BQ45F three-way insulated ball valve
I. Introduction:
The BQ45F three-way insulated ball valve has excellent insulation and cold insulation properties. Its inner diameter is consistent with the pipe diameter, which effectively reduces heat loss of the medium in the pipeline. It is mainly used in various systems such as petroleum, chemical industry, metallurgy, pharmacy, food, etc., to convey high-viscosity media that will solidify at room temperature. As a relatively new type of ball valve, it has unique structural advantages, such as no friction during opening and closing, low wear resistance of the sealing surface, and small opening and closing torque. This can reduce the specification of the matched actuator. Equipped with a multi-turn electric actuator, it can realize medium regulation and tight shut-off. It is widely applicable to working conditions that require strict shut-off, such as petroleum, chemical industry, and urban water supply and drainage.
II. Advantages:
1. Small fluid resistance, with a resistance coefficient equal to that of a pipe section of the same length.
2. Simple structure, small volume and light weight.
3. Tight and reliable, with good sealing performance, and has been widely used in vacuum systems.
4. Easy to operate, with quick opening and closing. It only needs a 90° rotation from fully open to fully closed, which facilitates remote control.
5. Easy to maintain. The ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.
6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, so the medium will not cause erosion to the valve sealing surface when passing through.
7. Wide application range. The inner diameter ranges from several millimeters to several meters, and it can be applied from high vacuum to high pressure.
8. High-platform ball valves can be divided into straight-through type, three-way type and right-angle type according to their channel positions. The latter two types of ball valves are used for distributing media and changing the flow direction of media.
III. Notes for storage, installation and use:
1. During storage, seal all external passages with plugs or cover plates, and store in a dry and ventilated room. For long-term storage, conduct regular inspections to remove dirt, and apply anti-rust oil on the machined surfaces to prevent rusting.
2. Before installation, clean the valve thoroughly and tighten all threaded connections.
3. Adopt the check valve principle, which can only cut off in one direction. When installing, pay attention to the valve marking and take the end to be protected as the valve inlet.
4. When placing an order, specify the flange sealing surface type, pressure class and connection standard.
