Description

Distillation valve protection equipment {PROTECTION FACILITIES FOR WATER GATE VALVE}

The present invention relates to a protection device for a distillation valve, and more particularly, to protect the underground buried distillation valve, which is buried below the ground, and installed thereon to be opened and closed above the ground. It is about.

Referring to FIG. 1, when the dividing valve is installed on the ground or near the ground, the valve cap 6 is provided on the valve seat 5 of the dividing valve 3, and the cavity is inserted into the valve cap 6. Open or close the valve by means of a separate handwheel (7) having a (9), or open and close the valve by a handwheel integrally coupled to the valve seat of the dilution valve (outer thread) For dividing valves of the formula). The underground buried distillation valve mainly uses an external distillation valve, and accordingly, the present invention also relates to a protective device of the internal distillation valve. The valve cap 6 for the threaded dilution valve and the handwheel 7 used therein are standardized in size to open and close a dilution valve of various sizes with one handwheel 7.

In general, a distillation valve protective cylinder is provided above the underground buried distillation valve, and an iron rod is installed in communication with the distillation valve protective cylinder directly above the distillation valve protective cylinder. When opening and closing the dividing valve, the above-described ground handwheel 7 cannot be used as it is, and a long valve opening and closing device is required.

If the depth at which the dividing valve is buried is changed, the height of the dividing valve protection tank and the length of the valve opening and closing device must be changed.

Conventionally, in order to adjust the height of the dire valve protection tank to the depth of embedding of the dire valve, it is necessary to manufacture and use a dire valve protection cylinder of various heights, or to construct the intermediate connecting cylinder by injection molding the upper part of the dire valve protection cylinder integrally with the dire valve protection cylinder. The upper part of the intermediate connecting pipe was cut to fit the embedding depth of the dividing valve. However, manufacturing and using a distillation valve protection container of various heights not only causes excessive production costs, but also has a problem in that the installation depth is slightly different for every distillation valve, so that the height cannot be accurately adjusted. The method of using the intermediate connecting cylinder by injection molding integrally with the dilution valve protection cylinder and cutting the rod to an appropriate length during construction also requires excessive time to install the distillation valve protection facility.

In addition, various attempts have been made in order to adjust the length of the valve opening and closing device to the embedding depth of the dividing valve. An example thereof is disclosed in the Republic of Korea Registered Utility Model Publication No. 20-0177496. The design of No. 20-0177496 "The lower opening and closing rod is inserted into the engaging protrusion of the dividing valve is coupled to the fixing pin, the supporting jaw protrudes on the inner circumferential surface of the upper body, the support disc formed in the through hole in the center of the supporting jaw The upper opening and closing rod, which is installed in the lower opening and closing rod, is installed through the through hole, and the upper opening and closing rod is smoothly lifted in the state inserted in the outer side of the lower opening and closing rod, and the upper opening and closing rod is prevented when the upper opening and closing rod is rotated. A lower opening and closing rod is formed, and support pin insertion holes are formed on the upper and lower sides of the upper opening and closing rod exposed to the upper and lower sides of the support disc, and the upper and lower opening pins are supported by hanging on the support disc by combining the upper and lower support pins. The water valve valve opening and closing device, which is configured to be equipped with a lever for rotating the upper opening and closing rod in the upper insertion hole of the upper opening and closing rod. In this case, the lever is configured such that the working rod is integrally coupled to the lower end of the handle and the fastening portion is coupled to the mounting pin at the lower side of the working rod. The design of No. 20-0177496 has the advantage that the length of the valve opening and closing device can be adjusted by inserting the lower opening and closing rod into the upper opening and closing rod, but forming a through hole in the support disc to open the upper opening and closing rod. After installation through the through-hole, since the lever is inserted into the upper insertion hole of the upper opening and closing rod, there is a problem that a separate lever for the insertion hole of the upper opening and closing rod has to be provided separately. In other words, the above-mentioned groundwater valve handwheel 7 cannot be used in common, and a lever used to be inserted into the upper insertion hole of the upper opening / closing rod must be manufactured separately. In addition, at this time, the upper opening and closing rod is coupled by the upper and lower support pins and the lower support pins from the upper and lower sides while being penetrated through the through holes of the support discs, and thus is supported by the support discs so as to be suspended from the upper support pins during use. There is a fear that the opening and closing rods can flow down.

The present invention devised to solve the above-mentioned problems of the prior art is to provide a distillation valve protection facility that can easily adjust the height of the intermediate connecting tube according to the buried depth of the underground buried distillation valve.

Another object of the present invention is to provide a dilution valve protection device having a structure that can prevent the demounting to be installed on the upper portion of the intermediate connecting barrel sideways.

Still another object of the present invention is to provide a distillation valve protection device having a valve opening and closing device having a structure capable of opening and closing a distillation valve buried underground without providing a separate lever.

