Abstract
The utility model discloses improved gas turbo flow meter, this flowmeter comprises housing (1), test bar (2), signal panels (3), impeller (4) and gland (6), in the chamber that housing (1) and gland (6) are formed, test bar (2) is installed, signal panels (3) and impeller (4), be positioned at gas access place in the front portion of impeller (4) and spiral rectifier (5) is installed, spiral rectifier (5) comprises circular baffle (7) and spiral straightening vanes (8), wherein circular baffle (7) and spiral straightening vanes (8) are monoblock cast, form spiral rectifier.The utility model structure is simple, easy to install, appoints so have high-precision measurement effect at low discharge and when having complicated cyclone.
Description
Technical field
The utility model relates to flowmeter, is specifically related to a kind of improved gas turbo flow meter.
Background technology
Gas turbine meter is a kind of velocity flowmeter, and it has, and the pressure loss is little, precision is high, initial-flow is low, range ratio is large, antidetonation and the feature such as anti-Pulsating Flow performance is good.The type product is widely used in the fields such as oil, chemical industry, electric power, Industrial Boiler, gas pressure regulating station, transmission & distribution gas pipe network natural gas, city natural gas, and is widely used in Trade Measures.Europe and U.S.'s gas turbine meter be the natural gas measuring instrument being only second to orifice flowmeter.
No matter air turbine flowmeter plays irreplaceable effect in daily life or commercial production, but old-fashioned turbo flow meter when having complicated cyclone, an air-flow in low discharge or pipeline, wheel speed can be caused uneven, affect the signals collecting of signal panels and test bar, to such an extent as to there is the problems such as detection signal is unstable, signal fluctuation is large, even can affect the serviceable life of flowmeter, these shortcomings are fatal for requiring to measure accurately, flowmeter that environment for use is severe.
Summary of the invention
The purpose of this utility model is: propose a kind of improved gas turbo flow meter, and structure is simple, easy to install, appoints so have high-precision measurement effect at low discharge and when having complicated cyclone.
Technical solution of the present utility model is: this flowmeter comprises housing, test bar, signal panels, impeller and gland, in the chamber that housing and gland are formed, test bar, signal panels and impeller are installed, it is characterized in that: be positioned at gas access place in the front portion of impeller and spiral rectifier is installed, spiral rectifier comprises circular baffle and spiral straightening vanes, and on circular baffle, monoblock cast spiral straightening vanes forms spiral rectifier.
The utility model has the following advantages: the inside entering flowmeter 1, allowing gas uniform rotate, the gas of complicated cyclone hits on circular baffle, what rotated by gas uniform is diffused between spiral straightening vanes, by spiral straightening vanes, gas is shunted rotation by force; 2, small-flow gas is rotated by the compression of spiral rectifier, increases flow velocity, compresses postrotational gas and directly impact on impeller, improves the sensitivity of signal reflection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the spiral rectifier schematic diagram of Fig. 1.
in figure: 1 housing, 2 test bars, 3 signal panels, 4 impellers, 5 spiral rectifiers, 6 glands, 7 circular baffles, 8 spiral straightening vaness.
Embodiment
As shown in Figure 1, 2, this flowmeter comprises housing 1, test bar 2, signal panels 3, impeller 4 and gland 6, in the chamber that housing 1 and gland 6 are formed, test bar 2, signal panels 3 and impeller 4 are installed, it is characterized in that: be positioned at gas access place in the front portion of impeller 4 and spiral rectifier 5 is installed, spiral rectifier 5 comprises circular baffle 7 and spiral straightening vanes 8, and on circular baffle 7, monoblock cast spiral straightening vanes 8 forms spiral rectifier.
During installation, spiral rectifier 5 is arranged on the air intake of flowmeter shell 1 by gland 6, the gas of complicated cyclone makes it impact evenly and rapidly on impeller 4 by compression, shunting, rotation, impeller 4 rotates uniformly, produced by the signal panels that are attached thereto 3 and test bar 2 and respond to, last signal feedback is to terminal.
