Description

Technical Field

[0001] The utility model relates to the technical field of combined valve structures, in particular to a model-level reheat reserve regulating combined valve. Background Art

[0002] In the field of valve control technology, with the continuous development of industrial automation and precision control technology, the requirements for precise control and synchronous operation of valves are also increasing. Especially in model-level applications, such as reheat reserve systems, which are complex and require extremely high control accuracy, the accurate and fast response of valves becomes particularly critical. These systems require valves to accurately execute opening or closing instructions in a very short time to ensure the smooth progress of the process and the stable operation of the system.

[0003] In existing valve technology, when multiple valves need to be controlled simultaneously, this is usually achieved by adjusting the regulating rod of each valve individually. This method is not only cumbersome to operate, but also difficult to ensure the synchronization between multiple valves, and is prone to time differences or inconsistent adjustments during operation. Especially in situations where multiple valves need to be adjusted quickly and accurately, the limitations of this traditional method are more obvious. In view of this, we propose a model-level reheat reserve regulation combined valve. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A model-level reheat reserve regulating combined valve comprises a first valve 1 and a second valve 2 arranged in series, a first gear 4 is coaxially welded on the top of the valve regulating rod 6 of the first valve 1 and the second valve 2, a support 3 is detachably fixedly connected between the first valve 1 and the second valve 2, a threaded shaft 36 that can move up and down is included in the support 3, a second gear 5 is rotatably installed on the top of the threaded shaft 36, and when the second gear 5 moves to the height flush with the first gear 4, it meshes with both first gears 4, and the second gear 5 moves to the lowest point and disengages from both first gears 4. By welding the first gear 4 coaxially on the valve regulating rod 6, the valve regulating rod 6 is tightly combined with the gear, ensuring the accuracy and reliability of the transmission. The meshing design of the second gear 5 and the two first gears 4 allows the opening or closing state of the two valves to be synchronously controlled through one action, which significantly improves the operating efficiency and synchronization. The design of the support 3 and the threaded shaft 36 provides stable support for the vertical movement of the second gear 5, and can achieve the meshing or disengagement of the second gear 5 with the first gear 4.

[0025] As a preferred embodiment of the present invention, the first valve 1 and the second valve 2 are fixedly connected by a flange 7 and a plurality of fixing bolts 8, and the support member 3 is fixedly connected to the flange 7 by fixing bolts 8. Using the flange 7 and the fixing bolts 8 as a connection method not only ensures a stable connection between the first valve 1 and the second valve 2, but also facilitates the disassembly and maintenance of the entire system.

[0026] As a preferred embodiment of the present invention, the support member 3 includes a fixing block 30, a clamping opening 31 for accommodating two flanges 7 is provided at the bottom of the fixing block 30, and a through hole 32 is provided on the fixing block 30 for the fixing bolt 8 to pass through. The clamping opening 31 at the bottom of the fixing block 30 is designed to tightly accommodate the two flanges 7, thereby increasing the rigidity of the entire structure and reducing possible looseness or deformation during use. The design of the through hole 32 allows the fixing bolt 8 to easily pass through the fixing block 30, firmly connecting the support member 3 to the flange 7, and further enhancing the stability of the overall structure.

[0027] As a preferred embodiment of the present invention, a support shaft 34 is integrally formed at the top of the support member 3, and an adjusting knob 35 is rotatably connected to the top of the support shaft 34 and is threadedly connected to the outer wall of the threaded shaft 36. By rotating the adjusting knob 35, the lifting height of the threaded shaft 36 can be accurately controlled, thereby achieving fine adjustment of the position of the second gear 5, meeting the precise adjustment requirements in different application scenarios.

[0028] As a preferred embodiment of the present invention, the bottom of the threaded shaft 36 extends into the interior of the support shaft 34, and the threaded shaft 36 is slidably connected to the inner wall of the support shaft 34 through a limit slot 37 provided on the outer wall of the threaded shaft 36. The design of the limit slot 37 ensures the stability and accuracy of the threaded shaft 36 when it moves inside the support shaft 34, and effectively prevents the threaded shaft 36 from deflecting or shaking during the movement.

[0029] As a preferred embodiment of the present invention, an arc-shaped groove 33 that fits closely with the top of the valve is provided at the bottom of the fixing block 30. This fitting design also reduces the noise and vibration generated by the valve during operation, and improves the working efficiency and stability of the entire system.

[0030] As a preferred embodiment of the present invention, a handle 9 is rotatably mounted at the eccentric position of the top of the first gear 4 and the second gear 5. The design of the handle 9 provides a convenient force application point for the operator, making manual gear adjustment easier and more comfortable. In an emergency, the handle 9 can also be used as a handle for quick operation, thereby improving the emergency response capability of the system.

[0031] As a preferred embodiment of the present invention, the adjusting knob 35 is a nut of standard size. Using a nut of standard size as the adjusting knob 35 facilitates the operator to make quick adjustments using special tools.

[0032] When the model-level reheat reserve regulating combined valve of the utility model is used, when it is necessary to adjust the opening of the first valve 1 and the second valve 2, the operator first controls the lifting and lowering of the threaded shaft 36 by rotating the regulating knob 35. Since the regulating knob 35 is threadedly connected to the outer wall of the threaded shaft 36, rotating the regulating knob 35 causes the threaded shaft 36 to move up and down inside the support shaft 34.

[0033] When the threaded shaft 36 rises to a certain height, the second gear 5 on its top will mesh with the two first gears 4. At this time, the operator can synchronously adjust the opening of the first valve 1 and the second valve 2 by rotating the handle 9 on any gear. Since the second gear 5 is meshed with the two first gears 4 at the same time, rotating any gear will cause the other two gears to rotate at the same time, thereby achieving synchronous adjustment of the two valves.

[0034] When a certain valve needs to be adjusted separately, the operator can do so by rotating the handle 9 of the first gear 4 on the corresponding valve. At this time, the state of another valve will not be affected.

[0035] When in use, the operator can reversely rotate the adjusting knob 35 to lower the threaded shaft 36 and the second gear 5 to the lowest position, so that the second gear 5 is disengaged from the two first gears 4. At this time, the two valves can work independently without affecting each other.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
