The group of adjustable type level instrumentation nozzle flange is to device
Technical field
The utility model relates to pressure vessel, particularly relates to a kind of group of adjustable type level instrumentation nozzle flange on pressure vessel to device.
Background technology
In Pressure Vessel Manufacture Process, major part container all needs to install liquid level gauge, because liquid level gauge group is very accurate to requiring, positive and negative between General Requirements liquid level gauge two flange can not more than 1mm, and, also to ensure that stretching out of upper and lower two flanges is highly consistent, meanwhile, make the center of flange hole point-blank.Before group is to liquid level gauge, first will do frock in the past, and use I-steel according to the size of liquid level gauge flange exactly, on I-steel, setting-out draws the position of liquid level gauge flange upper bolt hole, then, then holes with drilling machine.Deng group pair time, first two flanges are fixed by bolts on I-steel and are being grouping, to ensure right accurate of level instrumentation nozzle flange group.But, due to the spacing of liquid level gauge two flange, great majority are all unequal, so, need the frock making multiple different size according to liquid level gauge size, such light setting-out jewel hole on I-steel must be used up a lot of time, and, wait this group liquid level gauge group to after completing, when group is to next group liquid level gauge, also may be inconsistent due to size, cause I-steel not employ.
Utility model content
Main purpose of the present utility model is the above-mentioned shortcoming overcoming prior art existence, and provide a kind of group of adjustable type level instrumentation nozzle flange to device, its structure is simple, easy to operate, by regulating the position of sliding sleeve on supervisor, can not only be grouping the level instrumentation nozzle flange of different size, and, do not need the frock making different size according to liquid level gauge size; Greatly save the time of material cost and making frock.
The purpose of this utility model is realized by following technical scheme:
A kind of group of adjustable type level instrumentation nozzle flange is to device, it is characterized in that: comprising: a fixed structure, be sleeved on slide construction outside fixed structure, wherein, fixed structure is made up of a supervisor and the mounting flange be arranged on supervisor, and this supervisor is provided with several adjustment hole; Slide construction is formed by the sliding sleeve be sleeved on outside supervisor, the slip flange be arranged on above sliding sleeve, and is provided with an installing hole above this sliding sleeve; One bolt, is fixed by nut after the adjustment hole on supervisor through this installing hole and correspondence.
Described supervisor, sliding sleeve are steel pipe.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, its structure is simple, easy to operate, by regulating the position of sliding sleeve on supervisor, can not only be grouping the level instrumentation nozzle flange of different size, and, do not need the frock making different size according to liquid level gauge size; Greatly save the time of material cost and making frock, the group of more than 200% can have been saved to the time relative to former frock.

Detailed description of the invention
As shown in Fig. 1-Fig. 4, the utility model comprises: fixed structure 1, be sleeved on slide construction 2 outside fixed structure 1, wherein, the mounting flange 12 that fixed structure 1 is arranged on supervisor 11 by a supervisor 11 and employing welding manner forms, and this supervisor 11 is provided with several adjustment hole; The slip flange 22 that slide construction 2 is arranged on above sliding sleeve 21 by the sliding sleeve 21 be sleeved on outside supervisor 11, employing welding manner forms, and this sliding sleeve 21 is provided with an installing hole above; Bolt 23 is through after installing hole and the adjustment hole of correspondence on supervisor 11, and fastening nut 24 is fixed.
Above-mentioned supervisor 11, sliding sleeve 21 are steel pipe.
During use, adjust the spacing between the utility model mounting flange 12 and slip flange 22, and fixed by bolt 23, nut 24; Then, by bolt, prefabricated upper and lower pipe connecting flange is connected with mounting flange 12 of the present utility model, slip flange 22; Again upper and lower pipe connecting flange is stretched to device aperture position, with baffle plate location, spot welding is fixed, welding fabrication; After welding bead cooling, then remove the utility model.
Above-mentioned flange is prior art, and the technology of not specified (NS) is prior art, therefore repeats no more.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
