Abstract
The invention relates to the technical field of control valves, and in particular relates to a guide oil source valve group. The guide oil source valve group is composed of a valve block body, a novel overflow valve, an accumulator and the like and is characterized in that the valve block body is formed by integrating the novel overflow valve, the accumulator, a filter and a command processor; after the novel overflow valve receives an instruction, the built-in command processor of the novel overflow valve operates valve core motion control software so as to realize a set function, thereby realizing a complicated system function; the accumulator absorbs pressure waves to provide stable pilot pressure, besides, the work of a liquid control valve can be still controlled by energy stored in the accumulator when equipment is powered off; and the valve body 23 of the novel overflow valve is respectively provided with four medium valve holes 22, the hole diameter of each valve hole 22 is large at the outside and small at the inside and is of a horn shape, and the inclined plane of the horn-shaped valve hole 22 and a valve body material surface are 80-degree file hole surfaces so as to more rapidly and accurately release the medium.
Description
Technical field
The present invention relates to the control valve technical field, especially a kind of guide's oil sources valve group.
Background technique
Need bigger power to promote when the hydraulic control valve of big flow is worked, if use solenoid controlled, then winding volume is very big, and power just can meet the demands, and the coil cost is very high like this, and the volume of control valve can be very big simultaneously, and cost performance is bad; If with manually control, cost has been a step-down, but manipulation strength is big, poor working environment the more important thing is and can not be realized telecontrol, inconvenient personnel operation.
Summary of the invention
The present invention provides a kind of simple in structure for the deficiency that overcomes prior art, little and the guide's oil sources valve group that can telecontrol of volume.
The present invention is made up of valve block, novel relief valve, accumulator etc., is characterised in that said valve block is integrated by novel relief valve, accumulator, filter and instruction processing unit.After novel relief valve received instruction, its embedded instruction processing unit just moved spool action control software and realizes the function of setting, thereby realizes complicated systemic-function.
Guide's hydrovalve block is joined accumulator, except the absorption pressure Reeb, provides outside the stabilizes forerunner pressure, and the another one major function is when device powers down, and the energy of accumulator storage can also continue to control the work of hydraulic control valve.
Novel relief valve; It is characterized in that; Comprise sealing 21, valve opening 22, valve body 23, valve pocket 24, nut 25, screw 26; Said novel relief valve; Be to be respectively equipped with 4 medium valve openings 22 on the valve body 23 as required; Imperial palace is horn-like for a short time outside valve opening 22 apertures, and the inclined-plane of its horn-like valve opening 22 and valve body material face are 80 degree angles files hole face, can be sooner dissolution medium more accurately.
Beneficial effect of the present invention: volume is little, and low price can be realized telecontrol and when a merit machine is out of service, guarantee hydrovalve work.

Embodiment
As shown in the figure; Guide's oil sources valve group is the chief component of guide's hydraulic system in the modern hydraulic machinery; Adopt with thread cartridge formula structure; It is little to have volume; Compact structure; Reduce pipe arrangement; Good seal performance; Advantages such as control range is big; Can adapt to heavy duty and bad working environments etc.; The design demand different according to the client; Guide's oil sources valve piece can have single solenoid valve; Dual-coil electromagnetic valve; Forms such as three solenoid valves; Also can increase accumulator and filter etc. as required; Its typical case is by designing 6 mouthfuls of 6 of cuttings or a plurality of runners, in order with control valve 1 with valve block 5; Accumulator 2; Filter 3; Relief valve 4 is installed respectively.Then, open the oil circuit mediation, accumulator 2 interfaces are got final product.Accumulator provides outside the stabilizes forerunner pressure except the absorption pressure Reeb, and the another one major function is when device powers down, and instruction processing unit 7 will can also continue to control the work of hydraulic control valve at the energy of accumulator 2 storages.Said novel relief valve is to be respectively equipped with 4 medium valve openings 22 on the valve body 23 as required, and imperial palace is horn-like for a short time outside valve opening 22 apertures, and the inclined-plane of its horn-like valve opening 22 and valve body material face are 80 degree angles files hole face, can be sooner dissolution medium more accurately.
Claims (2)
1. guide's oil sources valve group is made up of valve block, novel relief valve, accumulator etc., is characterised in that said valve block is integrated by novel relief valve, accumulator, filter and instruction processing unit.
2. like claim 1; The novel relief valve of said a kind of guide's oil sources valve group; It is characterized in that; Comprise sealing, valve opening, valve body, valve pocket, nut, screw; Said novel relief valve; Be to be respectively equipped with 4 medium valve openings on the valve body as required, imperial palace is horn-like for a short time outside the valve opening aperture, and the inclined-plane of its horn-like valve opening and valve body material face are file hole, 80 degree angles face.
