Description

Automatic Valve {Automatic Valve}

The present invention relates to a valve for opening or blocking a flow of a fluid passing through a pipe, and more particularly, to automatically detect this state, while automatically opening and closing the opening and closing operation of the valve by an external signal. Relates to an automatic valve.

In general, a valve has a valve case interposed in a pipe having a predetermined diameter as a sealing means, and a flow path penetrates through a valve seat therein to prevent a valve cock (this prevents a pipe from which a fluid or gas flows to a predetermined area or completely). Internal flow path is opened and closed by rotation of all valves to be shut off.

Therefore, the valve case is to be matched to the pipe that the inner diameter is continued back and forth, wherein the sealing means is generally used means for interposing the O-ring or seal tape when the female screw is coupled between the pipe and the case, the pipe and valve case The flow rate of the fluid or gas flowing inside is controlled by the opening and closing area according to the rotation of the valve cock. In general, the valve cock (handle) used is the ball with a hole through the bottom of the shaft. This is a ball valve that determines the flow rate (the amount of gas in the case of gas piping, but will also be referred to as the flow rate in the following) depending on how much of the opening of the ball through the communication path.

In addition to the valve device, there is also a configuration in which the valve is operated using a motor as a technique for operating the valve open / closed state and the valve locking device.

However, such a valve is merely a structure that requires no manpower by opening or closing the flow path manually by a motor, and in this case, it is inconvenient to check the on / off state of the valve directly. In addition, when the inside of the pipe is a flammable material such as gas, gas may be ignited by electricity flowing through a motor, which makes it impossible to use the pipe.

The present invention has been made to solve the above-described problems, firstly, while fully automating the opening and closing operation of the valve, so as not to affect any ignition material such as gas flowing therein, and second to easily determine the opening and closing state of the valve To provide an automatic valve.

In order to achieve the above object, the present invention provides a valve case connected to the sealing means by a pipe of a predetermined diameter; A through hole is formed therein and is installed between the first and second bulkheads installed upright in the valve case and between the first and second bulkheads to change magnetic poles of the open magnet and the closed magnet according to the polarity of the power source. A control unit, a mechanism unit for opening and closing sides of the openings and closing magnets of the control unit to prevent the openings of the first and second partitions from being interchanged, and mounted between the first and second partitions, respectively. It is characterized in that the main body is made of a main valve for the main body of the communication between the first bulkhead and the second bulkhead swings the rotor formed with the valve opening by the opening and closing of the sides to communicate or block.

Between the first partition 2 and the second partition 3, between the first partition 2 and the second partition 3, between the first and second partitions 2, 66, and 67. The diaphragm 44 which half-blocks the center and the rotating body 42 in which the valve hole 43 is formed by opening and closing the sides 61, 62, 66, and 67 are swinged to form the first partition 2. It is characterized in that the main valve (4) for communicating or blocking the main through-hole 21, 31 between the second bulkhead (3) Gong.

In the above configuration, the valve shaft (1) in which the supporting shaft 41 is installed in the center of the second partition 3 is extended so that the rotating magnet 54 is mounted, and the anode of the rotating magnet 54 faces. More preferably, characterized in that the proximity sensor 55 is mounted on the outer periphery.

Reference numeral 11 is a connecting portion in which the valve case 1 is connected to the pipe 8, and the connecting portion 11 has a threaded portion formed on an inner circumferential surface or an outer circumferential surface thereof for joining with the pipe 8. When sealing member (O-ring or resin, etc.) is inserted and connected to prevent fluid leakage, the connection can be completely completed.

In addition, reference numeral 11 denotes a connection in which the valve case 1 of the present invention is connected to be sealed when connecting to the pipe 8 which is a conventional pipe, which is a connection between the known pipes 8 and 8. Since the structure is adopted as it is, the illustration is omitted, reference numeral 41 is a support shaft supporting the shaft so that the rotating body 42 is a swing.

Next, the operation of the automatic valve according to the present invention configured as described above will be described.

The valve case 1 of the present invention is a case in which an automatic valve is incorporated, and a device for blocking / opening the flow path is built-in, and the valve case 1 is interposed in a pipe. After installation, it is integrated with the pipe.

In this state, the fluid flowing in the pipe 8 encounters the first first partition 2, and the first partition 2 and the second partition 3 have holes 21, 22, 23, 31 therein. , 32, 33 are formed to be installed upright in the valve case (1), the first fluid through the main through hole 21, the opening hole 22 and the closing hole 23 of the first partition (2) Try to flow. However, the opening hole 21 and the closing hole 22 are opened and closed by the opening side 61 and the closing side 62, these are operated by the mechanism portion 6 to be described later, the main hole 21 is also the main valve ( It will be opened and closed by 4) This will also be described later.

