Description
Technical field
The utility model is a kind of degassing valve that removes contained gas in heat supply or the refrigeration system circulating water, particularly a kind of spiral degassing valve that removes free gas, micro gas-bubble and dissolved gas in the circulating water.This degassing valve makes circulating water remain very strong absorbing state, fundamentally solves the noise problem that circulatory system internal cause air causes.
Background technique
There is gas in the systemic circulation water, can causes the generation of a lot of noises, as the noise of water pump and pipeline generation, the underwater sound that flows through as waterfall in the radiator.What face came thereupon is corrosive pipeline, and device efficiency reduces, and indoor heating and refrigeration are not enough, and equipment attrition is quickened.In order to remove gas contained in the systemic circulation water, so the degassing valve of degassing function occurred having, existing bleed valve can produce good degasification to the bubble that volume is bigger in the systemic circulation water, but just powerless for micro gas-bubble and dissolved gas.
Summary of the invention
The purpose of this utility model is in order to overcome existing bleed valve for micro gas-bubble in the circulating water and the helpless defective of dissolved gas, invent and a kind ofly can in bleed valve, produce a relative stagnant zone, the gas that all size bubbles in the circulating water is comprised be dissolved in the water can both be at this spiral that is separated degassing valve, thereby the maintenance system is in no gaseity all the time, guarantee that system can not produce any noise, guarantee that system pipeline is not corroded, improve equipment operating efficiency.
The purpose of this utility model realizes as follows: described spiral degassing valve, comprise a shell, the bottom of shell is provided with bottom, bottom is provided with blowdown valve, the both sides of shell lower end are respectively equipped with water intake and drain opening, one side of shell upper end is provided with outlet valve (the above degassing of DN50 valve), and the top of shell is provided with top cover, is provided with automatic atmospheric valve above the top cover; The inside of shell is provided with upper backup pad and lower supporting plate, upper backup pad be fixed in top cover below, between upper backup pad and the automatic atmospheric valve is air chamber, lower supporting plate is fixed in the lower end of shell, be provided with single between upper backup pad and the lower supporting plate or many volutes, volute filters silk screen by central shaft tube and cylindrical screw and forms; It is the cylinder solid multi-layer helical basket shape structure that is formed by metal wire bond system that cylindrical screw filters silk screen, and cylindrical screw filters the inner wall sleeve of silk screen on central shaft tube, and is welded on the center sleeve outer surface.
Be provided with hanger above the described top cover.
Described central shaft tube is copper tubing.
It is copper wire that described cylindrical screw filters the used wire of silk screen.
Good effect of the present utility model is as follows: the plane structure that the cylindrical screw filter screen changes traditional filter screen is three-dimensional cylinder cross network structure, compare with the plane filter screen, it has increased the work area of filtering greatly, dispersing fluid effectively, gas in the water is effectively disengaged, strengthened degassing ability.Volute is that a kind of filtration work area is big, has the cylindrical screw filter screen of good degasifying effect.The cylindrical screw filter screen, owing to be provided with volute, such structure can make fluid produce a relative stagnant zone in degasser, the while has effectively been disperseed liquid, makes that gas is easier to be disengaged, even the most small bubble also has the enough time to separate from fluid.The gas of separating collects in the air chamber, and by valve air relief emptying, the outlet valve of valve body side can be removed suspended impurity; The utility model can shorten in the system starting time after the first water filling greatly, and need not emptying, makes system keep best hot transmit mode, prolongs service life of equipment, makes system not have oxygen corrosion or pump cavitation phenomenon; Noise free when the utility model can be guaranteed system's operation.

Embodiment
As shown in Figure 1, described spiral degassing valve, comprise a shell 1, the bottom of shell 1 is provided with bottom 2, bottom 2 is provided with blowdown valve 3, and the both sides of shell 1 lower end are respectively equipped with water intake 4 and drain opening 5, and a side of shell 1 upper end is provided with outlet valve 6, the top of shell 1 is provided with top cover 7, is provided with automatic atmospheric valve 8 above the top cover 7; The inside of shell 1 is provided with upper backup pad 9 and lower supporting plate 10, upper backup pad 9 be fixed in top cover 7 below, between upper backup pad 9 and the automatic atmospheric valve 8 is air chamber 11, lower supporting plate 10 is fixed in the lower end of shell 1, constitute a space 12 between lower supporting plate 10 and the bottom 2, be provided with single between upper backup pad 9 and the lower supporting plate 10 or many volutes, volute filters silk screen 14 by central shaft tube 13 and cylindrical screw and forms, it is the cylinder solid multi-layer helical basket shape structure (see figure 2)s that formed by metal wire bond system that cylindrical screw filters silk screen 14, cylindrical screw filters the inner wall sleeve of silk screen 14 on central shaft tube 13, and is welded on the outer surface of center sleeve 13.
Be provided with hanger 15 above the described top cover 7.
Described central shaft tube is copper tubing.
It is copper wire that described cylindrical screw filters the used wire of silk screen.
During use, this spiral degassing valve must be installed on the main line, and is preferably temperature peak in the system.For heating system, the optimum position is the outlet line of boiler, and top, spiral degassing valve mounting point static pressure can not surpass 15m; For refrigeration system, the temperature peak is on the return piping of cooler, and top, spiral degassing valve mounting point static pressure can not surpass 5m.Temperature is high more, the easy more release of micro gas-bubble in the water, the process of gas release is according to the Henry law principle: solubility and the temperature of gas in water is inversely proportional to, be directly proportional with pressure, when temperature increase or pressure reduction, because reducing of solubility, dissolved gases can discharge again in the water.Spiral degassing valve utilizes this characteristic cleverly, continues the degassing in the systemic circulation process.
