Check the pneumatic valve open-close part on the strength of the medium flow to open or closed, to prevent the backflow medium pneumatic valve check pneumatic valve.
Check pneumatic valve belong to automatic pneumatic valve class, mainly used for one-way flow of medium pipeline, only allowed to medium flows in one direction, in order to prevent accidents.
To check the pneumatic valve and what are the different forms of classification?
check pneumatic valve, nominal pressure or pressure, PN1. 0 - 16. 150 - 0 mpa, ANSI类 900、JIS10- 20 k or nominal diameter diameter: DN15 ~ 900, NPS 1/4 ~ 36 connection mode: flange, butt welding, thread, socket and other applicable temperature: - Pneumatic valve body material: 196 ℃ ~ 540 ℃ WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8, 304). 、CF3( 304L) 、CF8M( 316). 、CF3M( 316 l) 、Ti。 Choose different material, check the pneumatic valve: can be respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media.
general formula aerodynamic lift check valve should be installed in horizontal pipe road, vertical lift check pneumatic valve and hand movement valve is generally installed in a vertical tube road, and the medium flows from bottom to top.
swing check pneumatic valve installation position is not restricted, are normally installed in horizontal pipe, but also can be installed in vertical lines, or pour material on the pipeline.
: check the pneumatic valve is installed, should pay special attention to flow direction of medium, should make medium and normal flow direction with the direction of the arrow indicating the pneumatic valve, otherwise it will be truncated normal flow of the medium. Hand moving valve should be installed at the bottom of the pump suction pipe. :
check pneumatic valve is closed, will be in the middle water hammer pressure tube, serious will cause the damage of the pneumatic valve and pipeline or equipment, especially for big or high pressure pipe lines, so should check the height of the pneumatic valve selection is attention.
check pneumatic valve, also known as a one-way pneumatic valve or non-return valve, its purpose is to prevent the backflow medium pipeline. The pump suction style pneumatic valve also belong to the check valve class. Check according to the structure, pneumatic valve can be divided into the lift check pneumatic valve, swing check valve with type check three kinds of pneumatic valve. Aerodynamic lift check valve can be divided into vertical and horizontal two kinds. Swing check pneumatic valve is divided into single type, more than double disc type and disc type 3 kinds. Check the pneumatic valve for straight-through processing, the above several check pneumatic valve in the connection form can be divided into the thread connection, flange connections and welding of three.
can be divided into the lift check pneumatic valve, swing check valve type check three kinds of pneumatic valve. Pneumatic valve can be divided into vertical lift check check pneumatic valve and horizontal check pneumatic valve two kinds. Swing check pneumatic valve is divided into single type check pneumatic valve, double disc type check check pneumatic valve of pneumatic valve and valve type 3 kinds. Check pneumatic valve, pneumatic valve straight through the check for the above several check pneumatic valve in the connection form can be divided into the threaded connection check pneumatic valve, flange connection, check the pneumatic valve and welding check three kinds of pneumatic valve.
