Check the pneumatic valve model establishment method

check flow pneumatic valve refers to rely on the media itself, and automatically open, her breath valve, used to prevent the backflow medium pneumatic valve, also known as non-return pneumatic valve, pneumatic valve, one-way flow pneumatic valve, pneumatic valve and back pressure. Check pneumatic valve belongs to a kind of automatic pneumatic valve, its main role is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium.
check pneumatic valve ( The Check Valve: according to its structure, can be divided into the lift Check pneumatic Valve, swing Check Valve and butterfly Check three kinds of pneumatic Valve. Aerodynamic lift check valve can be divided into vertical and straight-through type two kinds. Swing check pneumatic valve is divided into single type, more than double disc type and disc type 3 kinds. Butterfly check valve pneumatic valve butterfly valve, butterfly for single, the above several check pneumatic valve in the connection form can be divided into the thread connection, flange connection, welding and clamp connection of four.

check the pneumatic valve model establishment method: such as HH - C in order
check additional number of pneumatic valve: HH micro resistance slowly-closing check pneumatic valve, pneumatic valve, BH insulation check HQ the ball type check pneumatic valve;
(1) check pneumatic valve type: H representative check pneumatic valve;
2 check pneumatic valve connection: flange, welding, the clip;
(3) check pneumatic valve forms: lift, vertical, swing, double disc type, butterfly;
(4) check pneumatic valve seal: B babbitt, fluorine plastic F, H, M monel alloy stainless steel, rubber, hard alloy, Y W X directly processing;
5] check pneumatic valve pressure: pressure 16 kilograms, PN. - Class mpa, LB - K - LB, day level K；
[6] check pneumatic valve material: Q nodular cast iron, carbon steel, P - C R - , A titanium alloy, the I chrome molybdenum steel;
