Description

Multi-function of Water valve

The present invention relates to a multi-functional distillation valve, and more particularly, by installing a cavitation prevention device in the distillation valve, it is possible to control and remove the cavitation generated by the flow rate of the fluid at the time of opening the disk, and to simplify the porous plate. It is easy to manufacture and install by fastening by structure, and even when the disc is fully opened, a perforated plate is provided at the upper and lower ends of the body to completely control the cavitation generated at the flow rate of a large amount of fluid, and to control the flow of the fluid. Without disturbing, the valve speed indicator is installed on the dividing valve, anyone can know the opening and closing position of the disk of the valve, the valve is convenient to use, and thus very useful in the valve industry, the valve speed indicator One compact unit makes it easy to install on any valve As the rate increases, and the air valve is installed in the distillation valve, when there is a rapid air discharge due to rapid air inflow from the water pipe, there was a problem that the air flow is not smoothly discharged because the float valve blocks the air hole. In the present invention, even if there is a rapid air discharge through the gap between the float valve and the flow valve and the discharge hole of the flow valve is made a continuous discharge, eliminating the case that the air discharge is blocked to discharge the air to leave no water in the water pipe The present invention relates to a multifunctional dehydration valve capable of extending the life of the valve by preventing corrosion of the bolt by transferring the corrosion current acting on the bolt to the sacrificial anode at a speed by providing a corrosion prevention device as the sacrificial anode.

In general, in the water supply or other plumbing facilities buried underground, a distillation valve for opening and closing the flow path is installed at a predetermined distance or at an appropriate location. By moving the disk up and down, the fluid flow is interrupted by the distillation valve.

Here, the water-reducing valve is used to block the pipe for transporting high concentration materials and solids, such as high concentration pulp of paper, sludge of water and sewage, waste transport pipe.

As the driving method of the dividing valve, a manual operation using a handle, an automatic type with an electric motor, and a pneumatic type with an air cylinder are classified.

However, the fluid flowing at high pressure inevitably flows at different opening areas in the valve which regulates the flow to the disk, especially due to the sudden increase in the flow rate in the small opening area when the disk starts to open with the disk closed. The water pressure in the valve is lower than the saturated steam pressure, and at this time, the fluid evaporates and becomes a gas, thereby generating a cavitation phenomenon in which bubbles are generated. The problem of erosion occurs.

In order to prevent such cavitation from occurring, a pressure drop may occur in the valve opening of the valve to prevent the fluid flow rate from increasing, thereby preventing the pressure from dropping below the vapor pressure.

In addition, since the plumbing facility is buried at a predetermined depth in the ground, the dilution valve installed therein is also separated from the ground by a predetermined distance, which makes it difficult to directly adjust the control cap.

In order to solve this problem, the control cap was extended upward from the body of the dividing valve so that it could be positioned as close to the ground as possible, but this also caused the ground surface to be raised due to the overlaying of the road. It was difficult to solve.

Therefore, in order to solve the problem, the control cap is formed to separate the extension tube formed in the upper tube and the inner tube and the inner and outer tubes can be mounted to each of the inner and outer tubes to cope with various heights depending on the degree of overlap of the inner tube. A distillation valve with a structure is provided.

However, the opening and closing operation of the valve has a problem that is very difficult to fit on the top of the valve opening and closing rod installed on the bottom.

In addition, there is a problem that the valve is damaged by applying an excessive torque (Torque) because the controller can not know the current position of the valve and the opening and closing position of the valve, there was a problem that the position of the valve is unknown.

In addition, the body and the extension pipe of the dilution valve that the height of the adjusting cap is stretched are coated to prevent corrosion, but the bolts for joining them do not have a separate coating. The electrolyte is left unprotected.

Therefore, since the bolt has a small electrical resistance, current flows through the electrolytic material, and corrosion occurs by the flowed current, thereby shortening the life of the valve, thereby increasing maintenance costs.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art,

By installing the cavitation prevention device in the water separator valve, it is possible to control and remove the cavitation generated in the fast fluid flow rate when the disc is opened, and to manufacture and install the disc by fastening the perforated plate by a simple structure. Even when fully open, the perforated plate is provided on the inner upper and lower ends of the body to completely control the cavitation generated at the flow rate of a large amount of fluid, and to provide a multifunctional water discharge valve that does not interfere with the flow of the fluid.

In addition, since the valve speed indicator is installed on the dividing valve, anyone can know the opening / closing position of the disc of the valve, and thus the valve is easy to use, which is very useful in the valve industry, and the valve speed indicator is one compact type. Another object of the present invention is to provide a multi-functional distillation valve that can be installed in any unit and can be easily installed in any valve regardless of type, thereby increasing efficiency.

In addition, since the air valve is installed in the distillation valve, when there is rapid air discharge due to rapid air inflow from the water supply pipe, the float valve blocks air holes in the past, but the air is not smoothly discharged. Even if there is rapid air discharge, continuous discharge is made through the gap between the float valve and the flow valve and the discharge hole of the flow valve, which eliminates the case where the air discharge is blocked, so that air can be discharged without leaving the water pipe. It is another object to provide a multifunctional water valve.

