Product Details

Goyen type 1 Inch Black NBR EPDM Diaphragm G25 in Pulse Dust Valve

Spring damage, pulse valve spring on the spool is easy to damage, the appearance of the pulse valve is long term to blow air to the nozzle, the treatment is to replace the spring.

Rubber mat damage, use time is long, the rubber pad on the pulse valve spool is easy to damage, the appearance of the pulse valve is long to blow air to the nozzle, the treatment is to replace the rubber mat

Valve core dirt, due to the air intake is not clean, cause the dirt accumulation at the valve core, the appearance is caused by the nozzle long air intake or power pulse valve does not work, the treatment is to clean the valve core.

After a long period of work, the diaphragm is prone to fatigue, oxidation, etc., resulting in the appearance that the pressure relief port for a long time to vent, pulse valve does not work, the treatment is to replace the diaphragm.

The throttle orifice is blocked or damaged, and the inlet air is not clean, which will easily lead to the throttle orifice blocking. The appearance is that the pulse valve has been blowing air to the nozzle for a long time, and the treatment is to clean the throttle orifice. The damage or loss of the throttle orifice makes the throttle orifice lose its interception function, resulting in abnormal pressure relief. The appearance is that the pulse valve ACTS after receiving electricity, and the pressure relief orifice releases air, but the pulse valve does not spray, and the treatment mode is to replace the throttle orifice.

Electromagnetic pulse valve diaphragm operation

Pulse valve diaphragm, is the electromagnetic pulse valve air switch, electromagnetic pulse valve diaphragm back control pressure gas quickly discharged. Diaphragm front control pressure gas will lift the diaphragm, open the electromagnetic pulse valve channel into the bit on the injection, the electrical signal disappears, the electromagnetic pilot head of the spring to make the moving column immediately

Position closed unloading hole. Electromagnetic pulse valve diaphragm rear control gas pressure and spring force make the diaphragm close the channel, electromagnetic pulse valve stop blowing resistance hole on the diaphragm, when the pilot head moving column lift, gas pressure unloading, electromagnetic pulse valve diaphragm plays the role of resistance airflow, when unloading

When the load is closed, the pressure gas is quickly filled to the back chamber, which makes the electromagnetic pulse valve diaphragm close the channel and stop spraying.

Structure performance
Composed of one or more layers of two sides coated with glue, and also of rubber without fabric clip. According to the shape of the separation method membrane pressure

method. According to the requirements of the production of different rubber, different fabric diaphragm. The properties of nitrile rubber and polysulfide rubber blends used

in the diaphragm, the properties of rubber materials used in the canvas disc diaphragm and some silicone rubber, fluoro rubber and chloro rubber membranes developed in recent

years are described as follows.

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, aging

resistance, and the service life is equal to that of engine overhaul.
