Abstract
The utility model discloses a kind of screw-in cartridge valve, comprise valve pocket, spool, adjusting drive unit, O RunddichtringO group, described adjusting drive unit is positioned at described valve pocket, described O RunddichtringO group is between described valve pocket and described spool, and described O RunddichtringO group is made up of O RunddichtringO and back-up ring.The utility model is simple in structure, processing request is sealed and matched between good sealing effect, reduction valve piece and valve body.
Description
Technical field
The utility model relates to a kind of screw-in cartridge valve.
Background technique
Screw-in cartridge valve is taking liquid as medium, in hydraulic system, can be by motor-driven or electronic mode, and can regulate, control the oil circuit actions such as its flow direction, flow, pressure, its installation form is the hydraulic actuator that is threaded into formula.
Traditional screw-in cartridge valve sealing effect is bad, often in use can leak, very high to the processing request that is sealed and matched between valve piece and valve body.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides the screw-in cartridge valve of the processing request that is sealed and matched between a kind of simple in structure, good sealing effect, reduction valve piece and valve body.
The technical solution adopted in the utility model is: a kind of screw-in cartridge valve, comprise valve pocket, spool, adjusting drive unit, O RunddichtringO group, described adjusting drive unit is positioned at described valve pocket, described O RunddichtringO group is between described valve pocket and described spool, and described O RunddichtringO group is made up of O RunddichtringO and back-up ring.
Further, described back-up ring is one-sided back-up ring.
Further, described back-up ring is bilateral back-up ring.
Further, described back-up ring is nylon back-up ring.
Further, described spool is cone valve structure.
Further, described spool is back taper structure.
The screw-in cartridge valve that the utility model provides, simple in structure, good sealing effect, has reduced the processing request being sealed and matched between valve piece and valve body.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of screw-in cartridge valve, comprise valve pocket 1, spool 2, regulate drive unit 3, O RunddichtringO group 4, spool 2 is cone valve or pressure control valve structure, regulate drive unit 3 to be positioned at valve pocket 1, O RunddichtringO group 4 is between valve pocket 1 and spool 2, and O RunddichtringO group 4 is made up of O RunddichtringO 5 and back-up ring 6, and back-up ring 6 can be that one-sided nylon back-up ring can be also bilateral nylon back-up ring.
The utility model is owing to being provided with the O RunddichtringO group 4 being made up of O RunddichtringO 5 and back-up ring 6, thereby ensured zero leakage, and its good sealing effect, has reduced the processing request being sealed and matched between valve piece and valve body, and back-up ring 6 is except rising sealing; Also can prevent that O RunddichtringO 5 is squeezed in the gap of fitting surface under High Pressure, and make O RunddichtringO 5 uniform-compressions, not yielding impaired; Prevent that when mounted O RunddichtringO 5 is cut, play the effect of guiding loss prevention.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