Still another object of the present invention is to provide a dilution valve protection device having a valve opening and closing device of an easy installation structure.

Still another object of the present invention is to provide a dilution valve protection device having a valve opening and closing device having an easy rotation structure.

Referring to FIG. 2, the present invention relates to a water dispenser valve 3 provided between water supply pipes 1 embedded underground to block or communicate tap water, and the opening and closing of the water dispenser valve 3 is performed using a valve seat ( It is made by the rotation of 5) as described above. That is, under the valve stem 5, a screw and a valve disc are provided, and the valve disc moves downwards or upwards by the rotation of the valve stem 5, and blocks or communicates tap water. Thus, in order to be able to open and close the dividing valve in the ground above the distillation valve buried in the base, it is provided with a towing 40 and the dividing valve protective barrel 30. In addition, between the pawl 40 and the dividing valve protection barrel 30 is provided with an intermediate connecting cylinder 32 for extending the dividing valve protection cylinder to the pawl 40. The lid 40 is provided with a cover 42, which opens and closes the valve when the valve is opened and closed, and is normally closed.

A feature of the present invention is that the intermediate connecting cylinder 32 is formed by separating from the dividing valve protection cylinder 30, and the intermediate connecting cylinder 32 is inserted into the inner side from the upper end of the dividing valve protection cylinder 30 It is characterized by forming a locking step that can be adjusted to the depth of the intermediate connection cylinder 32 is inserted into the dividing valve protective cylinder 30 on the outside of the dot and the intermediate connecting cylinder 32 that can be formed.

By doing so, it is possible to prevent the iron sheet from deviating laterally during construction or use.

When the dividing valve 3 is buried underground, it is difficult for the arm to extend from the ground to the valve stem 5, so that a separate long opening / closing device is required to open and close the dividing valve 3 from the ground. In addition, the length of the opening and closing device should vary according to the depth of embedding of the fresh water valve, it is preferred that it is always installed in the fresh water valve protection facility.

2 and 4, the valve opening and closing device according to the present invention is a polygonal first rod (10) that is directly coupled by a screw 12 to the upper end of the valve seat 5 of the dilution valve (3) And a second rod 16 having a polygonal hollow in which an upper portion of the first rod 10 can be inserted therein, and a second rod 16 on top of the second rod 16. A valve formed on the second rod support portion 20 and the second rod support portion 20 to be integrally formed with the second rod support portion 16 so as to extend the second rod 16 to the upper surface of the protruding jaw 44 of the pawl 40. It consists of a cap 22. The lower end of the first rod 16 is preferably molded into a box shape so that the lower end of the first rod 16 may be coupled to the valve seat 5, but the body of the first rod 10 does not necessarily need to be a hollow tube. The polygon of the first rod 10 is to allow the first rod 10 to rotate together when the second rod 16 rotates. Since the entire length of the valve opening and closing device can be adjusted by the depth of the first rod 10 inserted into the second rod 16, the length of the valve opening and closing device can be adjusted regardless of the depth of embedding of the dilution valve 3. It can be.

Features of the valve opening and closing device according to the present invention is formed by extending the second rod support portion 20 laterally on the upper end of the second rod (16), so as to be integral with the second rod (16), the second rod ( 16 is prevented from being detached from the support portion 20, and a normal valve cap 22 is provided on the upper surface of the second rod support portion 20, so that the handwheel 7 for the ground-mounted dilution valve is provided. Point to enable opening and closing of the underground buried distillation valve, and a sharp tapered portion 14 is formed on the first rod 10 and the first rod 10 in the hollow 18 of the second rod 16. ) Is easy to insert.

The advantage of the pointed tapered portion 14 formed on the top of the first rod 10 will be apparent with reference to the installation process of the present invention shown in 5a to 5e.

5A to 5E, the installation of the distillation valve protection facility is performed by first coupling the lower end of the first rod 10 to the distillation valve 3 and the valve seat 5 by screws 12 (FIG. 5A). ), The step of fixing the distillation valve protection barrel 30 to it (FIG. 5b), the step of adjusting the height by the locking jaw member 36 by inserting the intermediate connecting cylinder 32 to the distillation valve protection barrel 30 again ( FIG. 5C), the step of securing the claw 40 to the upper flange 34 of the intermediate connecting rod 32 (FIG. 5D) and removing the second rod 16 from the upper opening of the claw 40. 1 is made through the step of inserting the rod 10 sequentially. However, in the last step, it is not easy to insert the upper end of the first rod 10 into the hollow 18 of the second rod 16 because the interior of the intermediate connecting cylinder 32 is dark. The present invention forms a sharp tapered portion 14 on the top of the first rod 10 as shown in Figures 1 and 4, it is possible to easily insert the second rod.
