Description
Technical field
the present invention relates to the control method that a kind of emptying underground filling founds inner air tube, particularly relate to a kind of control method adopting the emptying underground filling of shutoff valve to found inner air tube, belong to mining filling technique field.
Background technology
at present, because the exploitation under some specific conditions can bring very serious impact to surface buildings, highway, dam etc., therefore underground filling more and more comes into one's own, and paste body filling mode is because intensity after filling is high, down-hole is not easy the advantages such as dehydration and is widely used, but the material that paste body filling mode is carried is heterogeneous body, easily produce gas at pipeline riser place and cause plugging, once plugging will cause tremendous influence to whole filling system, therefore, the operation of air to whole filling system at emptying standpipe place is significant.
therefore, along with improving constantly of filling in mine technology, timely emptying underground filling founds inner air tube to ensure the operation conditions of filling pipeline, finds and handling failure point, has become the task of top priority of filling in mine System Development from now on.
Summary of the invention
object of the present invention is just to overcome prior art above shortcomings, provides a kind of control method adopting the emptying underground filling of shutoff valve to found inner air tube.The present invention adopts hydraulic control throttle valve, the having stable behavior of valve; The size of valve opening can be measured accurately by displacement transducer; Can the concrete aperture of control valve accurately by PLC control system.
the technical solution adopted in the present invention is: the emptying underground filling of this employing shutoff valve founds the control method of inner air tube, include hydraulic power unit, shutoff valve, displacement transducer, PLC control system, be characterized in PLC control system by control cables respectively with hydraulic power unit, shutoff valve is connected, hydraulic power unit is connected with shutoff valve by oil pipe, being placed in the displacement transducer on shutoff valve is delivered in PLC control system by the analog module of PLC by real time value, PLC control system controls the size of shutoff valve aperture according to the real time value that displacement transducer transmits, emptying underground filling founds inner air tube.
for completing object of the present invention better, the size of described control shutoff valve aperture, founding inner air tube with emptying underground filling is: first rinse underground filling pipeline with water, in the process of rinsing, shutoff valve aperture is transferred to maximum, then to pump cement slurry in pipeline, pipeline is lubricated, again to pipeline pumping material after lubrication, before pumping material, shutoff valve is adjusted to low discharge, flow after making the flow before shutoff valve be greater than shutoff valve, so that make the material in pipeline slowly be full of underground filling standpipe, the outlet valve that air in pipeline is arranged from underground filling standpipe is discharged.
compared with prior art, the invention has the beneficial effects as follows: adopt hydraulic control throttle valve, the having stable behavior of shutoff valve; The size of shutoff valve aperture can be measured accurately by displacement transducer; The concrete aperture of shutoff valve can be controlled accurately by PLC control system.
Accompanying drawing explanation
fig. 1 is control system of the present invention composition schematic diagram.
fig. 2 is the schematic layout pattern of shutoff valve of the present invention.
fig. 3 is control flow schematic diagram of the present invention.
Detailed description of the invention
below in conjunction with drawings and Examples, the present invention is further described.
embodiment 1.
as shown in FIG. 1 to 3, the emptying underground filling of this employing shutoff valve founds the control method of inner air tube, include hydraulic power unit, shutoff valve, displacement transducer, PLC control system, wherein PLC control system by control cables respectively with hydraulic power unit, shutoff valve is connected, hydraulic power unit is connected with shutoff valve by oil pipe, real time value is delivered in PLC control system by PLC analog module by the displacement transducer be placed on shutoff valve, PLC control system controls the size of shutoff valve aperture according to the real time value that displacement transducer transmits, emptying underground filling founds inner air tube.
implementation step is as follows.
set up control system by accompanying drawing 1, the valve position illustrated by accompanying drawing 2 carries out layout, and the control flow illustrated by accompanying drawing 3 controls.
start hydraulic power unit by PLC control system, the self-sustaining that hydraulic power unit itself can carry out pressure controls, for shutoff valve (2) regulates aperture ready.First stowing operation rinses pipeline with water, in the process of rinsing, shutoff valve (2) aperture is transferred to maximum, then to pump cement slurry in pipeline, pipeline is lubricated, just can to pipeline pumping material after lubrication, before pumping material, shutoff valve (2) is adjusted to low discharge, flow after making the front flow of shutoff valve (2) be greater than shutoff valve (2), material in such pipeline slowly will be full of standpipe, and air will be discharged from the outlet valve (1) above standpipe.
detailed process is: first shutoff valve (2) can be adjusted to 1/3 or 1/2 open position according to concrete rate of pumping, open outlet valve (1), start pumping, whether observe outlet valve (1) has material to flow out, if there is material to flow out, shutoff valve (3) is adjusted to maximum opening, whether have material flow out, if now still had, prove that vertical inner air tube is emptying if observing outlet valve (1).Now keep shutoff valve (2) aperture constant, outlet valve (1) is closed.The requirement of filling process can be met in addition according to the aperture of the size adjustment shutoff valve (2) of pump output in the process of carrying out pipeline pack.
Claims (1)
1. the control method adopting the emptying underground filling of shutoff valve to found inner air tube, include hydraulic power unit, shutoff valve, displacement transducer, PLC control system, it is characterized in that PLC control system by control cables respectively with hydraulic power unit, shutoff valve is connected, hydraulic power unit is connected with shutoff valve by oil pipe, real time value is delivered in PLC control system by analog module by the displacement transducer be placed on shutoff valve, PLC control system controls the aperture of shutoff valve according to the real time value that displacement transducer transmits, emptying underground filling founds inner air tube, the step that the aperture of described control shutoff valve founds inner air tube with emptying underground filling is: first rinse underground filling pipeline with water, in the process of rinsing, shutoff valve aperture is transferred to maximum, then to pump cement slurry in pipeline, pipeline is lubricated, again to pipeline pumping material after lubrication, before pumping material, shutoff valve is adjusted to low discharge, flow after making the flow before shutoff valve be greater than shutoff valve, so that make the material in pipeline slowly be full of underground filling standpipe, the outlet valve that air in pipeline is arranged from underground filling standpipe is discharged.
