Abstract
Disclosed is a miniature ball-core solenoid valve which comprises an excitation coil and a valve body. The valve is characterized in that a water inlet is arranged at one side of the valve body, the middle of the valve body having a cavity with a fountain mouth, a steel ball placing below the water inlet of the fountain mouth. A base is installed over the valve body, the water outlet of the fountain mouth passes through the base, seal rings are arranged at the joints of the fountain mouth, the valve body and the base, the excitation coil with the steel core is installed on the lower end of the valve body. The miniature ball-core solenoid valve is simple in structure, cheap in price and high in sensitivity and is initiate for the current market, and can be widely used in water dance fountain control for arts and crafts.
Description
Technical field
The utility model relates to solenoid valve, particularly a kind ofly makees the micro-ball core solenoid valve that spool is controlled the water route break-make with steel ball.
Background technique
At present, the most complex structure of the solenoid valve on the market, volume is bigger, the price height.Some low-cost solenoid valve, especially miniature electromagnetic valves but exist sensitivity low, problems such as action instability.
Summary of the invention
In view of the above-mentioned defective of prior art, the utility model proposes a kind of simple in structure, low price and highly sensitive micro-ball core solenoid valve.
The utility model micro-ball core solenoid valve comprises field coil 7 and valve body 4, one side of described valve body 4 is provided with water intake, there is inner chamber at valve body 4 middle parts, water spout 1 is installed in the inner chamber of valve body 4, a steel ball 6 is placed in the below of water spout 1 water intake, the top mounting base 3 of valve body 4, and the water outlet of water spout 1 passes pedestal 3, seal ring 2 is installed in the connecting part of water spout 1, valve body 4 and pedestal 3, and the field coil 7 of ribbon core 8 is installed in the lower end of valve body 4.
This micro-ball core electromagnetic valve structure is simple, and is cheap, highly sensitive, is the existing market initiative, can be widely used in the control of artwork water dance fountain.
Description of drawings
Fig. 1 is the structural drawing of this micro-ball core solenoid valve;
Fig. 2 is its side view;
Fig. 3 is its plan view;
Fig. 4 is its worm's eye view.
Exemplary embodiments
Further specify below in conjunction with accompanying drawing.
With reference to Fig. 1-4, this micro-ball core solenoid valve comprises field coil 7 and valve body 4, one side of described valve body 4 is provided with water intake, there is cylindrical cavity at valve body 4 middle parts, and water spout 1 is installed in the inner chamber of valve body 4, and a steel ball 6 is placed in the below of water spout 1 water intake, the top mounting base 3 of valve body 4, the water outlet of water spout 1 passes pedestal 3, and seal ring 2 is installed in the connecting part of water spout 1, valve body 4 and pedestal 3, and the field coil 7 of ribbon core 8 is installed in the lower end of valve body 4.
Field coil 7 among the embodiment comprises skeleton 9, is installed in the cylinder-shaped iron core 8 in the skeleton 9, and is wrapped in the line bag on the skeleton 9.
The iron core 8 of field coil 7 and water spout 1 are on the same center line, and like this, the line of field coil 7 is surrounded by electric current when flowing through, and will produce the strongest attraction force to the steel ball under the water spout 1, thereby have guaranteed the sensitivity of solenoid valve.
The water intake of water spout 1 is a funnel shape, like this, when having water to flow into the inner chamber of valve body 4, the pressure of water floats steel ball 6, the steel ball 6 that floats just in time embeds the bottom of funnel, the water intake of water spout 1 is blocked, and this special shape makes steel ball not swing to the next door, has guaranteed the stability of solenoid valve action.In the enforcement, also can adopt inner ball surface shape or other shape.
With reference to Fig. 1,4, the skeleton 9 of valve body 4 wherein, pedestal 3 and field coil 7 is fastening by screw.In the enforcement, also can adopt fastening or other fastening means of rivet.
The internal diameter of water spout 1 water outlet of miniature electromagnetic valve is ￠ 0.5-1.2mm, can be widely used in the control of artwork water dance fountain.
The working principle of this miniature electromagnetic valve is as follows:
Behind the water intake inflow inner chamber of water by valve body 4, the pressure of water makes on the steel ball 6 in the inner chamber and moves, finally blocked the water intake of water spout 1, when having electric current to flow through in the line bag of field coil 7, the end of its iron core 8 generates an electromagnetic field, when this electromagnetic field to the attraction force of steel ball 6 greater than water during to the pressure of steel ball, steel ball 6 will be adsorbed on the surface of internal cavity with the valve body 4 of iron core 8 tight cards, so the water intake of water spout 1 is opened, water is from water spout 1 ejection; When the electric current that flows through field coil 7 is reduced to enough little or disappeared, also will weaken or disappear in the magnetic field of iron core 8 ends, and under the effect of hydraulic pressure, steel ball 6 moves on again, and the water intake of water spout 1 is blocked, and reaches the effect of water shutoff.
