Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a water piping system having a foreign matter removing function inside a pressure tank,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water piping system having a function of removing a foreign substance in a pressure tank, and more particularly, to a water piping system having a function of discharging a foreign substance, which is deposited or stagnant, And more particularly,

Generally, in a water piping system, a transient condition occurs in which a flow rate and a flow velocity rapidly change in the case of a pump stoppage or a valve closing. This phenomenon is referred to as a water hammer. As a result of this water shock phenomenon, the pressure in the pipe suddenly increases or the pressure in the pipe falls below the saturated vapor pressure of the water to generate steam, and then, in the process of the column separation & return, It can cause damage.

1, a normal water piping system includes a pump 2 for pressurizing the water introduced from the suction side 1, a main pipe 10 to which pressurized water is fed, And discharging side (3). The main pipe 10 is provided with a check valve 4 for preventing fluid flow interruption and reverse flow, a flexible joint (not shown) for preventing vibration and a shutoff valve (not shown) for interrupting the water flowing into the discharge side 3, And so on. In this water piping system, when the pump 2 is suddenly stopped, the fluid conveyed through the main pipe 10 temporarily flows in the main flow direction of the main pipe 10 due to inertia, and the discharge amount from the pump 2 A negative pressure is generated on the rear end side (outflow side) of the pump 2 as the pump 2 is rapidly reduced, so that an intra-pipe cavity is generated and the fluid flows backward to fill the cavity. At this time, the water pressure shock due to the high pressure of the fluid flowing backward can cause the main pipe 10 and the pump 2 to be damaged.

On the other hand, the water impact may be caused by the slam phenomenon due to the disengagement of the check valve 4. [ As shown in FIG. 1, the slam phenomenon occurs when the disc 4a constituting the check valve 4 is opened in the fluid transfer direction like 'A' between the drive of the pump 2, To the 'B' position by the fluid to which the disk 4a is attached, and receives a high pressure of the fluid to form a shock wave. In other words, the disk 4a is 'banged' and closes. Such a shock wave due to the slam phenomenon may be transmitted to the main pipe 10 and the pump 2 and may result in breakage of the water piping system.

In order to alleviate such a water impact, a pressure tank 5 is provided in the main pipe 10 in the related art. When a certain amount of fluid is stored in the pressure tank 5 and a cavity is formed in the main pipe 10 at the time of sudden stop of the pump 2, a part of the fluid stored in the pressure tank 5 is discharged to the main pipe 10 , And when a water impact is generated due to the back flow of the fluid in the main pipe (10), the fluid flows into the pressure tank (5) to mitigate the impact.

A gas supply means 6 such as an air compressor or a nitrogen generator is connected to the pressure tank 5 to supply gas into the pressure tank 5 through the gas supply pipe 6a or to supply an exhaust valve The pressure inside the pressure tank 5 and the water level are adjusted as the gas inside the pressure tank 5 is discharged to the outside.

As described above, the fluid in the pressure tank 5 flows into and out of the pressure tank 5 depending on the state of the piping system. At this time, the amount of fluid flowing out is only a part of the total fluid stored in the pressure tank 5 Therefore, some of the fluid stored in the upper portion of the pressure tank 5 is stagnated for a long period of time in the pressure tank 5 without flowing out. That is, the fluid stored in the upper portion of the pressure tank 5 has almost no flow, and only the fluid in the lower portion repeatedly flows. If the fluid in the upper portion of the pressure tank 5 is stagnated for a long period of time in the pressure tank 5 (for a long period of time), the foreign matter is accumulated in the pressure tank 5, Phenomenon ") occurs. This water degradation is a serious problem if the piping system is a beverage piping system such as tap water or milk. Therefore, there is a demand for a device for discharging the foreign matter stagnated inside the pressure tank 5 to the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the construction and operation of a water piping system having a foreign matter removal function in a pressure tank according to the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments. The water piping system referred to in the present invention includes all kinds of fluid piping systems such as a general water pipeline, circulating piping for air-conditioning and industrial use, an agricultural and industrial water pipeline, a petrochemical plant, and a beverage pipeline.

