Abstract
A hydraulic control one way lock used for hydraulic support in coal mine comprises a valve body, a screwed gland, a valve element, and an adaptor assembly. The valve element is in a separable structure and includes a valve pocket assembly (a valve pocket, a control valve, a control spring and the like), a middle valve seat assembly, and a valve seat assembly (a valve seat, a piston assembly, a piston spring and the like). A chamber throughout the valve body is installed inside the valve body. The valve pocket in the valve element is mounted at the bottom of the chamber of the valve; the piston assembly and the piston spring are mounted in the chamber of the valve seat. The middle valve seat assembly is embedded into the valve seat, the valve pocket is embedded into the middle valve seat, and the control piston and the control spring are disposed in the valve pocket. The valve element is fixed by the screwed gland by a screw. The adaptor assembly is connected with the valve body. The pilot operated one way lock mainly improves the situation that the valve element could be jammed because of the coaxiality when the valve element is positioned into the valve body. The pilot operated one way lock is simple in structure and convenient to process, assemble and disassemble.
Description
Technical field
The utility model relates to coal mine underground hydraulic support frame, in particular for the fluid-control one-way lock of coal mine fully-mechanized mining working hydraulic support hydraulic control system.
Background technology
At present, in hydraulic support hydraulic control system, generally adopt fluid-control one-way lock, substantially can meet the needs of existing production, but the most structures of these products are comparatively complicated, processing technology is had relatively high expectations, and it is more difficult to make to install and keep in repair, and has had a strong impact on quality and the whole service life of product
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and is convenient to installation and maintenance, and overall performance is good and lock for the fluid-control one-way on hydraulic support.
To achieve these goals, the solution that the utility model is taked is: a kind of lock of the fluid-control one-way for coal mine hydraulic supporting, comprises valve body, screw thread gland, spool and adapter assembly; Wherein spool is split-type structural, comprises valve pocket assembly (valve pocket, control piston, control spring etc.), middle valve component, valve component (valve seat, piston component and piston spring etc.); In valve body, be provided with the cavity that runs through valve body.Valve seat in described spool is arranged on valve body cavity bottom, and piston component and piston spring are placed in valve seat cavity; In described middle valve component inserted valve seat, during described valve pocket embeds, in valve seat, control piston and control spring are arranged in valve pocket; Described screw thread gland is fixed spool by screw thread; Described adapter assembly is connected on valve body.
The cavity of described valve body only has three stepped holes, and spool cavity is a straight hole.
Described spool is split type pattern: valve pocket assembly, middle valve component, valve component.
The utility model has the advantage of simple in structure the cavity of described valve body, reduced greatly difficulty of processing, guarantee constant product quality; Cavity is the cavity that runs through valve body, greatly facilitates the detachable maintaining of fluid-control one-way lock; Meanwhile, valve core structure is split type pattern, reduces axiality requirement is installed, and improves product quality stability, and the performance of product entirety is improved.
Accompanying drawing explanation
The specific embodiment
As shown in the figure, fluid-control one-way lock described in the utility model, comprises valve body (1), screw thread gland (2), spool (3) and adapter assembly (4); Core assembly comprises control piston (8), control spring (9), valve pocket (10), middle valve component (11), piston component (12), piston spring (13) and valve seat (14); It is characterized in that: the valve body (1) that contains cavity, the valve seat (14) that is arranged on valve body (1) cavity bottom, in valve seat (14), place piston component (12) and piston spring (13); Middle valve component (11) is connected with valve seat (14); Valve pocket (10) is connected with middle valve component (11), control piston (8) and control spring (9) are placed in valve pocket (10), by screw thread gland (2), spool (3) are fixed.Adapter assembly (4) is communicated with the cavity of valve body (1), and the control liquid import (7), inlet (6), the liquid outlet (5) that are opened on valve body (1) communicate with valve body (1) cavity respective cavities respectively.Valve body cavity is simple in structure, easy to process; Spool is split type pattern, easy for installation, and axiality is good, thereby has greatly improved product quality, and good stability, increases the service life.
