Description

Valve assembly {VALVE ASSEMBLY}

The present invention relates to a valve assembly, and more particularly, to a valve assembly for delivering gas or liquid provided from a source to a storage container.

In general, a water purifier is a device that allows foreign substances contained in external raw water to be filtered and consumed. In recent years, interest in drinking healthy water has risen beyond simply drinking filtered water.

Particularly, as the effect of carbonated water becomes known, various companies have launched a carbonated water producing device in which carbon dioxide gas is injected into a container filled with water.

This carbonated water producing apparatus produces carbonated water in such a manner that carbonic acid gas is supplied from a carbonic acid gas pressure vessel into which carbon dioxide gas is compressed and stored.

However, in the case of the existing carbonated water producing apparatus, carbon dioxide gas is provided solely, and the drinking water must be secured first through a separate water purifier.

Further, there is a problem that when the carbonic acid gas is supplied, the pressure inside the storage container rises excessively, which is also vulnerable to a safety problem.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a valve assembly designed to safely supply a gas and a liquid through one equipment.

According to the present invention, the above object can be accomplished by the provision of a storage container comprising: a body portion having a mounting groove formed therein for mounting the storage container; A liquid port provided in the body portion and connected to a liquid supply source; A gas port provided in the body portion and connected to a gas supply source; A take-out nozzle connected to the body portion to form a hollow to supply a gas provided from the gas port to the storage container side, the liquid being supplied from the liquid port along the outer circumferential surface; And a pressure regulator for regulating a pressure in the storage container.

The body portion may be provided with a liquid flow path for guiding the liquid supplied from the liquid port to the outer surface side of the takeout nozzle.

One end of the gas port may be connected to the gas supply source, and the other end may be coupled to the blowout nozzle.

The pressure regulating unit may include a valve body defining an exhaust passage communicating the liquid flow path with the outside air so that gas in the storage container is exhausted to the outside through the liquid flow path; A switching valve for shutting off gas exhausted through the exhaust passage when gas is supplied through the blowout nozzle and opening the exhaust passage when liquid is supplied through the blowout nozzle; And a control unit for controlling the switching valve.

The pressure regulator may further include an automatic valve for selectively opening the exhaust passage to exhaust gas in the storage container when the pressure in the storage container is equal to or greater than a predetermined value.

The automatic valve may further include: an opening / closing member installed at a position spaced inwardly from a terminating portion of the exhaust passage and opening / closing the exhaust passage; And a first elastic member interposed between the opening and closing member and the end portion of the exhaust passage to press the opening and closing member in a direction opposite to a direction in which the pressure of the gas in the storage container is applied.

Further, the opening and closing member may have a guide groove formed on an outer circumferential surface thereof so that the gas flows along the longitudinal direction.

The pressure regulator may further include a manual valve for exhausting the gas in the storage container to the outside by selectively opening the exhaust passage by a user's operation.

Further, the end of the exhaust passage is formed so that its inner diameter decreases toward the outside, and the manual valve includes: a valve pin mounted on an end portion of the exhaust passage; And a second elastic member that applies an elastic force along a direction in which the valve pin is pressed by the inner body of the body such that the valve pin closely contacts the end portion of the exhaust passage.

According to the present invention, there is provided a valve assembly capable of selecting and smoothly supplying a liquid or a gas to a user.

In addition, through the switching valve, it is possible to supply a suitable fluid by controlling whether or not the gas is exhausted from the storage container depending on whether the object to be supplied is a liquid or a gas.

In addition, by automatically adjusting the pressure when the pressure in the storage container increases beyond necessity through the automatic valve, safety accidents can be prevented.

In addition, the pressure of the storage container can be adjusted by operating the manual valve.

FIG. 4 illustrates a cross-section of a pressure regulating portion of the valve assembly of FIG. 1, and FIG. 5 illustrates a cross-sectional view of the valve assembly of FIG. 1 taken along line V - V '.

4 and 5, the pressure regulator 150 is for controlling a pressure change in the storage container B caused by supply of gas or liquid, and includes a valve body 151 and a switch valve 152 A control unit 153, an automatic valve 160, and a manual valve 170.

The valve body 151 has an exhaust passage 10 therein and is installed at a position where the exhaust passage 10 and the liquid passage 112 can communicate with each other. The valve body 151 is branched into a plurality of branches at an end portion mounted on the base portion 111. A switch valve 152, an automatic valve 160 and a manual valve 170, which will be described later,

In addition, the valve body 151 is branched into a plurality of exhaust passages 10 formed therein in correspondence with the branched end. Therefore, the gas in the storage container B after being supplied can be exhausted to the outside through the exhaust passage 10 which branches into a plurality of liquids via the liquid flow path 112 in the base portion 111. However, the opening and closing structure of the exhaust passage 10 will be described later.

The switching valve 152 is mounted on any one of the branched ends of the valve body 151 to selectively open or close the exhaust passage 10 depending on the kind of fluid supplied to the storage container B to be.

That is, when the liquid supply signal is transmitted from the user, the operation of lowering the pressure by exhausting the gas inside the storage container (B) by opening the exhaust path (10) (10) is cut off so that the supplied gas is prevented from leaking to the outside.

The control unit 153 is connected to the switch valve 152 and transmits a signal from the user to the switch valve 152 to control the switch valve 152. [

The automatic valve 160 is a valve that automatically adjusts the pressure in the storage container B to a predetermined level or less and is installed in any one of the end portions of the valve body 151 And includes a cover member 161, an opening and closing member 162, and a first elastic member 164.

