Description
The utility model relates to a kind of hot-water boiler automatic voltage regulation water replanishing device, and this device can guarantee the safe and economical boiler operation to the boiler replenishing water step-down of boosting and sluice.
The traditional approach of hot-water boiler moisturizing and voltage stabilizing is realized by feed pump, elevated tank, in the process of boiler operatiopn, require the fireman often to observe instrument such as hydraulic pressure, water level, and careful operation, otherwise will make boiler water shortage, the lighter makes the equipment of steaming impaired, and weight person will cause serious consequence, in addition, elevated tank have that construction investment is big, voltage regulation performance is poor, easily leak, easily freeze, the deficiency of soft water waste and inconvenient maintenance.
The purpose of this utility model is to provide a kind of hot-water boiler automatic voltage regulation water replanishing device, and this device can be according to the variation of boiler blow-down water pressure, in time boiler is implemented the moisturizing step-down of boosting and sluice, and guarantees the boiler voltage regulation operation.
The purpose of this utility model is achieved in that a kind of hot-water boiler automatic voltage regulation water replanishing device, a vacuum tank is arranged, this jar internal upper part inflation bottom water-filling, pressure controller and electro connecting pressure gauge are equipped with in the top of this jar, the bottom is connected to air bleeding valve, the pipeline of bottom is communicated with the boiler blow-down water pipe, and is communicated with storage tank by the pressure release magnetic valve; The feed pump outlet is communicated with the supply pot bottom, and inlet valve is installed at the top of this supply jar, and top replenishes mouth by check-valves and vacuum tank and is communicated with; Feed pump, pressure controller, electro connecting pressure gauge and pressure release magnetic valve are electrically connected with control circuit.When the utility model uses, according to steam generator system voltage stabilizing requirement, capping force value in pressure controller, and threshold pression value, in the process of steam generator system operation, vacuum tank is communicated with the boiler blow-down water pipe all the time, when the pressure of steam generator system is lower than upper limit force value, water in the vacuum tank is from the moisturizing of trend steam generator system, carrying out along with the moisturizing process, gas pressure descends with water level in the vacuum tank, when its pressure is reduced to the threshold pression value, the pressure controller action, start feed pump, to vacuum tank tonifying Qi moisturizing, after the pressure in the vacuum tank reached upper limit force value, feed pump stopped automatically by the supply jar, at this moment, water in the supply jar is back in the storage tank automatically, and under the effect of atmospheric pressure, the inlet valve of supply tank top is opened, make gassy in this jar, the every startup of feed pump once, all will be in vacuum tank the tonifying Qi moisturizing once, gas volume increases gradually in the vacuum tank, water level constantly descends thereupon, when water level was reduced to the position that air bleeding valve limits, this valve was opened, and discharges unnecessary gas.When the expansion of steam generator system hot water, hot water will be back in the vacuum tank, make water level rising in this jar, gas pressure increases gradually, and when pressure reached the limiting pressure value of electro connecting pressure gauge setting, the pressure release magnetic valve was opened, water in the vacuum tank is let out and is got back to storage tank, thereby has guaranteed the boiler voltage regulation operation.
Compared with the prior art the utility model has following advantage:
1, owing to vacuum tank internal upper part inflation bottom water-filling, to boiler water supply, voltage stabilizing is good by air pressure, when steam generator system produces water attack, can play cushioning effect, prevents to cause device damage such as valve because of pressure rising suddenly;
2, owing to replaced high expansion water box, not only reduced construction investment but also be convenient to the ground maintenance with vacuum tank;
3, control circuit can guarantee under-voltage automatic water supplement, overvoltage sluicing protection, and degree of changing into height has reduced fireman's labour intensity automatically;
4, when the unexpected loss of power accident took place, vacuum tank still can be kept water supply.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, structural representation of the present utility model
Fig. 2, electrical schematic diagram of the present utility model
Referring to accompanying drawing 1, the utility model has a vacuum tank 11, this jar internal upper part inflation bottom water-filling, pressure controller 10 and electro connecting pressure gauge 17 are equipped with in the top of this jar, the bottom is connected to air bleeding valve 7, and the pipeline of bottom is communicated with the boiler blow-down water pipe, and is communicated with storage tank 12 by pressure release magnetic valve 8; Feed pump 1 outlet is communicated with supply jar 2 bottoms, and inlet valve 3 (model H12X-25) is installed at the top of this supply jar, and top replenishes mouth 6 by check-valves 4 (model H44T-10) and gate valve 18 with vacuum tank and is communicated with; Feed pump, pressure controller, electro connecting pressure gauge and pressure release magnetic valve are electrically connected with control circuit 9.Air bleeding valve (model P21T-4) is installed in the vacuum tank bottom on the sidewall at 200～300 millimeters places, vacuum tank bottom, can only exhaust can not draining, be provided with gate valve between air bleeding valve and the vacuum tank, easy access, vacuum tank replenishes mouth and is located at vacuum tank top on the sidewall at 250～350 millimeters places of air bleeding valve.The model of inlet valve is H12X-2, can only be air-breathing can not exhaust, for improving operating safety factor, the safety valve 5 (model A27W-10T) in parallel at pressure release magnetic valve place, when the vacuum tank internal pressure surpasses the limiting pressure value of electro connecting pressure gauge setting, safety valve is opened, and together the water in the vacuum tank is let out fast with the pressure release magnetic valve and is got back to storage tank.Referring to accompanying drawing 2, control circuit of the present utility model comprises moisturizing control circuit 13 and pressure release control circuit 14, in the moisturizing control circuit, constitute control loop, control the start and stop of feed pump according to the variation of vacuum tank internal pressure by (manual, automatic) pole changer 15, pressure controller 10 (model YWK-50-C) and interchange contact C1; In the pressure release control circuit, constitute control loop by (manually, automatically) pole changer 16, electro connecting pressure gauge 17 and auxiliary reclay Z1, normally open contact Z11, Z12 and pressure release magnetic valve by relay Z1 constitute the execution loop, constitute the loop that resets by electro connecting pressure gauge 17, auxiliary reclay Z2 and normally closed interlock Z21 thereof, when vacuum tank sluices through the pressure release magnetic valve, this loop conducting when its force value is lower than the lower limit that electro connecting pressure gauge sets, with the pressure release closed electromagnetic valve, the pressure release control circuit resets.In order further to improve reliability, two feed pumps can be set, be used alternatingly, in order further to improve the economy of the utility model operation, can use the work of computer transduce controller control feed pump.
