PURPOSE: An automatic ignition valve is provided to prevent a burner from being turned off with rotating a knob because a locked state of a knob shaft is maintained in an initial or ignition position. CONSTITUTION: An automatic ignition valve comprises a valve body(10), a cork(20), and a knob shaft(30). The valve body comprises a gas inlet port(111), a main gas outlet port and a sub gas outlet port. The gas inlet port and the main gas outlet port are formed respectively in an inlet and outlet of a conical type-cork insertion groove(11) The sub gas outlet port is penetrated through the inlet of the cork insertion groove at a right angle. The cork comprises a main passage(212), an inlet passage, a sub passage and a torque pin groove(215). The inlet passage and the sub passage are formed in an upper and an lower part of a horizontal passage(21). The torque pin groove is formed into one body in the inlet of the horizontal passage. A circle type-ring(22) and a gas diverging ring(23) are inserted into a sill(211) of the cork. The other side of a coil spring(25) inserted into one side of a needle pin(24) fits in an inner part of the cork. One side of the coil spring fits in the knob shaft. A torque pin(31) of the knob shaft is inserted into the torque pin groove formed in the other side of the cork in a longitudinal direction.
