Abstract
The utility model provides a kind of small pressure container to vacuumize sealed joint apparatus, comprises shroud and SEALING FITTING; Described shroud is fixedly installed and vacuumizes connection mouth; Set gradually some the first seal grooves in the inwall of described shroud, each described first seal groove is all sealed and matched by the first seal ring and described SEALING FITTING; 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 other end of described shrouding and the interior step cooperation place of described SEALING FITTING arrange the second seal groove; In described second seal groove, the second seal ring is set.The beneficial effects of the utility model: reasonable in design, make simple, can be used in taking out of the storage tank of below 20m3 true, ensure sealability when pressurized container vacuumizes, increase sealing contact surface, thus reach the effect improving and vacuumize efficiency.
Description
Technical field
The utility model relates to a kind of vacuum pumping device of the storage tank for below 20m3, particularly relates to a kind of small pressure container and vacuumizes sealed joint apparatus.
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, a kind of seal arrangement must be designed when vacuumizing, ensureing sealing.
Model utility content
The utility model provides a kind of small pressure container to vacuumize sealed joint apparatus, reasonable in design, make simple, easy to operate, can be used in taking out of the storage tank of below 20m3 true, ensure sealability when pressurized container vacuumizes, increase sealing contact surface, thus reach the effect improving and vacuumize efficiency.
The utility model is achieved through the following technical solutions: a kind of small pressure container vacuumizes sealed joint apparatus, comprises shroud and SEALING FITTING; Described shroud is fixedly installed and vacuumizes connection mouth;
Set gradually some the first seal grooves in the inwall of described shroud, each described first seal groove is all sealed and matched by the first seal ring and described SEALING FITTING; 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 other end of described shrouding and the interior step cooperation place of described SEALING FITTING arrange the second seal groove; In described second seal groove, the second seal ring is set.
Be as further improvement of the utility model: described pull bar penetrates shroud aperture place and 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.
Be as further improvement of the utility model: in the inwall of described shroud, set gradually two described first seal grooves.
Working principle: first SEALING FITTING is connected with pressurized container Outer Tube vacuum orifice, then connection mouth will be vacuumized be connected with vacuum pumping device; First with shrouding, SEALING FITTING is blocked, vacuum pumping device is first by the air extraction in shroud, make to reach vacuum level requirements in shroud, then pull pull bar, vacuum pumping device can extract the air in pressurized container chuck, make to reach vacuum level requirements in pressurized container chuck, when degree of vacuum reaches requirement in pressurized container chuck, close shrouding, then vacuum pumping device is unloaded, shut and vacuumize connection mouth, reach the effect of sealed knot.
The beneficial effects of the utility model: reasonable in design, make simple, can be used in taking out of the storage tank of below 20m3 true, ensure sealability when pressurized container vacuumizes, increase sealing contact surface, thus reach the effect improving and vacuumize efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the exploded view of Fig. 1;
Wherein 1-shroud, 2-SEALING FITTING, 3-vacuumize step in connection mouth, 4-first seal groove, 5-first seal ring, 6-shrouding, 7-pull bar, 8-, 9-second seal groove, 10-second seal ring, 11-the 3rd seal ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, 2: a kind of small pressure container of the present embodiment vacuumizes sealed joint apparatus, comprise shroud 1 and SEALING FITTING 2, described shroud 1 is fixedly installed and vacuumizes connection mouth 3; Set gradually two the first seal grooves 4 in the inwall of described shroud 1, each described first seal groove 4 is all sealed and matched with described SEALING FITTING 2 by 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 other end of described shrouding 6 and interior step 8 cooperation place of described SEALING FITTING 2 arrange the second seal groove 9; In described second seal groove 9, the second seal ring 10 is set.
Described pull bar 7 penetrates shroud 1 aperture place and arranges the 3rd seal ring 11.
Described first seal ring 5, second seal ring 10 and the 3rd seal ring 11 are O type circle.
During work: first SEALING FITTING 2 is connected with pressurized container Outer Tube vacuum orifice, then connection mouth 3 will be vacuumized be connected with vacuum pumping device; First with shrouding 6, SEALING FITTING 2 is blocked, vacuum pumping device is first by the air extraction in shroud 1, make to reach vacuum level requirements in shroud 1, then pull pull bar 7, vacuum pumping device can extract the air in pressurized container chuck, make to reach vacuum level requirements in pressurized container chuck, when degree of vacuum reaches requirement in pressurized container chuck, close shrouding 6, then vacuum pumping device is unloaded, shut and vacuumize connection mouth 3, reach the effect of sealed knot.
The beneficial effect of the present embodiment is: reasonable in design, makes simple, can be used in taking out of the storage tank of below 20m3 true, ensures sealability when pressurized container vacuumizes, increases sealing contact surface, thus reach the effect improving and vacuumize efficiency.