In addition, by providing a corrosion prevention device that is a sacrificial anode to the distillation valve, to provide a multi-functional dehydration valve that can extend the life of the valve by preventing the corrosion of the bolt by transferring the corrosion current acting on the bolt to the sacrificial anode in another line. There is this.

In order to achieve the above object, the present invention provides a distillation valve for intermittent flow of the fluid flowing through the body as the disk is moved up, down by a screw,

An air valve installed at an upper side of the body to communicate with the inside of the body and to discharge air in the valve or the pipe to the outside;

The sacrificial anode is connected to the bolt installed in the body to absorb the corrosion current generated from the bolt to prevent corrosion.

As described above, the multi-function distillation valve of the present invention can be removed by controlling the cavitation generated by the flow rate of the fluid at the time of opening the disk, by the installation of the cavitation prevention device, the porous plate by a simple structure It is easy to manufacture and install by fastening, and even when the disc is fully opened, a perforated plate is provided at the upper and lower ends of the body to completely control the cavitation generated at the flow rate of a large amount of fluid and does not disturb the flow of the fluid. Does not work.

In addition, since the valve speed indicator is installed on the dividing valve, anyone can know the opening / closing position of the disc of the valve, and thus the valve is easy to use, which is very useful in the valve industry. It is manufactured in one unit and can be installed on any valve regardless of the type, which increases the efficiency.

In addition, since the air valve is installed in the distillation valve, when there is rapid air discharge due to rapid air inflow from the water supply pipe, the float valve blocks air holes in the past, but the air is not smoothly discharged. Even if there is rapid air discharge, continuous discharge is made through the gap between the float valve and the flow valve and the discharge hole of the flow valve, which eliminates the case where the air discharge is blocked, so that air can be discharged without leaving the water pipe. It works.

In addition, the corrosion prevention device as a sacrificial anode is installed in the dividing valve, it is possible to extend the life of the valve by preventing the corrosion of the bolt by transferring the corrosion current acting on the bolt to the sacrificial anode in a flux.

As shown in Figures 1 to 10, the multi-function distillation valve 10 of the present invention is a flange 22 is formed body 20 is coupled to the pipeline of the fluid transfer pipe, and the disk 30 embedded in the body ), A screw 40 for moving the disk up and down, a cavitation prevention device (not shown) fixed to the outlet of the dilution valve 10 to prevent cavitation phenomenon, and a valve speed indicator (not shown) And an air valve 200 and a sacrificial anode 120.

As shown in FIGS. 1 and 2, the body 20 of the dilution valve 10 has flanges 22 formed at both ends of the pipe body and is coupled with other fluid transfer pipes, and a settling part having a hollow part at the pipe stop portion ( 21) is formed upward. The settled portion is a space in which the disk 30 moved upward to communicate with the tubular body is settled, and the length protruding upward from the pipeline of the body is formed at least greater than the height of the disk to open the tubular body of the fluid ( 30) it is preferable not to disturb the flow of the fluid.

Here, the disk 30 placed inside the body 20 moves up and down by the rotation of the screw 40 to interrupt or open the tubular body. In other words, the disk 30 is moved downward by the screw to block the flow path of the tubular body, and the fluid is interrupted. The disk 30 is usually formed of a circular plate body having a predetermined thickness so that the outer circumferential surface of the disk is in close contact with the pipeline of the body when it is interrupted. Therefore, the disk 30 is formed with guide grooves on both sides of the body 20 in contact with the outer circumferential surface of the disk to prevent being pushed out by the hydraulic pressure, and guide guides on the outer circumferential surface of the disk 30 corresponding to the guide groove ( 31) is formed so that the guide stand 31 is inserted into the guide groove so as to slide up and down to prevent being pushed by the hydraulic pressure.

In addition, the screw 40 has a locking projection 41 is formed along the outer circumferential surface is rotated only about the axis in the same position when a rotational force is applied to the outside. A screw thread is formed on the lower side of the screw 40, and a handle coupling part 42 is formed on the upper side thereof to rotate the screw 40 by the rotational force applied by the handle coupling part. The disk 30 screwed to the 40 is lowered to the upper or lower to open the fluid flow of the tubular body, or the intermittent is made.

That is, the upper end of the settlement portion 21 is opened so that the screw can be mounted, and the settable 23 having a predetermined length is extended in the center direction.

Meanwhile, as illustrated in FIGS. 3 and 4, the disk 30 moved up and down by the rotation of the screw 40 has protrusions 31 formed on both sides thereof to prevent the disk 30 from being pushed by water pressure. A guide groove (not shown) is formed in the inner circumferential surface of the body 20 in contact with the guide stand, and a screw insertion hole 33 is formed in the center thereof, and a screw thread formed on the outer circumferential surface of the screw is formed on the inner circumferential surface of the screw insertion hole. A thread is formed.

