Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeter water meter equipment, in particular to an installation structure of an ultrasonic flowmeter water meter. Background Technique

[0002] The main problems existing in the measurement of flow velocity by ultrasonic water meters at present are as follows: the static time difference (also known as zero-flow time difference) of ultrasonic water meters is not zero, that is, when the fluid in the measuring pipe is in a static state, the obtained ultrasonic time difference is not zero. The ultrasonic time difference refers to the difference between the ultrasonic time against the flow and the ultrasonic time with the flow. Usually, the static time difference of ultrasonic water meters fluctuates at a certain offset (such as fluctuating at 100 ps), and the offsets of the static time differences of different ultrasonic water meters are different (possibly ranging from -50 ps to 200 ps). The said offset has a great influence on the measurement consistency of small-flow fluids. The measurement consistency refers to the fluctuation range of the measurement accuracy when several ultrasonic water meters measure the same flow rate simultaneously. The measurement accuracy refers to the ratio of the flow measurement value of the water meter to the standard flow rate adjusted by the flow bench. In the prior art, the vibration generated when water flows through the pipeline will also directly act on the water meter. Over time, it will cause the accuracy of the water meter to decline or even malfunction. Long-term vibration may cause the connection part between the water meter and the pipeline to become loose or even leak, increasing potential safety hazards.

[0003] For example, an installation structure of an ultrasonic flowmeter water meter disclosed in the authorized patent document with the application number CN202021075528.2 includes a support block. A clamping assembly is arranged at the bottom of the support block. The clamping assembly consists of an upper clamping ring, a lower clamping ring, two protective tubes, two connecting rods and two first springs. An adjusting assembly is arranged at the top of the support block. The adjusting assembly consists of a threaded rod, a threaded tube, a mounting plate and mounting holes. The number of mounting holes is two. A locking assembly is arranged at the top of the mounting plate. The locking assembly consists of a toothed ring, a support plate, a limiting rod, an arc-shaped clamping block and a second spring. Auxiliary assemblies are arranged on both sides of the top of the support block. Through the mutual cooperation of the protective tube, the connecting rod and the first spring, the upper clamping ring and the lower clamping ring of this utility model can clamp ultrasonic flowmeter water meters with different diameters, so that this installation structure can meet the use requirements of ultrasonic flowmeter water meters with different diameters, thereby improving the practicability of this installation structure.

[0004] The above patent lacks a good buffering and shock-absorbing effect on the installation of the ultrasonic flowmeter water meter, resulting in fine vibrations generated when water flows through, and the bolts at the connection part are prone to looseness after a long time. Therefore, we need to provide an installation structure of an ultrasonic flowmeter water meter. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an installation structure for an ultrasonic flowmeter water meter. By placing the ultrasonic flowmeter water meter on the bottom plate, a glue layer sheet is provided on the top of the bottom plate to protect the outer pipe of the ultrasonic flowmeter water meter. At the same time, two limiting frames can slide in the chute to adapt to ultrasonic flowmeter water meters of different specifications. The two limiting frames are attached to the ultrasonic flowmeter water meter, and the lower ends of the limiting frames penetrate through the bottom of the mounting plate and are threadedly installed through fixing nuts to fix the ultrasonic flowmeter water meter on the bottom plate. During the use of the ultrasonic flowmeter water meter, it will attempt to vibrate, and the vibration is transmitted to the rod body through the bottom plate, driving the rod body to float in the pipe body. A damping oil is filled at the top of the sealing piston in the pipe body, and the bottom of the sealing piston is a chamber filled with gas. As the rod body drives the sealing ring to move, the damping oil circulates through the hole parts on the surface of the sealing ring, generating a damping force, and the floating of the sealing piston compresses the gas to absorb the vibration. The movement of the base drives the deformation of the support spring, and the support spring serves to reset the bottom plate. Four rod bodies at the bottom of the bottom plate are arranged to slide within the base plate to enhance the guiding property of the floating of the bottom plate, thus solving the problems raised in the above background technology.

During the use of the ultrasonic flowmeter water meter, it will attempt to vibrate, and the vibration is transmitted to the rod body 42 through the bottom plate 2, driving the rod body 42 to float in the pipe body 41. Damping oil is filled at the top of the sealing piston 403 in the pipe body 41, and the bottom of the sealing piston 403 is a chamber filled with gas.
