Abstract
The utility model discloses an automatic pressure-stabilizing device of water heater, belonging to the pressure-stabilizing device of a hot water central heating system. When the automatic pressure-stabilizing device of water heater is arranged on the main pipe of the hot water central heating central heating system, the dynamic water pressure curve of the system can automatically stabilize within certain range, and the automatic pressure-stabilizing device of water heater can alarm and discover the failure of the system in time for protecting the normal operation of the hot water central heating system and saving energy. The automatic pressure-stabilizing device of water heater is mainly composed of a pressure-stabilizing control box, an alarm part and a component for supplementing water and draining water. The automatic pressure-stabilizing device of water heater is suitable for stabilizing pressure for regional hot water central heating system.
Description
The utility model relates to a kind of pressurization methods of hot water central heating forced circulation system, belongs to the stable-pressure device of hot water central heating system, needing to be suitable for the user of forced circulation hot water heating.
Existing hot water system adopts expansion tank and small pump to cooperate the level pressure method of running water, its application conditions and heating area size all are subjected to certain restriction in actual use, and can not know in time that system breaks down, and has caused economic losses such as energy device damage.
Task of the present utility model is to design a kind of moving hydraulic curve position stability of the hot water central heating circulatory system that can make in certain limit, and make system obtain a safe and reliable pressure stability working condition automatically, wide accommodation, the heating zone is big, the hot water heating automatic voltage regulator of discovery accident in time.
The utility model is finished as follows: this device is mainly by the voltage stabilizing control cabinet, and three parts of part and moisturizing sluicing parts of reporting to the police constitute.As Fig. 1, electro connecting pressure gauge 1,2 is housed in its voltage stabilizing control cabinet 3, electro connecting pressure gauge 1,2 is installed on the steel pipe 5, and steel pipe 5 usefulness flanges 12 are connected on the house steward 14, and table 1,2 is in order to measure heating circulation system pressure.Electric bell 8 and siren 9 are formed the warning part, and connect with voltage stabilizing control cabinet 3 respectively.Moisturizing sluicing parts can be made up of small pump 7, magnetic valve 4 and supporting valve 13, non-return valve 6.Small pump 7, magnetic valve 4 are connected between house steward 14 and the voltage stabilizing control cabinet 3.Also has water tank 10 in this device, as the water body that stores supply and bleed-off system.A safety valve is installed on house steward 14 in addition.
Fig. 1 is a scheme of installation of the present utility model.
Fig. 2 is electric control theory figure of the present utility model.
With reference to Fig. 1, Fig. 2 describes principle of the present utility model and working condition in detail, electricity connects the operating pressure of the Pressure gauge 1 control hot water central heating circulatory system (hereinafter to be referred as system), i.e. minimum operating pressure in the table 1 lower limit indication mechanism, maximum working pressure in the table 1 higher limit indication mechanism, when system's internal pressure descends, table 1 pointer contact lower limit, electric by voltage stabilizing control cabinet 3 commander's small pumps 7 electric motor startings, water is sent into system from water tank 10, system's internal pressure rises on the table 1 and prescribes a time limit, the indicator contact upper limit electricly stops by voltage stabilizing control cabinet 3 commander's small pumps 7 motors.System's internal pressure is between table 1 bound the time, and the expression system is in operate as normal.Electro connecting pressure gauge 2 is used for the control system safe pressure, and table 2 higher limit is higher than table 1 higher limit 0.03-0.05MP
a, table 2 lower limit is lower than table 1 lower limit 0.02-0.05MP
a, the relieving pressure of safety valve 11 should be near maximum safety pressure power in the system (upper limit maximum of giving as table 2), but can not surpass its force value.If table 1 and commander's transmission are malfunctioning, system's internal pressure continues to rise, when reaching table 2 pointer contact higher limit, the voltage stabilizing control cabinet of this device is opened the sluicing step-down of magnetic valve 4 systems, electric bell 8 is reported to the police simultaneously, tells the operator on duty hypertonia, should notice that observing system pressure changes.If magnetic valve 4 breaks down or other reason, cause system pressure continue to rise, and during near system's maximum safety pressure power, safety valve open system sluicing step-down has guaranteed the normal and safety of system.If " metalling run out " too much or other reason, the system internal pressure of causing drops to table 2 time in limited time, and table 2 pointer just contacts the low pressure limit value, electricly works by voltage stabilizing control cabinet 3 indication sirens 9, the low pressure situation has appearred in warning operator on duty system, should in time get rid of.
The utility model can be according to user's circulatory system reality, name with caliber and to be φ 108, φ 159 φ 219 ... series of products, the voltage stabilizing control cabinet 3 of automatic voltage regulator is assembled on the steel pipe 5, steel pipe 5 usefulness flanges 12 are connected on the house steward of system 14, transmit signal with lead or cable between voltage stabilizing control cabinet 3 and electric bell 8, the siren 9, electric bell 8, siren 9 can be respectively installed to the place of being convenient to observe.The model of small pump 7 can be determined according to circulatory system size and heating regional extent by the designer.
The utility model with make pressurization methods relatively with expansion tank, it is big to adapt to the heating zone, can report accident and early discovery accident. Make pressurization methods relatively with cooperate running water with small pump, this device is adapted to running water imperfection area, and is safe, reliable, energy-conservation, automaticity is high. From economically with front two kinds of pressurization methodses relatively, for the first time investment of this device but the loss of accident occurs from use procedure greatly, is worthwhile and economical. Along with the development of society, require environmental contamination reduction and energy savings, the utility model will be subjected to numerous users and welcome.
3000 meters * 2000 meters in the mining area, Shaanxi heating zones take dwelling house as the master of this device (generally are four floors, the highest is five floors) in, the total caliber of the circulatory system is φ 325, the boiler room per hour produces the hot water of 9,600,000 kilocalories, after adopting scheme shown in Figure 1 to use 100 days, with several years ago four the same period heating season relevant data mean value relatively, economize on water 680 cubic metres, economize on coal 200 tons, economize on electricity 3200 degree, equipment maintenance cost has reduced half, also reduces management and maintenance personnel's workload simultaneously, it is reliable to report to the police, and is subjected to user of service's favorable comment and service worker and praises.
