Abstract
The invention provides a pressure hole drain which comprises a water storage tank and a water level meter. The upper and lower ends of the water storage tank are provided with a water inlet and a water outlet respectively. Each of the water inlet and the water outlet is provided with a valve. Two ends of the water level meter are communicated with the upper and lower ends of the water storage tank respectively. The pressure hole drain is simple, reasonable and compact in structure, overcomes the defects in the prior art, and is capable of monitoring water level of the water storage tank in real time to prevent gas pressure loss when used for draining water in a pressure hole.
Description
Technical field
The present invention relates to the technology of discharging water, relate in particular to a kind of pressure tap tailrace.
Background technology
In recent years, for guaranteeing Safety of Coal Mine Production, need constantly improve the collection of gas data in the Coal Production process, for guaranteeing the accurate mensuration of gas pressure, in measuring pressure measurement boring, need to reduce ponding in the pressure tap before the gas pressure as far as possible, weaken ponding to the influence of gas pressure.But in the process of discharging pressure tap ponding, with the ponding emptying, easily cause gas to reveal, so in the discharging pressure tap, during ponding, should keep a spot of technology, prevent that gas from revealing, influence the accurate of gas pressure.
At present, the tailrace that is used for discharging pressure measurement boring in the underground pressure measurement for coal mine process is made up of the water storage box with water inlet and dewatering outlet, though can reach the purpose that discharges water, but the process that discharges water is accurate inadequately, water level in the tailrace is not visible, the normal gas that causes because excessively discharging water is revealed, thereby it is inaccurate to cause gas pressure to be measured.
Summary of the invention
The objective of the invention is to, discharge uncontrollable problem at above-mentioned existing tailrace water level, propose a kind of pressure tap tailrace, when discharging water for pressure tap, can monitor the water level that discharges water in real time, prevent the generation of gas pressure damaed cordition.
For achieving the above object, the technical solution used in the present invention is: a kind of pressure tap tailrace, comprise water storage box and water level meter, described water storage box top and bottom are respectively arranged with water inlet and dewatering outlet, described water inlet and dewatering outlet are respectively arranged with valve, and described water level meter two ends are communicated with the water storage box top and bottom respectively.
Further, described water level is counted transparent conduit.
Further, described water level is counted float gauge.
Further, described water storage box lower end is provided with support.
Further, described valve is ball valve.
Further, described water level meter adopts hermetically-sealed construction with the water storage box place of connection.
Pressure tap tailrace of the present invention is simple and reasonable for structure, compact, the water storage box arranged outside of pressure tap tailrace of the present invention has that be communicated with it and visual water level meter, described water storage box is collected the ponding in the pressure measurement boring, show by described water level meter, and accurately emit by the ball valve of described dewatering outlet.Be that the whole process water level that discharges water is visual, can not cause gas pressure loss, the ponding in the firedamp drainage pressure tap that pressure tap tailrace of the present invention can be convenient, reliable and safe because of ponding emptying.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 described pressure tap tailrace;
Fig. 2 is the structural representation of embodiment 2 described pressure tap tailraces.
The specific embodiment
Fig. 1 is the structural representation of embodiment 1 described pressure tap tailrace.
Present embodiment discloses a kind of pressure tap tailrace for ponding in storage, the firedamp drainage pressure tap, as shown in Figure 1, this pressure tap tailrace, comprise water storage box 4 and water level meter 1, water storage box 4 is columniform, as to have certain accommodation space casing, be appreciated that the needs in order to guarantee to discharge water, this accommodation space should be more than or equal to the pressure tap volume, and present embodiment middle water level meter 1 adopts float gauge.These water storage box 4 top and bottom are respectively arranged with water inlet 2 and dewatering outlet 7, water inlet 2 and dewatering outlet 7 are respectively arranged with ball valve, described water level meter 1 two ends are communicated with water storage box 4 top and bottom respectively, arranging highly of water level meter 1 lower end should not be lower than dewatering outlet 7, and should be as far as possible with dewatering outlet 7 on same horizontal plane.For preventing water level meter 1 with water storage box 4 junction pressure releases or leak that water level meter 1 is communicated with the place with water storage box 4 should adopt hermetically-sealed construction 6, keeps sealing, the sealing structure includes but not limited to gasket seal.Water storage box of the present invention 4 lower ends also are provided with for the fixing support 5 of water storage box 4.
The operating principle of the described pressure tap tailrace of present embodiment: during use, with water inlet 2 by pipeline and pressure tap conducting, open the ball valve of water inlet 2, ponding in the pressure tap flows into water storage box 4 from pipeline, water inlet 2 under gas pressure or ponding self pressure, the water level of ponding 3 constantly rises in the water storage box 4, according to law of connected vessels, the water level that the water level meter 1 that is communicated with water storage box 4 manifests is water level in the water storage box 4.When water level reach a certain height in the water storage box 4, the ball valve of opening dewatering outlet 7 discharged water, and the water level in the water storage box 4 constantly descends, this downward trend manifests at water level meter 1, when the water level that manifests on the water level meter 1 is about to emptying, close the ball valve of dewatering outlet 7, end discharges water.Be appreciated that the open and close of water inlet 2 and dewatering outlet 7 valves, can be by implementing with the watch-dog of its Electricity Federation, also can be by artificial embodiment.
The pressure tap tailrace of above embodiment can show the water level of ponding 3 in the water storage box 4 intuitively by water level meter 1, and when effectively having avoided discharging water, the loss of gas pressure is accomplished accurately to discharge water.
Fig. 2 is the structural representation of embodiment 2 described pressure tap tailraces.
It is substantially the same manner as Example 1 that present embodiment discloses a kind of pressure tap tailrace, and the water level meter 1 of present embodiment employing is one section transparent hose as different from Example 1, and concrete structure as shown in Figure 2.Transparent hose in the present embodiment and water storage box 4 form linker, can judge the water level of ponding 3 in the water storage box 4 by the height of water level of ponding in the observation transparent hose.
The present invention is not limited to the described pressure tap tailrace of above-described embodiment, and the change of water level meter kind, the change of water storage box structure are all within protection scope of the present invention.
It should be noted that at last: above each embodiment is not intended to limit only in order to technical scheme of the present invention to be described; Although the present invention has been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of various embodiments of the present invention technical scheme.
