Description
Technical field
This utility model relates to valve technology field, particularly relates to a kind of novel combined air bleeding valve.
Background technology
Air bleeding valve is mostly installed at for the gas having arranged in pipeline at the high point of aqueduct, when there being gas on waterline
When body overflows, gas can be climb along pipeline and be entered air bleeding valve valve pocket and be gathered in the top of air bleeding valve, along with gas in valve
Increasing, pressure rises, and when gas pressure is more than system pressure, gas can make the intracavity water surface decline, and float removes with water level one
Fall, opens air vent；After gas drains, water level rises, and movable block rises the most therewith, closes air vent.Same reason, when being
Producing negative pressure in system, in valve pocket, the water surface declines, Exhaust Open, owing to now external atmosphere pressure force rate system pressure is big, so
Air can enter system by air vent, prevents the harm of negative pressure.Existing novel combined air bleeding valve, produces during water delivery
Gas, be required for discharging from this outlet, and be not required to a large amount of aerofluxus when hydraulic pipeline normally carries, only have a small amount of empty
Gas is gathered in valve, and the most novel combined air bleeding valve still can be exhausted, and causes stainless steel floating ball to make lifting row frequently
Pneumatic work, thus reduce the service life of stainless steel floating ball.And the flange seal in existing novel combined air bleeding valve exists
Air-tightness problem.
Based on above reason, a kind of novel combined air bleeding valve is needed to be devised, by being provided with charge valve
Sacculus, can by regulating the buoyancy size of sacculus, regulate the size of motion and exhaust outlet number, sensitivity carries
High；By arranging upper end cover, when need not aerofluxus, it is possible to prevent negative pressure；By arranging the sealing draw-in groove on ring flange, it is ensured that
Sealing between ring flange, a kind of novel combined air bleeding valve.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of novel combined air bleeding valve.
This utility model is to be achieved through the following technical solutions: a kind of novel combined air bleeding valve, including valve body, and described valve
Body lower end connects has ring flange, described ring flange bottom to be provided with sealing draw-in groove；Described valve inner is provided with air bag, described air bag
On be provided with charge valve, described air bag is connected to the right-hand member of lever, and described lever is connected by the rotating shaft of clamping fixing bar,
The upper end of described fixing bar is fixed in the upper wall of valve body, and the left end of described lever is hinged with pull bar, the upper end hinge of described pull bar
Being connected on the lower end of movable post, described movable column sleeve is connected in aiutage, and described aiutage is arranged on the upper wall left end of valve body, described
Aiutage upper end is provided with upper end cover by hinge, described aiutage sidewall is provided with pore, in the lower end of described aiutage
Being provided with sealing gasket on wall, the lower end of described aiutage is provided with through hole, and described pull bar is moved by through hole.
Further, described pore is I shape, beneficially aerofluxus.
Further, described ring flange is fixed on the lower end of valve body by welding manner.
Further, the bottom activity of described movable post is real fits on sealing gasket, it is ensured that sealing function.
Further, described sealing draw-in groove and ring flange integrated molding, it is ensured that the sealing between ring flange.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design,
By being provided with the sacculus of charge valve, size and the aerofluxus of motion can be regulated by regulating the buoyancy size of sacculus
Draining number, sensitivity improve；By arranging upper end cover, when need not aerofluxus, it is possible to prevent negative pressure；By arranging flange
Sealing draw-in groove on dish, it is ensured that the sealing between ring flange.
