Summary of the invention
The purpose of this utility model is to provide a kind of reciprocating pump combination brake switch and proporting improving imbibition valve plate sealing and increase the service life.
A kind of reciprocating pump combination brake switch and proporting, comprise imbibition cavity, valve seat and discharge opeing cavity, described imbibition cavity and discharge opeing cavity are arranged on valve seat both sides, described valve seat is provided with imbibing hole and outage, liquid discharging valve guiding is provided with in described discharge opeing cavity, discharge opeing valve plate and liquid discharging valve spring, described liquid discharging valve sleeve-board is contained in liquid discharging valve and leads upper and can slide axially, described liquid discharging valve spring fitting is between discharge opeing valve plate and liquid discharging valve guiding, it is characterized in that, liquid sucting valve guiding is provided with in described imbibition cavity, imbibition valve plate, liquid sucting valve spring and fixing bolt, described liquid sucting valve sleeve-board is contained in liquid sucting valve and leads upper and can slide axially, described liquid sucting valve spring fitting is between imbibition chamber outer wall and imbibition valve plate, described fixing bolt is through liquid sucting valve directed center holes, liquid sucting valve guiding and liquid discharging valve fixed guide are fixed on valve seat both sides by valve base center hole and liquid discharging valve directed center holes respectively, described liquid sucting valve guiding is provided with the through hole corresponding with outage.
The utility model running principle is as follows: when plunger is to left movement, and imbibition valve plate slides axially and lifts off a seat in liquid sucting valve guiding, and imbibing hole is opened; Discharge opeing valve plate and valve seat are fitted, and outage is closed; Medium is flowed in imbibition cavity by imbibing hole.When plunger moves right, imbibition valve plate slides axially and is close to valve seat in liquid sucting valve guiding, and imbibing hole is closed; Discharge opeing valve plate slides axially and lifts off a seat in liquid discharging valve guiding, and outage is opened; The through hole that medium is led by imbibing hole flows in discharge opeing cavity through outage, completes a circulation.Because the guide surface of imbibition valve plate at liquid sucting valve guiding endoporus slides axially; when carrying the medium containing solid particle or foreign material; the particulate being deposited on imbibition cavity bottom can not cause wearing and tearing to slip surface, enhances the sealing of imbibition valve plate, the working life of elongated component.
Further, described imbibition valve plate external diameter is little compared with imbibition cavity internal diameter, is provided with flow channels between described imbibition valve plate and imbibition cavity inner wall.Some solid particles in medium can be deposited in flow channels, and when solid particle is not stacked into guide surface position, guide surface can not cause wearing and tearing, thus extend the working life of imbibition valve plate and the volumetric efficiency of pump.
