Description
Technical field
The present invention relates to explosion-proof valve technical field, particularly relate to a kind of safety device based on explosion-proof valve.
Background technology
At present, along with the fast development of society, water increases day by day as a kind of important living material, its consumption, mesh
Before, hydraulic pipeline is one of important means realizing water delivery process, but in the middle of actual use, the hydraulic pressure meeting in water-supply-pipe
Occurring to increase or reduce, such as when certain branch road of upstream is closed, the hydraulic pressure on main line will increase, work as hydraulic pipeline
When rupturing, then the hydraulic pressure in hydraulic pipeline can reduce, if these hydraulic pressure are in a rational range intervals, the most not
Pipeline can be caused any destruction, but once hydraulic pressure is beyond threshold range, then hydraulic pipeline can be caused serious injury or
Person causes user cannot obtain water source.Therefore, design and develop and a kind of according to the hydraulic pressure of current and then current can be controlled
Safety device based on explosion-proof valve seem it is particularly important.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of safety device based on explosion-proof valve, should be based on explosion-proof valve
Safety device can carry out security control to the hydraulic pressure in aqueduct, when the hydraulic pressure in hydraulic pipeline increases or reduces
Time, this explosion-proof valve all can start, and then hydraulic pipeline is carried out safeguard protection.
The present invention solves that technical problem is adopted the technical scheme that present in known technology:
A kind of safety device based on explosion-proof valve, at least includes:
The explosion-proof valve being installed in hydraulic pipeline and three-way valve (1)；First valve port of described three-way valve (1), the second valve port
It is connected with hydraulic pipeline respectively；3rd valve port of described three-way valve (1) is turned on backflow storehouse (4) by diversion pipeline；Described
It is provided with electromagnetic valve (2) at 3rd valve port of three-way valve (1)；Pressure transducer (3) it is provided with in described hydraulic pipeline；Described
The signal output terminal of pressure transducer (3) is defeated with two of logic or circuit by the first comparator and the second comparator respectively
Entering terminal electrical connection, the lead-out terminal of described logic or circuit electrically connects with the control terminal of electromagnetic valve (2)；Described first compares
The reference terminal of device is the lower threshold input terminal of hydraulic pressure, the upper limit threshold that reference terminal is hydraulic pressure of described second comparator
Input terminal.
As preferably, the present invention additionally uses following technical scheme:
Further: described pressure transducer (3) has M, and M pressure transducer is equally distributed in the difference of hydraulic pipeline
Position, M is the natural number more than 2.
The present invention has the advantage that with good effect:
By using technique scheme, hydraulic pressure can be detected by pressure transducer in hydraulic pipeline in real time, and
Testing result is sent to comparator, subsequently testing result is compared respectively with upper limit threshold and lower threshold, if water
Pressure beyond threshold range, then controls electromagnetic valve and opens, and then current import backflow storehouse, prevent the waste of water.Work as hydraulic pipeline
In when there is multiple pressure transducer, it is also possible to deduce, by the detection of signal, the region that circuit failure occurs.
Accompanying drawing explanation
Fig. 1 is the use state diagram of the preferred embodiment of the present invention；
Fig. 2 is the circuit diagram of the preferred embodiment of the present invention.
Wherein: 1, three-way valve；2, electromagnetic valve；3, pressure transducer；4, backflow storehouse.
Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing
Describe in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of safety device based on explosion-proof valve, including:
The explosion-proof valve being installed in hydraulic pipeline and three-way valve 1；First valve port of described three-way valve 1, the second valve port are respectively
It is connected with hydraulic pipeline；3rd valve port of described three-way valve 1 is turned on backflow storehouse 4 by diversion pipeline；At described three-way valve 1
It is provided with electromagnetic valve 2 at 3rd valve port；Pressure transducer 3 it is provided with in described hydraulic pipeline；The letter of described pressure transducer 3
Number lead-out terminal is electrically connected with two input terminals of logic or circuit by the first comparator and the second comparator respectively, described
The lead-out terminal of logic or circuit electrically connects with the control terminal of electromagnetic valve 2；The reference terminal of described first comparator is hydraulic pressure
Lower threshold input terminal, the input terminal of the upper limit threshold that reference terminal is hydraulic pressure of described second comparator.
The operation principle of this preferred embodiment is: three-way valve 1 He, when the hydraulic pressure in hydraulic pipeline excessive or too small time, then
At least a comparator exports one and triggers signal, by triggering signal being sent to electromagnetic valve 2, electromagnetism after logic or computing
Valve 2 is opened after receiving signal, and then realizes sluicing, and guides current to backflow storehouse 4, prevents the waste of current.
As preferably, on the basis of above preferred embodiment:
Further: described pressure transducer 3 has M, and M pressure transducer is equally distributed in the not coordination of hydraulic pipeline
Putting, M is the natural number more than 2.
Above embodiments of the invention are described in detail, but described content have been only presently preferred embodiments of the present invention,
It is not to be regarded as the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement etc.,
Within all should still belonging to the patent covering scope of the present invention.
