CN-121993647-A - Non-pressure electromagnetic valve structure

Abstract

The invention discloses a non-pressure electromagnetic valve structure, which comprises a valve body and a coil positioned at the upper end of the valve body, wherein the valve body is provided with a water inlet and a water outlet, and a valve port communicated with the water inlet and the water outlet is arranged in the valve body. The electromagnetic valve is closed instantly under the action of strong spring force after power is off, the sealing diaphragm is firmly pressed down and attached to the valve port by the strong spring force, the sealing performance is very reliable, and small particle impurities or foreign matters such as scale can be wrapped in the sealing diaphragm due to good ductility of the sealing diaphragm, so that the situation of water leakage cannot occur.

Description

Non-pressure electromagnetic valve structure Technical Field The invention relates to an electromagnetic valve, in particular to a non-pressure electromagnetic valve structure. Background The electromagnetic valve is used as an automatic executing component and has the characteristics of flexible action, automatic control after being matched with software, energy conservation and environmental protection. The electromagnetic valve is distinguished according to the opening water pressure, and can be divided into a non-pressure valve (opening water pressure is 0-0.08 Mpa), a normal pressure valve (0.02-0.8 Mpa) and a high-low water pressure universal valve (0-1.0 Mpa), wherein the non-pressure valve and the high-low water pressure universal valve existing in the market at present have the defects of the self-pressure valve, the non-pressure valve is low in power consumption because of being required by low power consumption, the spring force value used in the non-pressure valve is small, the situation that the requirement on water quality is too high, the electromagnetic valve is sensitive to impurities and is not tight in sealing easily occurs in the using process, the service life is short in the using process, the fault rate is high, the high-low water pressure universal electromagnetic valve adopts a straight-through structure, the force value of a compression sealing spring is increased, but the coil power is high, the cost is not economical, the automatic control circuit board cannot provide too large overload power, the automatic control is not facilitated, and other structures can also realize the situation that the low power consumption and the water yield is always too low under the low water pressure condition to meet the actual using requirement, and the market. Disclosure of Invention In view of the above-described drawbacks of the prior art, an object of the present invention is to provide a non-pressure solenoid valve structure. The technical scheme is that the non-pressure electromagnetic valve structure comprises a valve body and a coil positioned at the upper end of the valve body, wherein the valve body is provided with a water inlet and a water outlet, a valve port communicated with the water inlet and the water outlet is arranged in the valve body, a valve sleeve is arranged in the coil, the lower end of the valve sleeve is opened and extends into a movable iron core, the lower end of the movable iron core is connected with a sealing diaphragm for blocking the valve port, a spring extending up and down is arranged between the upper end of the movable iron core and the inner wall of the upper end of the valve sleeve, and a reinforcing screw is screwed in the upper end of the valve sleeve. Further, a concave hole is arranged at the upper end of the movable iron core, the middle lower part of the spring stretches into the concave hole, and the top of the spring is abutted against the inner wall of the upper end of the valve sleeve. Further, the sealing surface of the lower end of the sealing membrane, which is contacted with the valve port, is recessed upwards. Further, the coil housing is provided with a U-shaped iron support, a spring pad is arranged in the middle of the top of the U-shaped iron support, and the reinforcing screw penetrates through the spring pad and the U-shaped iron support from top to bottom and then is screwed with the upper end of the valve sleeve. The non-pressure electromagnetic valve structure has the advantages that the movable iron core is powerful when the electromagnetic valve is electrified, the electromagnetic valve is quickly started to be opened, the water yield is high, the electromagnetic valve is closed instantly under the action of powerful spring force after the power is off, the sealing diaphragm is firmly pressed down and attached to the valve port by the powerful spring force, the sealing performance is very reliable, and small particle impurities or foreign matters such as scale can be wrapped in the sealing diaphragm due to good ductility, so that the situation of water leakage cannot occur.
