Abstract

The utility model relates to an energy-saving electromagnetic valve with low consumption and low voltage, composed of a valve cover (11) and a valve body (8). The valve cap (11) is provided with an exciting coil (5), a fixed iron core (10), a movable iron core (9), and a magnetic steel (3). When using, positive and reversal instantaneous micro current is conducted and then the functions of opening and closing the valve can be realized. The energizing time is short and the operating voltage is low, which lowers the energy consumption, achieves the design requirements of low power consumption and low voltage. The utility model is used by matching with magnetic card or intelligent type gas meters and water meters.

Description

Low power consumption low voltage energy-saving electromagnetic valve

The utility model relates to structural design a kind of and gas meter and the matching used special electromagnetic valve of water meter.

Solenoid valve is widely used as the final controlling element of control automatically, existing solenoid valve is a main structure with coil and moving iron core, often be generally open, control mode such as normally closed, self-sustaining, long-term energising, power consumption is big, temperature rise, the easy burn-out coil is difficult to adapt to the supporting requirement of gas meter and water meter, has also influenced the exploitation and the use of magnetic card (intelligence) formula gas meter and water meter.

The purpose of this utility model provide a kind of can with intellectual gas meter, the matching used novel solenoid valve of water meter.

The utility model is a low power consumption low voltage energy-saving electromagnetic valve, mainly is made of valve body (8) and valve gap (11), is provided with field coil (5) in the valve gap (11), and secured core (10) and moving iron core (9) also are provided with magnet steel (3) simultaneously under field coil.It is right to use, and when the instantaneous energising of field coil (5), moving iron core (9) rises and contact secured core (10) under the effect of electromagnetic force, and at this moment, the position of moving iron core is kept by the magnetic force absorption of magnet (3), makes valve be opening state; When need are closed, carry out instantaneous energising for back current of field coil, make N, the S utmost point generation conversion of field coil, according to principle of same-sex repulsion, magnet steel loses suction to moving iron core, makes iron core fall to sealing valve port under deadweight and spring (4) effect.

Based on above-mentioned solenoid valve principle, the utility model provides respectively and gas meter and the supporting valve body structure of water meter: the valve body (8) that is used for gas meter is mainly by gas-entered passageway (1), outlet passageway (6), place isolating film (2) and sealing gasket formations such as (7) between the inlet, outlet passage, isolating film and sealing gasket are fixed in moving iron core (9) bottom, and the inner ring of isolating film also can be designed to the compartment concaveconvex structure; The valve body that is used for water meter is mainly by intake tunnel (1), and exhalant canal (6) places water-in and water-out passage top by pressure release passage (16), balance channel (12), the formations such as leading type structure that seal membrane (13) is formed.

The utility model compared with prior art has following good effect and outstanding advantage:

1, adopts the structural design of single field coil and magnet steel and usefulness, pass to forward and reverse instantaneous Weak current, can realize the keying function of valve, it drives valve, close valve required current"on"time very short (general instantaneous current"on"time≤0.1 second), operating voltage also lower (6V), greatly reduce energy consumption, realized the designing requirement of low power consumption, low voltage; The utility model can with magnetic card (intelligence) formula gas meter and the supporting use of water meter.

2, the setting of gas meter electromagnetic valve isolating film, both avoided the erosion of impurity such as the ash that may contain in the coal gas, moisture content, sulphur, benzene, tar to moving iron core etc., improved the sensitivity of driving valve, closing valve again, be used with moving iron core, can under small transient current effect, guarantee the sealing of solenoid valve and open the valve ability.The concaveconvex structure of isolating film design is simultaneously tempered toughness with gentleness, and can make the thin concave surface servo-actuated iron core of diaphragm carry out axial displacement, and thicker convex surface then guarantees not produce radially deformation under the gas pressure effect.

3, water meter can (under 0.1～0.5MPa) effect, make the transient current of low power consumption, open and close solenoid valve smoothly by the leading type structure with the setting of solenoid valve leading type structure in higher hydraulic pressure.

Accompanying drawing has been born structural representation of the present utility model.

Fig. 1 is the opening state schematic representation of gas meter described in the utility model with valve;

Fig. 2 is the closed condition schematic representation of gas meter described in the utility model with valve;

Fig. 3 is the opening state schematic representation of water meter described in the utility model with valve;

Fig. 4 is the closed condition schematic representation of water meter described in the utility model with valve.

Below be that example is further described the utility model with the water meter solenoid valve:

When the instantaneous forward of field coil (5) is switched on, moving iron core (9) rises and contacts secured core (10), and by the suction holding position of magnet steel (3), open the pilot valve mouth (14) that connects pressure release passage (16) and balance channel (12) this moment earlier, pressure medium in the balance channel is arranged to exhalant canal (6) by pressure release passage (16), make seal membrane (13) top form the area of low pressure, pressure medium in the intake tunnel (1) utilizes diaphragm pressure reduction up and down, make diaphragm deformation, on move, open primary valve, when closing, give reverse transient current of field coil, magnet steel loses suction to moving iron core, and moving iron core falls under spring (4) and deadweight effect, in advance the confined bed valve port, this moment, pressure release passage and balance channel were not communicated with, pressure medium by balance channel acts on the seal membrane, seal membrane is restored under the effect of pressure medium and spring (15) move down, and seals primary valve.
