- Seat ring (Image Part A) Seat ring is one of the key components in the lug butterfly valve, located on the seat inside the valve body. Its main function is to provide sealing effect, so that the valve can realize fast switching when working, and effectively control the opening and closing status of the fluid channel. Seat ring is usually made of wear-resistant materials, such as high-density polytetrafluoroethylene (PTFE), to ensure its durability and sealing.
- Valve Plate (Image Part B) The valve plate is the core component in the construction diagram of the lug butterfly valve, responsible for controlling the opening and closing of the fluid passage. This component is made of a disk-shaped metal plate, usually made of stainless steel and other corrosion-resistant materials. The valve plate realizes the opening and closing action of the valve by connecting to the valve stem and cooperating with the seat ring. Its design and machining accuracy for the valve's sealing and fluid control capabilities are critical.
- Seals (Image Part C) Seals are an important part of lug butterfly valves and are used to prevent fluid leakage. The seals in the construction diagram usually include O-rings, sealing gaskets, etc. The O-rings are located at the contact surface of the valve body and valve stem, and play the role of sealing and preventing leakage. Sealing gasket is installed between the seat ring and the valve plate to ensure that the valve has a good sealing performance in the closed state, to prevent leakage of media.
- The end of the production line capacity (Image Part D) end of the production line capacity is the lug butterfly valve construction diagram needs to be considered one of the important factors. This index indicates the pressure resistance, fluid resistance and opening and closing torque and other parameters of the valve under different working conditions. The end-of-line capacity of the lug butterfly valve must meet the relevant standards and requirements to ensure its normal operation and long-term reliability in the working process.
- Upper and lower rod bearings (Image Part E) The upper and lower rod bearings are key support parts in lug butterfly valves, used to support the movement of the valve stem. The upper and lower stem bearings in the construction diagram are often made of wear-resistant and corrosion-resistant materials, such as polyimide and polytetrafluoroethylene. The design and material selection of this component will directly affect the smooth movement and sealing performance of the valve stem, which plays an important role in the reliability of the whole valve.