FIGS. 2A to 2D illustrate various configurations of a water piping system having a function of removing impurities in a pressure tank according to the present invention. As shown, the water piping system according to the present invention includes a fluid discharge pipe 20 inside a pressure tank 5.

2A, the fluid discharge pipe 20 is for discharging the fluid supplied from the outside into the pressure tank 5 to form a vortex. The fluid discharge pipe 20 protrudes from the inner wall of the pressure tank 5 And one end is connected to a fluid supply pipe 30 provided outside the pressure tank 5 and the other end is formed with a discharge port 22 for discharging a fluid into the pressure tank 5. The connection portion between the fluid supply pipe 30 and the fluid discharge pipe 20 of the pressure tank 5 is punctured and the fluid discharge pipe 30 and the fluid discharge pipe 20 are welded Or flanged, or screwed together so as to communicate with each other. In addition, it is preferable that the fluid discharge pipe 20, more specifically, the discharge port 22 is submerged in the fluid (water) stored in the pressure tank 5.

2A, the fluid discharge pipe 20 is vertically protruded from the bottom surface of the pressure tank 5, and the upper end portion is bent in an elbow shape so as to be horizontally disposed inside the pressure tank 5, Direction or downward inclination of the fluid. Although the fluid jet pipe 20 is protruded from the bottom surface of the pressure tank 5 in this embodiment, if the fluid jet pipe 20 can generate a vortex in the pressure tank 5, There is no.

A reducer R having a gradually reduced diameter is formed at an end of the fluid discharge pipe 20 so that the pressure of the fluid discharged from the fluid discharge pipe 20 is increased, 5) to form a stronger vortex. The reducer R may be formed not only at the end of the fluid ejection tube 20 but also at an intermediate portion or the entirety thereof.

The end discharge port 22 of the fluid discharge pipe 20 is preferably arranged in a direction biased from the center of the pressure tank 5 to one side so as to generate a rotational force in the pressure tank 5 . 3, the fluid ejected through the fluid ejection pipe 20 is moved downward in the circumferential direction of the pressure tank 5 to form a vortex, Foreign matter deposited or stagnated inside the tank 5 is discharged through the pressure tank connecting pipe 5a together with the fluid inside the pressure tank 5. [ The drain pipe 50 and the drain valve 52 may be installed on the lower side of the pressure tank 5 to discharge the fluid and foreign matter to the outside through the drain pipe 50. Since the pressure inside the pressure tank 5 is kept constant by the gas supplied by the gas supply means 6, the pressure of the fluid introduced into the pressure tank 5 through the fluid discharge pipe 20 The fluid is discharged through the pressure tank connecting pipe 5a or the drain pipe 50 by an amount corresponding to the quantity of the fluid discharged from the pressure tank 5. At this time, the foreign matter in the pressure tank 5, which has been deposited or stagnated by the eddy current, It is discharged together.

2A, an auxiliary discharge port 24 is additionally formed at a lower side of the fluid discharge pipe 20, more specifically, at a position spaced apart from the discharge port 22 by a predetermined distance H. As shown in FIG. . As a result of the simultaneous ejection of fluid from the ejection orifice 22 and the auxiliary ejection port 24 formed at the upper and lower sides of the fluid ejection tube 20, the eddy currents are formed more easily in the pressure tank 5, Thereby promoting the floating and discharging of foreign matter that has accumulated or stagnated.

2A, the auxiliary discharge port 24 may be formed in the shape of a through-hole formed on the surface of the fluid discharge pipe 20, It may also consist of a tubular body. That is, the auxiliary discharge port 24 is formed at the end of the tubular body protruding and extending from the fluid discharge pipe 20. In this case, it is preferable that the tubular body having the auxiliary discharge port 24 is arranged to be inclined downward to smooth vortex formation, and to float foreign matter deposited on the bottom of the pressure tank 5, thereby smoothly discharging foreign matter.

