Description
Technical field
It the utility model is related to a kind of new gas pipe bulge test device.
Background technology
Gas pipe is the conventional pipeline of current underground mash gas extraction, to strengthen the extraction management of gas pipe, ensures colliery watt
This extraction pipe-line system safe and highly efficient operation is, it is necessary to which the simple and quick quality to gas pipe is inspected by random samples, and there is an urgent need to one kind
For carrying out the instrument of experimental examination to the gas pipe quality of production.
The content of the invention
The purpose of the utility model is to overcome the shortcomings of above-mentioned prior art, there is provided one kind detection is simple and quick, can ensure coal
The gas pipe bulge test device of ore deposit methane gas extraction pipeline system safe and highly efficient operation.
The utility model includes hydraulic station, blind flange, ball check valve, threeway, plug, pressure gauge, joint and sebific duct；Liquid
Pressure station provides hydraulic power, and gas pipe both ends are equipped with blind flange；Three are respectively equipped with blind flange upper, middle and lower to connect
Mouthful, ball check valve and threeway are equipped with interface, upper interface is a gas vent, for being deflated in pressurization, to ensure
Liquid in gas pipe is full of；Middle part interface is connected on the liquid outlet of hydraulic station by sebific duct, forms hydraulic channel；Bottom
Interface is connected by sebific duct with a joint that can be connected with the liquid inlet of hydraulic station, is connected in the threeway of lower interface
Pressure gauge, for measuring gas overpressure.In general, blind flange upper, middle and lower interface are each provided at one of method
Orchid covers.
Liquid in hydraulic station enters gas pipe by hydraulic station liquid outlet, sebific duct, threeway, ball check valve, while watt
Threeway, ball check valve discharge of the gas from blind flange upper interface in this pipe, ensures that hydraulic pressure is full of and has pressure in gas pipe
Power, reach requirement.The pressure gauge connected on blind flange lower interface can show the pressure of liquid in gas pipe.By joint after experiment
Link together with the liquid inlet of hydraulic station, entered by the sebific duct that is connected on blind flange lower interface, joint discharging liquid
Hydraulic station, form a liquid circulation.
Common gas pipe model DN250, DN300, DN400, DN500, DN600, DN700, DN800, DN900,
DN1000, DN1200 etc..The amount pressure of hydraulic station is 3MPa.Tested gas pipe keeps 15 under 2.0 MPa test pressures
Min, ne-leakage and destruction, it is qualified to be considered as this root gas pipe, is otherwise substandard products.Replacing gas pipe can be tested next after experiment
Part, with this repeatedly.After one gas pipe has been tested, loosen flange and cover screw, pull down gas pipe, change another gas pipe
Continue to test, need to be changed when such as changing the gas pipe of another specification together with ring flange.
The utility model is applied to carry out gas pipe resistance to malleation performance test, compact-sized, small volume, in light weight, effect
Rate height, dependable performance, good appearance, No leakage, detection is simple and quick, can ensure that coal mine gas extraction pipeline system is safe and efficient
Operation.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In figure：1st, hydraulic station, 2, sebific duct, 3,4, threeway, 5, ball check valve, 6, plug, 7, pressure gauge, 8, bolt, 9,
Joint, 10, gas pipe, 11, blind flange.
Embodiment
The both ends of gas pipe 10 are equipped with blind flange 11 by bolt 8, and ball is provided with the upper interface of one of blind flange 11
Shape stop valve and threeway, for being deflated in pressurization.Pass through threeway and sebific duct and spherical section in the middle part interface of the blind flange 11
Only valve 5 and threeway 3 connect, then are connected by sebific duct 2 with the liquid outlet of hydraulic station 1.Lead in the lower interface of the blind flange 11
Cross threeway 4, ball check valve and sebific duct to be connected with joint 9, pressure gauge 7 is connected in the threeway of the lower interface, for measurement watt
This overpressure.Threeway 3 without using through hole be provided with plug 6.
