PBQ940-10C eccentric hemispherical valve for chemical wastewater transportation

working principle

Eccentric hemispherical valve mainly consists of valve body, valve cover, valve ball, valve seatcontrolComposed of components such as rods and transmission devices. Valve balls are usually made of metal material, and the surface can be coated with different materials to enhance sealing performance. The valve seat adopts a floating design to ensure the connection with the valve ballaccuratecoordination. When the valve is closed, the valve ball and seatallContact, form a seal, prevent fluid flow; In the open state, the valve ball rotatestoSpecific angles allow fluid to pass smoothly.

Adopting an eccentric structure and elastic valve seat design, it can achieve good sealing and minimal leakage when closed. The sealing between the valve seat and the valve body adopts a hard sealing structure, which is suitable for high temperature and high pressure working conditions. Two point hard seals are selected between the valve seat and the valve body, as well as between the valve seat and the hemisphere, further enhancing the sealing effect and effectively preventing sewage leakage. The core and valve seat are usually made of wear-resistant and corrosion-resistant materials, such as hard alloy, stainless steel, etc. The valve seat and hemisphere are also treated with special hardening technology, which can withstand the erosion and corrosion of various impurities in sewage, adapt to harsh sewage transportation conditions, and extend the service life of the valve.

Combined with electric actuators, precise adjustment of flow can be achieved, meeting the high-precision requirements for flow control in the process of chemical wastewater transportation, and suitable for the transportation of wastewater in the chemical industry. Chemical wastewater usually contains various corrosive media, impurities, etc. The PBQ940-10C eccentric hemispherical valve, with its good sealing, wear resistance, corrosion resistance, and precise flow regulation ability, can reliably control the transportation of wastewater and ensure the stable operation of wastewater discharge and treatment systems in the chemical production process.
