Description

[Detailed description of the invention] [Field of industrial application] This invention is attached to the terminal of one gas hose extended from the main valve, and connects multiple gas hoses extended from multiple gas appliances to this. This invention relates to a gas hose connector that can extend a gas hose and branch the gas hose into a plurality of parts along the way.

[Conventional technology]

Conventional gas hose connectors are used when you want to use multiple gas appliances with a single tap, when the tap is hidden behind furniture and cannot be used effectively, or when you want to connect a long gas hose. It is something that Fig. 3 shows an example in which a gas hose 02 is extended from a main valve 01, and a gas appliance 03 is connected to it using the plug 04 and outlet 05 shown in Fig. 4, and a three-way gas hose 02 shown in Fig. It is an explanatory view when two gas appliances 03 and 03' are used at the same time by attaching a joint 07.

The above conventional example is very convenient in that it allows the gas hose to be extended and two gas appliances to be used, but further improvements are needed in terms of usability and safety. In other words, when the gas hose becomes long, it would be convenient and effective from a safety perspective if it were possible to stop and release the gas not only at the main valve and appliance valve, but also at the joints of the gas hose. It is.
Also, if the main valve does not have an overflow prevention mechanism (fuse valve), the gas hose may come off at the intermediate joint or the connection to the gas appliance.
If the gas hose is cut, gas can leak into the room from the disconnected or cut portion, creating a dangerous situation, so it is also necessary to take measures to prevent such gas leak accidents.

From this point of view, a connector has been proposed in which a gas tank and an overflow prevention mechanism are incorporated (Japanese Utility Model Publication No. 57-150665).

Furthermore, a two-port gas tank is known in which an overflow prevention mechanism is incorporated in each hose connection port (Utility Model Publication No. 57-165860).

[Issues with conventional technology]

However, in the above-mentioned known example,
Although the 150665 connector can extend one hose, it has the inconvenience that it cannot be applied to multiple gas appliances because it branches into two or three branches.

In addition, the two-port gas tank of Utility Model Publication No. 57-165860 is a gas tank that is used by being attached to a wall, etc., so it cannot be used to extend a hose.

The purpose of the present invention is to propose a gas hose connector that is highly safe and easy to use and is used for extending a hose and branching it midway.

[Means to solve the problem]

The configuration of the present invention is as follows.

An inlet side gas hose connection port is formed on the inlet side of the main body that has a gas passage formed inside, and the gas passage is branched into a plurality of branches within the main body to form a branched gas passage, and an outlet side is formed on the outlet side of the branched gas passage. A gas hose connection port is formed respectively, and a closure is built into each branch gas passage, and the closure is configured to be able to be opened and closed by a handle, and the pressure difference between the upstream side and the downstream side of each branch gas passage is greater than a certain level. A gas hose connector characterized in that it incorporates a fuse valve that is activated when the valve seat is in close contact with the valve seat and stops the flow of gas in the branch gas passage.

[Effect]

The above gas hose connector connects the gas hose extended from the main valve to the gas hose connection port on the inlet side.
A gas hose extended from a gas appliance is connected to the outlet side gas hose connection port, and the closure built into the branch gas passage can be opened and closed independently using a handle.

Furthermore, when an excessive outflow phenomenon occurs in each of the branch gas passages, the fuse valve serving as an overflow prevention mechanism comes into close contact with the valve seat due to the pressure difference and stops the flow of gas.

〔Example〕

Fig. 2 shows an embodiment of the present invention, in which 1 is a main body, in which a gas passage 2 is formed, and an inlet side gas hose connection port 3 is provided on the inlet side of this gas passage 2. It is formed. Further, the gas passage 2 is branched in the middle, and plugs 4 and 5 for a gas outlet as an outlet side gas hose connection port are formed on the outlet side of the branched gas passage.

Closers 6 and 7 are respectively incorporated in the branched gas passages leading to the plugs 4 and 5, and the closers 6 and 7 can be opened and closed by a handle 13 and a handle 14, respectively.

8 is a fuse valve as an overflow prevention mechanism built into the closures 6 and 7, and this fuse valve 8
When the amount of gas flowing into the plugs 6 and 7 exceeds a specified value, it comes into close contact with the valve seat 9 and stops the flow of gas. 10 is fuse valve 8
This is a spring for setting the operating flow rate.
In FIG. 1, reference numeral 11 indicates an outlet that can be attached to the plug 4, and 12 indicates an outlet that can be attached to the plug 5. The embodiment shown in FIG. . In the figure, 15 indicates a gas hose.

[Effects of this invention]

As described above, the gas hose connector according to the present invention has a plurality of outlet side gas hose connection ports, each of which has a closure and a fuse valve incorporated therein, so that the following effects can be expected.

a) It is convenient to be able to open and close the gas for each gas appliance at the gas hose connector using the closure.

b. If the gas hose is disconnected or disconnected between the gas appliance and the gas hose connector, the fuse valve operates at the gas hose connector and shuts off the gas, so there is no risk of gas leaking into the room. It's safe.
