How to install and anti-corrosion the cylinder valve?

The installation of the cylinder valve takes approximately seven steps to complete:
1. Clean the valve; perform a thorough cleaning when the valve is fully opened.
2. An overall inspection is required before installation, and installation can only be carried out after reaching the standard.
3. Since impurities in the pipeline will damage the valve, the pipeline should be flushed before the pipeline is connected.
4. During installation, please do not use the main mechanism part of the cylinder valve as the lifting point to avoid damage to important mechanisms and accessories. .
5. The ball valve of the valve should be installed in the horizontal direction (vertical direction) of the pipeline as the most reasonable installation method.
6. There should be no stress (drooping) phenomenon in the pipeline near the installation point. Only use the bracket of the pipeline to solve the deviation of the pipeline.
7. After the cylinder valve is connected to the pipeline, the bolts should be locked.

The corrosion problem of the cylinder valve is usually understood as the damage of the metal material of the cylinder valve V-type regulating ball valve under the action of external factors. Since the corrosion phenomenon occurs under the action of the valve body material and the surrounding environment, try to separate the cylinder valve body material from the environment. The use of non-metallic composite materials on the cylinder valve is the key to preventing corrosion of the valve body. The valve body of the cylinder valve occupies more than half of the weight of the valve. Since the valve body and the medium are often in contact, the selection and use of the valve starts with the material of the cylinder valve body.

There are two reasons for valve body corrosion: one, chemical corrosion; two, electrochemical corrosion.

The corrosion rate of the cylinder valve body depends on the temperature and pressure of the medium, as well as the chemical properties and the corrosion resistance of the valve body material. The corrosion rate can be divided into six grades: poor corrosion resistance, complete corrosion resistance, corrosion resistance, no corrosion resistance, extremely corrosion resistance, and still corrosion resistance.

The anti-corrosion performance of the cylinder valve mainly depends on the selection of the correct material to make the valve. Although such materials are abundant, it is not easy to choose suitable materials, and the problem of valve body corrosion is very complicated. The choice of valve body material should not only consider the problem of corrosion, but also the ability to withstand pressure and temperature.

Care must be taken when choosing a valve, and attention must be paid to the operation of each link during installation.
