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.
