Propane dehydrogenation reactor valve with long service life

Abstract

The invention discloses a propane dehydrogenation reactor valve with long service life. The valve comprises a valve body, valve plates, inclined panels and a valve rod; two valve seats are symmetrically arranged in the valve body, and an included angle is formed between the two valve seats; the two valve plates are arranged up and down in the mode that valve plate sealing rings face outwards and arranged between the two valve seats in a sliding mode; the two inclined panels are arranged in inclined panel grooves of the valve plates correspondingly, and the two inclined panels are in floating connection through a steel ball; the valve rod is connected with the inclined panels; and when the valve rod moves, the valve plates are driven to move through the inclined panels, after the valve plates move in place, the valve plate sealing rings are pushed to be pressed on the valve seats under the action of the inclined panels, and closing of the valve is completed. According to the propane dehydrogenation reactor valve with the long service life, the valve is closed and opened in the mode that the valve plate sealing rings are pressed on the valve seats, the sliding friction problem of the valve plate sealing rings and the valve seats in the closing and opening process of an existing valve is avoided, and even if the valve works under the working condition of frequent closing and opening for a long time, the service life is still very long.

Description

technical field [0001] The invention relates to the technical field of valves used in the petrochemical industry, in particular to a long-life propane dehydrogenation reactor valve. Background technique [0002] When the propane dehydrogenation reactor uses a valve to work, it has the characteristics of high sealing requirements for the working medium, high working temperature, and frequent movements. When the conventional valve is used in the propane dehydrogenation reactor, the valve is frequently closed and opened. At the same time, under the action of high temperature, it will cause wear and leakage between the valve core and the valve seat in a short period of time, so there is a problem that the working medium cannot be completely shut off. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the present invention discloses a valve for a long-life propane dehydrogenation reactor, which includes a valve body, a valve p...

When the conventional valve is used in the propane dehydrogenation reactor, the valve is frequently closed and opened. There is sliding movement wear between the valves, and at the same time, under the action of high temperature, it will cause wear and leakage between the valve core and the valve seat in a short period of time, so there is a problem that the working medium cannot be completely shut off
