Abstract
The utility model relates to a quick self-sealing valve for a hydraulic pipeline. The quick self-sealing valve comprises a female joint and a male joint, and is characterized in that a valve core component and a valve bush of the female joint realize self-sealing; a guide sleeve, a pipe sleeve and an outer sleeve are arranged outside the valve bush; the pipe sleeve is provided with a locking steel ball; the guide sleeve and the outer sleeve can more transversely; a spring is arranged in front of the guide sleeve and the outer sleeve; a valve of the male joint can realize self-sealing with a sealing element under action of an offsetting spring; and a steel ball groove is formed on the shell outside the valve. The quick self-sealing valve has the beneficial effects that the self-sealing joint is convenient and simple to operate when used; only one motion can realize joint and detachment of the female joint and the male joint; and the detachment is quick, and no residual oil appears, so that the environment pollution is not caused, and the oil liquid cannot be lost in the system.
Description
Technical field
The utility model belongs to the control technique of the quick break-make of hydraulic pipe line, relates to a kind of improvement of self-sealing joint structure.
Background technique
Be used for quick self-sealing joint structures that adopt push rod to open valve when butt joint of liquid medium more at present, receive its structural reason, there is serious excess oil phenomenon in it in separation process, not only cause the loss of fluid, also pollutes Environmental Conditions.
Summary of the invention
The purpose of the utility model isProvide a kind of simple to operate, can be implemented in the Fast Dual self-sealing joint that does not have dielectric leakage in the separation process, to solve the shortcoming of present self-sealing joint.
The technological scheme of the utility model is:A kind of quick self-styled valve that is used for hydraulic pipe line comprises negative joint and male connector, it is characterized in that: the mangetic core assembly of negative joint and valve pocket are realized selfsealings; Guide pin bushing is arranged outside valve pocket, and pipe box and overcoat have place kick on the pipe box; Guide pin bushing and overcoat ability move left and right have spring before guide pin bushing and the overcoat; The valve of male connector is realized selfsealings with Sealing under the effect of Returnning spring, on the housing outside the valve ball groove is arranged.
Optimize: the exterior edge face of mangetic core assembly and valve is the plane.
The beneficial effect of the utility model is:Easy and simple to handle when the utility model self-sealing joint uses, only need butt joint that an action just can realize male and female connector and separate, and separate rapidly, no excess oil appearance can not cause the pollution of Environmental Conditions, fluid that yet can loss system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Explain further details in the face of the utility model down.
When separated state, each selfsealing of negative joint and male connector.The mangetic core assembly 1 of negative joint forms a selfsealings pair with valve pocket 2, guarantees the selfsealings property of negative joint; Male connector promotes valve 10 and contacts formation selfsealings pair with Sealing 7 under the effect of Returnning spring 11, guarantee the selfsealings property of male connector.
In docking operation, at first the end face of the valve 12 of the end face of the mangetic core assembly 1 of negative joint and male connector contacts, and makes housing 11 promotion guide pin bushings 4 oppress spring 3 again and moves backward.With before valve pocket 2 end faces contact, valve pocket 2 keeps constant relatively (promptly being in sealing state) with the position of spool 1 at guide pin bushing 4 end faces.When guide pin bushing 3 end faces contact with the ladder surface left side of valve pocket 2 end faces; Valve pocket 2 is also moved backward; This just makes the negative joint valve open gradually, and the outside seal that forms when dock of valve pocket 2 and Sealing 10 is secondary before this, the outside seal property in the assurance docking operation.So just make male and female connector form passage (this moment, Returnning spring was in oppressed state), when the steel ball groove A of housing 11 arrived the steel ball position of pipe box 5, steel ball 8 fell into the steel ball groove; Overcoat 6 loses places restrictions on (before this, axially the place restrictions on effect of the inclined-plane of 8 pairs of overcoats of steel ball to the right), and joint motion faces south under the effect of spring 7; Steel ball can not be resetted and be locked; When it moved to the position of back-up ring 9, the two-part relative movement of male and female connector stopped, and docking operation is accomplished.
In separation process, only need pulling overcoat 6, steel ball is removed placed restrictions on, this moment, male connector was unlocked, and male connector is ejected and is realized selfsealings automatically under the effect of spring 13, and valve pocket 2 automatically resets under the effect of spring and hydraulic coupling simultaneously, makes negative joint self-styled.Mangetic core assembly 1 is in fit-state all the time with valve 12 in separating process, and the inwall of both and housing 11 fits fluid free residual space.
Claims (2)
1. a quick self-styled valve that is used for hydraulic pipe line comprises negative joint and male connector, it is characterized in that: the mangetic core assembly of negative joint and valve pocket are realized selfsealings; Guide pin bushing is arranged outside valve pocket, and pipe box and overcoat have place kick on the pipe box; Guide pin bushing and overcoat ability move left and right have spring before guide pin bushing and the overcoat; The valve of male connector is realized selfsealings with Sealing under the effect of Returnning spring, on the housing outside the valve steel ball groove is arranged.
2. a kind of quick self-styled valve that is used for hydraulic pipe line according to claim 1 comprises negative joint and male connector, and it is characterized in that: the exterior edge face of mangetic core assembly and valve is the plane.
