the diameter of the upper port of the cavity 11 is smaller than that of the valve ball 4;
the upper part of the exhaust seat 2 is provided with an air inlet and outlet, and the air inlet and outlet is provided with a valve core 5;
the valve core 5 is provided with a plurality of upper guide rods 10 and lower guide rods 16, the upper guide rods 10 and the lower guide rods 16 are symmetrically arranged on the upper side and the lower side of the valve core 5, the upper guide rods 10 and the lower guide rods 16 are both vertically connected with the valve core 5, and the plurality of upper guide rods 10 and the plurality of lower guide rods 16 are circularly arranged on the upper side and the lower side of the valve core 5 in an array manner;
the air inlet cover 3 is detachably connected to the exhaust seat 2 through a support rod 12, a second sealing ring 8 is arranged at the joint of the support rod 12 and the exhaust seat 2, and the air inlet cover 3 is not in contact with the exhaust seat 2;
a first guide groove 13 is formed in the lower end of the air inlet cover 3, a first spring 9 is arranged in the first guide groove 13, one end of the first spring 9 is propped against the lower surface of the air inlet cover 3, the other end of the first spring is propped against the upper end of an upper guide rod 10, the upper guide rod 10 is partially arranged in the first guide groove 13, and the minimum upward movement stroke of the upper guide rod 10 can ensure that the valve core 5 is driven to enable the lower end of the valve core 5 to be completely separated from the air inlet and outlet;
a second guide groove 14 is formed in the upper end of the valve seat 1, a second spring 15 is arranged in the second guide groove 14, one end of the second spring 15 is propped against the upper end face of the valve seat 1, the other end of the second spring is propped against the lower end of a lower guide rod 16, the lower guide rod 16 is partially arranged in the second guide groove 14, and the minimum downward movement stroke of the lower guide rod 16 can ensure that the valve core 5 is driven to enable the upper end of the valve core 5 to be completely separated from the air inlet and outlet;
