[0018] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1 - 5 , the present utility model provides a technical solution.
[0020] An emergency braking mechanism for a numerical control flow valve includes a flow valve body 1 and a pipe connector 2; the pipe connector 2 is installed on both sides of the flow valve body 1, and a braking head frame 19, a fixed plate 3, a bolt hole 4, a fixed bolt 5 and an emergency braking component are provided on the pipe connector 2;
[0021] The fixed plate 3 is installed on the braking head frame 19, the bolt hole 4 is opened on the fixed plate 3, and the braking head frame 19 is fixed by using the fixed bolt 5 through the fixed plate 3;
[0022] The emergency braking assembly includes: a water retaining plate 6, a water passing hole 7, an annular slideway 8, an annular slider 9, a rotating disk 10, a toothed ring 11, a driving groove 12, a transverse rotating shaft 13, a transmission gear 14, a main bevel gear 15, a sub-bevel gear 16, a longitudinal rotating shaft 17, and a handle 18;
[0023] The water retaining plate 6 is fixedly installed in the braking head frame 19. The annular slideway 8 is opened on the surface of the water retaining plate 6. The rotating disk 10 is installed on the annular slideway 8 through the annular slider 9. The water passing hole 7 is opened on the rotating disk 10 and the water retaining plate 6. The toothed ring 11 is sleeved on the rotating disk 10. The driving groove 12 is opened on the pipe connector 2. The transverse rotating shaft 13 is installed in the driving groove 12. The transmission gear 14 is sleeved on the transverse rotating shaft 13 and meshes with the toothed ring 11. The sub-bevel gear 16 is sleeved on the front end of the transverse rotating shaft 13. The longitudinal rotating shaft 17 is installed in the driving groove 12 and extends out of the driving groove 12. The main bevel gear 15 is sleeved on the longitudinal rotating shaft 17 and meshes with the sub-bevel gear 16. The handle 18 is connected to the top of the longitudinal rotating shaft 17;
[0024] It should be noted that when the flow valve body 1 fails and needs to be disassembled and repaired, by rotating the handle 18, the longitudinal rotating shaft 17 drives the main bevel gear 15 to rotate. The main bevel gear 15 drives the sub-bevel gear 16 to rotate. The sub-bevel gear 16 drives the transmission gear 14 to rotate through the transverse rotating shaft 13, thereby driving the rotating disk 10 to rotate on the annular slideway 8 through the annular slider 9. Thus, the water passing hole 7 of the water retaining plate 6 is blocked by the unperforated part on the rotating disk 10, so that the water flow can be sealed, isolating the impact force of the water flow for the flow valve body 1. Subsequently, the fixing bolt 5 can be disassembled, and then the pipe connector 2 on the flow valve body 1 can be disassembled and separated from the braking head frame 19, and then it is convenient to repair the flow valve body 1.
[0025] Preferably, furthermore, a connecting flange is provided on the braking head frame 19.
[0026] It should be noted that the connecting flange is used to facilitate the connection with the water pipe line.
[0027] Preferably, furthermore, a sealing ring is provided at the docking part of the braking head frame 19 and the pipe connector 2.
[0028] It should be noted that the sealing ring is used to ensure the sealing performance of the connection between the braking head frame 19 and the pipe connector 2.
[0029] Preferably, furthermore, a limiting slideway is provided at the top of the braking head frame 19, and a limiting frame is provided on the handle 18.
[0030] It should be noted that the rotation angle of the handle 18 can be limited by the limiting slideway and the limiting frame, so that the rotating disc 10 can rotate by a fixed angle.
[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
