Ball valves have evolved from plug valves. It has the same 90 degree rotation lifting action, but the difference is that the plug body is a sphere with a circular through-hole or channel passing through its axis. The ratio between the sphere and the channel should be such that when the sphere rotates 90 degrees, it should all appear spherical at the inlet and outlet, thereby cutting off the flow. ...

The process of shell and sealing tests for turbine fixed ball valves in some artificial environments is as follows. The dual blocking and discharging function of the turbine fixed ball valve: a spring pre tightened floating valve seat is used to fix the turbine ball valve. When the valve is in two different states, fully open and fully closed, the fluid is blocked by the upstream and downstream va...

The safety valve plays a safety protection role in the system. When the system pressure exceeds the specified value, the safety valve opens and releases a portion of the gas in the system into the atmosphere, ensuring that the system pressure does not exceed the allowable value, thereby ensuring that accidents do not occur due to excessive pressure. Safety valve, also known as relief valve. The di...

Working principle of pressure reducing valve 1) From the perspective of fluid mechanics, a pressure reducing valve is a throttling element that can change local resistance, that is, by changing the throttling area, the flow rate and fluid kinetic energy change, causing different pressure losses, and thus achieving the purpose of pressure reduction. It relies on the adjustment of the control and ad...

Check valves may be the most easily misunderstood valve in history. If you mention check valves to most factory personnel, the typical reaction is "they don't work.". In fact, these personnel are likely to have removed internal components or refurbished the system to avoid using check valves. In other words, these valves may be the least popular valves currently in use. This article will explore t...

Ball valve and plug valve belong to the same type of valve, with only its closing part being a sphere. The sphere rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. Ball valve is a new type of valve widely used in recent years, which has the following advantage...

Ball valve is a common type of valve, and its design characteristics make it widely used in various industrial applications. Ball valves are favored for their simplicity, reliability, and ease of operation, playing an important role in fluid control. The main components of a ball valve include a sphere with a diameter and inlet and outlet pipes located on both sides of the sphere. Spheres are usua...

At present, the commonly used hardening processes for the surface of metal hard sealed ball valves mainly include the following: (1) Surface welding (or spray welding) of hard alloy on the sphere can achieve a hardness of over 40HRC. The process of surface welding of hard alloy on the sphere is complex, with low production efficiency, and large area welding can easily cause deformation of the part...