In this structure, the disk 30 is formed of a synthetic resin having a material having a constant elastic outer surface to improve watertightness. The synthetic resin generates wear faster than a metal material, so that the guide 31 is guided. As the groove is moved from the groove, wear of the guide guide is rapidly generated.

Therefore, the watertight cap 32 is detachably mounted to the guide stand, which is the portion where the wear occurs, thereby facilitating replacement by wear, and reducing the maintenance cost.

The watertight cap 32 is preferably formed in a size that can cover the front surface of the guide base 31 sliding in contact with the guide groove, reducing the thickness of the guide base 31 by the thickness of the watertight cap 32 Can be installed. Various methods may be used as the mounting means, and typically, a coupling method using protrusions and grooves may be applied.

In addition, the sacrificial anode 120 may include magnesium, aluminum, and zinc, and may be included in the anode body 130 as shown in FIG. 10, and between the anode body 130 and the cathode body 130 is plaster 60 ~ 85%, low internal resistance, 15 to 30% bentonite excellent in ion exchangeability, and the mixture 150 is filled with sodium sulfate 2 to 10% to have a high operating potential can be used even in a high specific resistance environment.

In addition, the body 20 constituting the dilution valve 10 and the bolt 24 for coupling the tubular body and the settled portion 21, respectively, is connected to the sacrificial anode 120 using the wire 140, the wire ( 140 may directly weld the end portion to the bolt 24 or form a coupling terminal (not shown) to fasten the bolt 24.

The sacrificial anode 120 having such a structure is made of a metal having a larger ionization tendency than iron (Fe), which is a material of the bolt 24 for coupling, among the corrosion-resistant distillation valves 10, thereby joining the bolt 24. The bolt 24 is cathodic and the sacrificial anode 120 is polarized so that the corrosion current generated in the bolt 24 flows to the sacrificial anode 120 to prevent corrosion from occurring in the bolt 24.

In addition, the wire 140 that transmits the corrosion current to the sacrificial anode 120 is not limited to the bolt 24, and attaches the coupling terminal of the wire 140 to a portion vulnerable to corrosion in the water valve 10. Can be used in a way.

However, when rapid air is introduced into the inlet hole 211, the float valve 230 is bound to be supported by the air pressure, and when the float valve 230 is floated, the upper flow valve 240 is also supported in the same way, and thus the flow valve ( The upper side of the 240 is in close contact with the O-ring.

At this time, the air flowing into the inlet hole 211 hits the float valve 230 to support the float valve 230, the float valve 230 is the guide hole 231 is fitted into the guide protrusion 245 The guide protrusion 245 is located at one side away from the center and the float valve 230 has a weight, so the float valve 230 is supported in an inclined state to one side, and the float valve 230 is supported by air. By the force that does not block the air hole 251 with the flow valve 240.

That is, when the float valve 230 is moved upward by air, the flow valve 240 is pushed upward, and at the same time the float valve 230 is inclined by its own weight while being fitted to the guide protrusion 245, so the float The valve 230 and the flow valve 240 do not maintain a close contact state, while the float valve 230 maintains the open state while flowing.

Therefore, even though the rapid air flows in the float valve 230 and the flow valve 240 is supported by the upper side of the O-ring and the upper side of the flow valve 240 is in close contact with the air by the force pushing the float valve 230. Since the float valve 230 is inclined due to its own weight and is thus separated between the flow valve 240 and the float valve 230, the air introduced into the inlet hole 211 is the float valve 230 and the flow valve ( In the gap between 240 through the valve seat 242 and the discharge hole 241 is discharged through the air hole 251.

Here, the discharge hole 241 drilled in the flow valve 240 is located inside the O-ring, so that the air discharged to the discharge hole 241 is discharged through the air hole 251 even if the upper surface of the flow valve 240 is in close contact with the O-ring. It will be discharged to the outside.

That is, when rapid air is discharged into the inlet hole 211, when the float valve 230 is supported and the flow valve 240 is in close contact with the O-ring, air may not be discharged to the air hole 251. In the continuous discharge to the discharge hole 241 through the gap between the float valve 230 and the flow valve 240, it eliminates the case that the air is not discharged as before.

Meanwhile, when water is introduced into the body 210 in the present invention, the float valve 230 floats due to water pressure, and the flow valve 240 is in close contact with the O-ring to block air discharge, while the float valve 230 is not tilted. Since the flow valve 240 is pushed upward in the straight state without the valve seat 242 is strongly pressed by the float valve 230, the hole is blocked, thereby eliminating the case where water is discharged to the discharge hole (241). do.

Thus, when the float valve 230 floats in the water and the water inside the water supply pipe is removed while the watertight is maintained, the water inside the body 210 is drained, thereby causing the float valve 230 and the flow valve 240. ) Is lowered, and the external air is introduced into the water supply pipe from the inlet hole 211 after the air through the air hole 251 so that the water inside can be smoothly drained.
