Abstract
The utility model discloses a steel PTFE compensator. The steel PTFE compensator comprises an upper flange and a lower flange; a PTFE bellows and a stainless steel metal bellows are connected between the upper flange and the lower flange; the outer side of the PTFE bellows is sleeved with the stainless steel metal bellows; lug plates which are corresponding in position are arranged on the outer side wall of the upper flange and the outer side wall of the lower flange respectively; every two corresponding lug plates are connected through a stainless steel connecting rod. Because the outer side of the PTFE bellows is sleeved with the stainless steel metal bellows, the steel PTFE compensator can resist acids, alkalis and salts of various concentrations and has compression resistance of the stainless steel metal bellows. Besides, the steel PTFE compensator can resist a collision, thereby being long in service life.
Description
Technical field
The utility model relates to pipeline compensator technical field, relates in particular to a kind of steel tetrafluoro compensator.
Background technique
The working environment of pipeline compensator is very severe, and bear the environment of high temperature, need at present constantly to improve and make it have good resistance to high temperature and decay resistance, also to there is anti-pressure ability in addition, improve working life, existing pipeline compensator can not meet people's user demand, needs to improve.
Model utility content
The utility model object is exactly in order to make up the defect of prior art, and a kind of steel tetrafluoro compensator is provided.
The utility model is achieved through the following technical solutions:
A kind of steel tetrafluoro compensator, include upper and lower flange, between described upper and lower flange, be connected with tetrafluoro bellows and stainless steel metal bellows, described stainless steel metal bellows-sheathed is in the outside of tetrafluoro bellows, outer side wall at upper and lower flange is respectively equipped with the corresponding otic placode in position, and by stainless steel connecting rod, connects between corresponding otic placode.
The utility model has the advantages that: the utility model has stainless steel metal bellows at the outside cover of tetrafluoro bellows, can resistance to various concentration acid-alkali salts, have again the compression resistance of stainless steel metal bellows concurrently, be not afraid of collision, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of steel tetrafluoro compensator, include upper and lower flange 1,2, between described upper and lower flange 1,2, be connected with tetrafluoro bellows 3 and stainless steel metal bellows 4, described stainless steel metal bellows 4 is enclosed within the outside of tetrafluoro bellows 3, outer side wall at upper and lower flange 1,2 is respectively equipped with the corresponding otic placode 5 in position, and by stainless steel connecting rod 6, connects between corresponding otic placode 5.
