Abstract
The utility model discloses an oval gear flowmeter and aims to provide an oval gear flowmeter which is long in service life and high in measurement accuracy. The oval gear flowmeter comprises a housing which is provided with an inlet and an outlet. The oval gear flowmeter is characterized in that a pair of mutually engaged oval gears are coupled inside the housing, a permanent magnet is arranged on a gear coupling part, and a sensor is arranged in the lower part of the housing. The gears are made of PPS materials. The oval gear flowmeter is mainly used for measurement of fluid flow.
Description
Technical field
The utility model relates to a kind of flowmeter, relates in particular to a kind of oval gear flowmeter.
Background technology
Oval gear flowmeter claims again the discharge capacity flowmeter, belongs to volumeter a kind of, is the higher class of precision in flow instrument.It utilizes the mechanical measurement element that fluid continuously is divided into single known volume part, one by one, repeatedly is full of and the number of times that discharges this volume segment fluid flow comes measuring flow volume total amount according to measuring room.And its most metals that use of existing oval gear flowmeter are as gear material, in use metal and measuring chamber metallic walls rub and easily cause serviceable life too short, the accuracy of measuring reduces as time goes by, and moving component room machine frictional resistance is large, pressure difference is excessive, measures not accurate enough and stable.
Summary of the invention
The utility model discloses a kind of oval gear flowmeter, in order to solve the deficiencies in the prior art.
For addressing the above problem, technical solution of the present utility model is:
A kind of oval gear flowmeter comprises housing, is provided with import, outlet on the housing, it is characterized in that: a pair of intermeshing oval gear is housed in the described housing, and gear one end is provided with permanent magnet, and the bottom of housing is provided with inductor.
Gear is made by the PPS material.
The beneficial effects of the utility model are: by above-mentioned setting, in use by the rotation of permanent magnet so that inductor is corresponding responds to, measure accurately, and the gear that uses the PPS material to make can reduce the Metal Contact between gear and measuring chamber, has prolonged serviceable life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic cross-section of the present utility model;
Among the figure: 1-housing, 11-import, 12-outlet, 2-gear, 3-permanent magnet, 4-inductor.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Referring to accompanying drawing, the utility model comprises housing 1, is provided with import 11, outlet 12 on the housing 1, it is characterized in that: a pair of intermeshing oval gear 2 is housed in the described housing 1, gear 2 one ends are provided with permanent magnet 3, and the bottom of housing 1 is provided with inductor 4.
Gear 2 is made by the PPS material.
To be installed on by the oval gear flowmeter that the utility model is produced in practice and reserve the installation site, after installing import 11 places being connected water inlet (fluid) manages, export 12 places and connect water outlet (fluid) pipe, valve in the opening conduits makes liquid flow, two elliptic gears, 2 intermeshing drivings under according to the effect of fluid pressure difference at import 11 places and outlet 12 places, and respectively pivot, thereby the rotation by gear 2 continuously will riddle in the measuring chamber fixedly fluid and discharge one by one, by the Hall effect of 3 of inductor 4 and permanent magnets, thereby measure the accumulated value that sensed gear 2 revolutions draw fluid flow.
Above-mentioned embodiment is preferred embodiment of the present utility model; can not limit the utility model; other any change that does not deviate from the technical solution of the utility model and make or other equivalent substitute mode are included within the protection domain of the present utility model.
