The output end of the boiler 1 is connected to a regulator 2 in a communicating way. The top end of the regulator 2 is connected to an air pipe 3 in a communicating way. Above the outer wall of the air pipe 3, a control structure 4 is provided;

[0035] The control structure 4 includes a controller 401 which is fixedly connected to the air pipe 3. The top end of the controller 401 is fixedly connected to a first motor 402.

During the operation of the boiler 1, the first motor 402 outside the controller 401 cooperates with the second motor 406 to control the internal sealing structure. When the downward pressing sealing block 404 closes into the air pipe 3 and closes the passage, the driving gear 407 rotates, driving the vertical rod 408 to descend to open the sealing column, exposing the air hole. The internal steam passage is that the steam passes through the through groove inside the controller 401 and is quickly discharged through the air outlet pipe 409, thereby relieving the pressure inside the high-pressure / intermediate-pressure cylinder 7. When the downward pressing sealing block 404 and the sealing column at the bottom end of the vertical rod 408 are all retracted into the controller 401 to keep the air pipe 3 of the high-pressure / intermediate-pressure cylinder 7 unblocked.

[0037] Specifically, as Figure 1 , Figure 3 , Figure 4 and Figure 5 there is a pressure detection structure 6 at the front end of the high-pressure / intermediate-pressure cylinder 7 in

[0038] The pressure detection structure 6 includes a connecting pipe 601. A mounting disc 602 is attached to the opening of the connecting pipe 601. Bolts 603 are provided inside the mounting disc 602. The bolts 603 penetrate through the mounting disc 602 and are screwed to the flange of the connecting pipe 601.

The other end of the mounting disc 602 is fixedly connected to a damping rod 606. The other end of the damping rod 606 is fixedly connected to a positioning ring 607. The other end of the positioning ring 607 is fixedly connected to a barometric pressure detector 608. The barometric pressure detector 608 is located inside the cavity of the connecting pipe 601. A summary detection structure 8 is provided at the middle position of the pressure detection structure 6.

[0039] The aggregated detection structure 8 includes a butt joint pipe 801, which fits with the connecting pipe 601. The other end of the butt joint pipe 801 is fixedly connected with a management control cabinet 802. Above the front end of the management control cabinet 802, a display 803 is fixedly connected. At the lower right of the front end of the management control cabinet 802, an alarm lamp 804 is fixedly connected. A positioning column 806 is embedded in the interior of the connecting pipe 601. One end of the positioning column 806 is fixedly connected with a signal connecting pipe 805, and the signal connecting pipe 805 is docked with the management control cabinet 802. The other end of the positioning column 806 is fixedly connected with a detection part 810. A groove is formed at the front end of the positioning column 806. An elastic platform 807 is fixedly connected inside the groove of the positioning column 806. A gasket 808 is fixedly connected to the front end of the elastic platform 807. A signal receiver 809 is fixedly connected to the front end of the gasket 808, and the signal receiver 809 is engaged with the connecting pipe 601. The detection gauges 605 that can be quickly installed are symmetrically arranged on the two cylinder connecting pipes 601 of the high-pressure - medium-pressure cylinder 7 respectively to detect the high pressure and the low pressure respectively. And according to the detected pressure range, different models of detection gauges 605 can be used to achieve the best use effect, detect more accurate pressure data, and thus perform subsequent operations. At the same time, the detection part 810 that can perform secondary detection works with the control device of the management control cabinet 802 to adjust and process the pressure.

[0040] Working process: The electrical appliance of this device is an external power supply. The staff assembles it. The controller 401 of the control structure 4 is welded to the outer wall above the air pipe 3. The air pressure detector 608 in the pressure detection structure 6 is inserted into the through hole of the connecting pipe 601. Keep pushing the mounting disc 602 into the connecting pipe 601. The damping rod 606 contracts under force, and the positioning ring 607 moves to the outside of the through hole to fit. The surface of the mounting disc 602 is fitted to the surface of the connecting pipe 601. Bolts 603 are inserted into the mounting holes of the mounting disc 602 and tightened to fix the fixing rod 604 and the detection gauge 605. Repeat the above operation to install another detection gauge 605 on the medium-pressure cylinder connecting pipe 601 in the high-pressure - medium-pressure cylinder 7 to complete the assembly.

[0041] Take out the signal receiver 809 in the aggregated detection structure 8. Push the detection part 810 of the signal receiver 809 into the opening of the bent connecting pipe 601. Keep pushing the signal receiver 809 into the empty slot of the connecting pipe 601. The elastic platform 807 in the groove of the positioning column 806 pushes the gasket 808 and the signal receiver 809 to be pressed tightly into the empty slot, and the gasket 808 seals to complete the positioning of the signal receiver 809. Then align the butt joint pipe 801 of the management control cabinet 802 with the opening of the connecting pipe 601 and tighten and install it with screws. The signal connecting pipe 805 is inserted into the interior of the management control cabinet 802 and connected to the signal receiver 809 to complete the installation.

[0042] During operation, the steam generated by the boiler 1 enters the inside of the high-pressure - medium-pressure cylinder 7 below the through pipe 5 through the regulator 2 and the air pipe 3. The rotary prime mover inside converts the thermal energy with steam as the working medium into mechanical energy, driving the generator to generate electricity or mechanical rotation. The air pressure inside the high-pressure - medium-pressure cylinder 7 is detected by the air pressure detector 608 inside the connecting pipe 601 and the detection unit 810. The detected air pressure is displayed by the detection meter 605 on the fixed rod 604 for the monitoring of the staff. The summarized data is transmitted into the management control cabinet 802 through the signal receiver 809 for data entry, and combined with the secondary detection of the detection unit 809 to determine the accuracy of the detection data, thereby judging whether the pressure of the high-pressure - medium-pressure cylinder is normal;

[0043] Normal pressure: The device operates continuously, generating electricity or mechanical rotation continuously;

[0044] Abnormal pressure: The management control cabinet 802 sends a signal, and the alarm lamp 804 alarms quickly to remind the staff that the pressure of the high-pressure - medium-pressure cylinder 7 is abnormal. At the same time, it controls the controller 401 to work, driving the first motor 402 above the high-pressure - medium-pressure cylinder 7 on the side with higher pressure to start working, driving the threaded shaft 403 to rotate, and controlling the outer pressing sealing block 404 to move towards the upper opening of the through pipe 5 below through the guidance of the pulley 405. The pressing sealing block 404 completes the sealing of the upper opening of the through pipe 5, preventing the continuous entry of steam. At the same time, the second motor 406 on another controller 401 starts to work, driving the gear 407 to rotate, driving the vertical rod 408 to start descending, opening the sealing column, exposing the air holes, and quickly discharging the excess steam through the air outlet pipe 409 to slow down the pressure, so that the internal pressure of the high-pressure - medium-pressure cylinder 7 gradually eases. After reaching the normal state, it controls the first motor 402 and the second motor 406 to work again, controlling the sealing structure to reset, which is simple to use.

A transmission shaft 908 is provided between the two discs 901, and the transmission shaft 908 is fixedly connected to the turntable 903 inside the disc 901. By using a separate third motor 902 to rotate clockwise, the movement operation of the sealing head 907 can be completed, so as to seal or open the upper opening of the through pipe 5. The use is simple, and the operation of adjusting the air pressure inside the high-pressure - medium-pressure cylinder 7 is very effective, reducing costs and extra losses at the same time.

[0049] Working process: In Embodiment 2, the same parts as in Embodiment 1 will not be described in detail.
