Abstract
The utility model discloses a scraper type flow meter with a magnetic adsorption structure. The scraper type flow meter comprises an outer shell which comprises a barrel, a feeding pipe and a discharging pipe, wherein the two ends of the barrel are closed; the feeding pipe and the discharging pipe are integrally formed with the barrel and are symmetrically distributed; a pointed cone-shaped plate facing to one side of the feeding pipe is arranged between the feeding pipe and the discharging pipe; a rotating drum tightly glued to the sharp-pointed plate is arranged at the center of the barrel; a crossing-shaped supporting frame is arranged at the center of the rotating drum; each supporting foot of the supporting frame is of circular tube shape; a scraper blade is sleeved in each circular tube; a spring is arranged between each circular tube and the bottom of the corresponding scraper blade; one ends of the scraper blades are resisted against the springs while the other ends are glued to an inner wall of the barrel; each scraper blade is arranged as a plate with an arch-shaped cross section; a magnet made of a composite material and a durable lining are successively arranged at the front end of each plate. According to the utility model, the springs are arranged between the crossing-shaped supporting frame and the scraper blades, and the scraper blades are flexibly pushed by the springs, so that the structure component is reduced. and the cost is lowered; through the scraper blade, the sealing tightness, the wear-resisting property and the impact resistance of a metering chamber are increased.
Description
technical field:
The utility model relates to flowmeter process technology, relates in particular to a kind of scraper type flowmeter with magnetic absorption structure.
background technology:
Blade flowmeter, when detected fluid is by the inlet streams inbound traffics timing of flowmeter, produces a pressure reduction between the entrance and exit of flowmeter, and this pressure reduction promotes scraper plate and rotor rotates.Rotor often turns around and just discharges a certain amount of fluid, thereby obtains instantaneous delivery and integrated flow by the number of revolutions of calculating rotor.
Blade flowmeter is cam flight flowmeter mostly, and its structure is comparatively complicated, and manufacturing cost is high, easily damages, and maintenance is also relatively difficult.
Blade flowmeter also exists a defect can have influence on the degree of accuracy of flowmeter measuring room, be mainly due to adjacent scraper plate can not and flowmeter shell inwall between can not fully contact or contact not tight, cause the liquid meter precision in measuring room poor.
In addition, the structural design of scraper plate makes easily infringement in High Rotation Speed process, impact resistance and rub resistance power performance weakness, and serviceable life is short.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of scraper type flowmeter with magnetic absorption structure, and structural design novelty, has reduced manufacturing cost, has higher shock-resistant and crocking resistance.
The technical solution of the utility model is as follows:
With the scraper type flowmeter of magnetic absorption structure, comprise shell body, it is characterized in that: described shell body comprises the cylindrical shell of closed at both ends and integrated with it, symmetrical feed pipe and discharge nozzle, between described feed pipe and discharge nozzle, be provided with the sharp cone distal plate body towards feed pipe one side, the center of described cylindrical shell is provided with the rotating cylinder fitting tightly with sharp cone distal plate body, the center of rotating cylinder is provided with criss-cross bracing frame, each leg of bracing frame is tubular, in pipe, be set with scraper plate, between pipe and scraper plate bottom, be provided with spring, described spring is withstood in scraper plate one end, the inwall of the other end and cylindrical shell fits, described scraper plate adopts the plate body that cross section is arch, the front end of plate body is provided with the magnet of compound substance successively, anti-wearing liner.
The described scraper type flowmeter with magnetic absorption structure, is characterized in that: the right side wall of described sharp cone distal plate body is by epimere the streamline section that diminishing curved bend tune and hypomere and rotating cylinder outer wall fit and forms.
The utility model has the advantages that:
1, the utility model adopts between criss-cross bracing frame and scraper plate and is provided with spring, and spring, to the scraper plate promotion of stretching, has reduced construction package, has reduced cost;
2, the utility model structural design novelty, the magnet that has compound magnetic plastics to become by the plate body Front-end Design at scraper plate, the formation measuring room that contacts with flowmeter shell inwall fast in the process that guarantees stretching out at scraper plate, seals tight; The front end of plate body is also designed with anti-wearing liner, has improved anti-wear performance, has extended serviceable life; Plate body adopts domes, and arcuate surface towards entering metering liquid direction, has improved impact resistance in metering process, has extended serviceable life.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
With the scraper type flowmeter of magnetic absorption structure, comprise shell body, shell body comprises the cylindrical shell 1 of closed at both ends and integrated with it, symmetrical feed pipe 2 and discharge nozzle 3, between feed pipe 2 and discharge nozzle 3, be provided with the sharp cone distal plate body 4 towards feed pipe one side, the center of cylindrical shell 1 is provided with the rotating cylinder 5 fitting tightly with sharp cone distal plate body 4, the center of rotating cylinder 5 is provided with criss-cross bracing frame 6, each leg of bracing frame 6 is tubular, in pipe, be set with scraper plate 7, between pipe and scraper plate bottom, be provided with spring 8, the bottom that leg endoporus is withstood in scraper plate 7 one end, the inwall of the other end and cylindrical shell 1 fits, it is the plate body 7-1 of arch that scraper plate 7 adopts cross section, the front end of plate body 7-1 is provided with the magnet 7-2 of compound substance successively, anti-wearing liner 7-3, formation measuring room fast contacts with flowmeter shell inwall in the process that guarantees stretching out at scraper plate, seal tight, improved anti-wear performance simultaneously.
The right side wall of sharp cone distal plate body 4 is by epimere the streamline section 4-2 that diminishing curved bend tune 4-1 and hypomere and rotating cylinder outer wall fit and forms, curved bend tune 4-1 keeps off the sliding streamline section 4-2 that transits to scraper plate, streamline section 4-2 and rotating cylinder 5 fit tightly, and guarantee that metering liquid can not affect from feed pipe to discharge nozzle the precision of metering.
