What Are The Characteristics Of Pull Off Valves

1. The spring cylinder balance system of the pull-off valve, which has undergone precise calculation, ensures that the crane tube (loading and unloading arm) meets the requirements of random balance, and the alignment operation is light and convenient. Crane pipe is a type of pipe that can be retracted and moved, and is often used for liquid loading and unloading in petroleum and chemical terminals. The medium inside the pipe is such as oil and water. It is divided into various types and has advantages such as high safety and flexibility compared to old-fashioned hoses.
2. Made of PTFE reinforced PTFE material, it has excellent wear resistance, and the sealing surface has been polished, resulting in good sealing performance and long service life.
3. The pull off valve has a very reliable shut-off action, which is very suitable for cutting, adjusting, and throttling the medium. The unloading crane tube is suitable for loading and unloading various types of fuel oil, lubricating oil, edible oil, crude oil, heavy oil, and other oils. It can also be used for sending and receiving various liquid raw materials in chemical and other industries.
4. The crane tube (loading arm) used for loading and unloading flammable and explosive media is equipped with high-quality and reliable electrostatic earthing system, and the electrostatic resistance is less than 2 ohms.
2、 How to maintain the pull off valve
1. Prevent insufficient lubrication of the pull off valve, depletion of lubricating oil, and rupture.
2. Internal foreign objects, due to the detachment of internal parts during the working process, result in operations between internal parts.
3. Poor surface cracking.
4. Intermittent effects are significant, and some support equipment may work intermittently due to transient effects.
5. Unpredictability, or impact of objects beyond the mechanical working range, resulting in fracture.
6. During overload operation, the power is the rated value. If the actual torque used exceeds the rated torque used, overload may cause rupture due to the overload operation of the pull off valve.
7. The pull off valve is used to protect the loading arm of the receiving station and prevent the risk of truck or rail car separation. Pull off valves have been recognized and used by major global operators. Pull off valves are industry standard products, and cables that meet the standards can be anti-static and installed as standard.
8. The advantages of the pull off valve are lightweight, short, compact structure, designed specifically for the special balance requirements of the loading arm, lightweight material, suitable for situations with limited available space, overall lightweight, easy to handle, and also improving operational efficiency.
