Product Description:

As the core sealing and control component of JOIL pulse valves, the diaphragm has the following main properties:

• Common materials include Nitrile Butadiene Rubber (NBR) and Fluororubber (FKM).
• NBR diaphragms have good oil resistance and wear resistance, suitable for oil-containing compressed air conditions.
• FKM diaphragms exhibit excellent high-temperature resistance and corrosion resistance.
• Reinforced structure for improved tear resistance and service life.

• NBR diaphragms: -30°C to 120°C
• FKM diaphragms: -20°C to 200°C, some models can handle higher temperatures.

• Uniform thickness, typically ranging from 1.5mm to 3mm.
• High elastic recovery rate, usually ≥85%.
• Tensile strength ≥15MPa and tear strength ≥30kN/m.

• Service life can exceed 1 million cycles under standard conditions.
• High-quality FKM diaphragms can extend service life to over 2 million cycles.

• Adopts a lip-sealing structure with a lip height of 0.5–1mm.
• Positioning structure for synchronization of movement.

These properties ensure efficient and stable blowing control in dust removal systems, reducing downtime caused by diaphragm failure.

Key Technical Terminology Note:

Fabric Reinforcement Layer:

A layer of high-strength fiber fabric embedded in the diaphragm material, enhancing resistance to stretching and tearing without compromising elasticity.

Lip-Sealing Structure:

A sealing design with a raised "lip" that deforms under pressure to block air leakage.

Pulse Pressure Impact:

Instantaneous pressure change when the pulse valve releases compressed air, which the diaphragm must withstand without permanent deformation.

Applications:

As a crucial element of the pulse blowing system in baghouse dust collectors, JOIL pulse valve diaphragms are extensively utilized in various industries like iron and steel, cement, and electric power. These diaphragms have the ability to swiftly open and close to regulate the pulse blowing of compressed air, facilitating the cleaning of dust from filter bags. This not only enhances dust removal efficiency but also prolongs the lifespan of the filter bags.

Certain JOIL pulse valve diaphragms are crafted from corrosion-resistant materials such as fluororubber (FKM), known for their exceptional corrosion resistance. This makes them suitable for applications in chemical production processes to manage the flow and pressure of corrosive gases or liquids—such as in the handling of acid-alkali solutions and gas control for chemical reaction kettles.

The food processing sector imposes stringent hygiene standards. When JOIL pulse valve diaphragms are manufactured with food-grade compliant materials, they can be employed for pneumatic control in food packaging, material transportation, and other processes, guaranteeing the safety and cleanliness of the food production environment.

Dust and fumes generated during automotive manufacturing operations like painting and welding necessitate purification through dust removal equipment. JOIL pulse valve diaphragms can be integrated into the dust removal systems of automotive manufacturing facilities to maintain clean workshop air, fostering a conducive work environment and enhancing product quality.

Industries dealing with high-temperature processes such as metallurgy and ceramics require effective purification of high-temperature flue gas. JOIL pulse valve diaphragms designed to be high-temperature-resistant can operate reliably under extreme heat conditions, withstanding pulse pressure impacts and ensuring efficient dust cleaning in such environments.

• Baghouse Dust Collector: A fundamental dust removal apparatus that utilizes filter bags to trap dust particles from gas. JOIL pulse valve diaphragms enable the blowing off of dust adhering to the filter bags, preserving their filtration effectiveness.
• Food-Grade Compliant Materials: Materials meeting international food safety standards, ensuring non-toxicity and safety for food contact.
• High-Temperature Flue Gas: Flue gas generated during high-temperature processes like metal smelting, requiring diaphragms with high-temperature resistance to prevent material deformation.
