Description

VAPORIZER FOR PREVENTING LIQUID FROM FLOWING OUT}

The present invention relates to a liquid leakage preventing device vaporizer, and more particularly, a liquid leakage prevention device that can be supplied smoothly only in the vaporized state of the gas supplied from the large gas storage tank in which LPG and the like is discharged without being discharged. It is about a carburetor.

In general, liquefied petroleum gas stored in the storage tank is stored in the liquid state.

Therefore, when liquefied petroleum gas of the storage tank is supplied to users in a liquid state, it is very dangerous, so the liquid gas must be changed to a vaporized state to supply the gas to be safely used.

If the liquefied petroleum gas is supplied in a liquid state, there is a problem in that the gas pressure rises, causing the gas pipe or the valves installed in the middle to burst or break.

In order to prevent the above problems, as shown in FIG. 1, the vaporizer 3 is installed in the middle to forcibly vaporize and supply the liquefied petroleum gas supplied from the storage tank 1 stored in the liquid state.

Therefore, conventionally, direct heating and indirect heating vaporizers are used, and indirect heating type has been generally used.

The indirect heating type heats the water or the antifreeze and vaporizes the gas, so when the temperature rises above a certain temperature, there is an advantage that the temperature does not rise anymore. Since scale is generated inside, it not only reduces efficiency, but also needs to periodically perform a process for removing scales stuck in the carburetor, and regularly replenishes water, etc. The buoyancy type liquid leakage preventer blocked the gas supply passage so that no gas was supplied and it was very difficult to release it.

Accordingly, the present invention has been made in view of the same problems as in the prior art, and an object of the present invention is to vaporize liquefied petroleum gas in a direct heat manner, so that the gas supplied from a large gas storage tank in which LPG is stored does not become a liquid state and vaporizes. Provided is a liquid leakage prevention device vaporizer that can be supplied in a smooth state.

The configuration of the liquid leakage preventing device vaporizer of the present invention will be described in more detail below.

Liquid leakage preventing device vaporizer of the present invention, the liquid level adjusting portion (2) is formed in a cylindrical shape in the longitudinal direction in the inner center, the outer circumferential surface thereof is the length of the heat exchange piece (12) in order to discharge heat and heat exchange Heat transfer portion 13 formed in a plurality in the direction is formed.

The cover 9 is formed to surround the heat exchange piece 12 formed on the outer circumferential surface of the heating transmission part 13 to form a gas vaporization moving part 30 capable of moving the introduced liquefied petroleum gas to the upper side in the longitudinal direction. Is fitted and fixed.

A liquefied petroleum gas supply valve unit such that liquefied petroleum gas is injected from the liquefied petroleum gas storage tank to the lower side of the vaporizer to supply gas to the liquid level adjusting unit 2 formed in the longitudinal direction in the center of the heating transmission unit 13 ( 6) is formed.

In addition, a gas discharge valve 34 is formed on the upper side of the vaporizer of the present invention so that the liquefied petroleum gas passing through the liquid level adjusting unit 2 is discharged in a vaporized state.

Between the liquid level adjusting part 2 and the liquefied petroleum gas supply valve part 6, a liquid stagnation part 16 is formed to lower the level of the liquefied petroleum gas introduced therein, and the liquid level adjusting part 2 and the gas discharge are provided. The discharge side gas stagnation part 40 is formed between the valve part 34 and so that the water level of the gas supplied may not become high.

In addition, the gas supplied is introduced through the lower side of the liquid level adjusting unit 2, and the gas introduced into the lower side of the liquid level adjusting unit 2 is a gas vaporization moving unit formed in the longitudinal direction on the outer circumferential surface side of the heating transfer unit 13. Upper and lower flow paths 50 and 32 are formed along the 30 so as to flow into the upper side of the liquid level adjusting unit 2 again.

The upper and lower flow paths 50 and 32 which connect the liquid level adjusting unit 2 and the gas vaporization moving unit 30 formed on the outer circumferential surface of the liquid level adjusting unit 2 are formed of the liquid level adjusting unit 2. On the lower side, a plurality of lower passages 50 are formed along the outer circumferential surface of the liquid level adjusting unit 2, and a plurality of upper passages 32 are formed on the upper side along the outer circumferential surface.

