Elbow connecting pipe fitting

Abstract

The invention discloses an elbow connecting pipe fitting which comprises a pipe body. Connecting ports are formed at the two ends of the pipe body. The inner diameter of each connecting port is equal to the outer diameter of the pipe body. A shock-resisting layer is arranged on the upper portion of the inner wall of the pipe body and is 0.8 cm thick. The thickness oftwo ends of the shock-resisting layer is reduced gradually until the two ends are in smooth connection with the inner wall of the pipe body. According to the elbow connecting pipe fitting, the shock-resisting layer can guarantee that an elbow does not be deformed under shock, and the shock-resisting layer becoming thin gradually can be well attached to the interior of an elbow body so that gas or liquid can pass through the pipe fitting smoothly and stably. The shock-resisting layer at the interior of the pipe body does not cover the inner wall of the pipe body completely, so that the production cost is relatively low.

Description

technical field [0001] The invention relates to connecting pipe fittings, in particular to a connecting pipe fitting. Background technique [0002] The existing elbow connection pipe fittings are all common elbows. Gas or liquid enters the elbow from one end of the pipe, often causing impact on the elbow due to excessive pressure. Long-term impact will cause the elbow to deform, causing the liquid or gas to It is unstable when passing through the elbow, and if a hard impact-resistant layer is added inside the entire elbow, the cost will be too high. Contents of the invention [0003] The object of the present invention is to provide an elbow connecting pipe fitting, which is not easily deformed and has low production cost. [0004] The present invention is realized through the following technical solutions: an elbow connection pipe fitting, including a pipe body, two ends of the pipe body are provided with connection ports, the inner diameter of the connection port is equ...
