Baiting valve and reactor

Abstract

The invention discloses a discharge valve and a reactor. The discharge valve comprises a valve body (1), an end cover (2), a sealing cover (4) and a valve stem (5). The first end of the valve body is provided with Inlet (6), the second end of the valve body is provided with an end cover, the inner end of the valve stem is located in the valve body, and is connected with the sealing cover, and the outer end of the valve stem protrudes outward through the end cover, wherein the sealing The cover is arranged towards the feed inlet and is formed with a protrusion (41) protruding towards the feed inlet. Under the push of the valve stem, the sealing cover blocks the feed inlet, and the protrusion is inserted into the feed inlet and feeds the material. The material in the mouth is pushed out. Before the sealing cover cooperates with the valve seat to block the feeding port, the protruding part pushes the material in the feeding port outward, so that the discharge valve avoids the problem of material jamming on the sealing surface and enhances the sealing performance of the discharging valve.

Description

technical field [0001] The invention relates to a control valve for material discharge, in particular to a discharge valve and a reactor. Background technique [0002] The discharge valve is mainly used for bottom discharge of reactors, storage tanks and other containers. By means of the bottom flange of the valve, it is welded to the bottom of storage tanks and other containers, thus eliminating the residual phenomenon of process medium usually at the outlet of the container. [0003] In the continuous reforming catalyst production process, the shape of the catalyst is an alumina pellet with a diameter of Φ1.2mm. The production process needs to go through processes such as roasting and activation. The material temperature reaches about 550 ° C ~ 600 ° C, and the reactor pressure is about 3Kg / cm 2 , If the valve at the bottom of the reactor uses a high-temperature ball valve, it is expensive, and the valve has high-temperature deformation and leakage; if an ordinary high-tem...

Problems solved by technology

[0003] In the continuous reforming catalyst production process, the shape of the catalyst is an alumina pellet with a diameter of Φ1.2mm. The production process needs to go through processes such as roasting and activation. The material temperature reaches about 550 ° C ~ 600 ° C, and the reactor pressure is about 3Kg / cm 2 , if the valve at the bottom of the reactor uses a high-temperature ball valve, the price is expensive, and the valve has high-temperature deformation and leakage; if an ordinary high-temperature discharge valve or a stop valve, and a high-temperature gate valve are used, there will be ball jamming on the sealing surface

The service life of the above valves is often less than one month