The liquefied petroleum gas flowing into the liquefied petroleum gas supply valve part 6 is supplied to the liquid level adjusting part 2 via the gas vaporization moving part 30 without being directly discharged to the gas discharge valve part 34 or the liquid level adjusting part. The buoyancy liquid spill prevention device 20 is formed to be movable up and down to move on the inner circumferential surface of (2).

Moreover, on the liquid level adjusting part 2 which has the gas vaporization moving part 30 and the buoyancy type liquid outflow prevention apparatus 20, the liquefied petroleum gas which flows along the longitudinal outer peripheral surface is filled up to about 2/3, and is vaporized.

The liquid level adjusting unit 2 is formed longer than the buoyancy type liquid leakage preventing device 20 so that the buoyancy type liquid leakage preventing device 20 is lowered by the amount of liquefied petroleum gas introduced thereto.

In addition, when liquefied petroleum gas is suddenly supplied to the liquefied petroleum gas supply valve part 6, the lower side liquid outflow prevention valve part 10 is formed so that the excessively supplied liquefied petroleum gas no longer flows into the liquid level adjusting part 2. do.

In addition, the upper side of the buoyancy liquid leakage prevention device 20 in order to block the liquefied petroleum gas excessively passed through the lower side liquid leakage prevention valve portion 10 by the instantaneously supplied liquefied petroleum gas The liquid leakage prevention valve part 4 is formed.

An outer circumferential surface is formed in a trapezoidal shape so that the lower side liquid leakage preventing valve part 10 formed on the lower side of the buoyancy type liquid leakage preventing device 20 is blocked while being raised.

In addition, the lower side liquid leakage prevention valve unit 10 is fixed to the lower guide rod 60 so as to operate elastically along the lower guide rod 60 formed on the lower side of the buoyancy liquid leakage prevention device 20 The lower side liquid leakage preventing valve part 10 is pushed by the spring 8 formed integrally with the ring 14.

In addition, the hemispherical concave portion 42 is formed on the lower side of the buoyancy type liquid leakage preventing device 20 to increase the buoyancy force which is increased by the amount of liquefied petroleum gas introduced into the liquid level adjusting unit 2 and the overpressure. Is formed.

The upper side liquid leakage preventing valve part 4 of the buoyancy type liquid leakage preventing device 20 is lifted to the upper side of the liquid level adjusting part 2 and opens the outlet 24 communicated with the discharge side gas stagnation part 40. The convex surface is formed to block, and the upper guide rod 62 is formed so that the buoyancy liquid leakage preventing device 20 is guided without shaking in the longitudinal direction.

Due to the increase in pressure caused by the oversupply of liquefied petroleum gas to the liquid level adjusting unit 2, the upper liquid leakage preventing valve unit 4 is operated so that the liquefied petroleum gas of the liquid level adjusting unit 2 is not supplied continuously. When stopped, a pressure release valve part 22 is formed to block and release the hole 38 formed to discharge the pressure of the liquid level adjusting part 2 to the discharge side gas stagnation part 40 to release it.

With reference to the accompanying drawings, the liquid leakage prevention apparatus vaporizer of the present invention configured as described above will be described in detail the operating state as follows.

Figure 2 is a view showing the liquid leakage preventing device vaporizer of the present invention, Figure 3 is a view showing the A`-A cross-sectional view shown in Figure 2, Figure 4 is a view showing the operating state of the liquid leakage preventing device vaporizer of the present invention 5 is a view showing a state in which the lower side liquid leakage prevention valve portion of the liquid leakage preventing device vaporizer of the present invention is operated, Figure 6 shows the operating state of the bypass valve portion of the liquid leakage preventing device vaporizer of the present invention. 7 is a view showing a separated perspective view of the liquid leakage preventing device vaporizer of the present invention, Figure 8 is a view showing a modification of the liquid leakage preventing device vaporizer of the present invention.

The vaporizer of the present invention converts the liquefied petroleum gas stored in the liquid storage tank into a gas having an appropriate pressure in a gaseous state instead of a liquid state to the user.

