Description

In / outlet valve for portable boiler

The present invention relates to an inlet / outlet valve of a portable boiler, and more particularly, in a portable boiler for quickly heating a limited space in the outdoors or indoors using a small heat source such as a mobile burner,

The present invention relates to an improvement of an in / outlet valve mounted on a flow path of hot water and steam generated in the portable boiler.

In general, a boiler is a tool derived from heating water at room temperature to obtain hot water or steam, and is classified into an industrial boiler and a domestic boiler.

The industrial boiler is characterized in that it is used in places where a large amount of hot water is required at a time such as steam generation and bathrooms required in industrial sites, etc.

Domestic boilers are used for indoor heating and hot water in winter.

Industrial and domestic boilers as described above induce the state change of water by using the heat of combustion of raw materials such as oil or gas, and are configured to have different calorific values and efficiency depending on the purpose of use.

As such, the boiler for heating the water at room temperature by the heat of combustion of the fuel to generate steam and hot water;

In addition to the industrial and domestic boilers described above, a portable (outdoor) boiler is applied for heating the local space in outdoor activities or indoors.

Such portable boilers can be easily and quickly heated by using a Coppel or a portable burner during the spring, autumn and winter seasons except summer.

As shown in FIG. 1, the inlet valve 10, which is a substantially cylindrical shape, performs a heat conduction by direct contact with a heat source, and an inlet valve 10 which allows a flow of water only in one direction to the upper portion thereof. The replenishment water tank 2 is interposed between the phases, the outlet valve 11 for steam supply is formed on one side of the heating water tank (1).

As shown in FIG. 2, the inlet valve 10 and the outlet valve 11 form a plurality of stages 13 having a cylindrical body 12 having a roughly shaped shape to form a male screw 14 provided at an outer circumference thereof. Through the heating water tank (1) and the supplemental water tank (2),

The center of the main body 12 is provided with a through hole 16 in which steel balls 15 and 15 'are operated by pressure deviation between the heating water tank 1 and the replenishment water tank 2.

The replenishment water tank (2) is provided with a discharge pipe is fastened to the hot water pipe embedded in the mattress, the outlet valve 11 formed in the heating water tank (1) is fastened with the inlet pipe of the mattress.

The portable boiler configured as described above is filled with a predetermined amount of water in the heating water tank (1) and heats the heating water tank (1) with a heat source of a coppel or a portable burner to generate hot water and steam.

The generated steam forms the inside of the heating water tank 1 at a high pressure to closely contact the steel ball 15 in the inlet valve 10 to the top to prevent the water stored in the supplement water from flowing into the heating water tank 1 and At the same time,

The steel ball 15 'in the outlet valve 11 formed on one side of the heating water tank 1 is moved to the side (right side in the drawing) so that the generated steam can circulate in the mattress through the inlet pipe.

If the pressure in the heating tank is exhausted due to the continuous heating as described above,

The steel ball 15 in the inlet valve 10 drops due to its own weight to open the closed through hole 16, and then the water in the make-up water tank 2 flows into the heating water tank 1 and returns to steam. Change.

As described above, when the steam in the heating water tank 1 is equal to or higher than a predetermined pressure, the steam structure of the above-described contents is repeated.

As described above, the portable boiler includes a steel ball 15 inserted into the inlet valve 10 interposed between the heating water tank 1 and the supplemental water tank 2 and the outlet valve 11 provided on one side of the heating water tank 1. (15 ') caused the steam to circulate due to the action, and had some problems as follows.

First, the steel balls 15 and 15 'in the inlet valve 10 and the outlet valve 11 maintain continuous contact with high temperature steam, which means that the fluorine lamp contained in the water has a high temperature (about 100 ° C.). Changes to scale occur on the surface of the steel balls 15 and 15 '.

The above-mentioned scale conception inhibits the smooth opening and closing of the inlet valve 10 and the outlet valve 11, resulting in excessive discharge of the steam and circulation, resulting in excessive pressure rise of the heating water tank 1.

In addition, the inlet valve 10 that connects the heating water tank 1 and the supplemental water tank 2 flows back to the supplemental water tank 2 immediately due to an inverted vapor shape, and the supplemental water boils and overflows to the user. He had serious problems such as causing physical damage.

In this regard, the present invention was devised to solve the above-mentioned problems, and the shape of the inlet valve connecting the heating water tank and the replenishment water tank was formed in a curved portion rather than in a straight shape to be durable at high temperatures (180 ° C). Via packing of silicon material having

The inside of the outlet valve required for the discharge of steam is to improve the circulation efficiency of hot water and steam through the thin packing to increase the thermal efficiency and safety.

The in / outlet valves 30 and 40 of the portable boiler of the present invention are provided between the heating water tank 3 and the supplemental water tank 4 and the upper one side of the heating water tank 3 as shown in FIG. 3.

As shown in FIG. 4, the inlet valve 30 is a block-type housing 31 having a fastening port 32 formed in the heating water tank 3 and the supplemental water tank 4 on the same upper and lower axes. A male screw p1 necessary for fastening is provided, and an insertion hole 33 for inserting the nozzle 36 necessary for fixing the packing 50 is provided downward at one side by giving a specific angle θ.

The bottom surface of the nozzle insertion hole 33 is to pass through the water channel (34) formed in the interior of the housing 31, the water channel 34 is formed by forming a bent portion of a predetermined angle at the intermediate point (p) Organize to ｈ 'type.

The bent portion of the channel 34 has a constant height h at a point coinciding with the bottom surface of the nozzle insertion hole 33 for the seating of the packing 50 for controlling the flow of water in the replenishment water tank 4. 34) is provided with a projection 35 concentric circles.

