Abstract
The utility model relates to a hydraulic valve, in particular to a replenishing valve of a hydraulic press, which comprises a valve block and a valve core. The replenishing valve of the hydraulic press is characterized in that a plunger piston is arranged in the valve block; an end cover is placed at the upper part of the valve block by a bolt; a hydraulic control port which is coaxial with the plunger piston is arranged in the end cover; a valve seat in the axial direction the same as the plunger piston is arranged at the lower part in the valve block; an adaptive valve core is arranged in the valve seat; a liquid flow passage communicated with the upper space of the valve core is arranged at the side part of the valve block; the surface of the outer side of the valve seat is provided with a return spring for supporting the plunger piston; a push rod positioned at the upper side of the valve core is arranged in the valve seat; the push rod is higher than the valve seat; and a liquid flow hole is arranged in the valve seat at the side part of the valve core. Therefore, the replenishing valve of the hydraulic press has a simple structure and a reasonable design.
Description
(1) technical field
The utility model relates to a kind of hydrovalve, and particularly a kind of hydraulic press dashes the liquid valve.
(2) background technique
Hydraulic press oil cylinder piston bar descending fast generally leans on gravity to realize that the flow of pump can not be satisfied the demand far away; Must be in master cylinder a large amount of repairings; This often will use liquid-filling valve, now our liquid-filling valve of using because its structural limitations, runner is not smooth; The flow liquid resistance ratios is bigger, and framework is compact inadequately.
(3) summary of the invention
The utility model is in order to remedy the deficiency of existing technology, and what a kind of simple in structure, practical and convenient hydraulic press was provided dashes the liquid valve.
The utility model is realized through following technological scheme:
A kind of hydraulic press dash the liquid valve, comprise valve piece and spool, it is characterized in that: be provided with plunger in the said valve piece, valve piece top is equipped with end cap through bolt, is provided with the hydraulic control mouth coaxial with plunger in the end cap; The bottom is provided with and the coaxial valve seat of plunger in the said valve piece, is provided with suitable spool in the valve seat; Said valve piece sidepiece is provided with the liquid chunnel that is communicated with the spool upper space; Said valve seat outer surface is provided with the Returnning spring that supports plunger; Be provided with the push rod that is positioned at the spool upside in the said valve seat, push rod is higher than valve seat; Be provided with liquid flow hole in the said spool sidepiece valve seat.
The beneficial effect of the utility model is: the hydraulic press of this model utility to dash the liquid valve arrangement simple, the valve seat indoor design is reasonable, the flow liquid resistance is little; Runner is unobstructed; The pressure ratio of control is low can to increase the reliability that resets, and structure is also compact, is suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the cross-sectional view of the utility model;
Among the figure, 1 valve piece, 2 plungers, 3 bolts, 4 end caps, 5 hydraulic control mouths, 6 valve seats, 7 spools, 8 liquid chunnels, 9 Returnning springs, 10 push rods, 11 liquid flow holes.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises valve piece 1 and spool 7, and it is characterized in that: be provided with plunger 2 in the said valve piece 1, valve piece 1 top is equipped with end cap 4 through bolt 3, is provided with the hydraulic control mouth 5 coaxial with plunger 2 in the end cap 4; The bottom is provided with and plunger 2 coaxial valve seats 6 in the said valve piece 1, is provided with suitable spool 7 in the valve seat 6; Said valve piece 1 sidepiece is provided with the liquid chunnel 8 that is communicated with spool 7 upper spaces; Said valve seat 6 outer surfaces are provided with the Returnning spring 9 that supports plunger 2; Be provided with the push rod 10 that is positioned at spool 7 upsides in the said valve seat 6, push rod 10 is higher than valve seat 6; Be provided with liquid flow hole 11 in the said spool 7 sidepiece valve seats 6.
Adopt the utility model hydraulic press dash the liquid valve, during use, valve piece 1 is fixed on the master cylinder; Spool 7 bottoms and master cylinder inner chamber are connected; Make the liquid chunnel 8 of valve piece 1 connect fuel tanks, hydraulic control mouth 5 connects control hydraulic oil, when main oil cylinder piston quick when descending; Spool 7 is opened under the suction function in master cylinder, and a large amount of hydraulic oil can replenish and get in the master cylinder in the fuel tank; When master cylinder was in high pressure conditions, spool 7 was in closed condition, and can pour control hydraulic oil this moment from hydraulic control mouth 5; It is descending to promote plunger 2; The plunger 2 descending promotion push rod 10 descending spools 7 of opening, in-oil cylinder high pressure liquid oil just can get into fuel tank through liquid chunnel 8, realize release.
