Abstract

The invention discloses a novel counter weight type residual pressure valve adopting a movable valve plate and a mounting structure of the novel counter weight type residual pressure valve. The residual pressure valve comprises a top plate, a side plate and a bottom plate, a movable valve plate covers the inner side of a valve port of the bottom plate, the bottom plate is hinged to one end of the movable valve plate, and a heavy hammer moving relative to a hinged shaft is arranged on the movable valve plate. The mounting structure comprises a floor and a wall, a top plate is connected with the floor through a suspender, and side plates are connected with the wall through screws. The method has the beneficial effects that related specifications and technical requirements are met, and a new solution is provided for installation and manufacturing of some special residual pressure valves restricted by the environment; building space is saved, and comprehensive arrangement of indoor pipelines is facilitated.

Description

technical field [0001] The invention belongs to the technical field of building construction, and specifically relates to a novel heavy hammer type residual pressure valve using a movable valve plate and its installation structure, which are suitable for spaces with limited building installation conditions. Background technique [0002] The residual pressure valve used in closed stairwells, smoke-proof stairwells and front rooms is based on the need for a certain positive pressure inside the stairwells and front rooms. When the internal pressure of the stairwells and front rooms reaches a certain value, the residual pressure valve will be in A device that automatically opens under the action of pressure difference to adjust the pressure in the stairwell and front room to meet the pressure difference. Usually, a square hole is made at an appropriate position on the partition wall adjacent to the stairwell and the front room, the partition wall adjacent to the front room and t...
