Overview of Low Temperature LCB Flat Gate Valve

Low temperature LCB flat gate valve is a buried gate valve specially designed for natural gas and petroleum media. It is mainly used on natural gas pipelines and oil pipelines for buried conditions, especially in countries and regions with low temperature climates where corresponding materials for low temperature are required. The low-temperature flat gate valve has additional connections and extensions for the drain valve, exhaust valve, and grease injection valve to the operating position, making it convenient for sunlight maintenance. In addition, our company has made special improvements to the structure of the packing part of the flat gate valve, achieving a true triple sealing effect. Gas flat gate valves have the characteristics of simple structure, reliable sealing, low switching torque, and long service life. The exhaust valve can be opened in the pipeline to release gas for maintenance and repair, ensuring safety.

Structural characteristics of low-temperature LCB flat gate valve

1. The valve seat of the low-temperature LCB flat gate valve adopts a low-temperature special O-ring seal and a floating valve seat structure with pre tension force, which enables bidirectional sealing of the inlet and outlet of the flat gate valve. The opening and closing torque of this structure is only half of that of ordinary valves, which can achieve easy opening and closing of the valve.

2. When the low-temperature LCB flat gate valve is fully opened, the channel is smooth and straight, the flow resistance coefficient is extremely small, there is no pressure loss, and it can clean the pipeline with a rough ball.

3. The low-temperature LCB flat gate valve adopts a packing structure with self sealing ability, which does not require frequent adjustment. It is extremely lightweight to open and close, and has reliable sealing performance. The packing box is equipped with an auxiliary sealing high-quality injection structure, and the sealing performance is absolutely reliable. In addition to PTFE packing, a triple sealing structure with 0-ring sealing sleeve is also added, which truly achieves zero leakage and solves the problem of easy leakage at the packing of general valves.

4. When the low-temperature LCB flat gate valve is closed, it can automatically release the high pressure inside the chamber, ensuring safe use.

5. Low temperature LCB flat gate valve has a fully enclosed structure, good protection performance, and can adapt to all-weather requirements.

Precautions for using low-temperature LCB flat gate valve:

1. Say the important thing three times: don't push yourself to the brink of death! Don't push yourself to the brink of death! Don't push yourself to the brink of death!

2. When opening or closing in place, the valve stem handle or handwheel should be rotated 1/2 turn. To ensure that the gate is in a floating state and maintain good sealing performance.
