Abstract

本实用新型提供了一种排气截油释放阀，所要解决的技术问题是：目前，在全密封变压器上采用变压器油位显示的装置，仅具有油位显示与排气功能，其缺点是不能进行液体的排放，从而不能排泄因变压器故障产生的油、气混合物，因此它不具备保护变压器油箱的功能。本实用新型的要点是：它包括腔体、浮子、阀座、阀罩、膜盘、弹簧、标志杆、衬套，在膜盘安装有用于排气、截油的上下两个针阀，在上针阀的外缘有限位弹簧，使阀在正常工作时能排除腔体内的气体，在浮子和下针阀之间设置配重块。本实用新型的积极效果是：本实用新型与现有技术相比，它将油位显示、油位截止、排气和排泄油气混合物四种功能集于一体，方便实用。

Description

排气截油释放阀
技术领域
本实用新型属于全密封变压器的一种配件或称组件，安装在变压器箱盖上。它除可以显示其油位外，当变压器内部故障时，能及时释放出油箱内过压，避免油箱变形或爆裂。该产品适用于油浸变压器，特别适用于全密封配电变压器。
背景技术
目前，在全密封变压器上采用变压器油位显示的装置，仅具有油位显示与排气功能，其缺点是不能进行液体的排放，从而，不能排泄因变压器故障产生的油、气混合物，因此它不具备保护变压器油箱的功能。
发明内容
本实用新型的目的在于克服上述已有技术的不足而提供结构简单，可靠性高，同时具有油位显示、油位截止、排气和排泄油气混合物四种功能的排气截油释放阀。
本实用新型的目的可通过下述措施来达到：它包括腔体、浮子、阀座、阀罩、膜盘、弹簧、标志杆、衬套，其特征是：在膜盘安装有用于排气、截油的上下两个针阀，在上针阀的外缘有限位弹簧，使阀在正常工作时能排除腔体内的气体，在浮子和下针阀之间设置配重块，当油位上升至设定值时浮子将配重块顶起，从而截止腔体内的液体排除体外，防止液体外泄。当油箱内部故障，油箱内部压力急剧升高时，该阀可将其压力通过膜盘跳起进行释放，从而，该装置即具有油位显示及排气、截油之功效，又具有压力释放的排泄功能。浮子用于显示液位。
本实用新型与现有技术相比，它将油位显示、油位截止、排气和排泄油气混合物四种功能集于一体，方便实用。
附图说明
下面结合附图进一步说明本实用新型。
附图是本实用新型的结构示意图。
具体实施方式
它包括腔体14、浮子15、阀座12、阀罩19、膜盘9、弹簧18、标志杆2、衬套1，在膜盘9安装有用于排气、截油的针阀10及6，在针阀6的外缘有限位弹簧17，使阀在正常工作时能排除腔体14内的气体；当油位上升至设定值时浮子15将配重块1 1顶起，从而截止腔体内的液体排除体外。上针阀6内的顶针5用于阻止外部大气进入体内；闭锁装置20通过螺钉压紧标志杆2、密封垫3和上针阀6，使该装置在设备整体进行密封试验时保证密封良好，其闭锁装置在设备正常运行时拆除。
当油箱内部故障时，油箱内将产生大量气体，油箱内部压力急剧升高。当压力值达到阀的开启压力时，该阀可通过膜盘跳起将压力释放出来，当油箱内压力降到阀的关闭压力值时，阀又可靠关闭，从而保护了电气设备，避免油箱的变形或爆裂。
4是限位管、7和8是密封圈、13是阀座连接套。
