[0002] Valves are control components in pipeline fluid delivery systems. They are used to change the cross-section of the passage and the direction of medium flow. They have functions such as diversion, cutoff, throttling, check, diversion or overflow pressure relief. Valves used for fluid control come in a wide variety of varieties and specifications, from the simplest stop valves to various valves used in extremely complex automatic control systems. Valves can usually be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids.

[0018] 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.

[0019] See also Figure 1-2 A stop valve with a manual emergency switch in this embodiment includes a pipeline body 1, and an adjusting switch mechanism is arranged inside and on the top of the pipeline body 1.

[0020] In this embodiment, the regulating switch mechanism includes an regulating frame 2 fixedly mounted on the top of the pipe body 1, a reciprocating screw 3 is rotatably connected inside the regulating frame 2, a rotating rod 4 is rotatably connected to one side of the regulating frame 2, a movable groove is provided on the left side of the regulating frame 2, the rotating rod 4 is rotatably connected to the regulating frame 2 through the movable groove, so as to facilitate the rotation of the rotating rod 4, a rocker 5 is fixedly mounted on the left side of the rotating rod 4, and an active bevel gear 6 is fixedly mounted on the right side of the rotating rod 4.

[0021] Among them, the right side of the active bevel gear 6 is meshed with a driven bevel gear 7 fixedly connected to the reciprocating screw 3, the outer side of the reciprocating screw 3 is threadedly connected to a thread block 8, a thread groove is provided inside the thread block 8, and the thread block 8 is threadedly connected to the reciprocating screw 3 through the thread groove, which facilitates the movement of the thread block 8 on the reciprocating screw 3, and limit rods 9 slidably connected to the adjustment frame 2 are fixedly installed on the left and right sides of the thread block 8.

[0022] In this embodiment, limit grooves are provided on the inner walls on the left and right sides of the adjusting frame 2, and the limit rod 9 is slidably connected to the adjusting frame 2 through the limit grooves, which is convenient for limiting the limit rod 9. A support rod 10 slidably connected to the adjusting frame 2 is fixedly installed at the bottom of the threaded block 8, and a slide groove is provided at the bottom of the adjusting frame 2. The support rod 10 is slidably connected to the adjusting frame 2 through the slide groove, which is convenient for the support rod 10 to be lifted and lowered.

[0024] It should be noted that the stop valve with a manual emergency switch can drive the reciprocating screw 3 to rotate under the action of the rocker 5, the active bevel gear 6 and the driven bevel gear 7 through the arranged adjusting switch mechanism, so as to facilitate the movement of the threaded block 8 to drive the mounting plate 12 and the sealing valve 13 to move downward, so that the sealing valve 13 blocks and closes the flow hole inside the pipeline body 1, so as to achieve rapid closure in an emergency.
