The concrete meaning of language in the present invention.
As shown in Figs. 1-3, it is a kind of geothermal well backflow device provided in this embodiment, including recharge pipeline 3,4 and of floating ball
Drag-line 2.
Recharge pipeline 3 is equipped with regulating valve 1；Floating ball 4 floats on the water surface in inverted well 6；Positioned at below time of the water surface
The lateral wall for filling pipeline 3 is equipped with fixed guide rail 5；The first end of drag-line 2 is connect with floating ball 4, and the second end of drag-line 2, which passes through, fixes
Guide rail 5, and connect with the adjusting spool of regulating valve 1 11, control to adjust the aperture of valve 1.
Further, regulating valve 1 is set at the well head of inverted well 6.
Further, 2 outside of drag-line is equipped with protection support frame.Further, it is located at 2 outside of drag-line in inverted well 6
Equipped with protecting tube 16.In the present embodiment, drag-line 2 is stainless steel cable wire.
Further, floating ball 4 is slim-lined construction.In the present embodiment, floating ball 4 is made of stainless steel.
Further, fixed guide rail 5 is fixedly connected by supporting rack with the lateral wall of recharge pipeline 3.In the present embodiment, Gu
Determine the conduit that guide rail 5 is vertically arranged；And conduit is stainless-steel pipe.
Below by specific process, further details of explanation.
The pressure of recharge pump startup on recharge pipeline 3, the water inlet 13 of regulating valve 1 increases, and is more than the water outlet of regulating valve 1
8 pressure of mouth, supervisor's valve 9 of regulating valve 1 are opened under pressure, start recharge.
Floating ball 4 is swum in always on the water surface of inverted well 6.When the water surface of inverted well 6 goes up, floating ball 4 also and then rises.
Floating ball 4, which rises, drives drag-line 2 to rise adjusting spool 11 and adjustment hole plug 14, and adjustment hole is opened.With the aperture of adjustment hole
Increase, the flow into adjusting cavity 10 increases, when the flow of inlet water in adjusting cavity 10 is more than from what adjusting return port 12 flowed out
When water flow, pressure increases in adjusting cavity 10.As pressure increases in adjusting cavity 10, under the action of holddown spring 7, main pipe valve
The aperture of door 9 reduces, and recharge flow reduces.If floating ball 4 also continues to rise, and in the effect of pressure when rising to certain position
Lower supervisor's valve 9 can be closed thoroughly, and the water level in inverted well 6 stops rising.
The water level of inverted well 6 declines under the effect of gravity, and floating ball 4 also declines with the water surface.Similarly, floating ball 4, which declines, just drives
Steel cable loosens, and adjusting spool 11 slowly declines under the action of spool compression spring 15, and adjustment hole plug 14 reduces opening for adjustment hole
Degree.Flow into adjusting cavity 10 reduces, and pressure reduces in adjusting cavity 10, and holddown spring 7 compresses, and supervisor's valve 9 is slowly opened,
Recharge flow increases.When floating ball 4 drops to certain position, supervisor's valve 9 is thoroughly opened, and recharge flow reaches maximum at this time,
It so moves in circles and reaches the dynamic equilibrium of a recharge water level, the opposite of liquid level is maintained during geothermal reinjection well recharge
Stablize.
The present embodiment provides a kind of geothermal well backflow devices, on the one hand, is adjusted back by the SEA LEVEL VARIATION in inverted well
The size of perfusion flow makes the water surface in inverted well keep a metastable water level, realizes the stability contorting of recharge water level.
On the other hand, it is not necessarily to additional power source and sensor, drag-line is pulled with the SEA LEVEL VARIATION of inverted well by floating ball, and be transmitted to adjusting
The adjusting spool of valve adjusts recharge water to control to adjust the aperture of valve, and stable, control is timely, at low cost.Separately
Outside, by being adjusted to regulating valve, the adjusting to water-level fluctuation size is realized, flexibly and easily.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
