Abstract
A valve structure for use in a vaporizer is provided including: a valve seat 16 confronting a vaporization area Y in which a liquid feedstock 106 is to be vaporized and having a liquid feedstock feeding port 15a for introducing the liquid feedstock 106 into the vaporization area Y, and a valve body 1 movable so as to abut against and depart from the valve seat 16 for opening/closing a flow channel extending from the liquid feedstock feeding port 15a to the vaporization area Y, the valve body 1 being capable of controlling the degree of opening of the flow channel thus opened thereby controlling the flow rate of the liquid feedstock 106 flowing through the flow channel into the vaporization area Y.
