Abstract
The utility model discloses a visit pressure measuring device that drains, it includes tee bend and flange, tee bend fixed connection is on the stagnant water sleeve pipe, at tee bend side tip fixed connection flange, the flange outside is connected with the ring flange, and the centre of ring flange is equipped with the inspection hole, and the welding of the inspection hole outside has the nut, is connected with the manometer on the nut. The water stop sleeve for drilling is 4 inch iron pipe with exposed flange and connected to 4 inch valve and 4 inch tee, and the water pressure measuring device is connected to the 4 inch tee. The mine water pressure generally does not exceed 1MPa, so the pressure gauge with the measuring range of 1MPa is selected for use, the water pressure measuring device is simple and practical in design, and after the three-way connection with the water stop sleeve, the water pressure change condition can be actually measured, and a good use effect is obtained.
Description
Technical Field
The utility model relates to a pressure measurement device especially relates to a visit drainage pressure measurement device, belongs to the colliery and visits drainage equipment technical field in the pit.
Background
According to the regulations of the coal mine water control regulations, when underground water exploration and drainage are carried out, the water pressure of a drill hole needs to be detected. The existing drilling water stop sleeve is not provided with a device for measuring water pressure, and how to add a detection structure according to the existing structure is simple in structure and convenient to construct, which is the technical problem facing the prior art.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: a4-inch iron pipe is generally selected as a drilling water stop casing, a flange is exposed out of the casing, a 4-inch valve and a 4-inch tee joint are connected, and the water pressure measuring device needs to be connected with the 4-inch tee joint. The water pressure of the mine is generally not more than 1MPa, so that a pressure gauge with the measuring range of 1MPa is selected, and the existing problems are effectively solved.
The technical scheme of the utility model is that: the utility model provides a visit pressure measuring device that drains, it includes tee bend and flange, tee bend fixed connection is on the sleeve pipe that ends water, at the flange of the lateral end fixed connection of tee bend, the flange outside is connected with the ring flange, and the centre of ring flange is equipped with the inspection hole, and the welding of inspection hole outside has the nut, is connected with the manometer on the nut.
The utility model has the advantages that: compared with the prior art, adopt the technical scheme of the utility model, 4 cun iron pipes are generally selected for use to drilling stagnant water sleeve pipe, expose the flange, connect upper 4 cun valves and 4 cun tee joints, and pressure measuring equipment need be connected with 4 cun tee joints. The mine water pressure generally does not exceed 1MPa, so the pressure gauge with the measuring range of 1MPa is selected for use, the water pressure measuring device is simple and practical in design, and after the three-way connection with the water stop sleeve, the water pressure change condition can be actually measured, and a good use effect is obtained.

fig. 2 is a side view of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Example 1: as shown in attached figures 1-2, the pressure measuring device for water detection and drainage comprises a tee joint 5 and a flange 4, wherein the tee joint 5 is fixedly connected to a water stop sleeve, the side end part of the tee joint 5 is fixedly connected with the flange 4, the outer side of the flange 4 is connected with a flange plate 3, a detection hole 6 is formed in the middle of the flange plate 3, a nut 2 is welded on the outer side of the detection hole 6, and a pressure gauge 1 is connected to the nut 2.
The water stop sleeve for drilling is 4 inch iron pipe with exposed flange and connected to 4 inch valve and 4 inch tee, and the water pressure measuring device is connected to the 4 inch tee. The water pressure of the mine is generally not more than 1MPa, so that a pressure gauge with the measuring range of 1MPa is selected, the water pressure measuring device is simple and practical in design, the change condition of the water pressure can be measured after the water pressure measuring device is connected with the tee joint of the water stop sleeve,
4 inches tee joints are installed on 4 inches stop sleeves on the drainage drill holes, and water pressure measuring devices are installed on side openings of the tee joints to measure the water pressure of the drill holes.
The water stop sleeve for drilling is 4 inch iron pipe with exposed flange and connected to 4 inch valve and 4 inch tee, and the water pressure measuring device is connected to the 4 inch tee. The mine water pressure generally does not exceed 1MPa, so the pressure gauge with the measuring range of 1MPa is selected for use, the water pressure measuring device is simple and practical in design, and after the three-way connection with the water stop sleeve, the water pressure change condition can be actually measured, and a good use effect is obtained.
The parts of the present invention not described in detail are the known techniques of those skilled in the art. Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
