Abstract

A találmány tárgya gravitációs megvezetésű fenékszelep,amely függőleges folyadékoszlop lezárására, elsősorban a nemönfelszívó rendszerű szivattyúval, például centrifugálszivattyúvalszerelt kutak szívócsövének leürülés elleni védelmére, szivattyújánakbelevegősödés elleni lezárására alkalmazható. A találmány szerintifenékszelep hengerszimmetrikus kiképzésű szeleptestben (1)elhelyezett, belső íves gyűrűként kiképzett szelepülékre (4)folyadékoszlop hidrosztatikus nyomásával záródó záróelemből (2),továbbá a szeleptestben (1) a záróelem (2) felett elhelyezetthatárolóelemből áll. Jellemzője, hogy a záróelem (2) olyan gömb alakúvagy tengelyszimmetrikus íves test, amelynek belsejében a záróelem (2)geometriai középpontjától adott távolságra nyomatékképző elem (8)helyezkedik el, amelynek sűrűsége nagyobb a záróelemet (2) alkotóanyag sűrűségénél, előnyösen annak legalább ötszöröse. ÓThe subject of the invention is a gravity-driven bottom valve, which can be used to seal a vertical liquid column, primarily to protect the suction pipe of wells equipped with a non-suction system pump, for example a centrifugal pump, against emptying, and to seal the pump against air ingress. The bottom valve according to the invention consists of a closing element (2) located in a cylindrically symmetrical valve body (1) and closed by the hydrostatic pressure of a liquid column on a valve seat (4) designed as an inner curved ring, and a boundary element located above the closing element (2) in the valve body (1). It is characterized by the fact that the closing element (2) is a spherical or axisymmetric curved body, inside which a moment generating element (8) is located at a given distance from the geometric center of the closing element (2), the density of which is greater than the density of the material making up the closing element (2), preferably at least five times that.
