Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of ceramic wear-resisting Wind Speed of Boiler in Power Station measurement mechanism.
Background technology
Existing Wind Speed of Boiler in Power Station measurement mechanism indirectly reflects the wind speed in airduct by the method for measuring airduct total head, static pressure; But; in the measurement of a wind of station boiler; owing to containing a large amount of pulverized coal particles in a wind; swiftly flowing particle can wash away stopple coupon, wear and tear; cause the damage of pressure port and pressure pipe; thereby size that cannot Measurement accuracy wind speed, thus the safety on boiler and economic performance cause very large impact, therefore existing Wind Speed of Boiler in Power Station measurement mechanism structural design is not scientific and reasonable, measuring wind speed precision is little, stability and Practical Performance poor.
Utility model content
In order to solve the existing weak point of above-mentioned technology, the utility model discloses a kind of ceramic wear-resisting Wind Speed of Boiler in Power Station measurement mechanism.
In order to solve above technical matters, the technical solution adopted in the utility model is: a kind of ceramic wear-resisting Wind Speed of Boiler in Power Station measurement mechanism, comprise dynamic pressure tube, static tube, the top of dynamic pressure tube and static tube is provided with pressure pipe sealing plug, and the lower end of dynamic pressure tube and static tube is wedge shape;
On the side pipe of the upper end of dynamic pressure tube and static tube, be respectively equipped with pressure measurement pressure pipe; Pressure measurement pressure pipe is connected with sensor; The top of side pipe is provided with side pipe sealing plug; On dynamic pressure tube and static tube, the below of side pipe is provided with flange; The two ends of flange are provided with screw bolt and nut; The centre of flange is provided with sealing gasket; The outside of dynamic pressure tube and static tube is metal stainless-steel tube; The outside of the following metal stainless-steel tube of flange is ceramic pipe.
The utility model design science rationally, large, the stability of measuring wind speed precision and practicality better.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic cross-section that the flange of Fig. 1 connects.
Embodiment
As shown in Figure 1, the utility model comprises dynamic pressure tube 9 and static tube 10, and the top of dynamic pressure tube 9 and static tube 10 is provided with pressure pipe sealing plug 2, and the lower end of dynamic pressure tube 9 and static tube 10 is wedge shape; On the side pipe of the upper end of dynamic pressure tube 9 and static tube 10, be respectively equipped with pressure measurement pressure pipe 1, pressure measurement pressure pipe 1 is connected with sensor, and the top of side pipe is provided with side pipe sealing plug 11.On dynamic pressure tube 9 and static tube 10, the below of side pipe is provided with flange 4; The two ends of flange 4 are provided with bolt 3 and nut 5.The centre of flange 4 is provided with sealing gasket 8.The outside of dynamic pressure tube 9 and static tube 10 is metal stainless-steel tube 6, and the outside of the following metal stainless-steel tube 6 of flange 4 is ceramic pipe 7.
The utility model adopts flange 4 to connect, and flange welding, on built-in pipe, is fixed on dynamic pressure tube 9 and static tube 10 in airduct by flange, and wherein pitot aperture is just to airflow direction.When measurement, by flange 4, ceramic pipe is fixed in wind pipeline, pitot aperture, just to airflow direction, is connected to by pressure measurement pressure pipe 1 measured value that sensor records pressure and then obtains wind speed; Pressure measurement pressure pipe in pipeline is not frayed by the protection of wear resistance ceramic tube 7, thereby ensures that the precision of measurement and the safe operation that accuracy is station boiler provide more reliable data.
The utility model has adopted wear-resisting ceramic pipe and metal stainless-steel tube, wherein in metal stainless-steel tube, is lining in ceramic pipe inner by welding and hyperthermia drying technology, thereby has ensured the soldering reliability of two kinds of materials.
