Description

真空偏心变压器蝶阀
技术领域
本发明属于电力设备，特别涉及一种真空偏心变压器蝶阀。
背景技术
变压器蝶阀是变压器油路控制的主要设备之一，其中蝶板与阀体紧密配合形成密封面控制油路的通断，以往的蝶阀通常采用O型环作为密封部件，该部件容易被腐蚀分解，影响使用寿命，阀体多采用铸造件，渗漏比较严重，使用时需经常更换，既浪费人力物力，又影响设备的正常运转。
发明内容
本发明的目的在于克服上述技术不足，提供一种结构简单，使用寿命长，密封性能好的真空偏心变压器蝶阀。
本发明解决技术问题采用的技术方案是：真空偏心变压器蝶阀包括阀体、阀杆、阀杆套、压盖，其特点是阀体端面四角对称设置四个安装连接孔，阀体内孔中分别固定装有两个阀杆套，阀杆套内活动穿装阀杆，阀杆上固定装有蝶板，阀杆穿装在蝶板的偏心孔中，阀体上端加入填料密封，并用压盖压紧，阀杆上端连接驱动装置。
本发明的有益效果是：真空偏心变压器蝶阀结构简单，方便加工，生产成本低，耐腐蚀，不渗漏，密封性能好，大大延长了使用寿命，扩大了蝶阀的使用环境和温度范围，减少了更换次数，大大节约了后期的维修和更换的人力和物力。
附图说明
以下结合附图以实施例具体说明。
图1是真空偏心变压器蝶阀结构主视图。
图2是图1的A-A剖视图。
图中，1-驱动装置；2-压盖；3-阀体；3-1-安装连接孔；4-阀杆；5-蝶板；6-阀杆套。
具体实施方式
实施例，参照附图1~2，真空偏心变压器蝶阀的阀体3端面四角对称设置四个安装连孔3-1，阀体3内孔中分别固定装有两个阀杆套6，阀杆套6内活动穿装阀杆4，阀杆4上固定装有蝶板5，阀杆4穿装在蝶板5的偏心孔中，阀体3上端加入填料密封，并用压盖2压紧，阀杆4上端连接驱动装置1。
真空偏心变压器蝶阀的使用方法是：使用时，真空偏心变压器蝶阀通过阀体3的安装连接孔3-1与变压器油路管道连接，其驱动可采用手动、齿轮驱动、蜗轮蜗杆驱动、气动驱动、液压驱动、电动驱动等形式。驱动装置1传递力矩给阀杆4，阀杆4转动并带动蝶板5一起转动，打开油路管道，使油路接通。当蝶板5与管路方向一致时达到流量最大，当阀杆4反向转动时，使阀体3内过流通道的截面积变小，流量也随之变小，当蝶板5与油路管道直时，整个真空偏心变压器蝶阀关闭，从而实现管路的开闭。
