Abstract
The invention discloses a feedback signal access sound-light alarm device of a pressure fluctuation pre-stop valve. The feedback signal access sound-light alarm device comprises a pressure transmitter, a control unit, a first electromagnetic valve, a second electromagnetic valve, a sound-light alarm device body and the pressure fluctuation pre-stop valve. The pressure fluctuation pre-stop valve is installed on a conveying pipeline. The pressure transmitter is connected to the pressure end of the pressure fluctuation pre-stop valve through a guide pipe. The pressure transmitter is connected with the control unit. The control unit is connected to the two sides of the valve rod end of the pressure fluctuation pre-stop valve through the first electromagnetic valve and the second electromagnetic valve. Meanwhile, the sound-light alarm device body is connected to the control unit. By means of the feedback signal access sound-light alarm device, any action of the pressure fluctuation pre-stop valve can be fed back to an operator in time, equipment situations are grasped in time, losses are reduced, and convenience is provided for the operator.
Description
Technical field
The present invention relates to Valve controlling field, specifically a kind of pressure surge stops valve feedback signal access acoustic-optic alarm in advance.
Background technique
In the continuous sustainable development of social economy, city domestic water constantly rises, reasonable allocation of water resources, ecological protection demand are higher, are to ensure town water supply and ecological protection etc., seem particularly important to the reasonable disposition of water resources.The utilization of the water resources in mountain area and protection are needed to carry out reasonable disposition; give full play to benefit; by duct arrangement, town water supply, displacement lake poor-quality water, control water, control source can be provided to cut the protection such as dirt, water-saving and emission-reducing and administer, make urban development and ecological protection sustainable and healthy development.
At present, in the course of conveying at various water source, the unlatching of water pump, closedown and power-off cause the pressure surge caused during termination of pumping, and the water hammer that now pumping plant occurs can produce great collapsing force, and the immense pressure ripple that water hammer produces cannot discharge timely, causes very large damage to water pump pipe network.Therefore need to improve existing water pump pipe network and valve, to reduce the destruction of pressure wave to pipe network.
Summary of the invention
A kind of pressure surge is the object of the present invention is to provide to stop valve feedback signal access acoustic-optic alarm in advance, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technological scheme:
A kind of pressure surge stops valve feedback signal access acoustic-optic alarm in advance, comprise pressure transmitter, control unit, the first solenoid valve, the second solenoid valve, audible-visual annunciator and pressure surge and stop valve in advance, described pressure surge stops valve in advance and is arranged on aqueduct, the pressure end that pressure surge stops valve in advance has pressure transmitter by tubes connection, pressure transmitter Access Control unit, control unit is connected to respectively by the first solenoid valve and the second solenoid valve the valve rod end that pressure surge stops valve in advance, control unit accesses audible-visual annunciator simultaneously.
As the further scheme of the present invention: described first solenoid valve and the second solenoid valve are connected to the both sides that pressure surge stops the valve rod end of valve in advance.
Compared with prior art, the invention has the beneficial effects as follows: by the present invention, achieve pressure surge in advance only any action of valve feed back to operator all in time, timely grasp equipment situation, reduces the loss, for operator provide convenience.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-pressure transmitter; 2-control unit; 3-first solenoid valve; 4-second solenoid valve; 5-audible-visual annunciator; 6-pressure surge stops valve in advance.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of pressure surge stops valve feedback signal access acoustic-optic alarm in advance, comprise pressure transmitter 1, control unit 2, first solenoid valve 3, second solenoid valve 4, audible-visual annunciator 5 and pressure surge stop valve 6 in advance, described pressure surge stops valve 6 in advance and is arranged on aqueduct, the pressure end that pressure surge stops valve 6 in advance has pressure transmitter 1 by tubes connection, pressure transmitter 1 Access Control unit 2, control unit 2 is connected to respectively by the first solenoid valve 3 and the second solenoid valve 4 both sides that pressure surge stops the valve rod end of valve 6 in advance, control unit accesses audible-visual annunciator 5 simultaneously, the first solenoid valve 3 and the second solenoid valve 4 is opened or closed to control unit 2 according to setting value, make audible-visual annunciator 5 connect simultaneously and sound and glisten, and the sound of valve opening and pass valve is distinct, it is open and close that operator can stop valve 6 in advance by different sound alarm determination pressure surges.
Pressure surge stops valve 6 in advance and is mainly used in reducing due to water pump unlatching, closedown or power-off and causing the pressure surge caused during termination of pumping, thus protection water pump pipe network system.When range of pressure fluctuations is lower than low voltage value or exceed high-voltage value, control unit 2 can control solenoid pilot valve forces main valve to open sluicing release pressure, in the valve closing stage, possesses the function preventing secondary water hammer from occurring.
When pumping plant normally runs the operating mode facing unexpected dead electricity, the water hammer that now pumping plant occurs can produce great collapsing force.While dead electricity, the UPS device of triggers presence controller enters work, and control unit 2 sends instruction to pilot valve, and solenoid valves is opened, and main valve is opened, and the pressure wave that anti-pass is returned is from the release of water hammer prevention valve.In the normal operating mode run, pressure in the pressure transmitter Real-time Feedback pipe network that pipeline is arranged is changed to controller, when occurring pressure oscillation on large scale, and vibration amplitude exceed pressure transmitter setting high level or low value time, controller sends signal immediately to solenoid valve, main valve opens the release manifold pressure that sluices, now generation signal is exported to audible-visual annunciator and is reported to the police by valve event, by installing audible-visual annunciator additional to central control room, pressure surge stops any action of valve in advance and carries out sound alarm and flash of light immediately, make operator can make corresponding reaction immediately in control room, greatly improve the Security of equipment.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any reference character in claim should be considered as the claim involved by limiting.
