Background technology
When using rate-of flow in ultrasonic flow rate measurement buret road, need the mounting distance shown according to effusion meter, sensor (probe) is fixed temporarily and fits on the outer tube wall of pipe under test, so that sensor (probe) can successfully be launched and received ultrasonic signal.Utilized iron chains or other material that sensor (probe) is bundled in the fixed form of outer tube wall of pipeline in the past, and when measuring large-diameter pipeline flow, be difficult to make ultrasonic signal linearly launch and receive;Especially for the end, buried ground, radial direction the most barish large-diameter pipeline during measurement, sensor (probe) cannot be bundled by whole circle especially so that measure work efficiency low, increase the operation frequency and the labor intensity of tester.
Summary of the invention
The purpose of this utility model is, according to problem present in existing big-diameter pipeline flow rate test, it is provided that a kind of convenience, practical measuring ultrasonic wave flow sensor Large Diameter Pipeline fixture.
The technical solution of the utility model is, this utility model one measuring ultrasonic wave flow sensor Large Diameter Pipeline fixture is made up of magnetic fixing, locating slide rod, ultrasonic sensor and caging bolt.Ultrasonic sensor is installed in the groove of magnetic fixing lower end;Caging bolt is arranged in the screw in magnetic fixing;The rail groove of locating slide rod two end inserts in two magnetic fixing respectively, and caging bolt is through the rail groove top pressure ultrasonic sensor of locating slide rod two end.
Magnetic fixing includes two the first identical magnetic fixing being positioned at tested pipeline upstream and downstream with cancave cambered surface and the second magnetic fixing, the cancave cambered surface of two magnetic fixing can be close on big-diameter pipeline exterior arc surface, and two magnetic fixing are at an axially spaced segment distance of tested pipeline.
Caging bolt is arranged in magnetic fixing, is attached to big-diameter pipeline exterior arc surface for being fastened by ultrasonic sensor.
Ultrasonic sensor is arranged in the groove in the first magnetic fixing and the second magnetic fixing, the rail groove of locating slide rod two end inserts in two magnetic fixing respectively, the caging bolt being arranged in the first magnetic fixing and the second magnetic fixing is each passed through the rail groove of locating slide rod two end, top pressure ultrasonic sensor, recline big-diameter pipeline exterior arc surface by ultrasonic sensor.
The middle part in locating slide rod face is provided with level indicator, and with rail groove in the middle part of locating slide rod two end, locating slide rod two limit marginal distribution along its length have scale.Rail groove width is slightly larger than the diameter of caging bolt.
Operation principle of the present utility model is, utilize the magnetic force in magnetic fixing, the cambered surface that can make magnetic fixing is axially adsorbed on steel pipe along pipeline outer wall, will be distributed on pipeline, two magnetic fixing in downstream are respectively fitted on the rail groove of locating slide rod two end, the subsidiary scale of locating slide rod and level indicator is utilized to adjust the test position of magnetic fixing, sensor (probe) is inserted in magnetic fixing groove, and screw caging bolt, sensor (probe) is made to be closely adhered on the outer tube wall of pipe under test, so that ultrasonic signal energy normal transmission.
Of the present utility model have the technical effect that (1) this utility model is suitable for interim fixing on big-diameter pipeline of measuring ultrasonic wave flow sensor (probe), be easy to dismounting;(2), when this utility model screws caging bolt, sensor (probe) can be closely adhered on the outer tube wall of pipe under test;(3) this utility model is connected upstream and downstream magnetic fixing by locating slide rod so that upstream and downstream sensor (probe) is linearly arranged;And the incidental level indicator of locating slide rod can ensure that upstream and downstream probe is parallel to pipe centerline, so that it is guaranteed that the normal transmission of ultrasonic signal;(4) this utility model magnetic fixing position can adjust location according to the scale that locating slide rod is subsidiary.
This utility model is mainly used in measurement unit and utilizes the operation field of ultrasonic flow rate measurement amount big-diameter pipeline fluid flow.
