Abstract
The utility model relates to the special outlet valve of a kind of solar energy, it is characterized in that: the bridge piece that comprises middle part bending, valve body is connected to the end of bridge piece, in the valve pocket of valve body, be provided with sideboard, the chamber wall of the end of sideboard and valve pocket is hinged, be embedded in Sealing shield ring at valve body, on valve body, be provided with outlet pipe, outlet pipe is connected with valve body via Sealing shield ring, under normal circumstances, sideboard naturally droops and is separated with Sealing shield ring under self gravitation effect, in other cases, sideboard is close to Sealing shield ring, block outlet pipe by sideboard.The utility model, owing to adopting outlet pipe and valve body all can have larger bore and valve pocket internal path, is extremely conducive to the discharge of a large amount of water vapour, and to the safety of system, normal operation provides guarantee.
Description
Technical field
The utility model relates to the special outlet valve of a kind of solar energy, for the discharge of steam in solar water-heating system solar thermal collector.
Background technique
The automatic control pressure vent in the past using in solar water-heating system has copper, stainless steel, rough structure mainly contains several most of compositions of valve body, valve rod, floating drum and dust cap, its working principle is: outlet valve is arranged on system peak, when in system when gas overflowing, gas can be climb along pipeline, finally collects in system peak.Gas enters outlet valve valve pocket, is gathered in the top of outlet valve, along with increasing of gas in valve, and pressure rise, in the time that gas pressure is greater than system pressure, gas can make the water surface in chamber decline, and floating drum declines with water level, opens relief opening and carries out exhaust; After gas drains, water level rises, and floating drum, also along with rising, is closed relief opening.
In like manner, when producing in system after negative pressure, in valve pocket, the water surface declines, Exhaust Open, and now ambient pressure is larger than system pressure, and atmosphere can enter system by relief opening, prevents the harm of negative pressure.
In conjunction with structure and the working principle of outlet valve in the past, can find out that floating drum plays critical effect.But the relief opening on the exhaust port on floating drum and valve body is all smaller.But solar thermal collector in solar water-heating system generally combines by much organizing series parallel connection, in the vacuum tube in heat collector, store for a long time a large amount of water, under the irradiation of sufficient sunlight, can produce a large amount of heats, and then generate a large amount of water vapour.Relief opening on exhaust port and valve body on floating drum is less, is unfavorable for the discharge of water vapour, and a large amount of water vapour is present in solar thermal collector, can cause very large harm to total system.
Summary of the invention
The purpose of this utility model is to provide a kind of outlet valve for solar water-heating system that can discharge more water vapour.
In order to achieve the above object, the technical solution of the utility model has been to provide the special outlet valve of a kind of solar energy, it is characterized in that: the bridge piece that comprises middle part bending, valve body is connected to the end of bridge piece, in the valve pocket of valve body, be provided with sideboard, the chamber wall of the end of sideboard and valve pocket is hinged, be embedded in Sealing shield ring at valve body, on valve body, be provided with outlet pipe, outlet pipe is connected with valve body via Sealing shield ring, under normal circumstances, sideboard naturally droops and is separated with Sealing shield ring under self gravitation effect, in other cases, sideboard is close to Sealing shield ring, block outlet pipe by sideboard.
The utility model, owing to adopting outlet pipe and valve body all can have larger bore and valve pocket internal path, is extremely conducive to the discharge of a large amount of water vapour, and to the safety of system, normal operation provides guarantee.
Brief description of the drawings
The structural representation of the special outlet valve of a kind of solar energy that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The special outlet valve of a kind of solar energy of the utility model comprises the bridge piece 6 of middle part bending, valve body 5 is connected to the end of bridge piece 6, in the valve pocket of valve body 5, be provided with sideboard 3, the chamber wall of the end of sideboard 3 and valve pocket is hinged, in the present embodiment, on the wall of the chamber of valve pocket, output position, a hole, the end of sideboard 3 can be fixed on this Kong Weizhong by wire, thereby realizes hinged.Be embedded in Sealing shield ring 2 at valve body 5, be provided with outlet pipe 1 on valve body 5, outlet pipe 1 is connected with valve body 5 via Sealing shield ring 2.
Under normal circumstances, the axis of part, valve body 5 and the outlet pipe 1 of bridge piece 6 and horizontal line are the angle of α=30 degree, now, sideboard 3 naturally droops and is separated with Sealing shield ring 2 under self gravitation effect, the valve pocket of valve body 5 is directly communicated with the atmosphere of outside, in the time having water vapour to generate in system, water vapour can be discharged from outlet pipe 1 immediately.In other cases, sideboard 3 is close to Sealing shield ring 2, blocks outlet pipe 1 by sideboard 3.
