Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to an automatic reset double-adjustment stop valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. Among them, the stop valve is also a type of valve.

[0003] According to an automatic reset double-adjustment stop valve disclosed in Chinese patent CN202221116233.4, this application can quickly release the locking state of the opposite column by setting a second threaded sleeve and a locking rod, which is convenient for the rapid separation of the fixing box and the bracket. At the same time, the design of the locking mechanism can quickly release the locking state of the card block, so that it can quickly detach from the card seat. Then the user pulls up the fixing box to quickly separate the small motor and the threaded rod, and quickly adjusts the stop valve body from the electric control state to the manual state, which is convenient for repairing the damaged small motor and will not affect the normal use of the stop valve body. When the existing automatic reset double-adjustment stop valve is adjusted to the manual state due to a motor failure, it is necessary to use an external tool to rotate the screw rod, which is more troublesome to use.

[0029] Embodiment 2;

[0030] like Figure 1-7As shown, it includes a stop valve body 1, the outer wall of the stop valve body 1 is provided with a mounting plate 2, the mounting plate 2 is connected to the stop valve body 1 through a connecting column 3, the top of the mounting plate 2 is provided with a protective shell 4, the top of the protective shell 4 is provided with a cover plate 5, the outer wall of the stop valve body 1 is provided with a screw rod 6 threadedly connected thereto, the top of the screw rod 6 passes through the mounting plate 2 and extends into the protective shell 4, the bottom end of the cover plate 5 is provided with a servo motor 7, the driving end of the servo motor 7 is provided with a connecting shaft 8, the bottom end of the connecting shaft 8 extends into the screw rod 6, the top of the screw rod 6 is provided with a travel groove 9 matching the connecting shaft 8, a symmetrically arranged limit key 10 is provided in the travel groove 9 and on the outer wall of the connecting shaft 8, a keyway 11 matching the limit key 10 is provided on the screw rod 6, and a manual adjustment component is provided in the protective shell 4 and on the outer wall of the screw rod 6. The protective shell 4 is connected to the mounting plate 2 via a hand-tightening bolt 12, and the cover plate 5 is connected to the protective shell 4 via a hand-tightening bolt 2 13. A shell door 14 is provided on one side of the protective shell 4, and a lifting ring 15 is provided on the top of the cover plate 5. Through holes matching the screw rod 6 are provided on both the mounting plate 2 and the protective shell 4, and a limiting plate 16 is provided at the bottom end of the mounting plate 2 and fixedly sleeved on the screw rod 6. The manual adjustment assembly includes a mounting ring 17 and a mounting ring 2 18 symmetrically arranged in the protective shell 4 and on the outer wall of the screw rod 6.
