AI Technical Summary
Dust tends to accumulate on the solenoid base of proportional multi-way valves used in mines, leading to poor heat dissipation and requiring frequent cleaning to maintain normal operation.
Design an explosion-proof electro-hydraulic proportional multi-way valve, which uses a shield to cover the electromagnetic base, and sets heat dissipation space, through groove and channel between the shield and the electromagnetic base. The elastic sheet conducts heat, and the shield is rotatably connected to the mounting plate for easy maintenance and cleaning.
It effectively blocks dust, prolongs the dust layer formation time, improves heat dissipation efficiency, simplifies the maintenance process, reduces cleaning difficulty, and enhances the applicability and versatility of the equipment.
