AI Technical Summary

Technical Problem

Existing high-temperature angle stroke valves are prone to blowing out of the valve stem in high temperature environments, causing the catalyst to enter the bearing and causing failure.

Method used

An angle stroke valve for high-temperature catalyst is designed. By setting an anti-blowing gear ring, an upper bearing and a valve stem sealing ring between the valve stem and the valve body, and fixing and limiting the valve stem with anti-blowing bolts and limiting columns to prevent the valve stem from blowing out. At the same time, a valve stem sealing ring is added below the upper bearing to prevent the catalyst from entering.

Benefits of technology

It effectively prevents the valve stem from blowing out, enhances the reliability of the connection and structural stability, and prevents the catalyst from entering the bearing, extending the service life.

Abstract

The angular travel valve comprises a valve body, a valve seat, an upper valve rod, a lower valve rod and a valve plate, a blow-out prevention baffle ring, an upper bearing and a valve rod sealing ring are sequentially arranged between the upper valve rod and the valve body from top to bottom in a sleeving mode, and a circle of flange is arranged at the lower end of the upper valve rod; the upper bearing and the valve rod sealing ring are arranged on the valve body, a limiting hole is formed in the anti-blowing-out baffle ring, an anti-blowing-out bolt is connected to the valve body in a threaded mode, a limiting column is arranged at the front end of the anti-blowing-out bolt, the limiting column is clamped in the limiting hole, and the upper bearing and the valve rod sealing ring are clamped between the anti-blowing-out baffle ring and the flange. According to the blow-out prevention check ring, the flange on the upper valve rod is limited through the upper bearing and the valve rod sealing ring, so that blow-out prevention of the upper valve rod is achieved, in addition, the valve rod sealing ring is additionally arranged below the upper bearing for sealing, and particles and dust in media, such as catalysts, can be prevented from entering the bearing position to cause failure.
