specific Embodiment approach 1
[0009] Specific implementation mode one: combine Figure 1 to Figure 7 Describe this embodiment, the steam turbine steam pipeline superheated steam moisture detection sensor of this embodiment includes a circular tubular shell 1, a short pipe 2, an insulating cylinder 3, a first optical fiber 4-1, a second optical fiber 4-2, and a third optical fiber 4 -3, wire ring 5, cylindrical metal box 6, front insulating plate 7, light-emitting diode 8, photocell 9, first metal cover 10, second metal cover 11, box cover 12, rear insulating plate 17, measuring resistance R 0 , compensation resistor R 1 , adjustable resistance R 2 , the first pair of terminals 16 and the second pair of terminals 18;
[0010] The short tube 2 is a short tube with one end closed, the open section of the short tube 2 is inserted into the front end of the round tubular shell 1, the closed end of the short tube 2 is fixedly connected with the round tubular shell 1, and the inner end surface of the closed end ...
specific Embodiment approach 2
[0014] Specific implementation mode two: combination figure 1 This embodiment will be described. The short pipe 2 of this embodiment is made of stainless steel. So set, the service life is longer. Other components and connections are the same as those in the first embodiment.
specific Embodiment approach 3
[0015] Specific implementation mode three: combination figure 1 and figure 2 To illustrate this embodiment, each exhaust hole 2-1 of this embodiment includes 5 small holes, the diameter of which is 4 mm, and the center distance between the holes is 8 mm. With such setting, the separation effect of soda and water is better. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.
