(1) Flanged butterfly valve (2) Wafer butterfly valve (3) Bellow butterfly valve (4) Welded butterfly valve Note the fluorine butterfly valve: 1. Since the multi-layer soft stacked ring seal Fixed on the valve plate, when the valve plate normally open state of the sealing surface to form a positive erosion, with the erosion, directly affect the sealing performance. 2, Constrained by the structural conditions The structure does not adapt to do the following valve DN200, because the overall structure of the valve plate is too thick, large flow resistance. Lining fluorine butterfly valve product use: D371F46 folder clamp fluorine butterfly valve for a variety of concentrations of -50 ℃ ~ 150 ℃ aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants, FEP also For a variety of concentrations of strong alkali organic solvents and other corrosive gases, liquid medium pipeline use. Lined fluorine butterfly valve features: When the counter-current state, the seal between the valve plate and the valve seat by the torque of the actuator so that the valve plate. As the pressure of the reverse medium increases, the positive pressure between the valve plate and the valve seat is less than the pressure of the medium. The deformation stored by the spring of the adjusting ring after the load is absorbed can compensate for the tight pressure on the sealing surface of the valve plate and the valve seat Play a role in automatic compensation. Therefore, unlike the prior art, the utility model has the advantages that the soft and hard multi-layer sealing ring is mounted on the valve plate and is directly mounted on the valve body, and an adjusting ring is provided between the pressing plate and the valve seat which is a perfect bidirectional hard sealing method . It will replace gate and ball valves. Search Keyword: More Valve Technical Articles Valve Products Supply Information
Kiln For Gold Extraction
The device has the following characteristics:
1.Wide application field: the device can regenate various types of activated carbonon by adjusting the angle and rotational speed of furnace pipe.
2.Regeneration activated carbon in the oven retention time 40 minutes, which is applicable to the regeneration levelofall kinds of grain particles, for coal activated carbon also has good regeneration effect.
3.High degree of automation:the device operation achieves automatic control,with man-machine interface+Intelligent instrument control,reduces the operating workers and the labor intensity is low.
4.High recovery rate of Iodine value:basically returned to a new carbon levels above 90%.
5.Low carbon loss:≤1-2%(Coal carbon)But slightly higher than the JHR-O series activated carbon fuel diesel reclamation equipment
6.Easy installation, covers an area slightly larger, but the small space height requirements, large installed power.
Long service life:The core components furnace tube using thick wall (10 mm thick) 1200 ℃ high temperature resistance, corrosion resistant special stainless steel pipe.
