The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
a kind of supply channel pressure limit pressure release atomization mechanism, as shown in Figure 1, comprise feed pipe 6, be connected with main valve 1 and non retern valve 5 on feed pipe 6, the airtight pressure meter 2 that is communicated with also on feed pipe 6, pressure regulator valve 3, manually-operated gate 4 and relief valve 10, the airtight pressure release fog-spray nozzle 9 that is communicated with of relief valve 10, pressure meter 2, pressure regulator valve 3, manually-operated gate 4 and relief valve 10 are between main valve 1 and non retern valve 5, feed pipe 6 also is connected with filling pipe 7, filling pipe 7 is airtight the communicating of feed pipe 6 of an end and main valve 1 inboard wherein, airtight the communicating of feed pipe 6 in filling pipe 7 other ends and non retern valve 5 outsides, be connected with water compensating valve 11 on filling pipe 7.In the present embodiment, non retern valve 5 is connected with feed pipe 6 by flange 8; Feed pipe 6 and filling pipe 7 outsides are connected with card hurdle 12.
Embodiment recited above is described the preferred embodiment of the present invention; be not that the spirit and scope of the present invention are limited; under the prerequisite that does not break away from design concept of the present invention; various modification and improvement that in this area, common engineers and technicians make technical scheme of the present invention; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
there is Yuan's hall well water supply well at Caili coal mine main dustproof water source in the applicant place, three main water sources such as Sewage Disposal and western wing drain sump (also being western sump), three water sources are parallel way of supplying water, and the main stope of Caili coal mine is distributed in down-hole two levels (minimum absolute altitude-490) at present, be up to 5.6MPa according to dustproof supply channel hydraulic pressure under drop manhole, and according to Caili coal mine knowhow for many years, when down-hole hydraulic pressure reaches 3.8---4.2 MPa, can satisfy Production requirement, meet again Caili coal mine because of the low reality of the aging bearing capacity of pipeline, therefore installed supply channel pressure limit pressure release atomization mechanism after deliberation in main-supply road, place, one number service road, large lane, south, down-hole, to the main-supply road carrying out pressure regulation, pressure release, to guarantee pressure stability, reduce the appearance of evaporating, emitting, dripping or leaking of liquid or gas phenomenon.
The present invention a kind ofly can regulate the dustproof pressure of supply water of mine automatically, the pipeline bearing capacity that minimizing causes because pipeline is aging is low, often occurring during hypertonia metals run out affects the generation of production accident, realizes the device of supply channel pressure limit automatic Regulation, pressure release.
The phenomenon that occurs metalling run out when solving the dustproof supply channel hypertonia in down-hole is effectively carried out pressure release, voltage stabilizing to supply channel, the assure feed water system stability, the applicant's design and installation supply channel pressure limit pressure release atomization mechanism.This atomization mechanism is contacted Yuan's hall well water source, down-hole and sump gravity flow water source, level west, the junction uses Ka Lan, flange, main valve, water compensating valve, pressure regulator valve, non retern valve to separate, simultaneously separately lay one tunnel 4 writing brush road (being filling pipe) in parallel with the Regulation Control device, form the double loop.Wherein the western sump in a level-110 plays the effect of water storage, pressure release, when two horizontal supply channel maintenance pressure surpass the setting pressure 4.2MPa of pressure regulator valve, after pressure regulator valve reduces pressure to two horizontal supply channel pressure, part water stores by the anti-western sump in a level-110 that feeds to of pipeline, another part water enters two total returning tunnel purifications of spraying, the purpose of realization to the supply channel pressure release by the pressure release atomization mechanism; Many when the water place, water supply volume is large, during the dustproof pipeline hydraulic pressure water shortage of two levels, open 4 cun water compensating valves, the water of the western sump of a level carries out the water yield to two levels and replenishes, thereby play the purpose that one or two horizontal dust-proof waters replenish mutually, realize all pressures voltage stabilizing of mine water.(water (flow) direction when in Fig. 1, direction shown in filled arrows is pressure limit, the water (flow) direction when direction shown in hollow arrow is insufficient pressure)
After installing the present invention, the problem that when not only having solved the supply channel hypertonia, pipeline is often metalled run out has guaranteed the stable of dustproof water system, and realizes unloading water recycling, reduces to greatest extent water resource waste, reaches the purpose of energy-saving and emission-reduction.After using, can reduce per month in this device the dust-proof water input amount that causes because of the water system shakiness more than 3000m3, the evaporating, emitting, dripping or leaking of liquid or gas phenomenon reduces more than 60%, greatly improve underground mine water supply Systems balanth and safety in production assurance coefficient, also greatly reduced maintenance personal's labour intensity simultaneously.
