Abstract

The invention discloses a tubular connected high-flow hydraulic control one-way valve. The hydraulic control one-way valve comprises a plug-in hydraulic assembly and a tubular connected valve body with a compact structure; a swivel nut is in threaded connection with the interior of the valve body of the tubular structure; an ejection rod with hydraulic control effect is arranged in the swivel nut; a big spring is arranged at the front end of the ejection rod; the other end of the big spring is in contact with a liquid inlet sleeve; the swivel nut is connected with the liquid inlet sleeve through a rubber ring; the cavity of the front end of the liquid inlet sleeve is in contact with a big valve core to form metallic hard seal; and a small valve core is arranged in the big valve core and in contact with the big valve core to form metallic hard seal. The hydraulic control one-way valve is high in integration level, strong in reliability, long in service life and easy in installation and maintenance; and the upright post hydraulic control one-way valve is repaired directly, simply, conveniently and reliably by changing the plug-in hydraulic assembly.

Description

A kind of tubular type connects big flow hydraulic control one-way valve
Technical field
The present invention relates to a kind of hydraulic control one-way valve, in relating in particular to, the big flow column of the tubular type hydraulic control one-way valve in large hydraulic bracket hydraulic loop, high seam colliery.
Background technology
Since coal mine fully-mechanized mining begins, because the difference of various coal mining environment has had stricter requirement to hydraulic support and supporting equipment.The hydraulic support technology is got up towards high-end fast development, and support has been broken through 7 meters, and the column cylinder diameter also surpasses 0.5 meter, and so large-scale support presses for the hydraulic control one-way valve of the big dependable performance of flow and controls up-down.We are through independent development, have released that flow is big, long service life, column hydraulic control one-way valve easy to maintenance, and it has adopted valve rod integral type guide unloading way; The operating mode that can adapt to high pressure, big flow; Each sealing contact surface all adopts metal loop wire hard sealing structure simultaneously, and prolong application life greatly, and this cover core assembly is through the integrator that is threaded in addition; Realize the plug-in structure, keep in repair efficient and convenient.At present, domestic column control pilot operated valve device flow is little, during off-load hydraulic shock big, all can reduce each component and the bulk life time of valve; Sealing surface adopts material sealings such as valve pad or polyformaldehyde, has tiny cinder or other foreign matters on the coal mine work area unavoidably and gets in the hydraulic valve, when the pilot operated valve device opening and closing; Have impurity and be squeezed on the compressive seal, cause leakage, string liquid, adaptive capacity and application life are all not ideal enough; Traditional in addition valve group is combined by a lot of structural members; Change seal and will dismantle a lot of parts, the very inconvenience in the down-hole, a lot of problems are perplexing the operate as normal production of underground hydraulic support frame.
Summary of the invention
The purpose of this invention is to provide a kind of tubular type and connect big flow hydraulic control one-way valve,, application life high and adaptive capacity is low and the problem of maintenance difficult with the hydraulic shock of the column hydraulic control one-way valve that solves prior art.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of tubular type connects big flow hydraulic control one-way valve, and it comprises the line-mounted valve body of plug-in hydraulic package and compact conformation, and swivel nut is threaded in the valve body of tubular structure; A push rod that plays the hydraulic control effect is arranged in the swivel nut, and the push rod front end is provided with big spring, and the contact of the big spring other end puts at feed liquor; Be connected through rubber ring between swivel nut and the feed liquor cover; Feed liquor cover front end inner chamber contacts with big valve core and forms metal hard-sealing, and big valve core inside is provided with small valve core and contacts the formation metal hard-sealing with it, and the small valve core end is provided with spring; The spring top is provided with swivel nut, and swivel nut is integrated hydraulic package through being threaded in the valve body.
Level of integrated system height of the present invention, good reliability, long service life are easy to installation and maintenance, directly repair this column hydraulic control one-way valve through changing the plug-in hydraulic package, and be simple and convenient reliable.
Description of drawings
Fig. 1 is the main sectional view of reversal valve of the present invention.
The specific embodiment
Referring to Fig. 1, a kind of tubular type connects big flow hydraulic control one-way valve, and it comprises the line-mounted valve body 1 of plug-in hydraulic package and compact conformation; Swivel nut 2 is threaded in the valve body 1 of tubular structure; A push rod 3 that plays the hydraulic control effect is arranged in the swivel nut 2, and push rod 3 front ends are provided with big spring 4, and the contact of big spring 4 other ends is on feed liquor cover 5; Be connected through rubber ring 10 between swivel nut 2 and the feed liquor cover 5; Feed liquor overlaps 5 front end inner chambers and contacts the formation metal hard-sealing with big valve core 6, and big valve core 6 inside are provided with small valve core 7 and contact the formation metal hard-sealing with it, and small valve core 7 ends are provided with spring 8; The spring top is provided with swivel nut 2, and swivel nut 2 is integrated hydraulic package through being threaded in the valve body.
