Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As depicted in figs. 1 and 2, hydraulic station distribution valve platform of the present utility model comprises: 1 is valve body, and 2 is spool, and 3 is poppet valve core assembly, and 4 is screw plug, and 5 is stop block structure, and 6 is spring, and 7 is fluid passage, and 8 is valve pocket, and 9 is poppet valve core.
Spool 2 is arranged in the middle part of valve body 1 inner chamber, poppet valve core assembly 3 is arranged on two ends in valve body 1 respectively, spool 2 and poppet valve core assembly 3 are connected, screw plug 4 is arranged on valve body 1 port respectively and is socketed with poppet valve core assembly 3 and coordinates, screw plug 4 stretches into valve body 1 one end and has inner chamber, and poppet valve core assembly 3 is socketed the inner chamber of screw plug 4 and by spring 6 and screw plug 4 resilient engagement, screw plug 4 inner chamber is provided with stop block structure 5, spring 6 is socketed stop block structure 5, and poppet valve core assembly 3 is socketed with stop block structure 5 and coordinates; Be provided with fluid passage 7 in valve body 1, stop block structure 5 is quality of rubber materials.Poppet valve core assembly 3 includes valve pocket 8 and poppet valve core 9, and poppet valve core 9 is socketed valve pocket 8, and valve pocket 8 is socketed with valve body 1 and screw plug 4 respectively and coordinates, and poppet valve core 9 is socketed stop block structure 5.Be provided with O RunddichtringO between valve pocket 8 and valve body 1, make sealing effect better.Be provided with O RunddichtringO between screw plug 4 and valve body 1, make sealing effect better.Fluid passage 7 is symmetrically distributed in spool 2 both sides.
The hydraulic station distribution valve platform of the present embodiment in use, liquid enters 7 pairs, fluid passage poppet valve core 9 and produces a pressure, the distortion of poppet valve core 9 extrusion spring 6 is subjected to displacement, thus poppet valve core 9 is subjected to displacement, flow out in the gap that liquid produces further by poppet valve core 9 and valve body 1 inner chamber, whole process because of spring 6 strength larger, long-time use can cause non-recoverable deformation to spring 6, stop block structure 5 is certain deformation quantity for quality of rubber materials has, available buffer is to the active force of spring 6, extend the working life of spring, whole hydrovalve within is kept normally to use, matching relationship between this outer valve sleeve 8 and poppet valve core 9, make internal structure more firm, can avoid between poppet valve core 9 with screw plug 4, directly coordinating the comparatively thin tail sheep variable quantity occurred, make the work that poppet valve core 9 energy is stable further.
The simple volume of hydraulic station distribution valve platform structure of the present utility model is little, several functions can be implemented, Stackable type, working efficiency is high, internal structure is comparatively firm, and stop block structure available buffer carries out a definite limitation to the effect of spring force and to hydraulic pressure, extends the working life of hydrovalve, easy to use, meet the demand of people.
