 20, and vent 1, vent 25, vent 36, vent 47, vent 5 11, vent 6 12, vent 7 15, vent 8 16, vent 9 17, vent 10; Described vent 1, vent 47 are communicated to changeover valve core through hole 13; Described vent 25, vent 36 are communicated to vent 6 12, vent 7 15 more respectively by changeover valve core through hole 13; Described vent 5 11, vent 8 16 are communicated to vent 10; Described vent 9 17 is communicated to inlet hole 8.
Described left end cap 2539, right end cap 2538 are provided with gas flow.
Working procedure of the present utility model comprises: pressurized air enters air valve by inlet hole 8 and enters the side air chamber of membrane pump with pneumatic drive through main valve plug 2536 by air outlet hole 1, simultaneously feedback gas feeds back to changeover valve core 2532 by vent 10 and carries out commutating thus control bound core 2536 commutates, after commutation, pressurized air changes again and enters the opposite side air chamber of membrane pump with pneumatic drive to air outlet hole 2 10, and iterative cycles commutation like this controls the work of membrane pump with pneumatic drive.
