Abstract
The utility model provides an anti-leak wind speed measuring apparatus for a gas-solid two-phase flow, comprising a ball valve arranged on a gas-solid two-phase flow pipeline, a circular sealing device and a shield type speed measuring pipe, wherein, the circular sealing device and the shield type speed measuring pipe are tightly connected together, and connected with the ball valve by a screw. The anti-leak wind speed measuring apparatus for the gas-solid two-phase flow, provided by the utility model, can realize the air quantity measurement in a gas-solid two-phase flow device in a simple and no-leak way.
Description
Technical field
The utility model relates to the Dual-Phrase Distribution of Gas olid fields of measurement, and is particularly related to a kind of anti-leak wind speed measuring device that is used for Dual-Phrase Distribution of Gas olid.
Background technology
Dual-Phrase Distribution of Gas olid is prevalent in the spontaneous phenomenon, and relates to a lot of fields of national product, with industrial and agricultural production close ties is arranged.Because the channelization of solid material is carried and to be had the conevying efficiency height, avoid environmental impact, increases advantage such as security, so it becomes the relevant the closest application with industrial and agricultural production of Dual-Phrase Distribution of Gas olid, and the pipeline transportation that is widely used in coal dust in the thermal power generation, the pipeline transportation of flour in the food industry, the pipeline transportation of medicine during medicine is made, the pipeline transportation of industrial chemicals etc. in the pipeline transportation of ore and the chemical industry in the metallurgical industry.Just because of this, the research of relevant Dual-Phrase Distribution of Gas olid is subjected to increasing attention.The pipeline gas fixed double phase flow is a kind of common physical phenomenon in engineering, and for example wind powder feeding pipes of power plant is exactly Dual-Phrase Distribution of Gas olid.
Yet the Dual-Phrase Distribution of Gas olid device that malleation is carried generally is connected to by pressurized air and supporting packoff thereof and guarantees that silently solid phase particles is not revealed in the measuring process on the pipeline in environment when carrying out measuring wind speed.This needs to connect blowing plant in the test at the scene, and silently also can't prevent the solid phase particles ejection of its inner product in the moment of opening, and operating personnel's workload is big, and site environment is also comparatively abominable.
The utility model content
The utility model proposes a kind of anti-leak wind speed measuring device that is used for Dual-Phrase Distribution of Gas olid, its air measuring in can simple leak free realization Dual-Phrase Distribution of Gas olid device.
In order to achieve the above object, the utility model proposes a kind of anti-leak wind speed measuring device that is used for Dual-Phrase Distribution of Gas olid, comprising:
Ball valve is arranged on the Dual-Phrase Distribution of Gas olid pipeline;
Annular seal and shield formula pitot tube, wherein, described annular seal and shield formula pitot tube closely link together, and by being threaded onto on the ball valve.
Further, described ball valve has regulating device, is used for opening or closing the ball valve opening.
Further, described shield formula pitot tube has carriage, is used to control described shield formula pitot tube and passes in and out ball valve by annular seal.
The anti-leak wind speed measuring device that is used for Dual-Phrase Distribution of Gas olid that the utility model proposes adopts the cooperation of ball valve, annular seal and shield formula pitot tube, the air measuring in can simple leak free realization Dual-Phrase Distribution of Gas olid device.This device need not to use pressurized air, and is simple to operate, and also very little to the pollution of environment.
Description of drawings
Figure 1 shows that the anti-leak wind speed measuring device structural representation that is used for Dual-Phrase Distribution of Gas olid of the utility model preferred embodiment.
Embodiment
In order more to understand technology contents of the present utility model, especially exemplified by specific embodiment and cooperate appended graphic being described as follows.

Please refer to Fig. 1, Figure 1 shows that the anti-leak wind speed measuring device structural representation that is used for Dual-Phrase Distribution of Gas olid of the utility model preferred embodiment.The utility model proposes a kind of anti-leak wind speed measuring device that is used for Dual-Phrase Distribution of Gas olid, comprising: ball valve 20 is arranged on the Dual-Phrase Distribution of Gas olid pipeline 10; Annular seal 30 and shield formula pitot tube 40, wherein, described annular seal 30 and shield formula pitot tube 40 closely link together, and by being threaded onto on the ball valve 20.
According to the utility model preferred embodiment, described ball valve 20 has regulating device 21, is used for opening or closing ball valve 20 openings.Described shield formula pitot tube 40 has carriage 41, is used to control described shield formula pitot tube 40 by annular seal 30 turnover ball valves 20.
The utility model is made up of a ball valve 20 and a supporting annular seal 30 and shield formula pitot tube 40 of being installed on the Dual-Phrase Distribution of Gas olid pipeline 10, annular seal 30 and shield formula pitot tube 40 make up closely and connect together, and by being threaded onto on the ball valve 20.Open ball valve 20 by regulating device 21 during use, and push shield formula pitot tube 40 by carriage 41, annular seal 30 guarantees that solid particle is not to external leakage.
The anti-leak wind speed measuring device that is used for Dual-Phrase Distribution of Gas olid that the utility model proposes adopts the cooperation of ball valve, annular seal and shield formula pitot tube, the air measuring in can simple leak free realization Dual-Phrase Distribution of Gas olid device.This device need not to use pressurized air, and is simple to operate, and also very little to the pollution of environment.
Though the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Have in the technical field under the utility model and know the knowledgeable usually, in not breaking away from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is as the criterion when looking claims person of defining.
