Abstract
The utility model relates to an automatic exhausting valve for hot water heating, which adopts a float and lever structure. The utility model is characterized in that a lever is designed with a cushioning torsion spring, the lever is directly provided with a sealing gasket corresponding to an exhausting valve, a float is provided with a through hole, and the inner cavity of the float can be formed with an air chamber and can not accumulate water to cause that the float losses the effect. The integral structure is light, the opening and closing reaction is sensitive, and the work is reliable. The utility model is suitable for exhausting the accumulated air of all the hot water heating heat supply and the heat exchange pipeline systems, and the transmission and the transformation of the heat efficiency of the system is efficiently improved.
Description
The utility model valve kind technology is specifically related to a kind of outlet valve of automatic eliminating air accumulation of hot-water heating heating system.
Hot-water heating automatic control pressure vent at known employing lever construction, for example in the disclosed class technological scheme of CN87217539U and CN2086826U, the lever that connects float relies on bearing pin hinge joint location merely, its opening/shutting valve action and valve seal pressure are realized by the buoyancy of float fully, like this under the certain situation of the transition of air water mixed pressure and moulding float buoyancy, the big or small bad further coordination of the sensitivity of valve opening and closing and sealing load causes overflowing of mixed flow gas-liquid easily.Secondly, this type of technology has all adopted parts such as guide pillar, push rod as the motion spool, still dislikes clumsy from structure, has increased valve opening and closing moment simultaneously, has further influenced the keying sensitivity of valve.
Order of the present utility model is to provide a kind of valve opening and closing highly sensitive, and better coordinates with sealing load, and the organization plan of the more light and handy hot-water heating automatic control pressure vent of structure.
Scheme of the present utility model is such,
Wishbone lever (4) one ends and float (2) link, one end links by bearing pin (7) and the retainer hinge joint that is fixed on the valve gap (14), the exhaust port (17) of the corresponding exhaust nozzle of wishbone lever (12) is provided with sealing gasket (19), it is long-armed that both feet torsion spring (5) one ends act on wishbone lever, and an end is set on the bearing pin (7).The lifting of float relies on buoyancy on the one hand, is subjected to the effect of torsion spring spring power on the one hand, makes its operating stably and reliable sealing.For avoiding anhydrous for a long time in valve body, it is stressed to influence the long-term stretching of torsion spring when float is sagging, and connecting ear (6) design at wishbone lever galianconism one end has boss (8), and boss cooperates with retainer is spacing, make the wishbone lever subtended angle unlikely excessive, alleviate the spring stress distortion.
The lower end of float (2) has through hole, and when water level rose, the float epicoele was subjected to water seal to form air cavity, generates float buoyancy, and during drawdown, a small amount of ponding in the float can release by via through holes again.
The exhaust end of exhaust nozzle (12) is provided with to fall and spatters helmet (11).
The utlity model has tangible advantage, the keying of valve is more sensitive, and it is more reliable to work, and overall structure is more light and handy, has better practicability.
Below in conjunction with accompanying drawing the utility model is made into specific descriptions.
Accompanying drawing 1 is a hot-water heating automatic control pressure vent sectional view.
Accompanying drawing 2 is wishbone lever torsion spring assembling schematic representation.
Exhaust nozzle (12) is anchored on valve gap (14) by rubber cushion (13), hexagon nut (9), and an end is fixed with the splashproof helmet (11) of can transposing by nut or fastening piece, when not needing exhaust, helmet can be screwed, and helmet the inner is provided with sealing gasket (10).The exhaust port of the other end of exhaust nozzle (17) is corresponding with the rubber cushion (19) on the wishbone lever (4).Wishbone lever one end links with retainer on being fixed on valve gap by bearing pin (7) mutually to connect ear, and with the spacing rotation of boss (8); The other end links by fixed block (3) and float.Wishbone lever also produces twisting moment with torsion spring (5) and bearing pin (7).The float lower end has through hole (18).Valve gap is by fastening piece (15), sealing gasket (16) and valve body (1) fit sealing, and valve body (1) lower end or sidepiece (horizontal) have admission line.
Claims (4)
1, a kind of hot-water heating automatic control pressure vent, include valve body (1), float (2), wishbone lever (4), of the present utility model being characterised in that, wishbone lever bearing pin (7) is gone up suit both feet torsion spring (5) and is acted on mutually with wishbone lever (4), and the corresponding exhaust port of wishbone lever (4) (17) is provided with sealing gasket (19).
2, hot-water heating automatic control pressure vent as claimed in claim 1 is characterized in that float (2) lower end has through hole (18).
3, hot-water heating automatic control pressure vent as claimed in claim 1, the connection ear (6) that it is characterized in that wishbone lever (4) has boss and is spacing with fender bracket and cooperates.
4,, it is characterized in that exhaust nozzle (12) exhaust end is provided with splashproof helmet (11) as claim 1 or 2 or 3 described hot-water heating automatic control pressure vents.
