[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0025] As introduced in the background, there are deficiencies in the prior art. In order to solve the above technical problems, the present application provides a steam flow adjusting structure based on unit shutdown.

[0026] Please refer to Figure 1 - Figure 5 A steam flow adjusting structure based on unit shutdown, comprising a main assembly 1, the main assembly 1 comprises a valve body 11, the valve body 11 is provided with a partition plate 12, the partition plate 12 is provided with a communication groove 13; the valve body 11 is further provided with an adjusting assembly 2, the adjusting assembly 2 comprises an inner cavity 21 opened at the upper end of the valve body 11, the inner cavity 21 is threadedly connected with a threaded rod 22 on the upper wall, the threaded rod 22 is screwed into the inner cavity 21 and fixed with a connecting piece 23 at one end, the connecting piece 23 is fixed with an adjusting piece 24 at the end away from the threaded rod 22, the inner cavity 21 is rotationally connected with a bevel gear one 25 at the bottom end, the bevel gear one 25 is further arranged on the outer circumferential side of the connecting piece 23, the inner cavity 21 is further rotationally connected with a handle two 261 on the side wall, the handle two 261 is rotationally connected with a bevel gear two 26 at the end extending into the inner cavity 21, the bevel gear one 25 and the bevel gear two 26 are engaged.

[0027] When using the device, it is installed on the equipment that needs to adjust the steam flow. By adjusting the assembly 2, the steam flow of the unit is closed and discharged. When using, first rotate the handle 221 to drive the threaded rod 22 to rotate, then the threaded rod 22 drives the connecting piece 23 to rotate, and finally the adjusting piece 24 is driven to separate from the communication groove 13, so that the two ends of the valve body 11 are communicated, and finally the steam flow of the unit is adjusted. At the same time, the adjusting assembly 2 of the device can also more carefully adjust the steam flow discharged by the unit. When a small amount of steam is needed, rotate the handle 261 to drive the bevel gear 26 to rotate. The bevel gear 26 is meshed with the bevel gear 25, which drives the bevel gear 25 to rotate, thereby driving the connecting piece 23 to rotate, and finally driving the adjusting piece 24 to separate from the communication groove 13. In this process, the inner diameter of the bevel gear 25 is much larger than that of the bevel gear 26, so that the bevel gear 26 rotates only a small amplitude, thereby reducing the adjustment amplitude, and finally achieving fine adjustment of the steam flow.

[0028] Further, the threaded rod 22 protruding from one end of the inner cavity 21 is fixed with the handle 221, which facilitates direct rotation of the threaded rod 22, thereby adjusting the adjusting piece 24, and finally controlling the opening and closing of the two ends of the valve body 11.

[0029] Further, the inner diameter of the bevel gear 25 is larger than that of the bevel gear 26, and the small gear drives the large gear to rotate, thereby reducing the rotation amplitude, and finally achieving fine adjustment.

[0030] Further, the bevel gear 25 and the connecting piece 23 are provided with a plurality of universal balls 251 on one surface, which are mainly used to offset the friction generated during the rotation and movement of the bevel gear 25 and the connecting piece 23.

[0031] Further, the connecting piece 23 is further provided with an extension tube 27 on the outer peripheral side. The extension tube 27 is fixed at the bottom end of the connecting piece 23, and the other end is rotatably connected to the inner wall of the valve body 11. The extension tube 27 is a rubber soft tube, which mainly plays a role in isolating the fluid.

[0032] Further, the valve body 11 is further provided with a flange plate 14, which is used for connecting the device with the pipeline of the unit.

[0033] Working principle: When using this device, simply install it on the equipment where steam flow needs to be regulated. The steam flow of the unit can be shut off or discharged via the regulating component 2. In use, first turn handle 221 to rotate the threaded rod 22, which then rotates the connecting piece 23, ultimately disengaging the regulating component 24 from the connecting groove 13, connecting the two ends of the valve body 11, thus regulating the steam flow of the unit. Simultaneously, the regulating component 2 can also more precisely regulate the steam flow discharged from the unit. When only a small amount of steam is needed, turn handle 261 to rotate the bevel gear 26. Since the bevel gear 26 meshes with the bevel gear 25, it will drive... The rotation of bevel gear 25 drives the connecting piece 23 to rotate, ultimately causing the adjusting piece 24 to disengage from the connecting groove 13. During this process, because the inner diameter of bevel gear 25 is much larger than that of bevel gear 26, bevel gear 25 only rotates slightly when bevel gear 26 rotates, thus significantly reducing the adjustment range and ultimately achieving fine adjustment of the steam flow. Several universal balls 251 are provided on the contact surface between bevel gear 25 and connecting piece 23. The universal balls 251 can counteract the friction generated during the rotation of connecting piece 23 by bevel gear 25, reduce the rotational force during adjustment, reduce the friction between bevel gear 25 and connecting piece 23, and increase the service life of the device.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
