Metal hard sealed floating ball valve is mainly composed of valve body, valve cover, valve stem, valve core, sealing ring, ball and other components. The valve body and bonnet are usually made of cast or forged steel to ensure the strength and corrosion resistance of the valve. The stem is connected to the valve cover and spool to transfer the operating force. The valve core is equipped with a sealing ring, and the good sealing effect of the valve is achieved by compressing the sealing ring. The ball is matched with the valve spool and the seat to control the on-off of the medium.
Second, the working principle
The working principle of the metal hard sealed floating ball valve is based on the movement of the floating ball, and the contact state between the ball and the seat is controlled by rotating the valve stem. When the valve is closed, the stem rotates with the ball, so that the ball is tightly attached to the seat by pressure action, achieving complete closure. When the valve is opened, the stem separates the sphere and lifts it, allowing the media to flow smoothly.
Iii. Characteristics
1. Excellent sealing performance: Metal hard seal floating ball valve adopts the sealing method between metal and metal, has excellent high temperature resistance, corrosion resistance, can withstand high pressure and intense working environment.
2. Fast reaction speed: Due to the floating ball structure, the metal hard sealed floating ball valve has a fast reaction speed, which is very suitable for situations where the fluid needs to be cut off quickly.
3. Long life and reliability: Metal hard sealed floating ball valve is made of high-strength materials, good corrosion resistance, long life and reliability, reducing the frequency of maintenance and replacement.
4. Good control performance: Metal hard sealed floating ball valve has low operating torque and flexible control characteristics, which can achieve accurate flow control in a wide range.
4. Application field
1. Oil and gas industry: for fluid control in pipeline systems, including transfer, regulation and cut-off.
2. Chemical industry: suitable for fluid control of various chemical media, such as acid, alkali, solvent, etc.
3. Power industry: in power plants and thermal power plants, used to control the flow and pressure of circulating water, water supply, steam and cooling water and other media.
4. Iron and steel metallurgy industry: used for fluid control under high temperature and high pressure conditions, such as gas, gas and liquid metal.
5. Sewage treatment: In the sewage treatment plant, used to control and regulate the flow of sewage, sludge and chemical reagents.
6. Marine engineering: Suitable for offshore platforms, ships and submarine pipelines, and can withstand high water pressure and corrosive environment.
