The device used to control the flow of fluid in the pipeline is called a valve. Its main function is: On-off - cut off or connect the fluid flow in the pipeline； Regulating - regulating the flow rate and flow rate of the fluid in [...]
Valve castings The valve is used on the fluid pipeline. It withstands itself the erosion and corrosion of various temperatures and pressure media. There are even small defects in the casting that can also leak, causing loss and waste of media. When transporting toxic and [...]
Performance of fully welded ball valves 1. No maintenance, adjustment and lubrication required, easy to install, long-term reliable operation at low operating cost. The surface adopts plastic spraying treatment technology, with beautiful luster, which is already at the leading level in China. There will be [...]
Summary Pipeline transportation has become one of the main methods of contemporary material transportation. The use of long-distance pipelines to transport oil and gas resources has become the most important mean of energy transportation in the world today. The major oil and gas producing and [...]
Check the ball valve is in the fully open position After completing the grease injection operation, firstly, check whether the hole path of the valve ball is flush with the plane of the inner cavity of the valve seat. If there is any difference, the [...]
Technical characteristics of fully welded ball valve: 1. The valve body structure is integrally welded without external leakage. 2. The valve seat is composed of PTFE sealing ring and spring, which has strong adaptability to pressure and temperature changes, and will not cause any leakage [...]
The valve body design of the fully welded ball valve has a cylindrical structure and a spherical structure. The cylindrical structure is a double-welded seam. The welding process has large heat input, complex residual stress, and large axial and radial deformation. The spherical structure is [...]
The flow and velocity of the valve mainly depend on the diameter of the valve, and also the resistance of the valve structure to the medium. At the same time, it has a certain internal relationship with the pressure, temperature and medium concentration of the [...]
Industrial valves are used to open and close the pipeline, control the flow direction, regulate and control the parameters of the conveying medium (temperature, pressure and flow) of the pipeline accessories. 1. Strength performance The strength of the valve is the ability of the valve [...]
1. Valve It is used to control the flow of medium in the pipeline, and it is the general of mechanical products with movable mechanism. 2. Gate valve, slide valve The on-off part (shutter) is driven by the valve stem and moves up and down [...]