The vaporizer of the present invention, when the liquefied petroleum gas supply valve part 6 of the vaporizer is gradually opened in order to introduce the liquefied petroleum gas stored in the liquid storage tank, the liquefied petroleum gas is liquefied petroleum gas supply valve part 6 as shown in FIG. It flows into the inlet side liquid stagnation part 16 via the process.

The liquefied petroleum gas introduced into the inlet liquid stagnation part 16 is moved while being filled up with the upper liquid level adjusting part 2.

At this time, the heater 18 of the heating transmission unit 13 formed inside the vaporizer is normally operated to maintain a constant temperature inside.

Accordingly, the liquefied petroleum gas flowing into the liquid level adjusting unit 2 is supplied to the liquid level adjusting unit 2 and the buoyancy type liquid leakage preventing device 20 by the buoyancy type liquid leakage preventing device 20 installed in the liquid level adjusting unit 2. The liquefied petroleum gas, which is moved in the longitudinal direction between 20 and the other, flows along the lower flow path 50 penetrated to the outer circumferential side on the lower side by the buoyancy type liquid leakage preventing device 20 of the liquid level adjusting unit 2. It is moved while being filled with the gas vaporization moving part 30.

By the temperature of the heater 18, the liquefied petroleum gas filled in the liquid level adjusting unit 2 in about 2/3 is vaporized and moved along the gas vaporization moving part 30.

At this time, since the heater 18 temperature of the carburetor in operation is automatically adjusted to maintain the proper temperature by a thermostat (not shown) or the like, when the temperature is increased, the high temperature cut-off switch shuts off the power secondarily and an abnormal high temperature is generated. I never do that.

Since the liquefied petroleum gas vaporized in the vaporizer, the heat transfer area is further widened by the heat exchange pieces 12 formed to protrude in a plurality of pieces to the heating transmission part 13 toward the inner diameter of the gas vaporization moving part 30. Vaporization performance is higher.

The vaporized gas which is moved along the gas vaporization moving part 30 formed on the outer circumferential surface of the heating transmission part 13 is moved to the upper side flow passage 32 which penetrates to the outer circumferential surface side on the upper side of the liquid level adjusting part 2.

The vaporized gas introduced into the upper side of the liquid level adjusting unit 2 through the upper side flow path 32 is discharged to the discharge side gas stagnation unit 40 along the discharge port 24 formed on the upper side of the liquid level adjusting unit 2. Discharged.

The vaporized gas discharged to the discharge side gas stagnation part 40 is smoothly supplied to the user through the gas discharge valve part 34.

The liquid leakage preventing device vaporizer of the present invention has been described when operating normally.

When the liquefied petroleum gas supply valve part 6 formed in the vaporizer of the present invention is suddenly opened and an excessive amount of liquefied petroleum gas is introduced, or when the heater 18 temperature of the vaporizer does not rise properly, the internal water level of the vaporizer is increased. When raised, the liquefied petroleum gas flows into the liquid stagnation part 16 through the supply valve part 6.

At this time, the excess liquefied petroleum gas is rapidly moved to the upper liquid level control unit 2 through the inlet portion (26).

The liquefied petroleum gas rapidly moved to the liquid level adjusting unit 2 raises and lowers the lower surface of the buoyancy type liquid leakage preventing device 20 formed in the liquid level adjusting unit 2 due to excess and overpressure as shown in FIG. 4. .

The lower side surface of the buoyancy-type liquid leakage preventing device 20 is to form a hemispherical concave portion 42, it has a feature that can increase the reaction rate to the liquefied petroleum gas flows than the hemispherical convex formed .

The lower side liquid leakage prevention valve part 10 installed in the lower guide rod 60 formed to protrude in the center of the lower side of the buoyancy type liquid leakage preventing device 20 is also raised at the same time.

As described above, the lower side liquid leakage preventing valve portion 10 is raised to the lower side of the inlet portion 26 of the liquid level adjusting unit 2 and blocked as shown in FIG. 5.

As the amount of liquefied petroleum gas oversupplied to the liquid level adjusting unit 2, the trapezoidal inlet 26 is narrowed as the lower side liquid leakage preventing valve part 10 is raised. It is formed in the trapezoidal shape of the lower side liquid leakage prevention valve portion 10, and since the inlet portion 26 is also formed in a trapezoidal shape, the lower side liquid leakage prevention valve portion 10 is raised, the inlet portion 26 This is because it gradually narrows).

