Abstract

PURPOSE:To aim at remarkably reducing the cost of a system for controlling a gas source valve with the use of signals by integrally incorporating a signal transmitting means with a part of a tube connected to a gas equipment over the overall length thereof. CONSTITUTION:A tube 1 is made of an insulator such as synthetic resin or synthetic rubber. More than one of signal transmitting members 2 are embedded in the tube 1 over the overall length thereof. One end of the tube 1 is connected to a gas apparatus 6 and the other end thereof is connected to a solenoid valve 7. Further, the signal transmitting member 2, the solenoid valve 7 and the apparatus are wired thereamong. A conductor or an optical fiber is selected so as to be used as the signal transmitting member 2. If flammable fluid flows through the tube 1, nonignitingable or nonfiringable ultrasonic signals are transmitted through the signal transmitting member 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gas main valve remote control unit, and more particularly to a gas main valve remote control unit equipped with a tube having a signal transmission means.

[Prior Art] Various types of tubes for circulating gas and other fluids are widely used.

When such a tube is used to transport fluid, various control valves are often used at the front and rear ends or in the middle.

In such cases, if the control valve uses a system that can be controlled by electrical signals, such as a solenoid valve, the signal wires for controlling these solenoid valves are routed along the tube, and the signal wires are A signal was sent through the valve to control the solenoid valve.

[Problems to be solved by the invention] However, when the above-mentioned method is adopted, at least one signal line is laid out in addition to the tube, which is already a nuisance, making the installation work troublesome. The problem was that it not only existed, but was extremely intrusive.

The above-mentioned problems become even more serious when the distance becomes long or, conversely, when the location is extremely narrow.

Furthermore, if the fluid flowing inside the tube is flammable such as city gas or propane gas, there is a serious problem that if a short circuit or spark occurs on the signal line side in the event of a gas leak, it could lead to a major accident. be.

In addition, in order to prevent gas leaks that occur between the main valve and the gas appliance, it is possible to install a main valve one-to-one with the gas appliance and open and close the main valve in conjunction with the valve on the appliance side. This has not been implemented due to wiring problems.

Means for Solving Problem P] ゛-In the present invention, in order to solve the above-mentioned problem, a signal transmission means is integrally provided in a part of the tube over the entire length in the longitudinal direction, and the tube is A structure is adopted in which a signal transmission means and an electrically connected main valve are connected to one end of the valve.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

[First Embodiment] Figures 1 to 3 illustrate the first embodiment of the present invention. In the figures, what is designated by the reference numeral 1 is a tube made of an insulating material such as synthetic resin or synthetic rubber. ing. One or more signal transmitting members 2, in the illustrated example, four signal transmitting members 2 are embedded over the entire length of the tube 1.

For example, a conductive wire or an optical fiber is selected as the signal transmission member 2, and these serve as signal transmission means.

If such a structure is adopted, the signal transmission means can also be installed by simply installing the tube, and all that is left to do is to connect the control valve and other components.

That is, as shown in FIG. 1, one end of the tube 1 is connected to a gas appliance 6, and the other end is connected to a solenoid valve 7.

Then, the electrical work is completed by connecting the signal transmission member 2, the solenoid valve 7, and the plug on the appliance side.

Note that if the fluid flowing in the tube 1 is flammable, the signal transmission member 2 may be loaded with a signal that does not cause ignition, such as an ultrasonic wave, an optical signal, or a radio wave.

[Second Embodiment] FIGS. 3 and 4 illustrate a second embodiment of the present invention. In this embodiment, on the outer peripheral surface of the tube 1,
At least one signal transmission member 3, in the illustrated example, four signal transmission members 3 are attached.

This signal transmission member 3 is coated with a conductive paint or the like over the entire length of the tube 1 by a printing method, a vapor deposition method, or the like.

Even if such a structure is adopted, effects similar to those of the above-mentioned embodiments can be obtained.

Note that in this embodiment, since no optical fiber is used, optical signals cannot be used.

[Third Embodiment] FIG. 5 explains a third embodiment of the present invention. In this embodiment, a signal transmission member 4 is spirally wound around the outer peripheral surface of the tube 1. There is.

The signal transmission member 4 may be wound with a conductive wire, or may be coated with conductive paint by a printing method or the like.

Even if such a structure is adopted, the same effect as the above-mentioned embodiment can be obtained, and when a conductive wire is used, the strength of the tube 1 can be increased and the tube 1 can be constructed so that it will not be crushed even if a person steps on it. can.

[Fourth Embodiment] FIG. 6 explains the fourth embodiment of the present invention. In this embodiment, the outer peripheral surface of the tube 1 is entirely coated, and
A signal transmission member 5 is attached over the entire length.

The signal transmission member 5 may be coated with a conductive paint by a printing method or the like, or by a plating method or the like.

Even if such a structure is adopted, the same effects as those of the above-mentioned embodiments can be expected.

) In each of the above-mentioned embodiments, the signal transmission part j material 2
It goes without saying that tubes 1 to 5 may be arranged in a stacked manner. [Fifth Embodiment] FIG. 8 explains the fifth embodiment of the present invention. A hole 8 is formed by penetrating the peripheral wall in the longitudinal direction, and a filament 9 is slidably passed through the hole 8.

If this filamentous body 9 is a conductor, an electric signal can be carried, but regardless of whether it is a conductor or not, by pulling the filamentous body 9 itself manually or using other means. , the main valve 7 may be configured to open and close.

[Effect] As is clear from the above description, according to the present invention, a structure is adopted in which a signal transmission means is provided in a part of the tube and over the entire length, so that the signal transmission means can be transmitted simply by installing the tube. It is also possible to lay cables, making it extremely effective for systems controlled by signals, and
Significant cost reductions are possible.
