End, each disc with the orientation of big opening end to osculum end with rubber hose medium flow to it is identical.
The rubber hose that above-mentioned high abrasion low resistance loss arbitrarily can bend, the medial extremity of two fuses are pressed respectively positioned at end
Two discs, each internal diameter at disc osculum end matched with the internal diameter of fuse, and the external diameter of each disc big opening end is soft with rubber
The internal diameter matching of tube body.
The rubber hose that above-mentioned high abrasion low resistance loss arbitrarily can bend, the physical dimension of each disc are consistent, each disc side wall
Inclination angle a be 38-45 °, the thickness b of each disc side wall is 2-6 millimeters.
The rubber hose that above-mentioned high abrasion low resistance loss arbitrarily can bend, the big opening end edge-light of each disc side wall are slipped over
Cross.
The rubber hose that above-mentioned high abrasion low resistance loss arbitrarily can bend, the rubber hose body two ends are connected with each fuse
Place's suit withholds sleeve pipe, locks rubber hose body with each fuse by sleeve pipe is withheld.
The rubber hose that above-mentioned high abrasion low resistance loss arbitrarily can bend, the rubber hose body are provided with steel wire reinforcement layer,
Steel wire reinforcement layer is located at the middle part of rubber hose body wall.
The present invention is for solving the problems, such as that existing rubber hose wearability is low, the short knot to General Purpose Rubber flexible pipe of service life
Structure is improved, and sets up wear-resistant liner, disc of the wear-resistant liner by multiple marshallings in rubber hose chamber body
Constitute, the direction of each disc large port to portlet with rubber hose medium flow to it is identical.After improvement the characteristics of the present invention
It is as follows：1st, the wear-resistant liner antiwear property being made up of disc is greatly improved, and is reduced drag losses, is improve rubber hose
Service life；2nd, each disc of marshalling is separate, it is ensured that rubber hose arbitrarily bends unrestricted；3rd, can be with root
It is different according to circulation medium, disc is made from the different metal material of hardness or nonmetallic materials, to realize ruggedness and economy
The best combination of property；4th, improve the bearing capacity of rubber hose；5th, dish structure shape can effectively prevent dielectric deposition and fall
Stream.With relatively low cost input, the present invention successfully solves the problems, such as that rubber hose wearability is low, it is adaptable to the row such as metallurgy, Ore
Industry conveying high rigidity powder, the occasion of particulate material.
