Pneumatic stainless steel valve manufacturers across the shallow of all standing valve solenoid valve at home and abroad, so far, the classification of the electromagnetic valve is as follows: from the movement style can be divided into three categories: direct acting, recoil type, the forerunner, from disc structure and material of different and the difference on the principle of recoil type can be divided into: diaphragm recoil electromagnetic valve, electromagnetic valve piston recoil; Guiding type can be divided into: pilot operated diaphragm solenoid valve, the guide piston solenoid valve; From the seat and the sealing material points can be divided into: soft seal solenoid valve, electromagnetic valve seal rigidity, semi-rigid sealed electromagnetic valve. A, direct acting solenoid valve principle: direct acting solenoid valve normally closed type electric hair pavilion to join in, when the electromagnetic coil electromagnetic suction lift valve core, make close thing away open seat seal open; Power, the electromagnetic force, by the spring force closure member pressure on the valve seat valve closed. ( Normally open type to the contrary) Characteristics: in a vacuum, negative pressure, can work properly when the zero pressure difference, (the following can be installed arbitrarily, but electric magnetic head larger. Such as my company introduction of HERION technology production of direct acting solenoid valve can be used for 1. 33×10- 4 Mpa vacuum. Recoil type solenoid valve principle: the principle of it is a direct acting and pilot, the combination of power, the electromagnetic valve and auxiliary valve first opened, the main valve cavity pressure on inferior vena pressure is greater than the exercise of differential pressure and solenoid valve open valve function at the same time; Power, the exercise auxiliary valve spring force or medium pressure push off, move down the valve closed. Feature: when in zero pressure difference or high pressure can also be reliable work, but the power and volume is larger, for vertical installation. Second, the principle guiding type electromagnetic Industrial Valves: electricity, the electromagnetic drive pilot Industrial Valves to open the pilot valve, the main valve cavity pressure on agile landing, formed in the inferior vena differential pressure on the main valve, pressure on medium to promote the main valve shut up, open valve. When power off, the pilot Industrial Valves spring force closed cab delong keyword optimization, medium entrance pressure through the forerunner Kong Minjie into the main valve cavity formed in the cavity pressure difference, thus makes the main valve to close. Features: small volume, low power, but the limited scope of medium pressure difference, must be content with differential pressure conditions. Two of the 3-way magnet valve (usually with single-acting pneumatic implementing agencies, two is two position control: open - Pass, three links, there are three channels ventilation as usual case 1 channel connected with gas source, the other two channel 1 and implement organization inlet connection, a vent connection with practice institutions, detailed working principle can consult single-acting pneumatic implementing agencies working principle diagram. Two five-way solenoid valve two five-way solenoid valve which is equipped with double-acting pneumatic implementing agencies, two is two position control: open - , there are five tunnel ventilation, 45 is one connected with gas source, two external and double-acting cylinder chamber in and out of the port connection, two with the internal chamber in and out of the port in succession, you may refer to detailed working principle of the double-acting pneumatic implementing agencies working principle of the principle that energized the website price, the electromagnetic drive pilot valve to open the pilot valve, the main valve cavity pressure on agile landing, formed in the inferior vena differential pressure on the main valve, pressure on medium to promote the main valve shut up, open valve; Power outages, the pilot valve is shut, spring force medium entrance pressure through the forerunner Kong Minjie into the main valve cavity formed in the cavity pressure difference, so that the main valve to close. Features: small volume, low power, but the limited scope of medium pressure difference, must be content with differential pressure conditions. Two of the 3-way magnet valve (usually with single-acting pneumatic implementing agencies, two is two position control: open - Pass, three links, there are three channels ventilation as usual case 1 channel connected with gas source, the other two channel 1 and implement organization inlet connection, a vent connection with practice institutions, detailed working principle can consult single-acting pneumatic implementing agencies working principle diagram. Two five-way solenoid valve two five-way solenoid valve which is equipped with double-acting pneumatic implementing agencies, two is two position control: open - Pass, there are five tunnel ventilation, 45 is one connected with gas source, two external and double-acting cylinder chamber in and out of the port connection, two with the internal chamber in and out of the port in succession, you may refer to detailed working principle of the double-acting pneumatic implementing agencies working principle in the gas path ( Or hydraulic) Two, the 3-way magnet valve (with one air inlet ( Answer the intake air) And 1 air flow ( Should provide the destination air) , a vent ( Install a silencer as usual, if afraid of noise can also not stored @ _ @) 。 Two five-way solenoid valve with one air inlet ( Answer the intake air) And 1 is action air flow and a reactionary porosity ( Should target respectively provided a is a reverse action of air) And 1 is motion vents and a reverse action vent ( Install the muffler) 。 As usual for small active control devices, trachea chooses 8 ~ 12 mm industrial adhesive trachea.
