An axial self-locking mechanism is arranged between an iron core of the electromagnet and the valve core; the axial self-locking mechanism comprises a connecting bar which is arranged in the valve body and can not rotate; one end of the connecting bar is fixedly connected with the iron core while the other end thereof is provided with a blind hole; a ratchet mechanism is arranged in the blind hole and comprises an upper ratchet wheel and a lower ratchet wheel that are mutually meshed, and the lower ratchet wheel is fixedly connected with the connecting bar; a first return spring is pressed between the upper end of the upper ratchet wheel and the bottom surface of the blind hole; the lower end of the upper ratchet wheel is fixedly connected with the valve core; and a second return spring is pressed between the connecting bar and the top part of the valve body. The self-locking electromagnetic valve provided by the utility model adopts the mode of mutually meshed ratchet wheels to realize the axial self-locking of the valve core, and eliminates the circumstance that the declining elasticity of a spring leads to declining self-locking performance or even utterly invalid auto-lock function, thereby effectively improving the self-locking performance and prolonging the service life.
Description
Technical field
The utility model relates to a kind of self-locking electromagnetic valve, belongs to the solenoid valve technical field.
Background technique
To the economize on electricity of solenoid valve and the research that reduces magnetic interference is one of important topic of always studying of solenoid valve field.Chinese patent ZL87205710 discloses a kind of economize on electricity solenoid valve, and this solenoid valve adopts mechanical self-locking mechanism to come the folding condition of maintaining valve.Described self-locking mechanism comprises conduit and is plugged in the interior self-locking frame of conduit, is provided with a ring platform in the conduit, has the inclined-plane, location on the ring platform.Be provided with respect to the Huan Tai position on the self-locking frame and bump the pearl structure, bump the pearl structure and cooperate with location inclined-plane self-locking.Because this solenoid valve adopts and bumps pearl and locate mode that the inclined-plane cooperates and realize the folding self-locking of valve, after this solenoid valve uses a period of time, bump the phenomenon that the elasticity of the spring of pearl structure can occur reducing, this moment, the self-locking property of this solenoid valve will reduce, even the phenomenon of auto-lock function forfeiture can occur.
The model utility content
The purpose of this utility model provides a kind of self-locking electromagnetic valve, can occur along with the prolongation of service time descending in order to the auto-lock function that solves existing economize on electricity solenoid valve, or even the problem that completely loses of auto-lock function.
For achieving the above object, the utility model adopts following technological scheme: a kind of self-locking electromagnetic valve, comprise valve body and be arranged at valve body interior electromagnet and spool, be provided with axial self-locking mechanism between the iron core of described electromagnet and the spool, this axial self-locking mechanism comprises only revolves the connecting rod that is arranged in the valve body, one end and the iron core of connecting rod are connected, the other end is provided with a blind hole, be provided with ratchet mechanism in this blind hole, described ratchet mechanism comprises intermeshing ratchet and the bottom ratchet wheel gone up, described bottom ratchet wheel is connected mutually with connecting rod, press between the upper end of described upward ratchet and the bottom surface of blind hole and be provided with first Returnning spring, fixedlying connected with spool in the lower end, presses between described connecting rod and the valve body top to be provided with second Returnning spring.
Described electromagnet is provided with the apparent device in position, and this apparent device comprises apparent frizzen in position that is connected with the iron core of electromagnet and the photosensitive element that cooperates with the apparent frizzen triggering in position.
The seal face of described spool is provided with sealing gasket, and the face that described valve body seal face interior and spool is sealed and matched is provided with the sealing bulge loop.
Described valve body is made up of upper valve body that is fixed with one and following valve body, and sealing is fitted with fixed muffle in the described valve body down, and described connecting rod only revolves the sealing slip and is plugged in the fixed muffle.
Self-locking electromagnetic valve of the present utility model adopts the form of intermeshing ratchet to realize the self-locking of spool axial position, adopt the form of ratchet self-locking spring force decline can not occur and cause self-locking property to descend, or even auto-lock function situation about completely losing takes place, and effectively raises the performance and the working life of self-locking.Owing to adopted the self-locking structure of ratchet-type, then only need a pulse signal just can realize the transformation of this solenoid valve folding state, and do not need electromagnet is switched on for a long time, therefore compare saving power, also can not produce the problem of electromagnetic interference simultaneously.
As another improvement of the present utility model, this solenoid valve also has a display function, and the position display function is to realize by apparent frizzen in position and photosensitive element that mutual triggering cooperates.The iron core synchronization motion of apparent frizzen in position and electromagnet comes photosensitive element is triggered control.Just can know the residing folding condition of this solenoid valve very easily after having a display function.In addition, the seal face of spool is provided with a sealing gasket, and the position corresponding with sealing gasket is provided with the sealing bulge loop in the valve body, and sealing gasket is sealed and matched with the sealing bulge loop, has realized the soft seal of this solenoid valve, has improved sealing effect.
