Buna Nitrile NBR Universal Diaphragm Repair Kit For SCG353A047 SCG353A045 SCG353A046 Solenoid Valve
The operating temperature range and pressure range of the diaphragm itself depend on the type of glue, fabric and structure. The diaphragm can work at - 50 ~ 100 ℃, 0.4 ~ 0.8MPa; the fluororubber and silicone rubber diaphragm can work at - 80 ~ 232 ℃. The chlorophenol rubber diaphragm can work under the pressure of 0.4 ~ 0.8MPa, with good air tightness, aging resistance, and the service life equal to that of engine overhaul.
The harsh working environment of the pulse valve diaphragm, the normal temperature and high-strength diaphragm resistant to high and low temperature, make the service life of the diaphragm accurately and effectively carry out the operation synchronously with other control components, ensure the impulse compressed air injection, and ensure its normal operation and long service life ≥ 1 million times or 3 years even under the harsh working conditions.
Mechanism and performance: it is composed of single or multi-layer glued on both sides, and there are also rubber free fabrics. According to its shape, it can be divided into two parts. According to the use requirements can be made of different rubber, different fabrics of the diaphragm. The properties of NBR and polysulfide rubber blends for diaphragms, the properties of rubber compounds for canvas disc diaphragms (often called diaphragms), and the properties of some silicone rubber, fluororubber and chlorohydrin rubber diaphragms developed in recent years are as follows.
The operating temperature and pressure range of the diaphragm itself depend on the type of glue, fabric and structure. The diaphragm can work at - 50 ~ 100 ℃, 0.4 ~ 0.8MPa; the fluororubber and silicone rubber diaphragm can work at - 80 ~ 232 ℃; the chlorohydrin rubber diaphragm can work at 0.4 ~ 0.8MPa, with good air tightness, aging resistance, and service life equal to that of engine overhaul.
