Problems solved by technology
[0003] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the detection device for butterfly valve airtightness cannot adjust the detection devices located at both ends of the butterfly valve according to the size of the butterfly valve, so that the airtightness of the butterfly valve cannot be accurately tested, resulting in the failure of the butterfly valve. Poor airtightness affects users, and a butterfly valve airtightness detection device is proposed

The invention discloses a butterfly valve sealing performance detection device which comprises two opposite connecting rings. A rotating groove is formed in one end of each connecting ring, clamping connection rings are arranged in the rotating grooves, clamping rods are symmetrically arranged at two ends of each clamping connection ring, a connecting seat is arranged on one side of each clampingrod, mounting grooves are formed in the connecting seats, rotating rods are rotatably connected in the mounting grooves, a limit plate is rotatably connected at one end, far away from each connectingseat, of the corresponding rotating rod, moving plates are arranged above the limit plates, a placing groove is formed in one side of each limit plate, rotating blocks are rotatably connected in the placing grooves, and a threaded rod is arranged on one side of each rotating block. According to the device, the two clamping connection rings can move towards one side, the distance between the two clamping connection rings is rapidly adjusted by a user, the clamping connection rings are connected with the connecting rings in a clamping manner, so that the whole detection device can be rapidly assembled and disassembled, and overhaul and maintenance of the user are facilitated.
Description
technical field [0001] The invention relates to the technical field of a butterfly valve sealing performance detection device, in particular to a butterfly valve sealing performance detection device. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline media. A valve; the valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjustment. However, the current butterfly valve sealing test device cannot be adjusted according to the size of the butterfly valve. The detection device at the ...
