The other end of the valve core main structure 1 is provided with a hollow mating groove 3, and the interior of the hollow mating groove 3 is provided with a safety mating stop groove 4, which has a mating function of stopping when mating. The outer cylindrical surface of the valve core main structure 1 is provided with an integrally formed and circumferentially evenly distributed reinforcement guide mating column 5 on one side close to the safety mating stop groove 4, and the middle position of the width direction of the reinforcement guide mating column 5 is provided with a guide mating limit groove 6 that penetrates the reinforcement guide mating column 5 in the length direction. When in use, it can be used in combination with the guide column set on the valve body, and during the overall use of the exhaust valve, it can ensure that the valve core has better activity stability and higher mating accuracy. The outer side of the reinforced guide matching column 5 is a cylindrical structural surface. The outer cylindrical structural surface of the reinforced guide matching column 5 is provided with an arc-shaped movable buffer matching groove 7 with the same central axis. When in use, it is combined with a buffer ring to make the movement between the outer side and the inner wall of the valve body more precise, and the exhaust accuracy and safety of the exhaust valve are higher when in use. It adopts a brand-new structural design. The valve core body is composed of a cylindrical and spherical structure. Its outer side can be used in conjunction with a valve body with a guide structure by setting a guide structure. The interior is provided with a stop groove to improve the safety of the limit matching. The outer side of its active matching position is provided with an active buffer matching groove. When in use, it can be used in conjunction with a buffer ring, so that the valve core has better stability when in motion, and can cooperate with the valve body to achieve the use requirements of high-precision exhaust control.

[0021] Preferably, the left end face of the reinforcing guide matching column 5 coincides with the left end face of the valve core main body structure 1, so that the overall structural support strength is better and the service life is longer during use.

[0022] Preferably, the edge positions on both sides of the guide matching limit groove 6 are respectively provided with guide rounded corner structures for facilitating assembly, which improves the smoothness during matching activities and effectively reduces wear during the activities.

[0023] Preferably, a movable buffer matching arc surface is provided at the outer edge of the movable buffer matching groove 7, so that the connection fluency is better when the buffer ring is matched at this position, and the matching operation is more convenient.

[0024] Preferably, the length of the reinforcing guide matching column 5 is less than one-third of the length of the valve core main body structure 1, which can reduce the production and processing cost of this structure.
