Description
Technical field
The utility model relates to a kind of fume emission mouth closed unit, is specifically related to a kind of cement industry with high temperature heavy caliber fume pipe import closed unit.
Background technique
Cement industry with the operating ambient temperature of high temperature heavy caliber fume pipe import closed unit more than 550 ℃; External leakage requires very high generally 0～0.3%, bore big (generally more than 2000mm, maximum can reach 5000mm); Usually adopt welding high temperature ventilation butterfly valve to replace using at present; But ventilation butterfly valve leak-down rate is very big, between 1.5%～2.5, can't satisfy the low requirement of leaking; If adopt high temperature heavy caliber fume pipe import closed unit, though can reach seal request, because of it is a negative pressure, pipeline internal medium is to valve gap suction; Pipeline area is big more, and suction is big more, and negative pressure is big more; Suction is big more, thereby the opening force that needs is very big, and the cost of the big more driver part of hoisting capacity is high more.The present domestic special-purpose closed unit of high temperature heavy caliber fume pipe import that a kind of resistance to high temperature is strong, sealing is reliable, cost performance is high that lacks.
Summary of the invention
The purpose of the utility model is in order to solve the deficiency of existing technology, provides a kind of resistance to high temperature is strong, sealing is reliable, cost performance is high cement industry with high temperature heavy caliber fume pipe import closed unit.
The technological scheme of the utility model is: a kind of cement industry comprises valve body, valve gap, arm of force assembly, support unit, bearing pin, Sealing, driver part, high-temperature-resistant layer and pressure release parts with high temperature heavy caliber fume pipe import closed unit, and said valve body internal orifice is provided with the sealing inclined-plane; The valve body upper-end surface is provided with mounting groove, is provided with Sealing in the mounting groove, and said sealing inclined-plane and mounting groove inwall are lined with high-temperature-resistant layer; Said sealing inclined-plane is lined with high-temperature-resistant layer with the lower plane that contacts with Sealing; Said valve gap is connected with arm of force assembly through bearing pin, and pin shaft hole is a U type pin-and-hole, and said pressure release parts are installed on the valve gap; The pressure release parts comprise pressure release parts valve gap; Pressure release parts valve gap is connected with arm component, and arm of force assembly is connected with support unit, and support unit is connected with driver part.
As preferably, said support unit comprises transmission shaft, bearing support and selfaligning bearing, on the said bearing support selfaligning bearing is installed, and is provided with transmission shaft in the selfaligning bearing, and transmission shaft is connected with said arm of force assembly.
As preferably, said driver part is any drive form in hydraulic driving, YE, electric pushrod or the electric reducer.
As preferably, said bearing pin material is that heat resistant and wear resistant decreases steel.
As preferably, said Sealing is a large-section high-temperature flexible woven graphite filler.
As preferably, said high-temperature-resistant layer is high temperature resistant, wear-resistant castable.
The utility model working principle is: when valve gap need be opened; The arm of force drives the valve gap of pressure release parts earlier and upwards opens; Make the pressure venting part in the pipeline, the suffered negative-pressure sucking of closed unit valve gap reduces, and when bearing pin moves to upper end, valve gap hanger U type hole, drives valve gap again and upwards opens.
The beneficial effect of the utility model: 1, first pressure release, reduced the active force of negative pressure to valve gap, required opening force has been reduced, the required ouput force of driver part is reduced, thus the manufacture cost of practicing thrift; 2, structural safety is reliable, good seal performance.
