The feed port and the different discharge ports are communicated through the connecting hole of the reversing valve core and the different discharge ports, so as to realize the conduction of the feed port and the different discharge ports, achieve the purpose of controlling the material delivery to different pipelines, and the discharge check valve at each discharge port is opened to realize the discharge, while the discharge check valve at the discharge port not communicated with the connecting hole is closed to avoid the mixing of materials due to the gap between the reversing valve core and the valve body affecting the sealing, and also avoid the backflow of materials. It is convenient to use, easy to control, and has strong practicability. Moreover, the discharge check valve is arranged outside the valve body, which can effectively reduce the manufacturing difficulty and is also beneficial to the later maintenance.

[0025] In the embodiment, the discharge check valve 300 comprises a sleeve 310 connected to the connecting hole, a guide sleeve 320 is sleeved in the sleeve, the inward end of the sleeve is provided with a check valve core 330 entering or exiting the guide sleeve by reciprocating motion to control the opening and closing of the hole of the guide sleeve, and the outer periphery of the check valve core is provided with a sealing ring A 331. When the check valve core 330 moves outwardly into the guide sleeve, the hole of the guide sleeve is cut off, and the material cannot be discharged through the guide sleeve. When the check valve core 330 moves inwardly out of the guide sleeve, the hole of the guide sleeve is communicated, and the material can be discharged through the guide sleeve.

[0026] In the embodiment, in order to facilitate the outward movement of the check valve core, the inward end of the check valve core is connected with a ball A 340 which can slide relative to the sleeve and abut against the reversing valve core, and the outer periphery of the ball A is provided with a material passing groove A 341. When the connecting hole is not aligned with the discharge port, the ball A 340 abuts against the circumferential surface of the reversing valve core, the circumferential surface outwardly pushes the ball A, so that the check valve core moves outwardly to close the discharge check valve. The inward end of the check valve core is provided with a threaded portion, and the ball A is threadedly connected together with the threaded portion.

[0027] In the embodiment, the guide sleeve is provided with a spring A350 for pushing the one-way valve core inward to exit the guide sleeve. The spring A350 always provides the one-way valve core with a pushing force for moving inward, when the connecting hole is aligned with the discharge port, the reversing valve core circumferential surface releases the pushing of the ball A340, the whole one-way valve core moves inward together with the ball A, the ball A extends into the connecting hole toward the side of the connecting hole, leaving space for the one-way valve core to move inward, and the ball A abuts against the orifice of the connecting hole.

[0028] In the embodiment, in order to ensure the operation of the one-way valve core, the outward end of the one-way valve core is connected with a guide block A360 extending into the guide sleeve and slidingly fitted with the guide sleeve, and the guide block A is provided with a material passing through hole A361.

[0029] In the embodiment, in order to limit the outward movement position of the one-way valve core, the guide sleeve is internally sleeved with a limiting sleeve 370 for stopping the guide block A to limit the outward sliding distance thereof; when the limiting sleeve 370 abuts against the guide block A, the one-way valve core cannot continue to move outward, and damage caused by the ball A being pushed into the guide sleeve due to excessive material pressure can be avoided.

[0030] In the embodiment, in order to increase the inward movement stroke of the one-way valve core, the side of the reversing valve core is provided with a cut groove 230 at the orifice of the connecting hole, so that the ball A can extend outward the sleeve more distance. By using the circumferential surface of the reversing valve core 200, the cut groove 230 on the connecting hole and the spring A350, the ball A340 is used to jointly control the whole inward or outward movement of the one-way valve core 330 in the discharge one-way valve 300 to realize the discharge or closing operation.

[0031] In the embodiment, the number of the abutting holes 210 is the same as the number of the discharge ports 110 and is uniformly distributed in the circumference, all the abutting holes are connected with the channel 240, the valve body is further provided with a safety valve port 130, the abutting holes are selectively connected with the feeding port or the safety valve port through the rotation of the reversing valve core, and the safety valve port is connected with a safety valve 400; the safety valve port and the safety valve are arranged to timely release pressure when failure or blockage occurs.

[0032] In the embodiment, the safety valve comprises an outer pipe shell 410, an inner guide sleeve provided at the inward end of the outer pipe shell, and a safety valve core 420 for entering or exiting the inner guide sleeve through reciprocating motion to control the opening and closing of the inner hole of the inner guide sleeve, and a sealing ring B421 provided on the outer circumferential surface of the safety valve core. When the safety valve core 420 moves outward to exit the inner guide sleeve, the inner hole of the inner guide sleeve is opened, and the material can be discharged through the inner guide sleeve; when the safety valve core 420 moves inward to enter the inner guide sleeve, the inner hole of the inner guide sleeve is closed, and the material cannot be discharged through the inner guide sleeve.

[0033] In the embodiment, the safety valve core is connected with a guide block B430 at the inward end, the guide block B430 extends into the inner guide sleeve and is in sliding fit with the inner guide sleeve, the guide block B is provided with a material passing hole B; the safety valve core is connected with a ball B440 at the outward end, the ball B440 is provided with a material passing groove B at the outer periphery, the outer pipe shell is provided with a spring B450 which pushes the ball B inward to make the safety valve core enter the inner guide sleeve. The spring B450 always provides a pushing force for the safety valve core to move inward to make the safety valve 400 close; when the material pressure in the reversing valve core exceeds the set value, the material pressure pushes the safety valve core outward to compress the spring B450, and then forces the safety valve 400 to open.

[0034] In the embodiment, the outer pipe shell 410 is internally provided with a snap ring at the inward end, the snap ring is blocked at the end of the inner guide sleeve, and the snap ring also limits the inward movement distance of the guide block B430.
