Description
Technical field
The present invention relates to a kind of flowtube and molectron, particularly relate to a kind of flowtube for metering and assembly.
Background technology
Along with social development and the progress of science and technology, people are for environmental protection and energy-conservation further pay attention to, and the energy the most used in everyday, such as electricity, water, the energy-conservation of combustion air and heat play the most important role, and energy-conservation premise is the accurate measurement for the energy.
For the metering of fluid, such as water, heat, combustion gas etc., the development of measuring instrument has been subjected to the long period, from initial mechanical type instrument half machinery half-electron finally, purer electronic type till now.For fluid metering, ultrasonic flowmeter is the new product grown up in recent years, the features such as it is the most easy to wear, crushing is little are increasingly subject to pursuing of industry, but, ultrasonic flowmeter still suffers from various problem technically and needs solution badly at present, and such as precision is the highest, stability is the best.As shown in Figure 1, schematic diagram for the core component ultrasonic flow sensor of the ultrasonic flowmeter in the middle of prior art, a pair ultrasonic transducer is arranged on metal section, its ultrasound wave launched of transducer being in emission state reflects on reflector, through sound channel, then the reflector of the other end is arrived, it is re-reflected into the transducer for the state of reception, the ultrasonic flowmeter of this structure generally exists that precision is the highest, poor stability, therefore, these problems are solved in the urgent need to a kind of new technology.
Summary of the invention
The present invention is contemplated to solve above-mentioned precision problem, and can also improve stability further.Flowtube is the important composition parts of ultrasonic flowmeter, it it is the primary source measuring signal, the stability in the i.e. flow field of fluid characteristic in flowtube directly influences the stability measuring signal, find through analysing in depth, there is bigger problem in structure of the prior art, one is that the highest meeting of processing technique precision of metal section causes this to the locating bias of transducer in relatively high tolerance scope, impact produces precision and efficiency, two be ultrasound wave propagate in the passage of metal inner surface be easily subject to interference, three is that the interference rejection ability in flow field is poor, the most easily there is turbulent flow, whirlpool etc..
nullThe present invention devises a kind of high accuracy、The ultrasonic flow tube of high stability and assembly thereof，Its technical scheme is characterized by，The embedded ultrasonic flow tube of metal section，This flowtube is integrated，I.e. it is integrated with water inlet、Outlet、Transducer installing hole、Temperature sensor fixing hole、Reflector mounting groove is in the structure of one，The material of this integrated flowtube is plastics or pottery，This design can significantly improve the precision of metering，Simultaneously，At the two ends of flowtube, the reflector that interference rejection ability is strong is set，For this，Devise the reflector of water conservancy diversion chip，This flow deflector is positioned at cross section, flow field center position，When so fluid enters flowtube，Fluid can be divided into uniform two halves by flow deflector，Even if there is turbulent flow in upstream、Whirlpool，The existence of flow deflector also can largely reduce turbulent flow and whirlpool，Especially，The present invention have also been devised a kind of special reflector，The most bullet-nose reflector，This reflector takes full advantage of hydrodynamics and principle of dynamics，Reach to significantly improve turbulence effect，Thus improve the stability of metering.It addition, the design of the metal section of the present invention embedded integral type flowtube, also make that parts are less, assembly technology is simpler and convenient, significantly improve production efficiency.
The present invention solves the technical problem that prior art runs into, it is applicable to fluid metering instrument, it is particularly suited for ultrasonic flowmeter, the medium wherein circulated is the one in water, heating installation or combustion gas, such as ultrasonic water meter, ultrasonic calorimeter, ultrasound wave gas meter etc., significantly improve certainty of measurement and the stability of ultrasonic flowmeter so that ultrasonic flowmeter is possibly realized in industry, business, the large-scale application in the field such as civilian, military.
