Description
Technical field
This utility model relates to valve technology field, particularly relates to a kind of composite exhaust 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 composite exhaust valve, the gas produced during water delivery
Body, is required for discharging from this outlet, and is not required to a large amount of aerofluxus when hydraulic pipeline normally carries, and the most a small amount of air gathers
Collection is in valve, and now composite exhaust valve still can be exhausted, and causes stainless steel floating ball to make frequently to lift exhaust event, from
And reduce the service life of stainless steel floating ball.
Based on above reason, a kind of novel combined air bleeding valve is needed to be devised, T-shaped by arrange on movable post
Pore, plays the effect of buffering to aerofluxus and draining；By arranging the bolt fastening port of sidewall, the sealing surface of flange is changed
Enter, increase seal washer, improve sealing property；By arranging sealing gasket, improve the seal of cylinder, i.e. a kind of combined type
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 composite exhaust valve.
This utility model is to be achieved through the following technical solutions: a kind of composite exhaust valve, including valve body, under described valve body
End connection has flange-interface, described flange-interface sidewall to be provided with bolt fastening port, and described flange-interface bottom is provided with sealing
Packing ring；Described valve inner is provided with stainless steel floating ball, and described stainless steel floating ball is connected to the right-hand member of lever, and described its intermediate part cuts with scissors
Being connected to 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, described in draw
The upper end thereof of bar, in the lower end of movable post, described movable post is provided with pore, and described movable column sleeve is connected in cylinder, described
Cylinder is fixed on the upper wall left end at valve body, and described cylinder upper end is provided with upper cover, the lower end of described cylinder by hinge
Being provided with sealing gasket on inwall, the lower end of described cylinder is provided with through hole, and described pull bar is moved by through hole.
Further, the upper end of described movable post is provided with flange, the real top fitting over sealing gasket of described flange, it is ensured that
The seal of cylinder.
Further, described pore is inverted T shape structure, and aerofluxus and draining are played the effect of buffering.
Further, described seal washer is that rubber gasket, airtight performance and damping performance are good.
Further, described flange-interface is fixed on the lower end of valve body by welding manner.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design,
By arranging the T-shaped pore on movable post, aerofluxus and draining are played the effect of buffering；Fasten by arranging the bolt of sidewall
Mouthful, the sealing surface of flange is improved, increases seal washer, improve sealing property；By arranging sealing gasket, improve gas
The seal of cylinder.
