Abstract
The invention provides a novel double-flow-direction cut-off regulating valve sealing device and an application method. The double-flow-direction balanced sealing and guiding sealing technology is adopted. The novel double-flow-direction cut-off regulating valve sealing device and the application method overcome the defects of the current technology. The novel double-flow-direction cut-off regulating valve sealing device is formed by connecting two large parts, namely, a double-direction balanced sealing guiding set and a composite valve element sealing set. The double-direction balanced sealing guiding set is fixed to a guide part at the upper end of a cylindrical valve element through the cooperation of an internal thread of a fixed gland and an external thread on the cylindrical valve element. The composite valve element sealing set is fixed to the bottom of the cylindrical valve element. On the composite valve element sealing set, a flexible sealing layer is pressed on and fixed to a rigid sealing layer through fastening screws.
