Abstract
The utility model discloses a kind of inner cam type blade flowmeter, the inner chamber of housing is cam face, two opposed, the outside of housing is respectively equipped with liquid-inlet and liquid outlet, upper cover and lower cover is fixed with respectively at the upper and lower side of housing, axis is provided with in the middle of runner, the top and bottom of described axis be rotatably installed in respectively upper cover and under cover, runner along the circumferential direction has four vertical slots uniformly, the upper and lower side of the runner part between every two relative vertical slots has horizontal through hole, all push rod is placed with in each horizontal through hole, be provided with in each vertical slots and scrape plate.The utility model structure is simple, compact, and the little but discharge capacity of volume is large, easy to assembly, is adapted to the less and occasion that displacement requirements is large of volumetric spaces; Scrape plate to be connected with push rod mechanical, rely on rotary centrifugal force, all the time with lumen contact, effectively reduce leakage rate, measuring accuracy is improved.
Description
Technical field
The utility model relates to flowmeter technology field, particularly relates to a kind of inner cam type blade flowmeter.
Background technology
Blade flowmeter, due to features such as its measuring accuracy is high, smooth running, flow large, sand controls, is widely used in the departments such as oil, chemical industry, traffic, business, is specially adapted to measure crude oil, residual oil etc.
Common blade flowmeter is Double-casing, evagination wheeled construction.Flowmeter mainly comprises: shell body, inner housing, and both are connected by hex bolts, and inner housing is built with block, axis is placed in inner housing center, it installs external cam, and scraper plate is arranged in the groove of rotor case, by ball bearing and the cam contact of installation.
After liquid enters inner housing, drive rotor housing into rotation, thus drive scraper plate to rotate, and the bearing on scraper plate rolls on cam positive camber, simultaneously along with cam curve change, and telescopic moving in the groove of rotor case.Adjacent block scraper plate and rotor case and inner housing surround the sector region formed and are metered volume.
Though inner and outer shell structure can make flowmeter discharge capacity large, can the advantages such as elevated pressures be born, but it also has shortcoming: one, complex structure, parts are many, easily produce cumulative errors and cause assembling difficulty; Two, volume is comparatively large, needs to take up room compared with other volumeters greatly, has requirement to space, erecting stage; Three, critical piece processing difficulties, process equipment configuration and performance requirement higher; Four, the vertical installation of flowmeter, and scraper plate is required to be one-piece construction, therefore material is selected single, and be aluminum alloy material, corrosion resistance is incomplete.Therefore, this kind of structure is usually used in caliber metal blade flowmeter, and metering oil product is in the majority, and price is higher.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of inner cam type blade flowmeter.
The utility model is achieved through the following technical solutions:
A kind of inner cam type blade flowmeter, include housing, the inner chamber of housing is cam face, two opposed, the outside of housing is respectively equipped with liquid-inlet and liquid outlet, upper cover and lower cover is fixed with respectively at the upper and lower side of housing, upper cover, lower cover and housing cavity form measurement chamber, in the inside of measurement chamber, runner is installed, axis is provided with in the middle of runner, the top and bottom of described axis be rotatably installed in respectively upper cover and under cover, runner along the circumferential direction has four vertical slots uniformly, the upper and lower side of the runner part between every two relative vertical slots has horizontal through hole, all push rod is placed with in each horizontal through hole, be provided with in each vertical slots and scrape plate, the two ends of described push rod contact respectively scrapes plate in the vertical slots corresponding with it, in the upper end of axis, interior magnet steel is installed, in the outside of interior magnet steel, outer steel is installed, outer steel is provided with connector.
Runner cylindrical and housing cavity, scrape plate and form airtight measurement chamber.After liquid enters inner chamber, promoting driven by rotating wheel and scrape plate along the rotation of cam ring curve, scraping plate by moving as horizontal reciprocating in the groove acting on runner of push rod simultaneously.Be discrete item owing to scraping plate, in rotation process, by centrifugal action, the end face scraping plate contacts with housing cavity all the time.
The utility model has the advantages that: the utility model structure is simple, compact, the little but discharge capacity of volume is large, easy to assembly, is adapted to the less and occasion that displacement requirements is large of volumetric spaces; Scrape plate to be connected with push rod mechanical, rely on rotary centrifugal force, all the time with lumen contact, effectively reduce leakage rate, measuring accuracy is improved; Scraping plate is single-piece, can make metal material or graphite material easily, can meet the measuring requirement of different Korrosionsmedium.
