Working procedure of the present utility model is as follows:
For example, in filling process, the parameter matching between grouting flow and grouting pressure is as follows:
Grouting flow and grouting pressure matching list:
As depicted in figs. 1 and 2, before grouting work starts, the import 1-2 of throttle valve 1 is connected with the return pipe of grouting pipeline, the outlet 1-3 of throttle valve 1 is connected with overfall groove, then corresponding control parameter is inputted by parameter, display circuit 11-6 input, for example control parameter, as pressure (: controlled grouting pressure P=3Mpa) that grouting restriction is controlled, meet grouting and finish uninterrupted (for example: when flow <1L/S), meet the grouting time (for example: 30 minutes) of Grouting Design, grouting dangerous pressure (for example: grouting dangerous pressure PW=4Mpa).
Start the utility model, the host scm 11-1 output control signal of electrical-controller 11 is to motor-drive circuit 11-7, thereby motor-drive circuit 11-7 control drive motor 10 reverses and drives leading screw 7 to rotate, because leading screw 7 and nut 6 form lead screw pair, leading screw 7 drives stopper rod 4 to exit to guide holder 3 Way ins, in the time that first tinsel 14 on the protruding 4-1 left side and first triggers tinsel 13 and contacts, electrical-controller 11 is controlled drive motor 10 and is stopped reversion, and now throttle valve 1 is in full open mode.In filling process, host scm 11-1 receives pipeline grouting pressure signal and grouting flux signal by signal input circuit 11-5, process and judge, control drive motor 10 forward or reverse by motor-drive circuit 11-7, thereby control throttle valve 1 folding size, make grouting pressure and grouting flow meet all the time coupling requirement.In the time that second tinsel 16 on protruding 4-1 the right contacts with the second triggering tinsel 15, electrical-controller 11 is controlled motor and is stopped forward, and now throttle valve 1 is in minimum on state.Like this, received in real time grouting flow and pressure signal and judged by electrical-controller 11, control stopper rod 4 pushes the outer wall of spring tube, makes spring tube 1-4 that resiliently deformable occur, change the passage section area of spring tube 1-4, realize the match control to grouting rate-of flow, pressure.Under electrical-controller 11, the first triggering tinsel 13, the second triggering tinsel 15, the first tinsel 14 and the second tinsel 16 actings in conjunction, the first tinsel 14 and the second tinsel 16 are moved all the time and trigger between tinsel 15 at the first triggering tinsel 13 and second, control throttle valve 1 folding size guarantee within safety range thereby make stopper rod 4 push spring tube 1-4.
If pressure progressively raises in filling process, for example, in the time that the grouting pressure of pipeline has just reached predefined pilot pressure (: 3Mpa), host scm 11-1 controls drive motor 10 according to pressure signal by motor-drive circuit 11-7 and turns, thereby drive stopper rod 4 to exit to the Way in of guide holder 3, in this process, throttle valve 1 is progressively opened, make the pressure drop of pipeline, for example, in the time dropping to programmed values (2.9Mpa), host scm 11-1 controls drive motor 10 forwards by motor-drive circuit 11-7 again, promoting stopper rod 4 advances to the Way out of guide holder 3, pushing spring tube 1-4, the face that dams of spring tube 1-4 is diminished gradually, thereby make to reduce by the grouting slurry flow of throttle valve 1, the pressure of pipeline is progressively raise, for example, in the time being elevated to programmed values (: 3.1Mpa), host scm 11-1 controls drive motor 10 by motor-drive circuit 11-7 again and reverses, so repeatedly, when loine pressure raises, host scm 11-1 controls drive motor 10 by motor-drive circuit 11-7 and reverses, throttle valve 1 is progressively opened, when loine pressure reduces, host scm 11-1 controls drive motor 10 forwards by motor-drive circuit 11-7, make throttle valve 1 progressively reduce the face that dams of spring tube 1-4, thereby within pressure being controlled to the scope of setting.
For example, when grouting flow condition while reaching termination condition when flow <1L/S (), host scm 11-1 enters predefined end time countdown (for example: 30 minutes) according to pressure, flux signal, if pressure condition and flow condition all meet and reach the condition of end (grouting pressure is controlled at 3Mpa in this control procedure always, flow <1L/S simultaneously), while finishing countdown termination, host scm 11-1 quits work automatically, and sends grouting end signal by warning circuit 11-8.For example, if pressure condition or flow condition do not reach suddenly and finish to require (grouting pressure <3Mpa or flow >1L/S) in countdown process, host scm 11-1 automatically removes and finishes countdown state, rejudge pressure condition and flow condition, in the time that pressure condition and flow condition meet again, re-start end countdown.
The circuit hardware of electrical-controller 11 of the present utility model adopts Isolation, grounding technology, avoids external interference, and internal electric source has been taked the measures such as shielding, voltage stabilizing, protection, ensures power supply quality.For adapting to the rugged environment of working site, the utility model adopts and seals, prevents dust, the casing packaging structure of antidetonation.By above measure, ensured the utility model can be in rugged environment reliably working.
The utility model is provided with grouting pressure safety protection; protection part is independently protected single-chip microcomputer 11-2 monitoring grouting loine pressure by another; for example, when host scm 11-1 occurs malfunction and while making loine pressure reach dangerous pressure (: loine pressure has reached 4MPa) in when work; protection single-chip microcomputer 11-2 stops immediately the work of host scm 11-1 and sends warning; rotate and open throttle valve 1, the grouting pressure of clearing by motor-drive circuit 11-7 control drive motor 10.
