Ball valves include: floating ball valve, fixed ball valve, orbital ball valve, V-shaped ball valve, three-way ball valve, stainless steel ball valve, cast steel ball valve, forged steel ball valve, ash discharge ball valve, anti-sulfurization ball valve, pneumatic ball valve, electric ball valve, card sleeve ball valve , Welded ball valves, etc.
According to the classification of shell/body material, ball valves can be divided into:
Metal material valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium alloy valves, Monel valves, copper alloy valves.
Car doors, aluminum alloy valves, lead alloy valves, etc.
Valves lined with metal valve bodies: for example: rubber-lined valves, fluorine-lined valves, lead-lined valves, rubber-lined valves, porcelain-lined valves, etc.
Non-metallic valves: such as ceramic valves, glass valves, plastic valves, etc.
There are many ball valve manufacturers in my country, and the connection sizes are also not uniform. It is mainly divided into the following categories:
The ball valve ball is floating. Under the action of the medium pressure, the pilot solenoid valve manufacturer's ball can produce a certain displacement, and it is close to the sealing surface of the outlet end to ensure the seal of the outlet end.
Ball valve structure:
The sealing performance is good, but all the load of the sphere bearing the working medium is transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material of the two-position five-way solenoid valve can withstand the load of the sphere medium. When subjected to high pressure impact, the sphere may be displaced. This structure is generally used for medium and low pressure ball valves.
The ball of the ball valve is fixed and does not move after being compressed. The fixed ball valve is equipped with a floating valve seat. When subjected to medium pressure, the valve seat will move, so that the sealing ring is fastened to the sphere to ensure sealing. Generally, the bearings are installed on the upper and lower shafts of the ball, and the torque distance is small, which is suitable for high pressure and large diameter valves.
