Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
A kind of in-line solenoid valve, as shown in Figure 1, it is by valve body 1, filling block 2, and dynamic iron core 3, concentrating flux plate 4, wire bushing 5, spring 6, coil 7, divided magnetic ring 8, static iron core 9, coil trim 10, tracheae fixed block 11, filter screen 12, coil rack 13 is installed successively and formed.
Wherein be provided with pore in a kind of valve body of embodiment, use as air outlet hole; In order to simplified structure, directly on static iron core, have pore, pore in static iron core is that inlet hole uses, the valve pocket holding dynamic iron core is provided with in valve body, coil winding is on coil rack, and static iron core is fixedly connected with coil rack, and coil outer is provided with coil trim, filling block is fixedly connected with dynamic iron core, dynamic connected by spring between iron core and static iron core.Wherein, filling block is as plug, and its effect is along with dynamic iron core moves together, blocks the pore in valve body, cuts off gas circuit.
The center of dynamic iron core is provided with spring chamber, and the pore in this spring chamber and valve body, the pore in static iron core form main gas circuit jointly.Block for filled piece bottom the spring chamber of dynamic iron core, filling block upper end is provided with spring, the other end of this spring withstands the bottom of static iron core, and have in dynamic iron core outer installment the vent slot communicated with the valve pocket in valve body, this vent slot is communicated by the aperture on spring chamber inwall with the spring chamber in dynamic iron core.
As shown in Figure 3, vent slot is distributed on the outer wall of dynamic iron core, and every bar vent slot all has aperture to communicate with spring chamber inside.
The bottom of described static iron core, is embedded with divided magnetic ring, and divided magnetic ring is fine copper manufacture.
The bottom of coil trim is provided with concentrating flux plate.Concentrating flux plate encapsulated coil case, prevents foreign matter from entering in coil, and contributes to the concentration magnetic line of force, strengthens coil magnetic field to the attraction force of dynamic iron core.
Filling block is that rubber is made, and is arranged on the inside of dynamic iron core, and its top and the bottom of spring offset, and its bottom is connected with the pore on valve body.Pore end bottom valve pocket, the position contacted with filling block is provided with type conical bench.This step, when filling block blocks the pore of valve body, produces certain distortion to filling block, concentrates near the outlet of pore by the pressure that spring transmission comes, and improves sealing.
The lighting outlet of described coil, is provided with wire bushing protection.
From cost-saving and angle that is manufacturing process, the present invention is directly at the outer installment tracheae fixed block of the outside of valve body and static iron core.In the present invention, valve body also arranges separately suction port and air outlet in addition.
Its working procedure as depicted in figs. 1 and 2, high pressure air enters from the top of static iron core, enter in valve pocket by the pore in static iron core, and the bottom of the valve pocket that gone directly by the vent slot be distributed on dynamic iron core outer wall, now be not energized, coil produces without magnetic field, and under the thrust of spring, dynamic iron core moves down, and filling block blocks the outlet of valve body inner air vent.
If coil electricity, produce magnetic field, dynamic iron core is magnetically attracted, and upwards pulls, separately the outlet of filling block and valve body.Now dynamic iron core moves, the dynamic upper surface of iron core contacts with the divided magnetic ring of the lower surface of static iron core, original dynamic gap between iron core and static iron core disappears, high pressure air now in interior static iron core, by the through hole in dynamic iron core upper spring chamber, continuation and vent slot communicate, solenoid valve is opened completely, high pressure draught by the pore of static iron core, spring chamber, through hole, the vent slot of dynamic iron core, enters bottom valve pocket, and discharges from the pore in valve body successively.
If coil blackout, then magnetic field dissipate, filling block is promoted descending by spring, again block the pore of valve body.
The tracheae fixed block of embodiment one have employed male connection, and the tracheae fixed block of embodiment two have employed female adapter, and the tracheae fixed block of embodiment three have employed spigot joint.
As shown in the figure, embodiment four to embodiment six also have employed above-mentioned three kinds of fit systems respectively.With first three plant embodiment unlike, its working method that have employed reverse gas circuit, air inlet is positioned at the pore of valve body, and air outlet is the pore of static iron core.
Because air inlet acts directly on the bottom of filling block, have the trend promoting filling block and move upward, in order to realize sealing effect, the spring force that the spring force of this type of solenoid valve is arranged on static iron core than air inlet is larger.
The central shaft of the gas circuit such as suction port, air outlet and coil keeps point-blank by the utility model, this structure farthest can reduce the radial dimension of solenoid valve, and be convenient to be directly installed in gas circuit, its compact is convenient to install, and is particularly suitable for the occasion of gas circuit transformation.
