the stop section is provided with an air leakage part, the air leakage part is formed by an L-shaped notch arranged on the stop section, the L-shaped notch comprises two communication notches, namely a communication notch a and a communication notch b, when the valve plug stops the valve body, an air leakage hole arranged on the valve body is opposite to the communication notch a, and the communication notch b is communicated with the negative pressure forming cavity; at the moment, the airflow entering the negative pressure forming cavity through the vent hole is led out through the communication notch b, the communication notch a and the air leakage hole in sequence.
8. The high flow rate gas valve according to claim 1, wherein the negative pressure port is disposed along a longitudinal direction of the valve body, and a through-section of the negative pressure port and the gap mounting hole is disposed coaxially with respect to a through-section of the negative pressure forming cavity and the gap mounting hole.
9. The high-flow gas valve according to claim 8, wherein two of said vent holes are installed in an inverted Y-shape on the lower end surface of the valve body and are communicated with said negative pressure forming cavity.
10. The high flow gas valve according to claim 8, wherein the connecting portion is provided with a guide block, the gap mounting hole is provided with a guide groove at a position corresponding to the guide block, and the guide block is mounted in the guide groove; when the valve plug moves in the gap mounting hole, the valve plug can be guided by the guide block along the guide groove.
