Description

PIPE CLEANING VALVE CAPABLE OF DOUBLE WATER GATING}

The present invention relates to a pipe washing valve, and more particularly, to the connection of a water separator valve installed in a water supply pipe network, the introduction of poly pigs into the water supply pipe, the recovery of the poly pick, and the The present invention relates to a tubular washing valve capable of performing a heavy distillation valve function.

One of the most important functions of the water supply pipe network is to pressurize the water produced in the water purification plant at a pumping station and to stably supply water to the home faucet in good condition. It is difficult to supply water in good water quality immediately after the new installation of the water supply pipe, immediately after the repair of the water supply pipe, and immediately after the replacement of the old water supply pipe. In addition, if long-term use of water pipes occurs due to corrosion scale inside the pipes, sediment accumulation or bacterial microorganisms adhere to the long-term attachment, water flow area is reduced and water quality is seriously contaminated. Therefore, it is necessary to clean the water pipes in a timely manner. The washing cycle of the water supply network is different depending on the water quality of the water supply and the flow rate in the pipe depending on the composition of the network, but it is common every two to three years.

The pipe cleaning method includes a flushing method in which a certain section of the water supply network is cleaned by one independent loop and cleaned with water supply of a hydrant, and a section of the water supply network is bundled by a single independent loop. Poly Pig (Polly Pig: US Nap Polypic Co., Ltd.) of elastic material (usually urethane), which is slightly larger than the diameter (usually a diameter of about 30% is mainly used. A pigging method of injecting a brand name, an elastic bullet tube washing tool) and forcing it by water pressure is used. Flushing is a method used to clean tubes that are suspected of bacterial microorganisms in the tube and is free of deposits. Pigging is a method used to clean tubes in which deposits have occurred.

The present invention relates, among other things, to valves that can be used for pipe cleaning by pigging.

Korean Laid-Open Patent Publication No. 1999-0073318 discloses a most commonly used pipe cleaning valve. Korean Patent No. 1999-0073318 solves the problem that the pipe had to be cut in order to inject the polypic into the water supply pipe for the conventional pigging, and is coupled to the conventional distillation valve by a flange and has an opening for inserting a cleaning pig. A pig valve for cleaning is disclosed.

However, according to the invention No. 1999-0073318, there is a disadvantage that the pipe washing section can not be clearly separated from the water supply network. That is, according to the invention No. 1999-0073318, there is always a water separator valve that can open or close the pipe at the upstream side of the pipe cleaning pig valve, and the upstream side of the pig valve in the pig (polypic) injection side. Since there is no big problem because it closes and inserts the pig, the downstream side of the pig collecting valve for the pig collecting side is not blocked, so the pipe washing section is not clearly separated. As a result, when the pigs are collected from the pig recovery-side clean-up pig valve, there is a problem that the cleaning waste liquid generated during the picking process is discharged to the downstream side of the clean-up pig valve without being surely discharged together with the pigs.

In addition, according to the above-mentioned 1999-0073318 invention, there is a disadvantage that the recovery of the pig (polypic) is difficult. The tubular cleaning valve according to the invention has a pig guide protrusion formed at the bottom for easy recovery of the pigs, so that the cleaning pig which has passed through the upstream pipe exits to the opening of the pig valve for the pig collecting side. Although it has a structure, it is difficult for a pig to collect | recover pigs because water flows into the downstream piping side of a pipe valve for cleaning by water.

Conventionally, the dividing valve is installed one by one in a valve chamber or a valve protection box provided at a predetermined distance unit in the water supply pipe network, and when a leak occurs in the water supply pipe network or when a pipe repair or a pipe replacement is necessary, a leaking section, a repair section, or a replacement section is provided. Used to separate from other waterworks networks. However, the conventional valve chamber or the valve protection box is provided with only one dividing valve, so that even if a leak occurs when the valve is closed due to accumulation of sediment under the dividing valve body or wear on the valve disc, There is no way.

The present invention devised to solve the problems of the above-described conventional pipe washing valve is connected to the distillation valve pre-installed in the water supply pipe network, the pipe washing valve having a water separation function that can be clearly separated from the other water pipe network The purpose is to provide.

