Leaks can occur along the valve stem through the packing or diaphragms. Leaks of this type can be stopped by closing the valve and venting any pressure from the outlet.
泄漏可能沿着阀杆通过衬垫或隔膜发生。关闭阀门，从排气口排出压力可以停止这种泄漏。
After draining, close drain valve.
排泄完毕，关闭排泄阀。
"As thermal expansion conditions develop, pressure builds up to the setting of the relief valve. This will cause discharging of small quantity of water."
随着热量的增加,压力也随着增加,并达到安全阀的压力设置。此时将导致安全阀排泄出少量的水。
which subsequently cause corresponding changes in air pressure throughout the system, resulting in the likely unsealing of traps.
这两者都会引起整个系统内气压相应变化,可能造成防气阀的泄露。
Observe the pressure differential gauge. If there is a decrease in the indicated value, the No. 1 check valve is reported as leaking.
观察压差表。如果指示值有下降，则1号止回阀就报告为泄漏。
