产品描述
  
       B43H石英玻璃管液位计是一次仪表设备,安装在锅炉等容器上,直接观测水位,是监视锅炉水位、保证锅炉安全运行的可靠仪表。  
       石英玻璃管液位计由上阀(气阀)、下阀(水阀)、表体、排污阀、平衡管等组成。上阀和下阀是一快速组合阀,除手动快速全开与全闭外,由于阀体内部有保险阀座与保险钢球,当石英玻璃管突然爆裂时,保险钢球在高压汽水的冲击下高速顶向保险阀座,自动关闭表体的上下通道,直至手动关闭快速阀为止。保险钢球的复位,通过平衡管取得压力平衡,靠保险钢球的自重而取得,因此不会出现假水位等不良现象。

The B43H quartz glass tube liquid level gauge is a primary instrument equipment installed on boilers and other containers, directly observing the water level. It is a reliable instrument for monitoring boiler water level and ensuring safe operation of the boiler.

The quartz glass tube level gauge is composed of an upper valve (gas valve), a lower valve (water valve), a gauge body, a drain valve, a balance tube, etc. The upper and lower valves are a quick combination valve. In addition to manual quick full open and full close, due to the safety valve seat and safety steel ball inside the valve body, when the quartz glass tube suddenly bursts, the safety steel ball will push towards the safety valve seat at high speed under the impact of high-pressure steam, automatically closing the upper and lower channels of the meter body until the quick valve is manually closed. The reset of the safety steel ball is achieved through the balance pipe to achieve pressure balance, relying on the self weight of the safety steel ball, so there will be no adverse phenomena such as false water level.
