The sealing cover 806 is preferably arranged in the accommodating box 102 instead of being selectively arranged in the first inlet section 801, and this arrangement has an advantage that when the cylinder 805 is retracted to cause the sealing cover 806 to close the steam discharge port 110, the inner wall surface of the accommodating box 102 abuts against the sealing cover 806, and when the pressure of the gas (e.g. the pressure of the steam) inside the accommodating box 102 is applied to the sealing cover 806, the accommodating box 102 can limit the sealing cover 806, so that the pressure of the gas can be prevented from being transmitted to the gas pressure through the sealing cover, and the axial direction of the first inlet section 801 can be prevented from bearing the pressure in the accommodating box 102. If the sealing cover 806 is disposed in the first inlet section 801, when the sealing cover 806 loses the restraining effect of other restraining parts after closing the steam discharge port 110 by the cylinder 805, the pressure in the accommodating case 102 acts on the cylinder 805 through the sealing cover 806, and the cylinder 805 transmits the force to the first inlet section 801, which may have an adverse effect of damaging the first inlet section 801.
