How to correctly select and use D71XAL China anti-condensation butterfly valve

D71XAL China anti condensation butterfly valve is a valve specially used to prevent condensation phenomenon, widely used in air conditioning, industrial water treatment and other fields. However, due to the numerous brands and different models of D71XAL anti-condensation butterfly valves on the market, users are often confused when purchasing. This article will introduce how to correctly select and use D71XAL China anti-condensation butterfly valve from a professional perspective.

First, the correct choice of D71XAL China anti-condensation butterfly valve

1. Determine the valve type: According to the actual engineering needs, choose the appropriate D71XAL anti-dew butterfly valve type, such as center line type, flange type, etc. Different types of valves are suitable for different working conditions and pipe connections.

2. Determine the valve material: D71XAL China anti-condensation butterfly valve material is mainly cast steel, stainless steel, aluminum alloy and so on. Valves of different materials have different corrosion resistance and service life. When selecting, the appropriate material should be selected according to the nature and temperature of the medium.

3. Determine the pressure level of the valve: D71XAL The pressure level of China’s anti-condensation butterfly valve is usually PN0.1-2.5Mpa. In the selection, the pressure level of the valve should be determined according to the actual engineering pressure to ensure the safe operation of the valve.

4. Determine the valve diameter: D71XAL China anti-condensation butterfly valve nominal diameter range is DN50-300mm. In the selection, the diameter of the valve should be determined according to the actual project pipe size to ensure the installation and use of the valve.

Second, the correct use of D71XAL China anti-condensation butterfly valve

1. Check before installation: Before installing D71XAL China anti-condensation butterfly valve, check the appearance of the valve first to ensure that the valve is not damaged, rust and other phenomena. At the same time, it should also check whether the valve model, specification, pressure grade and other parameters meet the design requirements.

2. Installation precautions: When installing D71XAL anti-condensation butterfly valve, the following points should be paid attention to:

(1) The installation position should be as close as possible to the end of the pipeline to facilitate the discharge of condensate;

(2) When installing, ensure that the valve is perpendicular to the pipeline axis to ensure the normal operation of the valve;

(3) The clamping connection mode should be used during installation to facilitate the disassembly and maintenance of the valve;

(4) Special tools should be used during installation to avoid damage to the valve.

3. Use precautions: When using D71XAL anti-condensation butterfly valve, the following points should be paid attention to:

(1) During use, the valve should be checked and maintained regularly to ensure the normal operation of the valve;

(2) During use, the valve should be avoided from severe impact or excessive twisting to avoid damage to the valve;

(3) During use, the opening and flow of the valve should be controlled according to the design requirements to ensure the normal operation of the system;

(4) In the process of use, if the valve is found to have abnormal phenomena (such as leakage, stuck, etc.), it should be handled in time.