Therefore, the inlet portion 26 is gradually operated while the lower side liquid leakage prevention valve portion 10 of the buoyancy liquid leakage prevention device 20 is operated due to the excess amount of liquefied petroleum gas introduced into the inlet liquid retention portion 16. Since the amount of the liquefied petroleum gas introduced into the liquid level adjusting unit 2 introduced into the liquid level is automatically reduced, the liquefied petroleum gas is controlled without being discharged in the injected state.

When the amount of liquefied petroleum gas flowing into the inlet portion 26 of the liquid level adjusting unit 2 decreases, the pressure in the liquid level adjusting unit 2 is lowered, so that the buoyancy type liquid leakage preventing device 20 pushed to the upper side thereof has its own weight. Is lowered to its original position.

At the same time as the buoyancy-type liquid leakage prevention device 20 is lowered as described above, the lower side liquid leakage prevention valve part 10 formed integrally with the lower side is gradually lowered, thereby releasing the entrance 26 which is being blocked and widened. The liquefied petroleum gas which has been stagnated is smoothly supplied into the liquid level adjusting unit 2 again.

Therefore, the liquid leakage preventing device vaporizer of the present invention is automatically provided by the lower side liquid leakage preventing valve part 10 formed on the lower side of the buoyancy type liquid leakage preventing device 20 up to a predetermined amount and a predetermined level of the liquefied petroleum gas. Is adjusted.

In addition, as shown in Figure 5, the amount of liquefied petroleum gas of the inlet liquid stagnation part 16 and a certain level is increased to increase the amount of liquefied petroleum gas of the liquid level adjusting unit 2 through the inlet portion 26 to buoyancy type When the liquid leakage preventing device 20 is pushed to the upper side and the lower liquid leakage preventing valve part 10 blocks the inlet part 26, the liquefied petroleum gas is no longer introduced into the liquid level adjusting part 2.

At this time, even if the inlet part 26 is closed by the lower side liquid leakage prevention valve part 10, the buoyancy type liquid leakage prevention in the liquid level adjustment part 2 is prevented by the level of the liquefied petroleum gas which flowed into the liquid level adjustment part 2 at this time. The device 20 is raised to the upper side.

As described above, the buoyancy type liquid leakage preventing device 20 is continuously raised by the amount of liquefied petroleum gas in the state in which the inlet part 26 is blocked by the lower liquid leakage preventing valve part 10 as described above. Outflow prevention valve part 10 is a spring (8) is fixed to the fixing ring 14 to the lower guide rod (60), the spring (8) is pressed further lower liquid leakage prevention valve part 10 inlet It is sealed to the (26) side.

The buoyancy type liquid leakage preventing device 20 which is lifted by the elastic force of the spring 8 prevents the amount of liquefied petroleum gas or the overpressure from rising sharply to the liquid level adjusting unit 2 so that the vaporizer is momentarily operated. It is cut off slowly so as not to stop.

In addition, when the liquefied petroleum gas level of the liquid level adjusting unit 2 drops in the state in which the inlet part 26 is closed by the elastic force of the spring 8 fixed to the fixing ring 14 of the lower guide rod 60, the inlet part The lower side liquid leakage preventing valve part 10 which blocks the 26 is gradually lowered by the pressure of the spring 8 and the self-weight of the buoyancy type liquid leakage preventing device 20, so that it operates normally.

The lower end of the lower guide rod 60 is fixed to the lower side of the inlet side gas stagnation 16 to prevent the movement of moving up and down while moving up and down smoothly and left and right while moving up and down smoothly 59 Descend along).

In addition, the buoyancy-type liquid leakage prevention device 20 formed integrally on the upper side of the lower guide rod 60 of the fixed guide 59 fixed to the lower side guide rod 60 is lowered to the lower side Since it does not come in the inlet portion 26, the lower side liquid leakage prevention valve portion 10 is formed to be positioned so as to be supported without being lowered at any interval.

