Abstract
The utility model relates to an antishock slow-opening electromagnetic valve which comprises a valve body, a valve cover, a valve plate, a movable iron core, a coil case, a coil, a fixed iron core and a rectifying device, wherein, the movable iron core is connected with the valve plate; a reset spring is arranged on the valve core; a through hole is arranged on the fixed iron core; the movable iron core can slide up and down in the through hole of the fixed iron core; the top end of the fixed iron core is provided with a hydraulic regulator; and the hydraulic regulator comprises an oil cylinder body, a piston, a throttle regulator, a stroke regulator and a reset mechanism. The goals of slow opening, fast closing and adjustable flow rate are achieved, and the sectional control modes of fast opening at a small flow rate and slow opening at a large flow rate are realized.
Description
Technical field
The utility model relates to solenoid valve, specifically be a kind of can be when solenoid valve be opened, the ascending slow open electromagnetic valve of peaked protecting against shock that slowly reaches of flow.
Background technique
Rock gas uses solenoid valve to control the conveying of rock gas when line transportation, and the opening and closing of general solenoid valve all are to open fast and quick closedown, many times requires slowly ascending of solenoid valve energy control flow rate, satisfies the requirement of slow opening fast shutting.
The model utility content
The purpose of this utility model is at the problems referred to above, proposes a kind of slow unlatching, quick closedown, flow is adjustable the slow open electromagnetic valve of protecting against shock.
The purpose of this utility model is achieved in that the slow open electromagnetic valve of protecting against shock of the present utility model, it comprises valve body, valve gap, valve block, moving iron core, coil case, coil, fixed core, rectifying device, above-mentioned moving iron core is connected with valve block, Returnning spring is arranged on the valve block, through hole is arranged on the fixed core, moving iron core can slide up and down in the through hole of fixed core, there is a hydraulic regulating device on the top that it is characterized in that fixed core, above-mentioned hydraulic regulating device comprises outer cover, cylinder body, piston, there is adpting flange the lower end of cylinder body, the center thimble is arranged in the middle of the adpting flange, the center thimble touches mutually with piston, and orifice sleeve and throttling pin are arranged on the cylinder body, and there is nut the upper end of cylinder body, the stroke adjustment cover, stroke regulating lever and saturating lid, nut and cylinder body are slidingly matched, the stroke adjustment cover cooperates with nut thread, and stage clip and Non-return ring are arranged on the stroke regulating lever, pod apertures is arranged and the runner that resets on the piston, resetting has check valve sheet and stage clip on the runner, and Returnning spring is arranged on the piston.
The slow open electromagnetic valve of protecting against shock of the present utility model, under the situation of energising, inhale on the moving iron core, drive valve block and open solenoid valve, the upper end of moving iron core promotes the center thimble of hydraulic regulating device, the center thimble promotes piston stroking upward, by hydraulic way controlled motion speed, cylinder body epicoele hydraulic oil enters the cross through hole of orifice sleeve by cavity top side opening, regulates the throttling pin and can regulate flow, reach the control piston speed uplink, thus change piston in effective travel on line time; The effective travel of piston is by nut control, and the rotational travel adjustment sleeve can be adjusted nut and move up and down, and piston stroking upward is the piston stroke stop to the bottom surface of nut; Adjust stroke regulating lever downwards, stage clip on the stroke regulating lever is fitted Non-return ring and piston, speed uplink adjusts upward stroke regulating lever by the control of throttling pin, and Non-return ring separates with piston, hydraulic oil oil guiding hole in the middle of piston freely passes through, can make piston stroking upward obtain one section free travel, the realization solenoid valve was opened fast in the small flow stage, and hydraulic oil is cut off after Non-return ring and piston applying, piston stroking upward is slowly opened solenoid valve by the control of throttling pin.Behind the solenoid valve shuts power supply, moving iron core is resetted by Returnning spring and closes solenoid valve, and the center thimble of hydraulic regulating device is also resetted by Returnning spring, and the check valve sheet on the runner that resets on the piston is by the jack-up that makes progress, and hydraulic oil is bottom-up to be passed through, and makes piston reset.Therefore, the slow open electromagnetic valve of protecting against shock of the present utility model can reach slow unlatching, quick closedown, purpose that flow is adjustable, can also realize the segmentation control mode that small flow is opened fast and big flow is opened slowly.
