Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve chamber having a condensation prevention function,

The present invention relates to a valve chamber having a dew condensation preventing function, and more particularly to a dew condensation preventing paint having an anti-condensation and dew condensation preventing function on the entire inner and outer surfaces of a valve chamber, Thereby preventing condensation from occurring inside the valve chamber.

The conventional valve room having a dew condensation preventing function is disclosed in Japanese Patent Laid-Open No. 10-1683427 (the title of the invention: a valve chamber having an anti-flooding function and a dew condensation preventing function).

In the above-described prior art, an inlet and an outlet pipe in which an underground buried pipe is connected to both sides of a lower portion of a valve chamber body provided with a manhole at an upper portion thereof are provided, and between the both side entrance and exit pipes inside the valve chamber body, a flow of fluid flowing inside the buried pipe is opened Wherein the outer surface of the valve chamber body is formed of a corrugated steel tube having a plurality of protruded convex portions spaced a predetermined distance apart from each other and is provided in a passage portion to which the manhole and the valve chamber body are connected, And a heat insulating cover which is made of a urethane foam foamed material and is opened and closed.

Such a conventional invention has the same object as the present invention in that dew condensation does not occur in the inside of the valve chamber main body, but the specific structure for realizing the object is different from that of the present invention.

In the prior art, there is a problem that the manufacturing cost is increased because two steel tubes are used, and a urethane foam foamed material (insulator) is filled between the corrugated steel pipe and the inner steel pipe. There is a problem that a heat insulating material having a low thermal conductivity between the corrugated steel pipe and the inner steel pipe Even if it is charged, the thickness of the insulation should be filled with the heat because the heat conduction is made through the insulation.

As a reference, an excerpt from the Internet blog (http://blog.naver.com/container_j) shows that "It is applied to the central region according to the rate of heat transfer from July 1, 2016, and the thermal conductivity is 0.020 W / ((1 / 0.180) * 0.020 = 0.11111111 when the urethane foam with urethane foam is applied. In other words, the urethane foam must be foamed to a thickness of 112 mm or more so that there is no problem in completing the building. "

As shown in the above reference, when the urethane foam is to be applied to the building by thermal insulation, it is necessary to foam the urethane foam to a thickness of 112 mm or more to obtain a thermal insulation effect. Therefore, when the urethane foam is applied to the conventional invention It is necessary to construct the wall to a thickness of 110 mm.

If the urethane foam is to be applied in a thickness as much as 110 mm, there is a problem that the manufacturing cost is increased because the outside of the corrugated steel pipe constituting the valve chamber must be increased correspondingly. In this case, Therefore, there is a problem that the dew condensation preventing effect is lowered.

The valve chamber 1 according to the embodiment of the present invention shown in FIG. 8 is entirely similar to that of the first embodiment, but one embodiment may be modified in consideration of the fact that the inner plate 16 is formed of an FRP plate or a synthetic resin plate The inner plate 16a is made of a thin steel plate, and on the outer side thereof, an iron plate (a valve chamber main steel plate 11) constituting the valve chamber main body 2 ).

Therefore, the inner plate 16a made of a thin steel plate to be used in the present embodiment is formed of an inner plate 16a made of a thin steel plate when air is drawn out from the vacuum layer 7 rather than an FRP plate or a synthetic resin plate, So that the supports 13a can be spaced apart at wide intervals.

6 and 7 in the case of the large valve chamber 1 and the configuration in which the inner door 21 is hingedly installed using the turbine buckle 29 in the manhole 3. In the case of the large valve chamber 1, ) Are the same as those of the first embodiment, so that the description of the same configuration will be omitted.

The integral construction of the valve room main body 2 is such that the antifouling paint having heat insulating and dew condensation preventing functions is applied to the entire inner and outer surfaces of the valve chamber main body steel plate 11 to form the heat insulating paint layer 6, And a thin metal plate (not shown) is formed on the inner surface of the valve chamber main body steel plate 11 of the valve chamber body 2 except for the open portion of the valve chamber body 2 below the manhole 3 and the portion of the valve chamber body 2, An inner plate 16a made of a valve body main body steel plate 11 is provided at an interval from the inner surface of the valve body main body steel plate 11 to form a vacuum layer 7 between the inner plate 16a and the inner surface of the valve body main body steel plate 11 .