When the liquefied petroleum gas level is rapidly supplied to the inside, the vaporizer of the present invention is buoyant if the liquefied petroleum gas level in the liquid level adjusting unit 2 rises in a state where the inlet portion 26 of the liquid level adjusting unit 2 is blocked. The liquid outflow prevention device 20 is raised to the upper end of the liquid level control unit 2 so that the liquefied petroleum gas is not discharged to the discharge side gas stagnation part 40 so that the outlet port 24 is buoyant as shown by the dashed line in FIG. 5. It is secondarily blocked by the liquid leakage prevention device 20.

At this time, the upper side liquid leakage prevention valve (4) formed on the upper side of the buoyancy-type liquid leakage prevention device 20 is formed in a hemispherical convex shape so that the liquefied petroleum gas as the rounded surface is in contact with the discharge port (24) Since it is blocked, the liquefied petroleum gas is safely shut off to the discharge side gas stagnation part 40 in a liquid state.

The liquid leakage preventing device vaporizer of the present invention operated as described above is primarily blocked by the lower liquid leakage preventing valve part 10 of the lower side inlet part 26 of the liquid level adjusting part 2, and the liquid level adjusting part ( When the outlet 24 of 2) is secondarily blocked through the upper side liquid leakage preventing valve 4, the liquefied petroleum gas supplied to the inside of the liquid level adjusting unit 2 is stopped and does not flow in either direction.

In this way, when the amount of liquefied petroleum gas and the internal water level of the liquid level adjusting unit 2 are increased and the buoyant liquid spill prevention device 20 is operated to increase, the vaporizer stops operating. Due to this, in order to normally supply the safe gas evaporated to the user, the pressure of the liquefied petroleum gas which has been increased in the liquid level adjusting unit 2 should be released.

Therefore, in the present invention, as shown in Figure 6 is formed to discharge the gas in the liquid level adjusting unit 2 to release the pressure by the liquefied petroleum gas from the gas vaporization moving part 30 to the discharge side gas stagnation part 40 By releasing the bypass valve portion 22 blocking the hole 38, the vaporizer of the present invention is characterized in that it is simply restarted. That is, when the buoyancy liquid leakage preventing device 20 gradually descends while the water level in the liquid level adjusting unit 2 decreases, the upper outlet 24 of the liquid level adjusting unit 2 is opened, and the inlet portion 26 on the lower side is opened. The lower side liquid outflow prevention valve part (10) which closes) is also lowered and returned to the original state at the same time, so that the liquefied petroleum gas flows smoothly back into the liquid level control part (2) through the inlet part (26).

In addition, the liquid outflow prevention device vaporizer of the present invention can be coupled to the cover (9) formed on the outer side while sliding the heating transmission unit (13) in the longitudinal direction by an interference fit feature is easy to assemble.

In addition, as shown in FIG. 7, the heater 18, which is fitted into the heating transmission part 13 from the upper side to the lower side in the longitudinal direction, also loosens only the bolt fixed to the upper side, and can be easily removed by replacement. There is a characteristic.

8 is a view showing a modification of the liquid leakage preventing device vaporizer of the present invention.

The convex surface of the convex surface portion of the upper liquid flow prevention valve 4 formed integrally with the upper side of the buoyancy liquid flow prevention device 20 installed to be raised and lowered inside the liquid level adjusting unit 2 is shown in the drawing. A plurality of line grooves 61 are formed in the lower side to be dug along.

When the line groove portion 61 formed as described above is lifted by the liquefied petroleum gas in which the buoyancy type overpressure circuit breaker 20 is introduced, the upper side liquid leakage prevention valve 4 having the line groove portion formed at the upper side is raised to discharge port 24. Liquefied petroleum gas introduced into the inner side while contacting the) is not discharged to the outlet side gas stagnation part 40.

At this time, the liquefied petroleum gas introduced into the liquid level adjusting unit 2 is finely discharged side gas stagnation part 40 along the line groove 61 where the outlet 24 and the upper side liquid leakage prevention valve 4 is in contact with each other. Is discharged.

