An industrial flow meter for multi-directional flow according to claim 6, characterized in that the shim plate (28) and the connection disc (6) are provided with a plurality of screw holes inside each, and the shim plate (28) corresponds to the screw holes inside the connection disc (6), and a plurality of adjusting bolts (27) are connected between the connection disc (6) and the shim plate (28).
8. A method of use for a multi-way flow industrial flow meter according to claim 1, wherein the method of use comprises the steps of:
the method comprises the following steps: connecting the flowmeter body (1) with an external water pipe, wherein when the flowmeter body is connected with the external water pipe, one end of a connecting pipe (2) is connected with a pipe interface outside the flowmeter body (1) through threads, and the other end of the connecting pipe (2) is inserted into the water pipe; after the other end of the connecting pipe (2) is inserted into the water pipe, the sealing mechanism (20) enters the water pipe together; the buffer layer (25) pushes the outer plate (23) to be tightly abutted against the inner wall of the water pipe, the outer part of the rubber elastic sealing block (24) is abutted against the inner wall of the water pipe, and the sealing mechanism (20) seals the joint between the water pipe and the connecting pipe (2);
step two: after the connecting pipe (2) is connected with a water pipe, a connecting disc (6) of an external pipeline interface of the flowmeter body (1) is fixedly connected with a connecting disc (6) at the end part of the water pipe through a bolt rod, the two connecting discs (6) are close to each other and are extruded to extrude a damping spring (26) at the end part, backing plates (28) at the end part are in close contact with each other, and the pipeline interface and the water pipe are fixed; if the flowmeter body (1) is installed with a water pipe, the length of a pipeline interface at the end part is limited, and when the length is limited, the connecting pipe (2) is inserted into the water pipe; an adjusting bolt (27) is installed and connected with the connecting disc (6), penetrates through the connecting disc (6) and is connected with the backing plate (28) to limit the backing plate (28); then, the bolt rods are used for connecting the backing plates (28) at the two ends, and the backing plates (28) are used for connecting and fixing the water pipes;
step three: before the flowmeter body (1) is connected with a water pipe, a protective shell (3) is arranged outside the flowmeter body; the side shells (17) on the two sides are clamped with each other and installed outside the flowmeter body (1), and the two side shells (17) are fixedly inserted into the jacks (18) through plugs (19) at the upper end and the lower end; a plurality of suckers (12) inside the side shell (17) are bonded with the outside of the flowmeter body (1); after the flowmeter body (1) falls on the ground in transportation, the telescopic rod (13) moves in the sleeve (16), and after the plurality of balls (5) outside the protective shell (3) are contacted with the ground, the balls roll on the ground, so that the friction force is reduced;
step four: when the flowmeter body (1) is used and the weather is cold, the wire holder (4) is connected with an external power supply, the plurality of electric heating pieces (10) work to generate heat to heat the flowmeter body (1), and water in the flowmeter body (1) does not freeze when flowing.
