Imported high-pressure small ball valve
Imported high-pressure ball valve r is a valve that uses a ball with a circular channel as the opening and closing component. The ball rotates with the valve stem to realize the opening and closing action. When rotating forward/turn, The valve is closed. On reverse rotation/turn, the valve opens. The opening and closing part of the ball valve is a ball with a hole, which rotates around the axis perpendicular to the channel to achieve the purpose of opening and closing the channel. Imported ball valves are mainly used to open and close pipes and equipment media. Imported high-pressure ball valve specification standard size range ~ pressure level ~ B, suitable for medium gas, liquid, valve body material stainless steel, alloy steel, forged steel, suitable for ~ B, working temperature ~ petrochemical thermal power station and other pipes under various working conditions On the road, special considerations have been taken into its design such as safety and resistance to harsh environments. The applicable media are water vapor, oil, nitric acid, acetic acid, urea and other corrosive and strongly oxidizing media.
Main features of imported high-pressure ball valves
When the stagnant pressure in the middle cavity of Germany's R Olschen high-pressure ball valve exceeds the pre-tightening force of the spring, the valve seat retreats away from the ball to achieve the effect of automatic pressure relief. The valve seat automatically resets.
When a fire occurs or the valve seat sealing ring is burned or softened due to abnormal temperature rise, under the action of the spring and medium pressure, the spherical part of the support ring and the ball form metal-to-metal contact to achieve a temporary sealing effect. Prevented the fire from expanding further and complied with the regulations.
The packing gland part of the imported high-pressure ball valve is sealed with R packing and shaped sealing ring double sealing ring, which is especially suitable for gas media. The packing is installed in the packing plate, and a new type of self-lubricating sliding shaft with low friction system can be used at any time. lining to reduce operating torque.
The imported high-pressure small ball valve has small fluid resistance and is the smallest fluid resistance among all ball valves. Even if it is a reduced-diameter ball valve, its fluid resistance is also quite small. The product has undergone very strict tests such as pressure test, leakage test, etc.
