What is the purpose of a gate valve?

Soft seal gate valve is a valve widely used in water supply and drainage, industry, construction and other fields, mainly used to control the flow and on-off of the medium. The following points need to be paid attention to in its use and maintenance:

How to use？

Operation mode: The operation of the soft seal gate valve should be closed clockwise and opened counterclockwise. In the case of pipeline pressure, the larger opening and closing torque should be 240N-m, the opening and closing speed should not be too fast, and the large-diameter valve should be 1 within 200-600 rpm.

Operating mechanism: If the soft seal gate valve is laid deeply, when the operating mechanism and the indication disc are 1.5m away from the ground, they should be equipped with an extension rod device, and they should be fixed firmly to facilitate direct operation from the ground 1.

Opening and closing operating end: The opening and closing operating end of the soft seal gate valve should be square tenon, standardized in specification, and facing the road surface, which is convenient for direct operation from the road surface 1.

Maintenance

Regular inspection: Regularly check the connection between the electric actuator and the valve to ensure that the connection is firm; Check the power and control signal cables to make sure they are well connected and not loose or damaged2.

Cleaning and maintenance: Regularly clean the debris and dirt inside the valve to keep the valve clean and unobstructed 2.

Lubrication Maintenance: Lubricate and maintain electric actuators regularly to ensure their proper operation2.

Seal performance inspection: Regularly check the sealing performance of the valve, if there is leakage, the seal 2 should be replaced in time.

Common problems and solutions

Reduced sealing performance: If the valve is found to be leaking, the seal should be replaced in time.

Inflexible operation: Lubricate and maintain the electric actuator regularly to ensure its proper operation.

Loose connection: Regularly check the connection between the electric actuator and the valve to ensure that the connection is secure.

Through the above methods and precautions, the service life of the soft seal gate valve can be effectively prolonged, and its normal operation and safe use can be ensured.
