Description

[Detailed description of the invention] This invention relates to a gate valve housing for storing water taps, water stop valves, etc. underground, and in particular, the height of the top surface of the lid holder frame above the housing is adjusted to match the ground surface or road surface of the buried part. The lid body is always placed in the optimum position by adjusting the vertical position.

Although the burial depth of water taps and gate valves is approximately fixed, the height from the ground surface is not necessarily constant at each location due to the topography of the buried part, and for this reason, the gate valve housing also has to accommodate this. However, there is a need for something that can easily and quickly adjust the height as needed.

The present invention was developed in response to such requests, and its features include a female threaded portion on the inner circumferential surface of the outer cylinder, which is installed upright on a pedestal buried underground, and the lid is fitted into it. A male screw part that is screwed into the female thread part is provided on the outer circumferential surface of the inner cylindrical body that can be raised and lowered, and the lid holder frame is attached to the upper end of the body. The lid is adjusted to fit the buried part of the ground or road surface.

Further, in the present invention, the pedestal, outer cylinder, inner cylinder, and lid holder frame are molded separately, and each can be easily and firmly assembled to increase productivity.

Hereinafter, one embodiment of the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows the entire gate valve housing 1 according to the present invention, and the valve housing 1 is composed of a base 2, an outer cylinder 3, an inner cylinder 4 that can be raised and lowered, a lid holder frame 5, and a lid 6.

As shown in FIG. 2, the shape of the pedestal 2 is approximately a hollow conical shape, and a quadrilateral flange 2a is provided on the upper surface of the pedestal 2, and a locking wall 2b that rises low is provided around the flange 2a. This flange part 2a

On the inner peripheral surface of the inner cylindrical body 4 inserted into the outer cylindrical body, a male threaded part 13 having a convex cross section and screwed into the female threaded part 12 is formed in a spiral shape with a pitch corresponding to the female threaded part 12. There is. Therefore, in order to insert the inner cylinder 4 into the outer cylinder 3, the upper opening 3b of the outer cylinder 3 must be
The lower end of the inner cylindrical body 4 is fitted into the inner cylindrical body 4, and in this state, the inner cylindrical body 4 is rotated to screw the female threaded portion 12 and the male threaded portion 13 together.

Outer cylinder 3 and inner cylinder 4 assembled in this way
In particular, be careful not to let dust, sand, etc. get into the gaps between the
A rubber gasket 14 is fitted on the upper outer periphery of the inner cylindrical body since it is often inserted during burying work. Further, if necessary, a sand drainage groove formed by cutting out the convex shape of the screw may be provided in the vertical direction of the female threaded portion 12 on the outer cylindrical inner circumferential surface, so that sand and the like that have entered can fall to the pedestal.

As shown in FIG. 3, a quadrilateral upper flange portion 4a is provided at the upper end of the inner cylindrical body 4, which is inserted as described above and whose vertical position is determined by the screwed state. A similarly quadrilateral flange portion 5a is provided at the lower end, and a downward locking wall 5b is formed around the flange portion 5a.
a into the upper flange portion 4a of the inner cylindrical body 4,
Bolts 9 are inserted into the small holes 15..., 16... drilled in the four corners of both flange parts 4a, 5a, and nuts 10 are screwed onto the lower tips of the bolts 9 to fix them, thereby attaching the lid holder frame to the inner cylinder 4. 5 are connected and the insides are communicated. In addition, the small hole 15 of the flange portion 4a
... may be made into female screw holes so that the bolts 9 can be fixed by simply screwing them in.Furthermore, they may be fixed by welding or the like.

The upper opening 5c of the lid receiving frame 5 has an inclined shape whose diameter gradually increases toward the upper end, and the outer circumferential surface of the lid 6 is also an inclined surface matching the above-mentioned inclination, so that when the lid 6 is fitted into the lid receiving frame 5, both sides The lid body 6 is supported by the inclined surfaces coming into close contact with each other. As shown in FIG. 4, this lid body 6 is provided with a crowbar engagement hole 17 in a part of its circumference into which a crowbar or the like is inserted when opening and closing, and the lower surface of the other side opposite to this engagement hole 17 is provided. A hinge metal fitting 18 is vertically provided on the lid receiving frame 5, and the hinge metal fitting 18 is passed through a U-shaped engagement rod 19 protruding from the inner surface of the lid receiving frame 5. Therefore, since the lid 6 can be rotated vertically around this metal fitting 18, the receiving frame 5 can be opened and closed, and if necessary, the lid 6 can be lifted up and stopped by stoppers 18a provided on the left and right sides of the lower end of the metal fitting 18. When it reaches the engagement rod 19, the receiving frame 5 can be opened by rotating the lid body 6 laterally.

Alternatively, a shallow depression 6a may be provided on the top surface of the lid 6, and this depression 6a may be filled with resin concrete or the like for color display. In this case, if a convex shallow part 6b is provided in an appropriate place, taking into account the design effect,
It is preferable because it prevents slipping and at the same time prevents resin concrete from wearing out.

In order to embed the gate valve housing 1 having such a structure in a desired position where piping is provided, such as a water stop valve, the pedestal and the outer cylindrical body, and the inner cylindrical body and the lid holder frame are joined in advance at each flange portion and bolted. Assemble it firmly, then screw the outer cylinder and inner cylinder together, insert it into the hole in the ground, make the pedestal straddle the underground water pipe, and place the water stopcock etc. inside the pedestal. . In this state, the lid holder frame 5 is rotated so that the height of the lid holder frame 5 and the lid body 6 match the ground surface or the road surface.
It is adjusted by raising or lowering it depending on the screwed state of the outer cylinder body 3. If they match, the rotation may be stopped and the embedding hole may be filled in line with the end surface of the upper opening of the lid receiving frame 5.

Thereby, the gate valve housing 1 can be easily and quickly buried in an optimal state with the lid body 6 aligned with the ground surface or road surface of the buried portion. In other words, even if the depth of the buried hole is slightly different due to differences in the topography of the buried portion, the same gate valve housing 1 can be used without any problem.

As described above, the present invention provides an excellent gate valve housing in which the height of the top surface of the lid holder frame can be adjusted according to the ground surface or road surface of the buried part, and the lid body is always kept in the optimal position. be able to. In addition, when raising the road surface, it can be adjusted by simply breaking up the earth and sand around the lid holder frame.In particular, the inner and outer cylinders of the lid holder frame and the base are connected by a quadrilateral flange. This ensures that rotational force is transmitted, making it not only easy to operate but also strong.

Furthermore, according to the present invention, the pedestal, the outer cylinder, the inner cylinder, and the lid holder frame are molded separately, and the pedestal, the outer cylinder, the inner cylinder, and the lid holder frame are each strengthened by bolts at polygonal flange parts. Since they are connected, it is extremely easy to mass-produce, and when raising the lid, the earth and sand on the outer periphery of the lid holder frame is broken and the lid holder frame is turned, and the inner cylinder body rotates as one unit and becomes detached or becomes unrotatable. This makes the raising work extremely efficient.
