Compared with the existing technology, a kind of combined type air inlet and exhaust valve of water hammer-resistant structure described in the utility model has following
Advantage：
(1) a water hammer-resistant flap, when the pressure of exhaust reaches certain value, waterproof are added in air bleeding valve bottom
Hammer flap can be blown afloat, since (specifically, position-limiting action is by taking over upper end with pallet contact site for the position-limiting action of pallet
Point), the position that water hammer-resistant flap stops after blowing afloat can be such that circulation area in valve body greatly reduces, to which mitigation of gases is discharged
Speed, that is, slow down the speed that fluid streams in pipeline bump against, greatly reduce water hammer intensity and achieve the purpose that water hammer-resistant.
(2) cushion pad is added on the pallet of valve body, floating ball and valve body contact can be avoided completely and bumped against, to which protection is floating
Ball；At the same time, since cushion pad and floating ball contact position are placed up recessed cambered surface, this fairshaped design can be prevented
Only floating ball is blown afloat in valve exhaust phase by original air in valve, and then block at spout seat and spout seat sealing ahead of time (and
Water level promoting under abnormal condition, which floats floating ball, to be blocked at spout seat and spout seat sealing)；In addition, cushion pad is arranged to
The mode (bolt, threaded hole are connect) being detachably connected with valve body, can both meet the effect of fixed cushion pad, prevent cushion pad quilt
Airflow scouring falls off, and can facilitate the replacement after cushion pad breakage.
(3) floating ball is oriented to upward, ensure that the concentricity of sealing surface and floating ball when floating ball rises, and then ensure sealing.
(4) water hammer-resistant flap is set as " umbrella " type, has better fluid curve, effectively prevent generating vortex when air inlet,
Increase drag reduction when being vented simultaneously and blows afloat the required pressure of water hammer-resistant flap.

Concordantly.
The course of work of the present embodiment is：
In use, when pipeline needs a large amount of exhausts, gas is discharged by the air bleeding valve of the present embodiment, with subtracting for gas
Few, water level rises in valve body 1, since buoyancy drives floating ball 2 to rise, is sealed at 3 when floating ball 2 rises to spout seat, spout
Seat sealing 3 is compressed, and is formed sealing, is prevented fluids within pipes from leaking out.When the pressure of exhaust reaches certain value, water hammer-resistant
Flap can be blown afloat, since (specifically, position-limiting action is by taking over upper end with pallet contact site for the position-limiting action of pallet
Point), the position that water hammer-resistant flap stops after blowing afloat can be such that circulation area in valve body greatly reduces, to which mitigation of gases is discharged
Speed, that is, slow down the speed that fluid streams in pipeline bump against, greatly reduce water hammer intensity and achieve the purpose that water hammer-resistant.
When forming negative pressure in pipeline, under needing a large amount of air inlets, floating ball 2 that can be inhaled because of the effect of pressure, bulk gas
Just from pipeline in intake line, is prevented from spout seat 4 because negative pressure is damaged, protective conduit.；At this point, floating ball 2 is due under suction
It falls, floating ball 2 can quickly bump against with 1 pallet 16 of valve body.When floating ball falls, cushion pad can play the role of buffering, avoid floating
Ball directly bumps against with pallet 16, damages floating ball.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
