Abstract
The utility model discloses a hard-sealing hydraulic control valve core inserting piece, comprising a liquid feeding valve sleeve, a spring, a valve core and a liquid returning valve sleeve, wherein the liquid feeding valve sleeve is internally provided with the spring and the spring is internally sleeved with the valve core; an annular line sealing structure is formed by the valve core and a valve seat; the liquid returning valve sleeve is internally provided a piston and is connected with the liquid feeding valve sleeve through a thread to form a whole body. The hard-sealing hydraulic control valve core inserting piece disclosed by the utility model has the advantages of conveniently-detached structure, strong reliability and long service life, and greatly prolongs the whole service life of a hydraulic valve.
Description
Technical field
The utility model relates to a kind of hydraulic control spool plug-in unit, a kind of specifically hard sealing hydraulic control spool plug-in unit
Background technology
Traditional hydraulic support valve class is the pilot operated valve device core assembly of reversal valve main valve class the inside especially; Complex structure, the dismounting difficulty, hermetically-sealed construction adopts metal spool and coal to grind No. three valve pad vertical compression sealings more; Perhaps the valve seat of metal spool and polyformaldehyde material forms conical surface linear sealing; Mostly seal form is soft seal, and application life and reliability are very low, has influenced carrying out smoothly of coal mine fully-mechanized mining work greatly.Prosperous company produces a kind of novel hard sealing hydraulic control spool plug-in unit through the independent research design, has improved the performance and the life-span of this type hydraulic control greatly.
The utility model content
The purpose of the utility model provides a kind of novel hard sealing hydraulic control spool plug-in unit, to solve the problem that some hydraulic control spool dismounting are complicated, sealing reliability is poor, application life is low of prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of hard sealing hydraulic control spool plug-in unit includes feed liquor valve pocket, spring, spool, feed liquor valve pocket, and said feed liquor valve pocket inside is provided with spring, is sheathed with spool in the spring, and spool and valve seat form the loop line hermetically-sealed construction; Said liquid return valve jacket inner chamber is provided with piston, and liquid return valve jacket and feed liquor valve pocket are through the integrator that is threaded.
The utility model structure easy accessibility, good reliability, high life has improved the whole service life of hydraulic valve greatly.
Description of drawings
Fig. 1 is the utility model knot sketch map.
