Abstract
The utility model discloses a mini-solenoid valve. The mini-solenoid valve comprises a pilot valve, a gas circuit control main valve and a sealing combination ring which is arranged on a valve rod inside the gas circuit control main valve, wherein a movable iron core assembly and a static iron core assembly are arranged at the inner portion of the pilot valve, a locking nut is arranged on the static iron core assembly of the end portion of the pilot valve, the pilot valve is fixed on the gas circuit control main valve through the locking nut, and a ZD model is adopted by the sealing combination ring. The mini-solenoid valve overcomes the defect that the installation angle of the existing pilot valve of the mini-solenoid valve is incapable of being adjusted. Therefore, the mini-solenoid valve has the advantages of being convenient to install, good in sealing effect, steady in working condition and the like.

The model utility content
The technical problem that the utility model solves has provided a kind of miniature electromagnetic valve, and the electromagnetic priority valve of this model utility can satisfy the different amount installation requirement, and is corrosion-resistant, ageing resistance is strong, and good sealing effect is applicable to work under the high and low temperature environment.
For solving the problems of the technologies described above, the utility model miniature electromagnetic valve, comprise pilot valve, gas circuit control main valve and be arranged on seal combination circle on the valve rod in the gas circuit control main valve, described pilot valve inside is provided with moving core assembly and static iron core assembly, the static iron core assembly of described pilot valve end is provided with locking nut, described pilot valve can be done 360 degree rotations, and pilot valve is fixed on the gas circuit control main valve by locking nut, and described seal combination circle adopts the seal combination circle of ZD model.
Described gas circuit control main valve comprises valve seat, main valve and the end cap that resets, the valve seat control chamber is established in described valve seat inside, control piston is established in the inside of valve seat control chamber, the inside of described main valve is provided with the main valve control chamber, establish valve rod in the main valve control chamber, an end of described valve rod connects control piston, and the other end is connected in the Returnning spring of the end cap inside that resets, also be provided with some gas circuit inverting chambers on the described main valve, communicate with main valve control chamber inside respectively.The beneficial effects of the utility model:
1, adopts 360 degree rotary type pilot valves, can adjust flexibly the setting angle of pilot valve according to the requirement of using, thereby satisfy the user for the user demand of the different setting angles of pilot valve.
2, adopt ZD type seal combination circle, this seal combination circle is corrosion-resistant, the aging-resistant performance is stronger, long service life, be applicable to work under the high and low temperature environment, so that the sealing effect of whole miniature electromagnetic valve is better, working condition is more stable, can effectively avoid the generation of gas leak phenomenon.
The utility model miniature electromagnetic valve has overcome the deficiency that the pilot valve of existing miniature electromagnetic valve can not be according to requirements adjusted setting angle.The pilot valve of the utility model miniature electromagnetic valve can carry out 360 setting angle adjustment, have install easy to adjust, good sealing effect, the characteristics such as working condition is stable.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model miniature electromagnetic valve overall structure schematic representation;
Among the figure: 1-pilot valve, 2-gas circuit control main valve, 3-locking nut, 4-valve seat, 5-main valve, 6-reset end cap, 7-valve seat control chamber, 8-control piston, 9-main valve control chamber, 10-valve rod, 11-seal combination circle, 12-Returnning spring, 13-gas circuit inverting chamber, the moving core assembly of 14-, 15-static iron core assembly, 16-valve seat mouthpiece.
Embodiment
As shown in Figure 1, the utility model miniature electromagnetic valve, comprise pilot valve 1, gas circuit control main valve 2 and be arranged on seal combination circle 11 on the valve rod 10 in the gas circuit control main valve 2, described pilot valve 1 inside is provided with moving core assembly 14 and static iron core assembly 15, the static iron core assembly 15 of described pilot valve 1 end is provided with locking nut 3, described pilot valve 1 can be done 360 degree rotations, pilot valve 1 is fixed on the gas circuit control main valve 2 by locking nut 3, and described seal combination circle 11 adopts the seal combination circle of ZD model.These seal combination circle 11 good sealing effects, corrosion-resistant, anti-aging, can under high and low temperature environment, work, working condition is more stable.
When pilot valve 1 setting angle was adjusted, then first rotational lock nut 3 adjusted pilot valve 1 setting angle so that pilot valve 1 is loosening, adjusts after the angle, tightened locking nut 3 with fixing.
Described gas circuit control main valve 2 comprises valve seat 4, main valve 5 and the end cap 6 that resets, valve seat control chamber 7 is established in described valve seat 4 inside, control piston 8 is established in the inside of valve seat control chamber 7, the inside of described main valve 5 is provided with main valve control chamber 9, establish valve rod 10 in the main valve control chamber 9, one end of described valve rod 10 connects control piston 8, the other end is connected in the Returnning spring 12 of end cap 6 inside that reset, also be provided with some gas circuit inverting chambers 13 on the described main valve 5, one end of gas circuit inverting chamber 13 is the external module connecting end, and the other end communicates with main valve control chamber 9 inside.
Moving core assembly 14 can move under electromagnetic force vertically, and moving core assembly 14 forms sealing configuration with the valve seat mouthpiece 16 that valve seat 4 inside are provided with.
During work, behind the coil electricity in the pilot valve 1, moving core assembly 14 adhesive under the effect of electromagnetic force in the pilot valve 1, the control gas circuit is opened, air pressure enters valve seat control chamber 7 through valve seat mouthpiece 16, gas in the valve seat control chamber 7 acts on control piston 8, and control piston 8 related valve rods 10 are moved together, and valve rod 10 moves and switches main valve 5 interior gas circuit flow directions.When in the pilot valve during 1 coil blackout, moving core assembly 14 sets back under the elastic force effect, valve seat mouthpiece 16 is sealed, main valve control chamber 9 is in exhaust condition, valve rod 10 sets back under the effect of Returnning spring 12 and main valve control chamber 9 interior residual air, thereby finishes a commutation actuation cycle of valve rod 10.
