Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flow meters, in particular to a metal tube float flow meter with a multifunctional support. BACKGROUND

[0002] The float of the metal tube float flow meter moves upward in the measuring tube as the flow changes, and at a certain position, the buoyancy of the float and the gravity of the float reach equilibrium, at which time the flow area between the float and the orifice plate remains constant, and the flow area is proportional to the height of the float, that is, the position of the float in the measuring tube represents the size of the flow, and the position of the float is transmitted to the external indicator by the internal magnet, so that the indicator correctly indicates the flow value at that time, which makes the indicator shell not in direct contact with the measuring tube, so that even if a limit switch or a transmitter is installed, the instrument can be used in high temperature and high pressure working conditions, and in use, flange rings are usually arranged at both ends of the indicator pipe, and then the flange rings and the corresponding to-be-measured pipes are connected and fixed by bolts and nuts.

[0003] In use, the structure of the traditional flow meter is relatively simple, and usually the bolts are fixed separately in sequence, which can easily cause the previously fixed bolts to loosen and be unstable when fixing other bolts subsequently, thereby causing uneven stress at the connection part of the flange ring, and thus easily causing liquid leakage or leakage, and in use, the simple connection with the pipe can easily cause uneven stress due to different measuring pipe materials, thereby causing additional weight of the pipe, and in use, the flow meter often easily causes impurities to enter when measuring some non-pure substances, which then requires cleaning of the inside of the pipe, and the traditional bolt and nut fixing is relatively troublesome to disassemble. SUMMARY

[0007] Preferably, the extrusion subassembly includes a clamping piece, a telescopic rod, and an extrusion spring, the telescopic rod is fixedly connected with the clamping piece at the inner protruding end, and the outer wall of the telescopic rod is provided with the extrusion spring, the clamping piece is arc-shaped and inclinedly arranged at the one end close to the through-hole, and the side wall of the clamping piece is provided with anti-skid teeth.

[0008] Preferably, the telescopic rod and the side wall of the moving ring are fixedly connected with each other, the extrusion spring and the moving ring are fixedly connected with each other, the both sides of the one side of the through-hole away from the flange ring are provided with the clamping pieces, and the clamping pieces and the moving ring are slidably connected with each other.

[0010] Preferably, the top outer wall of the sliding plate is sleeved with the outer wall of the measuring pipe, the top center of the measuring pipe is rotatably installed with a display, the bottom of the extending plate and the top of the fixed plate are rotatably connected with each other, and the inside of the fixed plate is provided with a plurality of fixed holes.

[0011] Preferably, the one side edge of the through-hole close to the extrusion subassembly is provided with the push piece, the both sides of the one side of the push piece close to the clamping piece are arc-shaped and inclined, the one end of the push piece away from the extrusion subassembly is fixedly connected with the fixed ring, the inside of the fixed ring and the baffle sleeve are slidably connected with each other, and the one side of the moving ring is connected with the fixed ring through a plurality of fixed springs.

[0012] Preferably, the inside of the fixed tooth ring is provided with the screw rod, the one end of the fixed tooth ring is rotatably connected with the flange ring through the screw rod, the one end of the screw rod away from the flange ring is rotatably connected with the moving ring through the screw thread, and the inner wall of the internal tooth ring is meshed with the fixed tooth ring through the surrounding teeth.

[0015] 1. In use, the flange rings at both ends of the measuring tube can be conveniently matched with the pipeline to be measured, and then the bolts to be fixed are inserted into the shielding sleeve through the flange rings, so that the clamping pieces are driven by the compression springs to approach each other, thereby achieving clamping and compression fixation of the bolts. Further rotation of the inner tooth ring can drive the fixed tooth ring to rotate, thereby driving the screw rod to rotate, so that the moving ring is uniformly pushed to the center of the measuring tube, thereby driving the bolts to move further through the compression assembly, and uniform compression of the measuring tube is achieved to prevent uneven stress on different parts.

[0016] 2. When installing, the support assembly can be started, and then the extension plates are pulled to the bottom, thereby driving the fixed plates at the bottom to move. Rotation of the support assembly around the measuring tube can well drive the fixed plates to rotate, thereby adjusting the position to be supported and installed. When the extension plates move, if the extension distances of the two extension plates are different, the fixed plates can be inclined to one side, thereby achieving further adjustment. The extension plates can be fixed by rotating the fixed bolts, thereby fixing the position and angle of the fixed plates.

[0017] 3. When disassembling and cleaning are needed, the inner tooth ring can be directly rotated in reverse, thereby moving the moving ring in reverse to release the pushing of the compression assembly, thereby reducing the fixation and compression stress of the bolts, so that the clamping pieces can move. The fixed ring is further pushed to one side of the flange ring, thereby causing the pushing pieces to extrude the clamping pieces to move to both sides, thereby releasing the fixation of all the bolts as a whole, which is very rapid and convenient.
