Abstract
A liquid purge valve comprising a housing for sealingly fitting at an uppermost end of a substantially vertical pipe, an outlet tube extending from the housing and projecting into the pipe, an outlet port fitted with a sealing boundary and sealable by a sealing member pivotally secured within the housing so as to pivotally displace between a closed and an open position, a biasing member biasing the sealing member into its open position, and a mass articulated to the sealing member and extending downwards into the pipe. The mass applies a force at an opposite direction of the biasing member such that the resultant force acting on the sealing member determines its position such that when water level rises within the pipe the sealing member displaces into the open position.
Claims17
A liquid purge valve accessory comprising a housing for sealingly fitting at an uppermost end of a substantially vertical pipe, an outlet port fitted with a sealing boundary and sealable by a sealing member pivotally secured within the housing so as to pivotally displace between a closed and an open position, a biasing member biasing the sealing member into its open position, said sealing member being fitted with a moment lever articulated at an end thereof distal from said pivot with an arm, whereby said biasing member is articulated at one side thereof and a mass is attachable to another side thereof so as to generate a force at an opposite direction of said biasing member;
- and further the housing is fittable with an outlet tube extendable from said housing and projecting into said pipe.
