Abstract
The invention discloses a threaded inserting valve. The threaded inserting valve comprises a valve sleeve, a valve core, an adjusting driving device and an O-shaped sealing ring set; the adjusting driving device is positioned into the valve set; the O-shaped sealing ring set consisting of an O-shaped sealing ring and a baffling ring is positioned between the valve sleeve and the valve core. The threaded inserting valve is simple in structure, has a good sealing effect, reduces the sealing fit between a valve block and a valve body, and meets the processing requirements.
Description
Technical field
The present invention relates to a kind of screw-in cartridge valve.
Background technique
Screw-in cartridge valve is to take liquid as medium, in hydraulic system, can regulate, control the oil circuit actions such as its flow direction, flow, pressure by motor-driven or electronic mode, and 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.
Summary of the invention
In order to solve the problems of the technologies described above, the invention 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 used in the present invention 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 comprised 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.
Screw-in cartridge valve provided by the invention, simple in structure, good sealing effect, has reduced the processing request being sealed and matched between valve piece and valve body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention 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 comprised 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 present invention is owing to being provided with the O RunddichtringO group 4 being comprised of O RunddichtringO 5 and back-up ring 6, thereby guaranteed 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 and 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 the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
