Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to a full-process reheat steam temperature controller with an automatic adjustment function. Background Art

[0002] After the superheated steam enters the steam turbine and does work, the pressure and temperature of the steam drop. In order to recycle, this part of the steam is led back to the boiler's reheater for heating to improve the quality of the steam so that it can do work again. In short, the steam that passes through the reheater is called reheated steam. Reheated steam temperature control refers to controlling and maintaining the reheater outlet steam temperature at a given value. When the reheated steam temperature is low, it will reduce the unit's thermal cycle efficiency and affect the safe operation of the unit; if the reheater temperature is too high, the safety factor of the metal pipe strength will decrease, reducing the unit's thermal cycle efficiency.

[0003] However, the existing reheat steam temperature controller is installed inside the equipment by screws, and professional tools are required for installation and removal, which makes operation inconvenient. In view of the above problems, the inventor proposes a reheat steam temperature full-process controller with automatic adjustment function to solve the above problems. Utility Model Content

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. Through the cooperation between the clamping block, the clamping plate, the spring, the clamping slot and the unlocking rod, when the temperature controller moves to contact with the clamping block, the clamping block and the clamping plate are pushed to move to one side of the spring and squeeze the spring.

[0021] The ejection assembly includes a fixed block 11, which is fixedly connected to the bottom end of the mounting base 1. A slide groove 12 is provided inside the fixed block 11. A slide plate 13 is slidably engaged inside the slide groove 12. A compression spring 14 is provided between one side of the slide plate 13 and one side of the inner wall of the slide groove 12. A limiting groove 15 is provided at the bottom end of the temperature controller 3, and the slide plate 13 is slidably engaged in the limiting groove 15.

[0022] By adopting the above technical solution, when the temperature controller 3 slides into the installation groove 2, the cooperation between the limit groove 15 and the slide plate 13 is utilized to push the slide plate 13 to slide toward the side of the compression spring 14, and compress the compression spring 14, so that the compression spring 14 is in a compressed state. When the temperature controller 3 needs to be disassembled, the elastic force of the compression spring 14 is utilized to push the slide plate 13 to move to the side away from the compression spring 14, thereby pushing the temperature controller 3 out from the inside of the installation groove 2, making it convenient to disassemble the temperature controller 3.

[0023] Both sides of the inner wall of the installation groove 2 are fixedly connected with guide slide blocks 16 , and both sides of the temperature controller 3 are provided with guide rails 17 , and the guide rails 17 are slidably engaged in the guide slide blocks 16 .

[0024] By adopting the above technical solution, the cooperation between the guide slider 16 and the guide rail 17 facilitates the lateral movement of the temperature controller 3 to be guided, thereby facilitating the installation of the temperature controller 3 .

[0025] A release lever 8 is disposed on one side of the temperature controller 3 , and one end of the release lever 8 extends into the plate groove 4 and is slidably connected to the inclined surface of the clamping plate 5 .

[0026] By adopting the above technical solution and providing the unlocking rod 8, when the unlocking rod 8 is pressed, the inclined surface of the clamping plate 5 is used to guide the movement of the unlocking rod 8, thereby achieving the unlocking operation.

[0027] A spring 10 is provided between a side of the clamping plate 5 away from the clamping block 6 and a side of the inner wall of the plate groove 4 .

[0028] By adopting the above technical solution and providing the spring 10, it is convenient to reset the clamping plate 5 and the clamping block 6.

[0029] One end of the unlocking rod 8 close to the clamping plate 5 is fixedly connected to the limiting block 9 .

[0031] The sides of the clamping blocks 6 that are close to each other are all configured as inclined surfaces.

[0032] By adopting the above technical solution, by setting the sides of the clamping blocks 6 that are close to each other as inclined surfaces, when the temperature controller 3 contacts the clamping block 6, it is convenient to better push the clamping block 6 for clamping.

[0033] Working principle: when installing the temperature controller 3, make the temperature controller 3 correspond to the position of the installation slot 2, and make the guide slider 16 and the guide rail 17 correspond to each other, then push the temperature controller 3 into the interior of the installation slot 2, and use the cooperation between the guide rail 17 and the guide slider 16 to guide the lateral movement of the temperature controller 3. When the temperature controller 3 slides to one side of the limit slot 15 and contacts the slide plate 13, the slide plate 13 is pushed to slide to one side of the compression spring 14, and the compression spring 14 is compressed, so that the compression spring 14 is in a compressed state. When the temperature controller 3 moves to contact the clamping block 6, the clamping block 6 and the clamping plate 5 are pushed to move to one side of the spring 10 and squeeze the spring 10. When the temperature controller 3 moves to the position where the clamping block 6 corresponds to the clamping slot 7, the elastic force of the spring 10 is used to insert the clamping block 6 into the interior of the clamping slot 7, thereby installing and fixing the position of the temperature controller 3.

[0034] When the temperature controller 3 needs to be disassembled, the unlocking rod 8 is pressed and the inclined surface of the clamping plate 5 is used to guide the movement of the unlocking rod 8, so that the clamping block 6 is disengaged from the inside of the clamping slot 7, thereby releasing the restriction on the temperature controller 3. At the same time, the elastic force of the compression spring 14 is used to push the slide plate 13 to the side away from the compression spring 14, thereby pushing a part of the temperature controller 3 out of the inside of the installation slot 2, thereby facilitating the temperature controller 3 to be pulled out from the inside of the installation slot 2.
