The material of the pulse valve diaphragm is crucial for determining its performance. Dahe pulse valve diaphragms primarily use elastomer materials. The common types and their characteristics are described below:
Nitrile Butadiene Rubber (NBR):
Advantages: Good oil resistance, suitable for oil mist environments; moderate elasticity and cost-effective.
Limitations: General temperature resistance (-20℃~120℃), weak ozone aging resistance.
Fluoroelastomer (FKM):
Advantages: Excellent high and low temperature resistance, strong resistance to chemical corrosion and aging; suitable for harsh working conditions.
Limitations: Higher cost, slightly lower elasticity compared to NBR.
Ethylene Propylene Diene Monomer (EPDM):
Advantages: Good weather and ozone resistance, suitable for a wide temperature range.
Limitations: Poor oil resistance, not suitable for oil-containing environments.
Some high-end models utilize composite materials to enhance tear resistance and strength.
Elasticity and Resilience:
The diaphragm requires high elasticity and resilience for quick opening and closing during high-frequency pulse airflow.
Tensile Strength and Tear Strength:
Sufficient tensile and tear strength are crucial to prevent rupture and damage during operation.
Hardness:
Materials with appropriate hardness levels ensure effective sealing without compromising elasticity.
Temperature Resistance:
Choosing the right material based on working temperature is essential.
Sealing Performance:
Precision processing of the diaphragm and valve seat surface ensures complete sealing.
Response Speed:
Quick opening and closing in milliseconds is essential for efficient ash cleaning.
Medium Resistance:
The diaphragm must withstand various elements in compressed air to ensure long-lasting performance.

Working Condition Adaptation: The material is selected according to the temperature of the dust removal system, medium (oil-containing, corrosive gas, etc.), and pulse pressure (usually 0.2~0.6MPa). For example:
Corrosive environments such as waste incineration plants and chemical workshops → fluororubber diaphragms;
Normal temperature and non-corrosive environments such as wood processing and grain processing → nitrile rubber diaphragms.
V. Service Life
Under normal working conditions, the service life of high-quality diaphragms can reach 100,000~300,000 pulse cycles (about 1~3 years), which depends on the material, working temperature, pulse frequency and maintenance conditions. Improper maintenance (such as a large amount of moisture in compressed air leading to accelerated aging of the diaphragm) will significantly shorten its service life.
In conclusion, the core properties of Dahe pulse valve diaphragm can be summarized as "high elasticity, strong sealing, fatigue resistance and strong adaptability". Its performance is directly related to the stable operation of the pulse valve and even the entire dust removal system. When selecting, the material, size and mechanical properties should be comprehensively considered in combination with the actual working conditions.
