Description
Technical field
The present invention relates to the cooling jacket of a kind of bi toba flow sensor, particularly a kind of bi toba flow sensor.
Background technology
Bi toba flow sensor is the flow sensor that designs according to the pitot tube principle that French scientist H.Pitot invents.Pitot tube claims Pitot tube again, and bar is pressure unit, and bi toba flow sensor is the sensing element that the principle of employing pitot tube measures fluid pressure difference.The predecessor of bi toba flow meter is the intelligent probe formula flowmeter of the Chinese professor Xu Xiangdong of Tsing-Hua University invention.
Bi toba flow sensor has straight tube shape connecting pipe, connecting pipe has joint flange outward, interior pipe is arranged in the connecting pipe, the upper end of connecting pipe is stretched out in the upper end of interior pipe, the upper end mouth of pipe of connecting pipe and interior pipe is respectively total head interface and static pressure interface, the lower end of connecting pipe is connected with the pressure head, and there are the pitot hole that links to each other with the inner chamber of connecting pipe and the baroport that links to each other with interior pipe in the lower end of pressure head.
During use, vertically insert the straight tube shape connecting pipe of bi toba flow sensor in the fluid-transporting tubing from the sidewall of pipeline, allow the center of pitot hole and baroport on the axis of pipeline, pitot hole is facing to the flow path direction that comes of fluid, and baroport is facing to the flow path direction that goes of fluid.When fluid flows in pipeline, at the total head interface of connecting pipe upper end and total head and the static pressure of static pressure interface difference output channel inner fluid, total head and static pressure with the fluid that flowing in the pipeline, in conjunction with the parameters such as temperature, density and pipeline section of fluid, calculate the flow of pipeline inner fluid with flow integrator by fluid mechanics principle.
The connecting pipe of bi toba flow sensor is to make with steel, this bi toba flow sensor can only not be to use under the very high operating mode in the temperature of fluid, when using under the fluid operating mode of bi toba flow sensor in high temperature or superhigh temperature, the mechanical property of connecting pipe sharply descends, the mechanical property decline of connecting pipe can cause the connecting pipe distortion, causes measuring inaccurate.In the prior art, there is not the bi toba flow sensor that can under the fluid operating mode of high temperature or superhigh temperature, use.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind of high temperature bi toba flow sensor that can under the fluid operating mode of high temperature or superhigh temperature, use.
The present invention is achieved using the following method.
The high temperature bi toba flow sensor has straight tube shape connecting pipe, interior pipe is arranged in the connecting pipe, the upper end of connecting pipe is stretched out in the upper end of interior pipe, the upper end mouth of pipe of connecting pipe and interior pipe is respectively total head interface and static pressure interface, the lower end of connecting pipe is connected with the pressure head, there are the pitot hole that links to each other with the inner chamber of connecting pipe and the baroport that links to each other with interior pipe in the lower end of pressure head, the outside at connecting pipe is with jacket pipe, jacket pipe has joint flange outward, the jacket pipe upside has advancing of jacket pipe, outlet, the axis fluid media (medium) distributor pipe parallel with the axis of jacket pipe arranged in the jacket pipe, the upper end of fluid media (medium) distributor pipe links to each other with the import of chuck, has on the tube wall of fluid media (medium) distributor pipe along the uniform aperture of tube wall.
During installation, the connecting pipe that the outside is with jacket pipe vertically inserts in the fluid-transporting tubing from the sidewall of pipeline, allows the center of pitot hole and baroport on the axis of pipeline, and pitot hole is facing to the flow path direction that comes of fluid, and baroport is facing to the flow path direction that goes of fluid.
When the present invention uses under the fluid operating mode of high temperature or superhigh temperature, allow cooling fluid medium enter jacket pipe from the import of jacket pipe, cooling fluid medium elder generation incoming fluid dielectric distribution pipe, fluid media (medium) is uniform in jacket pipe through the fluid media (medium) distributor pipe, goes out to flow out from jacket pipe again.
There is jacket pipe in the outside of connecting pipe of the present invention, the fluid media (medium) distributor pipe is arranged in the jacket pipe, can be with the cooling fluid medium jacket pipe of flowing through during use, when under the fluid operating mode of high temperature or superhigh temperature, using, allow the temperature of connecting pipe can be not too high, keep the physical strength of connecting pipe not reduce, indeformable, guarantee to measure accurately.
Below in conjunction with accompanying drawing, the present invention is further described.
