Abstract
The utility model provides a modified cold galvanizing bitangent cuts hydraulic system sealing device, connect including the fluid pressure line, valve platform box, O type sealing washer and pretension flange, the oil outlet and the fluid pressure line articulate of valve platform box, it realizes the sealed of fluid pressure line joint and valve platform box side to compress tightly O type sealing washer through the pretension flange, the fluid pressure line connects and the inside of valve platform box oil outlet link is fixed with the bush, bush one end is located the fluid pressure line and connects insidely, the oil outlet transition fit of one end and valve platform box, O type sealing washer suit is on the bush. The utility model discloses when the pretension flange radial displacement appears owing to bolt hole size grow, can effectively stop the radial displacement that the fluid pressure line connects and the O type encloses, promote the sealed effect of fluid pressure line joint and valve platform box by a wide margin, avoid the emergence of the oil leak condition, the assurance is normally produced, the bush can enclose support fixed action, further lift -off seal effect to the O type simultaneously, but the accurate positioning fluid pressure line connects during the installation, improves the installation effectiveness.
Description
Technical field
This utility model relates to the sealing device of a kind of improvement, particularly relates to the double clipping hydraulic system sealing device of cold galvanizing of a kind of improvement.
Background technology
The double clipping of smelter cold galvanizing line entrance is cut taking the lead the useless plate of magnetic tape trailer before welding for strip steel, drives double clipping strip to be cut off by HYDRAULIC CONTROL SYSTEM hydraulic cylinder., due to frequent movement, there is oil leakage of hydraulic system phenomenon often in double clippings, cause hydraulic system pressure to decline, and double clippings cannot normally work, and forces parking, have a strong impact on normal production.Fig. 1 is existing hydraulic system sealing device schematic diagram, hydraulic pipeline joint and hydraulic valve platform oil outlet connect, hydraulic pipeline joint and the sealing of valve platform body side is realized by pretension flange screw O RunddichtringO, through analyzing, the reason causing oil leakage phenomenon is: flange fixed bolt hole aperture after being dismounted for multiple times becomes larger, the mouth of pipe causing hydraulic pipeline joint loosens and radial displacement occurs, cannot seal in O is crushed on valve platform casing oil outlet after flange fastening, thus the oil leakage phenomenon of hydraulic pipeline joint and valve platform casing junction occurs.
Summary of the invention
Technical problem to be solved in the utility model is to provide the double clipping hydraulic system sealing device of cold galvanizing of a kind of improvement, the sealing effectiveness of hydraulic pipeline joint and valve platform casing can be substantially improved, it is ensured that double clippings normally work.
The technical scheme solving above-mentioned technical problem is:
The double clipping hydraulic system sealing device of the cold galvanizing of a kind of improvement, including hydraulic pipeline joint, valve platform casing, O RunddichtringO and pretension flange, the oil outlet of valve platform casing is connected with hydraulic pipeline joint, hydraulic pipeline joint and the sealing of valve platform body side is realized by pretension flange screw O RunddichtringO, its improvements are: the inside that described hydraulic pipeline joint is connected end with valve platform casing oil outlet is fixed with lining, lining one end is positioned at inside hydraulic pipeline joint, one end and the oil outlet interference fits of valve platform casing, O RunddichtringO is set on lining.
The double clipping hydraulic system sealing device of the cold galvanizing of above-mentioned a kind of improvement, described lining is one-body molded with hydraulic pipeline joint.
When this utility model is installed, first O RunddichtringO is set on lining, hydraulic pipeline joint is cased with in the oil outlet that valve platform casing is tapped down in one end of lining, hydraulic pipeline joint just can be made to be accurately positioned, limit the radial displacement of hydraulic pipeline joint, after pretension flange is fixed by screw, O RunddichtringO can be crushed to death on the side of valve platform casing, and sealing effectiveness is substantially improved.
The beneficial effects of the utility model are:
This utility model is positioned at valve platform casing oil outlet due to lining one end, O is set on lining, when there is radial displacement owing to bolt hole becomes large-sized in pretension flange, can effectively stop the radial displacement of hydraulic pipeline joint and O, the sealing effectiveness of hydraulic pipeline joint and valve platform casing is substantially improved, avoid the generation of leakage of oil situation, it is ensured that normally produce；O can be played support fixation, further lift-off seal effect by lining simultaneously；Installation effectiveness can be improved with fine positioning hydraulic pipe joint during installation.
Accompanying drawing explanation
Fig. 1 is existing hydraulic system sealing device schematic diagram；
Fig. 2 is this utility model schematic diagram；
Figure is labeled as: hydraulic pipeline joint 1, valve platform casing 2, oil outlet 3, O RunddichtringO 4, pretension flange 5, lining 6.
Detailed description of the invention
Fig. 2 shows, this utility model includes hydraulic pipeline joint 1, valve platform casing 2, O RunddichtringO 4 and pretension flange 5, valve platform casing oil outlet 3 is connected with hydraulic pipeline joint 1, compress O RunddichtringO 4 by pretension flange 5 and realize hydraulic pipeline joint 1 and the sealing of valve platform casing 2 side, the inside that hydraulic pipeline joint 1 is connected end with the oil outlet 3 of valve platform casing 2 is fixed with lining 6, lining 6 is one-body molded with hydraulic pipeline joint 1, one end of lining 6 is positioned at the inside of hydraulic pipeline joint 1, the other end is interference fits with the oil outlet 3 of valve platform casing 1, O RunddichtringO 4 is set on lining 6.
When this utility model is installed, first O RunddichtringO is set on lining 6, hydraulic pipeline joint is cased with in the oil outlet 3 that valve platform casing 1 is tapped down in one end of lining 6, hydraulic pipeline joint 1 just can be made to be accurately positioned, limit the radial displacement of hydraulic pipeline joint 1, after pretension flange 5 is fixed by screw, O RunddichtringO 4 can be crushed to death on the side of valve platform casing 2, and sealing effectiveness is substantially improved.
