Description
Technical field
The utility model relates to a kind of single-blade type target type meter, and it is mainly used in the data on flows of measuring fluid, substitutes original known target type meter, belongs to the measuring apparatus of the measurement fluid flow of architecture advances.
Background technology
At present, the device construction of known target type meter is to be made of a flow target plate, the weight that resets, rocking arm, connecting rod, back-moving spring, sensor etc.When target plate inserts detected fluid, fluid flows and clashes into target plate plate face, target surface is put along on the flow direction with rocking arm, be of the increase of effective bump target plate area of target surface and detected fluid with the detected fluid flow velocity, effectively bump target plate area is unfixing for it, area progressively reduces when putting on the target surface, otherwise increases.After the bigger fluid of viscosity flows through target plate, because the characteristic of fluid, behind target plate, produce vortex, after making easily that solid particle adheres in the fluid, being deposited on target plate, constantly destroy the former design balance of target plate, so present known target type meter exists, and measure linear is bad, error big, it is frequent to safeguard, problems such as bad measurement repeatability.
Summary of the invention
The purpose of this utility model be to overcome existing target type meter exist that measure linear is bad, error is big, difficult in maintenance, problems such as bad measurement repeatability, a kind of aerofoil profile target type meter is provided, this target type meter can not only keep the advantage that present target type meter is simple in structure, maintenance cost is low, can also ensure the continuous coverage good linearity, error is little, measuring repeatability good.
The utility model adopts following technical scheme, it is a kind of single-blade type target type meter, by target plate, axle and axle sleeve, front arm, rear arm, substrate, connecting rod, sensor rotating disk and sensor constitute, it is characterized in that target plate is a slice aerofoil profile plate, aerofoil profile plate middle part and the anterior lower end that is connected rear arm and front arm respectively with axle and axle sleeve, front arm is longer than rear arm, the rear arm upper end is connected with axle sleeve with axle with substrate, from the front arm lower end to the front arm stage casing perforate of rear arm equal in length position, with axle and axle sleeve front arm is connected on the substrate, front arm upper end, substrate top connects connecting rod one end, the connecting rod other end is connected with sensor rotating disk on the substrate, and the sensor rotating disk connects sensor.
The aerofoil profile plate is connected forward and backward rocking arm and substrate by axle and has constituted movably parallelogram with axle sleeve.
Above-mentioned connection is to be made by the high molecular polymerization high-abrasive material with axle with axle sleeve.
Wing-shaped plate can be made by adding counterweight in the hollow glass steel or stainless steel housing.
The utility model changes the common tabular target plate of target type meter into the single-blade template, continuity principle and Bernoulli's theorem according to air-flow can be learnt, the fly wing to wing pressure of template below of the pressure of aerofoil profile plate top is little, that is to say, aerofoil profile plate lower surface be subjected to the upwarding pressure template upper surface of flying wing to wing is subjected to downward pressure and wants big, this pressure differential just makes the aerofoil profile plate produce lift, and the aerofoil profile plate can steadily rise or decline along with the increase of fluid to be measured flow velocity or minimizing like this; And the aerofoil profile plate is connected with substrate by rotating shaft, rocking arm, so the cross-sectional area over against direction of flow remains unchanged when limiting the aerofoil profile plate and rising in fluid or descend.
The compound sticking thing wear-resistant coating of surface-coated one deck of this aerofoil profile plate, the slick and sly abundant guide vane template trailing edge convergence of aerofoil profile plate leading edge is the aircraft wing shape along the cross section of detected fluid flow direction.
The aerofoil profile plate is in fluid, and fluid flows through each position, back, surface and do not produce vortex, adds washing away when fluid flows, and effectively solid particle adheres to, deposits on the aerofoil profile plate in the eliminate fluid; The aerofoil profile plate all is immersed in the detected fluid in addition, not influenced by the flow surface surge.
Realize that by such scheme suspended particle adheres to, deposits the measuring error that produces in the continuous linear measurement of target type meter, minimizing surge, the fluid, ensure that measuring repeatability is good.
