CQA tank truck ball valve
Other Products
I. Introduction:
The tank truck ball valve is installed downstream of the emergency shut-off valve via flange connection. Its outlet is matched with a quick connector of the same specification, used for switching on and off during loading, unloading, and pressure relief of the medium. It is equipped with a vent valve, suitable for liquefied gas tank trucks and liquid ammonia tank trucks. It adopts a floating sphere for opening and closing, with fast operation speed. Main structural features: The sphere rotates around the axis of the valve stem to achieve opening and closing; when the valve stem rotates clockwise, the sphere rotates 90 degrees to cut off the channel; when rotating counterclockwise, the sphere rotates 90 degrees in the reverse direction to open the channel; the constantly contacting sphere surface and sealing ring effectively scrape off attachments on the sphere surface; when fully open, it forms a full-channel straight-through structure, minimizing fluid resistance; it adopts a floating sphere and fixed elastic seat sealing structure, ensuring excellent sealing performance; it features a fine-adjustable valve cover structure, extending the service life of the valve and ensuring safe and reliable use; a vent valve is set at the outlet, enabling safe loading and unloading of the loading and unloading pipe assembly.
