Abstract
The invention discloses a high-precision flow meter which comprises a flow meter main body and a high temperature-resisting open channel, wherein the high temperature-resisting open channel is mounted in a metering pipeline of the flow meter main body; the flow meter main body is composed of a cold rolled steel and a polypropylene resin on the surface of the cold rolled steel; according to the weight percentage, the content of the cold rolled steel is 90-85% and the content of the polypropylene resin is 5-10%; the high temperature-resisting open channel is formed by fusing stainless steel, chromium and nickel; according to the weight percentage, the content of the stainless steel is 39-50%, the content of chromium is 27-33% and the content of nickel is 23-28%. In such a mode, the high-precision flow meter can accurately calculate the flow under a high temperature condition, the error of flow calculation caused by the open channel under the influence of temperature is avoided and the use of a user is convenient.
Description
Technical field
The present invention relates to Hydraulic Field, particularly a kind of high precision flow.
Background technology
Metering is industrial eyes.Flow metering is one of ingredient of measuring science technology, and it and national economy, national defense construction, scientific research have close relationship.Carry out this work; to ensureing product quality, enhance productivity, the development of the technology that advances science all has important effect; particularly in energy crisis, current era that industrial production automation degree is more and more high, the role and effect of flowmeter in national economy is more obvious.The open channel of the flowmeter used in prior art mostly and flowmeter bodies be structure as a whole, use material is identical, the flowmeter material used in prior art is various, and can not effectively measure for the flowmeter under some high-temperature conditions, result of use is not good enough.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of flow that can calculate accurately under high-temperature condition, avoids open channel Yin Wendu to affect and flow meter is calculated and produced deviation, simultaneously user-friendly.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high precision flow, comprise: flowmeter bodies and high temperature resistant open channel, described high temperature resistant open channel is arranged in the metering pipeline of flowmeter bodies, described flowmeter bodies adopts the acrylic resin composition on cold-rolled steel and cold-rolled steel surface, according to percentage by weight proportioning: the content of described cold-rolled steel accounts for 90-95%, the content of described acrylic resin accounts for 5-10%, described high temperature resistant open channel is by stainless steel, chromium and nickel melting form, according to percentage by weight proportioning: described stainless content accounts for 39-50%, the content of described chromium accounts for 27-33%, the content of described nickel accounts for 23-28%.
In a preferred embodiment of the present invention, in described flowmeter bodies, the concrete proportioning of composition is: the content of described cold-rolled steel accounts for 91%, and the content of described acrylic resin accounts for 9%.
In a preferred embodiment of the present invention, in described high temperature resistant open channel, the concrete proportioning of composition is: described stainless content accounts for 48%, and the content of described chromium accounts for 28%, and the content of described nickel accounts for 24%.
In a preferred embodiment of the present invention, the diameter of described high temperature resistant open channel is 2-4mm.
The invention has the beneficial effects as follows: the present invention can calculate the flow under high-temperature condition accurately, avoid open channel Yin Wendu to affect and flow meter calculates generation deviation, simultaneously convenient for users to use.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
