Emergency water supply adapter

Abstract

Traditionally, when a dwelling's water supply piping was damaged, using a shut-off valve with a check valve or a shut-off valve with a secondary valve as an emergency water supply adapter for the secondary water supply piping of a water meter during an earthquake or other event had limitations. Because these valves were originally designed for other purposes, there were problems with the time required for response and assembly. [Solution] The emergency water supply adapter consists of an adapter body 1 that is attached to the main valve of a stopcock A with a secondary valve set on the primary side of a damaged water supply pipe. The water supply pipe is attached to the cover mounting portion 11 at the upper end of the adapter body 1 so that water can be supplied while avoiding the damaged part. In addition, the upper edge of the cover mounting portion of the adapter body and the inner surface of the cover 2 are sealed with a watertight rubber 3 to maintain watertightness.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, since check valves and auxiliary valves are installed in piping for their original purposes, there are limitations to using them as emergency water supply adapters, as described in Patent Documents 1 and 2, for the primary and secondary water supply piping of water meters in the event of an earthquake or other disaster. Given the urgency of the need for emergency water supply, there is a great need for an adapter with a dedicated structure that is suited to the installation environment. Means for solving the invention

[0007] The present invention aims to address the above-mentioned problems and is configured as an emergency water supply adapter equipped with a water supply piping mounting structure that can be interchangeably attached to the upper part of a closed stopcock with a check valve or to the main part of a stopcock with a sub-valve, thereby enabling the formation of a water supply channel that avoids damaged parts or parts where water supply has been interrupted due to construction or other reasons.

[0008] Furthermore, by attaching it to the newly installed stopcock with a check valve as an emergency water supply adapter, it can be used as an emergency water supply adapter to avoid the damaged area if the secondary water supply piping of the water meter is damaged due to an earthquake or if water supply becomes impossible due to the collapse of a dwelling.

[0009] Furthermore, if the product is made from a copper alloy, attaching an emergency water supply adapter to an existing check valve-equipped stopcock will maintain its function as a backflow prevention valve, and it can also be installed as an original component in newly installed products.

[0010] The method of use as a component is as follows: When attaching it to an existing water supply pipe that is damaged, etc., first close the shut-off valve of the check valve-equipped shut-off valve (the auxiliary valve of a shut-off valve with an auxiliary valve), remove the cover part (main valve part), attach the adapter there, and then attach the water supply pipe through the pipe attachment part of the attached adapter so that water can be supplied through the pipe, and then open the shut-off valve of the check valve-equipped shut-off valve (the auxiliary valve of a shut-off valve with an auxiliary valve) so that water can be supplied through the adapter while avoiding the damaged part.

[0011] When attaching this adapter to a newly installed product, the cover of the adapter is removed, and the water supply pipe is connected through the pipe connection part of the attached adapter. By opening the shut-off valve of the check valve-equipped shut-off valve (the auxiliary valve of the shut-off valve with an auxiliary valve), the damaged part is avoided, and water can be supplied through this adapter.

[0012] This adapter consists of an adapter body that is attached to the upper part of a stopcock with a check valve or to the main part of a stopcock with a sub-valve, which is set on the primary side of the damaged section of a damaged water supply pipe. The cover attached to the upper end of the adapter body 1 and the upper edge of the adapter body and the inner surface of the cover are sealed with watertight rubber to maintain watertightness.

[0013] As configured as described above, this adapter maintains its water-stopping function and contributes to the organization of the water supply piping as a water-stopping component. The adapter body consists of a cover mounting section and a covering section, but the shape and structure of both the cover mounting section and the covering section will vary depending on the environment in which they are set.

[0014] For example, if the structure of the covering part is designed to screw into a shut-off valve with a check valve or a shut-off valve with a secondary valve, the adapter body can be easily attached and detached.

