The utility model comprises a water storage tank, a water supply valve, a water supply pipe, a boil cylinder and a water replenishing tank; the water storage tank is communicated with the water replenishing tank through the water supply valve and the water supply pipe; the water replenishing tank is communicated with the boiler cylinder through the water replenishing valve and the water replenishing tank; a balance pipe is installed between the water replenishing tank and the boiler cylinder; the balance pipe is provided with a balance valve; the top of water replenishing tank is provided with a pressure release pipe; and the pressure release pipe is provided with a pressure relief valve. The water supply device has the advantages of energy saving, safe and reliable operation, no noise and pollution, and the like, and is applicable to various types of hot water and steam boilers.
Description
Technical field
The utility model relates to the boiler water supply equipment technical field, particularly relates to a kind of boiler pressure balance water supply installation.
Background technology
At the boiler of usefulness, having very, major part provides steam or hot water to the user with regard at present.Steam that they are exported or hot water do not return drum.So this class boiler must often replenish qualified water, just can keep continual safe operation.To the mode of boiler replenishing water, be mostly to adopt the mode of centrifugal high pressure water pump pressure now to the drum water filling.By analysis, be not difficult to find, have the following disadvantages with the mode of high pressure centrifugal pump to boiler replenishing water:
At first be, current are in being transferred process, be under the situation of high flow rate, constantly flowed to and fluidised form, and be subjected to the high speed shear of pump rotor: especially adopt in the operating mode of multistage polyphone centrifugal pump current the suddenlyd change flow direction, fluidised form by flip-flop, situation by high speed shear is more serious, so just make being consumed in a large number by head of current, cause the operating efficiency of centrifugal high pressure water pump low, i.e. the energy consumption height.
Next is, because the centrifugal high pressure pumping system involves pot motor, power train, slipper seal system, the pump housing and rotor, conveyance conduit etc., and all be state work, be easy to be out of order, promptly bring hidden danger and maintenance work numerous and diverse safe operation at high rotating speed High Voltage.
Also have, high pressure centrifugal pump is because rotating speed height during operation, and suffered pressure is big, so bigger noise is arranged, environment is polluted.
Summary of the invention
The purpose of this utility model provides a kind of boiler pressure balance water supply installation, overcome present with high pressure centrifugal pump to the existing energy consumption height of the mode of boiler feedwater, have hidden danger and maintenance work numerous and diverse to safe operation, environment is caused deficiencies such as noise pollution.
The utility model is achieved by following technical proposals.
The utility model comprises water storage tank, water-supply valve, feed pipe, boiler drum, is provided with water supply tank, as special usefulness of giving the boiler drum moisturizing.Water storage tank makes to store the usefulness at treated qualified water source, and water storage tank is communicated with water supply tank by water-supply valve, feed pipe.Water supply tank is communicated with boiler drum by water compensating valve, filling pipe, be provided with balance pipe between water supply tank and the boiler drum, balanced valve is housed on the balance pipe, and relief tube is equipped with at the top of water supply tank, and relief valve is housed on the relief tube, setting height(from bottom) is concerning the utility model, most important, flow into the target that needs supplementing water in order to reach the gravity that makes full use of water, should make has enough differences of height between them, the caliber of aqueduct amplifies as far as possible simultaneously, to reduce flow resistance.In the utility model, the permission lowest water level line of water supply tank is fair with the permission maximum water level of boiler drum at least, and the permission lowest water level line of water storage tank is fair with the permission maximum water level of water supply tank at least.Here water storage tank is that the position is the highest, but because it is open to atmosphere, horizontal plane does not have impressed pressure, therefore, if water treatment procedure with the platform of water storage tank sustained height on carry out, then need not increase the water pump that water storage tank supplies water, as long as utilize the pressure head of running water pipe network enough.Even use water supply pump, as long as also select the high efficiency water pump of low pressure and mass flow for use; Simultaneously, consider that water supply tank is to utilize some in order to pressure balanced pressure head to the boiler drum moisturizing, the energy that the two addition consumed also is to be significantly less than the energy that high-pressure hydraulic pump directly supplies water and will consume to boiler drum.
The utility model can also can be controlled with automatic by manually-operated in implementation process.As long as water-supply valve, water compensating valve, balanced valve, relief valve are all used instead motor-driven valve, be equipped with automatic control electric wiring again and get final product.
Compare with prior art, the utlity model has following beneficial effect:
1. because in feedwater and the moisturizing process, the fluidised form of current is not really serious turbulent flow or even laminar flows, and the situation of sudden change direction and sudden change shape significantly reduces, so, the suffered resistance of current is very little, consume can head and directly compare with high-pressure hydraulic pump and to want much less to the boiler drum water filling, therefore, saved the energy.
2. operating ratio is more safe and reliable, and long service life has been saved the expense and the man-hour of keeping in repair.
3. in service do not have a noise, free from environmental pollution.
Description of drawings
Accompanying drawing is a scheme of installation of the present utility model.
Among the figure: 1. boiler drum, 2. water supply tank, 3. water storage tank, 4. balanced valve, 5. balance pipe, 6. water compensating valve, 7. filling pipe, 8. relief valve, 9. relief tube, 10. water-supply valve, 11. feed pipes.
The specific embodiment
All filled water when boiler drum 1 and water supply tank 2 and water storage tank 3, under the situation that each valve is all closed, boiler normally moves.Boiler is through after a while operation, and the water level of boiler drum 1 has dropped to lowest water level, and needed moisturizing this moment.Operating sequence is: balanced valve 4 is opened by elder generation, and the pressure in the boiler drum 1 makes the pressure in the water supply tank 2 equate with boiler drum 1 interior pressure by the transmission of balance pipe 5.Then, open water compensating valve 6, the water in the water supply tank 2 is just because the effect of gravity flows into boiler drum 1 by filling pipe 7.After supplying water, close balanced valve 4 and water compensating valve 6, open relief valve 8, allow water supply tank 2 interior overbottom pressure discharge by relief tube 9, open water-supply valve 10 again, the water in the water storage tank 3 just flow to water supply tank 2 by feed pipe 11.Then close relief valve 8 and water-supply valve 10 after water supply tank 2 is supplied water, wait for next moisturizing operating process.