It is preferable that the diameter B of the auxiliary discharge port 24 is smaller than the diameter A of the discharge port 22. When the diameter B of the auxiliary discharge port 24 is equal to or larger than the diameter A of the discharge port 22, most of the fluid supplied through the fluid supply pipe 30 is ejected from the auxiliary discharge port 24, ). ≪ / RTI > The diameter B of the auxiliary discharge port 24 is larger than the diameter A of the discharge port 22 so that more fluid can be discharged from the discharge port 22 since it is effective to eject the fluid at a higher position in order to form the vortex. It is preferable that it is formed small. The directions of the discharge port (22) and the auxiliary discharge port (24) may be any direction as long as they can form a vortex in the pressure tank (5). Further, when the discharge port 22 and the auxiliary discharge port 24 are formed in the same direction, the effect is better, but they may be different directions.

Fig. 2c shows another structure of the fluid discharge pipe 20. As shown in the drawing, the fluid discharge pipe 20 extends from the side wall of the side wall of the pressure tank 5 and is branched upward and downward into a first branch pipe 20a and a second branch pipe 20b, A discharge port 22 is formed at an end of the branch pipe 20a and an auxiliary discharge port 24 is formed at an end of the second branch pipe 20b. In this case as well, it is preferable that the diameter of the auxiliary discharge port 24 is formed to be smaller than the diameter of the discharge port 22.

In Fig. 2 (d) another structure of the fluid ejection tube 20 is shown. As shown in the drawing, the fluid discharge pipe 20 extends downward from the upper inner wall of the pressure tank 5 and is branched upward and downward into a first branch pipe 20a and a second branch pipe 20b, A discharge port 22 is formed at an end of the first branch pipe 20a and an auxiliary discharge port 24 is formed at an end of the second branch pipe 20b. In this case as well, it is preferable that the diameter of the auxiliary discharge port 24 is formed to be smaller than the diameter of the discharge port 22.

On the other hand, as already mentioned above, the fluid supply pipe 30 is a pipe for supplying the fluid into the pressure tank 5, and at the end, a separate means for providing the fluid to be supplied to the pressure tank 5 should be connected .

Fig. 4 shows a first embodiment using gas supply means 6 provided in the water piping system as such fluid supply means. 4, the fluid supply pipe 30 is connected to a gas supply pipe 6a connecting a gas supply means 6 such as an air compressor or a nitrogen generator and a pressure tank 5, Or the fluid supply pipe 30 may be directly connected to the gas supply means 6. A separate valve 30a is provided in the fluid supply pipe 30 so that the gas generated by the gas supply means 6 can be supplied to the pressure tank 30 through the fluid discharge pipe 20, (Not shown). The valve 30a is constituted by a manual or automatic control valve, and may be manually opened or closed if necessary, or may be controlled to be automatically opened or closed at a predetermined time interval.

Also in this embodiment, it is preferable that the auxiliary discharge port 24 is also provided at the lower side of the discharge port 22 of the fluid discharge pipe 20, and thus the fluid discharge pipe 20 having the auxiliary discharge port 24 The structure may be formed in various structures as shown in FIGS. 2A to 2D.

5 shows a second embodiment of a water piping system according to the present invention using a separate fluid supply means 40. In Fig. 5, the fluid supply pipe 30 is connected to a separate fluid supply means 40, in which the fluid supply means 40 is provided with a gas supply means 6 (Not shown) or a pump (not shown) installed separately from the air compressor (not shown). Compressed air can be supplied into the pressure tank 5 through the air compressor not shown and fresh water or washing water can be supplied into the pressure tank 5 through the pump not shown.

Also in this embodiment, it is preferable that the auxiliary discharge port 24 is also provided at the lower side of the discharge port 22 of the fluid discharge pipe 20, and thus the fluid discharge pipe 20 having the auxiliary discharge port 24 The structure may be formed in various structures as shown in FIGS. 2A to 2D.