The cover member 161 is coupled to the end portion of the exhaust passage 10 to support a first elastic member 164 to be described later, and a through hole is formed at the center thereof.

The opening and closing member 162 is installed at a position spaced inwardly from the terminating end of the exhaust passage 10 by a predetermined distance and opens and closes the exhaust passage 10 in such a manner that the exhaust passage 10 moves forward and backward along the exhaust passage 10. On the other hand, a stepped step is formed in the exhaust passage 10, and the opening and closing member 162 is pressed by the first elastic member 164 to be described later and is brought into close contact with the stepped step, thereby limiting the movement range.

The opening / closing member 162 includes a front end portion having a relatively small diameter and a rear end portion having a diameter larger than that of the front end portion. The inside of the opening / closing member 162 is recessed to form a space. On the outer circumferential surface of the rear end portion, And is used as a moving path of the gas.

The first elastic member 164 presses the opening and closing member 162 from the cover member 161 and is interposed between the cover member 161 and the opening and closing member 162. On the other hand, the opening and closing timing of the exhaust passage 10 through the automatic valve 160 can be controlled through the elastic force of the first elastic member 164. That is, when it is desired to maintain the internal pressure of the storage container B at a high pressure, it is necessary to use the first elastic member 161 having a large elastic modulus, and to maintain the internal pressure of the storage container B at a relatively low pressure It is preferable to use a first elastic member 161 having a small elastic modulus.

The manual valve 170 is a valve used to exhaust the gas in the storage container B to the outside through the operation of the user unlike the automatic valve 160. The manual valve 170 is mounted on one of the branched ends of the valve body 151 And includes a valve pin (171) and a second elastic member (172).

On the other hand, the exhaust passage (10) of the valve body (151) to which the manual valve (170) is mounted has a shape in which the inner diameter decreases toward the longitudinal end portion.

The valve pin 171 opens and closes the exhaust passage 10 and is pressed by a second elastic member 172 to be described later and brought into close contact with the end of the exhaust passage 10. The valve pin 171 is manufactured to have an outer diameter larger than the inner diameter of the exhaust passage 10 so as not to be released to the outside from the exhaust passage 10, And exposed to the outside.

The second elastic member 172 elastically presses the valve pin 171 to the outside of the exhaust path 10 and is provided between the stepped step formed in the exhaust path 10 and the second elastic member 172 And presses the second elastic member 172 in the outward direction.

Hereinafter, the operation of the valve assembly according to the present embodiment will be described.

First, a storage container (B) into which liquid or gas is to be stored is mounted on the mounting groove (114). The inner space of the storage container B is cut off from the outside in a state of being in close contact with the sealing member 115.

At the same time, when the user operates the predetermined button (not shown) when the user wishes to supply the gas, the switching valve 152 blocks the exhaust passage 10 by the signal transmitted from the control unit 153.

Referring to FIG. 6, after the exhaust passage 10 is blocked by the switching valve 152, And the gas is finally taken out through the hollow of the extraction nozzle 140 connected to the lower end of the gas port 130 into the storage container.

Figure 7 illustrates the gas evacuation operation using the automatic valve of the valve assembly of Figure 1;

Even if the internal pressure is increased due to the gas taken out into the storage container B, the user continuously applies the gas discharge signal or the gas discharge does not stop due to an internal defect or the like, 7, the first elastic member 164 is compressed by a force opposite to the elastic force, and at the same time, the opening and closing member 162 moves in the outward direction.

A space is formed between the opening and closing member 162 and the exhaust passage 10 while the opening and closing member 162 moves and the gas flows along the guide groove 163 formed on the outer peripheral surface of the opening and closing member 162, Exhausted.

That is, when the pressure in the storage container B is high, the opening and closing member 162 opens the exhaust passage 10 and the gas is discharged through the opened exhaust passage 10, .

When the internal pressure of the storage container B is decreased due to the gas discharge, the force applied from the first elastic member 164 becomes greater than the force applied to the opening / closing member 162 due to the gas pressure, Position, shutting off the exhaust passage 10, and stopping gas discharge.

Figure 8 illustrates the gas evacuation operation using the manual valve of the valve assembly of Figure 1;

6, a case where the user intentionally intends to discharge the gas in the storage container B to the outside rather than the operation of discharging the gas through the automatic valve 160 as described above will be described.

A space is formed between the outer surface of the valve pin 171 and the inner surface of the exhaust passage when the user pushes the valve pin 171 directly into the valve body 151 in such a manner that the gas of the storage container B Can be discharged to the outside through the exhaust path (10).

In addition to the manner in which the user directly presses the valve pin 171 to discharge the gas, in conjunction with lifting the storage container B to disengage the storage container B from the body part 110, The gas may be discharged by an indirect pressure method in which the pin 171 contacts a predetermined protruding surface facing the valve pin 171. If the valve pin 171 is pressed in conjunction with the operation of the user, the operation method is not limited.

FIG. 9 is a view showing a state in which liquid is supplied through the valve assembly of FIG. 1; FIG.

The control unit 153 controls the switching valve 152 to open the exhaust passage 10 to stop the supply of the liquid to the storage container B, The internal pressure is reduced to prevent the gas pressure from interfering with the liquid supply.

At the same time, as shown in Fig. 9, the liquid supplied from the liquid port 120 reaches the outer surface of the takeout nozzle 140 through the liquid passage 112 and flows down along the takeout nozzle 140, Is finally supplied to the container (B).

Therefore, according to the present embodiment, a single valve assembly can be used to safely take out liquid or fluid.
