[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-4 The utility model provides an embodiment: a high-temperature C-shaped rotary valve for a coking device, comprising a C-shaped rotary valve body 1, the upper end of the C-shaped rotary valve body 1 is rotatably connected to a valve stem 102, the lower end of the C-shaped rotary valve body 1 is rotatably connected to a rotating shaft 103, a liquid outlet 104 is arranged on one side of the C-shaped rotary valve body 1, a C-shaped valve core 3 is rotatably connected to the C-shaped rotary valve body 1, a hydraulically sealed valve body 2 is connected to one side of the C-shaped rotary valve body 1, a liquid inlet 204 is arranged inside the hydraulically sealed valve body 2, a hydraulically sealed part 201 is arranged on the hydraulically sealed valve body 2, a connecting ring 202 is fixedly connected to one side of the hydraulically sealed part 201, four hydraulic chambers 205 are arranged in an annular array inside the hydraulically sealed part 201, a sealing ring seat 4 is arranged on one side of the four hydraulic chambers 205, four fixing rods 401 are fixedly connected to one side of the sealing ring seat 4 in an annular array, and an annular sealing ring 402 is fixedly connected to one side of the sealing ring seat 4.

[0024] Furthermore, the lower end of the valve stem 102 extends through the C-shaped rotary valve body 1 to the interior and is fixedly connected to the middle part of the upper end of the C-shaped valve core 3. The middle part of the lower end of the C-shaped valve core 3 is fixedly connected to the rotating shaft 103. The C-shaped valve core 3 is driven to rotate by rotating the valve stem 102, so that the C-shaped valve core 3 is fitted with the sealing ring seat 4 to achieve the closure of the C-shaped rotary valve body 1. When the C-shaped valve core 3 rotates 90 degrees counterclockwise, the interior of the C-shaped rotary valve body 1 is connected with the hydraulically sealed valve body 2, that is, the C-shaped rotary valve body 1 is opened.

[0025] Furthermore, a plurality of threaded holes 101 are provided in a circular array on one end surface of the C-shaped rotary valve body 1 .

[0026] Furthermore, the C-shaped rotary valve body 1 and the hydraulically sealed valve body 2 are threadedly connected and fixed by means of bolts 203 passing through the connecting ring 202 and inserted into the threaded hole 101, so that the C-shaped rotary valve body 1 and the hydraulically sealed valve body 2 are easy to disassemble and the internal components are easy to repair and replace.

[0027] Furthermore, one side of the interior of each hydraulic chamber 205 is connected to the interior of the hydraulic airtight valve body 2 via the pressure relief hole 207 , so that the liquid in the hydraulic chamber 205 can enter the interior of the hydraulic airtight valve body 2 through the pressure relief hole 207 .

[0028] Furthermore, springs 206 are provided inside the four hydraulic chambers 205, and four fixing rods 401 on the sealing ring seat 4 are respectively inserted into the four hydraulic chambers 205 and fixedly connected to one end of the spring 206. When the C-shaped valve core 3 rotates and fits the sealing ring seat 4, the sealing ring seat 4 is squeezed to make the fixing rod 401 extend into the hydraulic chamber 205. The fixing rod 401 extends and closes the pressure relief hole 207 at the same time, so that the hydraulic chamber 205 forms a closed environment. When the fixing rod 401 continues to go deeper, the internal liquid is compressed, and the fixing rod 401 is pushed back by the hydraulic pressure of the liquid, so that the four fixing rods 401 push the sealing ring seat 4 at the same time, so that the annular sealing ring 402 on the sealing ring seat 4 fits tightly to achieve a high degree of sealing. When the annular sealing ring 402 is slightly deformed, it will not affect the normal closing of the C-shaped rotary valve body 1.

[0029] Furthermore, the middle end surfaces of the front and rear ends of the C-shaped valve core 3 are both provided with chamfered portions 301, so that the C-shaped valve core 3 will not collide with the sealing ring seat 4 when rotating, and the sealing ring seat 4 can be pushed to move by the end surfaces of the chamfered portions 301.

[0030] Working principle: When in use, the C-shaped rotary valve body 1 and the hydraulically sealed valve body 2 are threadedly connected and fixed by means of bolts 203 passing through the connecting ring 202 and inserted into the threaded hole 101, so that the C-shaped rotary valve body 1 and the hydraulically sealed valve body 2 are easy to disassemble and the internal components are easy to repair and replace. The C-shaped valve core 3 is driven to rotate by rotating the valve stem 102, so that the C-shaped valve core 3 and the sealing ring seat 4 are fitted to realize the closure of the C-shaped rotary valve body 1. When the C-shaped valve core 3 rotates 90 degrees counterclockwise, the inside of the C-shaped rotary valve body 1 is connected with the hydraulically sealed valve body 2, that is, the C-shaped rotary valve body 1 is opened. When the C-shaped valve core 3 rotates and fits with the sealing ring seat 4, the sealing ring seat 4 is squeezed, so that the fixing rod 401 extends into the hydraulic chamber 205. The fixing rod 401 extends and closes the pressure relief hole 207 at the same time, so that the hydraulic chamber 205 forms a closed environment. When the fixing rod 401 continues to go deeper, it compresses the internal liquid and pushes the fixing rod 401 back through the hydraulic pressure of the liquid, so that the four fixing rods 401 push the sealing ring seat 4 at the same time, so that the annular sealing ring 402 on the sealing ring seat 4 fits tightly to achieve a high degree of sealing. When the annular sealing ring 402 is slightly deformed, it will not affect the normal closing of the C-shaped rotary valve body 1.
