Abstract
The utility model provides an electromagnetic control pressure self-adaption inlet and drainage valve and relates to the control technology of water inlet and drainage under different pressures. The electromagnetic control pressure self-adaption inlet and drainage valve comprises a water outlet (1), a rubber valve (2), a connecting rod (3), a water inlet (4), a rubber diaphragm plate (5), a piston (6), a piston valve body (7), a bulb pull rod (8), an electromagnetic valve housing (9), an elastic sleeve (10), an adjusting screw (11), a compression spring (12), an electromagnet (13), an electromagnetic iron core (14), a rubber seal ring (15) and a valve body (16). When the electromagnetic iron core (14) drives the piston (6) to move rightward and a valve base is opened, and the water inlet and drainage operations can be completed. When the valve base is closed under the elastic action of the compression spring (12) after power loss of the electromagnet (13), the operation for stopping the water inlet and drainage is achieved. The reliability of water inlet and drainage of the water valve under different pressures is improved and the electromagnetic control pressure self-adaption inlet and drainage valve has favorable pressure self-adaption capability for different water pressures.
Description
Technical field
The utility model relates to a kind of water-inflow and drain valve device, particularly a kind of pressure adaptive formula water-inflow and drain valve device of Electromagnetic Control.
Background technique
Washing machine need to adopt inlet valve to control water inlet, Chinese patent notification number CN201661752U, the day for announcing is on December 01st, 2010, name is called and in " without pressure electromagnetic valve ", discloses a kind of travel(l)ing rest that is to be set with on diaphragm, iron core underpart is stretched in travel(l)ing rest and is positioned at the center hole top on travel(l)ing rest, in the groove on travel(l)ing rest top, be provided with the device of the jump ring that travel(l)ing rest is flexibly connected with iron core lower end recess, its deficiency is that the hydraulic pressure of water inlet system is had to requirement, this device is only applicable to the situation that hydraulic pressure is lower, once hydraulic pressure raises, this device is difficult to reach the requirement that guarantees Open valve.Up to the present, on market, there is not yet the pressure adaptive formula water-inflow and drain valve of Electromagnetic Control.
Summary of the invention
The purpose of this utility model is to overcome the existing deficiency of entering draining control valve, provide a kind of simple in structure, can be under various hydraulic pressure the feeding/discharging device of stable water supply, improve the reliability into draining.
The pressure adaptive formula water-inflow and drain valve of Electromagnetic Control of the present utility model is comprised of water outlet (1), rubber valve (2), connecting rod (3), water intake (4), rubber diaphragm (5), piston (6), piston valve body (7), ball-head tension rod (8), solenoid valve casing (9), spring housing (10), adjustment screw (11), holddown spring (12), electromagnet (13), electromagnetic core (14), rubber seal (15), valve body (16) etc.
The equal diameters of described rubber valve (2) and piston (6), under solenoid valve power failure state, when current enter body cavity from water intake (4), barrier effect due to rubber diaphragm (5), current can only rest on this cavity, now no matter pressure is to be greatly little to the water in this cavity, because the equal diameters of rubber valve (2) and piston (6), acting on rubber valve (2) equates with the amount of force on piston (6), opposite direction, so water outlet (1) can not be opened voluntarily by hydraulic pressure; Under solenoid valve obtains electricity condition, under electromagnetic force, electromagnet (13) attracts electromagnetic core (14) to move to right, and drive piston (6) to move to right by ball-head tension rod (8), open rubber valve (2), equally due to the equal diameters of rubber valve (2) with piston (6), acting on rubber valve (2) equates with the amount of force on piston (6), opposite direction, now only need less electromagnetic force just can open rubber valve (2), complete into water effect, because electromagnetic force and the hydraulic pressure size of needs are irrelevant, so this water inlet valve system can be realized hydraulic pressure self adaption; When solenoid valve is again after dead electricity, under holddown spring (12) elastic force effect, electromagnetic core (14) moves to left, and promotes ball-head tension rod (8), piston (6), rubber valve (2) and moves to left, and closes into water path.
Compared with prior art, the beneficial effects of the utility model are: (1) is simple in structure, are easy to manufacture; (2) be adapted to different hydraulic pressure, particularly the in the situation that of water pressure fluctuations, realize self adaption water inlet; (3) adopt lamina membranacea and seal ring double protection mechanism, the electric leakage of avoiding solenoid valve water inlet to cause, had both guaranteed the normal use of equipment, can prevent again the generation of electric shock accidents.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
In Fig. 1, under solenoid valve power failure state, when current enter body cavity from water intake (4), barrier effect due to rubber diaphragm (5), current can only rest on this cavity, now no matter pressure is to be greatly little to the water in this cavity, because the equal diameters of rubber valve (2) and piston (6), acting on rubber valve (2) equates with the amount of force on piston (6), opposite direction, thus water outlet (1) can not be opened voluntarily by hydraulic pressure, now, under the effect of holddown spring (12), water outlet is in the state of closing.
In Fig. 2, under solenoid valve obtains electricity condition, under electromagnetic force, electromagnet (13) moves to right after attracting electromagnetic core (14) and overcoming holddown spring (12) elastic force, and drive piston (6) to move to right by ball-head tension rod (8), open rubber valve (2), equally due to the equal diameters of rubber valve (2) with piston (6), acting on rubber valve (2) equates with the amount of force on piston (6), opposite direction, now only need less electromagnetic force just can open rubber valve (2), complete into water effect, because electromagnetic force and the hydraulic pressure size of needs are irrelevant, therefore this water inlet valve system can be realized hydraulic pressure self adaption, when solenoid valve is again after dead electricity, under holddown spring (12) elastic force effect, electromagnetic core (14) moves to left, and promotes ball-head tension rod (8), piston (6), rubber valve (2) and moves to left, and closes into water path.
