Description
Technical field
The utility model is related to a kind of sliceable Pitot tubes, can make full use of in sorts of systems such as ventilation, air-conditioning, smoke evacuations
Wind speed, during air quantity Site Detection, belong to experiment test technical field.
Background technology
Pitot tube is that a kind of borrow measures the difference of fluid gross pressure and static pressure to calculate the important instrument of flow velocity.Pitot tube
When measuring pipe fluid pressure, Pitot tube need to be inserted into certain depth in pipeline.When measuring the pipeline of different inner diameters, skin
The insertion depth of trustship is also different.But existing Pitot tube is typically all to be processed into a certain regular length, enables the Pitot tube only
The pipeline that caliber is less than Pitot tube length can be measured, it is limited to measure caliber.To measure the pipeline of Large Diameter Pipeline, then Pitot tube is required
Length it is very long, this can be such that the difficulty of processing of Pitot tube improves, while the carrying of Pitot tube is also inconvenient.
Invention content
The technical problems to be solved in the utility model is：Provide it is a kind of it is simple in structure, easy to carry, use scope is flexible
Sliceable Pitot tube, when solving the pipeline for measuring Large Diameter Pipeline, the difficulty of processing of Pitot tube is high, the carrying of Pitot tube not side
Just the problem of.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is there is provided a kind of sliceable Pitot tube,
It is characterised in that it includes Pitot tube pressure measurement section, Pitot tube pressure measurement section passes through the interior extension that can increase length and outer extension
It is connect with Pitot tube nozzle belt.
Preferably, one end of the Pitot tube pressure measurement section is equipped with pressure measurement section total head interface and pressure measurement section static pressure interface, skin
One end of trustship nozzle belt is equipped with nozzle belt total head interface and nozzle belt static pressure interface, and interior extension one end connects with pressure measurement section total head
Mouth connection, the interior extension other end are connect with nozzle belt total head interface, and outer extension one end is connect with pressure measurement section static pressure interface, outside
The extension other end is connect with nozzle belt static pressure interface.
Preferably, the both ends of the interior extension and outer extension are equipped with hickey, interior extension one end and survey
Pressure section total head interface is connected through a screw thread, and the interior extension other end is connected through a screw thread with nozzle belt total head interface, outer extension
One end is connected through a screw thread with pressure measurement section static pressure interface, and the outer extension other end is connected through a screw thread with nozzle belt static pressure interface.
Preferably, it is equipped with circle elastic washer on the interior extension and the hickey at outer extension both ends.
Compared with prior art, the utility model has the advantages of simple structure, use scope is flexible, by the quantity for increasing and decreasing extension
The length of Pitot tube is adjusted, not only makes the measurable caliber range for expanding Pitot tube, is also grasped convenient for experiment compared with traditional design
Make the carrying and use of personnel.

Fig. 2 is a kind of fractionation schematic diagram of sliceable Pitot tube；
Fig. 3 is a kind of installation diagram of sliceable Pitot tube.
Specific implementation mode
To make the utility model be clearer and more comprehensible, hereby with preferred embodiment, and attached drawing is coordinated to be described in detail below.
The utility model is a kind of sliceable Pitot tube, as shown in Figure 1 comprising a root skin trustship pressure measurement section 1, several
Extension 2 in root, several outer extensions 3, a root skin trustship nozzle belt 4.The both ends of interior extension 2 and outer extension 3 are all provided with
There is hickey.Pitot tube pressure measurement section 1 is by that can increase the interior extension 2 and outer extension 3 and Pitot tube nozzle belt 4 of length
Connection.
As shown in Fig. 2, one end of Pitot tube pressure measurement section 1 is equipped with pressure measurement section total head interface 1-1 and pressure measurement section static pressure interface 1-
2, one end of Pitot tube nozzle belt 4 is equipped with nozzle belt total head interface 4-1 and nozzle belt static pressure interface 4-2, interior extension 2 and extension
Circle elastic washer 5 is equipped on the hickey at 3 both ends of long section.
As shown in figure 3, when Pitot tube provided by the utility model measures pressure, 2 one end of interior extension is surveyed with Pitot tube
The total head interface 1-1 of pressure section 1 is connected through a screw thread, and 2 other end of interior extension and the total head interface 4-1 of Pitot tube nozzle belt 4 are logical
Cross threaded connection.3 one end of outer extension and the static pressure interface 1-2 of Pitot tube pressure measurement section 1 are connected through a screw thread, and outer extension 3 is another
One end and the static pressure interface 4-2 of Pitot tube nozzle belt 4 are connected through a screw thread.In assembling process, interior extension 2 and outer extension 3
It is respectively arranged with a circle elastic washer 5 on the hickey at both ends, so that interface is sealed using elastic washer 5 after being screwed so as to screw thread.
When measuring the pipeline of Large Diameter Pipeline, if Pitot tube pressure measurement section 1, Pitot tube nozzle belt 4, interior extension 2 and outer extension
Length after 3 connection of section will be in multistage then by the quantity of extension in increase by 2 and outer extension 3 less than tested pipeline diameter
Extension 2 splices successively, and extension outside multistage 3 is spliced successively, then is connect by preceding method and Pitot tube pressure measurement section 1, Pitot tube
Pipeline section 4 splices.Spliced Pitot tube is set to measure the pressure value away from the farthest measuring point of pipeline pressure tap.
