Embodiment
Pilot solenoid valve structure is divided into pilot section and primary valve part by the present invention, and pilot section is suction-type magnetic valve,
Primary valve part is Air control valve.Pilot section employs metal to nonmetallic hard soft seal knot with primary valve part sealing pair
Structure, metal material are stainless steel, and nonmetallic materials are rubber.Pilot section inner chamber connects with primary valve part inner chamber.When not powered,
Due to the piston of primary valve part and the difference in areas of valve element, piston is pressed onto pilot section side, main valve by primary valve part intracavitary air pressure
Partial valve port is closed；After power-up, pilot section is opened, and gases at high pressure enter on the left of piston, by piston pressure
To right side so that the valve port of primary valve part is in open mode.
As shown in figure 1, being the structural representation of pilot solenoid valve of the present invention, pilot section mainly includes guide valve blocks 1, elder generation
Pilot valve spring 2, coil 3, outer magnetizer 4, pilot valve armature 5, poppet port seal 6, guide's valve base 7, primary valve part master
It is close including regulation damping 8, O-ring seal 9, piston 10, main spool spring 11, valve body of main valve 12, main valve mouthful seal 13, port
Seal 14, valve core of main valve 15, end cap 16.Wherein poppet port seal 6, O-ring seal 9, main valve mouthful seal 13, port are close
Seal 14 is elastomeric material, and other parts are metal material.Poppet port seal 6 passes through vulcanization, hot pressing or other machines
Tool connected mode is fixed on pilot valve armature 5.
When primary valve part is installed, O-ring seal 9 is fitted into two annular grooves of piston 10, while adjusts damping 8 and screw in piston
In the screwed hole of 10 end faces.Piston 10 is fitted into guide's valve base 7.The external diameter of guide's valve base 7 is tapped, passes through screw thread pair
It is fixed together with valve body of main valve 12.
As shown in Fig. 2 being provided with groove on guide's valve base 7, the inner chamber of pilot section is connected with the inner chamber of primary valve part.
Main spool spring 11 is fitted into the hole of valve body of main valve 12, the piston 10 equipped with sealing ring 9 and regulation damping 8 is then screwed in into main valve
In valve body 12.Main valve mouthful seal 13 and port sealing circle 14 are fitted into valve core of main valve 15, then screwed in valve core of main valve 15
In the right side screw thread of piston 10.End cap 16 is finally installed.The structure of valve core of main valve 15 is as shown in Figure 3.Pay attention to ensureing piston during installation
Gap between 10 left sides and guide's valve base 7, that is, control the cavity volume in the left side of piston 10.Cavity volume volume increases, then first conductive magnetism
Valve is opened and the time of release can extend.
Electromagnetic valve entrance is located on valve body of main valve 12, and electromagnetic valve outlet is located on end cap 16.
Guide valve blocks 1 are inserted in outer magnetizer 4 by pilot section first when installing.Then guide's valve spring 2 is loaded into guide
In valve armature 5, then pilot valve armature 5 is fitted into guide valve blocks 1.
Pilot section and primary valve part are then formed into complete valve using welding or thread connecting mode.
In a non-operative state, there is no electric current in coil 3, pilot section is in closed mode with primary valve part.Guide
Poppet port seal 6 is pressed on the valve port of guide's valve base 7 by part, spring 2 and pressure medium, forms guide's sealing pair.
Main valve mouthful seal 13 is squeezed on valve body of main valve 12 by primary valve part, valve core of main valve 15, forms primary seal pair.And primary seal pair
Effective diameter be less than the left end diameter of piston 10, i.e., under pressure medium effect, piston 10 is suffered to make a concerted effort to the left, to be advantageous to lead close
Seal secondary closing.
Part guide valve base 7 has three effects：1) valve seat as pilot valve, formed with poppet port seal 6
Sealing pair；2) dynamic sealing pair is formed with O-ring seal 9, piston 10；3) external diameter is slotted, connection entrance, main valve inner chamber and pilot valve
Medium in inner chamber.
