Abstract

The utility model discloses an energy-saving soundless ac or dc electromagnetic liquid (gas) discharging valve, particularly a drainage valve for a washing machine, mainly comprising a valve body (2) with a water inlet (8) and a water outlet (3) whose position is below than the position of the water inlet (8), wherein, the valve body (2) is provided with a curved water-stopping opening (10), a stopper, and a DC solenoid electromagnet (1), the movable iron core (6) of the valve body (2) is connected with the stopper through a connecting rod (7), and the bottom of the valve body (2) is provided with a hand water-discharging button (4). The device has the advantages of simple structure, little noise, energy saving, electricity saving, and low cost.

Description

Energy-saving soundless ac or dc electromagnetic discharging valve

The utility model relates to solenoid valve, further is meant electromagnetism discharge opeing (gas) valve.

There is the big or defect of high cost of noise in existing discharge opeing (gas) valve.For example the drain valve of domestic washing machine adopts alterating and direct current magnet tractive to open the valve of being pushed down by spring and realize draining more, and its noise is big, and the cover electronic circuit output DC that also needs that has is given DC electromagnet, and power consumption is more than 20 watts.In order to overcome this people's of bothering noise, the washing machine that has adopts goes up drainage pattern, promptly with the driven by motor water pump water is discharged, and pump power is about about 90 watts, and power consumption is big, the installation cost height.

The purpose of this utility model is, designs a kind of energy-saving, noiseless alterating and direct current magnetic discharging (gas) valve, have energy-conservation, noiseless, cost is low and the characteristics of reliable performance and AC/DC universal.

Technical solution of the present utility model is, valve body has water intake and is lower than the drain opening of water intake, it is the sealing mouth of curved surface and the plug that corresponding surface is arranged and be mated that sidewall is arranged in the valve body, valve body top is connected to tube core, in this tube core iron core is arranged, there is electromagnetic coil its outside, constitutes solenoid electromagnet thus, described iron core is connected with plug through connecting rod, rectifying device with the commercial power rectification after (or connecing direct current) power to electromagnet.Also can the button that manually discharges water be installed in the valve body bottom.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings: Fig. 1 is a practical structures;

Fig. 2 is a kind of practical structures of rectifier;

Fig. 3 is an another kind of structure of the present utility model.In the drawings:

1-electromagnet 7-connecting rod

2-valve body 8-water intake

3-drain opening 9-plug

The 4-button 10-sealing mouth that manually discharges water

5-tube core 11,12-power output end

6-moves iron core

By accompanying drawing as can be known, the utility model comprises valve body (2), this valve body (2) has water inlet (8) and is lower than the discharge outlet (3) of water inlet (8), it is the waterstop port (10) of curved surface and the plug (9) that corresponding surface arranged and cooperate with it that sidewall is arranged in the valve body (2), valve body (2) top is connected to tube core (5), and iron core (6) is arranged in this tube core (5). Should can make of metal or nonmetal soft magnetic materials by moving iron core (6), its cross sectional shape is done rectangularity, circle or ellipse garden shape and all can. Described tube core (5) is as coil rack, and there is solenoid its outside, consists of thus solenoid electromagnet (1). Moving iron core (6) is connected with plug (9) through connecting rod (7), and fairing provides direct current with the backward electromagnet in commercial power rectification, also accessible direct current. In order can a manual drainage button to be installed in valve body (2) bottom having a power failure or draining during maintenance, it comprises push rod, back-moving spring and bayonet lock (ring), and its push rod can be with plug (9) jack-up in the valve body (2). Described fairing can adopt structure shown in Figure 2, be that the negative pole of diode D1 joins with an end of solenoid and it just very connects a power input (11) of civil power, be attempted by two exits of solenoid behind diode D2 and resistor (R) series winding and the negative pole of D2 links to each other with the negative pole of D1, the other end of solenoid is power input (12) again. The curved surface of the waterstop port (10) in the described valve body (2) and the corresponding surface of plug (9) are billiard table, spherical crown shape, can also be cone (platform) bodies; They can be manufactured with flexible materials such as rubber, also can manufacture with rigid materials such as duroplasts materials.

Principle and the process of this device work is (referring to accompanying drawing), and electromagnet is connected civil power, just partly During week, D1 conducting in the rectifier, D2 cut-off, negative half, D1 cut-off, D2 conducting afterflow (R is current-limiting resistance) during rectifier, coil passes through direct current all the time; Valve open, realization draining are upwards mentioned plug (9) in the adhesive that make progress of moving iron core (6) by connecting rod (7). After the electromagnet dead electricity, iron core (6) and plug (9) are because of the gravity valve-off that falls voluntarily.

From the above, collisionless during owing to moving iron core (6) action can not produce any noise, thereby overcome the big major defect of prior art noise. This valve is because of its structural principle, and power consumption is below 10 watts, and economize on electricity significantly. By accompanying drawing as can be known, it also has simple in structure, and cost hangs down the characteristics with dependable performance. Be suitable for use as various liquid and gas bleed valve, be particularly suited for existing For Drain Valve of Washing Machine and do not need washing machine is done any change.

Embodiment 1: this valve by structure illustrated in figures 1 and 2, be designed to white clouds board washing machine drainage valve, and electromagnet and valve body are one, the water-in and water-out bore of valve is 3cm, adopts engineering plastics to make.Press height of water level 80cm design, electromagnet is during for 250 volts of Ac, 9 watts of power consumptions, and during 180 volts of supply voltages, about 6 watts of power consumption.Moving iron core adopts the metal soft magnetic material ordinary low-carbon steel to make.When height of water level was lower than 80cm, power consumption also can further reduce.

Embodiment 2: press this device of Fig. 3 and structure shown in Figure 2, the length of corresponding on demand lengthening tube core (5), and the corresponding long connecting rod (7) that adds make electromagnet be installed in washing machine top, and all the other parameters are with embodiment 1.