The packing 50 interposed on the bottom surface of the nozzle insertion hole 33 is made of silicon or viton (fluorine rubber) material without shape change and performance deterioration even at a high temperature (180 ° C).

As shown in FIG. 6, the protrusions 51 and the depressions 52 form a rough shape and are seated on the protrusions 35 formed at the tip of the water channel 34 to protrude from the inner wall of the nozzle insertion hole 33. 51 maintains contact with each other, and the depression 52 serves as a transport path for water when the water channel 34 is opened.

The contact state between the packing 50 and the inner wall of the nozzle insertion hole 33 maintains a fitting tolerance such that the flow of the packing 50 is smooth due to the pressure difference.

As described above, water introduced through the inlet valve 30 linking the supplemental water tank 4 and the heating water tank 3 is changed into a state of steam in the heating water tank 3 and discharged through the outlet valve 40. Circulating in the mattress,

The outlet valve 40 extends to the bottom surface 42 of the heating water tank 3 by using a fastening port 41 formed on one side of the heating water tank 3 to provide hot water and steam. A valve housing 44 having a pipe 43 for simultaneously discharging,

The nozzle 45 is fastened to the tip of the valve housing 44 to accumulate and discharge the steam discharged smoothly.

Inside the valve housing 44 is provided with a projection 46 for seating the same packing 50 as the inlet valve 30,

The nozzle 45 has a substantially cylindrical shape as shown in FIG. 5, and forms a hexagonal stepped portion 47 at the center to improve a fastening force with the housing 44.

A male screw 48 is formed at one end to be coupled to the female screw 49 formed in the valve housing 44.

Below the male screw 48 (left in the drawing), a plurality of through-holes 60 for the transport space of the steam are formed to form a constant inclination angle θ 'so that the extension lines can be mutually intersected at one point.

The nozzles 45 interposed between the inlet valve 30 and the outlet valve 40 are equipped with a sealing material 61 such as an O-ring between phases for airtightness with the housings 31 and 44, respectively.

Referring to the operational state of the present invention configured as described above compared with the problems of the conventional configuration is as follows.

First, the nozzle 36 formed in the inlet valve 30 is opened to allow the water filled in the replenishment water tank 4 to flow into the heating water tank 3.

The heating water tank 3 is heated through a heat source such as a copel or a mobile burner to heat the filled water to have an appropriate temperature.

The heated water is circulated through the hot water pipe embedded in the mattress through the pipe 43 of the outlet valve 40 provided to the bottom surface of the heating water tank 3, and heated to an appropriate temperature, and then the supplementary water tank 4 Flows into).

As described above, the water in the heating bath 3 is discharged through the outlet valve 40 at a point below the break point (about 80 ° C.) to perform a primary heating operation,

This has the advantage that the portable boiler of the conventional configuration significantly reduces the heating time compared to the heating action through the steam.

As described above, a small amount of water remaining in the heating water tank 3 after the discharge of the hot water is completed generates steam due to continuous heating.

The generated steam is simultaneously introduced into the channel 34 formed in the inlet valve 30 and the outlet valve 40 while raising the pressure in the heating water tank 3.

The steam introduced into the inlet valve 30 is closed by the packing 35 mounted on the bent portion p of the waterway 34 with the protrusion 35 by using the transfer pressure to close the waterway 34. It will not be possible to proceed,

The steam introduced into the outlet valve 40 is discharged to the outside in the integrated state through the through hole 60 formed in the nozzle 45 while pushing the packing 50 upward.

As the steam 34 is closed by the packing 50 of the inlet valve 30, the inflow into the supplemental water tank 4 is impossible, and the steam is discharged to the outside through the outlet valve 40 only.

If the remaining hot water is exhausted as described above and no further steam is generated, the pressure in the heating water tank 3 is lowered.

As a result, the hot water in the replenishment water tank 4 falls into the heating water tank 3 while pushing upward the packing 50 which closed the waterway 34 using the pressure deviation.

At this time, by using the nozzle 36 provided on one side of the inlet valve 30, it is possible to control the amount of water falling by adjusting the opening amount of the packing (50).

As described above, the hot water introduced into the pressure drop in the heating water tank 3 again contacts the inner wall of the heated water tank 3 to form a state change with steam in a short time.

The generated steam again increases the pressure in the heating water tank 3 to close the waterway 34 with the packing 50 of the inlet valve 30 to prevent the inflow of hot water and the reverse flow of steam at the same time.

As described above, the packing 50 mounted in the in / outlet valves 30 and 40 controls the flow of hot water and steam,

It is possible to open and close the channel 34 smoothly even with a small pressure deviation by minimizing the surface tension due to the projection 35 formed at the tip of the channel despite the thin disk shape.

In addition, since the material and shape of the packing 50 is made of a synthetic resin such as silicon and urethane, scale frosting does not occur even under continuous contact with high temperature steam, thereby providing excellent airtightness when the water channel is closed.

The idea that the scale is not caused is that the steel ball that controls the opening and closing of the conventional waterway can achieve excellent performance as compared to the smooth operation is not possible by the scale.

In addition, since the shape of the packing 50 forms a rough shape, it is easy to discharge hot water and steam, resulting in an increase in heating efficiency.

As described above, the in / outlet valve of the portable boiler according to the present invention increases the control reliability of the hot water and steam and induces a smooth circulation, thereby preventing the boiling water of the replenishment water tank due to the backflow of steam, thereby enabling stable operation. ,

It is a useful design that can prevent deterioration of durability by preventing scale implantation on the packing surface that controls the opening and closing of waterways.
