Ultrasonic flowmeter with plugging positioning function

Abstract

The invention discloses an ultrasonic flowmeter with a plugging positioning function. The ultrasonic flowmeter comprises a flow tube body, a measuring tube body, a transducer mounting tube body, a reflector mounting seat, a reflector and a transducer. The ultrasonic flowmeter is characterized in that a positioning sleeve is arranged between the flow tube body and the reflector mounting seat; the positioning sleeve is cylindrical; the center of the positioning sleeve is provided with an ultrasonic channel; the lower end of the positioning sleeve is provided with a positioning inserter; the positioning inserter axially extends along the lower end of the positioning sleeve, thereby facilitating positioning the positioning sleeve onto the reflector mounting seat; the sidewall of the reflector mounting seat is provided with a positioning slot; the positioning inserter matches the positioning slot; the upper end of the positioning sleeve is closely inserted into the transducer mounting tube body and contacts with the transducer; and the lower end is plugged with the positioning slot of the reflector mounting seat for positioning through the positioning inserter. The ultrasonic flowmeter has advantages of novel structure, quick detachment, high positioning accuracy, high fixation reliability, high measurement accuracy, etc.

Description

technical field [0001] The invention relates to the technical field of flow measurement, in particular to an ultrasonic flowmeter with plug-in positioning. Background technique [0002] As we all know, the existing ultrasonic flowmeter is composed of a flow tube body, a measuring tube body, a transducer mounting tube body, a positioning element, a reflector mount, a reflector and a transducer.

[0002] As we all know, the existing ultrasonic flowmeter is composed of a flow tube body, a measuring tube body, a transducer mounting tube body, a positioning element, a reflector mount, a reflector and a transducer. The side wall of the flow tube body is provided with Two transducer installation pipes and positioning holes, the flow pipe body is provided with a measuring pipe body, the transducer installation pipe body communicates with the flow pipe body, and the flow pipe body is connected to the measurement pipe body through the positioning element Phase is fixed, the transducer body is provided with a transducer, the two ends of the measuring tube are respectively equipped with reflector mounts, and reflectors are arranged on the reflector mounts, and the reflector and transducer Correspondingly, the shortcomings of this structure are: 1. Due to the small diameter of the positioning element, the positioning is not accurate enough. Under the repeated impact of the water flow, the positioning of the mirror mounting seat in the measuring pipe section is unreliable

2. Both the flow pipe body and the measuring pipe section need to process positioning holes, which increases the production cost and adds a leakage point at the same time. There is a hidden danger of leakage of the measurement medium during use.
