Abstract
The utility model relates to a magnetic-keeping electromagnetic valve which comprises a valve body. The valve body is internally provided with a valve chamber, an air inlet passage and an air outlet passage, wherein the air inlet passage and the air outlet passage are communicated with the valve chamber respectively. The valve chamber is internally provided with a coil and a valve core. The air inlet of the air outlet passage is fixedly provided with a sealing seat in a sealing manner, and the sealing seat is internally provided with an air hole that is communicated with the air outlet passage. The end surface of the sealing seat, close to the valve core, is provided with a ring-shaped protrusion that is coaxially arranged with the air hole; the valve core and the ring-shaped protrusion are matched with each other when in opening and closing; the middle part of the coil is fixedly provided with a permanent magnet; one side of the permanent magnet, close to the valve core, is provided with a magnetic-conductive cushion block; a spring is press-mounted between the magnetic-conductive cushion block and the valve core; and a valve core motion clearance is arranged between the magnetic-conductive cushion block and the valve core. The electromagnetic valve adopts realizes the opening and closing of the valve by mutually fitting of the valve core and the ring-shaped protrusion; as the contacting area of the valve core and the ring-shaped protrusion is smaller, the effective action area of the air pressure is reduced, the opening force of the valve is reduced, therefore, the electromagnetic valve can be applied to the environment of high atmospheric pressure.
Description
Technical field
The utility model relates to a kind of magnetic holding solenoid valve, belongs to the air-operated solenoid valve technical field.
Background technique
Chinese patent ZL99231950.1 discloses a kind of magnetic holding solenoid valve, and this magnetic holding solenoid valve comprises coil, permanent magnet, dry reed-pipe, spring, packing ring and housing.Housing top is provided with seat board, seat board is provided with the iron yoke, be in series or in parallel with coil between seat board and the iron yoke, be provided with the permanent magnet of annular and the support block of annular between the coil, slidable fit has an iron core in the center hole of coil, iron core is corresponding with the position of permanent magnet, and the lower end of this iron core is connected with a spool by core bar.Though this magnetic holding solenoid valve has been realized the mode of employing permanent magnet and has been kept the opening state of valve, has realized purpose of energy saving, because the restriction of its structure, this magnetic holding solenoid valve can not be used for the highpressure field.
The model utility content
The purpose of this utility model provides a kind of magnetic holding solenoid valve, can not be applied in problem in the highpressure field in order to solve existing magnetic holding solenoid valve.
For achieving the above object, the utility model adopts following technological scheme: a kind of magnetic holding solenoid valve, comprise valve body, be provided with valve pocket and gas-entered passageway that is communicated with valve pocket respectively and outlet passageway in the valve body, be provided with coil and spool in the described valve pocket, the suction port place sealing of described outlet passageway is installed with sealing seat, be provided with the pore that is communicated with outlet passageway in the sealing seat, sealing seat is provided with annular protrusion near the end face of spool end, this annular protrusion and the coaxial setting of described pore, described spool open and close with annular protrusion and cooperate; The middle part of described coil is installed with permanent magnet, and this permanent magnet is provided with magnetic cushion block near a side of spool, presses between described magnetic cushion block and the spool to be provided with spring, and is provided with the valve core movement gap between magnetic cushion block and the spool.
The outside of described coil is set with first sleeve that is sealed and matched with valve pocket, and the outside of described spool is set with second sleeve, and first sleeve and the second sleeve opposite end have clamped the adjustment pad.
Described cushion block is set with magnetism resistent ring near the spool end.
Magnetic holding solenoid valve of the present utility model, the suction port place sealing of its outlet passageway is installed with sealing seat, is provided with the pore that is communicated with outlet passageway in the sealing seat, and sealing seat is provided with annular protrusion near the end face of spool end, and annular protrusion opens and closes with spool and cooperates.Because it is smaller that annular protrusion can be done, so just reduced the effective active area of air pressure, and then the opening force can reduce under the uniform pressure condition this solenoid valve and open the time, same working as adopts identical opening force to be, pressure in the loop that this valve can be controlled also can be higher, so this magnetic holding solenoid valve can be applied in the highpressure loop.
Another improvement of the present utility model is, clamped the adjustment pad at first sleeve and the second sleeve opposite end, can change the number of adjusting pad according to actual conditions like this and change and be provided with the valve core movement gap between magnetic cushion block and the spool, and then the stroke of adjusting spool is realized accurate quick control.
Improvement more of the present utility model is, is set with a magnetism resistent ring in the outside of cushion block, magnetism resistent ring was set after electromagnet when energising, can form a closed magnetic circuit through first sleeve, spool, magnetic cushion block and permanent magnet.The polarity of the power supply by changing electromagnet realizes the keying control of valve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, magnetic holding solenoid valve of the present utility model comprises a valve body 4, is provided with a valve pocket that is ladder-type in the valve body 4, also is provided with the gas-entered passageway 8 and the outlet passageway 9 that are connected with valve pocket respectively on the valve body.Be provided with outer coil 1 and inner spool 5 in the valve pocket.The suction port place sealing of outlet passageway 9 is installed with sealing seat 10, be pressed with sealing gasket between the front end of sealing seat 10 and the valve pocket, be provided with the pore that is communicated with outlet passageway 9 in the sealing seat 10, sealing seat 10 is provided with annular protrusion near the end face of spool 5 ends, this annular protrusion and the coaxial setting of described pore, described spool 5 open and close with annular protrusion and cooperate.The middle part of coil 1 is equipped with a permanent magnet 2, the front end of this permanent magnet 2 is provided with one first magnetic cushion block 12, the front side of first magnetic cushion block 12 is set with a magnetism resistent ring 7, the rear end of this permanent magnet 2 is provided with one second magnetic cushion block 14, press between described first magnetic cushion block 12 and the spool 5 and be provided with spring 11, and be provided with the valve core movement gap between first magnetic cushion block 12 and the spool 5.The outside of coil 1 is set with first sleeve 13 that is sealed and matched by seal ring with valve pocket, and the outside of spool 5 is set with second sleeve, 6, the first sleeves 13 and second sleeve, 6 opposite ends have clamped one group of adjustment pad 3.The rear side of first sleeve 13 is provided with a cushion block, and the rear side of cushion block is provided with a gland nut that is spirally connected with valve body.
This magnetic holding solenoid valve feeds one when need be with opening of valves and makes coil produce a pulse signal that magnetic field of permanent magnet is strengthened in use, at the effect lower valve core in magnetic field to permanent magnet one lateral movement, and finally by the opening state of permanent magnet sticking maintaining valve.When the needs cut-off valve, feed a reverse pulse signal, this moment, the magnetic field of permanent magnet was weakened, and under the effect of spring, spool is to away from permanent magnet one lateral movement, and final and annular protrusion is sealed and matched.
