4、 When disassembling the flange ball valve, the bolts and nuts on the flange shall be fixed first, then all nuts shall be slightly tightened, and finally fixed with force. If individual nuts are forced to be fixed first, and then other nuts are fixed, the gasket surface will be damaged or broken due to uneven pressure between the flange faces, resulting in leakage of media from the valve flange butt joint.

We guarantee that each product is qualified before delivery and that the skin fabric layer with non-metallic compensator is used. How many do you know
Our factory is an authoritative enterprise specializing in the consumption of metal and square non-metallic compensators. What do you know about the skin of the fabric layer? The desulfurization layer of the power plant requires not only high temperature, but also anti-corrosion acid and alkali performance of the medium. In this case, the polytetrafluoroethylene film is indispensable, and the cost is certainly a little high. The inner and outer layer of tetrafluoroethylene is also an important material to ensure the quality and quantity of the insulation layer ceramic fiber layer, Noise elimination and shock absorption: fiber fabrics (silicone rubber cloth, fluororubber cloth) and insulation cotton have the functions of noise elimination and vibration isolation, which can effectively reduce the noise and vibration sealing of boiler, fan and other systems. There is a relatively complete consumption assembly system, and fiber compensator can ensure no leakage.
No reverse thrust: because the main material is fiber fabric, which can not be transmitted easily, the use of fiber compensator can simplify the design, prevent the use of large bearings, and save a lot of data and labor.
The non-metallic compensator is a common flexible component. With its common performance, it is widely used in fluid escort pipelines and equipment in mining, metallurgy, power, cement building materials, nuclear energy, petrochemical and other industries.
Stainless steel wire mesh, wired glass fiber cloth, asbestos cloth, glass fiber blanket, asbestos cord cloth, industrial canvas, silicone rubber glass fiber fabric. These layers are powerful heat insulation and temperature resistant layers!