First, the operation of the control unit 5 will be described. The control unit 5 is mounted on the outer circumferential portion of the valve case 1 between the first partition 2 and the second partition 3, and the power source 7 By inducing magnetic interference of the electromagnet 511 and the bar magnet 512 embedded in the accommodating portion 51 according to the polarity of the magnetic pole of the open magnet 52 and the closed magnet 53, that is, in Figure 3b As shown, when one side (upper part of the figure) of the electromagnet 511 is excited to the N pole by an external power source 7, the bar magnet 512 is one side (upper part of the figure; as shown) according to its polarity. When the magnetic pole of the electromagnet 511 is changed at this time, the bar magnet 512 is rotated by 180 ° from one side to the other side (bottom of the figure; dotted line) (the stopper is mounted to limit the rotation), so the bar magnet As the 512 rotates, the cylindrical magnet 514 is rotated by the connecting shaft 513 supporting the bar magnet 512, and the cylindrical magnet ( 514 is a cylindrical body that joins the north pole and the south pole, and the pole is replaced according to the rotation, which gives magnetic field interference to the open magnet 52 and the closed magnet 53 disposed above and below to rotate them. In addition, the opening magnet 52 and the closing magnet 53 are mounted on the outer circumference of the valve case 1, and the opening side 61 and the closing side 62 for closing the opening hole 22 and the closing hole 23, respectively. The tuning magnet 63 is attached to the end thereof, and the side having the tuning magnets 63 and 63 having opposite poles to the valve case 1 of the open magnet 52 and the closing magnet 53, respectively. (61, 62) is closed and the sides 62, 61 having the same pole are opened.

In addition, the mechanism part 6 is formed by the opening magnet 52 and the closing magnet 53 of the control unit 5, as shown in detail in FIG. 4. By opening and closing the sides (61, 62, 66, 67) of the barriers 22, 23, 32, 33, which are respectively interchangeably, the opening holes 22, 32) and the closing holes (23, 33) are located on the opposite side of each other so that the opening side 61 is synchronized with the first close side 66 by the lever action between the connecting (64, 64) and the hinge (65, 65) And the closing edge 62 is tuned to the second close edge 67 (these terms are not limiting and may be interchanged) to open and close the openings 22 and 32 and the closing holes 23 and 33 together. Controlled.

In addition, the main valve 4 is installed between the first partition 2 and the second partition 3, and the diaphragm 44 and half to close halfway between the first partition 2 and the second partition (3) and the By rotating the sides 61, 62, 66, and 67, the rotating body 42 having the valve through-hole 43 is swinged so that the main through-hole 21 between the first and second partitions 2 and 3, 31 is in communication or interruption, and as shown schematically in FIG. 5, the power supply to the control unit 5 is such that the above-mentioned fluid reaches the first partition wall 2 and the opening holes 22 and 32 are opened. When 7 is applied (FIG. 5A state), the closing holes 23 and 33 are closed by the action of the mechanism part 6, and at this time, the fluid passing through the opening hole 22 of the first partition 2 is The diaphragm 44 and the rotating body 42 cannot be passed to the opening hole 32 side of the second partition wall 3, and the closing hole 33 of the second partition wall 3 is in a closed state. 3) the pressure is raised in a closed chamber composed of the diaphragm 44 and the rotating body 42 When the pressure is greater than a predetermined pressure, the rotary body 42 is pushed out (a direction of FIG. 5A). At this time, the closed chamber formed on the opposite side of the closed chamber may communicate with the second partition wall even though fluid is filled therein Since the opening hole 32 of 3) is in an open state, the fluid flows out without resistance into the opening hole 32 of the second partition 3 as the rotor 42 is pushed, so that the rotor 42 swings. Thus, between the main through holes 21 and 31 of the first and second bulkheads 2 and 3, the valve through hole 43 of the rotating body 42 is in communication (FIG. 5B). Most of the fluid flows through the main through holes 21 and 31 from the moment of approaching this state, and the main through holes 21 and 31 become larger in diameter than the open holes 22 and 32 so that the pressure of the closed chamber is gradually reduced. However, the pressure of the closed chamber can no longer push the rotor 42 in the state of complete communication. When the pressure of the closed chamber decreases due to a manufacturing problem or a design error, the stopper (at the swing end of the rotor 42) 45) may be a solution.

When the pole of the electromagnet 511 is replaced by changing the power supply 7 supplied to the control part 5 in the said open state, the control part 5 and the mechanism part 6 open the opening hole 22 and 32 by the above-mentioned adverse reaction. ) And the closing holes 23 and 33 are reversely closed / opened, which increases the pressure of the closed chamber in communication with the opening hole 32 (which is closed in this state) of the second bulkhead 3. 42) is pushed to the opposite side (b direction in the action state diagram of Figure 5c) between the main through-hole 21, 31 is gradually blocked by the body of the rotor 42 is completely blocked in the state of Figure 5d . Of course, even at this time, by installing the stopper 45 at the swing end of the rotating body 42, it is possible to block further unnecessary swing.

According to another configuration of the present invention, in addition to the above-described configuration, the support shaft 4 installed in the center of the second partition 3 is extended so that the rotating magnet 54 is mounted thereon, and the rotating magnet 54 Added a configuration in which the proximity sensor 55 is mounted on the outer circumference of the valve case 1 facing the anode, which changes the distance between the magnetic pole of the rotating magnet 54 and the proximity sensor 55 as the support shaft 41 rotates. Therefore, it is prepared to sense the deformed magnetic field between them and use it as the data for judging the opening and closing of the entire valve, and by combining the sensed data and the operator's intention of operation (for example, changing the pole of the power supply) It can also be manufactured as a fully automatic valve by providing a central processing unit for processing, this additional configuration is omitted because it is an improved invention using the present invention.

As described above, the automatic valve according to the present invention can easily control the on / off state of the valve from the outside, and it is possible to easily switch the operating state of the valve easily, so that a simple and safe operation of the valve can be performed.

In addition, the facility is simple and can be used not only to simply transfer the gas but also in the transfer of the liquid can be used in various applications regardless of the place of use.

In particular, when used in gas pipes, the power is not applied at all in the pipe so as to be suitable for the safe use of the gas, since only the action by magnetic force is made, there is a convenient and economical advantage to block ignition at the source.
