Technical field
The utility model relates to sealing device technical field more particularly to a kind of v-seal devices.
Background technique
In hydraulic system and its system, sealing device is used to prevent leakage and extraneous dust and the foreign matter of working media
Intrusion, leakage will cause the waste of working media, pollute machine and environment, or even cause mechanically actuated failure and equipment person thing
Therefore interior leakage can cause hydraulic system volumetric efficiency sharply to decline, and required operating pressure be not achieved, or even not can be carried out work
Make, the minute dust particle in invasive system, can cause or aggravate the secondary abrasion of Hydraulic Elements friction, further result in leakage,
Therefore, sealing element and sealing device are an important components of hydraulic device.The reliability and service life of its work,
It is an important indicator for measuring hydraulic system quality, the sealing between general oil cylinder and piston is all to make phase using sealing element
Gap control between adjacent two couplings surface is below the minimum clearance for needing the liquid sealed that can pass through.Sealing element generally comprises
Sealing ring, support ring and support base, but defective tightness is connected between traditional sealing element, cause device not convenient enough when installing.
Summary of the invention
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of v-seal dress proposed
It sets.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of v-seal device, including support ring and support base, one end of the support base open up it is fluted, in groove
It is placed with V-shaped ring, the other end of V-shaped ring is in contact with support ring, and is fixedly connected with that there are two horizontal on support base
The fixed link of setting, fixed link offer mounting groove far from one end of support ring, telescopic rod, telescopic rod are inserted with inside mounting groove
The fixture block of circular ring shape is provided with close to one end of fixed link, and telescopic rod is connected far from one end of support base with support ring, branch
It is opened up on pushing out ring there are two horizontally disposed screw hole, telescopic rod is threadedly coupled with support ring.
Preferably, two through-holes are opened up on the V-shaped ring, and the aperture of through-hole is greater than the outer diameter of fixed link.
Preferably, the telescopic rod is equipped with "-" type or criss-cross groove far from one end of fixed link.
Preferably, the inner wall gluing of the mounting groove is connected to spring, and spring is socketed in the outside of telescopic rod, and spring
Between fixture block and the inner wall of mounting groove.
The beneficial effects of the utility model are: this sealing device is in use, select suitable V according to the length of sealing area
The number of V-shaped ring, V-shaped ring is socketed in fixed link, then is clamped V-shaped ring by support ring and support base,
Finally finally make support ring and support base by V-arrangement so that telescopic rod is closely connect with screw hole using screwdriver rotation telescopic rod
Sealing ring clamps, and V-shaped ring is laterally sufficiently clamped at this time, and V-shaped ring can be improved longitudinal sealing performance, and fill
It sets in an entirety, facilitates installation.
