In central heating and cooling system, rational pressure distribution is the key that pipe network normally runs.In existing system, once adopt the switch of hand control valve, and utilize electrode points Pressure gauge to control the multiple constant pressure supply water modes such as the unlatching of small pump or closedown.From control angle, these modes can not the more level and smooth problem solving pressure inequality in pipeline more in time.From energy-saving and cost-reducing angle, they need to waste a large amount of human costs, also add the expense of equipment maintenance.
Releasing for hypertonia on existing constant pressure water compensation apparatus, only depends on the safety valve in system.The instability of releasing of safety valve, and sensitivity is general.Often there is superpressure state to fail to release in time, cause system pressure high, report to the police.Or release and too much can not close in time, cause system ftercompction again.
The Chinese patent of Chinese patent CN201006339Y discloses a kind of degasser, this device comprises vacuum degassing machine, small pump, vacuum tank and base composition, be connected with main pipe after one end connection moisturizing magnetic valve of vacuum degassing machine filling pipe, water inlet pipe separates two branch roads, every bar branch road is connected to a small pump, two water sides going out water pump are connected with main pipe, electrical nodes force pipe, vacuum tank, sluicing magnetic valve, safety valve and manual drain valve are also arranged on main pipe, when this device pressure release, manually drain valve manual adjustments sluices, it is large that operation controls hydraulic pressure difficulty, inaccuracy, be easy to occur controlling inaccurate phenomenon.
Summary of the invention
Object of the present invention be exactly provide a kind of to overcome defect that above-mentioned prior art exists and automatically regulate, easy to operate, Double-pressure-relief, structure simple, the constant pressure supply water system of the solenoid control that cost is low.
Object of the present invention can be achieved through the following technical solutions:
A kind of constant pressure supply water system of solenoid control, for maintaining the isostasy of water pipe, described water pipe is connected with replenisher tank, described water pipe comprise connect successively moisturizing arm, moisturizing supervisor and moisturizing pump line, it is characterized in that, described moisturizing pump line is provided with small pump, and described moisturizing supervisor is provided with Pressure gauge, described moisturizing arm is provided with safety valve, and described constant pressure supply water system also comprises the constant pressure arrangement be connected with water pipe;
When the hypertonia on water pipe needs pressure release, automatically detected the pressure on water pipe by constant pressure arrangement, and carry out pressure release action, maintain the pressure stability on water pipe.
Retaining original safety valve and manual Drainage valve, obtain pressure value by observing Pressure gauge, and handling safety valve carrying out pressure release, to reach Double-pressure-relief protection, more reliably.
Described constant pressure arrangement comprises and to be arranged in parallel the pressure relief pipe on moisturizing is responsible for, the magnetic valve be arranged on pressure relief pipe with moisturizing arm, to be arranged on pressure sensor and controller that moisturizing is responsible for, and described controller is connected with magnetic valve and pressure sensor respectively.
Described moisturizing arm is also provided with dirt separator, described moisturizing supervisor is also provided with filter.
Described small pump is frequency conversion small pump.
The pressure normal range (NR) of described water pipe is 0.48-0.52MPa.
Described safety valve is spring loaded safety valve.
Described magnetic valve is direct-acting electromagnetic valve.
Described Pressure gauge is distance-transmission pressure gauge.
Compared with prior art, the present invention has the following advantages:
One, automatically regulate, easy to operate: native system measures the pressure in water pipe by pressure sensor, and by signal transmission to controller, controller determines whether to need pressure release or pressurization by the range hydraulic pressure of setting, and controls small pump pressurization and magnetic valve pressure release makes pressure recover in water pipe to normal range (NR).
Two, Double-pressure-relief: native system is provided with safety valve on moisturizing arm, and be provided with pressure relief pipe on moisturizing arm side, magnetic valve on pressure relief pipe and safety valve cooperatively interact, by the pressure in Pressure gauge and the manual pressure release of safety valve and the releasing pressure automatically two ore control water pipe of controller and magnetic valve, more safe and reliable.
Three, structure is simple, and cost is low: native system only with the addition of constant pressure arrangement on original pipeline, and structure is simple, and improvement cost is low, applied widely.
