DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Embodiment 1, by Figure 1-4 The utility model relates to a high-life PPH pipe fitting resistant to acid and alkali corrosion, comprising a pipe fitting body 1, wherein a horizontal channel 101 and a vertical channel 102 which is relatively perpendicular to the horizontal channel 101 are formed inside the pipe fitting body 1, wherein a fixed ring 4 which is integrally connected to the inside of the vertical channel 102 is fixedly connected, and a protective member 2 is arranged on the fixed ring 4; the protective member 2 comprises a movable ring 201 located above the fixed ring 4, and elastic members 202 are symmetrically fixedly connected to the movable ring 201, and each elastic member 202 is fixedly connected to a protective block 203;

[0021] With this design, when the fluid falls from the vertical channel 102, the fluid first impacts the protective block 203 and does not directly impact the pipe body 1. At the same time, the elastic member 202 can reduce the instantaneous impact force of the fluid on the protective block 203, thereby protecting the protective block 203 and thus providing good protection for the pipe body 1.

[0022] The pipe body 1 is made of PPH material;

[0023] Such a design enables the pipe body 1 to have good acid and alkali corrosion resistance, thereby protecting the pipe body 1.

[0024] Both sides of the protection block 203 form arc-shaped surfaces 204, and the bottom outer wall of the protection block 203 is arc-shaped;

[0025] With this design, the direction of the fluid can be gradually changed through the arc surface 204 to avoid direct impact on the protective block 203 .

[0026] The elastic member 202 includes a telescopic rod, the top of the telescopic rod is fixedly connected to the movable ring 201 , and the bottom of the telescopic rod is fixedly connected to the protective block 203 .

[0027] A reinforcement member 3 is arranged on the outside of the pipe body 1. The reinforcement member 3 includes two reinforcement rings 301. A reinforcement block 302 is fixedly connected to each reinforcement ring 301. A semi-ring body 303 is fixedly connected to each reinforcement block 302. A locking ring 304 is arranged above the two semi-ring bodies 303. The external threads on the two semi-ring bodies 303 are threadedly connected to the internal threads on the locking ring 304.

[0028] This design makes it easy to put the two half ring bodies 303 on the two ends of the horizontal section of the pipe body 1 respectively, and at the same time make the two half ring bodies 303 fit on both sides of the vertical section of the pipe body 1 respectively, and finally lock the two half ring bodies 303 together through the locking ring 304, thereby strengthening the corners of the pipe body 1.

[0029] The outer side of the locking ring 304 is uniformly formed with protective patterns;

[0030] This design makes it easy for users to rotate the locking ring 304, making the operation easier.
