Product description of Forged Steel Ball Valve
1. Forged steel ball valve is based on the needs of users. In order to meet the requirements of vulcanization and cracking in vulcanization environment, this series of high pressure forged steel balls are designed, selected, manufactured, tested, surface treated and painted in strict accordance with NACE standards.
2. This series of ball valves are not only made of a wide range of materials, but also the internal parts are made of color, the surface is made of nickel plated 316 material, and the sealing ring is made of special polymer material. The valve is not only anti-corrosion, strong vulcanization resistance, good fire prevention, anti-static, good sealing performance, wide range of pressure and temperature, complete with full bore and reduced bore, and can be equipped with a variety of driving devices. It is an ideal valve choice for chemical industry, oil torch refining, natural gas exploitation and transmission systems. Main functions:
3. When the stagnant medium in the cavity of the valve is abnormally pressurized due to temperature changes, the medium pressure will push the valve seat away from the ball to achieve the effect of automatic pressure relief, and the valve seat will automatically reset after pressure relief.
4. In addition to general sealing, the special sealing structure of the valve seat can play an emergency rescue role in case of leakage due to seal ring damage.
When fire or abnormal temperature burns or softens the sealing ring of the valve seat. The operation of the valve is still reliable. At the same time, the valve seat and the ball form metal to metal, achieving a temporary sealing effect, preventing the further expansion of the fire, which is in line with the provisions of ap16fa.
5. Unscrewing the discharge device can check whether the valve seat leaks, or discharge the residue in the middle chamber to reduce the unilateral pollution of the medium to the valve. Under the working condition, when the valve is fully open or closed, the valve stem stuffing box can be replaced.
6. The valve stem is sealed with PTFE packing and O-ring, which is especially suitable for gas medium. The moving part of the valve rod adopts high-quality SF self-lubricating bearings to reduce the friction coefficient and reduce the operating torque.
Operation process of Forged Steel Ball Valve
(1) Before preparing to connect with the pipe, flush and remove the remaining impurities in the pipe (these substances may damage the valve seat and ball).
(2) During installation, please do not use the actuator of the valve as the lifting point to avoid damaging the actuator and accessories.
(3) This type of valve should be installed in the horizontal or vertical direction of the pipeline.
(4) The pipeline near the installation point shall not be sagged or bear external forces. Pipe supports or supports can be used to eliminate the deviation of the pipeline.
(5) After connecting with the pipe, please cross lock the flange connecting bolts with the specified torque.
Industrial applications of Forged Steel Ball Valve
Forged steel ball valve has all performance indexes of ordinary ball valve, superior material density, which can be more suitable for flammable and explosive media. Metal hard sealed ball valve also has high temperature resistance, friction resistance and double flow item inlet and outlet self sealing function. Forged steel ball valve has stable switching performance under the conditions of high frequency, high temperature difference and high pressure difference. At present, it is widely used in papermaking, crude oil, natural gas, petrochemical and all kinds of related industries containing particles, which are easy to wear, erosion and fire.
