Plug member of gas valve

A plug member of a gas valve, having an axial bore located in an axial direction thereof, a first bore, and a second bore, which are located in a radial direction thereof, wherein the first bore and the second bore communicate with the axial bore, respectively;

• a cross-sectional diameter of the first bore is larger than a cross-sectional diameter of the second bore;
• the plug member is characterized in that:
• a first guiding slot and a second guiding slot are recessed into an outer peripheral surface of the plug member, wherein the first guiding slot extends from the first bore to the second bore, and has a first end and a second end;
• the first end communicates with the first bore;
• the second end is near the second bore without physically communicating with the second bore;
• a width of the first guiding slot on the outer peripheral surface of the plug member decreases gradually from the first end to the second end;
• the second guiding slot extends from the second bore to the first bore, and has a third end and a fourth end;
• the third end communicates with the second bore;
• the fourth end is located between the first end and the second end of the first guiding slot without physically communicating with the first guiding slot, wherein the width of the second end of the first guiding slot converges to a pointed tip on the outer peripheral surface of the plug member.
