At the same time, the outer wall of the transverse sealing cylinder 3057 is in close contact with the inner wall of the straight groove 303, the inner wall of the bottom tube 201 and the inner wall of the side tube 202.

Corresponding to the side groove 3053, after the annular piston plate 5067 moves toward the inside of the piston cylinder 3061, it pushes the air inside the piston cylinder 3061 to be pressed into the connecting groove 3054, so that the movable ring 3055 moves toward the side away from the L-shaped through groove 302, so that the rubber sealing ring 3056 is pressed against the inner wall of the spherical valve housing 1, so that the straight groove 303 and the inner wall of the spherical valve housing 1 form a seal, preventing the medium from entering the gap between the spherical valve housing 1 and the rotating ball core 301 during the circulation process, thereby protecting the equipment.

[0021] The decoking nozzle unit 306 includes a piston cylinder 3061 movably mounted inside the oblique groove 304. The outer wall of the piston cylinder 3061 is in close contact with the inner wall of the oblique groove 304. A hemispherical protrusion 3062 is provided at one end of the piston cylinder 3061 close to the L-shaped through groove 302. A jet region 3065 is provided on the side wall of the hemispherical protrusion 3062 close to the side groove 3053. The jet region 3065 is composed of evenly arranged holes. The jet region 3065 corresponds to the side groove 3053. A first sliding block 3063 is symmetrically mounted on the side wall of the piston cylinder 3061. The first sliding block 3063 is slidably connected to the first sliding groove 307. The first sliding block 3063 A first spring 3064 is installed on one side close to the L-shaped through groove 302. Two jet regions 3065 corresponding to the two side grooves 3053 are arranged on the piston cylinder 3061. The two through grooves 303 are arranged vertically, and the piston cylinder 3061 is located on the symmetric axis of the two through grooves 303. When the piston cylinder 3061 enters the L-shaped through groove 302, the two jet regions 3065 face the two through grooves 303 respectively, which facilitates the simultaneous blowing and decoking of the two through grooves 303. It is not necessary to respectively arrange decoking nozzles on the bottom pipe 201 and each side pipe 202, which simplifies the structure of the decoking equipment.

The internal tube 3066 is used to pass decoking gas. A side through groove 3067 is opened on the internal tube 3066 and a baffle 3068 is arranged on the outside. When the transverse sealing cylinder 3057 enters the piston cylinder 3061, the air inside the piston cylinder 3061 cannot enter the inner tube 3066, which facilitates the air to enter the side groove 3053 to complete the compression. When the decoking gas is released, the baffle 3068 can be pushed to move outward, so that the glue-discharging gas passes toward the straight groove 303, which is convenient for compression and decoking.

[0022] The push ventilation assembly 5 includes an oblique cylinder 501 installed at an equal angle on the outer wall of the spherical valve housing 1. The inclination angle of the oblique cylinder 501 is the same as the inclination angle of the oblique groove 304.

The side of the oblique cylinder 501 away from the spherical valve housing 1 is equipped with a ventilation branch pipe 502. The oblique piston column 5061 moves to push the internal air pressure of the connecting groove 3054 to increase, and then the piston cylinder 3061 can be pushed to move so that the jet area 3065 is staggered with the side groove 3053, which is convenient for ensuring that the rubber sealing ring 305 6 is subjected to pressure, and at the same time, the inclined piston column 5061 moves to the bottom of the ventilation branch pipe 502, so as to facilitate the introduction of decoking gas and facilitate decoking. The other ends of the three ventilation branch pipes 502 are connected to the ventilation main pipe 503, one end of the ventilation main pipe 503 is connected to the decoking gas box, and the decoking gas box is used to pass the decoking gas.

[0023] The push-connection unit 506 includes an oblique piston column 5061 movably mounted inside the oblique cylinder 501, the outer wall of the oblique piston column 5061 is in close contact with the inner wall of the oblique cylinder 501, a second sliding plate 5063 is symmetrically mounted on the side wall of the oblique piston column 5061 away from the spherical valve housing 1, the second sliding plate 5063 is slidably connected to the second sliding groove 504, a third spring 5064 is mounted on the side of the second sliding plate 5063 close to the spherical valve housing 1, a bottom block 5062 is mounted on the end of the oblique piston column 5061 away from the spherical valve housing 1, and the oblique piston column 506 An insertion groove 5065 is provided at one end close to the spherical valve housing 1, and a connecting groove 5066 is provided at one end of the insertion groove 5065 away from the spherical valve housing 1. The connecting groove 5066 penetrates to one end of the oblique piston column 5061 away from the spherical valve housing 1, and an annular piston plate 5067 is installed at one end of the insertion groove 5065 close to the spherical valve housing 1. The outer diameter of the oblique piston column 5061 is the same as the inner diameter of the piston cylinder 3061, the inner diameter of the annular piston plate 5067 is the same as the outer diameter of the internal tube 3066, and the outer diameter of the internal tube 3066 is larger than the inner diameter of the connecting groove 5066.

