Gas solenoid pneumatic valve structure principle and installation and maintenance instructions

gas solenoid pneumatic valve is suitable for city gas, liquefied petroleum gas, natural gas and other gas pipeline, make two type on-off switch for automatic control of actuators. It is widely used in textile, dyeing of gas heat styling, bulb and glass kiln heating gas heating control system and other industries.
gas solenoid pneumatic valve structure principle
gas solenoid pneumatic valve has simple structure, large flow, long life, safe and reliable, etc.
this pneumatic valves direct-acting type low voltage solenoid pneumatic valve. On-off control medium of pneumatic valve seal mouth, through the pneumatic valve rod directly connected to the core activity.
DN diameter above the gas solenoid pneumatic valve, should adopt the secondary structure of pneumatic valve open.
depending on the power of switch state can be divided into pneumatic valve and normally open normally closed electromagnetic solenoid pneumatic valve, pneumatic valve, normally closed electromagnetic power, often by weight of armature and seal spring and medium pressure pneumatic valve mouth sealed, cutting off is accused of medium flow.
gas solenoid pneumatic valve working principle of the electromagnetic coil after electrify,
electromagnetic pneumatic valve to overcome the armature self-respect and seal spring core, medium pressure forces will activities, together with the pneumatic valve gasket on the suction mouth, open the pneumatic valve mouth, was charged with medium negotiable.
power normally open solenoid pneumatic valve, electromagnetic suction is equal to zero, in the spring under the action of moving iron core, pneumatic valve lever up and, pneumatic valve is opened, medium circulation. When electricity due to the suction effect moving iron core down, promote the pneumatic valve stem, pneumatic valve closed, medium is broken.
gas solenoid pneumatic valve work
general circulation coefficient is very small, and the work pressure difference is very small. Such as average diameter than the diameter of the solenoid pneumatic valve flow coefficient of the electric pneumatic valve ball. Electromagnetic pneumatic valve driven by electromagnetic coil, more easily damaged by voltage surge. Equivalent to the role of the switch is on or off a role.
gas solenoid pneumatic valve installation instructions
, when installation, electromagnetic solenoid coil up, and keep the vertical position, the arrow or mark in the solenoid pneumatic valve should be consistent with the pipe flow, shall not be installed in places with splashing water or water leakage.
the working medium of pneumatic valve, electromagnetic should be clean and no impurity particles, electromagnetic pneumatic trims on the surface of the dirt and filters, need to clean on a regular basis.
failure occurs, the electromagnetic pneumatic valve, in order to timely isolation solenoid pneumatic valve, and ensure the normal operation of the system, the best install bypass device.
, in the pipeline system, installed on the branch of the solenoid pneumatic valve size should be less than the main sizes of pneumatic valve.
, before install solenoid pneumatic valve, pipe must be clean. Installation of the filter in front of the solenoid pneumatic valve is recommended, hydrophobic pneumatic valve steam pipeline installation.
and solenoid pneumatic valve can not be installed in the pipeline dips, lest because of steam condensation water, impurities, such as the precipitation in the pneumatic valve and hamper the action.
and normal solenoid pneumatic valve cannot be used in explosion hazard.
, under the condition of insufficient rigidity pipeline, recommend to use before the solenoid pneumatic valve pipe bracket, so as to avoid electromagnetic vibration caused by pneumatic valve work.
and before install solenoid pneumatic valve, electromagnetic pneumatic valve should pay attention to see the product sign, read the instruction manual, pneumatic valve whether solenoid pneumatic valve products comply with the conditions of use.
, electromagnetic pneumatic valve should be installed on the pipeline before and after the pressure gauge, in order to observe the pipe pressure.
7, gas solenoid pneumatic valve use maintenance
hold people accountable for use and maintenance, recommend the use of units.
, electromagnetic pneumatic valve is installed to access into the medium experiment several times, confirmed rear can put into normal use.
and should be cleaned regularly on the pneumatic valve inside and outside and bit off the dirt, be careful not to damage the sealing surface.
pneumatic valve, electromagnetic, when not in use for a long time to close the pneumatic valve pneumatic valve, manual restart, solenoid pneumatic valve of steam condensed water should be ruled out clean, and try several times, to switch to normal rear can put into use.
pneumatic valve, electromagnetic need not when, from the internal parts shall be stored wiping clean with compressed air blowing off.
, use for a long time, such as between piston and pneumatic valve seat seal, piston sealing surface can be smooth again, and pneumatic valve seat grinding.
, at work, must pay attention to the pneumatic valve and pressure gauge, the required working pressure shall not exceed the rated pressure, working pressure difference must be within the rated pressure difference. When working pressure over the rated pressure or differential pressure over the rated pressure difference, to stop using pneumatic valve, pneumatic valve manually, before and after closing to avoid electromagnetic pneumatic valve explosion and leakage.
