AI Technical Summary
During the hoisting and transportation of existing chiller units, the oil unloading valve is easily damaged by collision, posing a risk of oil leakage and affecting product quality and safety.
A removable protective component is installed on the outside of the unloading valve and fixed with existing fasteners. The protective component is connected to the cover plate and has an operating port and a clearance part to facilitate pipeline connection and prevent collision with the unloading valve.
The protection effect of the unloading valve has been improved, avoiding collisions during hoisting and transportation, and enhancing safety and ease of operation.
