Abstract

本实用新型公开了一种气体输送卸灰阀，包括插板阀，气体输送卸灰桶，在气体输送卸灰桶上接有气体输送管，在插板阀和气体输送卸灰桶之间接有蝶阀。本实用新型具有如下的有益效果，一是在插板阀和气体输送卸灰桶之间加有蝶阀，由于蝶阀的气密性能好，使气体输送卸灰桶内的灰体不能进入到插板阀中，保证插板阀的运行，不易损坏，使用寿命长，故障率低，在气体输送卸灰桶内无压力下降，卸灰效果好；二是蝶阀的密封是采用动态密封，当阀门打开时，密封活塞环泄压，开启灵活；当阀门关闭后，密封活塞环加压，密封性能好。

Description

气体输送卸灰阀 
技术领域
本实用新型涉及一种卸灰阀。 
背景技术
在冶金、化工、石灰烧制和水泥生产中所使用的气体输送卸灰阀，是由插板阀和气体输送卸灰桶组成，在气体输送卸灰桶上接有气体输送管，在卸灰过程中，先将插板阀打开，灰体从灰斗中落到气体输送卸灰桶内，再关闭插板阀，气体输送管打开，高压气体将气体输送卸灰桶内的灰体从气体输送管中带走，因此阀体内压力较高，一般在0.5pa以上，由于插板阀的气密性能较差，一是阀体内的灰体进入到插板阀体内，造成插板阀卡死，损坏，不能运行；二是气体从插板阀反冲到灰斗，造成压力下降，影响卸灰效果。 
实用新型内容
本实用新型的目的是提供一种高密封性的气体输送卸灰阀。 
本实用新型的目的是通过如下方式实现的：一种气体输送卸灰阀，包括插板阀，气体输送卸灰桶，在气体输送卸灰桶上接有气体输送管，在插板阀和气体输送卸灰桶之间接有蝶阀。 
所述的蝶阀是动态密封蝶阀，由蝶阀体、蝶阀板转轴和电机组成，蝶阀板通过联接板装有转轴上，电机与转轴联接；在蝶阀体与转轴连接处装有密封块；在蝶阀板外缘面上开有蝶阀板环槽，在蝶阀板环槽内有蝶阀板密封活塞环，蝶阀流体加压管从转轴一端进入，并通过蝶阀板连通蝶阀板环槽，在蝶阀流体加压管有接头。 
本实用新型具有如下的有益效果，一是在插板阀和气体输送卸灰桶之间加有蝶阀，由于蝶阀的气密性能好，使气体输送卸灰桶内的灰体不能进入到插板阀中，保证插板阀的运行，不易损坏，使用寿命长，故障率低，在气体输送卸灰桶内无压力下降，卸灰效果好；二是蝶阀的密封是采用动态密封， 
当阀门打开时，密封活塞环泄压，开启灵活；当阀门关闭后，密封活塞环加压，密封性能好。

具体实施方式
如图1、图2、图3、图4、图5所示，一种气体输送卸灰阀，包括插板阀，气体输送卸灰桶2，在气体输送卸灰桶2上接有气体输送管3，在插板阀和气体输送卸灰桶2之间接有蝶阀。所述的插板阀，由插板阀体1、插板4、气缸8、气缸伸缩杆7组成，气缸伸缩杆7通过联接器6与插板4联接；在插板阀体1外侧壁与插板4连接处装有密封块5；所述的蝶阀是动态密封蝶阀，由蝶阀体9、蝶阀板16转轴10和电机15组成，蝶阀板16通过联接板11装有转轴10上，电机15与转轴10联接；在蝶阀体9与转轴10连接处装有密封块12；在蝶阀板16外缘面上开有蝶阀板环槽17，在蝶阀板环槽17内有蝶阀板密封活塞环14，蝶阀流体加压管18从转轴10一端进入，并通过蝶阀板16连通蝶阀板环槽17，在蝶阀流体加压管18有接头13。 
本实用新型的工作原理： 
由于气体卸灰阀要求在阀门停止工作时，也就是气体输送工作时，整个压力区内不得有任何传动轴及相对运动的摩擦面，否则一是往外冒灰；二是传动部位卡死。而本实用新型在工作时，蝶阀先打开，然后插板阀打开，灰体落入到气体输送卸灰桶2中，插板阀先关闭，然后蝶阀关闭，这时，压力区内无任何传动零件及相对运动的摩擦面，这时，打开气体输送管3上的阀门开启，高压气体进入气体输送卸灰桶2中，将灰体带走。由于在蝶阀打开、关闭过程中，无灰体通过，实现蝶阀的洁净运行，蝶阀的磨损小，使用寿命长；并 且蝶阀是动态密封，在蝶阀板16关闭后，密封活塞环14由蝶阀流体加压管18输入的液体进入蝶阀板环槽17中对密封活塞环14加压，使密封活塞环14紧压在与蝶阀体9内壁上，保证，蝶阀板16的密封性能，灰体不能从蝶阀进入到插板阀，保证插板阀的运行，不易损坏，使用寿命长，故障率低，在气体输送卸灰桶内无压力下降，卸灰效果好；当蝶阀板16打开时，液体从蝶阀流体加压管18汇出，密封活塞环14泄压，蝶阀板16开启灵活。
