Description
Technical Field
The utility model relates to a pipeline compensator technical field, concretely relates to single tetrafluoro compensator of ventilation plastics.
Background
The polytetrafluoroethylene corrugated pipe compensator is an indispensable key part for compensating displacement caused by expansion with heat and contraction with cold in an anticorrosive pipeline in the industries of nonferrous smelting, petrochemical industry, flue gas acid making and the like, wherein a Polytetrafluoroethylene (PTFE) corrugated pipe anticorrosive coating is a core part of the compensator. When the existing pipeline compensator compensates, the corrugated pipe body is easy to be damaged because the corrugated pipe is not limited to be compressed or stretched.
Disclosure of Invention
In order to solve the technical defect existing in the prior art, the utility model provides a single tetrafluoro compensator of ventilation plastics.
The utility model discloses a technical solution be: the utility model provides a single tetrafluoro compensator of ventilation plastics, includes the PTFE bellows, PTFE bellows both ends all be equipped with the flange, flange and PTFE bellows both ends be connected and form bellows compensation structure, the flange at PTFE bellows both ends between still be equipped with compensation protection mechanism, compensation protection mechanism including setting up the spliced pole between the flange at PTFE bellows both ends, spliced pole and flange clearance fit, the spliced pole on be equipped with position sleeve, the flange at position sleeve and PTFE bellows both ends between spacing cooperation.
One end of the connecting column extends to the outer side of the flange and is limited through a limiting bolt, and the flange is in limiting fit with the limiting bolt.
And a negative pressure ring is arranged at the fold of the PTFE corrugated pipe.
The positioning sleeve is sleeved on the connecting column.
The limiting bolt is of a double-nut structure.
The flanges and the connecting columns are matched in a sliding mode.
The utility model has the advantages that: the utility model provides a single tetrafluoro compensator of ventilation plastics, including the PTFE bellows, PTFE bellows both ends all are equipped with the flange, the flange is connected with PTFE bellows both ends and is formed bellows compensation structure, still be equipped with compensation protection mechanism between the flange at PTFE bellows both ends, compensation protection mechanism is including setting up the spliced pole between the flange at PTFE bellows both ends, spliced pole and flange clearance fit, be equipped with position sleeve on the spliced pole, spacing cooperation between the flange at position sleeve and PTFE bellows both ends, through spliced pole cooperation position sleeve, when protection compensator produces the compression, it is spacing to compensate, through the two nut structures on the flange outer joint post, protection compensator is when tensile, can not lead to the PTFE bellows extension and damage the bellows unrestricted.
Drawings
Fig. 1 is a schematic view of the cross-sectional structure of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
The device comprises a PTFE corrugated pipe, a 2 flange, a 3 connecting column, a 4 negative pressure ring, a 31 positioning sleeve and a 32 limiting bolt.
Detailed Description
Now combine fig. 1, fig. 2 to explain further the utility model discloses a single tetrafluoro compensator of ventilation plastics, including PTFE bellows 1, 1 both ends of PTFE bellows all be equipped with flange 2, flange 2 be connected with 1 both ends of PTFE bellows and form bellows compensation structure, the flange 2 at 1 both ends of PTFE bellows between still be equipped with compensation protection mechanism, compensation protection mechanism including setting up spliced pole 3 between the flange 2 at 1 both ends of PTFE bellows, spliced pole 3 and 2 clearance fit of flange, spliced pole 3 on be equipped with position sleeve 31, position sleeve 31 cover establish on spliced pole 3. The locating sleeve 31 with the 1 flange at both ends of PTFE bellows 2 between spacing cooperation, the one end of spliced pole 3 extend to the 2 outsides of flange and spacing through spacing bolt 32, flange 2 and spacing bolt 32 between spacing cooperation. The limit bolt 32 is of a double-nut structure. Through spliced pole cooperation position sleeve, when the protection compensator produced the compression, it was spacing to compensate, through the two nut structures on the flange outer joint pole, the protection compensator can not lead to the unrestricted tensile and damage the bellows of PTFE bellows when tensile.
The fold of PTFE bellows 1 be equipped with negative pressure ring 4, effectively prevent the negative pressure that produces in the fan and inhale flat PTFE bellows.
The flange 2 is matched with the connecting column 3 in a sliding manner.