Another object of the present invention is to provide a pipe washing valve having a water separation function that can remove and remove the remaining cleaning waste liquid remaining on the bottom of the water supply pipe in the pipe washing section after removing the pipe washing section from the water supply network. have.

Still another object of the present invention is to provide a pipe washing valve having a dewatering function which can be easily and surely recovered polypic by connecting with a distillation valve installed in a water supply network.

Another object of the present invention is a pipe washing valve that can block water flowing into a leaking section, a repair section, or a replacement section in a water supply pipe network in the event of a water leak in the water supply pipe, or in the repair of a water supply pipe, or a replacement of the water supply pipe. To provide.

Referring to Figure 1, the body of the tubular washing valve having a dilution function according to the present invention is formed with a polypic inlet tube 1 is open at the top to inject the polypic (symbol 33 of Figs. 4a to 4e) The polypic rotary tube 3 is formed in the lower portion of the polypic inlet tube 1, the inner diameter of which is reduced toward the outside. The inner diameter of the polypic inlet tube 1 is slightly larger than the outer diameter of the polypic, and the polypic rotary tube 3 is formed to have an inner space in which the polypic can sufficiently rotate. The inlet of the polypic inlet 1 is provided with a flange 9 for engaging the lid 29 to be described later.

Features of the present invention further extends one end of the polypic rotary tube (3) to form a valve tube (5) integrally with the polypic rotary tube, and the valve box (7) above the valve tube (5) It is formed. As shown in FIG. 1, the valve box 7 is formed integrally with the valve tube 5 by opening the upper portion of the valve tube 5 and extending the valve tube 5 upward. At the tip of the valve tube 5 is formed a flange 11 which can be connected to a water supply pipe or a short-circuit pipe (joint pipe whose diameter decreases toward one end). The pipe diameter of the valve tube 5 is formed to have a constant inner diameter, the size of the inner diameter is formed to be equal to or larger than the inner diameter of the water pipe connected to. When the inner diameter of the valve pipe 5 is larger than the water pipe connected to the water pipe, the flange 11 is connected to the water pipe at the tip of the pipe. When the inner diameter of the valve pipe 5 is the same as the inner diameter of the water supply pipe is connected to use a polypic having a shrinkage of about 5%, the inner diameter of the valve pipe 5 is larger than the inner diameter of the water supply pipe connected to Polypic with shrinkage around 30% is used. The valve box 7 is a valve box for a gate valve. A valve gate guide 23 is formed continuously to the valve tube 5 and the valve box 7. As shown in FIG. 1, the valve gate guide 23 is formed continuously in part in the valve box 7 and the valve tube 5.

Referring to Figure 2, another feature of the present invention is to form a wastewater discharge port 43 in the bottom height of the inner diameter and the inner diameter of the polypic rotary tube 3 in the lower portion of the polypic rotary tube (3), After washing the pipe by the polypic is to be able to discharge the cleaning waste liquid through the waste water outlet (43). The wastewater outlet 43 is closed during the water passage or during the washing of the pipe by polypic. However, when the cleaning waste liquid is discharged through the wastewater outlet 43, the outlet 37 is opened, and the discharge pipe and the pump are located therein. It is connected to discharge the cleaning waste liquid.

2 and 3, the valve tube 5 and the valve box 7 are inserted with a valve gate 31 having a nut 38 at an upper end thereof, and a screw engaged with the nut 39. ) Is assembled with a valve stem 21 formed therein, a valve cap 19 for inserting a valve key to rotate the valve stem 21 outside the valve chamber, and a valve cover 17. To this end, flanges 13 and 15, which are assembled with each other, are formed at the lower end of the valve box 7 inlet and the valve cover 17, and are fastened with bolts and nuts. As shown in FIGS. 3 and 4E, the valve gate 31 is installed inside the valve tube and the valve box so as to be guided in the vertical direction by the valve gate guide 23, and the polypic 33 is connected to the valve. When passing through the tube, the entire valve gate body is accommodated in the valve box 7 and does not protrude into the valve tube 5. By doing so, the polypic 33 can pass smoothly through the valve tube 5.

