Installation process of threaded ball valve

The installation process of threaded ball valves requires following certain steps to ensure their correct installation and good operation. The following is a detailed introduction to the installation process of threaded ball valves: 1、 Preparation before installation 1. Check the pipeline: Ensure that the pipelines before and after the ball valve are ready, and that the pipelines are coaxial, with the two flange sealing surfaces kept parallel. The pipeline must be able to withstand the weight of the ball valve. If the pipeline cannot support it, please install appropriate support structures on the pipeline. 2. Cleaning pipelines: Use compressed air or appropriate cleaning tools to blow clean the pipelines before and after the ball valve, removing oil stains, welding slag, and other impurities. This helps to reduce wear and leakage of the valve during use.

Why is it necessary to specify a sealing device for gate valves and globe valves

Gate valves and globe valves are required to have upper sealing devices, mainly based on the following considerations: 1、 Prevent medium leakage and protect the filling material Prevent medium leakage: When the gate valve and globe valve are closed, the valve stem is in a stationary position. If there is no upper sealing device, the medium may penetrate upwards along the gap between the valve stem and the valve body, causing the medium to leak out. The upper sealing device can effectively prevent medium leakage, ensuring the working performance and safety of the valve. • Packing protection: The packing box is usually made of flexible materials such as asbestos, polytetrafluoroethylene, etc
