Abstract
The utility model discloses a cartridge valve comprising a control cover assembly, a sealing ring, a valve pocket, a valve core and a valve body, which is mainly characterized in that the sealing ring is moved to be installed from the convexity of the lower end of the control cover assembly to the top of the valve pocket. The convexity is modified to be a flat surface, so that the lower end face of the control cover is convenient in processing. Meanwhile, the guide distance of the valve core is increased, so that the guide performance of the valve core and the control stability are improved.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of cartridge valve.
Background technique
Valve is used for control oil channel and switches as a control unit of hydraulic system, and kind is a lot, cartridge valve is wherein a kind of, and it is to adopt guide's control, the novel hydraulic control unit that the bottom valve structure is connected with plug-in type, can realize not having the control of leakage, long service life.But its seal ring of existing cartridge valve generally all is contained on the projection on the control cover plate assembly lower end surface, is connected with the contact of valve pocket top, and doing one like this is that the projection of control cover plate assembly lower end is processed cumbersome; The 2nd, spool stroke is short, stability property.For this makes improvements the steering capability of design with the raising spool to its structure, and then improve the control stability of cartridge valve.
The model utility content
The purpose of this utility model is that a kind of novel cartridge valve that can effectively solve the existing existing poor stability of cartridge valve will be provided.
The utility model is achieved in that cartridge valve comprises control cover plate assembly, seal ring, valve pocket, spool and valve body, wherein the control cover plate assembly is connected by screw with valve body, valve pocket is inserted in the valve body, spool is contained in the valve pocket, and ring set (directly contacts with plane, control cover plate assembly lower end) on the valve pocket top.All the other structures and component and existing product are same or similar.
The novel cartridge valve that designs and produces according to technique scheme is compared its main feature and is with existing product: make the projection of dress seal ring on the control cover plate assembly lower end surface into plane, and seal ring is retrofitted in the top of valve pocket, the length of valve pocket has extended like this, the corresponding also lengthening of the length of spool, this helps improving steering capability, improves stability.Moreover processing and fabricating is also more convenient after making convex portion into plane on the lower end surface of control cover plate assembly.
Description of drawings
The structural representation of Fig. 1, existing cartridge valve;
The structural representation of Fig. 2, the utility model cartridge valve.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further narration.
Cartridge valve of the present utility model comprises as shown in Figure 2: control cover plate assembly 1, seal ring 2, valve pocket 3, spool 4 and valve body 5, wherein be connected by screw between control cover plate assembly 1 and the valve body 5, valve pocket 3 is inserted in the valve body, and spool 4 is contained in 3 li of valve pockets, and seal ring 2 is sleeved on the top of valve pocket 3.All the other structures and component and existing product are same or similar, and its working principle is also identical with existing product.
