The present invention relates to an air valve using a magnetic coil, and more particularly, when the magnetic coil installed on the valve body is energized momentarily, the plunger inside the coil moves downward to form a flow path so that compressed air that has entered the valve body is formed. When the piston enters the hollow of the left and right pistons via the air flow path and both pistons start to move toward the center of the cylinder, one of the pistons moves faster than the other piston due to the pressure difference already formed in the left and right of the cylinder. And a switching operation for moving the cylinder in a right or left direction, wherein compressed air is discharged through a left or right outlet according to the switching operation. .

Among the air valves using magnetic coils, in the case of a valve mainly used for a vehicle, a magnetic coil is provided in one valve body in order to switch and output air introduced through a single inlet to two outlets. In this case, one NORMAL-OPEN valve and one NORMAL-CLOSE valve were used in combination.

A conventional air valve equipped with two magnetic coils as described above operates in such a manner that each magnetic valve controls the open or closed states of the corresponding air outlets to be opposite to each other. In other words, when one air outlet is opened, the other air outlet is closed. This method requires continuous application of electromotive force since each magnetic valve must be operated continuously for opening or closing. do.

The continuous energization state of the magnetic coil not only causes battery discharge (when the power source is a battery), but also heat generation of the magnetic coil causes the packing members to easily deteriorate and deteriorate, thereby reducing airtightness due to wear. The durability of the valve itself is reduced and in severe cases there was a problem leading to the vehicle fire.

In addition, at least two magnetic coils must be mounted on the valve body, which not only complicates the structure of the valve, but also installs the anti-shock valve in a separate location separate from the valve body, which makes the piping complicated and increases the number of working points due to the large number of fastening points. And there is a concern that the air leakage is high, there is a limit to miniaturization of the valve, the productivity is lowered and the cost is increased.

The present invention was devised to solve the conventional problems as described above, using only one magnetic coil to switch the compressed air flowing through one inlet to two outlets, the magnetic coil is instantaneous Magnetic coil that improves airtightness and durability by reducing the heat generation of the valve by energizing only it and energizing the industrial valve by modularizing the anti-shock valve and check valve in the air valve body. There is a technical problem to provide a configuration of the instantaneous energizing air valve using.

According to the configuration of the present invention for achieving the above object, when the magnetic coil installed on the top of the valve body is momentarily energized, the plunger inside the coil moves downward to form a flow path and the compressed air that has entered the valve body is an air flow path. When the piston enters the hollow of the left and right pistons, and both pistons start to move toward the center of the cylinder, the piston is moved faster than the other piston due to the pressure difference already formed in the left and right of the cylinder. The switching operation to move the right or left direction, characterized in that the compressed air is discharged through the left or right outlet in accordance with the switching operation.

One end of the left piston 40 and the right piston 41 is formed with a cylindrical left piston head 42 and a right piston head 43 of a size that can be inserted into the chambers 31 and 32, and the other end is a chamber ( Left / right piston flanges 44 and 45 are formed with diameters greater than the opening diameters of 31 and 32. In addition, a left piston hollow 46 and a right piston hollow 47 extending from the piston flanges 44 and 45 to the piston heads 42 and 43 are formed inside the left piston 40 and the right piston 41. It is.

The magnetic coil unit 20 is a magnetic field is generated around the coil at the moment when electricity is energized, and the iron core located at the center of the coil is moved by the magnetic force to open a flow path for compressed air to flow into the valve body.

That is, although the compressed air introduced into the second inflow path 95 through the inlet S is usually acted on the bottom surface of the check valve sealing member 83 to block the first inflow path 84 more strongly. In the event of an emergency such as a fire, an emergency valve (not shown) installed between the compressor (not shown) and the inlet (S) is opened to allow manual operation by human force, thereby waiting for compressed air in the air line. To release the first inflow path 84 for easier and faster discharge of air into the inlet S without passing through the anti-shock valve 90 described below. As a valve that performs a function, the first inflow path 84 and the second inflow path 95 are installed at vertical intersections.

