Abstract
The utility model relates to an air-water separator for a central heating system, which belongs to air-water separators. The utility model is characterized in that the outer wall of a float is uniformly distributed with axial positioning blocks which are used for centering the float and connected with a casing body of the air-water separator in a sliding way, and each positioning block has the thickness of 3-6 mm. The top of the float is provided with a baffle plate which has the diameter more than the diameter of the float, and an interval is arranged between the plate and the top of the float. The axial positioning blocks center the float as well as simultaneously reduce the range of radial movement of the float, and thus, the float and the wall of a casing body of the air-water separator can keep reasonable distance. Therefore, the utility model can effectively avoid the air in the water gathering into big air bubbles, and meanwhile, the utility model can smash the bigger air bubbles formed in the water. As a consequence, the utility model avoids air flow with stronger pressure formed during continuous rupture of the big air bubbles. A water baffling ring inside a end cover can effectively block the circulating water carried by the rising air flow so as to avoid the circulating water being ejected along with the rising air flow. In a word, the utility model has the prominent advantages of reasonable structure, reliable effect of air-water separation and air exhaust and water ejection victory.
Description
Technical field
The utility model belongs to moisture trap, especially relates to the moisture trap in a kind of heating system.
Background technology
A kind of moisture trap that is used for the hot water circuit heating system of external introduction is made of the tube connector of housing, housing bottom, the end cap of band blast pipe and the float in the housing, and its end cap inboard is provided with the switchboard that is articulated by " U " type spring.High water level in the housing will make the seal gasket of switchboard engage with the endoporus of blast pipe, and when the gas increase in the housing descended water level, the free sagging gas of switchboard was discharged when float descended thereupon.Owing to remain actual conditions more at entrained gas and that water quality is relatively poor in the present domestic hot water circuit heating system, therefore following problem in use generally appears in above-mentioned moisture trap, i.e. also ejection thereupon of recirculated water in the time of exhaust.Reason is that float and housing wall spacing are excessive, reach more than the 6mm, make float be in radially free state, the local spacing of float and housing wall also is a labile state, local spacing larger part makes in the water gas compile to be air pocket, and the air-flow that formed pressure is stronger when the continuous explosion of air pocket must carry moisture and spray together.
Summary of the invention
The also technical problem of ejection thereupon of recirculated water when the utility model is the exhaust that in use generally occurs for the moisture trap that solves above-mentioned introduction, and moisture trap in a kind of gas-water separation heating system reliable for effect is proposed.
The utility model is taked following technical scheme for the technical problem that the moisture trap that solves above-mentioned introduction exists: the float outer wall is uniform to make it axial location piece centering, that be slidably engaged with the moisture trap housing, the thickness of this locating piece is 3-6mm, the float top is provided with the barrier plate of diameter greater than float, this plate be provided with at interval with the float top.
The utility model is also taked following technical measures:
The end cap of described moisture trap, its inboard are provided with the switchboard that is supported by axle bed and axle, and an end of switchboard engages with the hole slot of float fulcrum pin setting.
The end cap of described moisture trap, its inboard is provided with retaining ring.
The beneficial effects of the utility model and advantage are: also make it move radially scope when the axial location piece makes float centering and reduce, float is kept and the rational spacing of moisture trap housing wall, therefore can effectively avoid in the water gas to compile and be air pocket, also can smash simultaneously in water, formed than air pocket, thereby the stronger air-flow of formed pressure when having avoided the continuous explosion of air pocket.Barrier plate that the float top is provided with and float top have the depression that forms by at interval, and this depression plays the effect that smashes bubble equally.Can also effectively stop the working medium of unexpected ascension simultaneously and help smashing rising bubble.The retaining ring of end cap inboard can stop effectively that the moisture that ascending air carries avoids it to spray thereupon, and makes and continue the bubbles strike retaining ring that rises and be crashed to pieces, and avoids moisture to spray with it.In a word, the utlity model has rational in infrastructure, gas-water separation is reliable for effect, can thoroughly overcome the outstanding advantage that exhaust is sprayed water simultaneously.
Description of drawings
Accompanying drawing 1 example structure schematic diagram.
Drawing reference numeral: 1 housing, 2 floats, 3 locating pieces, 4 barrier plates, 5 float fulcrum pins, 6 end caps, 7 retaining rings, 8 switchboards, 9 blast pipes, 10 axle beds.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in the figure, float 2 and moisture trap housing 1 inwall are provided with the spacing of 4mm, and it is to be realized by the thickness of uniform 4 the axial locating pieces 3 of float outer wall, and each locating piece makes float 2 centerings and is slidably engaged with the moisture trap housing.The top of float 2 is provided with the barrier plate 4 of diameter greater than float, this plate with 3mm is set at interval with the float top.
End cap 6 inboards of moisture trap are provided with the switchboard 8 that is supported by axle bed 10 and axle, one end of switchboard engages with the hole slot that float fulcrum pin 5 is provided with, and hole slot makes switchboard hightail the inner port of blast pipe 9 the Drawing switch plate and opens when float drops to certain position.End cap 6 inboards also are provided with retaining ring 7, have moisture to be taken out of when further preventing the exhaust of this separator.
Claims (3)
1, the moisture trap in the circulating water heating system, formed by housing, end cap and blast pipe, float and switchboard, it is characterized in that: the float outer wall is uniform to make it axial location piece centering, that be slidably engaged with the moisture trap housing, the thickness of this locating piece is 3-6mm, the float top is provided with the barrier plate of diameter greater than float, this plate be provided with at interval with the float top.
2, moisture trap according to claim 1 is characterized in that: the end cap of described moisture trap, its inboard are provided with the switchboard that is supported by axle bed and axle, and an end of switchboard engages with the hole slot of float fulcrum pin setting.
