Description

Technical Field

[0001] The utility model relates to the technical field of target flowmeters, in particular to an online installed target flowmeter. Background Art

[0002] Target flowmeters are widely used in industrial fluid measurement. Their operating principle is based on Newton's second law and the principles of fluid mechanics, calculating flow rate by measuring the impact force of the fluid on a target plate. Specifically, when fluid flows through a target flowmeter, the target plate is subjected to a thrust proportional to the fluid's kinetic energy and the target plate's area. The displacement of the target plate is converted into an electrical signal by a displacement sensor. The magnitude of the electrical signal is proportional to the fluid flow rate, thereby enabling flow measurement.

[0003] When installing a traditional target flowmeter, the flanges at both ends of the flowmeter are fixed to one end of the connecting pipe by bolts. In order to facilitate the alignment of the bolts, the flowmeter needs to be lifted and supported during installation, which is inconvenient for subsequent installation and positioning operations. Moreover, after the connection is fixed only with bolts, the bolts are prone to loosening during later use, causing one end of the connecting pipe to fall off from one end of the flowmeter. Therefore, corresponding improvements are needed to address the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide an online mounted target flow meter to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an online mounted target flowmeter, comprising a target flowmeter body, an outer surface of the target flowmeter body being installed with a flange 1 at both ends, and one side of the flange 1 being provided with four groups of screw holes, and the side surface of the flange 1 being provided with four groups of limit columns 1, connecting pipes being movably inserted into the interior of both ends of the target flowmeter body, and a flange 2 being installed on the side surface of the connecting pipe, one side of the flange 2 being provided with four groups of fixing holes, and four groups of limit columns 2 being installed on the side surface of the flange 2, the outer surfaces of the limit columns 1 and the limit columns 2 being provided with limit plates through the limit holes, and side plates being installed on both sides of the limit plates, the interiors of the side plates being movably screwed with screws, and one end of the screws being provided with a hand-held rod.

[0006] Preferably, an arc-shaped plate is installed on the side surface of the target flowmeter body near the bottom end, and an electric push rod is installed on the bottom end of the arc-shaped plate, and a mounting plate is installed on the bottom end of the electric push rod.

[0007] Preferably, limiting holes are provided at both ends of the limiting plate.

[0008] Preferably, the bottom ends of the limiting plates are all arc-shaped, and the bottom ends of the limiting plates are all fitted with the side surfaces of the first flange and the second flange.

[0009] Preferably, the outer diameter of the screw rod is adapted to the inner diameter of the screw hole and the fixing hole, and one end of the corresponding screw rod is movably threadedly connected to the inside of the corresponding screw hole and the inside of the corresponding fixing hole.

[0010] Preferably, the inner circumferential array of the mounting plate is provided with mounting holes.

[0011] Preferably, the length of the limiting plate is adapted to the sum of the thicknesses of the flange 1 and the flange 2.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The arrangement of components such as flange 1, screw hole, limit column 1, connecting pipe, flange 2, limit column 2, fixing hole, limit plate, limit hole, side plate, screw, hand-held rod, arc plate, electric push rod and mounting plate can effectively solve the problem that during the installation of traditional target flowmeter, the flanges at both ends of the flowmeter are fixed to one end of the connecting pipe by bolts. In order to facilitate the alignment of the bolts, the flowmeter needs to be lifted and supported during installation, which is not convenient for subsequent installation and positioning operations. Moreover, after the connection is fixed only with bolts, the bolts are prone to loosening during later use, which causes one end of the connecting pipe to fall off from one end of the flowmeter.

[0014] The user can movably insert one end of the connecting pipe into the interior of one end of the target flowmeter body, and make the inner surface of flange two fit with the outer surface of flange one. As shown in the figure, flange two is set at a position close to one side of the outer surface of the connecting pipe, so that one end of the connecting pipe is extended into the interior of one end of the target flowmeter body, thereby being able to play a preliminary limiting card connection. After that, the user can put the limiting plate on the outer surface of limiting column one and limiting column two through the two sets of limiting holes opened inside the limiting plate, so that the bottom end of the limiting plate can fit with the side surfaces of flange one and flange two. At this time, the inner surface of the side plate can respectively fit with one side surface of flange one and flange two. The screw rod can be rotated by the hand-held rod so that one end of the screw rod can be inserted into the corresponding fixing hole and screwed to install. At this point, the installation operation between one set of limit plates and flange one and flange two is completed. Similarly, the other three sets of limit plates can be installed between flange one and flange two in the same way, thereby finally completing the installation operation of one set of connecting pipes and one end of the target flowmeter body. Similarly, the other set of connecting pipes can be installed with the other end of the target flowmeter body in the same way, thereby finally presenting the state shown in the figure, thereby using the target flowmeter body to detect the flow of water between the two sets of connecting pipes.

At this time, the arc plate 4 can be moved upward or downward under the operation of the electric push rod 41, so that the target flowmeter body 1 can move accordingly, so that the height of the target flowmeter body 1 can be adjusted in real time according to the actual working environment. When the height of the target flowmeter body 1 is adjusted, the user can movably insert one end of the connecting pipe 2 into the interior of one end of the target flowmeter body 1, and make the inner surface of the flange 21 fit the outer surface of the flange 11.