Hereinafter, the momentary energizing air valve action using the present invention magnetic coil configured as described above will be described in detail with reference to the drawings.

First, FIG. 4 is a cross-sectional view and a partially enlarged view of the right-side switching start state of the cylinder, and FIG. 5 is a cross-sectional view and a partial enlarged view when outputted to the left outlet C1 by the switching operation shown in FIG. The rightward switching operation of the invention air valve will be described.

As shown in FIG. 4, when electromotive force is applied to the electrode 26 of the magnetic coil unit 20, the magnetized magnetic core 24 pulls the plunger 21 downward, and the plunger 21 descends. Guide pins 70 connected to the lower portion is lowered together with the plunger 21. Then, the descending end of the guide pin 70 presses the pin base 71, and the guide tube 74 attached to the end of the pin base 71 is connected to the spacer entry hole 37 of the center spacer 35. It will enter inside.

Then, the air filled in the right chamber 31 is introduced into the air flow path 50 through the guide tube 74 entered into the spacer entrance hole 37, and the introduced air flows into the air flow path 50. It moves along and flows into the left piston hollow 46 and the right piston hollow 47, respectively.

At this time, even if the same amount of air flows into the hollows 46 and 47 of the left and right pistons, the air is not introduced into the left chamber 32, and the air is introduced into the right chamber 31, so both pistons are the same. Compressed air is filled even when pushing into the chamber by force, and the left piston (40) without compressed air is faster and stronger than the right piston (41), which is forced to receive resistance in the direction of piston travel. The piston flange 44 surface strikes the opening surface of the cylinder 30 as it moves, and by this force the cylinder 30 instantly moves to the right.

As described above, when the switching operation (right switching) is performed in which the cylinder 30 moves in the right direction, the air introduced along the first inflow path 84 passes through the spacer outlet 37 of the center spacer 35. Inflow to the outlet 36 of the left chamber 32 of the 30 is output to the left outlet (C1). At this time, the air remaining in the right chamber 31 before the right direction switching operation is exhausted to the right exhaust port E2 through the outlet 36 of the right chamber 31.

Next, FIG. 6 is a cross-sectional view and a partially enlarged view of the left switching start state of the cylinder, and FIG. 7 is a cross-sectional view and a partial enlarged view when the right outlet C2 is output by the switching operation shown in FIG. A leftward switching operation of the air valve of the present invention will be described with reference to the drawings.

When the electromotive force is applied to the electrode 26 of the magnetic coil unit 20 again while the air is discharged through the left outlet C1 during the right-side switching operation of the cylinder 30, the plunger as shown in FIG. 6. The guide tube 74 attached to the distal end of the pin base 71 enters the inside of the spacer entrance hole 37 of the center spacer 35 by lowering the 21.

Then, the air flow path 50 through the guide pipe 74 introduced from the inlet S and filled in the left chamber 31 through the chamber entrance hole 36 enters the spacer entrance hole 37. ) Flows into the left piston hollow 46 and the right piston hollow 47 of the left piston 40 and the right piston 41 by moving along the air flow path 50.

Then, the right piston 41 is moved to the left side by the pressure of the compressed air introduced into the right piston hollow 47, and at this time, the piston flange 45 of the right piston 41 is moved to the left side of the right piston 41. ) Strikes the opening surface of the cylinder 30, the cylinder 30 is instantaneously moved to the left by this striking force, and the air introduced along the first inflow path 84 is The air is introduced into the outlet 36 of the right chamber 31 through the spacer outlet 37, and the air introduced into the right chamber 31 is output to the right outlet C2. At this time, air remaining in the left chamber 32 before the leftward switching operation is exhausted to the left exhaust port E1 through the outlet port 36. This is the same principle as in the above-mentioned right movement of the cylinder.

