Further, the kicker magnet fixinig plate is rare earth permanent magnet sheet metal.
Further, the static pressure tube and total head measurement pipe are stainless steel tube.
Compared with prior art, the utility model has the following advantages：
(1) it can rely on the magnetic absorption of fixinig plate on the measured hole of power plant's pulverized coal channel, plug sealing envelope is exempted from realization
It is stifled and exempt to fill in cloth positioning, be applicable to different tube diameters, different sealing form wind speed gaging hole, avoid conventional threads plug and lean on
Penstock face different gaging hole apertures or inside and outside silk difference shape when not general problem, while also evaded screw thread occur stripped thread,
Wear, get rusty equivalent damage when the installation problem brought.
(2) kicker magnet fixinig plate is threaded through by silica gel sealing ring on backing tube, and by fixing nut realize it is fixed and
Backing tube is fixed in a predetermined direction, avoids the occurrence of backing tube and disorderly shake the large error brought by sealing, prevents leakage from causing
Measuring wind speed is distorted, and greatly improves measurement efficiency.
(3) can according to the graduated scale in total head measurement pipe, by adjust fixing nut realize backrest length of tube adjusting and
Positioning, meets the measuring wind speed of different height wind speed gaging hole and different tube diameters pulverized coal channel, meanwhile, the design of unilateral graduated scale,
Convenient for distinguishing total head measurement pipe and static pressure tube, prevent human operational error.
(4) static pressure tube and the outlet of total head measurement pipe are designed as pagoda head, facilitate connection silicone tube.
(5) kicker magnet fixinig plate material is rare earth permanent magnet metal material, and kicker magnet fixinig plate has preferable mechanical performance, gently
Just durable, it is storing in transportational process, backrest pipe surface can be adsorbed in or multiple fixinig plates are attached together, just
In preservation and carry, it is not easy to lose；Can be a large amount of spare, in case replaced in time when damage, and uniform specification, it can be superimposed with multi-disc
It uses, to enhance magnetic force, reinforces sealing and the fixed performance of itself.