6 shows a third embodiment of the present invention. In the third embodiment, the fluid supply pipe (30) is connected to the front end of the check valve (4) of the main pipe (10). Accordingly, the fluid pressurized by the pump is branched from the main pipe 10, is delivered through the fluid supply pipe 30, and is injected into the pressure tank 5 from the fluid discharge pipe 20. Also in this embodiment, it is preferable that the valve 30b is provided in the fluid supply pipe 30 so as to be manually or automatically opened and closed.

Also in this embodiment, it is preferable that the auxiliary discharge port 24 is also provided at the lower side of the discharge port 22 of the fluid discharge pipe 20, and thus the fluid discharge pipe 20 having the auxiliary discharge port 24 The structure may be formed in various structures as shown in FIGS. 2A to 2D.

However, in the present embodiment, in addition to the function of spraying a part of the fluid supplied through the fluid supply pipe 30 into the pressure tank 5, the auxiliary discharge port 24 may check the fluid inside the pressure tank 5 And discharging the gas to the front end of the valve (4).

Generally, when the pump 2 is suddenly stopped, the discharge of the fluid from the pump 2 abruptly stops, so that the pressure on the front end side of the check valve 4 drops. As a result, the disk 4a of the check valve 4 starts to be closed while the fluid flows backward through the check valve 4. [ The disc 4a of the check valve 4 is rapidly closed due to the occurrence of the reverse flow and in this case the formation of the negative pressure at the front end side of the check valve 4 is accelerated and the slam phenomenon of the check valve 4 A phenomenon occurs in which a shock wave is generated due to a "bang" shut off). This slam phenomenon causes damage to the piping system by the shock wave. 7, since the fluid supply pipe 30 is connected to the front end of the check valve 4, a part of the fluid flowing backward from the rear end of the check valve 4 flows into the pressure tank 5 And the fluid stored in the pressure tank 5 is transferred along the fluid supply pipe 30 through the auxiliary discharge port 24 of the fluid discharge pipe 20 and then supplied to the front end side of the check valve 4, Thereby preventing a negative pressure from being generated at the front end of the valve (4) or eliminating the generated negative pressure. Further, the closing speed of the disk 4a of the check valve 4 is reduced, and the slam phenomenon of the check valve 4 is alleviated.

The fluid inside the pressure tank 5 can be supplied to the front end of the check valve 4 through the discharge port 22 of the fluid discharge pipe 20 even if the auxiliary discharge port 24 is not provided, The gas (compressed air or nitrogen) filled in the upper portion of the pressure tank 5 can flow into the main pipe 10 through the discharge port 22 when the water level inside the pressure tank 5 is relatively low, That is, the auxiliary discharge port 24 is further formed at a relatively low position so that only water is supplied to the front end of the check valve 4. [

It is preferable that the fluid supply to the front end of the check valve 4 via the fluid supply pipe 30 at the time of stopping the pump is performed only for a predetermined period of time. If a large amount of fluid is continuously supplied to the front end of the check valve 4 through the fluid supply pipe 30, all the water in the pipe may be backwashed and may lead to on-site flooding or serious accidents. Therefore, it is preferable that the fluid supply to the front end side of the check valve 4 through the fluid supply pipe 30 is temporarily performed only for a predetermined period of time enough to induce the freezing of the check valve 4. Such time may be determined empirically as appropriate values according to the size and operating conditions of the water piping system. In order to supply the fluid to the front end side of the check valve 4 through the fluid supply pipe 30 during the sudden stop of the pump, the valve 30b is automatically closed after a certain time from the stopping point of the pump, Closing valve that gradually closes gradually.

Although the present invention has been described in detail with reference to the embodiments of the present invention, the scope of the present invention is not limited thereto, and the scope of the present invention is substantially equivalent to the embodiments of the present invention.
