The utility model is characterized in that the air tube (9) is connected with one port of a three-way valve (2), and the other port of the three-way valve (2) is connected with a one-way air tap (4). The utility model has the advantages that the device is connected with the air tube to be used, is easy to carry and transport, is convenient to operate, can adapt to different environments for operation, expands the range of application and increases work efficiency.
Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering geological mapping device, especially a kind of capsule embolism air feed pressure tester of the water injection test that is used to hole.
Background technology
" Hydraulic and Hydro-Power Engineering water injection test rules " (SL345-2007) are stipulated, to the boring water injection test, examination section sealing can adopt water-stopping methods such as embolism or set of pins clay, should guarantee that sealing is reliable.
At present, the embolism water-stopping method comprises hydraulic type embolism water-stopping method, top pressing type embolism water-stopping method and vapour-pressure type embolism water-stopping method.Hydraulic type embolism water-stopping method is by the water of input certain pressure in embolism, and embolism is expanded, and is close to drill hole wall, isolates the examination section; Top pressing type embolism water-stopping method is by applying vertical pressure to the embolism two ends, embolism is expanded, be close to drill hole wall, isolating the examination section; Vapour-pressure type embolism water-stopping method utilizes air pump or oxygen cylinder etc. to the inflation of capsule embolism usually, and the capsule embolism is expanded, and is close to drill hole wall, isolates the examination section.
Device such as the air pump of above method, especially vapour-pressure type embolism water-stopping method or oxygen cylinder is heavy, is unfavorable for carrying transportation, and operation inconvenience, and length consuming time, work efficiency are not high.
The utility model content
The purpose of this utility model is exactly in order to overcome existing air pressure embolism antipriming heaviness, to be unfavorable for carrying the defective of transportation, and the air feed pressure tester of boring water injection test capsule embolism is provided, and this device is easy to use, is beneficial to carry.
The technical scheme that its technical problem that solves the utility model adopts is:
The air feed pressure tester of boring water injection test capsule embolism comprises capsule embolism and the tracheae that is connected, and it is characterized in that: port of tracheae and three way cock is connected, and the another port of three way cock is connected with unidirectional valve.
Described air pressure capsule embolism by interior pipe, go up lower contact, help pull a cart and rubber tube is formed in the top up and down.
Described tracheae directly inserts in the port of three way cock, reinforces with seccotine then to get final product.
Unidirectional valve can adopt valve commonly used, is made of air inlet port, gas outlet, valve body, spool, spring; Air inlet port is connected with the tracheae of inflator, and the gas outlet is connected with three way cock by the flange on the valve body.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
The 3rd port of three way cock is provided with pressure meter, is provided with internal thread at the place, connectivity port of three way cock and is connected with pressure meter, and pressure meter is used to measure capsule embolism internal gas pressure.
Be provided with sealing ring between three way cock and unidirectional valve, and be fastenedly connected by nut.
Three way cock is provided with bearing.
The beneficial effects of the utility model are that device is connected use with inflator, are easy to carry about with one, transport, and are easy to operate; Can adapt to different environment operations, enlarge the scope of application; Improved operating efficiency.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings:
Fig. 1 is a front view of the present utility model.
1. pressure meters among the figure, 2. three way cock, 3. air valve nut, 4. unidirectional valve, 5. inflator, 6. hold-down nut, 7. sealing mat, 8. bearing, 9. tracheae, 10. water injection pipe, 11. capsule embolisms.
The specific embodiment
As shown in Figure 1, the air feed pressure tester of the utility model boring water injection test capsule embolism, comprise capsule embolism 11, capsule embolism 11 is a double-decker, the middle part is provided with air bag, air bag is connected with tracheae 9 one ends, the other end of tracheae and airtight connection of three way cock 2 one ends, the other end of three way cock is provided with external screw thread, male end is fixedlyed connected with unidirectional valve 4 by air valve nut 3, also being provided with sealing mat 7 in the junction of three way cock and unidirectional valve seals, unidirectional valve 4 is provided with external screw thread, and male end and hold-down nut 6 are connected, and can seal one way valve to regulate and fastening adjustment, the 3rd port of three way cock 2 is provided with internal thread and is connected with pressure meter 1, and the valve body of three way cock is provided with bearing 8 and is used for supporting and placing.
Dynamic duty process: before the boring water injection test, inflate to capsule embolism 11 on ground, the capsule embolism is expanded, check whether firm tracheae 9 is connected with capsule embolism 11, unidirectional valve 4 etc., whether leak gas, confirm firm, air tight after, water injection pipe 10 and capsule embolism are arrived precalculated position in the boring 11 times, fixing capsule embolism, unidirectional valve and 5 airtight connections of inflator are to 11 inflations of capsule embolism, pressurization, the capsule embolism is slowly expanded, be pressurized to scheduled pressure value, the capsule embolism is closely contacted with drill hole wall, carry out the work of water injection test reading again.Whether in the process of the test, observe pressure meter 1 indicating value and change, when manometric indicating value decreased, the suitable ftercompction of reply capsule embolism closely contacted with drill hole wall to keep the capsule embolism.After the off-test, pull up tracheae, discharge gas in the capsule embolism, take out the capsule embolism.