Therefore, the liquefied petroleum gas is not introduced into the lower inlet 26 of the liquid level adjusting unit 2 by the lower liquid outflow prevention valve unit 10, and the liquefied petroleum gas in the liquid level adjusting unit 2 flows in. Since the water level is gradually discharged along the line groove portion 61 of the upper side liquid leakage preventing valve 4, the level of the liquefied petroleum gas in the liquid level adjusting unit 2 is gradually lowered.

Since the gas is finely discharged along the line groove 61 as described above, when the level of the liquefied petroleum gas in the liquid level adjusting unit 2 gradually drops, the buoyancy type overpressure circuit breaker 20 is gradually lowered so that the liquid level adjusting unit 2 The lower side liquid leakage prevention valve part 10 which blocked the lower side inlet part 26 of () is also released, and liquefied petroleum gas is supplied to the inlet part 26 again, and is operated.

In addition, as another embodiment of the present invention will be described in detail as follows with reference to the accompanying drawings that only the liquid leakage prevention valve portion 10 is formed in the buoyancy type liquid leakage prevention apparatus 20.

9 is a view showing another embodiment of the liquid leakage preventing device vaporizer of the present invention.

In this embodiment, as shown in Fig. 9, a buoyancy type liquid leakage prevention device 20 which is raised and lowered by the level of the liquefied petroleum gas amount flowing into the liquid level adjusting unit 2 is formed.

The buoyancy-type liquid leakage prevention device 20 is formed with a liquid leakage prevention valve portion 10 formed integrally at the end of the flexible wire 60 so that the end portion thereof is extended to the lower side so as to block only the lower inlet portion 26. do. That is, the upper outlet port 24 described in the embodiment of the present invention is a structure that is discharged directly to the gas discharge valve 34 without a state, the lower inlet portion ( When only the liquefied petroleum gas is supplied, the buoyancy type liquid leakage preventing device 20 closes only the inlet part 26.

It is on the lower side of the buoyancy-type liquefied leakage prevention device 20, the liquid leakage prevention valve portion 10 is formed to be suspended by the flexible wire 60 to serve as the lower guide rod described in the present embodiment is liquefied petroleum gas When the liquefied outflow prevention device 20 rises to the upper side and rises at the same time as shown in the advantaged chain portion when over-supplied, the liquefied petroleum gas is blocked without being supplied anymore.

Therefore, the liquefied petroleum gas oversupplied through the inlet portion 26 of the liquid level adjusting unit 2 is no longer supplied, but transmits the temperature of the heater 18 formed on the outer circumferential surface of the liquid level adjusting unit 2 to supply the liquefied petroleum gas. It is vaporized by the heating transmission unit 13 formed to vaporize the supplied through the gas discharge valve 34.

When the liquefied petroleum gas oversupplied as described above is vaporized and supplied from the liquid level adjusting unit 2, the liquid level of the liquefied petroleum gas supplied to the liquid level adjusting unit 2 is reduced and the buoyancy type liquefied effluent prevention device 20 is self-weighted. And the liquid leakage prevention valve part 10 formed at the lower side of the buoyancy-type liquefied outflow prevention device 20 is also lowered at the same time, so that the inlet part 26 is opened again to liquefied petroleum to the liquid level control part 2. Gas is supplied smoothly.

In addition, when the liquefied petroleum gas supply valve part 6 is opened, the liquid leakage prevention valve part 10 so that the liquefied petroleum gas is momentarily not supplied through the inlet part 26 when the liquefied petroleum gas is excessively supplied to the liquid level adjusting part 2. ) Is formed into a hemispherical shape so that the hemispherical surface is brought into contact with each other, so that the sealing property is increased when the inlet portion 26 is closed.

Gas supplied from the large storage tank in which the liquefied petroleum gas is stored by the liquid outflow prevention device vaporizer of the present invention has an effect that can be smoothly supplied in a vaporized state without being in a liquid state when discharged.

In addition, it is possible not only to automatically adjust by the gas level without using an electronic device for controlling the vaporizer, but also to block the liquefied petroleum gas from being excessively supplied.

By the mechanical configuration of the liquid leakage preventing device vaporizer of the present invention can be produced in a small size has a very useful feature.

The present invention has many advantages in cost reduction because the carburetor can be reused by replacing only the heater without replacing the entire carburetor.
