Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] The stainless steel-lined composite pipe fitting of the present invention, through the inner sealing surface and the end face sealing surface, realizes the double insurance of sealing when the pipe fitting is connected with the inner stainless steel pipe, makes up for structural defects, and ensures that the fluid in the pipe only contacts the stainless steel layer and does not touch the outer surface. Lamma steel pipe fittings, truly exert the excellent performance of stainless steel in fluid transportation, while prolonging the service life of pipe fittings, improve the transportation efficiency, ensure the safety of transportation, and ensure the hygienic indicators of water,
[0030] Such as figure 1 As shown, the first embodiment of the stainless steel-lined composite pipe fitting of the present invention includes an outer malleable steel pipe fitting 1, a ...

The invention discloses a liner stainless steel composite pipe fitting. The liner stainless steel composite pipe fitting comprises an outer layer malleable cast iron pipe fitting body, a fixing body, a stainless steel lining layer and a sealing ring, wherein the stainless steel lining layer is fixed to the inner wall of the outer layer malleable cast iron pipe fitting body through the fixing body, the sealing ring is arranged at the end of the fixing body and located at the joint portion of the outer layer malleable cast iron pipe fitting body, the sealing ring comprises a sealing ring body and a taper boss, the taper boss is arranged at the front end of the sealing ring body, an end face sealing face used for end face sealing is reserved at the front end of the sealing ring body, and the inclined plane of the taper boss is an inner sealing face used for side face sealing. According to the liner stainless steel composite pipe fitting, through the inner sealing face and the end face sealing face, the double insurance of sealing when the pipe fitting is connected with a liner stainless steel pipe, it is guaranteed that fluid in the tube only makes contact with the stainless steel layer rather than making contact with the outer layer malleable cast iron pipe fitting body, and the hygienic index of water using is guaranteed. Meanwhile, the installation is convenient, the installation level and the responsibility of operating personnel are not over-depended, and the good application prospect is achieved.
Description
technical field [0001] The invention relates to the technical field of anti-corrosion pipe fittings, in particular to a composite pipe fitting lined with stainless steel. Background technique [0002] In order to improve the quality of drinking water and prevent some elements harmful to human body from entering drinking water due to long-term corrosion of the inner wall of metal pipe fittings by water and endangering human health, stainless steel water delivery pipes have been widely used. At present, the sealing mechanism of the pipe fittings used for pipeline connection is not perfect enough. When the pipe fittings are connected to the pipe fittings or the pipe fittings are connected to the pipes, the threaded connection in the pipe fittings cannot completely guarantee the tightness of the sealing ring, which will easily cause the end surface of the pipe to corrode, rust, and the pipe end After rusting, drinking water will be polluted, resulting in unqualified sanitary con...
