Abstract
The utility model discloses a self-attracting electromagnetic valve. A static iron core is fastened on the support frame of a valve body, and the exterior of the static iron core is sheathed with a guide pipe. The exterior of the guide pipe is sheathed with a coil and lead-out wires. A moving iron core is arranged in the guide pope, and the moving iron core freely moves in the guide pipe. The other end part of the guide pipe is provided with a sealing rubber cushion, and the neck part of the guide pipe is provided with a corrosion-resistance circular disc-shaped flexible membrane which is hermetically combined with the moving iron core in radial direction. The inner hole of the guide pipe is provided with a spring. The spring is arranged between the working surfaces of the moving iron core and the static iron core. A cover plate is arranged between the flexible diaphragm and the valve cap. As the utility model is provided with the flexible diaphragm, the utility model overcomes the defect that the common self-attracting electromagnetic valve is easily eroded by gas and then the early failure is caused.
Description
The utility model relates to the automatic control electromagnetic valve of a kind of burner, particularly a kind of control self-priming solenoid valve that is used for the fully-automatic household gas instantaneous water heater of gas kinds such as artificial coal gas.
In the full-automatic gas-fired water heater at home, extensively adopt a kind of blast tube control gear at present based on the self-priming solenoid valve.In this plain edition self-priming valve structure, static iron core is fastened on the valve body support, static iron core is with conduit outward, catheter jacket is being adorned coil and lighting outlet, moving iron core is contained in the conduit and can unrestricted motion in conduit, seal rubber pad and pad are equipped with in moving iron core the other end, at pad and valve cover chamber spring are installed.When work, static iron core and moving iron core working surface produce strong suction, against the force of the spring, and moving iron core drives seal rubber pad and shifts to static iron core together, thereby opens blast tube.When off working state, the suction-combining force between static iron core and the moving iron core disappears, and under the effect of spring, seal rubber pad is shifted to the air valve body end face with moving iron core, thereby closes blast tube.In this plain edition self-priming electromagnetic valve structure, moving iron core can rotate and move in conduit, but does not take any protective measure, thereby combustion gas can be entered conduit and is filled in the conduit by the gap of moving iron core and valve gap.And more or less contain corrosive impurity in the artificial coal gas, these corrosive impurities produce corrosion to the iron core working surface and cause the self-priming solenoid valve to lose efficacy, particularly in that the artificial coal gas purified treatment is bad when bringing corrosive impurity content to exceed standard greatly, corrode stronger, it is faster to lose efficacy, cause water heater complete machine infant mortality height, become one of technical barrier of gas industry, hindered shaping up of China's gas industry.
The purpose of this utility model is to overcome above-mentioned self-priming solenoid valve is easily caused early failue by the combustion gas etch critical defect, provide a kind of can prevent the combustion gas etch, can be at the self-priming solenoid valve of the medium-term and long-term reliably working of unholiness combustion gas.
For achieving the above object, the solution that the utility model is taked is: a kind of self-priming solenoid valve, static iron core is fastened on the valve body support, static iron core is with conduit outward, catheter jacket is being adorned coil and lighting outlet, moving iron core is contained in the conduit and can unrestricted motion in conduit, seal rubber pad is equipped with in moving iron core the other end, moving iron core neck is equipped with a corrosion-resistant discoid flexible partition and combines with moving iron core radial seal, in the moving iron core endoporus spring is housed, spring is between moving iron core and static iron core working surface, and flexible partition and valve cover chamber also have a cover plate.
Though the utility model is identical with the working principle of plain edition self-priming solenoid valve, but because when the utility model is in running order, flexible partition is pressed on the air valve body oral area, thereby combustion gas and self-priming solenoid valve internals in the passage are isolated fully, corrosive impurity can not occur the iron core working surface is produced the phenomenon of corrosion, thereby stop water heater complete machine early failue.
Be described in further detail below in conjunction with the good effect of accompanying drawing the utility model and generation thereof.
Fig. 1 is the utility model master pseudosection (gas circuit is closed).
Fig. 2 is the utility model master pseudosection (gas circuit is open-minded).
Fig. 3 is plain edition self-priming solenoid valve master's pseudosection (gas circuit is closed).
Fig. 4 is plain edition self-priming solenoid valve master's pseudosection (gas circuit is open-minded).
The utility model structure as shown in Figure 1.Static iron core (2) is connected on the valve body support (1) by screw, outer suit conduit (3), the outer suit of conduit (3) coil (4) and lighting outlet is arranged and the burner electrical-controller links, moving iron core (6) is packed in the conduit (3), and can unrestricted motion in conduit (3), moving iron core (6) neck is equipped with a corrosion-resistant discoid flexible partition (9) and combines with moving iron core (6) radial seal, and do not influence the unrestricted motion of moving iron core (6) in conduit (3), the endoporus and the outer annulus edge portion of flexible partition (9) are equipped with the ring packing structure, moving iron core (6) end suit seal rubber pad (10), spring (5) is housed in the endoporus, spring (5) has a cover plate (8) between flexible partition (9) and valve gap (7) between moving iron core (6) and static iron core (2) working surface.When combining, the utility model is connected firmly on air valve body with screw with water heater.When off working state, there is not the suction-combining force between static iron core (2) and the moving iron core (6), under the elastic force effect of spring (5), the seal rubber pad (10) on moving iron core (6) end face is pressed on the air valve body end face, and blast tube is closed.When work, static iron core (2) produces strong suction with moving iron core (6) working surface, overcomes the resistance of spring (5), and moving iron core (6) drives seal rubber pad (10) and shifts to static iron core together, has opened blast tube; At this moment, cover plate (8) is pressed on the peripheral seal ring of flexible partition (9) on the air valve body oral area annular sealing surface, and combustion gas can not enter conduit (3).Because the utility model has adopted effective measures to prevent the corrosion of combustion gas to inner iron core working surface, thereby improved the adaptability of self-priming solenoid valve and operational safety, prolonged operating life in the bad combustion gas atmosphere of purified treatment significantly, greatly reduce the rate of fault of automatic fuel gas fast water heater, improved the adaptive capacity of water heater bad source of the gas.
