Abstract

【課題】使用した水道水の水量を計量するための量水器は計量費であるため、使用期限が定められているが、この使用期限直前の取替を要する量水器の数も多いため、これを期限内に迅速に取替作業が行われているが、水流の方向をあらわす矢印（１６）は薄く小さくて見落としやすい。
【解決手段】量水器の本体（２）に、しるし（６）を設け、量水器に接続する量水器継手（８）に、しつし（６）を設けることを特徴とする、量水器の逆取付予防装置である。
【選択図】図４[PROBLEMS] A meter for measuring the amount of tap water used is a metering cost, so that the expiration date is set. However, there are a large number of water meters that require replacement immediately before this expiration date. The replacement work is performed quickly within the time limit, but the arrow (16) indicating the direction of the water flow is thin and small and easily overlooked.
An indicator (6) is provided on a main body (2) of a water meter, and a basin (6) is provided on a water meter joint (8) connected to the water meter. This is a device for preventing reverse installation of a water meter.

Description

本考案は、水道水を供給する給水管（１０）の途中に取り付けて、使用した水道水の計量を行うもので量水器逆取の付防止装置に関するものである。This invention is attached to the middle of the water supply pipe (10) which supplies a tap water, and measures the used tap water, and is related with the attachment prevention device of a water meter reverse take-up.

従来の量水器は、図１のごとく、円筒形をした本体（２）の水源側（１１）と、流末側（１２）に、そてぞれ捻子（１７）が付けてある筒（３）と、横付筒補強板（２０）と竪付筒補強板（２８）が付けてあり、本体（２）には本体（２）の流末側に向かって左側（３９）と右側（４０）には、水流をあらわす矢印（１６）が薄く小さく付けてある。
また量水器は計量器であるため、使用期限が決められている。したがって使用期限が切れる直前の量水器もまた数多くあり、そのため使用期限直前の量水器は一斉に迅速に取替られる、そのため量水器のどの部分が水源側（１１）で、どの部分が流末側（１２）であるかは、ただ一見しただけでは容易に見分けが付かないばかりか、本体（２）の両側にあり水流をあらわす矢印（１６）も小さくて薄く付けてあるため充分確認する必要があるが、これを急ぐあまり確認を怠りやすく、また図７のように量水器は片手で持って取り付けるため、この時点でも矢印（１６）は確認できないから逆に取り付けることもおこる、したがって逆に取り付けた量水器はその場では判明することが少ないため、これが判明すたきは次に行われる検針のときになるから、この時点で、再度取付が行われている。As shown in FIG. 1, the conventional water meter is a cylinder (1) and a flow end side (12) of a cylindrical main body (2) each having a screw (17). 3), a horizontal tube reinforcing plate (20) and a flanged tube reinforcing plate (28) are attached, and the main body (2) has a left side (39) and a right side ( 40), an arrow (16) representing a water flow is thinly and smallly attached.
Moreover, since a water meter is a measuring device, the expiration date is decided. Therefore, there are also many water meters immediately before the expiration date, so the water meters immediately before the expiration date can be quickly replaced all at once, so which part of the water meter is on the water source side (11) and which part is Whether it is the end of the flow (12) is not easily identified at first glance, and the arrows (16) on both sides of the main body (2) indicating the water flow are also small and thin, so it is fully confirmed. It is necessary to do this, but it is easy to neglect the confirmation too much in a hurry, and since the water meter is attached with one hand as shown in FIG. 7, the arrow (16) cannot be confirmed even at this point, so it can be attached in reverse. Accordingly, since the attached water meter is rarely found on the spot, this is determined at the time of the next meter reading, so that the fitting is performed again at this point.

そのために次のような問題点があった。
（イ）量水器は図１のごとく本体（２）の水源側（１１）と流末側（１２）には同型の筒（３）が付けてあり、筒（３）の先にも同径の捻子（１７）が付けてあるが水流をあらわす矢印（１６）が流末側に向かって本体（２）の左側（３９）と右側（４０）に付けてあっても、この矢印（１６）は小さくて見落としやすい、また都市には人口が多いため量水器の数も多く、給水管（１０）の途中に取り付けてあるが、この量水器は計量器であるため、使用期限が切れる直前に数多くを期限内に迅速に取り付が行われてる。
（ロ）したがって量水器を取り付ける際は図７のごとく、量水器を上から片手（２５）にて持って取りつけるため水流をあらわす矢印（１６）は見えなくなる。
（ハ）また取り付けた直後も図６のごとくこの量水器を上から見下ろすことになり、矢印（１６）は見えないため、ここでも正しく取り付けたことも確認できないため、しばしば逆に取り付けることがおこる、またこの量水器を逆に取り付けたときは正しい計量は行われなくなる、したがってこの検針は後日行なわれるため、ここで再度取替作業が行われる。
本考案は、以上の問題点を解決するためになされたものである。Therefore, there were the following problems.
(Ii) The water meter is provided with a cylinder (3) of the same type on the water source side (11) and the flow end side (12) of the main body (2) as shown in FIG. Although the diameter screw (17) is attached, even if the arrow (16) representing the water flow is attached to the left side (39) and the right side (40) of the main body (2) toward the flow end side, this arrow (16 ) Is small and easy to overlook, and because there are many populations in the city, there are many water meters, and they are installed in the middle of the water supply pipe (10). Just before it runs out, many are installed quickly within the deadline.
(B) Therefore, when the water meter is attached, as shown in FIG. 7, since the water meter is mounted with one hand (25) from above, the arrow (16) representing the water flow is invisible.
(C) Immediately after installation, as shown in FIG. 6, this watering device is looked down from above, and the arrow (16) cannot be seen. If the water meter is installed in the reverse direction, correct metering will not be performed. Therefore, since the meter reading is performed at a later date, the replacement work is performed again.
The present invention has been made to solve the above problems.

Means that the device tries to solve

量水器の本体（２）にしるし（６）を設け、量水器に接続する量水器継手（８）に、しるし（６）を設けることを特徴とする、量水器の逆取付予防装置である。 Preventing reverse installation of a water meter, characterized by providing an indicator (6) on the main body (2) of the water meter and providing a mark (6) on the water meter joint (8) connected to the water meter Device.

Effect of device

以上の構造であるから、図８のごとく、本考案の量水器（１）を取り付ける際には、あらかじめ矢印（１６）の方向の確認を忘れても、しるし（６）が付けてある筒（３）を、しるし（６）が付けてある量水器継手（８）にあてがって取り付けることにより量水器（１）は正しく取り付けることができる、
また片手（２５）で量水器を持っ取り付けるときでも、図９のごとく、逆に取り付けようとすることがただちに判明し逆取付を未然に防止することができる、
また図１２のごとく、矢印（１６）の確認を怠り、これを取り付けた後直立して量水器を上から見下ろしたときでも、正しく取付たことがこの時点でも判明し逆取付を未然に防止することができる。Since it is the above structure, as shown in FIG. 8, when attaching the water meter (1) of the present invention, the cylinder with the sign (6) is attached even if the direction of the arrow (16) is forgotten in advance. The water meter (1) can be correctly attached by attaching (3) to the water meter joint (8) to which the mark (6) is attached.
In addition, even when holding the water meter with one hand (25), as shown in FIG. 9, it is immediately found that it is going to be attached in the reverse direction, and the reverse attachment can be prevented in advance.
In addition, as shown in FIG. 12, even when the arrow (16) is neglected and it is installed and standing upright and looking down on the water meter from above, it is found that it has been installed correctly at this point in time and prevents reverse installation. can do.
