Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of hydraulic prop down-hole package seal checker, can carry out sealing pressurize easily and fast detect in down-hole to hydraulic prop.
To achieve these goals, the technical solution adopted in the utility model is: a kind of hydraulic prop down-hole package seal checker, comprises pressurize box, retaining valve, hydraulic power unit, pressure transducer and signal detecting and measuring apparatus; Pressurize box is made up of upper press cover and U-shaped lower cover, upper press cover passes through to be connected hinge with one end of lower cover, the other end is bolted, upper press cover offers O shape through hole, coaxial with the U-shaped hole of lower cover, upper press cover has inlet, and inlet is connected with retaining valve by screw thread, and is connected to hydraulic power unit by pipeline; Pressure transducer is arranged on pressurize box and retaining valve associated line, and is connected with signal detecting and measuring apparatus by cable, and pressure transducer and signal detecting and measuring apparatus housing adopt isolation Explosion-proof Design, and circuit intrinsic safe explosion-proof designs, and circuit adopts signal isolation to amplify.
Further, gasket seal, y-type seal ring and anti-extrusion ring is provided with in upper press cover.
Further, U-shaped rubber sheet gasket is installed in lower cover.
The beneficial effects of the utility model are: hydraulic power unit provides hydraulic pressure to pressurize box, and pressure transducer sends pressure signal to signal detecting and measuring apparatus, carry out sealing pressurize test in required time.When hydraulic prop exist leak time, pressurize box pressure can change, by signal detecting and measuring apparatus, can the airtight quality of quick and convenient detection hydraulic prop, the hydraulic prop of seal failure is reported to the police.This device volume is small and exquisite, can be carried to down-hole easily, without the need to carrying hydraulic prop, detects on the spot, and the hydraulic prop after airtight quality detection is qualified can be recycled.
