Description
[technical field]
The utility model relates to a kind of outlet valve, relates in particular to the outlet valve of installing on a kind of water supply line, is specifically related to a kind of outlet valve with leak-proof protection device.
[background technique]
At present, the city mostly is single port formula or composite exhaust valve greatly for the outlet valve that uses on/the drainage pipe, shown in People's Republic of China's utility model patent the 200820119018.3rd, it has promptly disclosed a kind of composite exhaust valve, it comprises: a valve body, be positioned at the floating drum of valve body, but be positioned at the valve gap of valve body upper end and the guide rod of oscilaltion, this guide rod is connected on the floating drum, the top offers an opening in valve body in floating drum, be used to discharge the gas in confession/drainage pipe, be provided with an air flap in the end of guide rod.When the water in the pipeline holds up floating drum, the opening of the valve body sealed is prevented that sewage from reserving in outlet valve thereby guide rod drives air flap.
Yet this type of outlet valve mainly contains following shortcoming in day-to-day operation:
1, seepage and do not have any leakage protection device takes place
Sewage outlet valve generation main cause of seepage is that the sewage collecting amount is inhomogeneous, and pipeline start-stop pumping frequency is numerous, causes manifold pressure to change greatly, and it is less than normal in the situation of outlet valve normal operating pressure manifold pressure often to occur.Contain a large amount of impurity rubbish in addition in the sewage, cause valve inner driver and seal element stuck easily.Because outlet valve generally is installed on the bridge tube of crossing over the river, in case ooze dew, may cause the serious environmental contamination accident.
2, the back alarm free device that breaks down
After outlet valve generation seepage, lack automatic warning function.Because the outlet valve mounting point is generally the bridge tube top, and manifold pressure and the basic no change of flow after the seepage take place, the operation management personnel are difficult to timely discovery.
For solving the problems of the technologies described above, the necessary outlet valve that a kind of more advanced band leak-proof protection device is provided is to overcome described defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of this utility model is to provide a kind of outlet valve that can effectively prevent the band leak-proof protection device that sewage leaks and can in time report to the police.
For achieving the above object; the technological scheme that the utility model is taked is: a kind of outlet valve with leak-proof protection device; it comprises valve body, valve gap, guide rod and ball float; wherein; described valve gap is installed on the upper end of valve body, and described guide rod is positioned at valve body and energy oscilaltion, and described ball float is connected to the bottom of guide rod; described valve gap further is provided with a taper exhaust port with certain altitude, and a taper rubber stopper that matches with the taper exhaust port is installed on the body of rod.
The outlet valve of band leak-proof protection device of the present utility model further is set to: described taper exhaust port is identical with the tapering of taper rubber stopper.
The outlet valve of band leak-proof protection device of the present utility model further is set to: described valve gap bottom is equipped with a position shelf, and this position shelf comprises one first positioning hole and a upper surface, and described taper rubber stopper bottom surface can contact the upper surface of position shelf.
The outlet valve of band leak-proof protection device of the present utility model further is set to: be provided with a positioning plate in described taper exhaust port top; be provided with second positioning hole of aiming at first positioning hole in described positioning plate, described guide rod passes described first positioning hole and second positioning hole.
The outlet valve of band leak-proof protection device of the present utility model further is set to: described taper rubber stopper adopts interference fit to be installed on the guide rod.
The outlet valve of band leak-proof protection device of the present utility model further is set to: place, described valve body lower middle is provided with one the probe mounting hole of alarm probe is installed.
The outlet valve of band leak-proof protection device of the present utility model also can be set to: the bottom of described valve body is provided with a base flange that is used for this outlet valve of fixing.
Compared with prior art, the utlity model has following beneficial effect:
(1) good leak tightness is stopped seepage.
Air locking is conical rubber stopper, adopt the cone match air-tight manner, area of contact is big, after effluent seepage enters the sealing device, and the ball float come-up, conical rubber stopper jam-pack taper exhaust port under buoyancy function, many more when entering sewage, buoyancy is big more, and rubber stopper is filled in tighter and tighter, so that effluent seepage is stopped in sealing fully.
(2) in time report to the police timing monitoring.
Valve body is provided with an onsite alarming device with alarm probe, the action in a single day of obturator part, and warning device will send alarm signal, remind operation management in time outlet valve to be overhauled.
