Abstract
The invention discloses an evacuation device of a low-temperature insulated liquid storage tank and belongs to the field of chemical industry. The device consists of a rotary shaft (9), a steel pipe I (5), a steel pipe II (12), a sleeve (6), a pressing cover (7), the sleeve (6), a combined sealing piece (8), a flange I (4) and a flange II (11), wherein the rotary shaft (9) is connected with a handle (10). The device is characterized in that: the rotary shaft (9) which is connected with the handle (10) passes through the pressing cover (7), the combined sealing piece (8), the steel pipe I (5) and the flange I (4) respectively and is in threaded connection with a tapered plug (1) of a sealing device on a tank body; the sleeve (6) is in fixed connection with the steel pipe I (5) and in threaded connection with the pressing cover (7); the steel pipe I (5) is connected with the flange I (4) fixedly; the steel pipe II (12) is in fixed connection with the steel pipe I (5) and in threaded connection with the flange II (11); and the combined sealing piece (8) is arranged in the sleeve (6). The device is connected with the storage tank by the flanges, so that the device is reusable, resources are saved, and the cost of a manufacturer can be reduced effectively.
Description
Technical field
The present invention relates to a kind of vacuum pumping device of Cryo Heat Insulation liquid storage tank, belong to chemical field.
Background technique
The producer of domestic existing production Cryo Heat Insulation liquid storage tank, its basin generally is directly to offer valve on the storage tank seal arrangement with vacuum pumping device, is connected with the vacuum machine by valve, reaches the purpose that tank body vacuumizes.Vacuum pumping device just stretches out outside the basin like this, and damage easily bumps in transportation and installation process.Vacuum pumping device belongs to can reuse parts, and every product all disposes one, certainly will cause the waste of resource and the increase of cost of production.
Summary of the invention
Problem to be solved by this invention is the deficiency at above-mentioned existence, and a kind of vacuum pumping device of not establishing valve and can reusing on the tank body seal arrangement is provided.
Realize that technological scheme of the present invention forms the vacuum pumping device cavity by steel pipe I 5, steel pipe II 12, sleeve 6, gland 7, combination seal 8, flange I 4, flange II 11, the rotating shaft 9 that it is characterized in that being connected with flexible handle 10 tapered plug 1 of the seal arrangement on overpressure cap 7, combination seal 8, steel pipe I 5, flange I4 and the tank body respectively is threaded; One end and the steel pipe I 5 of sleeve 6 are fixed, and the other end is threaded with gland 7; Steel pipe I5 and flange I 4 are fixed; An end and the steel pipe I 5 of steel pipe II 12 are fixed, and the other end is threaded with flange II 11.Combination seal 8 places in the sleeve 6.
This vacuum pumping device is threaded by the tapered plug 1 on rotating shaft 9 and the tank body seal arrangement, when vacuumizing or after finishing, accomplishes to mention tapered plug 1 and leaves tapered sleeve 2 or promote tapered plug 1 and cooperate with tapered sleeve 2.
This vacuum pumping device is connected with the bolt of flange III3 by flange I 4 and being threaded of the tapered sleeve 2 of flange III3 and tank body upper sealing device finished and being connected and separating of tank body.
This device adopts flange to be connected with basin, can accomplish recycling, economizes on resources, and can effectively reduce the cost of manufacturer.
Description of drawings
Accompanying drawing is a sectional view of the present invention.
Embodiment
The present invention will be described below in conjunction with accompanying drawing.
Be connected with rotating shaft 9 difference overpressure cap 7, combination seal 8, steel pipe I 5, the flange I 4 of flexible handle 10; Sleeve 6 is fixed with steel pipe I 5, is threaded with gland 7; Flange I 4 and steel pipe I 5 are fixed; Steel pipe II12 and steel pipe I 5 are fixed, are threaded with flange II 11.Combination seal 8 places in the sleeve 6.Vacuum pumping device is formed in each parts assembling back.
The bolt of this vacuum pumping device by flange I 4, III3 connects and being threaded of flange III3 and tapered sleeve 2, finish with tank body on being connected and separating of sealing configuration.Handle with sleeve 10 by being threaded of rotating shaft 9 and tapered plug 1, is mentioned tapered plug 1, flange II 11 with start working after evacuator is connected.Vacuumize finish after, handle with sleeve 10 promotes tapered plugs 1 by rotating shaft 9 and tapered sleeve 2 cooperates.Turn flange I 4, III3 can take off vacuum pumping device.