A plurality of support rods 13a for preventing the inner plate 16a from being bent inward are formed between the inner plate 16a and the inner surfaces of the valve chamber main steel plate 11 in a process of forming the vacuum layer 7, And air is drawn between the inner plate 16a and the inner surface of the valve chamber main body steel plate 11 at a predetermined position on one side of the inner plate 16a to separate the inner plate 16a and the valve chamber main body steel plate 11, A check valve 20 is provided to form a vacuum layer 7 between the inner surfaces of the check valve 20.

The inner plate 16a and the support table 13a are coupled by a bolt 14a and a silver foil 15 containing aluminum foil or silver nitrate is coated on the inner surface of the inner plate 16a .

The inner surface of the inner plates 16, 16a from above is to refer to the inner surface that a person can see and touch with when the person enters the inner space of the valve body 2.

The operation of the present invention will be described with reference to FIGS. 1 to 8. FIG.

First, in the case where the valve chamber 1 according to the present invention is to be buried in the ground, after the operator enters the internal space of the valve chamber 1, the check valve installed in the inner plates 16, When the vacuum pump is operated in a state where the suction pipe end of the vacuum pump (not shown) is connected to the vacuum chamber 20, the air in the vacuum chamber 7 of the valve chamber body 2 is drawn out by the action of the vacuum pump, The inner space of the vacuum chamber 7 becomes a vacuum state.

1 to 4, several support rods 13 are provided in a lattice form between the valve plate main body steel plate 11 and the inner plate 16, and the support rods 13 Several inner plates 16 are provided on the inner space side of the inner valve chamber main body 2. These adjacent inner plates 16 are sealed by a sealing material 17 such as silicon, A number of ventilation grooves (12) are formed in the support base (13).

Therefore, the several supporting rods 13 form several independent spaces in the form of a lattice, but the respective independent spaces, that is, the state in which the vacuum layers 7 communicate with each other by the ventilation grooves 12 formed in the respective supporting rods 13 The air in the spaces communicating with each other when the air is drawn from one side of the check valve 20 side through the space of the other side by the ventilation groove 12 So that the vacuum layer 7 is evacuated.

When the air inside the vacuum layer 7 is drawn out by using the vacuum pump as described above, each of the inner plates 16 tends to be bent toward the valve chamber main steel plate 11 by the vacuum pressure, 16 are supported by the support member 13 installed in a lattice form, the internal plate 16 is minimally bent toward the valve chamber main body steel plate 11. [

The air in the space between the valve chamber main body steel plate 11 and the inner plate 16, that is, the space inside the vacuum chamber 7 is taken out, and the set vacuum pressure displayed on the pressure gauge (not shown) When the set pressure is reached, the operation of the vacuum pump is stopped and the connecting hose is separated. The vacuum state is maintained while maintaining the set vacuum pressure in the vacuum layer 7 by the check valve 20.

In the embodiment shown in Figs. 1 to 4, since the inner plate 16 is formed of a synthetic resin plate including FRP, since the present invention constitutes much more bending than the steel plate, the support stand 13 is installed in a lattice form The area for supporting the inner plate 16 is increased and the bending of the inner plate 16 toward the valve chamber main body steel plate 11 is minimized.

The bolts 14 welded to the end portions of the valve plate main body steel plate 11 pass through the respective support rods 13 so as to be inserted through the sealing washer 18 and are nuts, So that it can be supported more stably.

8, the inner plate 16a is made of an iron plate and less likely to be bent than a synthetic resin plate. However, even in the case of the inner plate 16a made of an iron plate, An inner plate 16a made of an iron plate can be inserted into the valve chamber main body steel plate 11 side by means of the valve plate 13 so that several support rods 13a are installed between the valve plate main body steel plate 11 and the inner plate 16a So that deflection of the inner plate 16a made of a steel plate can be minimized.

After the vacuum state of the vacuum chamber 7 of the valve chamber 1 is maintained, the valve chamber 1 is buried at a predetermined depth in the ground and the inside of the manhole 3 The hook 28 provided at the lower end of the turn buckle 29 is hooked to the hook portion 24 provided on the upper surface of the inner door 21 and the turn buckle handle 27 ) In the locking direction.

