Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a water control valve housing that protects water control valves such as water pipes buried underground, and a lid provided at the open end of the upper surface of the water control valve housing. It relates to a structure that allows the body to tilt to match the slope of the ground.

[Conventional technology]

Generally, water control valves installed in water pipes are buried underground and protected by a water control valve housing.
In this conventional main water control valve case, for example, a cylindrical case body facing the water control valve is buried vertically in the ground, and the upper opening end of the case body located on the ground surface has a
It has a horizontal structure with a removable lid so that the water control valve can be operated as needed.

[Problem that the invention attempts to solve]

In the above conventional structure, when a water control valve housing with a relatively large diameter is buried on a sloped road, the lid body is horizontal, so the lid body is not flush with the road surface. The upper end of the water control valve housing is
There was a problem in that it had to be located either protruding from the surface of the sloping road or recessed.
If a protrusion or depression is formed on the road near the upper end of the water control valve housing, it will cause a traffic hindrance.

The purpose of this invention is to be able to match the lid body to the sloped ground surface such as the road surface even when buried on a sloped road, and also to be able to accommodate differences in the slope angle of the ground surface. The object of the present invention is to obtain a water control valve housing that can be easily adapted.

[Means for solving problems]

The water control valve casing of the present invention includes a cylindrical casing body, a short cylindrical lid support joined to the top open end of the casing body, and a short cylindrical lid support attached to the top open end of the lid support so as to be openable and closable. The joint surface of the housing body and the lid support is inclined with respect to a plane perpendicular to the axial direction of the housing body, and the lid support has a lower surface that is inclined with respect to the upper surface of the housing body. It is tilted at the same angle as the angle.

[Effect]

In the water control valve housing of the present invention, the upper surface of the cylindrical housing body is inclined with respect to a plane perpendicular to the axial direction of the housing body, and the lower surface of the lid support is at the same angle with respect to the upper surface. When the lid support is joined to the top surface of the housing body, for example, by rotating the lid support body, the lid body provided on the top surface and the housing body can be aligned in the axial direction. The angle formed by the lid body can be adjusted, so that when the housing body is buried vertically in the ground, the lid body can be aligned with the ground surface inclined at an arbitrary angle.

〔Example〕

An embodiment of the water control valve housing of the present invention will be described with reference to FIGS. 1 to 5.

This water control valve housing is used to protect the water control valve 2 of the water pipe 1 buried underground and to enable the water control valve 2 to be operated from the ground.

Reference numeral 11 denotes a receiving plate formed in a substantially annular shape, and is buried horizontally in the ground, with the operating part 4 provided on the upper part of the water control valve 2 located inside the receiving plate.

Reference numeral 13 denotes a housing body, which includes a first substantially cylindrical body 13 supported on the receiving plate 11, and a substantially cylindrical first body 13 that is fitted and connected to the upper end of the first cylindrical body 13. It consists of two cylindrical bodies 14. Note that the lower part of the first cylindrical body 13 has a substantially hemispherical expanded portion 1.
5. And this housing body 12
is located above the water control valve 2 and buried vertically in the ground.

Further, the upper end surface of this housing body 12 is formed into an inclined surface 16 that is inclined at an inclination angle α with respect to a plane perpendicular to the axial direction a of this housing body 12. and,
This inclined surface 16 has a substantially circular shape when viewed from a direction perpendicular to this inclined surface 16. Furthermore, a flange portion 17 is formed on the outer circumferential surface of the housing body 12 below the inclined surface 16, and a plurality of arc-shaped insertion grooves 18 are formed in the flange portion 17.

Reference numeral 21 denotes a lid support body, which is formed into a short cylindrical shape whose lower surface has the same diameter as the upper surface of the housing body 12 and whose diameter decreases upward. The lower surface of the lid support 21 is formed into an inclined surface 22 that is inclined with respect to the upper surface at an inclination angle α that is the same as the inclination angle α of the housing body 12. Further, a flange portion 23 that is joined to the flange portion 17 of the housing body 12 is formed on the outer peripheral surface of the lower end of the lid support 21. For example, eight through holes 24 are formed at equal intervals. Furthermore, an annular stepped portion 25 into which the upper end portion of the housing body 12 is fitted is formed on the inner peripheral edge of the lower surface of the flange portion 13 .

Further, a lid holding part 26 having a substantially L-shaped cross section is formed at the upper part of the inner circumferential surface of the lid support 23, and the top opening 27 of the lid support 21 is formed in this lid holding part 26.
A disc-shaped lid 28 that opens and closes is detachably fitted and held. This lid support 21 is
The flange portion 23 is connected to the flange portion 1 of the housing body 12.
7, and the insertion groove 1 of both flange parts 17, 23
8 and the insertion hole 24, and by tightening the nut 30 to the bolt 29, the lid body 28 is attached to the upper end surface of the housing body 12.
are buried underground so that they are flush with the ground surfaces 31a and 31b.

Incidentally, the upper surface of the casing body 12 is formed as an inclined surface 16 making an angle α with respect to the horizontal plane, and the lower surface of the lid support 21 is formed as an inclined surface 22 inclined at an angle α with respect to the upper surface. Therefore, the first
As shown in the figure and FIG.
When these are joined, the upper surface of the lid support 21, that is, the lid 28 becomes horizontal. On the other hand, Figures 1 and 2
When the lid support 21 is rotated 180° and joined to the housing body 12 with respect to the state shown in the figure, the lid 28 is tilted at an angle of 2α with respect to the horizontal plane.
Since the insertion groove 18 of the housing body 12 into which the bolt 29 is inserted is an arc-shaped groove, the lid support 21 can be joined to the housing body 12 at almost any rotational position. However, this allows the inclination of the lid body 28 with respect to the horizontal plane to be changed substantially continuously from the horizontal state to the maximum inclination angle 2α.

Therefore, the lid body 2 is designed to match the slope of the ground surface 31a, 31b where the water control valve housing is buried.
By adjusting the inclination angle of 8, the lid body 28 can be made to coincide with the ground surfaces 31a and 31b. Moreover, as mentioned above, the inclination of the lid body 28 can be adjusted almost continuously from the horizontal state to the maximum inclination angle 2α.
Ground surface 3 with inclination angle 2α from horizontal ground surface 31a
1b, the lid body 28 can be aligned with the ground surface having any inclination angle within this range.

In addition, instead of the above-mentioned insertion groove 18, eight insertion holes may be formed in the flange portion 17 of the housing body 12 at equal intervals like the lid support 21, but in this case, Housing body 1 overlapped with each other
2 and the insertion hole 24 of the lid support body 21 one by one, the inclination angle of the lid body 28 can be adjusted in five stages.

[Effect of idea]

According to the present invention, the joint surface between the housing body and the lid support is inclined with respect to a plane perpendicular to the axial direction of the housing body,
Since the lower surface of the lid support is inclined at the same angle as the inclination angle of the casing body with respect to its upper surface, for example, by rotating the lid support relative to the casing body buried vertically in the ground, The angle that the lid makes with respect to the horizontal plane can be adjusted, thereby making it possible to match the lid to a ground surface that is inclined at any angle, even if it is horizontal. ,
For example, even if the water control valve housing is buried in a sloped road, no protrusion or depression will be formed near the upper end of the water control valve housing, thereby eliminating the problem of hindrance to traffic.
