UB series glass plate level gauge

The UB-1 and UB-2 series glass plate level gauges can be used to directly indicate the liquid level height in sealed containers, and have a simple structure
Single, intuitive, reliable, and durable, but the medium in the container must be non corrosive to steel, steel paper, and graphite pressure rings.
□ Structural principle
The instrument is equipped with M27 × 1.5 or ZG3/4 "threaded joints on both the upper and lower valves, which are connected to the container through flanges to form a connector. The height of the liquid level in the container can be directly read through the glass plate.
The instrument is equipped with steel balls inside both the upper and lower valves. When the glass plate is damaged due to an accident, the steel balls will block the channel under the pressure inside the container, so that the container will automatically seal and prevent the liquid inside the container from continuing to flow out.
There are blocking hole screws at the valve end of the instrument, which can be used for sampling or for releasing residual liquid in the instrument during maintenance.
□ Characteristics
The reading is clear, intuitive, and reliable.
● Simple structure and easy maintenance.
Durable and long-lasting.

□ Installation and usage instructions
To ensure automatic sealing, the pressure of the medium inside the container should be greater than 0.2 MPa. When opening the upper and lower valves, the valve stem should retract at least 4 revolutions to prevent the steel ball from touching the top of the valve stem when sealing the door.
