Fast cutting characteristics of pneumatic valve and application are introduced

fast cutting characteristics of pneumatic valve products usage and selection guidelines
quickly cut off the pneumatic valve is a kind of automation system of actuators, pneumatic diaphragm actuator or by a more spring floating and regulating pneumatic valve piston executing agency, receive signals adjusting instruments, fluid control technology of the pipe on the cut, or switch. It has a simple structure, sensitive reaction, reliable operation, etc. They are widely used in coal gas, natural gas and liquefied petroleum gas and other combustible gases.

quickly cut off the purpose of the pneumatic valve
( ） Connected to combustible gas leakage monitoring instrument, when testing instruments to combustible gas leakage, automatically shut down the main gas supply pneumatic valves, cut off the gas supply, to prevent malignant accidents in a timely manner.
( ） With extreme temperature and pressure of heating equipment safety controller connection, when the temperature of the equipment within the testing point pressure exceeds the limit of the set value, pneumatic valve automatically shut down the gas supply, stop the supply of fuel.
( ） And the high-rise building fire alarm system in the middle of the connection, when building fire, cut off the gas inside the building, to prevent the occurrence of gas explosion.
( ） Within the gas supply network in the city or factory Settings, can be in the central control room centralized control, remote control quickly close the scene of the accident of pipeline gas supply.

fast cutting characteristics of pneumatic valve
quick to cut off the pneumatic valve is normally open type pulse trigger type solenoid pneumatic valve. Quick to cut off the pneumatic valve structure simple, responsive, reliable operation, accident characteristics of self-locking and manual reset function has been used in all walks of life. Mainly concentrated in the following aspects:
and pneumatic valve in daily work in a normally open state, electromagnetic solenoid coil is in power position, don't waste electricity.
and when the accident happened, coil instantaneous electric pneumatic valve, pneumatic valve quickly trigger closed, the state of self-lock. Right now even removed the power supply, pneumatic valve is still in the state of self-locking, does not automatically open again.
pneumatic valve, pneumatic valve adopts the forerunner type, open easily, even pressure to open the bar is also very easy, diameter greater than the DN, adopts the lever handle, pneumatic valve, a switch and effort.

quickly cut off the technical parameters of the pneumatic valve

quickly cut off the pneumatic valve information
place an order, if users have special request for products, must be in order to provide the following details: A length, structure, connection form B C, nominal diameter, full size, reducing, pipe size D E, using medium and temperature, pressure range, test, inspection standards and other requirements.
, such as provided by the user to determine pneumatic valve type and model, the client shall correctly explain the meaning of the model and requirements, under the condition of supply and demand both sides understand consistent sign the contract. According to the specific requirements of customers all kinds of electric, pneumatic, hydraulic, electromagnetic dynamic drive.
users, futures, order please confirm detailed told the pneumatic valve figure number, specification, quantity, place and time of delivery.

to cut off the pneumatic valve - quickly China pump pneumatic valve network quality manufacturers recommend:
