Microelectronic element connecting pipe fitting

Abstract

The invention belongs to the technical field of connecting pipe fittings, and particularly relates to a microelectronic element connecting pipe fitting which comprises a connecting pipe, a connecting nut, a connecting nut sealing gasket and a sealing gasket. The tower drum foundation is a multi-cavity reinforced concrete box foundation composed of a top plate, a bottom plate, a transverse partition wall, a longitudinal partition wall, an inner drum wall and an outer drum wall, a bottom die is arranged on the lower surface of the top plate, each cavity is filled with a ballasting material, and the ballasting material is any one or a mixture of more of sand, plain soil, pebbles, gravels, slag and furnace slag; the stress performance is better, compared with an original independent foundation, the rigidity is improved, the horizontal lateral pressure is increased, horizontal lateral displacement of the foundation is prevented, the use amount of reinforced concrete is reduced, and the manufacturing cost is saved.

Description

technical field [0001] The invention belongs to the technical field of connecting pipe fittings, and particularly relates to a connecting pipe fitting for microelectronic elements. Background technique [0002] At present, the plumbing pipes supplied on the market basically use traditional galvanized pipes and copper pipes, and their connection methods follow the outer wire processed by the pipes. It is very easy to be oxidized and corroded, which affects the actual service life and pollutes the water quality. Aluminum-plastic composite pipes can overcome and reduce water pollution. Although the use of snap connectors can be used for pipe connection, due to oxidation in water And it is easy to corrode the aluminum skin in the middle and lose its strength, causing the aluminum-plastic composite pipe to rupture and leak water, and because the aluminum-plastic composite pipe is prone to thermal expansion and cold contraction, the sealing performance of the snap connection will ...

Problems solved by technology

[0002] At present, the plumbing pipes supplied in the market basically adopt traditional galvanized pipes and copper pipes, and the connection method follows the processing of outer wires in pipes. Regardless of direct joints, elbows, tees and other pipe connectors, all pipes with internal It is very easy to oxidize and corrode, which affects the actual service life and pollutes water quality. Aluminum-plastic composite pipes can overcome and reduce water pollution. Although snap-fit ​​connectors can be used for pipeline connection, due to oxidation in water And it is easy to corrode the aluminum skin in the middle and lose its strength, causing the aluminum-plastic composite pipe to break and cause water leakage, and because the aluminum-plastic composite pipe is easy to be heated and contracted, over time, it affects the sealing of the buckle connector. The resulting water leakage occurs from time to time, which affects the popularization and application of aluminum-plastic composite pipes. Then, the stainless steel-plastic composite pipes are used to replace the above three pipe materials. Parts are bonded together, which involves high bonding process requirements, and the bonding fastness varies from person to person, relatively lacks technical support, and is difficult to be used in occasions with a certain temperature; The method of adding pipe connection pipe fittings for sealing connection, the problem occurs at the expense of the inner diameter of the pipe, and the connection is relatively complicated
