Translation of JOIL Pulse Valve Diaphragm Properties
As the core sealing and control component of JOIL pulse valves, the
diaphragm has the following main properties:
Material Characteristics:
- 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.
Temperature Adaptation Range:
- NBR diaphragms: -30°C to 120°C
- FKM diaphragms: -20°C to 200°C, some models can handle higher
temperatures.
Physical Properties:
- 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:
- Service life can exceed 1 million cycles under standard conditions.
- High-quality FKM diaphragms can extend service life to over 2
million cycles.
Structural Design:
- 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:
Industrial Dust Removal Systems
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.
Chemical Industry
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.
Food Industry
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.
Automotive Manufacturing
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.
High-Temperature Environment Industries
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.
Supplementary Notes on Industry-Specific Terms
- 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.
