A high temperature and corrosion resistant airtight slag discharge valve with temperature measurement

Abstract

The invention provides a high-temperature-resistant corrosion-resistant airtight residue discharge valve with a temperature measurement function and belongs to the technical field of residue dischargevalves. A residue inlet is formed in the top surface of an outer barrel. A residue discharge port is formed in the barrel wall of the outer barrel. A flow guide plate inclined downwards and communicating with the residue discharge port is arranged in the outer barrel. A valve seat is made of ceramics and is arranged below the residue inlet. A valve element is made of ceramics and comprises a valve element bottom, a valve element spherical surface, a valve element inverted arch surface and a valve element arch breaking cone. A valve rod penetrates through the flow guide plate and the bottom surface of the outer barrel. The top end of the valve rod is inserted in a blind hole in the bottom of the valve element. The bottom end of the valve rod is connected with a connecting frame. A plate spring is of a platy structure bending downwards. The ends of the plate spring are mounted on the connecting frame. The bottom of the plate spring is fixed to a lifter. A temperature measurement elementis arranged at the top end of the valve rod. A lead wire penetrates out from the bottom end of the connecting frame along the valve rod to be connected with an external temperature display device. The high-temperature-resistant corrosion-resistant airtight residue discharge valve has the functions of arch caking prevention and arch breaking and also has the advantages of being resistant to high temperature and corrosion, capable of measuring the temperature and good in sealing performance.

Description

technical field [0001] The invention relates to the technical field of slag discharge valves, in particular to a high temperature and corrosion resistant airtight slag discharge valve with temperature measurement. Background technique [0002] my country is the world's largest producer of carbon disulfide, which is widely used in industry. The process of producing carbon disulfide with semi-coke and sulfur as raw materials has the advantages of low raw material cost and high product profit. The solid waste generated in the production process needs to be discharged in time to increase the effective reaction volume, thereby improving production efficiency. The discharge of solid waste is generally through the slag discharge valve. However, the current carbon disulfide slag valve cannot fully meet the needs of production, mainly because sulfur is highly corrosive, and the temperature at the position where the valve core and valve seat are located is relatively high, and the exi...

AI Technical Summary

Problems solved by technology

However, the current carbon disulfide slag valve cannot fully meet the needs of production, mainly because sulfur is highly corrosive, and the temperature at the position where the valve core and valve seat are located is relatively high, and the existing valve core and valve seat are resistant to high temperature corrosion. Insufficient, poor sealing

At the same time, the temperature at the valve core is closely related to the production process as an important parameter, but the current production equipment does not have a device to measure this temperature