Under working condition, after coil 3, which powers up, to be opened, the electromagnetic force that armature 5 is subject to overcomes the spring force and medium of spring 2
Pressure sum, poppet port seal 6 separates with the valve port of guide's valve base 7, and medium enters guide's valve base 7 and piston 10
Between cavity volume, it is established that pressure, open primary valve part；After 3 dead electricity of coil, the electromagnetic force that armature 5 is subject to is gradually reduced,
When the spring force of spring 2 is more than electromagnetic force, armature 5 moves to guide's valve base 7, poppet port seal 6 and pilot valve valve
The valve port fitting of seat 7, forms guide's sealing pair.Now, the power that guide's sealing pair is subject to is the spring force and pressure medium of spring 2
Sum.The medium in cavity volume between guide's valve base 7 and piston 10 is gradually let out by adjusting the centre bore of damping 8 and piston 10
Pressure, primary valve part are closed under spring force and pressure medium effect.
The aperture of regulation damping 8 has a dimension series, by adjusting the size of aperture, can adjust guide's valve base
Cavity volume between 7 and piston 10 builds the speed of pressure, and then adjusts the opening speed of primary valve part.If the aperture of regulation damping 8
Diminish, after pilot solenoid valve, which powers up, to be opened, the voltage built-up rate in the left side of piston 10 can be accelerated, so as to the opening speed of primary valve part
Also can accelerate.However, after the aperture of regulation damping 8 diminishes, after pilot solenoid valve is closed, the pressure release speed of the left side cavity volume of piston 10
Degree also can be slack-off, also can be slack-off so as to the closing velocity of primary valve part.I.e. when the aperture of regulation damping 8 becomes small, primary valve part
Opening speed accelerates, and closing velocity is slack-off；Conversely, when the aperture of regulation damping 8 becomes big, primary valve part opening speed is slack-off,
Closing velocity accelerates.
During the response of the aperture of joint control and regulation damping 8 and the volume can control valve of the left side cavity volume of piston 10
Between.
The course of work of the present invention is as follows：
The not powered state of pilot solenoid valve：
Guide's sealing pair keeps sealing, the cavity between guide's valve base 7 and piston 10 and primary valve part outlet, no
Pressure medium be present.
Valve core of main valve 15 is connected by screw thread with piston 10.The left end diameter of piston 10 (shown in Fig. 1) is more than valve core of main valve
15 diameter, i.e. medium power act on piston 10, make a concerted effort F1 directions to the left on 15 two parts of valve core of main valve, and main spool spring
11 are in compressive state, have spring force f1.Thus at the time of pilot section is not powered, main valve sealing pair remains turned-off shape
State.
Pilot solenoid valve opening process：
Due to being provided with groove on guide's valve base 7, guide inner chamber is connected with main valve inner chamber.When guide's partial power on,
Poppet port seal 6 separates with guide's valve base 7, and medium flows into main valve inner chamber by entrance, then via guide's valve base 7 outside
The groove of wall, guide inner chamber is flowed into, and then by the centre bore of guide's valve base 7, flowed between guide's valve base 7 and piston 10
Cavity.Because the aperture of guide's valve base 7 is more than the aperture of regulation damping 8, the left side cavity of piston 10, which is known from experience, establishes pressure, pressure
The aperture relation that numerical value is damped 8 two parts by guide's valve base 7, regulation determines.Guide's valve base 7 and the hole of regulation damping 8
Footpath ratio is bigger, and the pressure of the left side cavity of piston 10 is higher, closer to inlet pressure.The pressure medium F2 of the left side cavity of piston 10
To the right, and more than main valve closed mode the F1+f1 that makes a concerted effort in left side is pointed to, opens main valve sealing pair.Medium flows into from entrance, warp
Flowed out by main valve sealing pair opening.And during piston 10 moves right, all the time with F2 '>F1 '+f1 ' F2 ', F1 ',
F1 ' is respectively the medium power and spring force during piston 10 moves right.End cap 16 works as piston to the sports limiting of piston 10
10 move right, and when valve core of main valve 15 contacts with end cap 16, piston 10 moves to extreme position.Valve core of main valve 15 is close to end cap 16
Side, 4 fan grooves are provided with, as fluid passage.
Pilot solenoid valve closing process：
After pilot section dead electricity, guide's sealing pair is closed.The medium of entrance can not go successively to guide's valve base 7 with living
Cavity between plug 10, the medium in this cavity gradually flow to outlet, thus guide's valve base 7 by adjusting the aperture of damping 8
The pressure in cavity between piston 10 gradually reduces.When cavity internal pressure, to act on piston 10 F2 ' that makes a concerted effort to the right small
When main valve closed mode to the left make a concerted effort F1 '+f1 ' when, main valve sealing pair close, medium can not from main valve seal vice division chief continue
Outflow.
The content not being described in detail in description of the invention belongs to the known technology of those skilled in the art.
