New Description: [New Technology Field] This creation is about a solenoid valve, especially a solenoid valve that must be operated by hand when the voltage is applied. [Prior Art] The solenoid valve uses the attraction force of the electromagnet to open and close the valve, and is used as intermittent control and direction control of fluids such as air, gas, oil, and water. A general solenoid valve is composed of a coil that serves as an electromagnet and a valve that opens and closes a fluid passage. The first figure shows the operation flow of the conventional normally closed solenoid valve. When the current flowing through the coil of the electromagnet, the valve is actuated by the electromagnetic force to open the fluid passage, and when the current is cut off, the valve is closed. Read and interrupt the fluid path. Simply put, the solenoid valve automatically opens and closes the fluid passage by electrically actuating, and the purpose can be achieved without having to use the hand to operate. Automatic control is convenient. However, while the solenoid valve is used to open and close the fluid path, a safer control function is often required. If the conventional electric _ magnetic valve is used as the intermittent control and direction control of the fluid, once the unsafe factor has not been eliminated, the moment when the voltage is applied will be automatically opened due to the solenoid valve, and the result may be very serious. Here, a solenoid valve is used to open and close the gas passage as an example. Assume that the gas grid is in use, because the gas leakage or combustion is incomplete, the gas or carbon monoxide content exceeds the predetermined value and the voltage of the solenoid valve is automatically cut off, so that the solenoid valve is returned to the closed valve position, and the gas passage is stopped. gas. At this time, if the gas crying switch fails to close in time, the solenoid valve cooperates to open the valve position at the moment when the voltage is reapplied, so that the gas switch is maintained at 5 M330396 〇N. As a result, gas (carbon monoxide) poisoning may occur due to gas leakage, or even gas explosion may occur. Λ Therefore, solenoid valves that require a safe start should have a safety device. The so-called safety device is to make the solenoid valve must move in the safe direction. Unless the unsafe factor is manually confirmed, the solenoid will not be automatically opened. [New content] The purpose of this creation is to provide a solenoid valve that can never automatically activate the valve every time the voltage is applied, until the valve is operated by hand, and the fluid passage is opened to control the fluid. More secure. The solenoid valve for realizing the present invention comprises a movable valve portion having a valve body for opening a fluid passage, a third magnetizer at the opposite end of the valve body, and a first spring for holding the valve body in the fluid passage. Positioning portion, a moving portion of the portion, including a second magnetizer, and a second bomb, holding the first magnetizer at a position away from the first magnetizer; and a coil for generating electromagnetic 'Set between the first and second magnetizers. When the current t is coiled, the second magnetizer can be turned into an electromagnet, and when the operation is performed by pressing the operation and the magnet is attracted to each other, the operation portion is pushed back to the original position by the elastic force of the first bomb when the hand is separated. At the same time, the valve part and the coil are displaced, so that the belt-乍 is opened and the valve position is opened to open the fluid passage. When the current is cut off, the valve portion is returned to the original position by the elastic force of the first spring due to the loss of the shaft, so that the valve body is closed and the valve position is closed, and the fluid passage is blocked. The solenoid valve also includes an indicator switch that is activated by the movement of the valve portion to indicate the opening and closing state of the solenoid valve. M330396 In addition, the solenoid valve includes a power switch that operates according to the movement of the operation unit: 〇N』“OFF” action to turn on and off the power of a control circuit, and the output end of the control circuit is electrically connected to the coil for supply. The coil generates the current required by the electromagnetic field. The elastic force of the second spring is greater than the elastic force of the first spring, ensuring that when the first and second magnets are attracted to each other, the valve body can be completely opened without being closed due to the elastic restoring force of the first spring. The valve position blocks the fluid path. The technical content and other objects and features of the present invention can be fully understood by referring to the following detailed description of the drawings. [Embodiment] In the second figure, the internal structure of the solenoid valve 1〇 in the normal valve position is shown to explain the technical content of the present creation. The solenoid valve 1 () is composed of a housing = - bracket 30, - valve portion 4, an operating portion 5, a line _, and a cover 7 。. Wherein the shell (four) has a fluid passage 21, the inside of which is formed with a valve, and a threaded joint 25 for connecting a pipe member (not shown) is formed at its inflow port 23 and the outflow port 24, respectively. 26, other types of joints can also be used, not limited by the thread. The housing 20 also provides a platform 27 for the upper portion 3Q and the cover housing 20. The bracket 30 is locked on the casing 2 by a screw (not shown), and a reliable airtightness is formed between the contact faces of the two through the mating pad 28, thereby stopping the fluid (10). The bracket 3 has an opposite first-supporting portion-supporting portion 32'. wherein, the first-cutting-shaft hole 33, the M330396 supports a rod hole 34, and the shaft hole 33 and the rod hole 34 are online. The support valve portion 40 and the operating portion 50 are linearly moved. " The inter-section portion 40 includes a sliding shaft 41 that is slid through the shaft hole of the bracket 3〇 and held by the first holding portion 31, and the outer circumference snare 35' of the sliding shaft 41 can be generated between the contact faces of the sliding shaft 41 and the shaft hole 33. The front end of the valve body 42 is a hole for opening and closing the fluid passage 21 < - the first magnet 43' and has a first spring 44 trapped in the