[0024] Working principle: In the device, the vertical through groove 303 inside the rotating ball core 301 corresponds to the bottom tube 201, and the horizontal through groove 303 inside the rotating ball core 301 is on the same horizontal plane as each side tube 202. Turning on the driving motor 4 can drive the rotating ball core 301 to rotate inside the spherical valve housing 1, driving the horizontally arranged through groove 303 to be connected with the side tube 202 at the desired outlet position. When in use, after the medium is introduced from the bottom tube 201, the medium passes through the L-shaped through groove 302 and the two through grooves 303 and passes out from the side tube 202; With the longitudinal axis of the spherical valve housing 1 as the axis, the oblique cylinder 501 corresponds to the side tube 202 on the opposite side. When the rotating ball core 301 rotates until the straight groove 303 is connected to the side tube 202 on one side, the corresponding electromagnet 505 is controlled to be energized to generate a repulsive force on the bottom block 5062, thereby pushing the oblique piston column 5061 to move toward the oblique groove 304, so that the annular piston plate 5067 at the end of the oblique piston column 5061 enters the inner side of the piston cylinder 3061. Since the outer wall of the annular piston plate 5067 is in close contact with the inner wall of the piston cylinder 3061, and the inner wall of the annular piston plate 5067 is in close contact with the outer wall of the internal tube 3066, when the oblique piston column 5061 moves toward the hemispherical protrusion 3062, the air inside the piston cylinder 3061 is pushed from the jet area 3065 into the side groove 3053. After the end of the internal tube 3066 contacts the inner wall of the insertion groove 5065, the oblique piston column 5061 continues to move to push the piston cylinder 3061 toward the L-shaped through groove 302 until the jet area 3065 is separated from the side groove 3053. At the same time, the air is pressed into the connecting groove 3054, pushing the movable ring 3055 to move toward the side of the side tube 202, so that the rubber sealing ring 3056 is in close contact with the inner wall of the spherical valve housing 1, so that the straight groove 303 and the inner wall of the spherical valve housing 1 form a seal, preventing the medium from entering the gap between the spherical valve housing 1 and the rotating ball core 301 during the circulation process. When the movable ring 3055 moves, it drives one end of the transverse sealing cylinder 3057 to enter the inside of the side tube 202, which is convenient for positioning and further forms a seal on the gap between the straight groove 303 and the inner wall of the spherical valve housing 1. After the oblique piston column 5061 moves toward the inside of the oblique groove 304, the oblique piston column 5061 moves to the side of the ventilation branch pipe 502 close to the spherical valve housing 1. When the medium has passed through and it is necessary to decoke the inside of the L-shaped through groove 302, the straight groove 303, the bottom pipe 201 and the side pipe 202, the switch valve between the decoking gas box and the ventilation main pipe 503 is opened. At this time, the decoking gas flows out from the ventilation branch pipe 502 into the oblique cylinder 501, and the decoking gas enters the inside of the internal pipe 3066 through the connecting fine groove 5066, and generates pressure on the two baffles 3068, pushing the baffles 3068 outward. The piston cylinder 3061 moves so that the decoking gas enters the interior of the piston cylinder 3061. Since the holes of the jetting area 3065 are tightly attached to the inner wall of the oblique groove 304, the air pressure inside the piston cylinder 3061 increases continuously, pushing the piston cylinder 3061 toward the interior of the L-shaped through groove 302 until the jetting area 3065 enters the interior of the L-shaped through groove 302, and the two jetting areas 3065 correspond to the two straight grooves 303 respectively. At this time, the decoking gas is ejected from the holes on the two jetting areas 3065 toward the two straight grooves 303, thereby purging and decoking the two straight grooves 303 and the interior of the bottom pipe 201 and the side pipe 202; After decoking is completed, the electromagnet 505 is powered off, the oblique piston column 5061 moves back under the elastic force of the third spring 5064, the piston cylinder 3061 moves back under the elastic force of the first spring 3064, and the movable ring 3055 moves back under the elastic force of the rubber sealing ring 3056, so that the end of the transverse sealing cylinder 3057 moves back to the inside of the straight groove 303.
