Abstract
The utility model discloses a cartridge valve which comprises a control valve, a valve plug and a valve block body and is characterized in that the control valve is wholly arranged on an integrated valve body formed by the valve block body and a valve bush by a control cover plate, the valve body is internally provided with the valve plug internally provided with a spring, and at the moment, the upper end and the lower end of the spring are connected with the control cover plate and the bottom of the valve plug; furthermore, the valve is provided with two working ports A and B. The cartridge valve can ensure large through-current capability and good sealing performance, not only can solve the problem of sealing performance well, but also has the characteristic of simple structure, thus being applicable to larger systems with higher flow rate or systems with higher sealing performance requirements.
Description
Technical field
The utility model relates to a kind of valve, specifically a kind of cartridge valve that is used for hydraulic pressure.
Background technique
Be all can use valve somewhere at present, yet all be to adopt floating ball and fixing spherical structure mostly, rely on the elastic element at valve left and right sides valve body or valve seat back that sealing force is provided, solve the sealing problem of valve, this structure just fits together from the assembling beginning tightly because of ball seal face and sealing surface of seat, in use, valve of every keying, all can cause certain wearing and tearing to ball seal face and valve seat, and, open and close very effort, like this because of frictional force is big, the sealing surface life-span of valve is very short, causes a large amount of wastes of resource.And a lot of valves all exist the shortcoming of poor sealing performance, thus need to improve, so the utility model this provide a kind of through-current capability greatly, the cartridge valve of good seal performance, overcome more above-described defective.
The model utility content
The purpose of this utility model is to provide a kind of through-current capability big, and the cartridge valve of good seal performance not only can solve the problem of sealability well, also has characteristic of simple structure, the system that is useful for the big system of flow or sealability is had relatively high expectations.
The technical solution of the utility model is achieved in that a kind of cartridge valve, comprise control valve, spool, valve block, it is characterized in that: control valve is being constituted by valve block and valve pocket on the valve body of one by the control cover plate integral installation, and be provided with spool at valve inner, spring is housed again in the spool, and this moment, the spring upper and lower end connected the bottom of control cover plate and spool; And valve body is provided with two actuator ports of A, B.
Advantage of the present utility model is: 1. through-current capability is big, good seal performance; 2. be active in one's movements, simple in structure, thereby the system that is mainly used in the big system of flow or sealability is had relatively high expectations.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: the 1-control valve; The 2-control cover plate; The 3-spool;
The 4-valve block; The 5-valve pocket; The 6-spring.
Embodiment
Below in conjunction with accompanying drawing the utility model is explained:
As shown in Figure 1, a kind of cartridge valve, comprise control valve 1, spool 3, valve block 4, control valve 1 is being constituted on the valve body of one by valve block 4 and valve pocket 5 by control cover plate 2 integral installations, and be provided with spool 3 at valve inner, spring 6 is housed again in the spool 3, and this moment, spring 6 upper and lower end connected the bottom of control cover plate 1 and spool 3; And valve body is provided with two actuator ports of A, B.
A and B are only two actuator ports of working connection among the figure, and K is control port (joining with pilot valve).When the K mouth did not have the hydraulic coupling effect, the hydraulic coupling that makes progress that spool is subjected to was greater than spring force, and spool is opened, and A communicates with B, as for the direction of liquid stream, decided on the pressure size of A, B mouth.Otherwise when the K mouth has action of hydraulic force, and the oil liquid pressure of K mouth could guarantee to close between A and the B greater than the oil liquid pressure of A and B mouth.Cartridge valve and the combination of various pilot valve just can be formed position control valve, pressure controlled valve and flow control valve.Its feature is that through-current capability is big, and good seal performance is active in one's movements, simple in structure, thereby the system that is mainly used in the big system of flow or sealability is had relatively high expectations.
