Description

TECHNICAL FIELD The present invention relates to a fixing structure and support for a valve connected to a flexible tube.

Today's buildings have an earthquake-resistant structure, and the construction method has changed greatly compared to the past, and the materials for plumbing work have also changed accordingly. Taking gas construction as an example, steel pipes were often used for gas pipes in the past, but today the construction method has changed to flexible pipes made of stainless steel (soft pipes), and the construction work has been simplified.
Specifically, the conventional method of installing a gas plug (that is, a valve using gas as a fluid) corresponding to a steel pipe is to screw the connection end of the gas plug into the tip of a gas pipe made of steel pipe fixed by a support. was attached. That is, since the gas pipe made of steel pipe is hard, it was not necessary to fix the gas plug itself to the fixing surface by fixing it to the fixing surface.

On the other hand, the construction method of flexible piping (soft pipe) began to be adopted about 20 years ago for the second part, but along with the changes in the piping construction method, the materials used have also changed significantly compared to the past.
Regarding the fixing structure of the gas valve, a gas valve dedicated to soft pipes is required, and the number of types has increased and diversified. Even if the flexible tube is fixed to a fixed surface, the gas plug itself will not be stable unless the gas plug itself is fixed to the fixed surface. For this reason, gas plugs exclusively for soft pipes have become common gas plugs with flanges, and the construction method of fixing them to a fixing surface with screw holes provided in the flange portion has become common. More specifically, it is necessary to provide fixing means for fixing surfaces such as flanges on the main body of the gas valve either integrally or separately. Construction methods such as fastening and fixing with plates have been adopted. However, in this construction method, since it is necessary to install through a fixed surface such as a wall surface, the piping direction is limited, and ingenuity is required for on-site work. The current situation is that the cost is higher than the conventional one, and the mounting locations are limited.

Patent Document 1 proposes the saddle of Patent Document 1. The saddle of Patent Document 1 is for fixing a soft tube to a fixing surface, and has a fixing structure for a gas plug (that is, a valve using gas as a fluid). It did not propose a support for fixing the valve.

An object of the present invention is to provide a valve fixing structure for a soft tube using a new support for fixing a valve such as a gas valve connected to the end of the soft tube, and a support that can be used for this fixing structure. and

A gas valve is always provided with a wrench-mounted polygonal surface for threaded connection to a gas pipe, and valves for fluids other than gas may also be provided with a similar polygonal surface. many.
This polygonal facet was used only to receive the reaction force by using a wrench to prevent co-rotation when the screw was attached to or removed from the pipe.

The valve and the pipe end are fixed by fixing the first part and the second part to the fixing surface. Therefore, the present invention may be applied to valves dedicated to soft pipes with fixing means, but it can also be applied to valves without fixing means such as flanges used in conventional steel gas pipes. can be done.

The first part has planar first fixed parts arranged at both ends and a first three-dimensional part arranged between the first fixed parts, and the second part has both ends and a second three-dimensional portion disposed between the two second fixing portions. In this structure, the second fixing portion is overlapped with the first fixing portion and fixed to the fixing surface, so that the first portion and the second portion sandwich the polygonal surface portion of the valve. are securely fixed to the fixing surface together. The first three-dimensional portion includes first surface corresponding portions along at least two surfaces of the polygonal surface portion, and the second three-dimensional portion includes second surface corresponding portions along at least the other two surfaces of the polygonal surface portion.

INDUSTRIAL APPLICABILITY The present invention can provide a valve fixing structure for a soft tube using a new support for fixing a valve such as a gas valve connected to the end of the soft tube, and a support that can be used for this fixing structure. It is a thing.

By carrying out the present invention, the following effects can be expected.
1) There have been methods of fixing a gas plug at the end of a flexible pipe, but if the present invention is carried out, a gas plug can be installed at an arbitrary location, and the flexible pipe can be connected from that location. can be fixed. As a result, it is possible to perform the plumbing work of the soft pipe from the fixed end, so that the plumbing work can be simplified.

2) In the case of gas piping, it was necessary to provide a structure for fixing the gas plug, such as a gas plug with a flange, to the gas plug in the construction of the soft pipe. Even gas plugs that do not have a structure for fixing the gas plug, such as gas plugs for steel pipe gas pipes, can be used for soft pipe construction. Therefore, even a conventional valve for hard piping can be used for soft piping work.

3) Since the gas valve is fixed directly to a fixed surface such as a wall surface and supported, no load such as torsional stress or vibration is applied to the threaded portion of the pipe when opening and closing the gas valve knob. There have been many reports of minute gas leaks from gas pipe threads around gas valves in old pipes. One of the reasons for this is thought to be that the above-mentioned load is applied to the pipe threads as a result of the long-term operation of opening and closing the gas valve. can be suppressed.

4) Gas cocks with various shapes and structures have been commercialized by various gas cock manufacturers. can do

5) When installing gas cocks and valves by implementing the present invention, since the valves are not supported and fixed by the pipe threads, do not apply excessive tightening torque to the valves attached to the gas pipe or other pipe. It gets better. As a result, it is possible to prolong the life of the attached valves.

6) Due to the deflection of buildings due to earthquakes and vibrations, piping stress is applied to the valve body for controlling fluids such as gas, which may cause damage to the valve. By fixing the valve body to the fixing surface by means of the polygonal surface portion located closer to the pipe connecting portion than the main body, it is possible to alleviate the pipe stress acting on the valve body. As a result, it is possible to suppress the occurrence of failures and accidents such as gas leakage accidents due to bending of buildings due to earthquakes and vibrations.

7) The present invention can be applied not only to gas valves but also to other valves such as faucets having polygonal faces. The torsional load on the pipe is also reduced, and the effect of reducing the occurrence of leakage from the pipe can be expected.
As described above, the present invention exhibits various effects, can be applied to any type of fluid, and has a wide variety of locations and purposes of use.

As a result, the three lower half surfaces of the polygonal surface portion 3 can be followed, and the angle between the slope portion 16 and the bottom surface portion 17 is set substantially equal to the angles of the corner portions of the polygonal surface portion 3.例文帳に追加The bottom surface portion 17 is preferably arranged at a height equal to or higher than the first fixing portion 11 .

The first fixing portion 11 is fixed to the fixing surface 5 and has a first through hole 12 for fixing. The first fixing portion 11 is planar along the fixing surface 5, but it may be somewhat three-dimensional such as by providing ribs, or the fixing surface 5 may be curved. For example, the first fixing portion 11 may also have a curved surface shape corresponding thereto. In addition, although the first fixing portion 11 is directly fixed to the fixing surface 5 in FIG. 1, a spacer may be interposed between the first fixing portion 11 and the fixing surface 5 to adjust the height. do not have.
