Serious water shortage.
To solve the above problems, many professionals start to replace magnetic valve using motor-driven valve.Motor-driven valve be powered or
In the state of person's power-off, it can slowly be turned on or off, can effectively prevent the service life of water hammer effect, extension device.But
It is to replace magnetic valve can not adapt to the real needs of heat storage water tank system operation using motor-driven valve, main cause is solar water
The state of affairs of power-off or load rejection often occurs in the electric control part of system, once using motor-driven valve, in the device of supply cold water
System cut-off, then motor-driven valve can not close automatically, system supply cold water process can not stop, continuing for heat storage water tank can be caused
Spilling water, causes serious water resource waste, while extremely serious potential safety hazard can also be brought for user.
The content of the invention
For above-mentioned the problems of the prior art, the utility model provides a kind of heat storage water tank anti-overflow system, the system
Using the technical scheme comprising motor-driven valve, the situation for opening processus aboralis chance power-off for motor-driven valve is improved, matched somebody with somebody by adding
Close the valve used and device of warning, be not in the situation of spilling water when realizing the power-off suddenly of heat storage water tank experience.
The utility model technique effect to be reached is achieved by the following technical programs：
A kind of heat storage water tank that the utility model is provided, which is put, sets gradually installation at system, including heat storage water tank water inlet pipe
Hydraulic-pressure regulating valve, electric butterfly valve, pressure-reducing valve；
Also include heat storage water tank water inlet and the ball-cock assembly being installed on inside heat storage water tank is set, the ball-cock assembly is less than storage
Boiler highest liquid level 5-10cm；
Also include setting the hydraulic pressure sensor being installed on water inlet pipe and equipment of warning.
Further, also include setting the exhaust apparatus installed at the top of heat storage water tank in said system.
Yet further, the exhaust apparatus is steam vent and venting plug, and the steam vent is located in the middle part of heat storage water tank,
The venting plug material is one kind in PVC, EVA, HDPE, PPS, PSF plastics, and the venting plug area is tank top
The 30-40% of area.
Further, the pressure-reducing valve, hydraulic pressure sensor and equipment of warning are installed on heat storage water tank installation place.
Further, the equipment of warning is buzzer siren or LED display alarm.
Further, the ball-cock assembly is copper ball-cock assembly.
The utility model has the following advantages that：Motor-driven valve replacement of solenoid valve is used in the utility model, storage can be prevented effectively from
Current are to the water hammer effect caused of magnetic valve during cold water supply for boiler, while being passed by adding ball-cock assembly and hydraulic pressure
Sensor and equipment of warning, can avoid motor-driven valve from meeting with the caused situation about can not close automatically of power-off suddenly, so as to avoid mending
To during cold water the occurrence of spilling water.
Brief description of the drawings
Fig. 1 is the schematic diagram of heat storage water tank anti-overflow system in the utility model.
Embodiment
Content of the present utility model is further described below by embodiment.
The heat storage water tank anti-overflow system used in the present embodiment is as shown in Figure 1.Heat storage water tank in the present embodiment is still adopted
With time of the prior art and the pattern of liquid level line traffic control moisturizing up and down, in heat storage water tank water volume 20%, 30%, 50%,
The 75%th, several liquid levels are set at 100% liquid level, the benefit that control system carries out cold water is limited by time and the liquid level up and down of system design
Fill.
Anti-overflow system in the present embodiment includes once setting the hydraulic-pressure regulating valve 4 of installation, electricity at heat storage water tank water inlet pipe
Dynamic butterfly valve 5 and pressure-reducing valve 6；Also include heat storage water tank water inlet and the ball-cock assembly 8 being installed on inside heat storage water tank, ball-cock assembly are set
Less than heat storage water tank highest liquid level 5-10cm；Also include setting the hydraulic pressure sensor being installed on water inlet pipe and its equipment 7 of warning.
To increase the service life, while considering using effect, selection uses copper ball-cock assembly.
In actual use, heat storage water tank 1 is connected with cold water main pipe 2, and the inflow of cold water main pipe passes through cold water
Tube valve 3 is controlled.After cold water supply water inlet, control to enter the water flow pressure of heat storage water tank by hydraulic-pressure regulating valve 4, it is electronic
Whether the control heat storage water tank of butterfly valve 5 end intakes, and pressure-reducing valve 6 is used for the stabilization for ensureing hydraulic pressure.Hydraulic-pressure regulating valve is distinguished with pressurizing valve
Located at electric butterfly valve both sides, while ensure that the stability of electric butterfly valve water inlet side hydraulic pressure and water outlet side hydraulic pressure, make to enter heat accumulation
The water flow pressure of water tank is stable, minimizes impact of the current to overall cold water supplying pipe and water tank equipment, makes heat storage water tank system
System can be constantly in steady, constant working condition.Once being powered off during water inlet is fed, electric butterfly valve 5 still enters
Row work, then cold water can continually and steadily enter heat storage water tank inside, when reaching ball-cock assembly 8, ball-cock assembly work, close water inlet
Mouthful, make no longer to intake in water tank, prevent cold water from overflowing.
System drastically changes or during any valve invalidation if there is hydraulic pressure during use, is connected to storage tank
After the hydraulic pressure sensor of side is perceived, coupled equipment of warning can send alarm sounds personnel and be handled.In maximization
Or in the heat storage water tank system in commercial Application, pressure-reducing valve 6, hydraulic pressure sensor and equipment 7 of warning are preferably attached to water storage
Case installation place, be easy to operating personnel receive warn after cistern system is investigated and overhauled immediately.The equipment of warning used
Buzzer siren or LED display alarms may be selected, is easy to use and is defined in actual conditions.
Further, exhaust apparatus 9 is additionally provided with the top of heat storage water tank in the present embodiment, exhaust apparatus is by tank top
Steam vent is constituted with hypothesis and the venting plug of steam vent upper end.Intake using the anti-overflow system in the present invention, water inlet end hydraulic pressure
Steadily, so steam vent is most appropriate located at heat storage water tank middle part.Venting plug and water tank are using be threadedly coupled, clamping etc. is normal
It is attached with connected mode, for ease of dismounting, while being applied to bear having one on heat storage water tank in view of venting plug
The swap-in of constant temperature difference, therefore venting plug material selection plasticity is good, in service life length PVC, EVA, HDPE, PPS, PSF plastics
One kind.In actual use, the 30-40% that venting plug area is set to tank top area is optimal, i.e. convenient use
And dismounting, while the thermal cycle to water tank does not cause burden.
It is last it should be noted that above example is only to the technical scheme that illustrates the utility model embodiment rather than right
It is limited, although the utility model embodiment is described in detail with reference to preferred embodiment, this area it is common
Technical staff should be understood still modify to the technical scheme of the utility model embodiment or equivalent substitution, and this
A little modifications or equivalent substitution can not also make amended technical scheme depart from the scope of the utility model embodiment technical scheme.
