High Flow Rates Diaphragm DB116 For MECAIR Type Solenoid Pulse Valve

High Flow Rates Diaphragm DB116 for MECAIR Type Solenoid Pulse Valve

Pulse valve is by the air flow through the air resistance, air capacity delay effect, so that the input of the long signal into the pulse signal valve class. The diaphragm is a circular membrane of elastic sensitive elements. When the two sides of the membrane are subjected to different pressures (or forces), the membrane moves towards the side with lower pressure, causing the displacement of its center in a certain relation to the pressure difference.

The types of diaphragm are mainly plain diaphragm, vertical chain diaphragm and corrugated diaphragm. The flat diaphragm can be divided into various forms according to whether the peripheral support is fixed, whether the center is open or not, and the stress distribution in the diaphragm area, etc. The most commonly used is the flat diaphragm composed of the circular thin plate with the same section with fixed peripheral.

You can refer to the data of diaphragm (including center distance, etc.) in the following pictures

You know,Diaphragm is one of the most important component in the Pulse Valve and final applicated in Dust Collector Filter System

About the Definition of Pulse Valve Diaphragm

pulse valve diaphragm commonly used material is rubber. The rubber diaphragm is mainly used in valves, regulating valves, automatic mechanical follow-up devices, switches and counters of flow rate, pressure, differential, liquid level, constant temperature and volume thermal compensation, etc. Its advantages are high reliability, good complexity, long working life and low cost. Uniform elastic construction can be used in all kinds of rubber.

The rubber diaphragm has a long service life and can perform the operation synchronously with other control components to ensure the pulse compressed air injection. Even in extremely harsh working conditions, it can guarantee its normal work and long service life.
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. Fluoro rubber and silicone rubber diaphragm can work at -80~232 ℃. Chlorol rubber diaphragm can work under pressure of 0.4~ 0.8mpa, with good air tightness and aging resistance.

The Characteristics of Bag Dust Collector

Adopt the technology of separating pulse and stopping wind, which overcomes the shortcomings of conventional pulse dust collector and separating reverse dust collector, strong ability of dust removal, high dust removal efficiency, low emission concentration, small air leakage rate, less energy consumption, less steel consumption, less area, stable and reliable operation and good economic benefit. It is suitable for dust gas purification and material recovery in metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry.

The purpose of thoroughly cleaning ash can be achieved in one time through the use of chamber stopping wind pulse spraying, so the period of ash cleaning is prolonged, the energy consumption of ash cleaning is reduced, and the air pressure consumption can be greatly reduced. At the same time, the fatigue degree of filter bag and pulse valve is reduced correspondingly, thus the life of filter bag and valve disc is increased exponentially.
