In recent years, with the continuous improvement of China's comprehensive national strength, the development of China's marine industry has also achieved rapid progress. In this context, the shipbuilding industry has drawn much attention.
The industrial valves are in the fluid system. The device used to control the direction, pressure, and flow of the fluid is the device that allows the flow and stops of the medium (liquid, gas, powder) in the pipe and equipment and can control its flow. The valve is the fluid delivery system.
In the use of electric industrial butterfly valve, the use environment is often damaged due to leakage problems, so preventing leakage is an important problem that needs to be solved by electric butterfly valves. Introduce several methods that can effectively solve the leakage of electric butterfly valves.
Lift check valve: A valve that check valve slides along the center line of the valve body. Pipeline check valve is a new type of valve. It is small in size, light in weight and good in process ability.
The wafer check valve is applied to various lines of Class150~Class2500 and PN20～PN420 to prevent the medium in the pipeline from flowing back. Different materials are used, and the check valve can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
Valve is important equipment in many process control systems, which has a significant impact on the reliability of the control system, the accuracy of the adjustment and the safety of the operation.
Plug valves are best suited for use as a globe and closing medium as well as for shunting, but can sometimes be used for throttling depending on the nature of the application and the erosion resistance of the sealing surface. It is also commonly used for media with suspended particles due to the wip
The needle valve is evolved from the globe valve, sometimes called the needle valve globe valve. The specific difference is that the disc of the needle valve is a sharp cone, which is inserted into the valve seat like a needle. The needle valve is a kind of valve that can be precisely adjusted. For
Compared with the gate valve, the globe valve has the advantages of simple structure, good sealing performance and convenient manufacturing and maintenance; The gate valve and the globe valve are full-open and fully-closed valves.
Compared with the gate valve, the globe valve has the advantages of simple structure, good sealing performance and convenient manufacturing and maintenance; the disadvantage is that the liquid resistance is large, and the opening and closing forces are large.
