Electromagnetic pulse valve MG-DMF-ZJ dust removal accessories

Details


Dongguan Meijun specializes in sand blasting room dust collector accessories, dry dust collector accessories including electromagnetic pulse valve, dust bag, pulse controller, air control components, etc.

The electromagnetic pulse valve is specially designed for the application of dust removal equipment. It has a high flow rate, long life and momentary opening and closing valve. Its opening and closing is controlled by an electromagnetic pilot. Due to its advanced design, the valve has good fluidity. The rubber diaphragm has low pressure loss, which ensures that the electromagnetic pulse valve opens quickly when it receives a pulse electrical signal and closes quickly after completing the pulse.

High-purity aluminum alloy die-cast valve body, electromagnetic pulse valve diaphragm composed of top-level special inclusions, which makes the diaphragm have extremely high tensile strength, aging resistance and low wear, which makes Meijun MAGIN electromagnetic pulse valve blow. Service life is over 1 million times or three to five years without damage.

The electromagnetic pulse valve coil is higher than the national standard insulation injection at a protection level of} P65. It is fully encapsulated and covered with copper enameled wire. The number of turns is higher than the national standard. 360 "rotation on the spool, and the junction box can be rotated to install 4 x 900, which prevents rainwater from entering when exposed to the open air, which greatly facilitates installation at different angles.

product description

The angle between the input port and the output port of the MG-DMF-ZJ type electromagnetic pulse valve is 90 °, which is called a right-angle valve. The input and output ports are external threads, and are equipped with compression nuts. The pipe or injection pipe is directly inserted into the conical seals of the input and output ports of the valve, and the compression nut is tightened. The installation is convenient, the air flow is smooth, and it can provide the ideal dust cleaning pulse, which is suitable for the cleaning of various filter units.

MG-DMF-ZJ type electromagnetic pulse valve input port and an output port angle is 90 DEG angle valve, the input and output for external thread, and is equipped with a pressing nut, gas tank (gas) on spools or blowing Z directly inserted in the valve of the input and output of conical sealing ring and tighten nut, convenient installation, smooth airflow, provides an ideal cleaning Qimai, applicable to all kinds of filter element cleaning.

The diaphragm is made of top-grade finished diaphragm. Its quality is comparable to that of imported products. It has super stretchability. Each diaphragm can pass the strict inspection before entering the assembly line and every finished valve is tested after assembly. .

Diaphragm with the top end of the film, the quality and import comparable, super tensile, each piece of the film are strictly detected before entering the assembly line, the assembly after each finished product valve testing, the indicators are all qualified before the factory

Installation method tips

1. The injection air source of the electromagnetic pulse valve is provided by the air box (air bag). There are two types of gas distribution boxes: square and round. The round gas distribution box has better pressure resistance. When the submerged electromagnetic pulse valve is used, the square The gas separation box is more convenient to install.

2. The cross-sectional area and length of the air separation tank determine the gas storage volume. Its volume should meet the pressure of the group of pulse valves after each injection. The remaining pressure in the tank is not less than 50% of the pressure before injection. Gas tank inflation speed, the speed should meet the group of pulse valve within 10s after each injection to restore the gas in the tank to the pressure before injection.

3. The pulse valve should be installed on the upper or side of the gas distribution box. When installing the side, the center of the input end of the pulse valve should not be lower than the center line of the side of the gas distribution box. It should be installed in a horizontal or downward position, not in an upward position.

4. The blowing hole of the blowing pipe should be less than about 18, the opening is: 8-32mm (far from small to large), and the blowing pipe is preferably 200-400 away from the bag opening.
