DH7cs41 type hydraulic controlled check valve is my company for many years in the extensive collection, research, on the basis of the check valve performance at home and abroad, combining to eliminate water hammer, aim to protect the safety of water pump and pipeline system and developed an intelligent patent product and is suitable for large and medium-sized water pump outlet and at the inlet of the turbine, pump valve or valve machine linkage, the main features are:
1, original lifting heavy hammer type structure form, and not emptying storage structure, take up the space is little, the use of safe and reliable.
2, original mechanical joint electromagnetic lock, effectively prevent drop phenomenon.
The working principle of the valve is: open the valve, the use of hydraulic station and lifting oil cylinder force, through the lift arm, drive pin, valve shaft parts such as driven disc to rotate 90 degrees. When the valve is fully open, the mechanical lever, swinging rod and of the electromagnet electromagnetic force joint locking, keep long-term valve in the fully open position, to ensure absolute not to drop hammer. Close the valve by fast, slow clearance of two programs, the whole process with one.
The valve can not only on-site operation, also can remote control, running state can show that run results have signal, the product performance in the domestic leading level.
