Abstract
The utility model discloses a volumetric flow meter, particularly a volumetric scrape flow meter, which is composed of a flow meter body, a connecting part and a meter head (indicator). In the casing of the flow meter body, a cylindrical metering cavity is eccentrically provided with a rotor of a cylinder. A rotor chute is provided with a scrape, and the geometric shape of the scrape is a part of the cylinder. The surface of the outer wall is provided with a plurality of toothed rectangular narrow grooves. The end face of the rotor is provided with a cylindrical flute. A thin wall circular moving ring with certain elasticity is arranged inside the flute.
Description
The utility model is about volumeter, the particularly improvement of volumetric scraper flowmeter, this flowmeter is made up of flowmeter main body, coupling part and gauge outfit (indicator), in the housing of its flowmeter main body, it is the rotor that axle is rotated that measurement chamber is equipped with the central shaft, the garden column casing of rotor radially has mutually at an angle of 90 four chutes six chutes of 60 ° of angles (or be mutually), is equipped with along the measurement chamber inwall to make the scraper plate that radially slides in chute.
For the fluid flow (as measuring the flow of various oil products) of measuring the flowmeter of flowing through, so far it is interference-free fully by measurement chamber the time still to be extensive use of a kind of fluid to be measured both at home and abroad, do not produce eddy current, do not change fluid flow pattern blade flowmeter (referring to China metering publishing house publish " flow measurement handbook, volumes such as Japanese river Tian Yulang).Cam-type or concave formula blade flowmeter as is well known, the pressure loss generally is no more than 0.3 kilograms per centimeter
2, measuring accuracy can reach ± and 0.2%, adaptability is strong, and vibration and noise are very little, help the advantage (referring to " the complete measuring instrument of crude oil " of the publication of Shanghai science tech publishing house, group is write in the complete metering of crude oil) of inspection and maintenance.But the cam flight flowmeter must rely on cam---the motion of the secondary guiding of roller scraper plate, and measurement chamber also must be made up of two different garden cylinders of radius size; Concave formula blade flowmeter then must have concave type measurement chamber to guide the motion of scraper plate.This gives further to make structure miniization and reduce cost and brings difficulty.In addition, the scraper plate of above-mentioned two kinds of structures and the gap between the measurement chamber are fixed values, and rigidity is bigger, block easily when wedging hard point.In order to overcome this shortcoming, reveal existing a kind of structure of utilizing elastic scraper to solve, but use elastic scraper to bring the new difficulty of selecting material and best clearance again.
The purpose of this utility model is that a kind of improved blade flowmeter will be provided, and it not only has the advantage of known blade flowmeter, and can further improve its reliability and simplified manufacturing technique, makes it to reduce cost and be convenient to microminiaturization, enlarges range of application.
Its solution is: the rotor that a Cylinder is installed in the measurement chamber of garden cylindricality prejudicially, in the equally distributed chute that rotor radially has, scraper plate is housed, its geometric configuration is the some of Cylinder, and the rotor outer wall surface is split into the narrow groove of rectangle of some dentations, rotor end-face has the groove of garden cylindricality, is installed with in this groove to have certain flexible thin-walled garden shape floating ring.
Like this, the modular construction of measuring room is oversimplified, the geometric configuration of main part is in addition oversimplified; Next is that the narrow groove of rectangle of some dentations of opening on the rotor outer wall surface has stoped leakage, and draws together away the particle of carrying secretly in the fluid; Secondly be to have certain flexible thin-walled garden shape floating ring the garden post inside surface of scraper plate and measurement chamber is fitted tightly again; And wedging is during hard point between scraper plate and measurement chamber, and scraper plate can be done suitable yielding, therefore, prevented stuck with reduced leakage.
The concrete device details and the working condition of this utility model are provided by following accompanying drawing.
Fig. 1 is the sectional view according to the floating ring blade flowmeter that the utility model proposes.
As shown in the figure, the measurement chamber (7) that a garden cylindricality is arranged in the housing (1), measurement chamber (7) can be the structure of an integral body with housing (1), also can be other embedded structure of branch, so that the flowmeter of different sizes adopts different material and different process for treating surface.A rotor (5) has been installed in measurement chamber (7) prejudicially, and rotor (5) is fixed on armature spindle (3), and its two ends are by rolling bearing or sliding supported condition.Rotor (5) is a Cylinder, its Cylinder radially has mutually at an angle of 90 four chutes six chutes of 60 ° of angles (or be mutually), the scraper plate (2) that radially slides along measurement chamber (7) inwall work is housed in the chute, and its geometric configuration is the part of Cylinder.Scraper plate (2) selects for use suitable material to make, and also can or inlay high-abrasive material at top coating hard material.The Cylinder outer wall surface of rotor (5) has the narrow groove of rectangle (6) of some dentations, and two end faces of rotor (5) have the groove (8) of garden cylindricality, is installed with in its groove (8) to have certain flexible thin-walled garden shape floating ring (4).Floating ring (4) is freely controlled the scraper plate (2) of making telescopic slide along measurement chamber (7) inwall and is in normal operation position; Scraper plate (2) is then freely controlled the centre that floating ring (4) remains on measurement chamber (7).Floating ring (a 4) end face is therein loaded onto one, also can respectively load onto one at two end faces respectively.
After fluid enters measurement chamber (7) in the direction of arrows, promptly promote scraper plate (2) and be rotated in a clockwise direction and promote rotor (5) rotation, in the chute of scraper plate during work (2) on the rotor that is fixed on armature spindle (3) (5), make telescopic slide along measurement chamber (7) inwall.The fluid that flows into from inflow entrance is full of on one side by the inwall of measurement chamber (7), the periphery of rotor (5) and the space that scraper plate (2) is constituted, with rotor (5) rotation be sent to flow export on one side.Rotor (5) rotates a circle promptly to the fluid of four (or six) crescent volumes of flow export output, and the armature spindle (3) that is fixed with rotor (5) is the revolution of output rotor (5) then, drives instruction unit by gear mechanism, indication flow or send flow signal.
