Pneumatic valve installation swing check have any specific requirements?
What is the suitable medium?
Let's take you take a look at in detail.
swing check pneumatic valve is a kind of check pneumatic valve, so it's as long as the purpose is used to control the one-way backflow effect, commonly used in pumps, and other important equipment of the exit to prevent medium counter-current damage at the back of the equipment.
swing check pneumatic valve pneumatic disc around the axis of rotation, the fluid resistance is generally less than the aerodynamic lift check valve, it is suitable for large caliber, installation position is not restricted, are normally installed in horizontal pipe, which applies with the occasion of the large diameter. According to the number of the pneumatic valve can be divided into single swing, more than double disc swing and swing three segments. Single swing check generally use pneumatic valve and medium caliber. Large diameter single swing check pneumatic valve is used in the pipeline, to reduce the water hammer pressure, had better use can reduce the water hammer pressure slowly-closing check pneumatic valve. Double disc swing check pneumatic valve with large and medium caliber pipe shall apply. The pneumatic valve, double valve swing check valve structure is small, light weight, is a kind of fast check pneumatic valve; Many disc swing check pneumatic valve is suitable for large diameter pipeline.
swing check the purpose of the pneumatic valve features
swing check pneumatic valve is suitable for the nominal pressure PN1. 0MPa~42. 0 mpa, Class150 - 2500; Nominal diameter DN15 ~ 1200 mm, NPS1/2 ~ 48; Working temperature - 196 ~ 540 ℃ of various pipelines, used to prevent the backflow medium. By choosing different capable person, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea, and other media.