The operation portion 50 includes a rod 51 passing through the rod hole of the bracket 3 而 to support the second support portion 32 sliding toward the valve portion 40, the head of the mast 51 is enlarged to form a head 52, and has A second magnet 53 is coupled to the trailing end of the mast 51, and a second spring 54 is looped over the mast. The two ends of the second spring 54 are supported by the head of the mast 51 and the second support portion 32 of the bracket 30, respectively. In addition, a button 55 is mounted on the head 52 of the mast 51 and protrudes outside the cover 7 for hand operation. The shape of the second magnetizer 53 is substantially inverted "E,"; the second bomb is also a compression spring that acts as a compressive force to hold the first magnet 53 away from the first guide by its elastic force. The position of the magnet 43 and the elastic force of the first elastic medium 54 are greater than the elastic force of the first magazine 44, and the effect is left to be fixed on the valve portion 40 by the coil 60 described later, and between the first and the first The magnetic flux 8 M330396 between the body 43 and the second magnetic conductor 53 is synchronously moved with the valve portion 40, and is electrically connected to a control circuit (not shown), so that the coil 60 can obtain current from the control circuit to generate the desired When the electromagnetic field 'the opposite current is cut off', the electromagnetic field disappears. The control circuit is disposed on a circuit board (not shown) fixed to the side of the bracket 30 for driving the solenoid valve 10 to be "open" or "closed". The action of the opening action must be coordinated with the manual operation, and the details are also left to be described later. Since the control circuit is not within the scope of this creation, further explanation is not necessary. The creation can also be carried out by the operation unit 50. The power switch 56 is controlled to perform an "ON" "OFF" operation to turn on and off the power supply connected to the control circuit. In the embodiment of the drawing, the power switch uses a push button switch which is disposed at the movement of the button 55. In the path, it can be pressed by the operation button 55 to achieve the purpose of turning on and off the power of the control circuit. This creation can control the operation of the indicator light 40 to perform an "ON" and "OFF" action by the movement of the valve portion 40. An indicator light (not shown) electrically connected to the indicator switch 46 is turned off. In the embodiment of the drawing, the indicator switch 46 uses a micro switch, and its actuating piece 47 is connected by a slip. The connecting rod 45 of the shaft 41 is controlled, and the connecting rod 45 can be pressed down with the movement of the sliding shaft 41 to release the actuating piece 47, so that the a contact of the micro switch is opened and closed, and the control indicator light is turned off. It can be made for the light-emitting diode. The cover 70 is locked on the platform 27 of the housing 20 by screws 29 (see the sixth figure) to protect the bracket 30, the first magnet 43 and the operation unit. 50, coil 60, power switch 56, indicator switch 4 6 and the control circuit components. M330396 The third figure shows the operation flow of the solenoid valve 10, the fourth figure shows the state of the solenoid valve 10 when the button 55 is pressed, and the fifth figure shows the state of the solenoid valve 10 when the hand leaves the button 55. According to the solenoid valve 10 of the present invention, when the button 55 of the operation unit 50 is pressed, the operation unit 50 moves toward the valve unit 40, and the power switch 56 is pressed by the button 55 to turn on the power of the control circuit, so that the slave control circuit A voltage is supplied to the coil 60, causing the coil 60 to generate an electromagnetic field around the current by passing the current, and the second magnetizer 53 in the electromagnetic field becomes an electromagnet and attracts the first magnetizer 43. When the hand leaves the button At 55 o'clock, the entire operating portion 50 is returned to the original position by the elastic force of the second spring 54, and at the same time, the valve portion 40 and the coil 60 are moved to move the valve body 42 to open the valve position to open the fluid passage 21. Since the elastic force of the second spring 54 is greater than the elastic force of the first spring 44, it can be ensured that when the first magnetizer 43 is attracted by the second magnetizer 53, the valve body 42 can be completely opened without the first spring 44. The elastic restoring force returns to the closed valve position, and the fluid passage 21 is blocked. Of course, if the mutual attraction force of the first guide magnet 43 and the second magnet 53 is greater than the elastic force of the first spring 44, the elastic force of the second spring 54 is not necessarily greater than the elastic force of the first spring 44. . On the other hand, when the valve portion 40 is displaced by the electromagnetic force, the link 45 simultaneously presses the actuating piece 47 of the indicator switch 46 so that the a contact is closed, thereby turning on the circuit point connected to the indicator light. The indicator light illuminates a visual signal that the solenoid valve 10 is in the open position. In the case where the solenoid valve 10 is actuated to open the valve position, there are two ways to close it by the M330396. - The species is human, and the species is automatic. Among them: The manual operation is repeated by hand - press the 55 and then release. At this time, the power of the circuit is interrupted due to the power off 56 again. According to this, the coil 60 has two currents, so the valve portion 40 is replaced by the electromagnet. The attraction force disappears and is pushed back to the original position by the elastic force of the first spring 44. The valve body 42 is sealed to the valve seat 22 to block the fluid passage 21, while the operation portion _ is the hand to leave (4) and the second spring 54 is used. The elastic force returns to its original position. The automatic operation is performed by the profit-making circuit (4), and (4) the current of the coil 6 ,, so that the valve portion 40 is returned to the closed valve position by the elastic force of the first spring 43 due to the disappearance of the electromagnetic force, and the fluid passage 21 is blocked. As for the indicator switch 46, whether it is manual control or automatic control, its a contact will open when the valve portion 40 is returned to the original position, and the indicator light is turned off because the actuating piece 47 is released by the link *5. The sixth and seventh figures show the appearance of the solenoid valves 10 mounted to the gas regulator 90 and the gas line 95, respectively. According to this creation, since the solenoid valve has a safety device, the operation of the fluid can be made safer when the voltage is applied, unless the manual operation is performed, and the solenoid valve is not automatically activated. Of course, the above embodiments may be modified without departing from the scope of the present invention. Therefore, all the matters included in the above description and _ are to be regarded as examples, rather than limiting the scope of patent application of the present invention. .
