Description
Technical field
The present invention relates to a kind of package seal checker, particularly about a kind of sealing experimental provision of determination of coal seam gas pressure.
Background technology
Determination of coal seam gas pressure is a basic work of pre-preventing coal mine gas disaster.Present gas pressure is measured can be divided into two classes by sealing material, and a class is the solid sealing of hole, and another kind of is the liquid sealing of hole.The used material of solid sealing of hole is clay, grout, polyurethane, high-water material etc., and this class material is owing to the shut-off capacity that lacks microfissure around the pressure measurement boring, thereby sealing of hole is not tight, and the pressure measurement time is longer, and the measurement result error is bigger.The liquid sealing of hole adopts two sections expansion of solids capsules at one section pressure fluid of intermediate seal, relies on the indoor methane gas of this section pressure fluid sealing pressure measurement boring gas.Because liquid has seamless characteristic of not boring under pressure, thus strong to the shut-off capacity of microfissure around the pressure measurement boring, sealing of hole is effective, and the measurement result accuracy is higher.
Therefore, coal-bed gas pressure be can accurately be measured to, the expansion capsule of continuous detecting liquid hole sealing device and the sealing effectiveness of sealing liquid just needed in order to make liquid sealing device.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of experimental provision that detects expansion capsule and sealing liquid sealing property.
For achieving the above object, the present invention takes following technical scheme: a kind of experimental provision that detects expansion capsule and sealing liquid sealing property, it is characterized in that: it comprises a steel pipe, one end of described steel pipe is by the seal plug shutoff, the other end is open, wears a high-pressure delivery pipe on the described seal plug, and high-pressure delivery pipe is communicated to an expanding foam solution container, described expanding foam solution container is communicated to high-pressure air source by another high-pressure delivery pipe, is provided with stop valve on the described two high pressure delivery pipes; Be built-in with the expansion capsule in the open end of described steel pipe, described expansion capsule is communicated to hydraulic pump by a high-pressure delivery pipe, is folded with at least one steel wire and is used for simulation boring slit between described expansion capsule and steel pipe; On one section described steel pipe between described expansion capsule and the seal plug, offer filling opening, and be provided with the filling opening gland bonnet simultaneously.
Described steel pipe is used to simulate the pressure measurement borehole shape, if simulation boring is long, then is formed by connecting by flange by some joint steel pipes.
Described steel wire simulation crack, its length is less than the length of expansion capsule, and described steel wire is preferably bending.
A liquid receiving vessel is placed in the below of described steel pipe open end, is used to receive the sealing liquid that leaks out.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the present invention is used to detect the used sealing liquid of gas boring pressure tester and the sealing of expansion capsule, it utilizes one section steel pipe simulation boring, end at pipe is provided with the expansion capsule, by in the expansion capsule, suppressing expansion, seal an end mouth of pipe; It passes through seal plug shutoff steel pipe at the other end of pipe, makes between expansion capsule and the seal plug to be one section sealed space.2, it imports solid, liquid, gas three-phase mixing sealing liquid by filling opening and high-pressure delivery pipe in this section seal cavity.3, it is established steel wire by folder and simulates the boring crack between expansion capsule and steel pipe walls, and the ability that flows through the crack by the high pressure mixing sealing liquid detects the sealing of expansion capsule, and the sealing property of sealing liquid.The present invention can detect the sealing of two kinds of sealing mediums simultaneously by a device, and simple to operate, it is comparatively accurate to measure effect simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention
Embodiment
Below in conjunction with drawings and Examples, the present invention will be described in detail.
As shown in Figure 1, apparatus of the present invention mainly are made up of steel pipe, steel pipe filling opening, expansion capsule, seal plug, steel wire, high-pressure delivery pipe, hydraulic pump, expanding foam solution container, stop valve, high-pressure air source etc.
Steel pipe 1 is used to simulate pressure measurement boring, the pressure measurement bore diameter difference of the different expression simulations of its internal diameter; Some joint steel pipes couple together with flange 2, can simulate the pressure measurement boring of different length.End at steel pipe 1 is built-in with expansion capsule 3, and this end steel pipe mouth of pipe need not sealing; The other end at steel pipe 1 blocks the mouth of pipe with seal plug 4.On this section steel pipe 1 between expansion capsule 3 and the seal plug 4, be provided with filling opening and corresponding filling opening gland bonnet 5.Be folded with at least one steel wire 6 between expansion capsule 3 and steel pipe 1, the length outline of steel wire 6 is less than the length of expansion capsule 3, and its different thicknesses, differently curved degree are used to simulate the pressure measurement boring crack of difformity, different sizes on every side.
Be communicated with a high-pressure delivery pipe 7 on the expansion capsule 3, high-pressure delivery pipe 7 passes steel pipe 1, and its other end that exposes is connected to a hydraulic pump 8.Below this end steel pipe mouth of pipe that high-pressure delivery pipe 7 is drawn, a liquid receiving vessel 9 is placed in the mouth of pipe below that just need not to seal.
Also be communicated with a high-pressure delivery pipe 7 on the seal plug 4, the other end of this root high-pressure delivery pipe 7 is connected to an expanding foam solution container 10, and this root high-pressure delivery pipe 7 is provided with stop valve 11 simultaneously.From expanding foam solution container 10, be connected on the high-pressure air source 12, on another root high-pressure delivery pipe 7, also be provided with stop valve 13 by a high-pressure delivery pipe 7.
Whole steel pipe 1 supported with convenient experiment by support 14, and reduces pipe corrosion.
It is as follows to adopt apparatus of the present invention to measure the experimentation of expansion capsule and sealing liquid sealing property:
(1) according to pressure measurement borehole shape, the size that will simulate, determine the length and the thickness of steel pipe 1, then corresponding steel wire 6 and expansion capsule 3 are put into the end of keeping right in the steel pipe 1, by hydraulic pump 8 pressurizations expansion capsule 3 is expanded, expansion capsule 3 expand into and can seal till the steel pipe.
(2) seal plug 4 with steel pipe 1 left end connects, and makes the sealing of steel pipe 1 left end.
