Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the following detailed description of the present invention is made in conjunction with the accompanying drawings and the detailed description, it is to be noted that the features of the embodiments and examples of the present invention may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

As shown in fig. 1 to 4, the corrosion-resistant metal elbow pipe fitting with a uniform wall thickness in this embodiment includes an elbow body 1, a sampling port is provided on a pipe wall of the elbow body 1, a hollow joint 2 is provided at a position corresponding to the sampling port on an outer side of the elbow body 1, and a sampling pipe 3 is installed at the joint 2;

the sampling pipe 3 is matched with the water outlet of the joint 2 in size, a baffle ring 3a is arranged in the middle of the sampling pipe 3, a sealing gasket 4 is sleeved at one end of the sampling pipe 3 connected with the joint 2, and the sealing gasket 4 abuts against the baffle ring 3 a;

keep off ring 3a and be provided with the recess in the position that corresponds sealed 4, sealed 4 places in the recess, the upper end of sealed 4 stretches out in the recess, keep off ring 3a and be provided with a plurality of dentate grooves 3b along the position of recess circumference, dentate groove 3b and recess intercommunication, be provided with groove 2a on the inner wall of joint 2 and the 3 one ends of being connected of sampling pipe, the part that sealed 4 stretches out in the recess of filling up is pegged graft in groove 2a department, groove 2a is cyclic annular, it encircles the cloth along the circumference that connects 2 inner walls.

The upper end of sampling pipe 3 is provided with the external screw thread, connects to be provided with the internal thread in 2, sampling pipe 3 with connect 2 threaded connection.
