Abstract
【課題】既設の浄化槽の放流口の配管内へ地上から簡単に取り付けることのできる逆流防止弁を提供する。【解決手段】先端に向かって外径が小さくなる傾斜面を持ち、後端に係止するフランジを持つ円筒状の本体１と、本体１内にＤ字状の開口部を有する傾斜板と、傾斜板に一端を搖動するように蝶番体で固定されたＤ字状の弁体２からなる。逆流防止弁本体を浄化槽の各規格の放流口配管の内側にはめ込める寸法にすることで、既設の浄化槽に取り付ける。【選択図】図１The present invention provides a backflow prevention valve that can be easily installed from the ground into a pipe of a discharge port of an existing septic tank. A cylindrical main body 1 having an inclined surface whose outer diameter decreases toward the front end and having a flange that is engaged with the rear end; an inclined plate having a D-shaped opening in the main body 1; It consists of a D-shaped valve body 2 fixed with a hinge body so that one end is rocked on the inclined plate. The backflow prevention valve body is attached to the existing septic tank by fitting it into the inside of each standard outlet pipe of the septic tank. [Selection] Figure 1
Description
本考案は、浄化槽の放流口に設置される逆流防止弁に関するものである。The present invention relates to a backflow prevention valve installed at a discharge port of a septic tank.
公共下水道の普及していない地域では、一般家庭の生活排水の処理に浄化槽を使用しており、処理された排水は消毒後に側溝や河川に放流される。台風や、急激な豪雨等により水位が上昇することで、雨水や河川の水が放流配管を通じて浄化槽内へと逆流し、生物反応槽内の担体の流出やマンホールが押し上げられることで地上への汚水の漏出等復旧が困難な状況になる。そこで、処理水の放流口に逆流防止弁を取り付けることで、逆流してくる汚水の侵入を防止する。In areas where public sewerage is not widespread, septic tanks are used to treat domestic household wastewater, and the treated wastewater is discharged into gutters and rivers after disinfection. As the water level rises due to typhoons and sudden heavy rain, rainwater and river water flow back into the septic tank through the discharge pipe, and the sewage to the ground is pushed up by the outflow of the carrier in the biological reaction tank and the manhole. It becomes difficult to recover such as leakage. Then, the invasion of the sewage which flows backward is prevented by attaching a backflow prevention valve to the treated water outlet.
しかしながら既設の浄化槽には逆流防止弁は取り付けられていないため、雨水や河川の水の逆流を防ぐことができない。また、浄化槽は埋設されているため逆流防止が可能な装置を後付する場合は費用が高くなってしまう。
特許文献１や特許文献２に記載されている逆流防止弁では浄化槽の設置後に取り付けることが容易ではない。However, since an existing septic tank is not equipped with a backflow prevention valve, it cannot prevent backflow of rainwater or river water. In addition, since the septic tank is buried, the cost increases when retrofitting a device capable of preventing backflow.
In the check valve described in
本考案では、現在設置されている浄化槽の放流口に簡易的に取り付けることのできる逆流防止弁を提供することを目的とする。It is an object of the present invention to provide a backflow prevention valve that can be easily attached to the outlet of a currently installed septic tank.
前記課題を解決するために本考案に係る逆流防止弁は、浄化槽の放流口の接続された配管の内側にはまる直径をもつ本体１と前記本体内に排水により押し開かれ、排水が逆流してきた場合は閉止することができる弁体２を備え、放流口側のマンホールから取り付けることができることを特徴とする。本体１は浄化槽の各規格に合うように種類をそろえるIn order to solve the above-mentioned problem, the backflow prevention valve according to the present invention has a
本考案に係る逆流防止弁によれば、既設の浄化槽に取り付けることで通常時の浄化槽による排水を阻害することなく、逆流してきた排水のみを閉止することができる効果がある。According to the backflow prevention valve according to the present invention, by attaching to the existing septic tank, there is an effect that only the backflowed wastewater can be closed without hindering the drainage of the normal septic tank.
