Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-4 As shown, the industrial steam desuperheating and pressure reducing device includes: a steam flow pipe 1 and a guide pipe 11. The guide pipe 11 is arranged opposite to the sealing plate 14, that is, the steam can be discharged through the guide pipe 11 when the sealing plate 14 is opened.

[0020] A pressure reducing mechanism that connects the steam flow pipe 1 and the guide pipe 11 together; the pressure reducing mechanism includes a mounting sleeve 2 installed on the guide pipe 11. The outer side of the mounting sleeve 2 is rectangular and the inner side is circular. The guide pipe 11 is installed on the mounting sleeve 2, and the mounting sleeve 2 is fitted over the outside of the guide pipe 11 and welded to seal the connection.

[0021] The air cylinder 7 is installed on the mounting sleeve 2, the mounting frame 12 is fixed in the mounting sleeve 2, the air cylinder 7 is installed on the mounting frame 12, the air cylinder 7 realizes suction of air through an external air pump, a control pipeline and the like, thereby controlling the air cylinder 7 to work, the output end of the air cylinder 7 is fixedly connected with the piston plate 13 sliding in the mounting sleeve 2, the adjusting spring 16 is fixed on the piston plate 13, the sealing plate 14 in sealing abutment with the steam flow pipe 1 is arranged on the steam flow pipe 1, wherein the sealing plate 14 seals and slides in the mounting sleeve 2; the pressure sensor 15 fixedly connected with the adjusting spring 16 is fixed on the sealing plate 14, and the pressure sensor 15 is a piezoelectric sensor.

[0022] The staff starts the air cylinder 7 to control the piston plate 13 to move, the piston plate 13 moving will extrude the adjusting spring 16, so that the adjusting spring 16 can generate pressure on the pressure sensor 15, thereby generating pressure on the sealing plate 14, so that the sealing plate 14 seals the steam flow pipe 1.

[0023] When it is necessary to reduce the pressure of the steam flow pipe 1, the output end of the air cylinder 7 is retracted, so as to reduce the pressure on the pressure sensor 15, thereby reducing the pressure of the sealing plate 14 on the steam flow pipe 1, when the pressure in the steam flow pipe 1 is greater than the pressure of the adjusting spring 16 on the sealing plate 14, the sealing plate 14 will be pushed open, realizing automatic pressure relief.

[0024] By adjusting the air cylinder 7 to drive the piston plate 13 to extrude the adjusting spring 16, the pressure on the sealing plate 14 can be controlled, thereby the pressure during pressure relief can be controlled, and the specific calculation is as follows:

[0025] Determine the value of the force area S, that is, the area of the sealing plate 14;

[0026] Use the deformation F=P×S of the pressure formula P=F / S to calculate the pressure value. Substitute the known pressure value and the force area into the formula, and the pressure F value can be obtained, wherein P is the pressure in the steam flow pipe 1;

[0027] Unit conversion: convert the pressure value to other units, for example, newton (N), then the calculated pressure value can be directly used, which corresponds to the pressure F in the pressure formula.

[0028] For example, if the pressure of air is 1 bar and the force area is 1 m², the pressure value can be calculated by the following steps:

[0029] F = P × S = 1 bar × 1 m² = 1 bar × 100000 Pa / bar = 100000 Pa

[0030] Since 1 Pa = 1 N / m², the pressure F can also be expressed as:

[0031] F = 100000 Pa = 100000 N / m² = 100000 N (in the case of force area is 1 m²)

[0032] As described above, it can be known that the pressure value of the steam flow pipe 1 to the sealing plate 14, by controlling the cylinder 7 to extrude the compression amount of the adjusting spring 16, the pressure value to the sealing plate 14 can be known through the pressure sensor 15, so that the steam flow pipe 1 can be accurately and automatically decompressed.
