Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a high-strength PVC anti-pressure corrugated pipe that can reduce friction, which solves the need to connect two sections of corrugated pipes in the actual use process. During the connection process, due to excessive water flow If the size is large, it will cause water leakage at the joint and poor sealing effect.

Abstract

The invention discloses a high-strength PVC compression-resistant corrugated pipe capable of reducing friction, and the corrugated pipe comprises two symmetrically-arranged PVC corrugated pipe bodies, a reinforcing buffer layer is fixed to the inner wall of each PVC corrugated pipe body, a polytetrafluoroethylene layer is fixed to the inner wall of each reinforcing buffer layer, and a connecting sleeve is arranged between the surfaces of the two PVC corrugated pipe bodies in a sleeving mode. The connecting sleeve is provided with an adaptive adjusting sealing mechanism, and a positioning mechanism is arranged between the PVC corrugated pipe body and the connecting sleeve. The invention relates to the technical field of corrugated pipes. According to the high-strength PVC compression-resistant corrugated pipe capable of reducing friction, the compression resistance of the PVC corrugated pipe bodies can be improved conveniently through the arrangement of the reinforcing buffer layers, the friction of the inner wall of the PVC corrugated pipe bodies can be reduced through the arrangement of the polytetrafluoroethylene layers, water drainage is smoother, sealing can be automatically achieved conveniently according to the water flow through the arrangement of the adaptive adjusting sealing mechanism, the larger the water flow is, the more tight sealing is achieved, the sealing effect is effectively improved, and the water leakage phenomenon is prevented.

Description

technical field [0001] The invention relates to the technical field of bellows, in particular to a high-strength PVC pressure-resistant bellows that can reduce friction. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. Bellows are widely used in instruments and meters, and their main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, and the measurement range is tens of Pa to tens of MPa. Its open end is fixed, and the sealed end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. When working, under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end d...