As is well known, the turn buckle 29 is fastened to the turn buckle handle 27 in a direction opposite to the left turn and right turn so that the distance between the two side thread portions is increased or decreased according to the turning direction of the turn buckle handle 27, The distance between the hinge bracket 26 and the hook portion 24 of the inner door 21 is narrowed when the turn buckle handle 27 is turned to the shorter side so that the inner door 21 The opening of the manhole 3 is closed.

At this time, a stretch packing 23 for stretching the lower portion of the manhole 3 is provided at the upper portion of the inner door 21 to seal the opened lower portion of the manhole 3, The manhole cover 3a is closed and the manhole 3 side is doubly locked so that the outside air does not flow into the internal space of the valve chamber main body 2. On the upper surface of the door main body 22 of the inner door 21, So that it is possible to effectively prevent the outside air from being introduced into the internal space of the valve chamber main body 2.

In the valve chamber 1 buried in the ground in such a state, condensation does not occur in all of the valves 1 and 2 because the manhole 3 is provided with an upper manhole cover 3a and an inner door 21 is installed in the inner door 21 and the heat insulating material 9 is installed on the inner door 21 to completely block the outside air from entering the inside of the valve chamber body 2 through the manhole 3, 2 is provided with a layer of vacuum layer 7 on the same principle as a thermos bottle so that no heat is transferred between the inside and the outside of the valve chamber main body 2 so that condensation does not occur inside the valve chamber main body 2.

That is, on the inner and outer surfaces of the valve chamber main body 2, the anti-condensation paint having the function of preventing adiabatic and dew condensation is applied to form the heat insulating paint layer 6 so as to prevent heat insulation and condensation in the valve room main body steel plate 11 do.

The above-mentioned anti-condensation paint is being installed in the make-up house of Korea Co., Ltd., and it is said that "the construction of the best condensation preventive paint hit ball" now on the internet blog (http://blog.naver.com/thfthfdl77/220791302757) Quoting some of the content introduced as.

"The anti-condensation paint" HEAT-BALL ™ "has an empty hollow table-shaped vacuum ceramic, and the hollow vacuum ceramic has excellent performance in forming an insulating layer that lowers the thermal conductivity. Vacuum ceramics added to the heat ball are applied to the wall of the veranda and form an insulation layer on the cement wall. Indoor air warmed by heating is unable to transfer heat to the outside by the insulation layer and circulates inside. That's why Heat-Ball ™ is a way to lower the thermal conductivity to prevent condensation on the wall, preventing condensation. "

As described above, in the heat insulating paint layer 6 coated with the anti-condensation paint, the steam is prevented from being condensed on the wall surface by the method of lowering the thermal conductivity, thereby preventing condensation. In the vacuum layer 7 inside, The temperature difference between the inside and the outside of the valve chamber 1 does not occur, so that condensation does not occur in the valve chamber 1.

The inner surface of the inner plates 16 and 16a is coated with silver nitrate or attached with a foil 15 containing aluminum foil. This prevents the silver nitrate or silver foil 15 from moving due to conduction or reflection It is possible to prevent more perfect heat insulation and consequent condensation phenomenon.

I cite some of the contents of the internet blog (freebmuonline.tistory.com/572) about the principle of thermos.

"The principle of a thermos bottle is a bottle made by vacuuming the air in the middle of the double wall of the glass and plating the inner wall of the double wall. Removing air is to prevent heat conduction by air, and plating is to prevent heat conduction by radiation. That is, when the temperature of the outer environment is high, the radiation from the outer environment is reflected to reduce the absorption of the heat, and when the temperature of the outer environment is low, the radiation from the contents is reflected and returned to the inside to prevent radiation to the outside . Since the entry and exit of heat with the outside world is blocked in this manner, the thermos bottle is used for the purpose of keeping warm or keeping the refrigerator. &Quot;

That is, the valve chamber 1 according to the present invention prevents heat insulation and condensation in the primary heat insulating coating layer 6 coated with the anti-condensation paint and forms a vacuum layer 7 such as a secondary thermosensitive bottle and an inner plate 16 And 16a, the heat insulation of the valve chamber 1 can be made perfect, and an excellent heat insulating effect and an excellent dew condensation preventing effect can be expected.