The valve box 7, the valve gate guide 23, and the valve gate 31 constitute an integral water dispenser valve integrated with the valve tube 5.

The other side of the polypic inlet pipe 3 also extends outward to form a straight pipe 35, and a flange coupled to a dilution valve (39 in FIG. 4E) provided in the valve chamber at the front end of the straight pipe 35. (37) is formed.

In addition, the inlet of the polypic inlet 1 is covered with a cover 29 provided with a see-through window 27 and a hydrant outlet 25. The operator can determine the degree of washing the tube during the washing through the viewing window (27).

By doing so, a tubular washing valve having a dilution function according to the present invention is completed.

Referring to Figures 4a to 4e will be described a method of use of the present invention having the above-described structure as follows.

First, referring to FIG. 4e, a pipe washing valve having a water separation function according to the present invention is installed in connection with a water discharge valve 39 that is already installed in a water supply network. Close the valve gate 31 of the upstream pipe washing valve (compression or pump station side pipe washing valve: the pipe washing valve shown at the top in FIG. 4E) to distinguish the pipe washing section from other water supply networks (upstream pipe washing valve). The valve gate of is in the state shown in FIG. 4A), and the dilution valve 39 connected to the downstream tube washing valve (aqueous tube washing valve: the tube washing valve shown below in FIG. 4E) is closed. At this time, the fresh water valve 39 connected to the upstream pipe washing valve and the valve gate 31 of the downstream pipe washing valve are opened. This clearly separates the tubing section from the water supply network.

Next, as shown in Figs. 4A to 4C, the polypic inlet 1 of the upstream pipe washing valve is opened, and the polypic 33 is introduced therein, and the polypic in the polypic rotary tube 3 is opened. Rotate the head of 33 to face downstream.

Next, as shown in FIG. 4D, the polypic 33 is pushed into the straight pipe 35 and the dilution valve 39, and the cover 27 of the polypic inlet tube is closed. At this time, since the outer diameter of the polypic 33 to be introduced is larger than that of the straight pipe 35 and the dilution valve 39, and has elasticity, the polypic 33 is press-fitted by an operator when it is introduced into these.

In this state, as shown in FIG. 4E, when the valve gate 31 of the upstream pipe washing valve is opened, the polypic 33 is connected to the water supply pipe under strong water pressure (typically 1 to 3 kg / cm 2). (41) It is propelled while rubbing against the inner surface to remove deposits inside the pipe. At this time, the polypic inlet pipe 1 of the downstream pipe washing valve is opened, and a hose or a discharge pipe is temporarily connected to the polypic inlet pipe 1 to discharge the washing waste liquid and the polypic 33 out of the water supply pipe. do. The discharged cleaning waste liquid is sucked into the tank lorry in a small amount and sent to the sewage treatment plant. In the case of a large amount, the waste liquid is processed through a filter box. Polypic can be used for new pipe, descaling, polishing, etc., and the pipe cleaning is performed once to five times by selecting the required one. In this case, the material and shape of the polypic should be determined according to the degree of pipe deposition.

Next, the wastewater discharge port (reference numeral 43 in FIG. 2) is connected to the wastewater pipe and the pump to drain all the washing waste liquid remaining at the bottom of the water supply pipe 41, the pipe washing valve, and the water discharge valve 39. It is advisable to disinfect the tube with 0.1-1 mg / L chlorine solution prior to draining the rinse waste. At this time, it will be apparent to those skilled in the art that the water valve 39 connected to the valve gate 31 of the upstream pipe washing valve and the downstream pipe washing valve should be closed.

As such, according to the present invention, when used in connection with a previously installed dilution valve, the pipe washing section can be clearly separated from the other water supply pipe network, and the pipe can be washed. Not only can be reliably discharged and removed, but also polypic can be recovered easily and reliably. In addition, when water leakage occurs in the water supply pipe, or in repair of the water supply pipe, replacement of the water supply pipe, etc., water flowing into the water leakage section, the repair section or the replacement section may be doubled.
