Abstract
The utility model relates to a hydraulic flange sealing device, which comprises a flange, a connecting pipe, an oil pipeline and a seal ring. The flange and the oil pipeline are connected through occlusal bolts, the connecting pipe and the oil pipeline are fixed together through the flange, the front end of the connecting pipe extends into the oil pipeline, the surface of the front end of the connecting pipe is provided with a circular groove, the seal ring is mounted in the circular groove, and a gap between the connecting pipe and the inner wall of the oil pipeline is sealed through the seal ring. The hydraulic flange sealing device is reasonable in structural design and fine in sealing effect, and oil leakage is avoided effectively and equipment accident rate is reduced with the hydraulic flange sealing device.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly relates to a kind of hydraulic pressure flange sealer.
Background technique
The oil pipe flange seal of hydraulic system often adopts the structural type of seal ring or combination mat, at the scene in the using process, because the work on the spot environment is abominable, the equipment vibrations are big, work causes the handle of flange to close bolt looseness for a long time, high-pressure and hydraulic oil leaks from flange facing, thereby produces equipment accident, has brought great potential safety hazard to ordinary production.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, the hydraulic pressure flange sealer of good sealing effect.
In order to address the above problem, the utility model by the following technical solutions:
The hydraulic pressure flange sealer, comprise flange, connecting tube, oil pipe pipeline and seal ring, flange closes bolt with the oil pipe pipeline by handle and is connected, connecting tube is fixed together by flange and oil pipe pipeline, the connecting tube front end stretches into oil pipe pipeline inboard, the connecting tube front end surface is provided with circular groove, and seal ring is installed in the circular groove, seals by seal ring between connecting tube and the oil pipe pipeline inner wall.
Compared with prior art, the beneficial effects of the utility model are:
The utility model changes seal form between connecting tube and the oil pipe pipeline inner wall sealing by the sealing between two original flanges, even take place close bolt loosening individually, fluid can not revealed yet, and has effectively reduced accident rate, has guaranteed the stable smooth operation of producing.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the schematic diagram of sealing device before improving.
Embodiment
Hydraulic pressure flange sealer before improving as shown in Figure 2, seal ring 4 is installed in the groove of connecting tube 1 end face, pass through seal ring 4 crush seals between connecting tube 1 end face and oil pipe pipeline 5 end faces, if closing bolt 3 loosening phenomenon takes place, the slit will appear between connecting tube 1 and the oil pipe pipeline 5, thereby the phenomenon of leakage of oil takes place, cause the generation of equipment accident.
The utility model improves existing equipment, as shown in Figure 1, comprise flange 2, connecting tube 1, oil pipe pipeline 5 and seal ring 4, flange 2 closes bolt 3 with oil pipe pipeline 5 by handle and is connected, connecting tube 1 is fixed together by flange 2 and oil pipe pipeline 5, and connecting tube 1 front end stretches into oil pipe pipeline 5 inboards, and connecting tube 1 front end surface is provided with circular groove, seal ring 4 is installed in the circular groove, seals by seal ring 4 between connecting tube 1 and oil pipe pipeline 5 inwalls.By seal ring 4 crush seals, even take place close bolt 3 looseningly, fluid can not revealed yet, thereby has avoided the generation of oil accident between connecting tube 1 and the relevant pipeline.
Claims (1)
1. hydraulic pressure flange sealer, comprise flange, connecting tube, oil pipe pipeline and seal ring, flange closes bolt with the oil pipe pipeline by handle and is connected, connecting tube is fixed together by flange and oil pipe pipeline, it is characterized in that the connecting tube front end stretches into oil pipe pipeline inboard, the connecting tube front end surface is provided with circular groove, seal ring is installed in the circular groove, seals by seal ring between connecting tube and the oil pipe pipeline inner wall.
