Check valve is a valve in which the opening and closing member is a circular valve flap and acts on its own weight and medium pressure to block the reverse flow of the medium. It is an automatic valve, also known as a check valve, non return valve or isolation valve.
The two eccentricities of the double offset butterfly valve refer to the eccentricity of the rotating center line of the disc and the eccentricity of the sealing line and the eccentricity of the center line of rotation of the disc and the center line of the channel.
A butterfly valve is a valve in which a closing part is a disc that rotates around the valve shaft to open and close, and is mainly used for cutting and throttling on the pipeline.
Compared with other valves, the butterfly valve has a simpler structure. It is smaller in size, lighter in weight, and has fewer components. It relies on several key components to form a butterfly valve, but it has achieved better use.
Butterfly valve is a valve that uses a circular disc as a shutter to open, close, and adjust the fluid passage as the stem rotates. The butterfly valve's disc is mounted in the diameter direction of the pipe.
Butterfly valves are used in a wide range of applications. The variety and quantity used continue to expand, and the development of high temperature, high pressure, large diameter, high sealing, long life, excellent regulation characteristics, and multi-valve. Its reliability and other performance.
The double offset butterfly valve is further improved on the basis of a single eccentric butterfly valve. The structural feature is that the stem axis is eccentric from the center of the disc and from the center of the body.
The ball of the floating ball valve is floating without a mounted shaft. Under the action of the medium pressure, the ball can generate a certain displacement and press on the sealing ring at the outlet end to ensure the sealing of the outlet end, which is a single-sided forced seal.
A ball valve with a Trunnion mounted shaft, called a Trunnion mounted ball valve. Trunnion mounted ball valves are mainly used for high pressure and large diameter. Depending on the mounting of the seat seal, the trunnion mounted ball valve can be constructed in two configurations.
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
