Abstract
The utility model discloses a leakage prevention exhaust valve, which comprises the following components: a valve body, the valve body middle part is provided with the air receiver, fixedly connected with flotation pontoon on the valve body, and the flotation pontoon link up with the air receiver mutually, the floater is installed to the lower part of flotation pontoon, the fixed upper cover that is provided with in flotation pontoon upper portion, the upper portion fixedly connected with connecting rod of floater, the center department of upper cover is provided with and supplies connecting rod male through -hole, the inside limiting plate that is used for blockking the floater that still is provided with of flotation pontoon, the limiting plate is hollow out construction, the inside uide bushing that supplies the connecting rod to pass that still is provided with of flotation pontoon, be provided with matched with sealing device between the upper end of connecting rod and the through -hole of upper cover. Be provided with double gas vent, a gas vent setting is between valve body and flotation pontoon, through the switching of controlling of floater, another gas vent installs sealing device additional on the connecting rod with the floater linkage, adopt the discharge valve that avoids that double gas vent can be better to appear leaking.
Description
Technical field:
This utility model belongs to valve technology field, especially relates to a kind of leakage prevention exhaust valve.
Background technology:
Because generally all dissolved with certain air in water, and the dissolubility of air reduces along with the rising of temperature, such water gas in the process of pipeline internal recycle is separated gradually from water, and the bubble even gas column that formation of getting together gradually is big, because having supplementing of water, so often there being gas to produce.When there is substantial amounts of bubble in pipeline, the current in pipeline there will be the phenomenon of insufficient pressure in the process of circulation, also can produce bigger noise simultaneously, and the air of the therefore existence in pipe needs to get rid of in time.If one sealing air vent of current tube exhaust valve, it is impossible to well solve pipe leakage problem.
Summary of the invention:
Technical problem to be solved in the utility model is: provides and adopts two seals air vent, it is to avoid valve leaks when aerofluxus.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: a kind of leakage prevention exhaust valve, including valve body, it is provided with air storage chamber in the middle part of described valve body, described valve body is fixedly connected with floating drum, and described floating drum connects with air storage chamber, the bottom of described floating drum is provided with ball float, described floating drum top is fixedly installed upper cover, and the top of described ball float is fixedly connected with connecting rod, and the center of described upper cover is provided for the through hole that connecting rod inserts.
As preferably, being additionally provided with the limiting plate for stopping ball float inside described floating drum, described limiting plate is engraved structure.
As preferably, being additionally provided with the fairlead for connecting rod traverse inside described floating drum, described fairlead offers passage.
As preferably, being provided with, between upper end and the through hole of upper cover of described connecting rod, the sealing device matched.
Compared with prior art, of the present utility model having the beneficial effect that is provided with double air vent, and an air vent is arranged between valve body and floating drum, controls opening and closing by ball float；Another air vent with the connecting rod of float link on install sealing device additional；Double air vent is adopted can better to avoid air bleeding valve that leakage occurs.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, this utility model is further illustrated.

Fig. 2 is exhaust condition schematic diagram of the present utility model.
In figure: 1, valve body；11, air storage chamber；2, floating drum；3, ball float；4, upper cover；41, through hole；5, connecting rod；6, limiting plate；7, fairlead.
Detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, this utility model is described in detail:
A kind of leakage prevention exhaust valve as depicted in figs. 1 and 2, including valve body 1, it is provided with air storage chamber 11 in the middle part of described valve body 1, described valve body 1 is fixedly connected with floating drum 2, and described floating drum 2 connects with air storage chamber 11, and the bottom of described floating drum 2 is provided with ball float 3, and described floating drum 2 top is fixedly installed upper cover 4, the top of described ball float 3 is fixedly connected with connecting rod 5, and the center of described upper cover 4 is provided for the through hole 41 that connecting rod 5 inserts.
Upwards floating in order to avoid ball float 3 is excessive, described floating drum 2 is internal is additionally provided with the limiting plate 6 for stopping ball float 3, and described limiting plate 6 is engraved structure.
In order to avoid skew occurs when moving up and down in connecting rod 5, described floating drum 2 is internal is additionally provided with the fairlead 7 for connecting rod 5 traverse, and described fairlead 7 offers passage.
It is provided with, between upper end and the through hole 41 of upper cover 4 of described connecting rod 5, the sealing device matched, adopts this structure to increase the sealing that valve is overall.
It is emphasized that: be only preferred embodiment of the present utility model above, not this utility model is done any pro forma restriction, every any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still falls within the scope of technical solutions of the utility model.
