Description
Technical field
The utility model relates to a kind of solenoid valve, especially the solenoid valve that uses on the energy-saving lamp exhausting car.
Background technique
Exhaust, be one procedure in the power saving fluorescent lamps production process towards the argon operation, purpose is the air in the fluorescent tube to be extracted clean, charges into the argon gas that can prevent the filament oxidation then in fluorescent tube.In order to guarantee the effect of bleeding, be equipped with many solenoid valves that the opening and closing gas pipeline is used that are used on the vacuum equipment.The structure of this class solenoid valve is that the moving direction of spool becomes plumbness with the interior gas pipeline of valve, utilizes the spool moving linearly in the magnetically actuated valve, and perhaps roof pressure covers the ventilation valve port, perhaps leaves the ventilation valve port, thereby opens or close gas pipeline.The deficiency of this valve is that the sealing of valve body is tight inadequately, and leakage point is too much, has reduced the effect of bleeding of fluorescent tube thus, and the fluorescent tube quality is also impacted.
The model utility content
The purpose of this utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of solenoid valve is provided, and this solenoid valve should have reliable operation, dead-tight characteristics.
The technological scheme that the utility model proposes is: vertical Through solenoid valve comprises the valve body of rotary structure being shaped on the cavity as air-flow path in the valve body that the valve body two ends are respectively arranged with suction port and the air outlet that communicates with described cavity; It is characterized in that being shaped on the shoulder hole coaxial with valve axis in the described cavity, in-line is being arranged spool, push rod and the armature that is in contact with one another in regular turn and all can slides along valve axis in the shoulder hole, and the periphery of armature is being provided with coil; One end of valve body upper valve core is made the taper shape that matches with the shoulder hole port and is opened or the valve port of closed gas flow passage to form, so that behind coil electricity, produce magnetic force toward front wheel driving armature, and by push rod roof pressure spool close port; Also have a spring to force in valve body and shoulder hole port respectively in the cavity, so that the pushing spool is opened valve port after magnetic force disappears.
The circumferential surface of described spool is shaped on several grooves parallel with valve core axis, is beneficial to airflow.
The circumferential surface of described armature is shaped on the groove of several and armature shaft line parallel, is beneficial to airflow.
Described shoulder hole port is provided with seal ring.
The junction at described valve body middle part is provided with seal ring.
The junction welded seal at described valve body middle part.
Working principle of the present utility model is: produce magnetic force behind the coil electricity toward front wheel driving armature, and promote spool by push rod and overcome the spring force motion, thereby and with the spool roof pressure in shoulder hole port close port, cut off air-flow path; Magnetic force disappears behind the coil losing electricity, opens valve port thereby spring just pushes away spool the shoulder hole port, and air-flow path is unimpeded immediately.
The beneficial effects of the utility model are: because the line of motion of spool is coaxial with valve body, thereby whole valve body can accomplish that sealing tightly, can not leak gas; The working efficiency that this has not only significantly promoted vacuum equipment has reduced energy consumption; And can significantly improve the vacuum pressure of vacuum equipment, and then the residual gas after making fluorescent tube bleed is still less, the end product quality of fluorescent tube is improved, and also prolonged working life.

Fig. 1 is a main TV structure schematic representation of the present utility model.
Fig. 2 is the cross sectional representation of the spool in the utility model.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.
Vertical Through solenoid valve, the valve body (forming after being tightened by screw thread 3-1 by front valve shell 9 and rear valve body 3 as can be known among the figure) that comprises rotary structure, be shaped on the cavity of air-flow path in the valve body, the valve body two ends are respectively arranged with suction port 12 and the air outlet 1 that communicates with described cavity; Be shaped on the shoulder hole coaxial in the described cavity with valve axis, in-line is being arranged spool 8, push rod 7 and armature 4 in the shoulder hole, spool 8, push rod 7 and armature 4 are in contact with one another in regular turn, and can slide all that (as seen from the figure, spool 8 directly slides with push rod 7 in the slide opening of front valve shell 9 along the slide opening in the cavity along valve axis; Armature 4 then with the coaxial sliding sleeve 2 of valve body in slide); The periphery of armature is being provided with coil, and the magnetic force that produces behind the coil electricity directly produces driving force to armature.One end of spool (towards an end of suction port) is made the taper shape that matches with the shoulder hole port 9-1 connecting part of aperture (macropore with), opens or the valve port of closed gas flow passage to form; Like this, coil electricity rear driving armature and by push rod roof pressure spool (overcoming spring force) energy close port just; Also have a spring 10 application of force and valve body and shoulder hole port respectively in the cavity, magnetic force disappearance rear spring just can push spool and then open valve port.
The circumferential surface of described spool 8 is shaped on several groove 8-2s parallel with valve core axis, is beneficial to airflow; Equally, the circumferential surface of described armature 4 also is shaped on the groove of several and armature shaft line parallel, is beneficial to airflow.
Sealing effect when improving the closing of valve port, described shoulder hole port is provided with seal ring 11.
For improving the integral sealing effect of valve body, the junction (junction between front valve shell 9 and the rear valve body 3) at described valve body middle part is provided with seal ring 6; Perhaps welded seal is adopted in this junction.
