Abstract

The invention discloses a steam regulating valve and belongs to the field of steam valve engineering. A regulating valve seat of the steam regulating valve is provided with a steam exhaust chamber; a regulating valve sleeve is coaxially and fixedly installed in the steam exhaust chamber; the side wall of the regulating valve sleeve is provided with two opposite steam exhaust openings; a regulating valve core movably passes through the two steam exhaust openings and the regulating valve seat; a first regulating valve and a second regulating valve are matched with two steam exhaust openings respectively; the regulating valve core is provided with a first spacing member and a second spacing member; when the first regulating valve and the second regulating valve are closely installed on the two steam exhaust openings, the first spacing member is butted with the inner wall of the steam exhaust chamber; movable gap is provided between the second spacing member and the inner wall of the steam exhaust chamber; the area of the first regulating valve is larger than that of the second regulating valve. When the external driving force becomes invalid, the steam regulating valve can be automatically shut down to protect the whole steamed device, prolong the service life of the steamed device and prevent safety accidents from happening.

Description

technical field [0001] The invention relates to the field of steam valve engineering, in particular to a steam regulating valve. Background technique [0002] The steam regulating valve is a valve widely used in the field of steam engineering. Its main function is to adjust the opening of the valve to realize the adjustment of the steam flow, so as to meet the different steam flow requirements of the steam equipment under different working conditions. demand. [0003] The structure of the existing steam regulating valve is relatively similar. The main structure includes a regulating valve seat, a regulating valve sleeve, a regulating valve and a regulating valve core. The valve sleeve has a steam inlet and an exhaust port connected to each other. The regulating valve can be opened and closed on the steam exhaust port. One end of the regulating valve core is fixedly connected with the regulating valve, and the other end of the regulating valve core slides through the regulat...
