Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sluice valve for use in pipelines for agricultural and marine equipment, water treatment equipment, building equipment, plant equipment, water supply, and more particularly, to a sluice valve particularly suitable for underground burial use.

[0002]

[Prior art]

 Conventionally, as a method of burying a sluice valve, for example, as shown in FIG. 4, a concrete plate 11 or the like is installed on the ground to stabilize the sluice valve 10 and connected to the pipe 17 via a joint 10a or the like. Installed a sluice valve 10, backfilled with sand or fine soil 12 by 10 to 15 cm each, tamped with a stick or the like, repeating this, and backfilled until the upper surface of the pipe 17 reaches a minimum of 15 cm. A method of placing 13 on top of each other and installing a valve box, a valve casing, or the like 14 thereon, and a method of installing the sluice valve 10 in the valve box 15 as shown in FIG. 5 are adopted. When performing excavation work in the vicinity of the buried sluice valve 10, it is necessary to confirm the extension direction of the pipeline from the sluice valve 10. In that case, in the case of the construction as shown in FIG. 4, the confirmation is made by the construction drawing, and in the case as shown in FIG. 5, the confirmation is made by the construction drawing or visually from the direction of arrow A.

[0003]

[Problems to be solved by the device]

 However, in the case of visually confirming the pipe direction, the connection position between the gate valve 10 and the pipe 17 could not be confirmed by the burying method as shown in FIG. 4, and even if the shape of the lid was used, the circular shape It was not possible with the sluice valve 10 of the lid. Even with the burying method as shown in FIG. 5, if the sand 16 or the like enters the valve box 15 for a long period of time, the connection between the sluice valve 10 and the pipe 17 is buried, and the direction of the pipeline cannot be confirmed. there were. Therefore, during the work such as excavation work, it is necessary to remove the soil and the like to check the direction of the pipeline, which wastes time and effort, and also causes problems such as damage or damage to the pipe 17. there were. The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is mainly to provide a sluice valve in which the direction of the pipeline of the buried pipe can be easily confirmed.

[0004]

[Means for Solving the Problems]

 For this reason, in the present invention, the inlet main body and the outlet main passage are provided inside the valve main body having the inlet passage and the outlet flow passage, and the valve chamber having a circular cross section provided in the central portion of both of them in the direction perpendicular to the flow passage axis. In a sluice valve having a valve body and a lid that supports a spindle engaged with the valve body, a first feature is that a mark indicating the pipe line direction is provided on the surface of the lid body. The second feature is that the markings indicating the direction of the pipeline are colored vividly.

The material of the sluice valve of the present invention may be metal or plastic and is not particularly limited. In addition, as a method of providing a mark indicating a duct on the surface of the lid of the gate valve, there are various possible methods such as a method of integrally molding, a method of sticking a seal with a mark printed on it, or a method of displaying with paint. good. Also, if this mark is colored in a color different from the color of the lid, it will be easier to confirm, and if it is painted in a bright color with high brightness, it can be clearly confirmed in the dark, and it is effective.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described based on embodiments shown in the drawings, but it is needless to say that the present invention is not limited to the embodiments. 1 is a longitudinal sectional view of a sluice valve showing an embodiment of the present invention, FIG. 2 is a perspective view, FIG. 3 is a plan view of a sluice valve showing another embodiment of the present invention, and FIGS. It is a partial cross-sectional view showing a buried state of the valve.

[0007]

【Example】

 In FIG. 1, reference numeral 1 denotes a valve main body, which has an inlet flow passage 2 and an outlet flow passage 3 therein, and has a circular cross section provided in a central portion of both flow passages in a direction perpendicular to a flow passage axis. It has a valve chamber 4 of. Reference numeral 5 is a valve element that engages with the spindle 6 and moves up and down in the valve chamber 4. Reference numeral 7 denotes a lid body which is fixed to the upper portion of the valve body 1 via a spindle receiver 8 with bolts and nuts (not shown), and supports the spindle 6 engaged with the valve body 5 at its central portion. ing. Reference numeral 9 is a mark that is provided on the surface of the lid body 7 so as to bulge and be integrally formed, and as shown in FIG. 2, apex points in the direction of the inlet flow passage 2 and the outlet flow passage 3 respectively. It is shaped like a triangular arrow. FIG. 3 is a plan view of a sluice valve showing another embodiment of the present invention, in which an arrow, which is a mark provided on the lid, is colored with a yellow fluorescent paint (hatching is used for coloring). I put it).

When the sluice valve of the present embodiment described above is buried as shown in FIG. 4, even if the direction of connection with the pipe 17 cannot be confirmed due to backfilling soil or the like, looking at the mark 9 indicates the direction of the pipe line. You can check. Furthermore, in the burying method as shown in FIG. 5, even when the valve body 1 and the pipe 17 are buried and the connecting direction between the valve body 1 and the pipe 17 cannot be confirmed due to the intrusion of earth and sand into the valve box 15 for a long time. By looking at the mark 9, it is possible to easily confirm the pipeline direction.

[0009]

[Effect of the invention]

 Since the present invention is configured as described above, the direction of the pipeline connected to the sluice valve can be easily confirmed. It is especially effective when used for waterworks and other pipes with buried pipes, where the direction of the pipeline and the position of the pipe can be immediately confirmed on the spot, and when excavating in the vicinity of the valve box or valve casing. It takes less time and effort to check the direction of the road and the position of the pipe, and it is possible to prevent damage to the buried pipe during excavation.
