Product Introduction
Quick-connect electromagnetic pulse valve. This electromagnetic pulse valve has high sensitivity, large exhaust volume and stable operation. It is an improvement on the new right-angle electromagnetic pulse valve. A new type of angle electromagnetic pulse valve with the characteristics of convenient installation, use and maintenance. It is a new type improved on the basis of the traditional right angle electromagnetic pulse valve.
Operating principle of electromagnetic pulse valve
The diaphragm divides the electromagnetic pulse valve into two air chambers, front and rear. When the compressed air is turned on, the compressed air enters the rear air chamber through the throttle hole. At this time, the rear air chamber The chamber pressure presses the diaphragm assembly close to the output port of the valve, and the electromagnetic pulse valve is in a closed state.
The electrical signal of the pulse injection controller causes the armature of the electromagnetic pulse valve to move backward, the vent hole in the rear air chamber of the valve opens, the rear air chamber quickly loses pressure, the diaphragm assembly moves backward, and the compressed air passes through the valve outlet. Injection, the electromagnetic pulse valve is open.
When the electrical signal of the pulse injection controller disappears, the armature of the electromagnetic pulse valve is reset, the vent hole of the rear air chamber is closed, the pressure in the rear air chamber increases, causing the diaphragm assembly to be close to the output port of the valve, and the electromagnetic pulse valve is in the Closed status.

Technical requirements
The working pressure of the electromagnetic pulse valve is that the medium is air that has been treated with oil and water removal.
. Under the nominal air source pressure of the electromagnetic pulse valve, when the operating voltage of the pulse valve is the rated voltage, the opening response time of the pulse valve should be less than
. The electromagnetic pulse valve should be able to withstand the air source pressure. .
Under the condition that the room temperature is between degrees and the relative humidity does not exceed , the electromagnetic pulse valve coil can withstand the voltage of the outer shell without any breakdown for a long time.
, the electromagnetic pulse valve should be able to work normally after enduring vibration with a frequency of , a full amplitude of , and a duration of .
Under normal use conditions, the cumulative service life of the electromagnetic pulse valve diaphragm should be greater than 10,000 times.
There is no obvious coating peeling, scratches, burrs or other damage on the surface of the electromagnetic pulse valve.
Characteristics of pulse valve
Safety
For corrosive media, it is better to choose electromagnetic pulse valves made of stainless steel or alloy. For highly corrosive media, the isolation diaphragm type must be used.
Products with corresponding explosion-proof grades must be selected for explosive environments. Waterproof and dustproof varieties should be selected for outdoor installation or dusty occasions.
The weighing pressure should exceed the maximum working pressure in the pipe.
2. Applicability
Qualitative characteristics, parameters, environmental conditions, source conditions, system accuracy
3. Reliability
Working life, this item is not included in the factory test items and is a type test item.
The working system is divided into three types: long-term working system, recurring short-time working system and short-time working system.
When the working frequency and operating frequency are high, the structure should be a direct-acting solenoid valve, and the power supply should be AC.
, action reliability
Four economy
The selection of pulse valve must be based on safety, applicability and reliability, and then consider the economy of the valve. Economy not only refers to the selling price of the product, but also gives priority to its function and quality as well as the cost of installation, maintenance and other accessories.
More importantly, the cost of a pulse valve in the entire automatic control system and even the production line is very small. If you choose it wrongly for the sake of small gains, the damage caused will be huge.
