Description

The present invention relates to a fixed structure and a support for a valve connected to a soft tube.

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

On the other hand, the flexible piping (soft pipe) construction method began to be adopted around 20 years ago for the second part, but the piping construction method has also changed, and the members used have also changed significantly compared to the conventional method.
Looking at the fixed structure of gas plugs, gas plugs dedicated to soft pipes are required, and the types have increased and diversified. In the case of a soft pipe, even if it is fixed to a fixed surface, the gas plug itself is not fixed to the fixed surface or the gas plug is not stable. Therefore, as a gas plug dedicated to a soft pipe, a gas plug with a brim has become common, and a construction method of fixing to a fixed surface with a screw hole provided in a flange portion has become common. More specifically, it is necessary to provide a fixing means for the fixing surface such as the flange part integrally or separately on the gas plug body, and for the fixing surface such as the wall surface or the floor surface, a wood screw or a back is used for the screw hole of the flange part. Construction methods such as tightening and fixing with a plate have been adopted. However, in this construction method, since it is necessary to penetrate the fixed surface such as a wall surface and install it, the piping direction is limited, and it is necessary to devise on-site work, which is different from the case of the conventional steel pipe gas pipe. The current situation is that the cost is higher and the mounting locations are limited.

In Patent Document, the saddle of Patent Document 1 is proposed, but the saddle of Patent Document 1 fixes a soft pipe to a fixed surface, and has a fixed structure of a gas plug (that is, a valve using gas as a fluid). It did not propose a support for fixing the valve.

Jikkenhei 4-27283 Gazette

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

The gas plug is always provided with a multi-faceted portion for spanners that is provided for screw connection to the gas pipe, and valves for fluids other than gas may also be provided with the same multi-faceted portion. There are many.
This polygonal surface portion was used only to receive a reaction force by a spanner hook to prevent co-rotation when the screw was attached to and detached from the pipe. However, the present inventor has made a versatile use of this polygonal surface portion. An invention relating to a valve fixing structure connected to a soft pipe by a new support for fixing the valve itself to a fixing surface such as a wall surface or a floor surface, and a support that can be used for this fixing structure. It is a completed one.

The present invention is a soft tube including a soft tube, a valve connected to the end of the soft tube, a polygonal surface portion provided on the valve, and a support for fixing the polygonal surface portion to a fixed surface of a structure. It proposes a valve fixing structure for pipes. The support has a first portion fixed to the fixed surface and a second portion sandwiching the polygonal surface portion between the first portion. Then, the valve and the pipe end are fixed by fixing the first portion and the second portion to the fixing surface. Therefore, the present invention may be applied to a valve dedicated to a soft pipe having a fixing means, but may also be applied to a valve having no fixing means such as a flange portion used in a conventional steel pipe gas pipe or the like. Can be done.

The first portion is provided with a flat first fixing portion arranged at both ends and a first three-dimensional portion arranged between both first fixing portions, and the second portion is provided at both ends. It can be carried out as having a flat second fixed portion arranged in the above and a second three-dimensional portion arranged between the two second fixed 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. Both are securely fixed to the fixed surface in the state. Then, the first three-dimensional portion includes a first surface corresponding portion along at least two surfaces of the polygonal surface portion, and the second three-dimensional portion includes a second surface corresponding portion along at least two other surfaces of the polygonal surface portion. By providing the valve, the polygonal surface portion of the valve is sandwiched and fixed in a state where rotation is suppressed. As a result, even when a rotational stress is applied to the valve, the force is received by the support fixed to the fixed surface, so that the force is absorbed without applying a load to the connection portion between the valve and the soft pipe. Will be done.

The first three-dimensional portion includes a first rising portion arranged between both ends of the first corresponding portion and the first fixed portions on both sides, and the second three-dimensional portion is the second corresponding portion. It can be carried out as if it is provided with a second rising portion arranged between both ends of the above and the second fixing portion on both sides. The second rising portion is along the outside of the first rising portion, the first corresponding portion is recessed from the upper end of the first rising portion, and the second corresponding portion is the upper end of the second rising portion. The second fixing portion can be reasonably overlapped with the first fixing portion, and both can be fixed to the fixing surface in a state of being overlapped with each other.

The present invention also provides a support used for a fixing structure of a valve connected to the above-mentioned soft pipe. The support has a band-shaped first portion and a strip-shaped second portion as a set of support fittings. The first part is provided with a first through hole, the second part is provided with a second through hole, and the first through hole and the second through hole are configured to coincide with each other in the overlapped state. It is a thing.

The present invention can provide a valve fixing structure for a soft pipe by a new support for fixing a valve such as a gas plug connected to the pipe end of the soft pipe, 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 was a method of fixing the gas plug of the terminal by using a soft pipe, but if the present invention is carried out, the gas pipe can be installed at an arbitrary place and the soft pipe can be connected from that place. The end of the can be fixed. As a result, the piping work for the soft piping can be performed from the fixed end, so that the piping work can be simplified.

2) In the case of gas piping, in the construction of soft pipes, it was necessary to provide the gas plug with a structure for fixing the gas plug such as a gas plug with a brim, but by implementing the present invention, conventionally Even a gas plug that does not have a structure for fixing the gas plug, such as a gas plug for a steel pipe gas pipe, 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 plug is directly fixed and supported on a fixed surface such as a wall surface, no load such as torsional stress or vibration is applied to the pipe screw portion when the gas plug knob is opened / closed. There have been many reports of minute gas leaks from the gas pipe threads around the gas taps of old pipes. It is considered that this is partly due to the above-mentioned load being applied to the pipe thread portion as a result of the gas plug opening / closing operation for a long period of time. It can be suppressed.

4) Gas plugs with various shapes and structures have been commercialized by gas plug manufacturers, but regardless of whether they are wall-mounted or floor-mounted, if the present invention is implemented, they can be used at any location. Can be done.

5) When the gas plugs and valves are attached by carrying out the present invention, the valves are not supported and fixed by the pipe threads, so that excessive tightening torque is not applied to the valves attached to the pipes such as gas pipes. It will be good. As a result, the life of the attached valves can be extended.

6) Piping stress may be applied to the valve body for controlling fluids such as gas due to the influence of bending of the building due to earthquake or vibration, which may cause damage to the valve. By fixing to the fixed surface at the polygonal surface portion located closer to the pipe connection portion than the main body, it is possible to alleviate the action of the pipe stress on the valve main body. As a result, it is possible to suppress the occurrence of breakdowns and accidents such as gas leak accidents due to bending of buildings due to earthquakes and vibrations.

7) The present invention can be used not only for gas taps but also for other valves forming polygonal surfaces such as faucets. By carrying out the present invention, piping by opening and closing the valves The twisting load on the pipe is also reduced, and the effect of reducing the occurrence of leakage from the piping can be expected.
As described above, the present invention exerts various effects, the present invention can be applied regardless of the type of fluid, and the places of use and purposes of use thereof are also diverse.
