Abstract
The utility model provides a kind of for small pressure container vacuum-pumping density sealing joint match equipment, comprises shroud, described shroud is fixedly installed and vacuumizes connection mouth; The inner arm of described shroud sets gradually some the first seal grooves, each described seal groove is all fixedly installed the first seal ring; Wherein said shroud internal fixtion slides and is provided with shrouding, and a pull bar passes described shroud aperture and is connected and fixed with one end of described shrouding; The external cylindrical surface of described shrouding is provided with the second seal groove and arranges the second seal ring in described second seal groove; The beneficial effects of the utility model: the storage tank being applicable to below 20m3, the sealability of sealed joint apparatus when ensureing that pressurized container vacuumizes, increases sealing contact surface, thus reaches the effect improving and vacuumize efficiency.
Description
Technical field
The utility model relates to a kind of vacuum sealing joint match equipment of the storage tank for below 20m3; Particularly relate to a kind of for small pressure container vacuum-pumping density sealing joint match equipment.
Background technique
Pressurized container is applied in each manufacture field, to carry out vacuumizing process when making pressurized container, just in case deal with the Security that will affect pressurized container improperly, think sealability when guaranteeing that pressurized container vacuumizes, when vacuumizing, the design of SEALING FITTING match equipment is even more important, the match equipment design of current use is unreasonable, poor sealing performance.
Model utility content
The utility model provides a kind of for small pressure container vacuum-pumping density sealing joint match equipment, reasonable in design, make simple, easy to operate, be applicable to the storage tank of below 20m3, the sealability of sealed joint apparatus when ensureing that pressurized container vacuumizes, increases sealing contact surface, thus reaches the effect improving and vacuumize efficiency.
The utility model is achieved through the following technical solutions: a kind of for small pressure container vacuum-pumping density sealing joint match equipment, comprises shroud, described shroud is fixedly installed and vacuumizes connection mouth; The inner arm of described shroud sets gradually some the first seal grooves, each described seal groove is all fixedly installed the first seal ring; Wherein said shroud internal fixtion slides and is provided with shrouding, and a pull bar passes described shroud aperture and is connected and fixed with one end of described shrouding; The external cylindrical surface of described shrouding is provided with the second seal groove and arranges the second seal ring in described second seal groove.
Be as further improvement of the utility model: the aperture place that described pull bar penetrates shroud arranges the 3rd seal ring.
Be as further improvement of the utility model: described first seal ring, the second seal ring and the 3rd seal ring are O type circle.
Because in the utility model, the inwall of shroud is provided with the first seal groove, can with the external cylindrical surface fitted seal of SEALING FITTING, in time closing shrouding, can from the air vacuumized in connection mouth extraction shroud, in time pulling pull bar, vacuum pumping device gets final product the air in evacuation container chuck, reaches the effect of duplicate protection sealing; And first seal ring can ensure the sealability in space in shroud; Sealability when second seal ring guarantee shrouding contacts with SEALING FITTING; When 3rd seal ring ensures that pull bar pulls up and down, the sealability of pull bar and shroud.
The beneficial effects of the utility model: the storage tank being applicable to below 20m3, the sealability of sealed joint apparatus when ensureing that pressurized container vacuumizes, increases sealing contact surface, thus reaches the effect improving and vacuumize efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan view of the present utility model;
Wherein 1-shroud, 2-vacuumize connection mouth, 3-the 3rd seal ring, 4-first seal groove, 5-first seal ring, 6-shrouding, 7-pull bar, 8-second seal groove, 9-second seal ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, 2: the one of the present embodiment is used for small pressure container vacuum-pumping density sealing joint match equipment, comprises shroud 1, described shroud 1 is fixedly installed and vacuumizes connection mouth 2; The inner arm of described shroud 1 sets gradually two the first seal grooves 4, each described seal groove 4 is all fixedly installed the first seal ring 5; Wherein said shroud 1 internal fixtion slides and is provided with shrouding 6, and a pull bar 7 passes the aperture of described shroud 1 and is connected and fixed with one end of described shrouding 6; The external cylindrical surface of described shrouding 6 is provided with the second seal groove 8 and arranges the second seal ring 9 in described second seal groove 8.
The aperture place that wherein said pull bar 7 penetrates shroud 1 arranges the 3rd seal ring 3.
Described first seal ring 5, second seal ring 9 and the 3rd seal ring 3 are O type circle.
During work: the inwall due to shroud 1 is provided with the first seal groove 4; can with the external cylindrical surface fitted seal of SEALING FITTING; in time closing shrouding 6; air in shroud can be extracted from vacuumizing connection mouth 2; in time pulling pull bar 7; vacuum pumping device gets final product the air in evacuation container chuck, reaches the effect of duplicate protection sealing.
The beneficial effect of the present embodiment is: the sealability of sealed joint apparatus when ensureing that pressurized container vacuumizes, increases sealing contact surface, thus reaches the effect improving and vacuumize efficiency.
