For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of pressure vessel, with strengthening vibration-resistance thermoelectric couple sleeve pipe, comprises blind flange; Also comprise sleeve pipe and the support component of at least one; Sleeve pipe is connected with blind flange, and support component is fixed on the outside surface of sleeve pipe;
Wherein, described support component comprises at least three support units, and described support unit is evenly distributed on the outside surface of sleeve pipe.
Thermocouple sheath of the present utility model, in use, is connected with original pipe connecting flange on required measuring equipment by blind flange, and this thermocouple sheath is packed in adapter, is finally fixed on the equipment of required measurement.
Sleeve pipe in the utility model comprises the tube unit of at least one section; Described tube unit is multi-section combined structure.The sleeve pipe that the utility model is grown for length, the multi-section combined structure that sleeve pipe is divided into some sections of tube units by employing realizes, and respectively every section of tube unit boring is shaped.Section is determined the specification of blanking bar according to the outside diameter of every section, to save material.The utility model is adjacent is fixed into an entirety by the mode of welding between tube unit between two.When welding, tube unit endoporus insert one section with the metal bar of not melting welding of tube unit material, adopt frock to fix at the outside surface of tube unit simultaneously, with the linearity that guarantees tube unit endoporus with prevent welding deformation.
The utility model pressure vessel is with strengthening in vibration-resistance thermoelectric couple sleeve pipe, and described support unit adopts can play a supporting role equal of the prior art can be applied in the utility model structure, but the preferential support unit that adopts following structure of the utility model.
Support unit comprises through hole double-screw bolt, blind nut, support bar and flexible member; One end of described through hole double-screw bolt is fixed on the outside surface of sleeve pipe, and its other end is connected with blind nut by screw thread pair; Flexible member and support bar are arranged in through hole double-screw bolt, and one end of flexible member contacts with the outside surface of sleeve pipe, and the other end of flexible member contacts with support bar.The bottom of the support bar in the support unit that the utility model adopts is not directly welded on the outside surface of sleeve pipe, but contacts with the outside surface of sleeve pipe by flexible member; The top of support bar contacts with original nozzle inner wall on required measuring equipment, and sleeve pipe is well supported, and effectively prevents the vibration producing at work.Support bar is realized the adjusting of support bar height by blind nut and through hole double-screw bolt, effectively play a supporting role.Flexible member described in this support unit preferentially adopts spring of the prior art.
The utility model is compared with prior art: in sum, pressure vessel described in the utility model evenly arranges a kind of support unit with spring with strengthening vibration-resistance thermoelectric couple sleeve pipe around sleeve pipe, when installation, the support bar of support unit is depressed, pushed easily in adapter.Owing to being provided with support unit, thermocouple sheath, in the time being subject to fluid vortex induced vibration, plays good supporting role.Reduce the intrinsic installation free-running frequency of sleeve pipe, avoided the fatigue break of sleeve pipe.The sleeve pipe of growing for length adopts subsection hole-drilling processing, when welding, inserts a metal bar to guarantee the precision of endoporus at endoporus.
