What are the specific functions of the rotary valve on the guide rail lifting platform?

The application of slide rail lifting platform is convenient, easy to maintain, and affordable, and is widely used in second and third floor factories, especially in industrial production sites where excavation of foundation pits is not allowed. What are the functions of the rotary valve of the sliding rail lifting platform? The rotary valve of the lifting platform is a type of gate valve that quickly opens and closes (functions: shut-off, drainage, stabilizing tube, separation, etc.). The rotary valve can reduce the optimization route setting of the oil pipeline safety channel in a profitable manner.

The basic principle of the lifting platform rotary valve is that when the lifting platform is raised, the rotary valve will automatically open. If you want to close the plug valve, you must first rotate the joystick to rotate the plug valve to the 90 degree position until it is closed, and then rotate the transmission system handle to reduce the sealing performance of the plug valve.

Advantages of sliding rail lifting platform rotary valve:

Simplified the setting of lifting platform pipelines;

Secondly, the actual operation is simpler, and the gate valve can be opened and closed anytime and anywhere;

Thirdly, installing a rotary valve reduces the friction of hydraulic seals;

Fourthly, the structure is inseparable and lightweight, saving indoor space;

Fifth, it has improved the service life of the lifting platform pipeline and addressed the current situation of easy oil leakage. Maintenance and upkeep of hydraulic press

For mechanized construction companies, the excellent technical condition of engineering machinery and equipment is an immediate factor in whether the company can produce and manufacture everything normally. For engineering machinery equipment with hydraulic transmission systems, the normal operation of the hydraulic system is a key indicator of its excellent technical condition. Qualified hydraulic oil is the guarantee of reliable operation of hydraulic systems, and proper maintenance is the essence of reliable operation of hydraulic systems. Therefore, based on practical activities in work, I will briefly discuss the maintenance and upkeep of hydraulic systems in engineering machinery and equipment in general natural working environments.
