High-elasticity and high-wear-resistant extrusion exhausting peristaltic tube

Abstract

The invention discloses a high-elasticity and high-wear-resistant extrusion exhausting peristaltic tube which sequentially comprises an inner rubber layer, an inner reinforcing layer, a first middle rubber layer, a middle reinforcing layer, a second middle rubber layer, an outer reinforcing layer and an outer rubber layer from inside to outside, and the inner reinforcing layer, the middle reinforcing layer and the outer reinforcing layer are all cord thread winding layers. The high-elasticity and high-wear-resistant extrusion exhausting peristaltic tube is reasonable in design and simple in structure, has the advantages of high wear resistance, high toughness, strong fracturing resistance, corrosion resistance and aging resistance, is long in service life and has the promotion significance.

Description

technical field [0001] The invention belongs to the technical field of pipe fittings, and in particular relates to a high-elasticity and high-wear-resistance extrusion suction peristaltic pipe. Background technique [0002] At present, the national real estate is prosperous for a long time. On the extrusion and pressure discharge mortar pump used in construction sites or pumping stations, there is an accessory, that is, the concrete pump hose, the suction and discharge of cement mortar and other concrete, and the iron and steel and mining industries, power equipment. In the sealed box, the extruded peristaltic tube conveying liquid medium is resistant to extrusion and dynamic bending. It is required that the pipe body has small deformation under pressure and good extrusion resistance. The rubber layer has excellent elasticity and wear resistance. The burst pressure of the hose is low. It is lower than three times the working pressure, but traditional products have poor elast...

[0002] At present, the national real estate is prosperous for a long time. On the extrusion pressure discharge mortar pump used in construction sites or pumping stations, there is an accessory, that is, the concrete pump hose, the suction and discharge of cement mortar and other concrete, and the iron and steel and mining industries, power equipment. In the sealed box, the extruded peristaltic tube conveying liquid medium is resistant to extrusion and dynamic bending. It is required that the pipe body has small deformation under pressure and good extrusion resistance. The rubber layer has excellent elasticity and wear resistance. The burst pressure of the hose is low. It is lower than three times the working pressure, but traditional products have poor elasticity and wear resistance, short service life, and need to be replaced frequently, which has brought great obstacles to construction efficiency and progress