[0015] Furthermore, regarding the structure of the covering part, in addition to the screw structure described above, there is also a snap-fit ​​structure, and there are also washing machine hoses that are easily available from dwellings, making it difficult to specifically identify one. The embodiment of the present invention is not limited to specific shapes, but consists of structural aspects related to the setting environment. [Effects of the Invention]

[0016] As described above, the present invention consists of an adapter body that is attached to the upper part of a stopcock with a check valve or the main part of a stopcock with a sub-valve, and a cap that covers the upper end of the body. The upper edge of the adapter body and the inner surface of the cap are sealed with a water-sealing rubber, maintaining watertightness, and thus it can also function as a water-sealing component in water supply piping. [Brief explanation of the drawing]

[0017] [Figure 1] This is a front view showing a cutaway section of a stopcock with a secondary valve, illustrating an embodiment of the present invention. It shows the emergency water supply adapter according to the present invention installed on the primary side stopcock with a secondary valve in the event of a failure on the secondary side, and the main valve section being replaced. [Figure 2] Similarly, this is a front view of a stopcock with a check valve, which has a different structure from the stopcock with a sub-plug according to the present invention, as shown in Figure 1. [Figure 3] Similarly, this is a front view illustrating an embodiment of the present invention, showing a state in which the cover of an existing check valve has been replaced with an emergency water supply adapter according to the present invention installed on the secondary side of a water meter, and the check valve portion has been cut out. [Modes for carrying out the invention]

[0018] The embodiments of the present invention will now be described with reference to the drawings. Figure 1(1) shows an existing shut-off valve A with a sub-valve, with the piping from the water distribution pipe (not shown) to the shut-off valve A with a sub-valve and the piping on the secondary side of the water meter M omitted from the drawing. Figure 1(2) shows the case where the main valve A1 is replaced with the adapter body 1. The adapter body 1 is fitted with a cover 2 and a water-stopping rubber 3, and is attached to the shut-off valve A with a sub-valve at the cover attachment part 12. In Figure 1(2), the sub-valve A2 is closed and the cover 2 and water-stopping rubber 3 are removed, and a water supply pipe (not shown) is attached to the cover attachment part 11 of the adapter body 1, and the sub-valve A2 is opened so that water can be supplied while avoiding the damaged part.

[0019] Figure 2(1) shows an existing shut-off valve with a check valve, with the piping from the water distribution pipe to the shut-off valve B and the secondary piping of the water meter omitted from the illustration. Figure 2(2) shows the case where the cover part B2 of the check valve section B1 is replaced with the adapter body 1. In Figure 2(2), the shut-off valve B4 of the shut-off valve with a check valve is closed, the cover 2 and the water-stopping rubber 3 are removed, and the water supply piping is attached to the cover mounting section 11 of the adapter body 1, and the shut-off valve B3 of the shut-off valve with a check valve is opened to allow water to be supplied while avoiding the damaged part. If the check valve body B4 is not removed, the backflow prevention function can also be maintained.

[0020] Fig. 3(1) shows the case of an existing product that supplies emergency water from inside the meter box E on the secondary side of a water meter with the piping from the water distribution pipe to the stop valve C and the piping on the secondary side of the check valve D omitted. Fig. 3(2) shows the case where the lid part D1 of the check valve part is replaced with the adapter body 1. In Fig. 3(2), the stop valve C is closed, the cover 2 and the water stop rubber 3 are removed, a water supply pipe is attached to the cover mounting part 11 of the adapter body 1, the stop valve C is opened, and water supply can be performed while avoiding the damaged part. The backflow prevention function can also be maintained without removing the check valve body D2. Note that there are various types of check valves, such as ball-shaped ones.

[0021] Since the emergency water supply adapter is configured as described above, in the case of damage or the like to the water supply pipe, etc., the damaged part can be avoided during an emergency, and water supply can be smoothly performed through this adapter.

Industrial Applicability

[0022] The emergency water supply adapter according to the present invention closes the stop valve (sub-stop valve of the stop valve with a sub-stop valve) of the stop valve with a check valve to which this adapter is attached, removes its lid part (main stop valve part), attaches this adapter thereto, and attaches a water supply pipe through the cover mounting part of the attached adapter so that water supply can be performed through the pipe. By opening the stop valve (sub-stop valve of the stop valve with a sub-stop valve) of the stop valve with a check valve, the damaged part can be avoided and water supply can be performed through this adapter. Therefore, it is possible to respond to emergencies such as damage to the water supply pipe, and it has a high utility value in the water supply facility industry.
