The position control strip 902 is fixedly connected to the side of the position control pressure rod 901 away from the connecting tube 5. The position control strip 902 is used in conjunction with the position control column 803. The bottom of the position control pressure rod 901 is fixedly connected with a second spring 903.

[0030] The above solution is adopted: by setting the position control component 9, the positioning cross bar 801 can be driven to move, thereby releasing the fixation of the position of the positioning clamping rod 7, thereby releasing the installation fixation of the control valve 4.

[0032] By adopting the above solution, by providing the limiting vertical rod 11, the movement of the position control rod 901 in the inner cavity of the through hole 10 can be guided to prevent the position control rod 901 from being offset when moving.

[0033] refer to Figure 4The bottom of the positioning rod 7 extends to the inner cavity of the shell 6. The inner cavity of the shell 6 is provided with a blocking rod 12 used in conjunction with the positioning rod 7. The two sides of the blocking rod 12 are respectively fixedly connected to the two sides of the shell 6, and the top of the connecting pipe 5 is in contact with the bottom of the control valve 4.

[0034] By adopting the above solution, by providing the blocking rod 12 , the position of the positioning clamping rod 7 entering the inner cavity of the shell 6 can be additionally limited.

[0035] refer to Figure 4 The side of the positioning cross bar 801 close to the positioning card rod 7 is in contact with the positioning card rod 7, the rear side of the first spring 804 is fixedly connected to the rear side of the inner wall of the shell 6, the side of the limiting cross bar 806 close to the inner wall of the limiting groove 805 is in contact with the inner wall of the limiting groove 805, and the two sides of the limiting cross bar 806 are fixedly connected to the two sides of the inner wall of the shell 6.

[0039] The working principle of this utility model:

[0040] When in use, the user inserts the positioning card rod 7 into the inner cavity of the shell 6. During the process, the positioning card rod 7 squeezes the positioning cross bar 801, driving the positioning cross bar 801 to move backward. The positioning cross bar 801 drives the linkage rod 802 to move backward. The linkage rod 802 squeezes the first spring 804. When the bottom of the positioning card rod 7 contacts the blocking rod 12, the positioning cross bar 801 is reset under the thrust of the first spring 804. The position of the positioning card rod 7 is fixed by the positioning cross bar 801, thereby completing the installation and fixation of the control valve 4. The user presses the control pressure rod 901 downward, and the control pressure rod 901 While squeezing the second spring 903, the control bar 902 is driven to move downward, the control bar 902 drives the control column 803 to move backward, the control column 803 drives the connecting rod 802 to move backward, and the connecting rod 802 drives the positioning cross bar 801 to move backward, so that the positioning cross bar 801 releases the fixation of the positioning card rod 7. At this time, the user can pull the positioning card rod 7 out of the shell 6 to release the installation and fixation of the control valve 4, and at the same time loosen the control pressure rod 901, and under the thrust of the second spring 903, the control pressure rod 901 and the positioning cross bar 801 are driven to reset, so as to facilitate the next installation and fixation of the control valve 4.

[0041] To sum up: the steam generator with convenient replacement of the pressure control valve, by setting the connecting pipe 5, the shell 6, the positioning rod 7, the positioning assembly 8, the control assembly 9 and the port 10 for coordinated use, the positioning rod 7 is inserted into the inner cavity of the shell 6, during the process, the positioning rod 7 squeezes the positioning cross bar 801, drives the positioning cross bar 801 to move backward, and the positioning cross bar 801 drives the connecting rod 802 to move backward, which solves the problem that the existing pressure control valve is usually connected to the main engine of the steam generator by using threads, and this connection method is cumbersome to operate and inconvenient for users to disassemble and replace the pressure control valve.
