Problem improves the safety and service life of oil delivery hose.
A kind of rubber hose resistant to chemical etching, including tube body and buckle press joint, buckle press joint are mounted on one of tube body
On port, which is characterized in that tube body includes the mesoglea between inner glue layer and outer glue-line and inner glue layer and outer glue-line, middle glue
It is door curtain made of cloth layer between layer and outer glue-line, is also door curtain made of cloth layer between mesoglea and inner glue layer, the inside of inner glue layer also has a strata
Vinyl film.
The utility model has the beneficial effects that improving the erosion-resisting ability of oil delivery hose, keeps oil delivery hose safer, prolong
Service life has been grown, layer of polyethylene film specifically has been set in the inside of inner glue layer, using ultra-high molecular weight polyethylene film
As the internal layer of rubber hose resistant to chemical etching, there is excellent chemical resistance, in addition to strong oxidizing property acid solution, certain
Temperature and concentration range in be resistant to various corrosive medias (acid, alkali, salt) and organic solvent.
Spiral wire built in the mesoglea.High strength helical steel wire assigns rubber hose can be dual-purpose with suction, Ji Neng
Medium is aspirated under negative pressure, it can also pumped (conveying) medium under pressure.
The inner glue layer is made by nitrile rubber.
The door curtain made of cloth layer is made by polyester fiber.
The buckle press joint includes the interconnecting piece of connection pipe body, and interconnecting piece is formed by withholding set and inner core, withholds set and fixes
On inner core outer peripheral surface, withholds to be formed between set and inner core and accommodate oil delivery hose wall and withhold slot.
Described withhold forms annular flange on set inner wall, and arcuate bottom is formed on the bottom for withholding slot.
The sub- flange that annular lateral dimension is less than flange inner peripheral surface lateral dimension is formed on the inner peripheral surface of the annular flange.
The quil of several annular arrays is also set up on the inner wall for withholding set, the tip inclination direction of quil withholds slot
Bottom.
Two annular hoops are set on the outer peripheral surface for withholding set, two hoops respectively with annular flange and annular array
Quil is corresponding.
The tail end for withholding set forms the opotism structure turned up.
Buckle press joint has the function of good leakproofness and firm fixation sebific duct, is such as withholding setting annular inside set
It is lesser that lateral dimension is arranged in flange, extruding oil pipeline wall that can be closer especially on the inner peripheral surface of annular flange
Sub- flange, sub- flange can be smoothly embedded in oil pipeline wall, form better seal effect.
It is also set up on the inner wall for withhold set to the inclined several quils of trench bottom are withheld, quil is pierced into oil pipeline wall
It is interior, prevent oil pipeline wall from falling off.Opotism structure plays a protective role, and prevents the outer wall of oil pipeline from wearing.Slot is withheld to be formed
Arcuate bottom avoids bottom stress concentration from causing to be broken.
It elaborates with reference to the accompanying drawings and examples to the utility model.
