The DMF-Z type Right angle valve
1. Definition and Purpose
- The DMF-Z type Right angle valve is a specialized electromagnetic pulse valve designed for bag-type dust collectors.
- It serves as the compressed air switch in the pulse bag filter’s ash-cleaning system, controlled by a pulse injection controller. Its primary function is to periodically blow air through filter bags (row by row or chamber by chamber) to remove accumulated dust, maintaining the dust collector’s resistance within a set range and ensuring efficient dust removal and collection.
2. Working Principle
- The valve is divided into front and rear air chambers by a diaphragm.
- Closed State: When compressed air enters the rear chamber through a throttle hole, the pressure forces the diaphragm against the valve’s outlet, keeping it closed.
- Open State: When a signal from the pulse controller energizes the solenoid, the armature moves, opening a vent hole in the rear chamber. This rapid pressure loss allows the diaphragm to retract, releasing compressed air through the valve outlet for pulsed cleaning.
- Reset: Once the electrical signal ends, the armature resets, closing the vent hole. The rear chamber repressurizes, forcing the diaphragm back to seal the outlet, and the valve returns to the closed state.

How does the Venturi tube in the filter bag cage affect the performance of the dust pump system?
The Venturi tube in the filter bag cage affects the performance of the dust pump system in the following ways:
Improving Dust Removal Efficiency
- Enhanced Dust Detachment: During the pulse – jet cleaning process, the Venturi tube causes the high – pressure air from the blowpipe to accelerate as it passes through the narrow throat section. This acceleration creates a negative pressure zone, which induces a large amount of surrounding air to be sucked into the filter bag. The combined effect of the high – pressure air and the induced air causes the filter bag to expand and contract rapidly, generating strong vibrations. These vibrations are highly effective in dislodging dust particles adhered to the filter bag surface, even those that are difficult to remove, thereby improving the overall dust removal efficiency of the system.
- Thorough Cleaning of Filter Bags: The Venturi – induced air flow helps to ensure a more uniform cleaning of the filter bags. The air is distributed evenly throughout the filter bag, preventing uneven cleaning and reducing the likelihood of dust build – up in certain areas. This thorough cleaning helps to maintain the filtration performance of the filter bags over time, allowing them to continue to effectively capture dust particles and prevent dust from escaping into the atmosphere.
Reducing Energy Consumption
- Efficient Use of Compressed Air: The Venturi tube enables the dust pump system to achieve a significant cleaning effect with a relatively small amount of high – pressure compressed air. By inducing a large volume of surrounding air, it supplements the cleaning air volume, reducing the reliance on a large – volume supply of high – pressure air. This efficient use of compressed air helps to lower the energy consumption of the air compressor that supplies the compressed air, resulting in energy savings for the entire dust pump system.
- Optimized Cleaning Cycles: Due to the enhanced dust removal efficiency provided by the Venturi tube, the frequency of cleaning cycles can be reduced. The filter bags remain clean for longer periods, requiring less frequent activation of the pulse – jet cleaning system. This reduction in the number of cleaning cycles further contributes to energy savings, as each activation of the cleaning system consumes a certain amount of energy.
Protecting the Filter Bags and System Components
- Reduced Mechanical Stress on Filter Bags: The gentle yet effective cleaning action of the Venturi – enhanced air flow helps to reduce the mechanical stress on the filter bags. The even distribution of air and the controlled expansion and contraction of the filter bags during cleaning minimize the occurrence of local stress concentrations, which can lead to premature wear and tear of the filter bags. By prolonging the service life of the filter bags, the Venturi tube helps to reduce the frequency of filter bag replacements, thereby reducing maintenance costs and downtime of the dust pump system.
- Prevention of System Clogging: The efficient dust removal achieved by the Venturi tube helps to prevent dust from accumulating and clogging the filter bags, as well as other components of the dust pump system such as the ducts and the dust – collecting hopper. Clogging can lead to increased resistance to air flow, reduced system efficiency, and potential damage to the system. By maintaining a clean and unobstructed flow path, the Venturi tube helps to ensure the smooth operation of the dust pump system and protects its various components from damage caused by dust build – up.

Can you provide more details about the Venturi tube in the filter bag cage?
Here are the detailed descriptions about the Venturi tube in the filter bag cage:
Structure
- The Venturi tube consists of a convergent section, a throat section, and a divergent section. The convergent section gradually narrows the flow channel of the gas, causing the gas velocity to increase and the pressure to decrease. The throat section is the narrowest part of the Venturi tube, where the gas reaches the maximum velocity and the minimum pressure. The divergent section then gradually expands the flow channel, allowing the gas velocity to decrease and the pressure to recover. In the filter bag cage, the Venturi tube is usually made of stainless steel or other corrosion – resistant materials to ensure its durability and reliability in harsh industrial environments.
Working Principle
- When the pulse – jet cleaning system is activated, high – pressure air is injected into the filter bag through the blowpipe. As the air passes through the Venturi tube, the constricted throat section causes the air to accelerate. According to the principle of conservation of energy, the increase in air velocity leads to a decrease in static pressure, creating a negative pressure zone. This negative pressure zone induces a large amount of surrounding air to be sucked into the filter bag. The combined effect of the high – pressure air from the blowpipe and the induced air causes a rapid expansion and contraction of the filter bag, generating a strong vibration that effectively detaches the dust adhered to the filter bag surface.
Functions
- Enhanced Dust Removal Efficiency: By inducing a large volume of additional air, the Venturi tube significantly increases the air volume and momentum entering the filter bag during the cleaning process. This powerful air flow can more effectively dislodge the dust particles, especially those that are firmly attached to the filter bag, thereby improving the dust removal efficiency and ensuring the cleanliness of the filter bag.
- Reduced Energy Consumption: The Venturi tube enables the use of a relatively small amount of high – pressure air to achieve a large – scale cleaning effect. It utilizes the energy – saving principle of inducing surrounding air, reducing the need for a large amount of high – pressure air supply. This helps to lower the energy consumption of the dust removal system, resulting in significant energy savings and reduced operating costs.
- Uniform Cleaning: The design of the Venturi tube ensures a relatively uniform distribution of the air flow entering the filter bag. This uniformity helps to avoid local over – cleaning or under – cleaning, ensuring that the entire filter bag is cleaned evenly. As a result, the service life of the filter bag is prolonged, and the filtration performance of the dust collector is maintained at a stable level.
