Description

一种蝶式气动程控阀体
技术领域
本发明属于程控阀技术领域，具体涉及一种蝶式气动程控阀体。
背景技术
程控阀是一种通过气动、液动等方式驱动的切断阀。该阀与DCS集散控制系统或PLC相连，实现计算机程序的远程控制。广泛应用于甲醇裂解制氢、酒精干燥、氯乙烯浓缩回收、多晶硅尾气回收、制氮、制氧、回收二氧化碳等变压吸附气体分离行业。程控阀是变压吸附装置的关键设备、是保证变压吸附各工序顺利完成和系统可靠运转的重要部件。变压吸附的主要工序有吸附、均压、顺放、逆放、冲洗等步骤，每一步工序的完成均是通过程控阀在一定时间的启闭来实现。因而程控阀需要大量的频繁动作，操作要求和性能均高于一般通用阀门。
发明内容
为了克服上述现有技术的不足，本发明的目的是提供一种蝶式气动程控阀体，具有密封性强，能准确表示出阀体内气体流动情况，有较好的流量控制特性。
为了实现上述目的，本发明采用的技术方案是：
一种蝶式气动程控阀体，包括端盖，端盖与连接环通过内六角圆柱头螺钉连接；连接环通过螺钉将端盖和阀体连接在一起；轴套与固定动轴之间设有O形密封圈，从动轴由主动轴带动蝶形阀带动，之间由V形密封圈、O形密封圈、塑料油封体、O形密封圈、石墨垫片、垫环密封，阀体内设有蝶形阀，左端通过键和螺母连接主动轴，右端同种方式连接从动轴；螺母将蝶形阀固定在主动轴上由止动垫圈止动；主动轴连接磁块组合，主动轴带动蝶形阀转动，左端与仪表盘连接，并用内六角锥端紧定螺钉固定，中间通过复合轴承配合轴套进行高效转动；主动轴设有紧钉环，紧钉环通过螺钉连接阀体紧定主动轴。
所述的磁块吸引仪表盘的磁针转动，指示阀体内气体流量。
所述的阀体、蝶形阀采用灰铸铁HT300。
所述的指示盘安装在侧板上。
所述的磁块组合由支架、螺栓、磁块，开槽沉头螺钉，I型六角螺母组合而成。
本发明的有益效果是：
1）阀体采用了垫环，塑料油封体 ，石墨垫片及很多密封圈等起密封作用的零件，阀体密封性强。
2）利用磁块得运动吸引表盘内指针运动，精确度高，能准确表示出阀体内气体流动情况。
3）阀体、蝶形阀强度高，耐磨性好，使用强度高，有效延长阀体寿命。
4）阀门采用对夹式蝶形阀，对夹式蝶阀结构简单、体积小、重量轻，只由少数几个零件组成。而且只需旋转90°即可快速启闭，操作简单，同时该阀门具有良好的流体控制特性。蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体时唯一的阻力，因此通过该阀门所产生的压力降很小，故具有较好的流量控制特性。
附图说明
图1为本发明的结构示意图。
具体实施方式
以下结合附图对本发明进一步叙述。
如图1所示，一种蝶式气动程控阀体，包括端盖1，其特征在于，端盖1与连接环2通过内六角圆柱头螺钉48连接；连接环2通过螺钉将端盖1和阀体12连接在一起；轴套3与固定动轴5之间设有O形密封圈4，从动轴5由主动轴带动蝶形阀13带动，之间由V形密封圈6、O形密封圈7、塑料油封体8、O形密封圈9、石墨垫片10、垫环11密封，阀体12内设有蝶形阀13，左端通过键60和螺母14连接主动轴16，右端同种方式连接从动轴5；螺母14将蝶形阀13固定在主动轴16上由止动垫圈15止动；主动轴16连接磁块41组合，主动轴16带动蝶形阀13转动，左端与仪表盘20连接，并用内六角锥端紧定螺钉56固定，中间通过复合轴承59配合轴套进行高效转动；主动轴16设有紧钉环17，紧钉环17通过螺钉连接阀体12紧定主动轴16。
所述的磁块41吸引仪表盘20的磁针转动，指示阀体内气体流量。
所述的阀体12、蝶形阀13采用灰铸铁HT300。
所述的指示盘20安装在侧板40上。
所述的磁块组合41由支架、螺栓、磁块，开槽沉头螺钉，I型六角螺母组合而成。
端盖1，控制从动轴的轴向定位，起到密封和保护的作用，端盖1与连接环2通过内六角圆柱头螺钉48连接；连接环2，通过螺钉把端盖1和阀体12连接在一起；轴套3，起到固定和支撑从动轴5的作用； O形密封圈4，起到密封作用，防止油脂外泄同时隔离外界物质侵入；从动轴5，由主动轴带动蝶形阀13再带动其一起转动；V形密封圈6，起到密封作用，防止润滑油漏出及外物侵入；7是O形密封圈；塑料油封体8，密封作用，防止润滑油漏出及外物侵入；9是O形密封圈；10是石墨垫片，起到加强密封的作用；垫环11，保证密封系统的可靠；阀体12，覆盖机件，提供稳定密封的环境，并支撑内部零件；蝶形阀13，通过转动角度改变控制管道开放大小来控制气体流量及流速，左端通过键60和螺母14连接主动轴，右端同种方式连接从动轴5；螺母14，将蝶形阀固定在主动轴16上；止动垫圈15，防止螺母14松动，稳固蝶形阀13；主动轴16，连接摇臂19和41磁块组合，右端与蝶形阀13相连，驱动蝶形阀转动，左端与仪表盘20连接，并用内六角锥端紧定螺钉56固定，中间通过复合轴承59配合轴套进行高效转动；紧钉环17，其作用是紧定主动轴16，使其稳固工作；20是指示盘，可以显示阀体内气体流量。
本发明的工作原理是：
利用动力输出装置带动主动轴转动，主动轴与蝶形阀相连，带动蝶形阀做旋转运动，蝶形阀带动从动轴。阀体旋转，在蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为0°-90°之间，旋转到90°时，阀门则牌全开状态。另一方面，摇臂带动磁块组合转动，仪表盘指数随之改变，便于操作者根据实际情况控制阀体内气体的流量。
