Abstract
The utility model discloses a kind of for dust pipeline wind speed, the Pitot tube of air volume test, which is characterized in that including T shape Pitot tube total pressure test tube, one end of the T shape Pitot tube total pressure test tube is connected with dust-exhausting port, and dust-exhausting port is equipped with dust-exhausting port cap.The utility model is provided by the way that total pressure test tube is connected with dust-exhausting port in the L shape elbow of Pitot tube, when Pitot tube is blocked due to dust accumulation, opens dust-exhausting port, dust accumulation is discharged, Pitot tube is enable to be used for dust pipeline wind speed, air volume test.Compared with prior art, technical solution structure provided by the utility model is simple, and Pitot tube is made to can be used for dust pipeline wind speed, air volume test, is also convenient for the use of experiment operator.
Description
Technical field
The utility model relates to a kind of Pitot tube for dust pipeline air volume test, can be used for divulging information, air-conditioning, smoke evacuation etc.
The wind speed of sorts of systems, air quantity on-site test process, wind speed, air quantity on-site test especially suitable for dust pipeline, belong to reality
Test the field of test technology.
Background technique
Pitot tube is a kind of important instrument that flow velocity is calculated by means of the difference of measurement fluid gross pressure and static pressure.Pitot tube
When measuring pipe fluid pressure, total pressure gaging hole is opposite with direction of flow, when Pitot tube is used for wind speed, the wind of dust pipeline
When measuring on-site test, inevitably part dust can enter in the total pressure test tube of Pitot tube from total pressure gaging hole, and accumulate in skin
The L shape elbow of trustship.As Pitot tube uses the increase of time, dust is gradually increased until that blocking total pressure is surveyed at this
Pipe causes Pitot tube to survey pressure failure.
Summary of the invention
The technical problem to be solved by the utility model is to after existing Pitot tube use can accumulation of ash inside it, very
To the problem of blocking.
In order to solve the above-mentioned technical problem, the technical solution of the utility model provide it is a kind of for dust pipeline wind speed,
The Pitot tube of air volume test, which is characterized in that including T shape Pitot tube total pressure test tube, one end of the T shape Pitot tube total pressure test tube
It is connected with dust-exhausting port, dust-exhausting port is equipped with dust-exhausting port cap.
Preferably, the dust-exhausting port is connected through a screw thread with dust-exhausting port cap.
The utility model is provided by the way that total pressure test tube is connected with dust-exhausting port in the L shape elbow of Pitot tube, works as Pitot tube
When due to dust accumulation blocking, dust-exhausting port is opened, dust accumulation is discharged, Pitot tube is enable to be used for dust pipeline wind speed, air volume test.
Compared with prior art, technical solution structure provided by the utility model is simple, and Pitot tube is made to can be used for dust-laden pipe
Road wind speed, air volume test are also convenient for the use of experiment operator.
Detailed description of the invention
Fig. 1 is the exploded view of Pitot tube provided by the utility model；
Fig. 2 is the structural schematic diagram of Pitot tube provided by the utility model；
Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
Embodiment
Such as the structural schematic diagram that Fig. 1,2 are Pitot tube provided by the utility model, the Pitot tube includes that T shape Pitot tube is complete
Test tube 1 is pressed, one end of T shape Pitot tube total pressure test tube 1 is welded to connect the dust-exhausting port 2 of threaded interface, and dust-exhausting port 2 is equipped with band spiral shell
The dust-exhausting port cap 3 of line interface.
When measuring pressure, dust-exhausting port 2 is connected through a screw thread with dust-exhausting port cap 3, and screwing seals Pitot tube.
In Pitot tube dust discharge, the dust-exhausting port cap 3 of threaded interface is unscrewed, by the product in "T"-shaped Pitot tube total pressure test tube 1
Dirt is discharged by the dust-exhausting port 2 of threaded interface.
