Customize Black NBR 1 inch Air Medium Pulse Valve Diaphragm D25 in
Dust Bag Filter System
It is composed of single or multiple layers coated on both sides,
and it is also made of rubber without fabric. Membrane pressure
method according to its shape. According to the requirements of the
use of different materials can be manufactured, different fabric
diaphragm. The properties of the butyronitrile and polysulfide
blends used in the film, the properties of the rubber used in the
canvas disc film (often called diaphragm), and some silicone
rubber, fluorine rubber and chlorohydrin rubber films developed in
recent years.
The operating temperature and pressure range of the diaphragm
itself depends on the rubber, fabric and structure. The diaphragm
can work at -50~100 c and 0.4~ 0.8mpa. Fluorine rubber and silicone
rubber diaphragm can work at -80~232 c. Chlorohydrin rubber
diaphragm can work under pressure of 0.4~ 0.8mpa, good air
tightness, aging resistance, life and engine overhaul life is
equal.

Note and Instruction of Diaphragm
1, Diaphragm (rubber or fabric reinforcement in rubber diaphragms)
is a precision functional part used for checking pressure or
changing fluid pressure into driving power
2, Diaphragm has been widely used in automobiles, controllers,
household gas facilities and appliances with form of pressure
sensors, actuators, On-Off switchs
3, Fabric-reinforcements in rubber diaphragms utilize a layer of an
engineered fabric material as parts of the diaphragm construction.
This layer of fabric give tremendous
design felxibity
4, A very thin-walled diaphragm can withstand high pressures while
remaining very flexible and responsive to minior pressure
variations
5, Fabrics made of polyester, nylon and silk ard commonly used for
most applications, fabric used for those applications exposed to
high temperature. For those applications
that require extremely high strength
6, All types of elastomers, such as nitrile, EPDM, fluorocarbon,
neoprene, silicone, fluorosilicone, can be used in the
fabric-reinforced diaphragms.
7, Fabric-reinforced diaphragms offer advantanges of no leakage, no
lubrication, no breakaway force, no friction, high strength,
functionality over wide pressure ranges, low
cost, simple design, versatility
The Working Principle of Diaphragm
The pulse valve diaphragm divides the pulse valve into the front
and rear air Chambers. When the electromagnetic pulse valve is
connected with the clean compressed air in the dust removal system
of the pulse bag filter, the compressed air enters the rear air
chamber through the throttle hole
In the closed state, the pulse control device outputs signals to
make the armature of the pulse valve move. After the valve, the air
chamber vent is opened, and the air chamber quickly loses pressure,
making the diaphragm move backward and the compressed air is
sprayed through the valve's air outlet. The pulse valve is in the
open state, and the injection begins
After the air chamber vent is closed, the air chamber pressure
rises to make the pulse valve diaphragm close to the air outlet of
the valve. The pulse valve is in a closed state, and the injection
stops. The air volume of the injection time is controlled by the
controller.
