Cast steel flanged ball valve Q41F
Other Products
I. Introduction:
The closing element of the cast steel flanged ball valve is a sphere, which rotates around the center line of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. The floating ball valve adopts a specially designed double-inclined elastic sealing ring, which effectively reduces the friction between the sphere and the sealing ring and decreases the operating torque. When the medium pressure is low, the contact area between the sealing ring and the sphere is small, resulting in a large specific sealing pressure to ensure reliable sealing. When the medium pressure is high, the contact area between the sealing ring and the sphere also increases accordingly, so the sealing ring can withstand a large medium thrust without damage, ensuring reliable sealing. The valve seat structure with elasticity and automatic compensation function enables easy opening and closing at high temperatures. The sphere and valve seat undergo special hardening treatment to ensure reliable sealing, high temperature resistance, wear resistance, corrosion resistance, and long service life. The sphere and valve seat have good shear and self-cleaning functions, making them suitable for controlling media containing particles and fibers. They are widely used in industries such as petroleum, chemical, pharmaceutical, food, light industry, and electric power, and are suitable for controlling high-temperature fluid media or fluids containing particles and fibers, especially for boilers, coal injection, and scaled or frozen transmission pipelines in power stations and metallurgical industries.
II. Performance Features:
① Fire-resistant structure: As required by users, the ball valve can be designed with a fire-resistant structure. In case of a fire that burns the sealing ring, all sealing parts of the ball valve can form a metal-to-metal hard sealing structure, effectively preventing the medium from spreading and stopping the fire from spreading;
② Anti-static structure: As required by users, the ball valve can be designed with an anti-static structure, that is, a conductive spring is installed between the sphere and the valve stem, so that static electricity generated during the opening process of the valve can be introduced into the pipeline and then into the ground through the set static electricity channel, achieving the purpose of eliminating static electricity, avoiding static ignition that may ignite the medium, and ensuring system safety.
III. Actuator:
The new series GT pneumatic actuators are adopted, available in double-acting and single-acting (spring return) types, with rack and pinion transmission, ensuring safety and reliability; for large-diameter valves, the series AW pneumatic actuators with fork-type transmission are used, featuring a reasonable structure and large output torque, and are available in double-acting and single-acting types.
1. Gear-type double pistons, with large output torque and small volume.
2. The cylinder is made of aluminum alloy, which is light in weight and beautiful in appearance.
3. Manual operating mechanisms can be installed at the top and bottom.
4. The rack-type connection can adjust the opening angle and rated flow.
5. The actuator can be optionally equipped with electrical signal feedback indicators and various accessories to realize automated operation.
6. The IS05211 standard connection facilitates the installation and replacement of the product.
7. The adjusting screws at both ends allow the standard product to have an adjustable range of ±4° at 0° and 90°, ensuring synchronization accuracy with the valve.
