Description
Technical field
The utility model relates to a kind of for the storage tank of more than 20m3 and the vacuum pumping device of tank car, particularly relates to a kind of large pressurized vessel 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 large pressurized vessel to vacuumize sealed joint apparatus, reasonable in design, be applicable to storage tank and the tank car of more than 20m3, 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 large pressurized vessel vacuumizes sealed joint apparatus, comprises shroud and SEALING FITTING, described shroud is fixedly installed and vacuumizes interface; The external cylindrical surface of described SEALING FITTING sets gradually some seal grooves, each described seal groove is all sealed and matched by the first seal ring and described shroud; Slide in wherein said shroud inner chamber and be provided with shrouding, a pull bar passes the aperture of described shroud and is connected and fixed with one end of described shrouding; In described SEALING FITTING, one end of pipe is arranged with the suitable interior step of described shrouding and described interior step is wide at the top and narrow at the bottom.
Be as further improvement of the utility model: the plane place of described interior step is fixedly installed the second seal ring.
Be as further improvement of the utility model: the aperture place that described pull bar penetrates described 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.
Be as further improvement of the utility model: the external cylindrical surface of described SEALING FITTING sets gradually three seal grooves.
During utility model works: first the SEALING FITTING vacuumized is connected with pressurized container Outer Tube vacuum orifice, then connection mouth will be vacuumized be connected with vacuum pumping device; First with shrouding, joint 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, easy to operate, are applicable to storage tank and the tank car of more than 20m3, ensure sealability when pressurized container vacuumizes, increase sealing contact surface, thus reach the effect improving and vacuumize efficiency.
Accompanying drawing explanation

Wherein 1-shroud, 2-SEALING FITTING, 3-vacuumize step in interface, 4-seal groove, 5-first seal ring, 6-shrouding, 7-pull bar, 8-, 9-second seal ring, 10-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 large pressurized vessel of the present embodiment vacuumizes sealed joint apparatus, comprise shroud 1 and SEALING FITTING 2, described shroud 1 is fixedly installed and vacuumizes interface 3; The external cylindrical surface of described SEALING FITTING 2 sets gradually three seal grooves 4, each described seal groove 4 is all sealed and matched with described shroud 1 by the first seal ring 5; Slide in wherein said shroud 1 inner chamber and be provided with shrouding 6, a pull bar 7 passes the aperture of described shroud 1 and is connected and fixed with one end of described shrouding 6; In described SEALING FITTING 2 one end of pipe arrange with the suitable interior step 8 of described shrouding 6 and described interior step 8 in wide at the top and narrow at the bottom.
The plane place of described interior step 8 is fixedly installed the second seal ring 9.
The aperture place that described pull bar 7 penetrates described shroud 1 arranges the 3rd seal ring 10.
Wherein said first seal ring 5, second seal ring 9 and the 3rd seal ring 10 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, joint 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, reach the effect of sealed knot.
The beneficial effect of the present embodiment is: reasonable in design, makes simple, easy to operate, is applicable to storage tank and the tank car of more than 20m3, ensures sealability when pressurized container vacuumizes, increases sealing contact surface, thus reach the effect improving and vacuumize efficiency.
