Description

Vaccum antifreezing water supply device < RTI ID = 0.0 >

The present invention relates to an anti-freeze for preventing freezing, and more particularly, to an anti-freeze for preventing freezing, and more particularly, to a vacuum incinerator which surrounds a water pipe and a part of a water receiver to prevent freezing of water remaining in the space, In addition, it is also possible to provide the shielding pipe in a state of being subjected to the vacuum process in order to induce the integration of the subject water pipe by the fitting type coupling or to perform a separate vacuum operation after installation in the water supply facility And more particularly, to a vacuum flotation prevention device for freeze prevention which can be used more universally by realizing improvement of the related structure so as to completely remove the air in the internal space.

Normally, an uncooled plug is applied to a series of water supply facilities for allowing water supplied from the water source through the ground to be supplied by a predetermined water pipe (water pipe) or water pipe, It is used as a means of protecting the water pipes and the like from being frozen or freezing in low places.

Generally, a water pipe is buried in the ground so that it is not frozen even in the winter when the temperature falls below the freezing point. However, in order to use the water pipe, the water pipe is connected from the ground to the ground. In case of indoor use, there is no problem. However, when the outdoor location of the water pipe is exposed to the outside air, if the temperature falls below the freezing point in the winter season, the water remaining in the water pipe may be frozen and the water can not be used. In order to prevent such problems, freezing is prevented by installing a coin in a vertically installed portion connected to the ground and connected to a ground water pipe.

For example, Korean Utility Model Registration No. 242191 entitled " Pre-flood residual water discharge device "(hereinafter referred to as " pre-registration design ") is disclosed.

However, such a line registration design has caused a serious problem by making the water pipe and the coin to be heated by the elbow. This is because the structure of the drain valve is complicated due to the nature of the float, and is composed of parts damaged and worn in a short time, This is a problem that requires frequent maintenance due to the fact that the life span is not long.

In other words, the coin is completely fixed so that it can not be disassembled when the dispenser valve is initially assembled in consideration of the airtight condition. When the dispenser valve fails, the coin should be separated from the elbow and replaced with a new one. The excavation work required to secure the work space enough for the worker has resulted in waste of manpower and economic loss. Especially when the surface of the ground is treated with concrete or tile, This is due to the fact that there is a serious problem in replacing and repairing such as when the ground is frozen and the digging work is difficult.

Conventionally, there is a method of using an exposed water pipe surrounded by a heat insulating material and sealing it with a case, a method of discharging a certain amount of tap water at a predetermined time interval, a method of discharging a certain amount of tap water at a predetermined time interval, A method of installing and discharging it was used.

However, in the case of using the case surrounded by a heat insulating material and sealing the outside with a case, when the temperature is low, the heat insulating effect of the heat insulating material, that is, the heat transfer of the heat insulating material itself and the convective heat transfer of the inside air, There is a problem that the tap water is frozen and the method of discharging the tap water at regular intervals causes a loss of unnecessary tap water and requires a complicated and complicated control device.

In addition, since the method of discharging the water to the water pipe by installing a separate outlet is difficult due to the complicated structure, it is not only costly to manufacture, but also troubles frequently occur due to the complicated structure, There is another problem such that the outlet is clogged. Therefore, there is a need for an improvement measure for this problem.

The present invention has been made in order to more positively solve the above-mentioned problems, and it is an object of the present invention to provide a vacuum flushing tube that surrounds a water pipe and a part of a water receiving part to prevent a freezing of water remaining in the space, To provide a solution to the problem.

In supplying the shut-off pipe, it is provided in the state of being subjected to the front vacuum processing, thereby inducing the integration of the subject water pipe by the fitting type coupling or installing the water pipe in the water supply facility and performing a separate vacuum operation to completely remove the air in the internal space It is another challenge to provide the relevant structure so that

Another object of the present invention is to improve the related structure of the valve part for manipulating whether or not the water pipe is blocked, thereby maximizing the efficiency of the related function.

According to an aspect of the present invention, there is provided a vacuum coin 100 for freeze prevention,

The vacuum coin 100 includes a main water pipe buried in the ground to supply water, a water pipe 10 connected to the main water pipe and exposed to the ground, and a water pipe 10 screwed to one side of the water pipe, And a valve unit (30) which is vertically operated so as to determine whether or not water is supplied in the water pipe, so as to prevent the water remaining inside the water pipe from being frozen before the water pipe 10, the shielding pipe 40 having an extension length extending from the ground to the ground and keeping the internal space in a vacuum state is disposed in an overlaid manner, and the shielding pipe 40 is disposed over the water receiving portion 20, (41) covering the entire area from the outside where the mutual coupling of the base (10) is carried out; A body portion 42 which extends downward vertically downward than the width of the head portion and which covers a front surface of the water pipe corresponding to the longitudinal direction of the water pipe from the outside to the upper portion and the lower portion, 30 and the hollow pipe through which the water pipe 10 is inserted, the water pipe is received through the hollow portion of the shut-off pipe, so that the upper end and the lower end region of the shut-off pipe are sealed and fixed to the outer surface of the valve portion and the water pipe, respectively And the cutoff pipe 40 is provided with a cap 41 for venting the internal space by a vacuum device so as to be able to be carried out through a separate vacuum process after being installed in the water supply equipment, And a vacuum gauge 44 connected to the body portion 42 so that the degree of vacuum of the internal space can be visually recognized, The inner space of the water pipe 10 is provided with a rounded step 11 protruding in the same line as the horizontal line position of the power receiver 20 with respect to the central direction from the inner surface thereof, (32) for changing the vertical position while determining the degree of screw connection by an operation between the operation and the operation, and a step (11) at the bottom of the winding part, A supporting body 33 integrally formed on the end portion of the supporting body and extending and descending integrally down to the peripheral region of the stepped portion and being vertically received by the vertical movement of the winding portion, A sealing member 34 of a synthetic resin material which is closely contacted on the same line on the bottom surface of the step 11 so as to block the perforated space or to open the perforated space while extending downward relative to the vertical linear position of the step, It provides a vacuum freeze protection unit characterized in that the coin properties.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to accomplish them, will become apparent by reference to the embodiments described in detail below with reference to the accompanying drawings. However, it is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It is intended that the disclosure of the present invention be limited only by the terms of the appended claims. And, throughout the specification, like reference numerals refer to like elements.

