Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of valve, particularly a kind of outlet valve.
Background technique
Outlet valve is applied to pipeline exhausts such as independent heating system, central heating system, heating boiler, central air-conditioner, floor heating and solar heating system.Because all be dissolved with certain air in the water usually; And the solubility of air reduces along with the rising of temperature, and water gas in the circuit process is separated from water gradually like this, and gets together gradually and form big bubble even gas column; Because replenishing of water arranged, so often there is gas to produce.
When having gas to overflow in the system, gas can be climb along pipeline, finally accumulates in the peak of system; And outlet valve generally all is installed in system's peak, when gas gets into the top that the outlet valve valve pocket accumulates in outlet valve, along with increasing of gas in the valve; Pressure rises, and when gas pressure during greater than system pressure, gas can make the water surface decline chamber in; Floating drum descends with water level, opens relief opening; After gas drained, water level rose, and floating drum also rises thereupon, closes relief opening.Same reason produces negative pressure in system, the water surface descends in the valve pocket, and Exhaust Open because this moment, external atmosphere pressure force rate system pressure was big, so atmosphere can get into system through relief opening, prevents the harm of negative pressure.As tighten the bonnet on the outlet valve valve body, and outlet valve stops exhaust, and generally, bonnet should be in opening state.Outlet valve also can be followed the supporting use of isolating valve, is convenient to the maintenance of outlet valve.
A kind of automatic control pressure vent [the application number: 00213196X that openly proposes like the Chinese patent documents and materials; Notice of authorization number: CN2410485Y], be provided with float in its valve body, valve gap is provided with exhaust valve, is provided with exhaust plug in the exhaust valve; The exhaust valve below is provided with support, hinged depression bar one end in support below, and depression bar is connected with exhaust plug, and the depression bar the other end and float are hinged; The valve body below is provided with the connection valve body, is provided with the connection spool in it, connects spool and is provided with spring, and the top is provided with disk; The center is provided with the water inlet, unloads valve body during maintenance, connects spool under the effect of spring; With the water inlet sealing, easy to maintenance, be applicable to heating system.But because this automatic control pressure vent adopts the restoring force effect of spring to make exhaust plug with the relief opening shutoff, so after using the long period, spring loses generation deformation, makes sealing effect relatively poor.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, proposed a kind of sealing effect better, the life-span is long and the comparatively simple outlet valve of structure.
The purpose of the utility model can realize through following technical proposal: a kind of outlet valve; Comprise the inner valve body of cavity that is; Said two ends of valve body is respectively and is used for interface end that links with pipeline and the exhaust end that communicates with the external world, it is characterized in that, is provided with the floating block that can move up and down along valve body in the described valve body; Has the relief opening that supplies air to pass through between said floating block and the valve body; Said floating block is provided with Sealing, is provided with elastic component between described floating block and the valve body, has the trend with the relief opening shutoff in the elastic force effect lower seal of elastic component.
This outlet valve is installed in the peak of pipeline through interface end, and when in the pipeline air being arranged, air enters into the top of the cavity of valve body along interface end; The air of cavity internal upper part presses down the liquid in the pipeline, and liquid is descended, and the decline of liquid and then descends the floating block that is arranged in the valve body; The decline of floating block drives Sealing and descends, and relief opening is performed fighting, and air is got rid of from relief opening; At this moment, the pressure in the cavity descends, and the liquid in the cavity rises; Under the effect of floating block buoyancy and elastic component elastic force, make and move on the Sealing and the relief opening shutoff.
In above-mentioned outlet valve, described elastic component is a rubber-like connecting rod one, and an end of connecting rod one is connected on the valve body, and the other end of connecting rod one is connected on the floating block.Air in cavity presses down liquid, when floating block is sunk, drives the drop-down disengagement of seal member relief opening that makes of Sealing through connecting rod one, and the air in the cavity is discharged from relief opening; This moment, the pressure in the cavity descended, and liquid rises in cavity, under the effect of floating block buoyancy and connecting rod elastic force, moved on the Sealing and with the relief opening shutoff.
In above-mentioned outlet valve, the quantity of said connecting rod one is two, and the both sides that are arranged at floating block of two connecting rod one symmetries.Two connecting rod one symmetries are arranged on the both sides of floating block, make floating block when mobile, and both sides receive equal power, have guide function preferably.
As other a kind of scheme, in above-mentioned outlet valve, described elastic component is a spring, and the two ends of spring are connected on valve body and the floating block.The restoring force of spring has the trend that moves up to floating block, and after the air in the cavity had been arranged, the effect of the restoring force through buoyancy of liquid and spring made to move on the floating block to make Sealing with the relief opening shutoff.
In above-mentioned outlet valve, said Sealing adopts nylon material to process, and is connected through rubber-like connecting rod two between described Sealing and the floating block.Connecting rod two links to each other Sealing with floating block, make floating block can drive Sealing with relief opening shutoff or open moving up and down to make, and in relief opening shutoff or the process opened, because connecting rod two has elasticity, so connecting rod two also has buffer function.
In above-mentioned outlet valve, the quantity of said connecting rod two is two, and two disymmetrical both sides that are arranged at Sealing of connecting rod.Two connecting rods two can make Sealing in shutoff or when opening relief opening, and are comparatively stable, and Sealing can be accurately with the relief opening shutoff, and also have cushioning effect preferably.
In above-mentioned outlet valve, have the joint that protrudes from the valve body inboard on the described relief opening, have the sealed department that is complementary with joint on the above-mentioned Sealing.Joint that protrudes on the relief opening and the sealed department on the Sealing are complementary, and Sealing has plugging effect preferably.
Compared with prior art, this outlet valve has the following advantages:
1, through under the elastic reaction and floating block buoyancy function that connecting rod one and connecting rod two are set, Sealing is perhaps opened the relief opening shutoff, have sealing effect advantage preferably;
2, also to have structure comparatively simple for this outlet valve, the advantage that working life is long.
