Description
Technical field
The utility model relates to a kind of constant pressure water compensation apparatus, particularly relates to a kind of automatic constant pressure exhaust water replanishing device.
Background technology
At present, the heating of more than 90% and air conditioner water circulating system, often be subject to the puzzlement of air problem, the large quantity of air (free gas in water and dissolved gas) existed in water system will cause the appearance of following series of problems: the harm, noise pollution etc. of cavitation (in, the heat exchange efficiency affecting end-equipment and dehumidification function, corrosion and microorganism.Existing limit pressure water feeding equipment, its mode many employings high expansion water box or pressurized tank and electro connecting pressure gauge realize, have that volume is large, level pressure inaccuracy, do not have degassing function, can not 100% absorption system swell increment.According to Henry's law, gas is solubility and water temperature and pressure correlation in water, at a certain temperature, is down to minimum limit with the loss of gas consumption and system unit, thus can reduce the harm that system waste water produces environment as much as possible.
Summary of the invention
For the deficiencies in the prior art, the utility model proposes and can eliminate gas, have the device of automatic constant pressure exhaust moisturizing, this device can solve cavitation (in, gas blocks up problem, extends the water pump operation life-span, improves running efficiency of system.
The utility model is achieved by the following technical solution: a kind of automatic constant pressure exhaust water replanishing device, comprise normal pressure tank, be communicated with the pipeline of normal pressure tank and system return pipe, and the water pump be arranged on pipeline, described outlet conduit arranges electro connecting pressure gauge, for detecting and the data signal of transmission system pressure, described pipeline comprises blowdown line, ftercompction pipeline and moisturizing pipeline, described normal pressure tank is arranged Stress control table, for measuring tank interior pressure.
Further, described normal pressure tank top arranges air bleeding valve.
Further, the start and stop of described water pump are controlled by control cabinet, the signal input part of described control cabinet is connected with the signal output part of electro connecting pressure gauge with Stress control table respectively, the signal output part of control cabinet respectively with the motor of water pump, and be arranged on the first valve on pipeline, the second valve, the 3rd valve be connected.
Further, the first described valve, the second valve, the 3rd valve are magnetic valve.
Further, between described water pump water outlet pipeline and system inlet channel, the ball valve being with filter is also set.
Further, between described inlet channel and water pump, also gate valve is set, by closing gate valve, anti-sealing backflow can enters water pump; Described outlet conduit is installed check-valves and stop valve.
The utility model compared to existing technology, has following beneficial effect:
1. the utility model system adopts digital integration to control, and by pressure sensor device, transmission system pressure and tank body water level data signal precisely control the running of each unit.
2. the utility model can eliminate gas, there is automatic constant pressure, the function of exhaust moisturizing, extend the water pump operation life-span, improve running efficiency of system.
3. the utility model is by control cabinet by-pass valve control, can automatically discharge the too much water yield, discharge the partial pressure of system superelevation, to ensure tank body not pressurized.

Wherein: 1-pipeline, 2-water pump, 3-electro connecting pressure gauge, 4-Stress control table, 5-air bleeding valve, 6-control cabinet, 7-first valve, 8-second valve, 9-the 3rd valve, 10-ball valve, 11-gate valve, 12-check-valves, 13-stop valve.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in the figure.A kind of automatic constant pressure exhaust water replanishing device, comprise normal pressure tank, be communicated with the pipeline 1 of normal pressure tank and system return pipe, and the water pump 2 be arranged on pipeline, described outlet conduit is arranged electro connecting pressure gauge 3, for detecting and the data signal of transmission system pressure, described pipeline 1 comprises blowdown line, ftercompction pipeline and moisturizing pipeline, described normal pressure tank is arranged Stress control table 4, for measuring tank interior pressure.
Further, described normal pressure tank top arranges air bleeding valve 5.
Further, the start and stop of described water pump 2 are controlled by control cabinet 6, the signal input part of described control cabinet 6 is connected with the signal output part of electro connecting pressure gauge 3 with Stress control table 4 respectively, the signal output part of control cabinet 6 respectively with the motor of water pump 2, and be arranged on the first valve 7, second valve 8 on pipeline, the 3rd valve 9 is connected.
Further, the first described valve 7, second valve 8, the 3rd valve 9 are magnetic valve.
Further, the ball valve 10 being with filter is also set between described water pump water outlet pipeline and system inlet channel.
Further, between described inlet channel and water pump 2, gate valve 11 is also set, realizes water pump 2 the using and the reserved, by closing gate valve, anti-sealing backflow can enter water pump 2; Described outlet conduit is installed check-valves 12 and stop valve 13.
During system cloud gray model, water pump 2 motor runs well, when be arranged on the Stress control table 4 on normal pressure tank show normal pressure tank internal pressure higher time, control cabinet 6 controls the first valve open, swelling water is flowed out from normal pressure tank by pressure release, ball valve 10 through band filter filters, and ensures that the water quality of inflow system is good; When be arranged on the Stress control table 4 on normal pressure tank show normal pressure tank internal pressure on the low side time, control water pump 2 by control cabinet 6, from ftercompction pipeline introduce water carry out ftercompction.Outlet conduit being arranged electro connecting pressure gauge 3, when electro connecting pressure gauge 3 shows numerical value lower than setting value, control the 3rd valve 9 by control cabinet 6 and open, increasing system pipeline pressure by mending running water.Cycle of higher pressure water enter in exhaust process normal pressure tank reduce pressure after gas-water separation, the gas of precipitation enters air via normal pressure tank top vent valve 5.
