Description

端面密封蝶阀
技术领域
本发明涉及一种阀门，具体涉及一种端面密封蝶阀。
背景技术
端面密封蝶阀作为简单可靠的调节阀，大量的使用在液体、气体等场合，由于端面密封蝶阀中依靠阀板和阀座间的密封接触起到关闭的功能，为保证其密封性，传统的阀座和阀体为一体结构，采用铸造一体成型，工艺复杂，成本较高，同时由于端面密封蝶阀动作频繁，阀板和阀座间长期摩擦容易磨损变形，最终导致密闭失效。
发明内容
本发明针对现有技术的不足，提出一种阀座和阀体间采用焊接方式连接，使生产工艺更加简单，密封效果更好，生产成本更低的端面封闭蝶阀。具体技术方案如下：
一种端面密封蝶阀，其关键在于：包括阀体、阀板和阀座，所述阀板上侧连接有上转动轴，该上转动轴穿出所述阀体和安装在阀体上部的上转动座活动连接，所述阀板的下侧连接有下转动轴，该下转动轴穿过所述阀体和安装在该阀体下部的下转动座活动连接；
所述阀座由半圆弧形的阀座a和半圆弧形的阀座b组成,该阀座a和阀座b分别焊接在阀体左右两边的内壁上，且所述阀座a和阀座b分别位于所述阀板的两侧。
本发明是这样实现的：将上转动轴可控制机构，如手柄，电机、气动机构等相连，通过控制上转动轴转动，使阀板和阀座接触或者分开，实现开启或者关闭本发明的目的。阀体可用钢板采用卷板工艺生产，让后将阀座焊接在阀板，阀体不用采用传统的铸造一体成型工艺，结构简单，成本也更低。
为更好的实现本发明，可进一步为：
所述阀座截面为圆形，可和阀板配合得更加紧密，同时圆形加工简单，和阀板也更容易进行密封配合。
所述阀板上侧通过抱箍和上转动轴相连，所述阀板的下侧通过抱箍和下转动轴相连。所述阀板采用抱箍与上转动轴和下转动轴连接，使其结构简单，连接牢固，同时也方便拆卸和更换上转动轴和下转动轴。
所述阀体为圆形。采用圆形结构结构简单，简化了加工工艺，同时能更好的其他设备配合使用。
所述上转动轴和上转动座通过轴承活动连接，该下转动轴和下转动座通过轴承活动连接。
本发明的有益效果为：阀座和阀体间采用焊接方式连接，而不必铸造一体成形，工艺更加简单，成本更加低廉；阀座采用圆形截面，使其和阀板配合更加紧密，延长使用寿命。
附图说明
图1为本发明剖视图；
图2为图1中的A-A剖视图。
具体实施方式
下面结合附图及具体实施例对本发明作进一步详细说明。
如图1和图2所示：一种端面密封蝶阀，其关键在于：包括圆形阀体1、阀板2和阀座3，所述阀板2上侧通过抱箍连接有上转动轴，该上转动轴穿出所述阀体1和安装在阀体1上部的上转动座4通过轴承活动连接，所述阀板2的下侧通过抱箍连接有下转动轴，该下转动轴穿过所述阀体1和安装在该阀体1下部的下转动座5通过轴承活动连接；
所述阀座3由半圆弧形的阀座a和半圆弧形的阀座b组成,该阀座3截面为圆形，该阀座a和阀座b分别焊接在阀体1左右两边的内壁上，且所述阀座a和阀座b不在同一水平面上，该阀座a和阀座b分别位于所述阀板2的两侧。
本发明是这样实现的：将上转动轴和手柄、气动控制机构、电动控制机构等控制机构相连，转动上转动轴，在阀板2和阀座3相分开时，开启端面密封蝶阀；在阀板2和阀座3相接触，处于密封状态时，关闭端面密封蝶阀。在阀板2转动过程中，下转动轴跟随着在下转动座5中转动，同时固定阀板2，使其平稳转动。
