Abstract
The utility model provides a two-way cartridge valve, and mainly solves the problem that a valve core of a conventional cartridge valve is easy to damage due to overlarge pressure compact. The two-way cartridge valve is characterized in that a V-shaped through groove is formed in one end, close to an oil port I, of the valve core. The two-way cartridge valve has the advantages that one V-shaped through groove is formed in one end, close to the oil port I, of the valve core, the oil circulation amount is gradually increased or decreased when an oil line system is switched on or switched off, so that the operation is stable, the stressed pressure compact is smaller, and stability and security of operation of the whole hydraulic system are not influenced due to the fact that compact to a hydraulic fluid when the valve core is switched on or switched off is reduced.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of two-way plug-in valve.
Background technique
Existing hydraulic cartridge valve, in the course of the work, spool will be subject to hydraulic shock, and excessive compression shock easily makes spool be damaged, thereby affects the use of cartridge valve.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of two-way plug-in valve, solves existing cartridge valve spool and is stressed and impacts excessive easily impaired problem.
The technological scheme that the utility model adopts: a kind of two-way plug-in valve, comprise valve pocket, spool, spring, valve pocket one end is axially arranged with hydraulic fluid port one, and the other end is established Packed end cap, and described valve pocket is radially provided with hydraulic fluid port two near hydraulic fluid port one one end;
Spool is arranged on valve pocket inside, coordinates with valve sleeving inner wall is smooth;
Described spool one end is provided with the counterbore of mounting spring, and the other end and hydraulic fluid port one are suitable, salable hydraulic fluid port one; Described spool is provided with a V-arrangement groove by one end of hydraulic fluid port one.
Described spool is step-like, and described spool is greater than the diameter by hydraulic fluid port one one end by the diameter of spring one end.
Described spool step is provided with the small-sized through hole of the counterbore that leads to spool.
The beneficial effects of the utility model are: adopt above scheme, described spool is provided with a V-arrangement groove by one end of hydraulic fluid port one, when oil-way system is opened or is closed, its logical oil mass is progressively to increase or reduce, so its stable working, suffered compression shock is less, thereby reduce to open or close because of spool, flow of pressurized is produced and impacts stability and the Security that affects whole hydraulic work system.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
1-valve pocket in figure, 2-spool, 3-spring, 4-end cap, 5-counterbore, 6-V shape groove, 7-step, 8-through hole, P1-hydraulic fluid port one, P2-hydraulic fluid port two.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of two-way plug-in valve, comprises valve pocket 1, spool 2, spring 3, and valve pocket 1 one end is axially arranged with hydraulic fluid port one P1, and the other end is established Packed end cap 4, and described valve pocket 1 is radially provided with hydraulic fluid port two P2 near hydraulic fluid port one P1 one end; Spool 2 is arranged on valve pocket 1 inside, coordinates with valve pocket 1 inner wall smooth, and described spool 2 one end are provided with the counterbore 5 of mounting spring 3, spring 3 one end are arranged in counterbore 5, the other end and end cap 4 offset, and the other end of spool 2 is suitable with hydraulic fluid port one P1, salable hydraulic fluid port one P1; Described spool 2 is provided with a V-arrangement groove 6 by one end of hydraulic fluid port one P1.
When being communicated with oil circuit, spool 2 impacts that be under pressure, just can move inward by Compress Spring 3, and the oil mass that circulates is to increase gradually until realize hydraulic fluid port one P1 and communicate completely with hydraulic fluid port two P2,
When closing oil circuit, spool 2 just can be replied under the reaction of spring 3, and circulation oil mass is to reduce gradually until realize hydraulic fluid port one P1 and hydraulic fluid port two P2 closure completely.
Owing to being progressively communicated with and closing, so its stable working, suffered compression shock is less, thereby reduces spool because being subject to impacting the damage bringing.
Described spool 2 is step-like, and described spool is greater than the diameter by hydraulic fluid port one P1 one end by the diameter of spring 3 one end, and under equal pilot pressure, thereby the less face area of diameter is less, and pressure is less, therefore can guarantee that control closes more reliable.
