For air tightness and air opening performance inspection of submarine valves used in fuel tank trucks and tankers.
Submarine Valve Inspection Equipment is specially designed for quality inspection and functional testing of submarine valves used in fuel tank trucks and tankers. It ensures the sealing performance and opening reliability of submarine valves during loading and unloading operations, helping to guarantee vehicle safety and operational stability.
The submarine valve is composed of a valve body, valve core, spring, piston, cylinder opening mechanism and sealing components. It is installed at the bottom of fuel tanks on tank trucks and tankers to control oil loading and unloading.
During operation, compressed air pushes the piston to compress the spring, driving the valve core away from the sealing surface to open the valve and allow fuel discharge. As a critical safety component of tank vehicles, the performance and reliability of the submarine valve directly affect vehicle quality.
This inspection equipment provides accurate and repeatable testing to verify valve airtightness and opening performance.
