In power transient process, air valve capacity changes with inner pipe water pressure, timely and effectively water hammer can be inhibited to endanger.In air valve
On the basis of, increase controllable valve and pressure sensor, form air valve protecting water hammer device, structure is simple；Controllable valve is opened
It spends the pipeline pressure data measured with pressure sensor and changes, i.e., pipeline pressure is different, and extraction flow is different, protecting water hammer effect
Fruit is good.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of air valve protecting water hammer device of the utility model.
In figure, 1. air valves, 2. controllable valves, 3. controllers, 4. pressure sensors, 5. aqueducts.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of air valve protecting water hammer device of the utility model, as shown in Figure 1, including air valve 1, air valve 1 passes through
Branch pipe connects aqueduct 5, one end of the affixed branch pipe of air valve 1, and the other end of branch pipe is fixed on the side wall of aqueduct 5,
Controllable valve 2, also affixed controller 3 and pressure sensor 4 on branch pipe are installed in the middle part of branch pipe.
The axis of branch pipe is vertical with the axis of aqueduct 5.
Pressure sensor 4 and the equal data connection controller 3 of controllable valve 2, controller 3 are measured according to pressure sensor 4
Real time data controls the aperture of controllable valve 2, thus air inlet/extraction flow of control air valve 1.
Controller 3 and pressure sensor 4 are fixed on the side wall of affixed 5 one end of aqueduct of branch pipe.
The local high spot in aqueduct 5 is arranged in along hydraulic pipeline for air valve 1.
A kind of air valve protecting water hammer device working principle of the utility model is that controllable valve 2 is according to pressure sensor 4
The real time data measured should mutually have different apertures, i.e., different extraction flows, and the water-supply-pipe of hydraulic pipeline is arranged in air valve 1
Local high spot in road 5, in exhaust process, the real time data difference that pressure sensor 4 measures will cause 2 aperture of controllable valve
Difference, and then air valve 1 has different extraction flows, i.e., in exhaust process, extraction flow changes with inner pipe water pressure, therefore
Protect the effect of water hammer more preferable, the aperture of controllable valve 2 measures between real time data with pressure sensor 4 corresponding pass
System, it is different according to Practical Project situation, using program can be calculated controllable valve aperture and pressure sensor data measured it
Between relationship.
A kind of air valve protecting water hammer device course of work of the utility model is as follows: in Calculations of Hydraulic Transient, working as water pump
When losing transmission or termination of pumping, pump rotary speed decline, flow reduces, when N point pressure is less than the operating pressure when point operates normally,
Controllable valve 2 fully opens, and rapid a large amount of air inlets avoid the generation of negative pressure.When pipeline pressure rises, N point pressure is greater than the point
When normal operation when operating pressure, each moment, controllable valve 2 should mutually have not according to the real time data that pressure sensor 4 measures
With aperture, gas in discharge pipe, extraction flow is variate, it can according to the variation of manifold pressure, reasonable control is empty
The capacity of air valve 1 protects the effect of water hammer more preferable.
A kind of air valve of air valve protecting water hammer device selection of the utility model is a kind of for preventing negative pressure
Special valve, it is installed in the eminence (high spot) of pipeline, empty when the overpressure at air valve falls below atmospheric pressure
Air valve is opened, and air is allowed to enter, will not negative pressure it is excessive and make water column separation；When overpressure is greater than atmospheric pressure at air valve,
Allow air to be discharged, but do not allow liquid to be discharged, therefore can prevent water hammer due to cavities collapsing caused by negative pressure from endangering.Air valve
The necessaries of pipeline air exhaust water, when vacant duct water-filling, exclude inner air tube in time when being blank pipe starting, avoid generating vapour lock and drawing
Send out pump start water hammer.In addition, air valve also ensures the unobstructed of sluicing when water-carriage system is cut off the water and overhauled.With air tank and pressure regulation
Other protecting water hammer measures such as tower are compared, and air valve has many advantages, such as simple structure, with low investment, easy for installation.It is pressed by setting
Real time data difference control 2 aperture of controllable valve that force snesor 4 measures is different, and then air valve 1 has different exhaust streams
Amount, i.e., in exhaust process, extraction flow changes with inner pipe water pressure, and the effect of protection water hammer can be improved.
