Abstract
The utility model discloses a steam regulating valve. The steam regulating valve comprises a bellows component, an angle valve body and a gland, wherein the angle valve body and the gland are mutually connected, and an inner cavity is formed in the angle valve body and the gland and is provided with a valve head; a horizontally arranged first opening and a vertically arranged second opening are formed in the left side of the angle valve body, and an opening and closing structure is formed by the valve head and the mouth part of the right side of the first opening. The steam regulating valve is characterized in that the valve head is formed by performing solution treatment on stainless steel 316, and the sealing surface of the valve head is provided with an abrasion-resistant layer which is made of stellite. According to the steam regulating valve, the valve head is formed by performing solution treatment on the stainless steel 316, the sealing surface of the valve head is provided with the abrasion-resistant layer which is made of the stellite, so that the outer surface of the valve head will not be corroded after the improvement, the sealing surface is not prone to abrasion, and service life is greatly prolonged; besides, a bellows is designed into multiple layers so as to resist high pressure.