Therefore, in the instantaneous energized air valve of the present invention, the air introduced into the left chamber 30 or the right chamber 31 is supplied to the left outlet C1 or the left chamber 30 according to the switching operation in the left and right directions of the cylinder 30 as described above. It is discharged to the right outlet C2.

On the other hand, when the push button 27 for manual operation in the upper portion of the valve is pressed, the plunger 21 is lowered and the guide pin 70 is lowered in the same way as when the magnetic coil is magnetized, so that the electrode 26 Even if no electromotive force is applied, the switching operation of the cylinder 30 can be manually operated.

Next, the operation of the check valve 80 and the anti-shock valve 90 of the air valve of the present invention will be described with reference to FIGS. 2A and 2B. In the present invention, the check valve 80 functions to open and close the first inflow path 84 according to the air pressure of the valve body 10 and the second inflow path 95 and the elasticity of the spring 81, and anti The shock valve 90 serves to prevent the air from rapidly entering the valve body 10 from the inlet S.

FIG. 2A is a sectional view and a partial enlarged view when the check valve is closed and the antishock valve is opened, and FIG. 2B is a sectional view and a partial enlarged view when the check valve is opened and the antishock valve is closed.

First, as shown in FIG. 2A, in a condition in which air in the left and right chambers 30 and 31 is completely exhausted, the check valve sealing member 83 in the first inflow path 84 is removed from the chambers 30 and 31. Since the pressure does not act to close the first inflow path 84 by the elastic force of the check valve spring 81, when the air flows into the air inlet (S) in this state the second inflow path (95) Air flows into the first inflow path 84 through the anti-shock valve orifice 94 of the fine diameter formed in the anti-shock valve piston 93 by moving toward the anti-shock valve plug 91, and as time passes When the air pressure in the first inflow path 84 increases and finally exceeds the elastic force of the anti-shock valve spring 92, the first inflow through the anti-shock valve air inlet 96 formed while pushing the anti-shock valve piston 93 The air supply to the furnace 84 is made.

The following describes the operation of the check valve 80 for releasing compressed air that is filled inside the air valve 1 by the operation of the emergency valve (not shown) in an emergency. The check valve 80 is operated according to the pressure change of the air flowing into the first inflow path 84 and the second inflow path 95.

That is, normally, the compressed air introduced into the second inflow path 5 through the inlet S acts on the bottom surface of the check valve sealing member 83, thereby blocking the first inflow path 84 more strongly. Compressed air in the air line by opening an emergency valve (not shown) installed between the compressor (not shown) and the inlet (S) to enable manual operation of the device by human force in case of an emergency such as a fire. Is discharged into the atmosphere, the atmospheric pressure is on the inlet (S) side, and the pressure inside the valve is high due to the compressed air that has already entered, so the air in the valve pushes out the anti-shock valve piston (93) and checks whether it is released. The valve sealing member 83 must be pushed out and discharged. The check valve spring 81 is much weaker than that of the anti-shock valve spring 92, so that the check valve is not passed through the anti-shock valve 90. It pushes the seal member 83 quickly towards the inlet (S) via the second inlet (95) is released to the atmosphere.

The effect of the present invention configured as described above is different from the combination of the two magnetic valves NORMAL CLOSE type and NORMAL OPEN type by the conventional continuous electric input signal, the use of only one magnetic coil part, By integrating / modifying the check valve and anti-shock valve in one valve body, the air piping is simplified and the tightening points are reduced, which reduces the labor time at the production site, improves the installation, and reduces the risk of air leakage. Compared to the technology, the magnetic valve occupies a compact space.

In addition, since the air flow is switched by using an instantaneous electric signal, it is possible to prevent the problem of battery discharge caused by continuous energization and the possibility of fire due to heat generation and valve confidentiality due to component deterioration. It is an advanced invention that has the effect of improving component durability and reliability, and significantly extending the service life.
