What are the main factors affecting the sealing performance of butterfly valves?
Sealing is to prevent leakage, and the principle of valve sealing is also studied from leakage prevention. There are many factors that affect the sealing performance of butterfly valves, mainly including the following: 1. Sealing structure Under the change of temperature or sealing force, the str...Read more -
Why do stainless steel valves also rust?
People usually think that the valve of stainless steel and will not rust. If it does, it may be a problem with the steel. This is a one-sided misconception about the lack of understanding of stainless steel, which can also rust under certain conditions. Stainless steel has the ability to resist a...Read more -
Application of butterfly valve and gate valve under different working conditions
Gate valve and butterfly valve both play the role of switching and regulating flow in pipeline use. Of course, there is still a method in the selection process of butterfly valve and gate valve. In order to reduce the depth of soil covering of the pipeline in the water supply network, generally l...Read more -
What are the differences and functions of single eccentric, double eccentric and triple eccentric butterfly valve
Single eccentric butterfly valve In order to solve the extrusion problem between the disc and the valve seat of the concentric butterfly valve, the single eccentric butterfly valve is produced. Disperse and reduce the excessive extrusion of the upper and lower ends of the butterfly plate and the ...Read more -
Check valve working principle, classification and installation precautions
How check valve works The check valve is used in the pipeline system, and its main function is to prevent the backflow of the medium, the reverse rotation of the pump and its driving motor, and the discharge of the medium in the container. Check valves may also be used on lines supplying auxiliar...Read more -
Y-strainer installation method and instruction manual
1.The filter principle Y-strainer is an indispensable filter device in the pipeline system for conveying fluid medium. Y-strainers are usually installed at the inlet of pressure reducing valve, pressure relief valve, stop valve (such as the water inlet end of indoor heating pipeline) or other equ...Read more -
Common fault analysis and structural improvement of Dual plate wafer check valve
1. In practical engineering applications, the damage of Dual plate wafer check valves is caused by many reasons. (1) Under the impact force of the medium, the contact area between the connecting part and the positioning rod is too small, resulting in stress concentration per unit area, and the Du...Read more -
The basis for choosing the butterfly valve electric actuator
A. Operating torque The operating torque is the most important parameter for selecting the butterfly valve electric actuator. The output torque of the electric actuator should be 1.2~1.5 times the maximum operating torque of the butterfly valve. B. Operating thrust There are two main struc...Read more -
What are the ways of connecting the butterfly valve to the pipeline?
Whether the selection of the connection method between the butterfly valve and the pipeline or equipment is correct or not will directly affect the probability of running, dripping, dripping and leaking of the pipeline valve. Common valve connection methods include: flange connection, wafer conne...Read more -
Introduction of valve sealing materials—TWS Valve
Valve sealing material is an important part of valve sealing. What are the valve sealing materials? We know that valve sealing ring materials are divided into two categories: metal and non-metal. The following is a brief introduction to the use conditions of various sealing materials, as well as ...Read more -
Installation of common valves—TWS Valve
A.Gate valve installation Gate valve, also known as gate valve, is a valve that uses a gate to control the opening and closing, and adjusts the pipeline flow and opens and closes the pipeline by changing the cross section. Gate valves are mostly used for pipelines that fully open or fully close t...Read more -
The difference between OS&Y gate valve and NRS gate valve
1.The stem of the OS&Y gate valve is exposed, while the stem of the NRS gate valve is in the valve body. 2.The OS&Y gate valve is driven by the thread transmission between the valve stem and the steering wheel, thereby driving the gate to rise and fall. The NRS gate valve drives th...Read more
