[0024] A cast steel high-temperature ball valve with a protective structure: comprising a valve body 1, a flange 2 is fixedly connected to the surface of the valve body 1, a protective mechanism is arranged on the surface of the valve body 1, the protective mechanism comprises a solenoid 3, the solenoid 3 is fixedly connected to the surface of the valve body 1, a screw barrel 4 is threadedly connected to the surface of the solenoid 3, an adjustment mechanism is arranged on the surface of the valve body 1, the adjustment mechanism comprises a short handle 5, the short handle 5 is arranged on the surface of the valve body 1, a guide block 6 is fixedly connected to the surface of the short handle 5, an adjustment handle 7 is slidably connected to the surface of the guide block 6, and a fixed A limiting hole 8 is provided on the surface of the adjusting handle 7, a limiting hole 9 is provided on the surface of the guide block 6, a spring 10 is fixedly connected to the surface of the spring 10, and a limiting rod 11 is fixedly connected to the surface of the spring 10. The protective mechanism can completely protect the connection between the short handle 5 and the valve body 1 to prevent dust, paint and other debris from preventing the short handle 5 from continuing to rotate. At the same time, the adjusting handle 7 and the short handle 5 form a handle. The adjusting handle 7 on the short handle 5 can control the length of the handle, thereby reducing the diameter of the screw tube 3, and by adjusting the length of the handle, the worker can operate more comfortably.

[0025] Furthermore, the inner circle radius of the spiral tube 3 is greater than the length of the short handle 5, and the inner circle diameter of the spiral tube 3 is greater than the length of the adjustment handle 7, so that the spiral tube 3 and the spiral barrel 4 can cover the short handle 5 and the adjustment handle 7 on the surface of the valve body 1 to block them.

[0026] Furthermore, the screw barrel 4 is installed on the surface of the valve body 1 through the screw tube 3. The screw barrel 4 cooperates with the screw tube 3 to cover the upper surface of the valve body 1, and the connection between the handle and the valve body 1 is on the upper surface of the valve body 1. The screw tube 3 and the screw barrel 4 can fully cover the connection between the short handle 5 and the valve body 1, and can also cover the adjustment handle 7 on the short handle 5.

[0027] Furthermore, the guide block 6 is in a "U" shape, and a guide groove is formed on the surface of the short handle 5, and the adjusting handle 7 slides on the guide groove. The adjusting handle 7 changes its position on the short handle 5 by sliding, and also changes the length of the handle, thereby facilitating the use of the protective mechanism on the valve body 1.

[0028] Furthermore, the adjusting handle 7 is in a "U" shape, a plurality of positioning holes 8 are arranged on the surface of the adjusting handle 7 and are linearly and evenly arranged on one side of the adjusting handle 7, and the limiting holes 9 are arranged on the side of the adjusting handle 7 away from the positioning holes 8.

[0029] Furthermore, a guide hole is opened on the surface of the guide block 6, and the limit rod 11 slides on the guide hole of the guide block 6. The elastic force of the spring 10 acts on the limit rod 11. Under the action of the elastic force of the spring 10, the limit rod 11 will contact and connect to the surface of the adjusting handle 7. When the limit rod 11 passes through the positioning hole 8 or the limit hole 9, the limit rod 11 will contact and connect to the surface of the short handle 5.

[0030] Furthermore, the adjusting handle 7 changes the position of the positioning hole 8 and the limiting hole 9 by sliding on the guide block 6. The limiting rod 11 can be inserted into the limiting hole 9 or one group of positioning holes 8. The limiting rod 11 limits the position of the adjusting handle 7 on the short handle 5 through the positioning hole 8 and the limiting hole 9. By changing the position of the adjusting handle 7 on the short handle 5, the length of the handle can be changed.

[0031] Working principle: Pull the limit rod 11 on the surface of the guide block 6 to deform the spring 10. At this time, slide the adjusting handle 7 on the guide groove at the bottom of the guide block 6 to change the positions of the positioning hole 8 and the limit hole 9. Loosen the limit rod 11. Under the elastic force of the spring 10, when the limit rod 11 passes through one group of positioning holes 8, the length of the handle can be adjusted within a certain range by passing through different positioning holes 8. When the limit rod 11 passes through the limit hole 9, the adjusting handle 7 is in a storage state on the short handle 5. At this time, the protective mechanism can be enabled, and the screw barrel 4 is threadedly connected to the surface of the screw tube 3. The screw barrel 4 cooperates with the screw tube 3 to completely cover the connection between the short handle 5 and the valve body 1.
