Description

Large-caliber butterfly valve testing device Technical Field The utility model relates to the technical field of valve detection, in particular to a large-caliber butterfly valve testing device. Background The butterfly valve is required to be subjected to tightness test after being assembled, and for a large-caliber butterfly valve, common test equipment cannot meet the use requirements of the butterfly valve due to the large size and heavy weight, and the butterfly valve is convenient to use, has the defects of insufficient strength, insufficient bearing capacity, unstable applied pressure and easy leakage at two ends of the butterfly valve, and is inconvenient to take and place, requires manual transportation, and is time-consuming, labor-consuming and low in efficiency. Disclosure of utility model Therefore, the utility model aims to provide the large-caliber butterfly valve testing device which is stable and reliable, stable in pressure application, and capable of improving accuracy of a detection result, facilitating hoisting, taking and placing of the butterfly valve and improving detection efficiency. The large-caliber butterfly valve testing device is realized by adopting the following scheme that the large-caliber butterfly valve testing device comprises a base and a gantry seat arranged above the base, a detection table capable of moving forwards and backwards is arranged on the upper side of the base, a supporting seat for placing a butterfly valve is arranged on the detection table, a pressing hydraulic cylinder positioned right above the supporting seat is arranged above the gantry seat, a telescopic rod of the pressing hydraulic cylinder downwards penetrates through the top of the gantry seat and is fixedly connected with a pressing seat for pressing the upper end of the butterfly valve, and a high-pressure medium inlet hole penetrating to the bottom of the detection table is formed in the center position of the supporting seat. Furthermore, the lower orifice of the high-pressure medium inlet is connected with a high-pressure water pipe and a high-pressure air pipe through a three-way pipe, and pressure sensors and valves are arranged on the high-pressure water pipe and the high-pressure air pipe. Further, the front side of the base is provided with a support frame, the upper surface of the support frame is flush with the surface of the base, a pair of guide rails are connected to the support frame and the base, and the bottom of the detection table is connected with a sliding seat in sliding fit with the guide rails. Further, limit stops are respectively arranged at the front end and the rear end of the guide rail. Further, a movable hydraulic cylinder for driving the detection table to move back and forth is arranged on the base, one end of the movable hydraulic cylinder is hinged to the base, and the other end of the movable hydraulic cylinder is hinged to the bottom of the detection table.
