This invention provides a combined injection and extraction steam valve, relating to the field of steam valves, including a collection structure. The collection structure is installed at the bottom of the bottom valve body and is hollow. The top of the side chamber communicates with the interior of the collection structure through a connecting hole, and the interior of the collection structure communicates with the interior of the top structure. After steam is generated inside the bottom valve body, it enters the interior of the collection structure for collection and storage, facilitating the collection of the liquid generated by the steam. Simultaneously, when the steam pressure is high, the pressure can enter the interior of the side chamber through the connecting hole, causing the piston plate to move downwards. This compresses the spring through the lower pressure rod and the force plate structure, relieving pressure. When the pressure is excessive, the piston plate moves excessively to the discharge port position, allowing the steam to be discharged through the discharge port to release pressure. This solves the problems of common combined injection and extraction steam valves where steam generates liquid, liquid collection and processing are laborious, and steam pressure is excessive.
