Abstract

The utility model discloses a hydraulic control one-way valve which comprises a valve body (1), a valve core component (2), a control piston (3), a transmission piston (4), a plug (5) and a reset spring (6); the valve core component (2) is an overall assembly structure and is arranged in the valve body (1); and the reset spring (6), the control piston (3) and the transmission piston (4) are sequentially arranged in the other end of the valve body (1), and finally the plug (5) is screwed in. The hydraulic control one-way valve selects a direct-acting hydraulic control method, reduces a pilot-operated start part compared with a pilot-operated hydraulic control method, and has a simple and reliable structure; and simultaneously, the valve core component adopts an integral valve core and thus can be taken out together when in on-site repair, so that part loss is prevented and the re-installation also becomes simple and feasible.

Description

A kind of hydraulic control one-way valve

Technical field

The utility model belongs to the hydraulic pressure of the colliery control system, particularly a kind of hydraulic control one-way valve that is used for hydraulic support hydraulic control system.

Background technology

Hydraulic control one-way valve is one of most widely used Hydraulic Elements in the hydraulic support electricity hydraulic control system, is mainly used in the action control of all kinds of jack, can effectively prevent the misoperation of hydraulic support, ensures the production safety in colliery.

Generally adopt hydraulic control one-way valve in the hydraulic support hydraulic control system at present, can satisfy the basic need of Coal Production substantially.But these products adopt guide's open mode, and primary structure comprises guide's spool, guide's valve core reseting spring and guide district one way valve etc.Therefore the structure relative complex of existing one way valve not only increases product cost, has also increased the link that product breaks down.And the part many places of existing product are in scattered state, and each part all needs to pack into separately respectively valve body, in the down-hole maintenance, lose part easily when changing, reload also very difficult in the adverse circumstances of down-hole.

The utility model content

The purpose of this utility model is, overcomes the deficiencies in the prior art, and the hydraulic control one-way valve that a kind of structure is simple relatively, mechanical shock is little, easy to maintenance, be easy to change is provided.

Technical solution of the present utility model is: a kind of hydraulic control one-way valve comprises valve body, core assembly, control piston, drive piston, plug and return spring; Core assembly is an integral assembling structure, in the valve body of packing into; At the other end of valve body pack into successively return spring, control piston, drive piston, be screwed into plug at last.

Described core assembly comprises valve pocket, valve core spring, spool, attachment screw, joint ring and adapter sleeve; Valve core spring one end stretches in the valve pocket, and the other end contacts with spool; The other end of spool stretches in the adapter sleeve; Attachment screw connects into an integral body with valve pocket and adapter sleeve; Joint ring is positioned at the adapter sleeve outside, is used for the sealing between core assembly and the valve body.

The utility model beneficial effect compared with prior art is:

(1) structure is simple relatively.The utility model is selected Direct Action Type hydraulic control mode for use, than existing pilot-operated type hydraulic control mode structure decrease guide's opening section, simple and reliable for structure, reduce the link break down, reduce product cost.

(2) on-site maintenance and easy to maintenance.The utility model main working parts adopts the integral type spool, can take out together during field maintenance, avoids part to scatter and disappear, and reloads and also becomes simple.

(3) mechanical shock is little, and increase application life.The utility model adopts two drive pistons, utilizes airtight air space for buffering, reduces mechanical shock, increases product application life.

Description of drawings

Accompanying drawing 1 is the utility model hydraulic control one-way valve structural representation;

Accompanying drawing 2 is the structural representation of core assembly in the utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, be hydraulic control one-way valve of the present utility model, comprise valve body 1, core assembly 2, control piston 3, drive piston 4, plug 5 and return spring 6.Its assembly relation is: the core assembly 2 integral body valve body 1 of packing into, and fastening to be threaded; At valve body 1 other end pack into successively return spring 6, control piston 3, drive piston 4, be screwed into plug 5 at last, promptly finish the assembling of the utility model hydraulic control one-way valve.

Core assembly 2 is an integral assembling structure.In the present embodiment, the structure of core assembly 2 comprises valve pocket 21, valve core spring 22, spool 23, attachment screw 24, joint ring 25 and adapter sleeve 26 as shown in Figure 2; Valve core spring 22 1 ends stretch in the valve pocket 21, and the other end contacts with spool 23; The other end of spool 23 stretches in the adapter sleeve 26; Attachment screw 24 connects into an integral body with valve pocket 21 and adapter sleeve 26; Joint ring 25 is used for the sealing between core assembly 2 and the valve body 1 in adapter sleeve 26 outsides.

The operating principle of the utility model hydraulic control one-way valve is: as shown in Figure 1, valve body 1 is processed with A mouth, P mouth, each two place of Z mouth by spool position.Wherein one group P mouth connects high pressure fuel source, and the A mouth connects a chamber that needs reverse anchor in the jack, and the Z mouth connects the hydraulic control mouth; The A mouth of another group, P mouth, Z mouth are as pressure sensor or manometric interface, to monitor the force value of position everywhere.

When the needs medium when the P mouth flows to the A mouth, directly push spool 23 open and can realize; When the needs medium when the A mouth flows to the P mouth, core assembly 2 is in closed condition, must introduce hydraulic medium to the Z mouth, to promote drive piston 4 and control piston 3 to left movement, thereby the spool 23 in the promotion core assembly 2 is to left movement, and opening valve core assembly 2 is realized flowing of medium.

In the course of work of valve, the enclosure space that forms between drive piston 4 and the control piston 3 is compressed, and produces positice ground effect, the mechanical shock that can alleviate 3 pairs of core assemblies 2 of control piston.

The foregoing description is a kind of enumerating of the present utility model, and those skilled in the art can carry out various improvement and replacing not departing from according to different designing requirements and design parameters under the situation of the present utility model, fall into protection domain of the present utility model equally.

The unexposed part of the utility model manual is a techniques well known.
