Abstract

本实用新型涉及一种组合阀,主要解决组合阀介质的品质要求高和造价较高的问题,其特征是:气源导管与过滤器相连,过滤器通过两导管与两电磁阀相连,电磁阀通过导管与球阀相接,进油导管与一球阀相接,然后与出口导管相接,雾化蒸气导管与另一球阀相接,然后与止回阀相接,再与出口导管相接,限位开关通过摇臂与球阀相连。

Description

一种组合阀
本实用新型涉及一种组合阀。
在已有技术中,安装在电沾锅炉燃油系统管路上的组合阀需要实现正常运行、吹扫导管和停止运行等三种状态,目前采用的组合阀是依靠球阀阀芯的不同停角位置来改变球阀阀内通道的方向来完成上述的三种状态,它的缺点是制造精度高,对介质的品质很敏感,容易磨损和泄漏,造价较高。
本实用新型的目的是提供一种对介质的品质要求不高和造价较低的组合阀。
本实用新型由过滤器、电磁阀、限位开关和球阀组成,其特征是:气源导管与过滤器相连,过滤器通过两导管与两电磁阀相连,电磁阀通过导管与球阀相接,进油导管与一球阀相接,然后与出口导管相接,雾化蒸气导管与另一球阀相接,然后与止回阀相接,再与出口导管相接,限位开关通过摇臂与球阀相连。
由于本实用新型采用标准化的电磁阀,由电气信号转换来达到球阀换向,避免了单个球阀因功能多而制造精度太高带来的加工困难、容易磨损和泄漏,本实用新型对介质的品质要求不高,并且造价较低。
下面结合附图对本实用新型作详细说明,
图1是本实用新型正面的结构示意图,
图2是本实用新型反面的结构示意图,
图中,气源导管1与过滤器2相连,过滤器通过两导管与两电磁阀3和4相连,电磁阀通过导管与球阀5和6相接,气源通过过滤器,由电磁阀控制球阀的开和关,进油导管7与一球阀5相接,然后与出口导管相接,雾化蒸气导管8与另一球阀6相接,然后与止回阀9相接,再与出口导管相接,限位开关10通过摇臂11与球阀相连,由限位开关来显示球阀的工作状态,过滤器、导管、电磁阀、球阀、止回阀和限位开关固定在中间的板12上当球阀5处于关闭状态和球阀6处于开启状态时,本实用新型处于吹扫状态,当球阀5处于开启状态和球阀6处于开启状态时,本实用新型处于燃烧状态,当球阀5处于关闭状态和球阀6处于关闭状态时,本实用新型停止使用。
