Description

A kind of automatic water-supply control valve

The utility model belongs to a kind of water supply control valve door of tap water, particularly a kind ofly is suitable for electronically controlled automatic water-supply valve.

Present existing approaching automatic control water supply valve, No. 892142324 patents that the applicant is arranged, structural feature is that the valve back side has a negative cavity, water inlet and spilled water hole are arranged on the valve, rise by coil electromagnetism power and the lifting element that depends on spring force to descend comes the switch spilled water hole with one, disappear and open or negative pressure forms and closes in negative pressure with control valve.Owing to lifting element is to rise and keep it to rise attitude by coil electromagnetism power, so the valve opening process needs energising always, this not only the electricity consumption time long but also power consumption is many, so need external public power, the sense of insecurity that this increases the user also is an impediment to refined.

The purpose of this utility model provides a kind of improved automatic water-supply control valve, and short and little power consumption of its electricity consumption time can use self-contained battery as power supply, can increase user's the sense of security, and is also more refined.

The utility model is achieved in that a kind of automatic water-supply control valve, comprise valve body, valve, lifting element, spring, coil block, wherein valve has water inlet and water hole, pond, the water inlet leads to negative cavity by the valve inleting water mouth, spilled water hole leads to the valve body water outlet by negative cavity, lifting element is positioned at the spilled water hole top, it is characterized in that control valve also includes permanent-magnet component, permanent-magnet component comprises permanent magnet, magnet case, last magnetic absorbing mass, following magnetic absorbing mass, on, following magnetic absorbing mass be each positioned at lifting element on, the below, magnet case connects and places permanent magnet and last, between the following magnetic absorbing mass, described coil block comprises the suction coil, coil falls in suction, coil carrier and the coil power line that connects power control circuit.

The improvement main points of such scheme are after lifting element is subjected to coil to attract rising or decline, by last, following magnetic absorbing mass keeps its liter to its attraction, state falls, because it is last, the magnetic attraction of following magnetic absorbing mass is to pass to it by permanent magnet by magnet case, so lifting element keeps its liter, the state of falling is by permanent-magnet attractive power rather than electromagnetic attraction, needing electricity consumption only is that coil attracts its liter, the moment of falling, so the electricity consumption time is short and power consumption is few, can solve electrical problem and needn't take civilian public power with the dryelement cell that is loaded in the valve, this can increase user's the sense of security, owing to removed the outer power line that draws, the outside is also more refined simultaneously.The spring of such scheme is to close the reliability of spilled water hole and establish in order further to strengthen lifting element.

Below in conjunction with accompanying drawing the utility model is done to describe more specifically.

Fig. 1 is the cross-sectional schematic of a kind of scheme of the utility model.

With reference to Fig. 1, this automatic water-supply control valve, comprise by the fastening valve body that constitutes 1 of polylith, valve 2, lifting element 3, spring 4, coil block 5, wherein valve 2 has water inlet 6 and spilled water hole 7, water inlet 6 leads to negative cavity 9 by valve body 1 water intake 8, spilled water hole 7 leads to valve body 1 water outlet 10 by negative cavity 9, lifting element 3 is positioned at spilled water hole 7 tops, spring 4 is positioned at above the lifting element 3, feature is that control valve also comprises permanent-magnet component, this permanent-magnet component bag is according to permanent magnet 11 and 12, magnet case 13 and 14, last magnetic absorbing mass 15, following magnetic absorbing mass 16, on, following magnetic absorbing mass 15,16 be each positioned at lifting element 3 on, the below, magnet case 13 (14) connects and places permanent magnet 11 (12) and magnetic absorbing mass 15 up and down, between 16, described coil block 5 comprises suction coil 17, coil 18 falls in suction, coil carrier 19 and 20, be access to the coil power line 21 and 22 of power control circuit.In addition, valve 2 is made of the valve body 23 of hard and soft rubber parts 24; On the upper and lower magnetic absorbing mass 15,16 Sealing 25,26 is housed also; There is a set screw 27 last magnetic absorbing mass 15 tops; Lifting element 3 heads also have rubber parts 28.

During use, this automatic water-supply valve is loaded on installs in the valve casing 29, coil power line 21 and 22 is connected to the power control circuit 30 in the valve casing 29, and dryelement cell 31 provides power supply by circuit 30 to control valve.When lifting element 3 is in decline state as Fig. 1, lifting element 3 is attracted by magnetic absorbing mass 16 and keeps the decline state and close spilled water hole 7, spring 4 can further be strengthened it and close reliability, at this moment tap water enters negative cavity 9 through water intake 8, water inlet 6, valve 2 is exerted pressure and is reached close water outlet 10; When needs supply water, control circuit 30 is transported to suction coil 17 to the power supply of dryelement cell 31, lifting element 3 is sucted liter, magnetic absorbing mass 15 in the contact and keep rising attitude, and at this moment control circuit 30 is supply disconnecton, because spilled water hole 7 is opened, water in the negative cavity 9 releases from spilled water hole 7, and releases the enter flow of flow greater than water inlet 6, so the pressure of 9 pairs of valves 2 of negative cavity discharges, the tap water of water intake 8 struts valve 2 and enters water outlet 10 from the below, realize supplying water.As needs Guan Shuishi, control circuit 30 transfers to power supply to inhale and falls coil 18, and lifting element 3 declines contact with following magnetic absorbing mass 16 and keep falling attitude, and at this moment control circuit 30 is supply disconnecton, and lifting element 3 is closed spilled water hole 7 again, and negative pressure is closed valve 2 again.Permanent magnet the 11, the 12nd passes to upper and lower magnetic absorbing mass 15,16 to permanent magnetism suction by magnet case 13,14.
