Abstract
The utility model discloses a manual control device on a solenoid valve. The manual control device comprises a guide sleeve, a rotating trough, a pull rod and a top cap. An installation hole is formed in the side wall of the guide sleeve. A hinge pin is inserted into the installation hole. A groove used for accommodating the hinge pin is formed in the rotating trough. A notch is formed in the side, opposite to the groove, of the rotating trough. One side wall of the groove is lower than the other side wall of the groove. The rotating trough is arranged in a cavity in one end of a fixed magnet in a sleeved mode. The guide sleeve is arranged inside the rotating trough in a sliding mode. The pull rod penetrates through the guide sleeve, and one end of the pull rod is directly or indirectly connected with a valve element of the solenoid valve. The top cap is fixed to one side of the guide sleeve. When the solenoid valve is powered off, it takes little effort to open or close the solenoid valve manually; only a pressing cap needs to be rotated to make the hinge pin enter the notch, the top cap is pulled upwards at this time, the top cap drives the pull rod, the pull rod drives the valve element, and therefore the solenoid valve can be opened or closed.
Description
Technical field
The utility model relates to the manual overvide on a kind of solenoid valve, belongs to hydrovalve technical field.
Background technique
Manual overvide generally on solenoid valve, is all equipped with, for realizing the manually opened of solenoid valve closed when the solenoid valve power-off.Traditional manual overvide mainly comprises connecting rod and nut, and one end of connecting rod is connected with moving iron, and moving iron is fixedly connected with spool, by turning nut, nut band movable valve plug is moved horizontally in valve pocket, thereby realizes the manually opened of valve and close.The operation of the manually opened or throttle down of this structure is relatively wasted time and energy.Therefore be necessary to make improvements.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the manual overvide on a kind of solenoid valve.
The utility model is achieved by the following technical solution: the manual overvide on a kind of solenoid valve, comprise guide sleeve, swivelling chute, pull bar and top cap, sidewall at described guide sleeve is offered mounting hole, in described mounting hole, plug a bearing pin, on described swivelling chute, be provided for holding the groove of described bearing pin, the side that swivelling chute is relative with described groove arranges breach, and the sidewall of groove one side is lower than the sidewall of opposite side; Described swivelling chute is sheathed in the described cavity of determining iron one end, described guide sleeve slides and is arranged in described swivelling chute, also comprise a pull bar, described pull bar passes through described guide sleeve and one end of pull bar and the spool of solenoid valve and directly or is indirectly connected, and described top cap is fixed on a side of described guide sleeve.
The utlity model has following beneficial effect: when solenoid valve power-off, manually opened or throttle down is more laborsaving, only need to rotate pressure cap, make bearing pin enter breach, now can by draw top cap, top hatband moves pull bar, pull bar band movable valve plug, thus realize the unlatching of valve or close object.

Embodiment
Below the utility model is described in further detail, referring to Fig. 3 to Fig. 5, shown in Fig. 3 to Fig. 5 is a kind of solenoid valve with the utility model manual overvide, comprises guide pin bushing 1, in one end of described guide pin bushing 1, be fixedly installed and determine iron 2, in the cavity of guide pin bushing 1, slide moving iron 3 is set; Coil, described coil is coated on guide pin bushing 1 outside, provides and make described moving iron 3 determine to described the magnetic field that iron 2 moves under coil "on" position; Valve pocket 4, described valve pocket 4 is fixedly installed on one end of described guide pin bushing 1, and described valve pocket 4 has the cavity being communicated with described guide pin bushing 1 cavity, at end and the sidewall of described valve pocket 4, offers respectively the first hydraulic fluid port 40 and the second hydraulic fluid port 41 being communicated with valve pocket cavity; Main valve plug 5, described main valve plug 5 slides and is arranged at the inner chamber of described valve pocket 4, and has hollow cavity, in described main valve plug 5 ends, offers the oil inlet hole 50 being communicated with its inner chamber, and described main valve plug sidewall offers the oil outlet 51 being communicated with its inner chamber; Poppet valve core 6, described moving iron 3 is fixed in one end of described poppet valve core 6, and described poppet valve core 6 stretches into described main valve plug 5 and the other end of described poppet valve core 6 and the oil inlet hole of described main valve plug 5 coordinated realize unidirectional oil-feed; One end of described poppet valve core 6 is provided with fixture block 60, and one end that described moving iron 3 coordinates with described poppet valve core 6 has the draw-in groove 30 coordinating with described fixture block 60.
Referring to Fig. 1 to Fig. 2, manual overvide on the utility model solenoid valve, be arranged in above-mentioned solenoid valve, comprise guide sleeve 7, swivelling chute 8, pull bar 9 and top cap 10, at the sidewall of described guide sleeve 7, offer mounting hole 70, in described mounting hole 70, plug a bearing pin 71, on described swivelling chute 8, be provided for holding the groove 80 of described bearing pin 71, the side that swivelling chute 8 is relative with described groove 80 arranges breach 81, and the sidewall of groove 80 1 sides is lower than the sidewall of opposite side; Described swivelling chute 8 is sheathed in the described cavity of determining iron 2 one end, described guide sleeve 7 slides and is arranged in described swivelling chute 8, described pull bar 9 one end have the head 90 expanding, the head that described pull bar 9 expands by described guide sleeve 7 and pull bar leans the step surface of described moving iron 3 inner chamber body, and described top cap 10 is fixed on a side of described guide sleeve 7.
When the electromagnet no electric circuit of solenoid valve, the first hydraulic fluid port is equivalent to one-way valve to the second hydraulic fluid port, the first hydraulic fluid port pressure raises while surpassing the cracking pressure of one-way valve, main valve plug is opened fluid and is flowed from the first hydraulic fluid port to the second hydraulic fluid port, when coil electricity, the second hydraulic fluid port is opened to the first hydraulic fluid port, and the first hydraulic fluid port only has a small amount of fluid to flow out by filler opening to the second hydraulic fluid port.While requiring the second hydraulic fluid port to open to the first hydraulic fluid port when the coil no electric circuit of solenoid valve, can by under the cap 10 that bears down on one, make bearing pin 71 depart from described groove 80, then rotate described pressure cap 10, make bearing pin 71 enter described breach 81, now can by draw top cap 10, top cap 10 drives pull bar 9, pull bar 9 drives described moving iron 3 and poppet valve cores 6, thereby one end that the oil inlet hole 50 of poppet valve core 6 one end and described main valve plug 5 is coordinated is separated, and now fluid can enter the first hydraulic fluid port by the second hydraulic fluid port.
In the present embodiment, the structure of solenoid valve only, for for the principle of the utility model manual overvide is described, is not interpreted as because working as the protection domain that limits the application of the utility model manual overvide.
