Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1: the most basic structure for realizing the functions of the utility model

The utility model provides a special socket seal structure of nodular cast-iron pipe water pressure test, includes cast iron pipe fitting 1, and the right-hand member of cast iron pipe fitting 1 can be dismantled and is connected with closing plate erection column 2, is provided with closing plate 3 between cast iron pipe fitting 1 and the closing plate erection column 2, and closing plate 3 cover is established at the right-hand member of cast iron pipe fitting 1, and the right-hand member face parallel and level of closing plate 3 and the right-hand member face of cast iron pipe fitting 1.

Wherein, the sealing plate 3 is made of 20mm thick nylon material with Rockwell hardness of about 90 plus or minus 5. And processing into a circular plate with a certain outer diameter. The size of the cast pipe is equal to the specification of DN300-DN600, and a phi 100 mounting hole is reserved in the middle. The sealing plate 3 can be suitable for different specifications in daily use, and the use conditions of different specifications do not influence the use effect of other specifications.
