AI Technical Summary
The existing sealing device of the three-way valve used in mines is unable to withstand impact, which leads to damage to the sealing structure, leakage, and affects equipment operation and safety.
An impact-resistant sealing device including a buffer mechanism was designed. By combining a sealing slide plate and a buffer spring, the impact force is reduced, ensuring the stability of the valve core sealing structure. The valve body is opened and closed by a screw and a rotating handle.
It effectively prevents the valve core sealing structure from being damaged by impact, avoids leakage, ensures the normal operation and safety of equipment, and improves the safety of mine workers.
