The electromagnetic characteristics and purposes of pneumatic valve of steam

to steam solenoid pneumatic valve applicable scope on steam for heating medium, automatic temperature control of actuators. For steam heater, radiator, dryer steam equipment and all kinds of temperature control instrument, such as steam setting machine, dyeing machine, damping machine such as complete sets of equipment of boiler steam pipelines for two type automatic control and remote control. Widely used in dyeing, textile, printing and dyeing, food, medicine, cigarettes, cement products, petroleum chemical industry, metallurgy and other department of automatic control system.
steam solenoid pneumatic valve main characteristics are the following:
a, leakage blocking, internal leakage is easy to control, the use of safe. The elements of internal and external leakage is unsafe. Other control pneumatic valve pneumatic valve rod stretched out, and is usually controlled by the electric, pneumatic, hydraulic actuator pneumatic valve core rotation or movement. This will solve the long-term action of pneumatic valve lever dynamic seal leakage problem; Only solenoid pneumatic valve is applied to seal in the electric control pneumatic electric magnetic valve magnetic casing insulation core completion, there is no dynamic seal, so leakage blocking off easily. Electric pneumatic valve torque control is not easy, prone to leakage, even snap pneumatic valve stem head; Solenoid pneumatic valve structure is easy to control the internal leakage, until reduced to zero. So, solenoid pneumatic valve using a special security, especially suitable for corrosive, toxic, or high and low temperature medium.
2, steam solenoid pneumatic valve system is simple, and the computer, prices are low. Steam solenoid pneumatic valve itself structure is simple, the price is too low, compared to adjust the pneumatic valve and other kinds of actuators is easy to install and maintain. More significant is composed of automatic control system is much simpler, much lower prices. Because electromagnetic pneumatic valve is switch signal control, connection with industrial control computer is very convenient. In today's computers, prices plunged, steam solenoid pneumatic valve advantages are more obvious.
3, steam solenoid pneumatic valve action express, power is small, light shape. Solenoid pneumatic valve response time can be short as a few milliseconds, even the guiding type solenoid pneumatic valve can control in a few milliseconds. Because of its circuit, more sensitive than the other automatic control of pneumatic valve response. Properly designed electromagnetic solenoid coil power consumption is low, energy-saving products; Can also be simply trigger action, keep the pneumatic valve position automatically, no electricity at ordinary times. Steam solenoid pneumatic valve appearance size, save a space already, and light and beautiful.
4, regulating precision limited, limited suitable medium. Steam solenoid pneumatic valve usually only two state switch, pneumatic valve core is only in the two limit position, not continuous adjustment, Tries to break a lot of new conception, but also in the test trial stage) So the adjustment accuracy is limited.
steam solenoid pneumatic valve has higher requirements to the cleanliness of medium, medium containing granular not applicable, must be filter for impurities. In addition, a viscous medium not applicable, and shall be applicable to the specific products of medium viscosity range is relatively narrow.
5, steam solenoid pneumatic valve type diversity, wide range of USES. Steam solenoid pneumatic valve is congenitally deficient, the advantage is still outstanding, so he designed a variety of products, meet the needs of different, use very extensive. Steam solenoid pneumatic valve technology advances are also revolve around how to overcome the deficiency, how to better play to the inherent advantages.
steam solenoid pneumatic valve is wear-resisting, heat resistance, resistance to condensation.

currently used steam solenoid pneumatic valve, usually have the following two kinds of steam:
saturated steam boiler steam temperature and pressure is relatively stable, the temperature is lower than ℃, working pressure is below.
usually choose soft sealing steam solenoid pneumatic valve:
structure features: this pneumatic valve is made up of pair of pneumatic valve and the main two parts of the guide type pneumatic valve open secondary pneumatic valve solenoid pneumatic valve.
heat: electromagnetic, seal part with special high temperature resistant electric material and sealing material, and the application of all kinds of insulation measures.
: wear-resisting material selection is reasonable, the pneumatic valve and guidance suite skillfully use of fluid lubrication, reducing wear and tear, improve life
condensation resistance: steam condensation water is the important factors that affect steam solenoid pneumatic valve action, the pneumatic valve is not affected by the condensed water.
this series solenoid pneumatic valve can also be widely used for textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and scientific research departments and bathroom, dining room, air conditioning automatic control system, etc. , thermal power plant superheated steam temperature of the steam pressure change base is bigger,
temperature as high as above, work pressure is below.
will usually choose hard seal steam solenoid pneumatic valve:
structure features: using metal hard seal, increases the service life of the temperature and the use of the product.
select material is reasonable, the pneumatic valve and guidance suite skillfully use of fluid lubrication, in order to reduce wear and tear.
other USES hard seal steam solenoid pneumatic valve this product with wider range of general medium, can be used respectively in the water, light oil, heavy oil, non - corrosive gas and steam and other fluids. Suction pipe drain system such as power plants and the evaporator of the exhaust system, mainly for the medium in the pipeline two position automatic adjustment and remote control.
working status: normally closed type electric power on, power off normally open type open, the electricity shut.
