The utility model discloses a plug-in hard-sealed bidirectional lock, comprising two sets of hydraulic components, wherein the inner cavity of the valve sleeve contains a valve core spring, one end of the valve core spring presses against the inner end of the valve sleeve, and the other end supports the valve core; the valve seat is threadedly connected to the valve sleeve, and the valve core forms a conical hard seal with the valve seat threadedly connected to the valve sleeve through the action of the valve core spring. The utility model adopts a plug-in hard-sealed structure, which has high system integration, high reliability, small size, long service life, and is easy to install and maintain. The bidirectional lock can be repaired directly by replacing the plug-in hydraulic components, which is simple, convenient and reliable.
Description
Technical field
The utility model relates to a kind of reversible lock, relates in particular to the plug-in hard sealing two-way lock of hydraulic support hydraulic circuit.
Background technology
Reversible lock plays important effect as the Hydraulic Elements of the two-way locking control of hydraulic cylinders such as colliery support compensating cylinder, wall supporting cylinder, and the reliability direct relation of reversible lock the security and stability of each parts of support.Along with the colliery instructions for use more and more develops with automation direction towards integrated; Reliability and application life require also increasingly high; Traditional reversible lock is owing to adopt the conical surface seal of valve pad sealing or polyformaldehyde material, and application life and accommodative ability of environment are not enough, and valve pad is easy to destroy under the extruding repeatedly of valve seat; The sealing of conical surface polyformaldehyde also can be caused seal failure by cinder or other hard thing destruction; The part kind of valve inner is many, repairs also very inconvenience, has more and more satisfied not the demand of colliery applying unit.In this case, we design, produce a kind of dependable performance through independent research, and compact conformation, adaptive capacity are strong, and installation, maintenance is reversible lock easily, satisfies user's use needs.
The utility model content
The purpose of the utility model provides a kind of plug-in hard sealing two-way lock, with reversible lock application life that solves prior art and the problem that adaptive capacity is low, integrated level is low and installation, maintenance is difficult.
In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of plug-in hard sealing two-way lock, comprise two cover hydraulic packages, and said valve pocket inner chamber contains valve core spring, and valve core spring one end withstands on valve pocket the inner, and the other end supports spool; Said valve seat and valve pocket are through being threaded; Spool seals through the valve core spring effect and the valve seat formation conical surface that is threaded on the valve pocket firmly; The valve seat end is provided with push rod spring; The push rod spring end is provided with push rod, and push rod is twisted through screw thread and closed the valve seat internal rows and become hydraulic package, and two cover hydraulic packages are placed in the valve body of multi-path and form plug-in hard sealing two-way lock.
The plug-in hard sealing structure is adopted in this practicality, and level of integrated system height, good reliability, little, the long service life of volume are easy to installation and maintenance, directly repairs this reversible lock through changing the plug-in hydraulic package, and is simple and convenient reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1.A kind of plug-in hard sealing two-way lock comprises two cover hydraulic packages, and said valve pocket 1 inner chamber contains valve core spring 2, and valve core spring 2 one ends withstand on valve pocket 1 the inner, and the other end supports spool 3; Said valve seat 4 and valve pocket 1 are through being threaded; Spool 3 seals through valve core spring 2 effects and the valve seat 4 formation conical surfaces that are threaded on the valve pocket 1 firmly; Valve seat 4 ends are provided with push rod spring 5; Push rod spring 5 ends are provided with push rod 6, and push rod 6 is twisted through screw thread and closed valve seat 4 internal rows and become hydraulic package, and two cover hydraulic packages are placed in the valve body 7 of multi-path and form plug-in hard sealing two-ways lock.
Two working chamber structures are identical; Its operating principle is following: the connected mode of this reversible lock is: the PA mouth connects reversal valve work sap cavity; The relative work sap cavity of reversal valve that the PB termination is corresponding with PA, the A mouth connects a chamber of wanting the locking oil cylinder, and the B mouth connects another chamber that needs locking of this oil cylinder.
When operating mode need be controlled A oil cylinder that mouth connects and stretches out; Reversal valve connects the work sap cavity of PA interface and opens feed flow; High-pressure work liquid gets into a PA mouth part and pushes spool 3 open, and working solution gets into the back and gets into the oil cylinder locked cavity through the A mouth, and the chamber action of this oil cylinder is stretched out; Another part high-pressure work liquid promotes the push rod 6 of another plug-in hydraulic package through valve body 7 inner hydraulic control working holes; The hydraulic package of opening opposite side was opened spool 3 and valve seat in 4 minutes, when that chamber work that connects the B mouth is shunk, and stable time liquid.When the PA end stopped feed flow, spool 3 formed the working solution locking that the metal hard-sealing collateral is held this oil cylinder working chamber with valve seat 4 under the pressure of valve core spring 2 that resets, and the initial sealing state that equally also returns to of the other end forms two-way locking steady working condition; When operating mode need be controlled B oil cylinder that mouth connects and stretches out, reversal valve connect the work sap cavity of PB interface and opens feed flow, formed and pairing action during PA confession liquid, finally realized two-way locking.
