TAEHA Type Diaphragm for 2 Inch Pulse Valve DH50 2 Inch

Product Description:

The material of the pulse valve diaphragm is the key to determining its performance. Dahe pulse valve diaphragms mostly use elastomer materials. The common types and their characteristics are as follows:

Advantages: Good oil resistance, suitable for working conditions with oil mist; moderate elasticity and low cost.
Limitations: General temperature resistance (usually -20℃~120℃), weak ozone aging resistance.

Advantages: Excellent high and low temperature resistance (-20℃~above 200℃), strong resistance to chemical corrosion, ozone and aging, suitable for high-temperature and strong corrosive working conditions (such as chemical industry, metallurgy industry).
Limitations: Higher cost, slightly lower elasticity than nitrile rubber.

Advantages: Good weather resistance and ozone resistance, resistant to water vapor and weak acid corrosion, and applicable to a wide temperature range (-40℃~150℃).
Limitations: Poor oil resistance, not suitable for oil-containing environments.

Some high-end models will use composite materials (such as rubber combined with fabric skeleton) to enhance tear resistance and strength.

The diaphragm needs to open and close quickly under the impact of high-frequency (several to dozens of times per minute) pulse airflow. Therefore, it must have high elasticity to ensure that the sealing surface fits tightly without leakage; resilience ensures that it is not easy to deform after long-term use.

During operation, the diaphragm will be subjected to tensile force generated by air pressure. Insufficient tensile strength can easily lead to rupture; tear strength prevents further expansion of edges or tiny damaged areas, extending the service life.

The fitting surface between the diaphragm and the valve seat needs to be precisely processed to ensure complete sealing when there is no pulse signal, preventing compressed air leakage, and avoiding energy waste and reduction of dust removal efficiency.

Working Condition Adaptation:

The material selection of diaphragms is based on various factors including the temperature of the dust removal system, type of medium (such as oil-containing or corrosive gas), and pulse pressure (typically 0.2~0.6MPa). For instance:

• Corrosive environments like waste incineration plants and chemical workshops require fluororubber diaphragms.
• Normal temperature and non-corrosive environments like wood processing and grain processing use nitrile rubber diaphragms.

Service Life:

Under regular operating conditions, high-quality diaphragms can last for 100,000 to 300,000 pulse cycles (equivalent to about 1 to 3 years), depending on factors like material, working temperature, pulse frequency, and maintenance. Improper maintenance, such as high moisture content in compressed air leading to rapid aging of the diaphragm, can significantly reduce its lifespan.

In summary, the key characteristics of Dahe pulse valve diaphragms can be described as "high elasticity, strong sealing, fatigue resistance, and excellent adaptability". The performance of these diaphragms directly affects the stable operation of the pulse valve and the overall dust removal system. When selecting diaphragms, it is crucial to consider material, size, and mechanical properties in conjunction with the specific working conditions.
