Description

Technical Field

[0001] The utility model relates to the technical field of vortex flowmeters, and more specifically to an auxiliary installation device for vortex flowmeters. Background Art

[0002] The vortex flowmeter is developed and produced based on the Karman vortex principle. It is mainly used for flow measurement of industrial pipeline media, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large range, high accuracy, and is almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring working volume flow. There are no movable mechanical parts, so it has high reliability and low maintenance. The instrument parameters can be stable for a long time. The vortex flowmeter uses a piezoelectric stress sensor with high reliability and can be used at -20℃~

[0003] It works within the working temperature range of +250℃. It has analog standard signal and digital pulse signal output, and is easy to use with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.

[0004] After searching, the existing patent number is CN215326665U, which is an auxiliary installation device for a vortex flowmeter, including a roller, a base, a lifter, a bottom support plate, a fixer, a top crossbeam and a top fixed assembly. The base is arranged on the roller, the lifter is arranged on the base, the lifter is symmetrically provided with two groups, the bottom support plate is arranged on the lifter, the fixer is arranged on the bottom support plate, the fixer is symmetrically provided with two groups, the top crossbeam is arranged on the top of the lifter, the top fixed assembly is arranged at the bottom of the top crossbeam, the top fixed assembly is symmetrically provided with two groups, and the fixer includes a fixing plate, a pushing motor, a screw, a threaded sleeve, a clamping plate and a telescopic rod.

[0005] For the commonly used vortex flowmeter, when it is installed relative to the external pipeline, since the outside of the flowmeter does not have an auxiliary support component, the installer is required to hold and support the flowmeter with his hands during the installation process, which is inconvenient for installation and fixation, and reduces the assembly efficiency. Therefore, we proposed an auxiliary installation device for vortex flowmeter to solve the above-mentioned problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] In view of the problems existing in the prior art, the purpose of the utility model is to provide an auxiliary installation device for a vortex flowmeter. The supporting assembly at the bottom of the valve body includes a carrier, a self-locking telescopic frame and a bottom plate. When the valve body is assembled relative to the pipeline, the carrier is first fixed to the valve body by magnetic attraction through a permanent magnet. According to the distance between the valve body and the supporting surface, the length of the self-locking telescopic frame is adjusted by pushing and pulling until the bottom plate fits on the supporting surface. The bottom plate then assists in supporting the valve body through the self-locking telescopic frame and the carrier, thereby improving stability. There is no need to support the valve body by hand, and the installation is more time-saving and labor-saving.
