Description

Discharge pipe for water tank internal pressure control

The present invention is installed inside the water tank, the opening and closing degree is set, adjusted and fixed in advance, so that the inlet valve can be protected from being damaged by pressure difference before and after the inlet valve of the inlet end of the water tank, and It relates to a pressure regulating discharge pipe installed inside a water tank with excellent productivity.

With the development of building materials and construction technology, the high-rise apartments and commercial buildings continue to increase, and the smooth supply of water supply and hot water supply becomes a problem.

In addition, in a complex water supply pipe network of a mountainous Korean terrain, a high water pressure increases the water leakage of the water supply and causes a decrease in the water supply rate, resulting in water shortage.

In addition, when water is supplied from the high area to the low area, the valves located in the low area, compared to the various valves located in the high area, increase the pressure difference between the front and rear ends. A lot of problems occur that damage and leakage of peripheral devices increase.

Additionally, high flow rates due to high water pressure in low areas can cause noise and vibration in the piping, which can cause more problems.

Accordingly, although a plurality of valve rooms or water tanks are installed between pipes, a part of water is stored and discharged, but this can be controlled more efficiently and effectively to prevent damage to pipes and various devices in advance. There is an urgent need for the development of a device that can be used.

Hereinafter, with reference to Figures 1 to 4 will be described in detail the pressure control discharge pipe installed inside the water tank excellent in assembly and productivity according to a preferred embodiment of the present invention.

The pressure regulating discharge pipe installed inside the water tank having excellent assembly and productivity according to the present invention includes an inlet pipe 11, an inlet valve 20, and an outlet pipe 30.

First of all, the'installation and productivity-type pressure-controlled discharge pipe having excellent assembly and productivity' according to the present invention is installed in the water tank 10, and in such a water tank 10, the suspension is horizontal to the ground and penetrates horizontally. The inlet pipe 11 is installed, and the middle part is bent and installed upright toward the upper portion, and the corresponding end portion of the inlet pipe 11 is installed upright. Of course, the water tank 10 is also provided with a discharge pipe 13 on the opposite side wall where the inlet pipe 11 is formed.

The inlet valve 20 is installed in the inlet pipe 11 outside the water tank 10, and separate pressure sensors 12 are installed at the front and rear ends of the inlet valve 20, and the inlet valve 20 ) The pressure difference between the front and rear ends is transmitted to a separate control unit connected to the water tank 10 or the user is to visually identify it.

Accordingly, the user (or the controller 30) compares the measured pressure difference before and after the inlet valve 20 with the preset pressure difference, and then discharges the discharge to such an extent that the discharge pressure can be the preset pressure difference. The opening amount is controlled by pre-adjusting the position of the disk 45 in the tube 30. Thus, by measuring the pressure difference between the front and rear ends of the inlet valve 20 to be a preset pressure difference, the inlet valve 20 (and peripheral pipes and peripheral devices) is prevented from being damaged by a severe pressure difference.

The discharge pipe 30 is installed in communication with the end of the inlet pipe 11 in the above-described water tank 10, so that the discharge amount of water discharged through the inlet pipe 11 is adjusted and installed in advance. will be.

The discharge pipe 30 for this is composed of a porous cage 32 and a disk portion 40.

The perforated cage 32 is connected so as to communicate with each other at the ends of the inlet pipe 11 described above, and has an empty inside and a cylindrical tube with both ends opened, and a plurality of outlet holes 31 are formed in the periphery of the perforation. It is to be able to discharge water into the water tank 10 through the discharge hole 31.

The disk portion 40 is inserted into the interior of the porous cage 32, so that the pressure difference before and after the inlet valve 20 is a discharge amount that can be a preset pressure difference, in the longitudinal direction of the porous cage 32, The fixed position is set diagonally and fixed by the user in advance. That is, when the position of the disk portion 40 is fixed, the water introduced into the porous cage 32 through the inlet pipe 11, the hole of the porous cage 32 or more than the position of the disk portion 40 ( 31) is to prevent water from being discharged, and if the disc portion 40 is fixed to the middle of the porous cage 32, the water is a discharge hole 31 of the outer circumference of the lower half of the porous cage 32 Water is discharged to the water tank 10 only.

The disk portion 40 for this includes a sliding rod 41, an upper cover 42, an adjusting rod 43, a disc support 44, and a disc 45.

First of all, a ring-shaped plate-shaped flange portion 33 for coupling the sliding rod 41 to be described later is protruded on the outer circumferential edge of the porous cage 32.

The sliding rod 41 is along the circumference of the circumferential surface of the flange portion 33 (in the circumference around the perforated cage 32), a plurality of spaced apart from each other It is a rod that is fixed at one end and installed upright.

The upper cover 42 is a circular plate that is horizontally installed on the upper portion of the porous cage 32, so that the other ends of the plurality of sliding rods 41 are penetrated, so that the plurality of sliding rods 41 are positioned. While being guided, it has a structure capable of adjusting the sliding position up and down toward the longitudinal direction of the sliding rod 41. At the upper end of the upper cover 42, a control rod 43 for a handle use is formed to facilitate adjustment of a fixed position of the upper cover 42. Of course, as for the upper cover 42, as the other ends of the plurality of sliding rods 41 are fitted through, it is natural that a plurality of sliding holes 46 should be perforated at the circumference of the circumferential surface, and the upper cover 42 When the position of the (fixed position of the disk 45 in the perforated cage 32) is fixed, tighten the various fixing members 47 (nuts, etc.) to adjust the preset positions of the upper cover 42 and the disk 45. Just fix it.

The disk support 44 is a hollow tube having an inside formed to protrude on the bottom surface of the upper cover 42, and having a relatively smaller diameter than the above-described porous cage 32, inserted into the porous cage 32 Make this possible.

The disk 45 is a circular plate material that is installed in a form parallel to the ground at the bottom of the disk support 44, and when the upper cover 42 moves up and down, the disk support 44 accompanies it. As it moves up and down, it is inserted correspondingly into the inside of the porous cage 32. The disk 45 has a structure in which the outer periphery is in contact with the inner periphery of the porous cage 32, so that water is not discharged to the upper side of the fixed position.

Of course, for this purpose, in the user or control unit, the disc portion 40 (more precisely, the disc 45) is positioned at any position in the porous cage 32 in accordance with various pressure differences before and after the inlet valve 20. , Although the discharge amount should be positioned to some extent, it is natural that the pressure difference between the front and rear ends of the inlet valve 20 should be known or recorded in advance.

In addition, the perforated cage 32 is formed such that the number of perforations of the discharge holes 31 increases or the size of the perforations gradually increases as it faces the upper portion in the longitudinal direction, according to various embodiments of the user. It is possible to make linear control possible.

As described above, although the present invention has been described by a limited number of embodiments and drawings, the present invention is not limited thereto, and the technical spirit of the present invention and the following will be described by those skilled in the art to which the present invention pertains. Of course, various modifications and changes can be made within the equal scope of the claims to be described.
