Problems solved by technology

[0003] When installing the scraper type flowmeter, fix the downstream flange and the upstream flange to both ends of the matching flange with multiple sets of bolts, and then spot weld the contact. This installation method is not convenient enough, so an easy-to-install method is needed Scraper flowmeter to solve the above problems

Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] see figure 1 , the present invention provides a technical solution: a scraper type flowmeter that is easy to install, including a guide assembly, a downstream flange 1, a matching flange 5, a flowmeter body 6 and an upstream flange 7, the left end of the downstream flange 1 is connected to the matching The right end of the flange 5 fits, the right end of the upstream flange 7 fits with the left end of the matching flange 5, the flowmeter body 6 is installed on the upper end of the matching flange 5, and the left and right ends of the matching flange 5 are respectively connected to the upstream flange 7 and the The downstream flange 1 is docked, which is conducive to the next step of spot welding.

[0018] The guide assembly includes a firs...

Abstract

The invention provides an easy-to-mount scraper type flowmeter, comprising a first nut, a first limit plate, a second nut, a second limit plate and a steel rod. The steel rod is mounted at the left end of an upstream flange, and the right end of the steel rod penetrates the upstream flange, a companion flange and a downstream flange sequentially and extends to the right side of the downstream flange. The first nut is mounted at the right side of the circular side of the steel rod. The first limit plate is also mounted at the right of the circular side of the steel rod, and a first guide hole is processed at the right end face of the first limit plate. The second limit plate is mounted at the left of the circular side of the steel rod, and a second guide hole is processed at the left end face of the second limit plate. The second nut is mounted at the left side of the circular side of the steel rod. The design of the easy-to-mount scraper type flowmeter solves the problem that It is inconvenient to mount the conventional scraper type flowmeter as people had to fix the downstream flange and the upstream flange at two ends of the companion flange by multiple groups of bolts before carrying out spot welding at the joints. The scraper type flowmeter is convenient to mount, is reusable, easy to operate and high in reliability.

Description

technical field [0001] The invention is a scraper type flowmeter which is easy to install and belongs to the field of petroleum systems. Background technique [0002] The principle of the scraper flowmeter: When the measured fluid flows into the flowmeter from the inlet of the flowmeter, a pressure difference is generated between the inlet and outlet of the flowmeter, and the pressure difference pushes the scraper and the rotor to rotate, and the rotor rotates every time A certain amount of fluid is discharged, and the instantaneous flow and cumulative flow are obtained by calculating the number of rotations of the rotor. A certain amount of fluid is discharged every time the rotor rotates, and the instantaneous flow and cumulative flow are obtained by calculating the number of rotations of the rotor. [0003] When installing the scraper type flowmeter, fix the downstream flange and the upstream flange to both ends of the matching flange with multiple sets of bolts, and then...
