一种SF<sub>6</sub>密度继电器校验仪的气体回收装置

Gas recovery device for SF6 (sulfur fluoride) density relay calibrator

Abstract

本实用新型涉及一种SF6密度继电器校验仪的气体回收装置,由以下部分组成:工作气缸通过阀门一与SF6密度继电器连接,回收气缸通过阀门三与SF6密度继电器连接,回收气缸与工作气缸通过阀门二和SF6气体过滤器连接。本实用新型可以在密度继电器校验仪进行工作之后回收SF6气体,既节省了购买SF6气体的开销,又避免气体泄漏对环境的损坏,易于实现,效果明显。
The utility model relates to a gas recovery device for an SF6 (sulfur fluoride) density relay calibrator, which comprises an operation cylinder and a recovery cylinder, wherein the operation cylinder is connected with an SF6 density relay through a valve 1, the recovery cylinder is connected with the SF6 density relay through a valve 3, and the recovery cylinder and the operation cylinder are connected with an SF6 gas filter through a valve 2. The gas recovery device for the SF6 density relay calibrator can be used for recovering the SF6 gas after the operation of the density relay calibrator, cost for purchasing the SF6 gas is saved, damage to the environment caused by gas leakage can be avoided, and the gas recovery device is easy to be realized and evident in effect.
