Portable pressure pipeline flow velocity measuring device

Abstract

The invention provides a portable under-pressure pipeline flow velocity measuring device which comprises a supporting sleeve, a flange is arranged at the bottom of the supporting sleeve, a moving rod is slidably connected into the supporting sleeve, a velocity measuring head is arranged at the bottom end of the moving rod, and a measuring moving meter is arranged at the top end of the moving rod. A positioning mechanism is arranged in the middle of the bottom of the speed measuring head and comprises a fixing cylinder fixed to the bottom end of the speed measuring head, an adjusting rod is slidably connected to the inner wall of the fixing cylinder, scale marks are arranged on the outer wall of the adjusting rod, a clinging block is arranged at the bottom end of the adjusting rod, and the clinging block is of an arc-shaped structure. The attaching block is made of silica gel, and an adsorption groove is formed in the middle of the bottom end of the attaching block. Flanges of different sizes can be selected to install the speed measuring head and the measuring displacement meter on the pipeline under pressure for flow velocity measurement according to the calibers of different pipelines under pressure, and the device is not limited by the size and is convenient to carry and use.

Description

technical field [0001] The invention relates to the technical field of pipeline flow velocity measurement, in particular to a portable pressure pipeline flow velocity measurement device. Background technique [0002] A pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, the high pressure from the pipeline It can also be transported by the pressure or gravity of the fluid itself. The pipeline is widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various In industrial installations, there are many types of pipes, one of which is pressurized pipes. With the development of cities and the continuous increase of population, the urban water pipe network has become more and more overwhelmed. Therefore, the m...
