Abstract

The utility model discloses a water pressure control system, which comprises a switch regulating valve communicated with the output end of a water replenishing pipeline, wherein the output end of the switch regulating valve is connected with an electric water replenishment regulating valve and a regulating valve in sequence; the regulating valve is connected with a circulating water system which is further connected with a water tank by a water draining expansion pipe, and the water draining expansion pipe is provided with a water draining valve; pressure transmitters are arranged between the switch regulating valve and the electric water replenishment regulating valve, and also between the electric water replenishment regulating valve and the regulating valve; the pressure transmitter is connected with the input end of a control unit; and the output end of the control unit is connected with the electric water replenishment regulating valve and the water draining valve. By adopting the technical scheme of the water pressure control system disclosed by the utility model, the system pressure of the water replenishing pipeline is fully utilized, and the increment of the production cost caused in secondary pressurization of the traditional constant-pressure water replenishing device is avoided.

Description

Water pressure control system
Technical field
The utility model relates to a kind of control system, specifically relates to a kind of constant pressure supply water control system that is applicable to closed system HVAC, power specialty etc.
Background technology
The closed system constant pressure supply water of HVAC, power specialty etc. adopts the constant pressure supply water device more than 95% at present, and system is made up of Constant pressure tank, electro connecting pressure gauge (or pressure unit), small pump etc.The first cost of investment of this system is high, and runtime system is according to moisturizing pressure frequent start-stop small pump, consumed power on the one hand, and the frequent start-stop water pump will be bigger to pump motor, the infringement of machine envelope on the other hand, and the later maintenance expense is higher.On the other hand, the Constant pressure tank inner septum can be aging, ineffective behind long-play in the constant pressure supply water device, needs to change.Constant pressure tank belongs to pressure vessel, need carry out annual test and full inspection, and testing cost is higher.
Summary of the invention
The purpose of the utility model provides a kind of unmanned of realizing, full-automatic water-supplying, pressure release, the water pressure control system of water pressure invariableness.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises the regulating switch valve that is connected with moisturizing pipeline output terminal, and the output terminal of regulating switch valve connects moisturizing electric control valve and variable valve successively, and variable valve connects circulation; Described circulation also connects water tank through the sluicing bulged tube, and on the sluicing bulged tube, is provided with draw-off valve; Between said regulating switch valve and the moisturizing electric control valve, between moisturizing electric control valve and the variable valve pressure unit is set all; Described pressure unit connects the input end of control module, and the output terminal of control module connects moisturizing electric control valve and draw-off valve.
Regulating switch valve and variable valve are solenoid valve, and all are connected with control module.
Adopt the utility model of technique scheme, have the following advantages:
1, the utility model has made full use of the system pressure of moisturizing pipeline, the increase of production cost when having avoided traditional constant pressure supply water device secondary to pressurize;
2, control module is realized automatically, is controlled in real time moisturizing electric control valve and draw-off valve, has realized unmanned; And control has guaranteed the circulation pressure stability at SP ± 0.02Mpa in real time, has guaranteed environment cooling and heating load temperature stabilization;
Can be back to water tank when 3, system's hydraulic pressure is too high and reuse, water resource waste when having avoided manual sluicing.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
Embodiment
As shown in Figure 1, the utility model comprises the regulating switch valve 2 that is connected with moisturizing pipeline 1 output terminal, and the output terminal of regulating switch valve 2 connects moisturizing electric control valve 3 and variable valve 4 successively, and variable valve 4 connects circulation 5; Above-mentioned circulation 5 also connects water tank 8 through sluicing bulged tube 6, and on sluicing bulged tube 6, is provided with draw-off valve 7.
For realizing automatically, controlling in real time; Between regulating switch valve 2 and the moisturizing electric control valve 3, between moisturizing electric control valve 3 and the variable valve 4 pressure unit 9 is set all; Pressure unit 9 connects the input end of control module 10, and the output terminal of control module 10 connects moisturizing electric control valve 3 and draw-off valve 7.
Need to prove that above-mentioned regulating switch valve 2 can be hand switch with variable valve 4, keep in use often opening; Certainly, the two also can be solenoid valve, and all is connected with control module 10, by all electrically operated valves of control module 10 controls, can realize full-automatic and unmanned like this.
The principle of work of the utility model is: when control module 10 detects circulation 5 pressure and is lower than SP-0.02Mpa according to pressure unit 9; Moisturizing electric control valve 3 is according to control module 10 signals; Give circulation 5 moisturizings, when moisturizing pressure reaches SP+0.02Mpa, close.If circulation 5 is closed when causing system pressure to be higher than SP+0.02Mpa because of mini system wherein, draw-off valve 7 will be back to water tank 8 through sluicing bulged tube 6 through the signal that receives, and the water in the water tank 8 can utilize once more.
