Abstract

一种变压器压力释放阀,涉及一种用于调节变压 器内部压力的保护装置。由壳体、弹簧、压杆等组成, 本阀将泄压过程由活塞式改为气门式,喷油过程由翻 喷式改为平喷式,密封圈由O型改为乳锥状,且由一 道密封改为两道密封。变压器油箱内压力达到一定 限度时,能自动释放,具有体积小,重量轻,安装方便, 性能稳定可靠等优点,是各种变压器的重要组件。

Description

本实用新型涉及一种用于调节变压器内部压力的保护装置。
目前,国内外生产的压力释放阀,都存在着体积大,安装使用极不方便,时效性能不稳定等缺点,在中国专利局CN2040977U号公报中,公布了一种变压器压力释放阀的实用新型专利,但也存在着体积较大,密封不很理想等缺陷。
本实用新型的目的在于克服上述现有技术的不足之处而提供一种变压器压力释放阀。
本实用新型的技术方案是这样实现的:将泄压过程由活塞式改为气门式,喷油过程由翻喷式改为平喷式,密封圈由O型改为乳锥状,且由一道密封改为两道密封。
本实用新型具有体积小,重量轻,安装方便,性能稳定,可靠等优点,是各种变压器的重要组件。
下面结合附图对本实用新型进一步详述:
见附图(结构示意图),本实用新型由紧定螺钉(1),(4),密封圈(2)、(7),壳体(3),弹簧(5),壳体盖(6),信号盖(8),压杆(9),塞罩(10),壳体座(11),螺母(12)组成。螺母(12)通过螺纹与壳体座(11)连接,在壳体座(11)与螺母(12)端面处衬以乳锥状密封圈(2),壳体(3)下部通过若干个径向固定的紧定螺钉(1)与壳体座(11)连为一整体,壳体(3)上部与壳体盖(6)螺纹连为一整体,径向固定的紧定螺钉(4)用于两者的定位,壳体(3)径向有通孔,压杆(9)穿过壳体(3)与壳体盖(6)的园孔,其压杆(9)底部与罩盖在壳体座(11)的顶部的塞罩(10)固定连接,在塞罩(10)与壳体座(11)接缝的轴向端面及园周端面均衬以乳锥状密封圈(2),密封圈(7)衬在压杆(9)与壳体盖(6)之间,压杆(9)顶部为外螺纹,通过螺纹与信号盖(8)连接,壳体盖(6)顶部为六方形,弹簧(5)套在压杆(9)上,且夹压在塞罩(10)与壳体盖(6)之间的壳体(3)空腔中。
当变压器油箱内压力达到一定限度时,克服弹簧(5)的弹力,顶开塞罩(10),气体通过壳体(3)径向的通孔排出。螺母(12)直接螺纹连接于变压器箱盖的注油孔上。
