Abstract
The invention relates to a hydraulic sealing part. The hydraulic sealing part comprises an O-shaped ring and a slide ring and is characterized in that the O-shaped ring is positioned in an annular groove of a piston rod, and the slide ring is positioned between the O-shaped ring and the inner wall of a cylinder body and closely contacts with the inner wall of the cylinder body and the O-shaped ring. The hydraulic sealing part is simple in structure and has the advantages of effectiveness in sealing and convenience in demounting as compared with a traditional hydraulic sealing part. Due to the fact that the slide ring and the inner wall of the cylinder body are in line contact, frictional force is greatly reduced, and the service life of the hydraulic sealing part is prolonged.
Description
Technical field:
The present invention relates to hydraulic equipment field, particularly hydraulic seal.
Background technique:
Sealing is to solve one of effective means of hydraulic system leakage problem.In the time that the sealing of hydraulic system is bad, can be because of external leakage befouling environment; Also can cause air to enter hydraulic system and affect the service behaviour of oil hydraulic pump and the stationarity of hydraulic actuator motion; In the time that internal leakage is serious, can cause the too low and oil liquid temperature of system volume efficiency to rise too high, so that system cisco unity malfunction.Along with the progress of technology and the raising of equipment performance, hydraulic system is more and more higher to the requirement of sealing, and the independent use of traditional seal ring can not well be satisfied the demand.
Summary of the invention:
The applicant, for the above-mentioned shortcoming of conventional hydraulic Sealing, studies and improves, and a kind of hydraulic seal is provided, and it has the feature of simple in structure, convenient disassembly, good sealing effect.
In order to address the above problem, the present invention adopts following scheme:
A kind of hydraulic seal, comprises O type circle and slip ring, it is characterized in that: described O type circle is positioned at the annular groove of piston rod, and described slip ring is positioned between O type circle and inboard wall of cylinder block, and with described inboard wall of cylinder block and described O type circle close contact.
Further technological scheme is:
The cross section inner ring of described slip ring has cone angle.
Technique effect of the present invention is:
The present invention is simple in structure, more traditional hydraulic seal, and it has good sealing effect, and the advantage of convenient disassembly contacts because slip ring and inboard wall of cylinder block adopt line, greatly reduces frictional force, has extended working life.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
See Fig. 1, the present invention includes O type circle 2 and slip ring 3, it is characterized in that: described O type circle 2 is positioned at the annular groove 5 of piston rod 1, described slip ring 3 is positioned between O type circle 2 and cylinder body 6 inwalls, and with described cylinder body 6 inwalls and described O type circle 2 close contacts.The cross section inner ring of described slip ring 3 has cone angle 4, makes slip ring 3 and cylinder body 6 inwalls form line contact form.
The present invention has given full play to the strong point separately of RUBBER O RunddichtringO and slip ring, not only reliable operation, and frictional force is low and stable type good, has greatly extended working life.
Claims (2)
1. a hydraulic seal, comprises O type circle and slip ring, it is characterized in that: described O type circle is positioned at the annular groove of piston rod, and described slip ring is positioned between O type circle and inboard wall of cylinder block, and with described inboard wall of cylinder block and described O type circle close contact.
2. according to hydraulic seal claimed in claim 1, it is characterized in that: the cross section inner ring of described slip ring has cone angle.
