Abstract
The invention relates to a hydraulic sealing part. The hydraulic sealing part comprises V-shaped rings and fixing rings and is characterized in that the fixing rings are fixedly connected onto shaft sleeves, ends of the fixing rings are abutted against pressure rings, ends of the pressure rings are abutted against the V-shaped rings, and ends of the V-shaped rings are abutted against supporting rings. The pressure rings and the supporting rings are fixedly connected onto a piston rod respectively, and the V-shape rings are closely contacted with the shaft sleeves and the piston rod. 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 cylinder sealing part. Further, the hydraulic cylinder sealing part is not only good in sealing performance under low pressure but also better in sealing performance as the contact area is widened along with increase of operation pressure.
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 V-type circle and retaining ring, it is characterized in that: described retaining ring is fixedly connected on axle sleeve, and the end of retaining ring is near pressure ring, and the end of pressure ring is near described V-type circle, and the end of V-type circle is near supporting ring.Described pressure ring and supporting ring are fixedly connected on respectively on piston rod, described V-type circle and axle sleeve and piston rod close contact.
Further technological scheme is:
Described V-type ring comprises multiple.
Described pressure ring has the recess matching with described V-type circle.
Described supporting ring has the protuberance matching with described V-type circle.
Technique effect of the present invention is:
The present invention is simple in structure, more traditional hydraulic seal, and it has good sealing effect, the advantage of convenient disassembly, the present invention not only has good sealability in the time of low pressure, and along with the raising of working pressure, area of contact increases, and sealability is better.
Brief description of the drawings:
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 multiple V-type circles 5 and retaining ring 2, retaining ring 2 is fixedly connected on axle sleeve 1, and the end of retaining ring 2 is near pressure ring 4, and the end of pressure ring 4 is near V-type circle 5, and the end of V-type circle 5 is near supporting ring 6.Pressure ring 4 and supporting ring 6 are fixedly connected on respectively on piston rod 3, V-type circle 5 and axle sleeve 1 and piston rod 3 close contacts.In the present invention, pressure ring 4 has the recess matching with V-type circle 5, and supporting ring 6 has the protuberance matching with V-type circle 5, and the effect of pressure ring 4 is to make V-type circle 6 form initial compression amount, and it is fully contacted with sealed.
V-type circle of the present invention has radial tightening while use, makes sealed close contact of its seal lip and internal-and external diameter, thereby in the time of low pressure, has good sealability, and along with the raising of working pressure, area of contact increases, and sealability is better.
