Title
(EN) LOW-TEMPERATURE-RESISTANT AND IMPACT-RESISTANT PVC PIPELINE
(FR) PIPELINE EN PVC RÉSISTANT AUX BASSES TEMPÉRATURES ET RÉSISTANT AUX CHOCS
(ZH) 一种耐低温抗冲击型PVC管道
Abstract
(EN) A low-temperature-resistant and impact-resistant PVC pipeline, comprising a first protective pipe (1); several first fixing blocks (2) is provided on the outer surface of the first protective pipe; the front faces of the two first fixing blocks on the same side are movably connected to the bottom ends of two connection rods (3) respectively by means of pin shafts, the top ends of the connection rods are movably connected to the front faces of second fixing blocks (4) by means of pin shafts, and the upper surfaces of the two second fixing blocks are fixedly connected to the lower surface of a buffer mechanism (5). By providing the first protective pipe, the connection rods, a movable sleeve (51), a fixing rod (52) and a spring (53), when the interior of a PVC pipeline (12) is impacted, the PVC pipeline drives the first protective pipe to move, so that the movable sleeve drives the spring to stretch, thus the retracted spring absorbs an impact force on the PVC pipeline, and the PVC pipeline is not easily damaged under the action of the impact force, avoiding replacement caused by damage.
(FR) Pipeline en PVC résistant aux basses températures et résistant aux chocs, comprenant un premier tuyau de protection (1) ; plusieurs premiers blocs de fixation (2) sont disposés sur la surface extérieure du premier tuyau de protection ; les faces avant des deux premiers blocs de fixation sur le même côté sont reliées de façon mobile aux extrémités inférieures de deux tiges de liaison (3) respectivement au moyen d'axes de broche, les extrémités supérieures des tiges de liaison sont reliées de façon mobile aux faces avant des seconds blocs de fixation (4) au moyen d'arbres de broche, et les surfaces supérieures des deux seconds blocs de fixation sont reliées de manière fixe à la surface inférieure d'un mécanisme tampon (5). En fournissant le premier tuyau de protection, les tiges de liaison, un manchon mobile (51), une tige de fixation (52) et un ressort (53), lorsque l'intérieur d'un pipeline en PVC (12) est impacté, le pipeline en PVC amène le premier tuyau de protection à se déplacer, de sorte que le manchon mobile amène le ressort à s'étirer, ainsi, le ressort rétracté absorbe un choc sur le pipeline en PVC, et le pipeline en PVC n'est pas facilement endommagé sous l'action du choc, évitant un remplacement provoqué par un endommagement.
(ZH) 一种耐低温抗冲击型PVC管道,包括第一防护管(1),第一防护管的外表面设置有若干个第一固定块(2),同一侧面两个第一固定块的正面均通过销轴分别与两个连接杆(3)的底端活动连接,连接杆的顶端通过销轴与第二固定块(4)的正面活动连接,两个第二固定块的上表面与缓冲机构(5)的下表面固定连接;通过设置第一防护管、连接杆、活动套(51)、固定杆(52)和弹簧(53),使PVC管道(12)的内部受到冲击时,PVC管道带动第一防护管运动,使得活动套带动弹簧伸长,使得收缩的弹簧对PVC管道受到的冲击力进行吸收,使得PVC管道不易在冲击力的作用下损坏,避免了因损坏而更换。
