316 eccentric hemispherical valve for sewage treatment plant

Eccentric hemispherical valve is a relatively new type of ball valve, which has some structural features of its ownexcellentSex, such as frictionless switches, seals that are not easily worn, and low opening and closing torque. This can reduce the specifications of the accompanying actuator. Equipped with multiple rotationsElectric actuatorIt can achieve regulation and tight cutting of the medium. Widely applicable to working conditions that require strict cut-off in petroleum, chemical, urban water supply and drainage, etc.

Overview of Eccentric Hemisphere Valve

Eccentric hemispherical valve is a type of valve withspecialThe high-performance valves designed are widely used in the industrial field, especially in the need foraccurateIn situations where fluid flow direction and flow rate are controlled. Its design feature is that the center of the valve ball does not coincide with the center of the valve body, but deviates by a certain distance. This design reduces the friction between the valve ball and the valve seat, improves the opening and closing efficiency and use of the valvetimeNext, we will delve into the detailed information of eccentric hemispherical valves from multiple perspectives.

Advantages of eccentric hemispherical valve

Eccentric hemispherical valves have multiple advantages, including excellent sealing performance, accurate fluid control capability, strong corrosion resistance, simple structure, and reliable operation. These advantages make it perform well in fluid control under harsh working conditions such as high temperature, high pressure, strong corrosion, high viscosity, and solid particles.

The application of eccentric hemispherical valves is extremely extensive, covering multiple industries such as petroleum, chemical, power, metallurgy, shipbuilding, etc. In these industries, eccentric hemispherical valves are mainly used to control, cut off, and regulate fluids, such as oil transportation, chemical raw material processing, hot water or steam control in power systems, etc.

It relies on rotating the valve chain to make the valve unobstructed or blocked. Ball valve switch is lightweight, small in size, can be made into large diameters, reliable in sealing, and structurally sound Simple and easy to maintain, the sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and has been widely used in various industries.

The products are divided into six series according to their uses: universal valves, pipeline valves, slurry valves, gas valves, petrochemical valves, and coal powder injection valves. There are three transmission modes: manual, pneumatic, and electric, with eight pressure levels（PN0.25-6.4Mpa) is a hemispherical valve product with hundreds of specifications (40-1000). In industries such as petroleum, chemical, metallurgical, power, and gas, it is an upgraded product of gate valves, globe valves, Y-shaped valves, and ball valves. At present, it has been used in coal powder injection in the steel industry, slurry, mother liquor and alumina powder transportation in the alumina industry, hydraulic (or dry) ash removal in the power industry, petrochemical industry, gas industry and other occasions.