It is noted that the present invention relates to a vacuum coin 100 of the type disclosed in the preamble to prevent freezing and provided in a vacuum for this purpose.

In detail, since the shielding pipe 40 in a vacuum state enclosing the water pipe 10 and a part of the water receiver 20 actively prevents freezing of water remaining in the space, water leakage due to freezing or frost In addition, it is also possible to provide the shielding pipe 40 in a state of being completely vacuum-treated in the supply of the shielding pipe 40 to induce the integration of the subject water pipe 10 by the fitting type coupling, And the improvement of the related structure so that the air in the internal space can be completely removed through the vacuum operation, thereby making it possible to use the general purpose more.

FIG. 1 is a perspective view showing a vacuum floating state for freeze prevention according to a preferred embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a main part of the present invention in detail before freezing for freezing.

As shown in FIGS. 1 and 2, the vacuum coin 100 according to the present invention is constructed such that a shielding pipe 40 is disposed in close contact with the outside of the water pipe 10 to evacuate the inner space of the shielding pipe, So that the water inside the water pipe can be frozen or the water pipe can be prevented from being damaged.

Heat transfer occurs in three forms: conduction, convection, and radiation. However, in the vacuum state, there is no medium to transfer heat, so heat is transferred only in the form of radiation, and conduction or convection heat transfer does not occur.

Also, even if not completely vacuumed, conduction heat transfer and convection heat transfer are drastically reduced at a lean air density, and heat loss is reduced, so that the water pipe is not frozen or frozen.

That is, the vacuum coin 100 includes a main water pipe embedded in the ground to supply water, a water pipe 10 connected to the main water pipe and exposed to the ground, And a valve unit 30 which is vertically operated to determine whether or not water is supplied in the water pipe, so as to prevent freezing of water remaining in the water pipe.

2, a shielding pipe 40 having an extension extending from the ground to the ground and keeping the internal space in a vacuum state is superimposed on the outer circumference of the water pipe 10, (40) has a head (41) covering the entire area from the outside to the area where mutual coupling of the water receiver (20) and the water pipe (10) is performed; A body portion 42 which extends downward vertically downward than the width of the head portion and which covers a front surface of the water pipe corresponding to the longitudinal direction of the water pipe from the outside to the upper portion and the lower portion, 30) and a hollow portion (no identification number) into which the water pipe 10 is inserted, the water pipe is accommodated through the hollow portion of the shutoff pipe, and the upper end portion and the lower end portion of the shutoff pipe are connected to the outer surface of the valve portion and the water pipe As shown in Fig.

As shown in FIG. 2, the shutoff pipe 40 is provided in a state of being subjected to a front vacuum process so as to induce the integrated water pipe 10 to be integrated with the water pipe 10, or installed in a water supply facility, It is desirable to provide an associated structure so that the air in the interior space can be completely removed.

In particular, the shut-off pipe 40 is formed in the upper part of the head 41 so as to interpose the needle pin of the vacuum apparatus so that the vacuuming of the internal space by the vacuum apparatus can be performed through a separate vacuum operation after being installed in the water- And a vacuum gauge 44 connected to the body portion 42 so that the degree of vacuum of the internal space can be visually recognized.

Although not shown in the drawing, the vacuum device is a means for sucking the air inside the shielding tube to achieve a complete vacuum state, and normally, a connecting means such as a needle pin is used to form a forced- To achieve the desired purpose.

In the inner space of the water pipe (10), a step (11) protruding from the inner surface toward the center is formed in a round shape.

The step 11 is a component that contributes to the function of blocking or circulating the water by interaction with the valve unit 30 to be described later. Preferably, the step unit 11 should be provided on the same line as the horizontal line position of the power receiver 20 do.

In addition, the valve unit 30 includes an operation unit 31 having a rotation range in both directions by a user's selection; a rewinding unit 32 for varying the up-and-down position while determining the degree of screw- A supporting body 33 extending integrally downward to reach the peripheral region of the step 11 from the bottom surface of the winding portion and being vertically moved by vertical movement of the winding portion; And a sealing member (34) for closing the perforated space or extending downward relative to the vertical line position of the step to open the perforated space.

The sealing member 34 is made of a soft synthetic resin or other rubber material, and is a component for completely blocking or communicating the open space of the step 11 due to rotation between operations. However, in the present invention, it is possible to induce a more complete sealing force than to raise and lower the sealing member 34 at the bottom of the step 11.

In the present invention, freezing at a specific temperature was tested to determine whether the function as an immobile coin could be maintained even at an extreme temperature. The results are shown in Tables 1 and 2 below, and therefore objectivity is recognized.

The test results in Table 1 show that there is no abnormality after testing the cold resistance before vacuum flooding at -30 ° C. The test equipment was a thermo-hygrostat for 24 hours. As a result, it was judged whether or not the internal solution was frozen and whether or not there was an external appearance abnormality.

The test results in Table 2 show that there was no abnormality after freezing before freezing at 50 ° C, and the test time was 8 hours. As a result, the internal solution was not frozen.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be clarified. Therefore, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
