Abstract
The utility model relates to a time-delay auto-control valve for a boiler moving without pressure, which is installed in the backwater main pipe of a heating system of a boiler. The utility model is characterized in that a control room is composed of a delay timer, an upper valve deck and a rubber acetabuliform membrane, and a valve body is composed of a valve plug, a spring, a valve handle and a valve flap. When a water pump is started, the water head pressure forces the rubber acetabuliform membrane to drive the valve body to move downwards so as to open the valve; when the water pump stops working, the valve body resets along with the disappearance of the water head pressure, the delay timer reacts, and the valve is turned off for time-delay for 5-10 seconds, so water-attack phenomenon of the pipe is avoided, a water return pipe is separated from the boiler, and the boiler is free from backwater pressure.
Description
The utility model belongs to hot-water heating gas equipment technical field.
At present, heating system generally changes the low-temperature hot-water boiler formula into.Relation because of building height, heating water boiler is bearing building height hydrostatic pressing and pump working pressure, and because of system's open type swelling water tank places top of building, when boiler hot-water heats up gasification, factors such as exhaust obstruction, cause boiler operatiopn to be absolutely unsafe, explosive accident is of common occurrence, has brought massive losses for the development of the national economy and the people's lives and property.
Recent years, invention unpressurized hot water boiler heating system is also arranged, but method is different.Application number 89203569.2 " unpressurized hot water boiler " utility application is to realize that boiler does not have one of pressure measure, and it is that the check valve and the safety check that surges are installed in heating network, but the structure of valve is not open.
The objective of the invention is the water-heating boiler heating system, when the circulation air pump inoperative, by the effect of autocontrol valve and one-way valve, boiler and whole heating system are separated, to pressure reduction is not transmitted mutually, boiler does not bear pressure; When water pump begins starting, autocontrol valve starts synchronously, and whole system begins circulation, and boiler is a constant no pressure point all the time, and reaching water-heating boiler does not have the operation of pressing.
This water-heating boiler does not have the operation of pressure time-delay autocontrol valve and is made up of valve body (1), bonnet (2), rubber dish barrier film (3), valve plug (4), delayer (5), valve rod (6), spring (7), flap (8), seal ring (9), bottom flange (10).Its structure is the valve body of straight-through type, and the valve body upper flange plate is equipped with bonnet, between be lined with rubber dish barrier film, form the control room; Covering valve plug under the rubber dish barrier film, valve plug and spring are equipped with in the valve rod upper end, and flap is equipped with in the lower end, forms valve body; The valve hole is equipped with seal ring, and flap is mated below seal ring, and valve opening is set in the valve body bottom, and plug wire formula bottom flange is housed, and delayer is contained on the bonnet, connects control valve.(seeing accompanying drawing)
The time-delay autocontrol valve is installed in the boiler room on the backwater main pipe, control valve water pump waterexit end, and the valve body two ends link to each other with the backwater main pipe.Its working procedure is: during starting mode of pump, water enters the control room by the control valve that is connected in pump outlet, exert pressure for rubber dish barrier film, driving rubber dish barrier film moves downward with the valve plug against the force of the spring, valve rod and flap also move downward, make the valve opening standard-sized sheet after, valve plug is blocked no longer by the confined planes on the valve body and moves downward, because of the existence of hydraulic head pressure, valve remains full-gear.When water pump stops, the water pump dynamic head disappears, valve plug, valve rod, flap are moved upward by the effect of spring, this moment is because of the resistance reverse action of delayer, move upward and slowly carry out, flap can not be suddenly with valve closing, and 5-10 is after second for process, valve closing could be avoided Water hammer of pipeline.In the output water pipe, conduit pipe is closed by one-way valve simultaneously, and boiler and heating system separate, and whole heating system is finished cyclic program one time, guarantees that boiler does not bear pressure all the time in the whole service process.
This time-delay autocontrol valve is applicable to that the employing low-temperature hot-water boiler of different building heights does not have the operation of pressure heating.Pressure-less boiler can both play a role in central heating and tall building district heating, and is practical.
This time-delay autocontrol valve guarantees that water-heating boiler does not have the operation of pressure, has safe and reliable advantage.Boiler does not have the installation investment that pressure energy reduces the manufacture cost of boiler and reduces whole heating system; Also can make waste and old bearing boiler obtain again utilizing, also save fund; Aspect multi-use,, can supply with bath water simultaneously according to its characteristics.Thereby the birth and the popularization of time-delay autocontrol valve, open for the extensive use of pressure-less boiler and to have expanded vast future.
This time-delay autocontrol valve modern design, rational in infrastructure, stable performance, installation and maintenance are convenient, and are easy to manufacture, easy popularization.
Shown in accompanying drawing: water-heating boiler does not have presses operation time-delay autocontrol valve plan view.
Claims (2)
1, a kind of water-heating boiler does not have the operation of pressure control valve, the valve body that it is characterized in that straight-through type, the valve body upper flange plate is equipped with bonnet, between be lined with rubber dish barrier film, covering valve plug under the rubber dish barrier film, valve plug and spring are equipped with in the valve rod upper end, flap is equipped with in the lower end, and flap matches with the seal ring of wherein being adorned below the valve hole, and valve opening is set in the valve body bottom, plug wire formula bottom flange is housed, delayer is housed above the bonnet.
2, do not have the operation of pressure time-delay autocontrol valve as claim 1, described water-heating boiler, it is characterized in that the mounting point is the waterexit end that the delayer upper end connects water pump, the valve body intake-outlet connects the backwater main pipe.
