The present invention relates to a water dispenser valve applied to pipes for water supply, sewerage and industrial use, and more particularly, by installing a separate valve control unit on a known opening and closing rod for opening and closing a water dispenser valve on the ground regardless of the vertical position of the valve. The present invention relates to a variable valve manipulator of a dilution valve that enables simple and stable operation of the valve.

In general, the distillation valve is a gate valve installed in a pipe buried underground to open and close the flow of water while the valve is raised and lowered by the rotation of the valve rod.

Normally, it consists of a valve body coupled to the pipe buried underground, a valve provided to the valve body to open and close the flow of water, an opening and closing rod for raising and lowering the valve and a handle for rotating the opening and closing rod, the opening and closing rod according to the rotation of the handle Is to raise and lower the valve to open and close the flow of water.

In the underground, water, sewage or industrial plumbing facilities installed in the basement is provided with a dewatering valve for opening and closing of the flow path at each appropriate position to operate the distillation valve in the event of work or disaster caused by construction.

In addition, the conventional dividing valve is operated by opening the index cover of the index retractor on the ground and inserting an operation key or a handle to the opening / closing rod. When the distance from the valve body is far from the opening / closing rod, it is difficult to fit the operation key or the handle. There have been difficulties in valve operation.

Moreover, when the height of the index pullout is positioned higher than usual according to the road maintenance work, the adjustment has been more difficult.

In order to solve such a problem, conventionally registered Patent No. 207419 "Valve Rod Height Adjusting Device" (hereinafter referred to as "1") and Patent Registration No. 542802 "Valve Valve Height Adjusting Device" (hereinafter referred to as 2) And Practical Registration No. 0365948, "Cap Lifting Water Valve" (hereinafter referred to as "3") has been presented and registered.

The well-known valve rod height adjusting device includes a rectangular connecting rod fitted to a coupling part of a dilution valve, a connecting tube inserted in a form surrounding the outside of the connecting rod and fixed to a packing cap of the dividing valve, and an inner side of the connecting rod. It is fitted with a control rod is inserted into the insertion rod formed in the upper projections, the insertion rod is wrapped around the connecting rod and covered with a locking projection of the adjustment rod, and the cover formed with a control cap is inserted into the control rod protruding into the insertion tube Pulling the cover up from the upper control rod is transferred from the inner side of the connecting rod to the top and the insertion tube fitted to the locking projection of the adjusting rod is transferred from the outer side of the connecting tube to the upper structure to freely adjust the height of the adjustment cap.

However, the above structure has a structure in which the outermost insertion tube is rotated at the same time when the adjustment cap is rotated, so that the insertion tube is damaged by excessive rotational force when an interference phenomenon with an external object occurs.

In addition, there is a problem that the insertion tube is a slide up and down through the O-ring with respect to the connection pipe fixed to the valve body there is a problem that generates resistance when the adjustment cap is rotated.

In addition, there is a problem that the connecting rod is rotated when the adjustment cap is rotated and the connecting rod is coupled to the square in a square shape, if excessive rotational force is generated in the adjusting rod, the connecting rod is broken and the bottom of the connecting rod is removed from the coupling part. .

The height adjusting device of the valve rod for the distillation valve of the known 2 is provided with a joint coupling having a connection hole at the lower end so as to be fitted into the engaging portion formed in the valve rod of the dilution valve and to have a hexagonal coupling portion at the upper and inner surfaces thereof. An axial connecting rod on the tube, an outer axial protective tube inserted into the outer axial connecting rod and having a lower end fastened to the packing cap of the dividing valve, and having a dust cover fixed thereon, and inserted into the outer axial protective cylinder and the O-ring to the upper inner surface. An inner shaft protection tube which is fitted and protrudes with a set of spacers facing the lower outer peripheral surface, and a gas cylinder that performs the appearance of the piston rod through the operation of the shaft connecting rod in a state in which the outer peripheral surface is formed in a hexagon and does not rotate; Removably fastened to the upper end of the gas cylinder and each includes a control cap is formed an operation head on the top It was done.

However, the above-described structure, which applies a known gas cylinder to the elevating structure, induces the elevating through the operation pin, but in this case, if the air pressure charged in the gas cylinder is released to the outside due to excessive operation of the operator, There is a problem that the function is lost.

In addition, since the outer shape of the gas cylinder, that is, the hollow pipe outer diameter must be processed into a hexagon, there is a problem that the outer diameter must be unnecessarily increased in order to increase the durability.

In addition, when the inside of the device is corroded inside the shaft connecting portion for guiding the gas cylinder due to water or water leakage, there is a problem that the operator is injured due to malfunction of the operation pin because the gas cylinder is not free to move up and down.

In addition, when opening / closing the dividing valve with the upper operation cap, the operator inserts the operation key into the operation cap, and when the operator applies the force, the direction of force transmission of the operation key is 45 degrees at the same time horizontally and vertically. Forces acting in a vertical manner and transmitted vertically are transmitted to the cylinder rods of the gas cylinders as they are, which imposes loads on the rods, while the diameters of the rods of the gas cylinders are relatively thin, which causes the cylinder rods to be burned out.

In addition, in order to operate the height of the top and bottom, after the installer has been trained in how to use the connection between the operation head and the operation cap, after removing the fixing bolt to adjust the height, it is necessary to tighten the fixing bolt to the operation cap again to fix it. There is a problem being added.

The cap-lifting valve of the well-known 3 has a hexagonal shape on an inner side of a coupling pipe for extrapolating and fixing the valve rod of the dividing valve, and a hexagonal connecting rod is inserted into the inner side to move up and down. An outer protective tube fixed to the cap and fixed to the dividing valve on the outside of the coupling pipe and an inner protective tube provided on the inner side of the outer protective tube and covered with a protective tube cover on the upper side, and the inner and outer protective tubes are fixed with a fixed ring and bolt after height adjustment. It is to be fixed so that the rotational force for rotating the cap can be transmitted to the valve rod.

When the inner protective tube and the outer protective tube is coupled to fix the fixing ring on the upper end of the outer protective tube and the bolt coupled to the fixed ring to support the inner protective tube, there is a weak coupling force.

In addition, when the inner protective tube is separated from the inner circumferential surface of the fixed ring during the lifting operation by the operator, the inner and outer protective tube has a narrow tolerance, there is a problem that reassembly is inconvenient.

In addition, there is a problem that the coupling pipe is rotated in the hexagonal shape when the cap rotates when the coupling pipe is broken when excessive rotation force is generated in the connecting rod.

In addition, the inner and outer protective tube is a structure in which the bolt passing through the outer side of the outer protective tube through the fixing ring is pressed to support the outer side of the inner protective tube. If the back is pinched there is a problem that assembling and lifting is difficult.

Accordingly, the present invention improves on the above-described conventional patent No. 10-542802, No. 20-207419 for Registration Room and No. 20-0365948 for Registration Room.
