Abstract

The utility model provides a kind of " sleeve pipe-air bag-mucus sealing of hole " new device measuring gas pressure, belongs to mining instrument field gas pressure direction of measurement.Main body is by a thin metal floral tube and to be nested in outside it and the high-pressure gasbag at two ends added by a crude metal floral tube that can slide along interior pipe and some other assembly is formed.During use, hole packer is sent into sealing of hole section, be then inwardly screwed into nut and tighten up outer tube, thus squeezing bushing two ends air bag makes air bag radially expand and compress hole wall.Then mucus is compressed into pipe, and then mucus enters whole sealing of hole section formation hydraulic seal section through the hole on inside and outside floral tube, completes sealing of hole.Sliceable between single-unit sleeve pipe, the single-unit sleeve pipe by splicing varying number meets the requirement of different length sealing of hole distance, thus it is far away to make this utility model have sealed borehole length, the advantages such as spacing is adjustable, is applicable to long distance gas pressure measurement aspect.

Description

A kind of " sleeve pipe-air bag-mucus sealing of hole " new device measuring gas pressure
Technical field
Basis is practical relates to a kind of mining apparatus, gas pressure direction of measurement.
Background technology
Tradition gas pressure measurement device adopts hose construction to connect, and has that sealed borehole length is short, not easily reusable shortcoming and cannot meet gas pressure measurement demand in long distance situation.
Summary of the invention
The technical problems to be solved in the utility model is: effectively cannot solve long sealing of hole and survey gas pressure in order to overcome existing gas pressure measurement device and measure that this is not enough, the utility model, according to producing actual needs, provides a kind of " sleeve pipe-air bag-mucus sealing of hole " novel gas pressure measurement device.It is far away that it has sealed borehole length, spacing is adjustable, strong adaptability, easily reuse, the feature such as simple to operate.
The utility model solves the technical scheme that its technical problem adopts: this utility model adopts hard tube anatomical connectivity, primarily of a thin metal floral tube and to be nested in outside it and the high-pressure gasbag at two ends added by a crude metal floral tube that can slide along interior pipe and some other assembly is formed.Sleeve pipe length can be realized by the single-unit sleeve pipe splicing varying number according to sealing of hole distance length.During use, hole packer is sent into sealing of hole section, be then inwardly screwed into nut and tighten up outer tube, thus squeezing bushing two ends air bag makes air bag radially expand and compress hole wall.Then mucus is compressed into pipe, and then mucus enters whole sealing of hole section formation hydraulic seal section through the hole on inside and outside floral tube, completes long distance sealing of hole.
The beneficial effects of the utility model are: sleeve pipe length can be realized by the single-unit sleeve pipe splicing varying number according to sealing of hole distance length, can meet the demand of long distance sealing of hole pressure measurement, and have strong adaptability, device easily reclaims, reusable, advantage simple to operate.

Detailed description of the invention
In FIG, illustrate the structure of the metal floral tube adopted in the utility model, namely it is the metal tube that a surface is covered with eyelet, and screw thread is carved with to facilitate docking in medial and lateral, floral tube two ends.
In fig. 2, the structure of interior pipe joint is illustrated.
In figure 3, illustrate adjacent inner tube docking operation, namely achieved a butt joint by the helicitic texture be engraved on connectivity port.
In embodiment illustrated in fig. 4, first assembled device, when carrying out interior pipe 3 splicing assembling, first needing according to sealing of hole distance the quantity determining the single-unit sleeve pipe needing splicing, then splicing section by section.Because pipe 3 interior in the course of work will bear pulling force, therefore pipe need link together securely in all single-units, two splicings saving interior pipe are that the screwed pipe by being engraved in interior pipe two ends is screwed into connection, and outer tube 4 operationally bears is screwed into from nut and the extruding force produced, so do not need single-unit outer tube used firmly to connect together, as long as ensure that adjacent single-unit outer tube contacts, all single-unit outer tubes needed to be nested in successively in connecting on pipe 3.In succession floral tube 8 in one end of the pressure measuring chamber 2 that piezometer tube 7 puts in boring 1, so that 2 gas can enter piezometer tube more smoothly in pressure measuring chamber, the other end of piezometer tube 7 stretches out boring 1, and port is ined succession a threeway 13, threeway 13 is connected with gas pressure table 12.After device has been assembled, hole packer is sent into boring 1, prepare sealing of hole operation.
In embodiment illustrated in fig. 5, be carved with screw thread place 9 at interior pipe 3 and be inwardly screwed into nut 10, in the process that nut is screwed into toward the inside, packing ring 11 together can move inward along with nut 10, the part that interior pipe 3 is between front end high air bag 5 and rear end high-pressure gasbag 6 is received short, will together with outer tube 4 slowly by high-pressure gasbag 5 and 6 clamp, compression, until air bag 5 and 6 by compression-expansion to can firmly be stuck in boring 1 hole wall on.Open mucus tank 15, high pressure mucus is passed into the inside pipe of handlance 14, because interior pipe 3 and outer tube 4 are all floral tubes, mucus in interior pipe 3 is entered into the space between the hole wall of outer tube 4 and boring 1 at once by the cellular aperture on interior pipe 3, until the whole space be between high-pressure gasbag 5 and 6 is all full of by mucus, form mucus seal section.And the pressure outline of mucus is higher than the gas pressure estimated.The effect of filling mucus allows mucus be pressed into the space between air bag and hole wall and the fine cracks in hole wall, affects final measurement, complete sealing of hole to prevent the gas in pressure measuring chamber from running away along these holes.Gas in coal and rock beds will naturally osmotic in pressure measuring chamber 2, then enter floral tube 8, then arrive gas pressure table 12 place by piezometer tube 7, then gas pressure table 12 can demonstrate gas force value in pressure measuring chamber.As pressure measurement speed need be accelerated, the valve in threeway 13 can be opened, in pressure measuring chamber 2, be filled with a certain amount of nitrogen by threeway 13 and piezometer tube 7, if gas pressure value does not change for continuous 24 hours, then this stable force value is exactly the gas pressure value in tested coal seam.
