Description

本発明は、給水取出し施工における配管テスト用治具に関するもので、水圧テスト用ポンプへの取付け及び取外しがワンタッチで簡単迅速に行えると共に、サイズの異なるバルブの接続口径の相違に一つの部品を基本に使って部品点数を極力少なくして適用でき、且つ用済み後はコンパクトに収納できて破損の原因をなくすことを目的とする。   The present invention relates to a pipe test jig in water supply extraction construction. It can be easily and quickly attached to and detached from a hydraulic test pump with one touch, and one part is basically used for the difference in the connection port diameter of valves of different sizes. It can be used with as few parts as possible and can be stored compactly after use, eliminating the cause of damage.

そして、水道給水取出し施工業務時に実施されている耐圧テストを行なう場合に市販されているテストポンプとの接続にあたり、ネジの種類及びサイズ等の複雑な相違点を一元化して作業性の向上性且つ耐圧テストにおいての高い正確性を提供する。   And when connecting with a commercially available test pump when performing a pressure test that is carried out at the time of tap water supply extraction construction work, it is possible to unify complicated differences such as screw type and size and improve workability and Provides high accuracy in pressure testing.

一般に、この種の配水管から分岐した給水管の水圧をテストするために、市販の水圧テスト用ポンプが用いられている。   In general, a commercially available water pressure test pump is used to test the water pressure of a water supply pipe branched from this type of water distribution pipe.

上記の水圧テスト用ポンプは、水道工事や水道の設置などをしたときに耐圧が十分か、漏れがないかを計測するための装置である。住宅においては、それぞれ水道が設置されるが、そのほとんどは市区町村の自治体からの水道管から受けることになり、そのために工事をして設置をする。設置をしたらそれが正しく使えるか、問題なく施工されているかをチェックする必要があり、そのためにこのテストポンプを使用する。水においては水圧が重要で、それによって家庭内への水の供給力が変わるので、問題ないかをチェックする。そして異常な状態になっていれば施工の段階で漏れが発生している可能性が出てくるので、それを確認する。漏れを発生した後は、修正をした後などにさらにチェックをして確かめることが行われる。   The above-mentioned water pressure test pump is a device for measuring whether the pressure resistance is sufficient or not leaking when waterworks or waterworks are installed. Water is installed in each house, but most of it is received from the water pipes from municipalities in the municipalities. Once installed, it is necessary to check that it can be used correctly and that it has been installed without problems, and this test pump is used for this purpose. In water, water pressure is important, and this changes the water supply capacity in the home, so check if there is no problem. And if it is in an abnormal state, there is a possibility that a leak has occurred at the construction stage, so check it. After a leak occurs, it is checked by checking it further after correcting it.

従来、水道給水取出し施工時等における耐圧テストを行なう場合に使用されているテストポンプの多くは耐圧ホースの長さは1mであり、現場状況によっては耐圧テストの対象物(被テスト管)に届かない場合もあるのが現実である。   Conventionally, most of the test pumps used for pressure test at the time of tap water supply removal construction, etc. have a pressure hose length of 1m, and depending on the situation, it reaches the object of the pressure test (test tube) The reality is that it may not be.

また、その耐圧ホースに取付けられている接続用のネジは、ストレート(以下、「PF」という。)である。PFを使用する場合の利点は、シールテープを使用しなくても取付け取外しが出来るという利点である。   The connecting screw attached to the pressure hose is straight (hereinafter referred to as “PF”). The advantage of using PF is that it can be mounted and removed without using a seal tape.

しかし、昨今においての水道給水取出し施工業務時の耐圧テストは、その対象となる物が作業時に都度発生をするために、耐圧ホース及び取付金具等の取外しの煩わしさを解決する必要性があった。   However, the pressure test at the time of water supply and removal work in recent years has been necessary to solve the hassle of removing pressure hoses and mounting brackets, etc., because the target object is generated each time during work. .

そこで、テストポンプの耐圧ホースの長さを約2mにして耐圧テストの対象物に届くようにすると共に取付け取外しをワンタッチカプラー式にする。さらに、対象物である水道給水止水栓(以下、「Aバルブ」という。)からの耐圧テスト時に
上水ネジ(協会ネジ)及び都ネジ(金門ネジともいう)への接続をカプラー接続するめの治具と止水栓(以下、「Bバルブ」という。)HIVP用への接続及びサドル付分水栓(上水ネジ)用への接続治貝を開発することにある。
Therefore, the length of the pressure hose of the test pump is set to about 2 m so as to reach the object of the pressure test, and the attachment / detachment is made into a one-touch coupler type. Furthermore, when connecting a water supply stop valve (hereinafter referred to as “A valve”), which is an object, to a water supply screw (association screw) and a capital screw (also referred to as a metal gate screw) for coupler connection A jig and a stop cock (hereinafter referred to as “B valve”) are to develop a connection shell for connecting to a HIVP and a water stop cock with a saddle (upper water screw).

上記の特許文献1は、この分野における一般的な水圧テスト用ポンプであり、耐圧ホースの先端を給水管に一端を接続して配管テストをする構造になっている。   Patent Document 1 is a general water pressure test pump in this field, and has a structure in which a pipe test is performed by connecting one end of a pressure hose to a water supply pipe.

ところが、従来の接続方法は、上記特許文献1の水圧テスト用ポンプに付属されている耐圧ホースのストレートネジ部1/4(にぶ)をテーパーネジ1/2(よんぶ)のテスト用メータブッシングのネジへ水道施工業者は、それぞれ部材を調達して接続しているのが実情である。   However, in the conventional connection method, the straight screw portion 1/4 (nib) of the pressure hose attached to the hydraulic pressure test pump disclosed in Patent Document 1 is used as a test meter bushing with a taper screw 1/2 (yongbu). The actual situation is that the water supply contractors procure and connect the respective parts to the screws.

また、上記のように特許文献1の水圧耐圧ホース7の先端に設けられているストレートネジが数多く出まわっている中でストレートネジ部とテーバーネジ部を接続するための部材は特殊であり、調達することが難しいため、ストレートネジとテーバーネジを接続配管してしまうという矛盾が発生しがちであった。   In addition, as described above, a large number of straight screws provided at the tip of the hydraulic pressure-resistant hose 7 disclosed in Patent Document 1 are special, and members for connecting the straight screw portion and the Taber screw portion are special and procured. Because it is difficult, there is a tendency for a contradiction to connect the straight screw and the Taber screw.

そこで、本発明は、テストポンプの耐圧ホースの取付け及び取外しが迅速容易に行えるワンタッチカプラー式にすると共に、当該耐圧ホースを従来の約2mの長さに設定することによって、耐圧テストの対象物(被テスト管)に容易に届くようにすることを目的とする。   Therefore, the present invention is a one-touch coupler type in which the pressure hose of the test pump can be quickly and easily attached and detached, and the pressure hose is set to a conventional length of about 2 m, so that the object of the pressure test ( The purpose is to make it easy to reach the tube under test).
