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.
