Description

压力释放阀
技术领域
本发明涉及一种压力释放阀，属于变压器安全装置技术领域。
背景技术
目前，现有的压力释放阀由于防雨、防潮性能不佳，导致弹簧锈蚀，在喷出压力过大时，弹簧变形后，无法弹回和使用。
发明内容
目的：为了克服现有技术中存在的不足，本发明提供一种压力释放阀。
技术方案：为解决上述技术问题，本发明采用的技术方案为：
一种压力释放阀，包括阀座、胶膜盘、弹簧，还包括安装法兰、护罩、螺杆，所述阀座底部设置有安装法兰，用于便于与储油柜连接；所述阀座顶部设置有胶膜盘，所述胶膜盘顶部与弹簧一端连接，弹簧另一端与护罩内壁相连接；所述阀座两侧设置有安装孔，所述护罩通过螺杆与阀座上的安装孔连接，所述护罩设置于阀座上方。
还包括标志轴，所述标志轴底端与胶膜盘中央顶部相连接，标志轴另一端穿过护罩上的通孔，可沿护罩通孔上下移动。
还包括挡板，所述挡板垂直设置于标志轴侧壁，用于配合弹簧限制胶膜盘上升的距离。
还包括开关触点、接线盒，所述开关触点分别设置于挡板顶面、护罩内壁上；所述接线盒设置于护罩外侧壁上；用于胶膜盘被顶起喷油时，开关触点相导通，并通过接线盒与远程报警系统形成回路。
作为优选方案，还包括橡胶套，所述橡胶套套接于标志轴顶部，用于防止雨水从护罩通孔内流入。
作为优选方案，所述安装法兰直径设置为235mm，用于配合总油量大于31.5t的储油柜。
有益效果：本发明提供的压力释放阀，通过安装法兰的设计，便于现场安装；护罩可有效防雨、防潮；挡板的设计，可有效防止弹簧由于喷出压力过大而变形的风险；并提供了远程监测的接口。
附图说明
图1为本发明的结构示意图。
具体实施方式
下面结合附图对本发明作更进一步的说明。
如图1所示，一种压力释放阀，包括阀座6、胶膜盘4、弹簧3，还包括安装法兰7、护罩2、螺杆5，所述阀座6底部设置有安装法兰7，用于便于与储油柜连接；所述阀座6顶部设置有胶膜盘4，所述胶膜盘4顶部与弹簧3一端连接，弹簧3另一端与护罩2内壁相连接；所述阀座6两侧设置有安装孔，所述护罩2通过螺杆5与阀座6上的安装孔连接，所述护罩2设置于阀座6上方。
还包括标志轴1，所述标志轴1底端与胶膜盘4中央顶部相连接，标志轴1另一端穿过护罩2上的通孔，可沿护罩2通孔上下移动。
