Compared with the existing technology, the utility model has the beneficial effects that: the resistance to oil reservoir double-deck by setting, it is made to include
Nitrile rubber layer positioned at internal layer and the politef band wrapping layer positioned at outer layer, functioning as nitrile rubber are main resistance to
Oil reservoir, because nitrile rubber has polarity, if there is excellent resistance to nonpolarity and polarity oils and solvent；Politef
Band wrapping layer can provide most preferably due to having good high-low temperature resistant, corrosion-resistant and fire resistance characteristic for nitrile rubber layer
Protection, the fuel tolerance capability and service life in adverse circumstances are significantly improved, and design by special structure, so that butyronitrile rubber
Glue-line and casing play sealing cooperate, and sealing effect is good, can effectively prevent oil, water or other liquid enter in tube body, inner glue layer and
ZFDB type Self-fticking fireproof packing strip between casing play has the characteristic of high fire-retardance, self-adhesion, tension, the utility model structure jail
Gu, fire-resistant waterproof, temperature classification are high, sealing effect is good, have high oil resistance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refering to Figure 1, a kind of oil-resistant high temperature-resistanrubber rubber pipe provided by the utility model, including outer glue-line 1, inner glue layer
2 and positioned at casing play 3 between the two, packet is equipped with one layer of ZFDB type Self-fticking fireproof packing strip between inner glue layer 2 and casing play 3
4, outer glue-line 1 is the resistance to oil reservoir of double-layer structure, including being located at the nitrile rubber layer 11 of internal layer and positioned at the politef of outer layer
Band wrapping layer 12, the outer circumference portion of casing play 3 is concentric to be uniformly convexly equipped with several sealing strips 31, the cross sectional shape of sealing strip 31
