First, the outline of the PTFE lined-lined discharging valve
This series of products is an extension of PTFE lined discharging valve. It is designed for the opening and closing control of various corrosive media. The flanges at both ends of the valve are of different sizes. One end is a standard flange and one end is matched with the bottom hole of the reaction kettle. The flange is very convenient to be connected to the bottom of the reactor. The structure is floating straight-through, the connection form is flange, the valve shell is made of carbon steel lined with PTFE lining, the valve body is made of the valve insert integrated metal insert, and has good corrosion resistance, opening and closing. Flexible, fast and beautiful, high strength and durable. It is the most widely used corrosion resistant valve in modern industrial processes.
Second, the working principle
The working principle of lining PTFE lined discharge valve is to make the valve unblocked or occluded by rotating the valve disc. The valve flap and the inner side of the valve body are all made of ptfe lining. It has light switch, small volume and sealing. Reliable, simple structure, convenient maintenance and wide range of use.
Third, the use
The lining PTFE lined discharge ball valve adopts ptfe lining technology. The valve body is cast by investment casting. The strength is high and the appearance is smooth. The overcurrent parts in contact with the liquid are all ptfe, so it can be used at -50 °C ~ 180 °C. Long-term use in a range of corrosive pipelines, pipeline work.
Fourth, the design features
The basic series of the discharge ball valve is Q41F type. In addition to the general ball valve, the fluid resistance is small, the opening and closing speed is fast, and the structure is simple. The following advantages are also achieved:
1. Adopting full-bore, floating ball structure, the valve can be closed without leakage within the entire pressure range, which is more convenient for the pipeline sweeping and pipeline maintenance of the pipeline system;
2. The ball valve with ptfe lining layer has high chemical stability and can be applied to any highly corrosive chemical medium. 3 The opening and closing member sphere and the valve stem casting (forging) are integrated to prevent the valve from being caused by pressure changes. The possibility of the rod impacting the pressure bearing member fundamentally guarantees the safety in use;
4. The structure is compact and reasonable, the valve body space is the smallest, and the medium retention is reduced. In addition, the special molding process makes the sealing surface density good, and the herringbone ring PTFE packing combination makes the valve reach zero leakage.
