Rainproof device for rotary piston flow meter

Abstract

The invention provides a rainproof device for a rotary piston flow meter. The rainproof device comprises a transparent lower shell body, a transparent upper shell body, a rotary piston flow meter mainbody, a metal plate, scraping rubber and a vertical plate, wherein the upper end of the transparent lower shell body is mounted on the transparent upper shell body through a bolt; the transparent lower shell body and the transparent upper shell body are mounted on the rotary piston flow meter main body; the vertical plate is welded at the upper end of the transparent upper shell body; the metal plate is mounted at the front end of the vertical plate; the scraping rubber is stuck at the lower end of the metal plate; the scraping rubber is mounted at the upper end of the transparent upper shellbody. By adopting the design, a rainproof function is realized and a worker can conveniently observe the rotary piston flow meter main body; the rainproof device has a rainproof function, is safe andreliable and is convenient to clean.

Description

technical field [0001] The invention relates to a rainproof device for a rotary piston flowmeter, which belongs to the technical field of petrochemicals. Background technique [0002] The rotary piston flowmeter is a positive displacement flowmeter, which is mainly used to measure the flow of liquid. Its working principle is that when the flowmeter is connected to the pipeline and oil flows through, the pressure difference on both sides of the inlet and outlet will push the piston to make a rotary motion. At this time, the magnetic coupling connected to the piston will also rotate accordingly. The number of revolutions is proportional to the amount of oil flowing through the flowmeter, so the number of piston revolutions recorded by the counting mechanism is a multiple of the amount of oil flowing through the flowmeter. Rotary piston flowmeters installed outdoors require good rain protection measures. [0003] In the prior art, the rainproof shell is usually used to protec...

Problems solved by technology

[0003] In the prior art, the rainproof shell is usually used to protect the rotary piston flowmeter from rain, so as to prevent the rotary piston flowmeter from being damaged, but when the staff needs to observe the data of the rotary piston flowmeter, they need to find other tools to protect the rotary piston flowmeter The rainwater and impurities remaining on the device are cleaned up, which is cumbersome and time-consuming
