Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to explain the technical solution of the present invention, the following description is made by using specific examples.

Fig. 1 shows a structure of a pitot tube portable tool for measuring a gas flow according to an embodiment of the present invention, and only parts related to the embodiment of the present invention are shown for convenience of description.

As shown in fig. 1-4, the portable frock of pitot tube of measurement gas flow that this embodiment provided includes pitot tube 1, erection joint and crossover sub 2, the erection joint is including connecting cap 3 and connecting main part 4, it has the internal thread to connect 3 bottoms of cap, the external screw thread has all been seted up at both ends about connecting main part 4, the erection joint is still including installing in the inside sealing member 8 of erection joint, the internal thread has been seted up at crossover sub 2 top, and the external screw thread has been seted up to crossover sub 2 bottom, connects the internal thread of 3 bottoms of cap and connects the external screw thread phase-match of main part 4 upper end, connects the external screw thread of main part 4 lower extreme and the internal screw thread phase-match at crossover sub 2 tops, pitot tube 1 passes from last to down in proper order connect cap 3, connect main part 4, crossover sub 2 and stretch into to survey in the pipeline.
