Abstract
The utility model relates to a safety water level self-control valve for an atmospheric boiler, which is suitable for atmospheric boilers used for the enforced circulation with additional pressure in tall buildings or heating or industrial heating systems, etc. The utility model is characterized in that the valve is provided with a working cylinder controlled by a liquid-operated switch, the inner part of the working cylinder is provided with a piston and a ball float valve which is used for adjusting the opening size and the closure of the valve, controls the water level and has a water outlet which can be connected with a pipeline, and the upper end of a boiler is provided with a low water level water tank communicated with air. The utility model has the advantages of safety, closed cycle, energy saving, practicality, reliable operation, no noise pollution, etc.
Description
The present invention relates to the safety water level of atmospheric boiler control valve, be applicable to normal-pressure boiler.For for the skyscraper heating of pressure system circulation or industrial heating system etc.
Normal-pressure boiler is used for skyscraper heating or the industrial heating system for the circulation of pressure system at present.In order to make normal-pressure boiler not bear pressure, generally all adopt to be higher than the bigger recovery tank of boiler.Boiler hot-water is transported to heating system or industry heating user by circulating pump.For keeping boiler water level, backwater enters the normal-pressure boiler heating again after a plurality of ball-cock assemblys enter recovery tank, form the open circuit circulation.But have the following disadvantages: the ball-cock assembly import is big, exports lessly, and delivery port can't be taken over the road.The draining flow velocity is big, and delivery port is big apart from water tank dynamic water level distance, enters recovery tank through one section space, produces noise pollution.The part heat distributes in the space, causes energy utilization rate low in the air, the safe operation poor reliability.
The objective of the invention is to design a kind of noise-less pollution in order to overcome the deficiency of prior art.The reliable automatic control valve for safety water level of atmospheric boiler of energy-saving safety operating.
To achieve these goals, the present invention has adopted following technical proposal.
Automatic control valve for safety water level of atmospheric boiler comprises the high water level case that rises of splashing, heating system, and there having the control of surging to open to be big, the little and working cylinder of closing.Delivery port can be taken over the ball-cock assembly on road, and circulating pump, normal-pressure boiler upper end lead to the low water level water tank of atmosphere.
Owing to adopt technique scheme, the present invention compared with the prior art, automatic control valve for safety water level of atmospheric boiler has compact conformation, but closed cycle, noise-less pollution, advantage such as energy-conservation, practical, safe, reliable.
Description of drawings:
Fig. 1: be the automatic control valve for safety water level of atmospheric boiler system diagram.
Fig. 2: be the automatic control valve for safety water level of atmospheric boiler structure chart.
Fig. 3: be to take the floating ball valve structure figure that the road can be taken in the mouth of a river out of.
Fig. 4: be to take the ball-cock assembly that the road can be taken in the mouth of a river out of, lead to the low water level water tank of atmosphere, the normal-pressure boiler connection layout.
Accompanying drawings further describes as follows to the utility model:
The utility model comprise high water level splash rise case (1), heating system (2), working cylinder inlet pipeline (4), working cylinder discharge pipe line (5), ball-and-seat (7), circulating pump (8), lead to atmosphere low water level case (9), take the mouth of a river out of and can take over the ball-cock assembly on road (6), automatic control valve for safety water level of atmospheric boiler (3), normal-pressure boiler (10).
Automatic control valve for safety water level of atmospheric boiler is provided with the control of surging and opens working cylinder large and small and that close.As shown in Figure 2, valve body (11), cylinder body (12), guide plate (13), flap (14), intake antrum (15), water chamber (16), piston (17), delivery port (18), water inlet (19), valve rod (20), valve pawl (21).Take the mouth of a river out of and can take over the ball-cock assembly on road (6), as shown in Figure 3: valve seat (22), valve body (23), valve plug (24), switch rocking arm (25), ball float (26), pipe connect (27), water return pipeline (28).Take the ball-cock assembly that to take over the road in the mouth of a river out of and lead to the low water level water tank of atmosphere and being connected of normal-pressure boiler, as shown in Figure 4: take the mouth of a river out of and can take over the ball-cock assembly on road (6), water return pipeline (28), normal-pressure boiler leads to the main line (29) of atmosphere, normal-pressure boiler (10), when work, circulating pump is with the hot water sucking-off of normal-pressure boiler, carry toward heating system and working cylinder inlet pipeline (4) and go to intake antrum (15), when low water level case (9), when water level descends, take the mouth of a river out of and can take over the just unlatching automatically of ball-cock assembly on road, the water of water chamber (16), by working cylinder discharge pipe line (5), through ball-cock assembly outlet pipeline (28), enter the main line (29) that leads to atmosphere, flow back to boiler, piston (17), on opened valve rod and mentioned flap, valve is just opened, main backwater enters normal-pressure boiler (10), carry out closed cycle, when flow was excessive, the low water level cistern water level that leads to atmosphere rose, and takes the mouth of a river out of and can take over the ball float of the ball-cock assembly on road (26), levitating moving switch rocking arm (25) of generation, promote valve plug (24), move, carry out the adjusting of water yield to valve seat (22) direction.Valve plug (24) is in to be opened or semi-open state, makes upper and lower the moving of piston of working cylinder carry out the main valve adjusting.The highest when spacing when reaching on the water level of the low water level water tank that leads to atmosphere, taking the mouth of a river out of can take over the ball-cock assembly on road and close, working cylinder on the automatic control valve for safety water level of atmospheric boiler, the water of cavity of resorption (15) and epicoele (16) transfers static pressure to by dynamic pressure, 2 backwater holes and piston (15) are arranged on the piston (17), with cylinder body (12), interior sectional area through the gap makes the water of cavity of resorption (15) overflow to epicoele (16), and the deadweight of piston (17) and flap (14) descends and closes.
The present invention can be used for uses such as the skyscraper heating of forced circulation or industrial heating system at normal-pressure boiler, has use value and economic worth widely.
