Description

Technical Field

[0001] The utility model relates to the technical field of flowmeters, in particular to a marine dual-channel ultrasonic flowmeter. Background Art

[0002] The dual-channel ultrasonic flowmeter is a high-precision flow measurement device that uses two channels to measure the flow rate in liquid or gas fluids. It is based on ultrasonic technology and uses the characteristics of sound waves propagating in fluids to achieve flow measurement. The dual-channel ultrasonic flowmeter has the advantages of high precision, no influence from fluid composition and temperature, high reliability, etc. It is widely used in industrial process control, water supply management, sewage treatment, energy monitoring and other fields.

[0003] Dual-channel ultrasonic flowmeters are usually installed in pipelines, which are then connected to the pipeline being measured to measure the flow rate of the fluid. However, since the ship is in continuous motion, the connection between the pipeline and the pipeline being measured will leak the fluid in the pipe after long-term use, which will cause deviations in the data measured by the flowmeter and affect the judgment of the staff.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] See also Figure 1-5 A marine dual-channel ultrasonic flowmeter includes a connecting pipe 1, in which two sets of ultrasonic transmitters and receivers are arranged, and the connecting pipe 1 is connected to a pipe to be measured 2 on both sides through flanges, and the inner walls of the connecting pipe 1 and the pipe to be measured 2 are provided with a first groove 13, and also includes a sealing pipe 3, the thickness of the sealing pipe 3 is the same as the depth of the first groove 13, and first make way grooves 31 are provided at both ends of the sealing pipe 3, and a first sealing ring 32 is installed in the make way groove.

[0025] By setting the sealing tube 3, the sealing tube 3 is installed in the first groove 13 in the tube to be measured 2 and the connecting tube 1, the sealing tube 3 abuts against the side wall of the first groove 13, and the first sealing ring 32 in the first give way groove 31 fits tightly against the side wall of the first groove 13, so that the fluid will not flow out from the connection between the sealing tube 3 and the tube to be measured 2 and the connecting tube 1, and will not affect the measurement of the dual-channel ultrasonic flowmeter, thereby ensuring the accuracy of the measurement data.

[0026] Furthermore, the test tube 2 and the connecting tube 1 are both provided with a second groove 14, the second groove 14 is connected to the first groove 13, and the two ends of the sealing tube 3 are fixedly connected with a pressing plate 33 adapted to the second groove 14. The first groove 13 and the second groove 14 form a stepped side wall, and the sealing tube 3 and the pressing plate 33 abut against the stepped side wall, which reduces the fluid contacted by the first sealing ring 32 and further improves the sealing effect.

[0027] Furthermore, a second clearance groove 34 is formed at the end of the pressing plate 33, and a second sealing ring 35 is installed in the second clearance groove 34. The first sealing ring 32 and the second sealing ring 35 form a double seal to improve the sealing performance of the connection.

[0028] Furthermore, the sealing tube 3 and the pressing plate 33 are made in one piece.

[0029] Furthermore, the connection line between the transmitter and the receiver intersects with the axis of the connecting pipe 1. When the connection between the generator and the receiver is parallel to the axis of the connecting pipe 1, the generator and the receiver on the front side of the fluid movement direction will cause the water flow velocity to be hindered, thereby affecting the accuracy of the measurement result; specifically, the connection lines of the two sets of generators and receivers intersect with the axis of the connecting pipe 1 to improve the accuracy of the measurement data.

[0030] Working principle: The sealing tube 3 is installed in the first groove 13 in the tube to be tested 2 and the connecting tube 1, the sealing tube 3 and the pressure plate 33 are in contact with the side walls of the first groove 13 and the second groove 14, and the first sealing ring 32 in the first make way groove 31 and the second sealing ring 35 in the second make way groove 34 are tightly fitted on the corresponding side walls, forming a double sealing effect, so that the fluid will not flow out from the connection between the sealing tube 3 and the tube to be tested 2 and the connecting tube 1, will not affect the measurement of the dual-channel ultrasonic flowmeter, and ensure the accuracy of the measurement data.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
