Abstract

The invention relates to large-caliber all-welded ball-valve integrated multifunctional detection equipment. The equipment comprises a pedestal, a main frame, a movable vehicle, a lower sealing plate, an upper sealing plate, a detection system and a control box body. The main frame is connected to an upper portion of the pedestal through a stress shaft. Two horizontal tracks are arranged on the pedestal. The movable vehicle is movably connected between the two horizontal tracks. The lower sealing plate is installed on an upper surface of the movable vehicle. The upper sealing plate is arranged between the pedestal and the main frame. The upper sealing plate is connected to a cylinder body through an upper pressing plate. The cylinder body is installed on the main frame. The control box body is arranged on one side of the pedestal. The control box body is provided with a detection instrument assembly and a switch assembly. The detection instrument assembly and the switch assembly are connected to the detection system respectively. Through the design of the invention, automatic control is used to replace manual work, clamping to the valve and sealing of two ends of the valve are realized, and an effect of increasing detection equipment work efficiency is achieved.

Description

technical field [0001] The patent of the present invention relates to a detection device, in particular to a large-caliber all-welded ball valve integrated multifunctional detection device. Background technique [0002] In the prior art, when testing a ball valve, a gasket or a sealing ring is usually placed on the outside of both ends of the ball valve, and then a cylinder or other device is used to clamp the nozzles of the connecting pipe fittings at both ends of the ball valve, so that the gasket or sealing ring is connected to the ball valve. The end is sealed, and the whole sealed ball valve is immersed in water, and then compressed gas is passed into the ball valve to test its sealing performance. Moreover, the traditional horizontal pressure testing machine is quite inconvenient for clamping large-diameter valves; in addition, when testing the strength and pressure, due to the structural problems of the valve, it is often impossible to clean the air in the cavity, cau...
