1. Inspection and verification.
Before installing a butterfly valve, the valve must first be inspected and checked. Check whether the specifications and models of the valve meet the design requirements, and check whether the material, pressure level and other parameters of the valve match the pipeline system. At the same time, it is necessary to check whether the appearance of the valve is damaged or defective, and if any abnormalities are found, they should be treated or replaced in time.
Second, the installation environment.
The installation environment of the butterfly valve should be dry and well-ventilated, and the temperature and humidity should meet the requirements of the relevant standards. Avoid installation in environments with corrosive gases or large amounts of dust to avoid damage to the valve. In addition, it is necessary to keep it clean during installation to avoid debris entering the inside of the valve cavity.
3. Installation direction.
The installation direction of the butterfly valve should be carried out in accordance with the design requirements, and in general, the arrow direction of the butterfly valve should be consistent with the fluid flow direction. In special cases, the appropriate installation method should be selected, such as horizontal installation or vertical installation. At the same time, during the installation process, it is necessary to ensure that the bracket and support seat of the valve are stable and reliable, so as to prevent the valve from shaking or shifting during use.
Fourth, operation and commissioning.
When installing the butterfly valve, it is necessary to operate and debug it correctly. According to the working principle and system requirements of the valve, the opening of the butterfly valve is reasonably adjusted to ensure its normal operation. At the same time, during the commissioning process, it is necessary to observe whether the sealing performance and fluid flow of the butterfly valve meet the requirements, and if there is a problem, it should be adjusted or replaced in time.
5. Maintenance and maintenance.
Butterfly valves require regular maintenance and maintenance during use. Regularly check whether the sealing performance and packing of the valve are in good condition, and replace or replenish it in time if leakage is found. At the same time, the residue and dirt inside the valve should be cleaned regularly to keep the valve clean and in good working condition. It is also necessary to pay attention to avoid overpressure use during use, so as not to cause damage to the valve.
6. Safety precautions.
When installing and using butterfly valves, pay attention to safety. Personal protective equipment such as protective gloves and goggles should be worn during operation to prevent valve leakage or improper operation from causing harm to the human body. At the same time, in the process of disassembly and maintenance, relevant safety operation procedures should be followed to ensure the safety of personnel and the normal operation of equipment.
