Exhaust pipe is connected to, one end of the exhaust pipe connects gas-tpe fitting, is fixedly connected with spring on the inner wall of the second shell, institute
The end for stating spring is fixedly connected with spool, and the spool is rubber block, and the left surface of the spool is taper surface, the spool
Left surface be close to the end of air inlet pipe, the left surface of the spool is fixedly connected with cylinder, and the air inlet pipe is equipped with knob,
The knob runs through exhaust pipe, and the knob, which is located at exhaust pipe inside, is equipped with cam, and the end of the cylinder is resisted against cam.
Preferably, the longitudinal section of the spool is circle, the angle of inclination of the left side conical surface of the spool 25 ° -45 ° it
Between.
Preferably, the cylinder is plugged in spool, and the end of the cylinder is arc-shaped.
Preferably, the junction of the first shell and second shell is equipped with sealing ring.
Preferably, the spring is no less than four groups.
Compared with prior art, the beneficial effects of the utility model are：The utility model structure novel, it is easy to operate, lead to
Setting spring is crossed, spool is made firmly to be adjacent to the end of air inlet pipe under the action of spring force, so as to block air-flow, works as needs
During exhaust, by turning knob, the cam rotation of knob drive at this time, cam promotes cylinder to move right, so that spool is whole
It moving right, achievees the effect that exhaust, continue adjusting knob, spool resets under the action of the spring, so as to block air-flow, exhaust
Spool will not be caused to wear in the process, spool service life is long, and the junction of first shell and second shell is equipped with sealing ring,
Good seal performance has very high practicability, and greatly improve a kind of adjustable exhaust valve uses functionality, ensures that it makes
With effect and utilization benefit, it is suitble to be widely popularized.
