A device and method for dynamically sealing between rotatable members such as a rolling cone of a rock bit. The assembly includes a seal ring having a facing surface of a relatively hard material, such as hardened steel or tungsten carbide, and a second seal ring of a softer material, the softer material being harder, however, than typical elastomers. Suitable materials for the relatively soft seal ring include tin, copper, aluminum, magnesium, lead and alloys thereof, as well as non-metallic materials such as nylon-zytel, acetal, and polypropylene. The relatively soft seal ring may be affixed to a third seal ring or maybe affixed directly to the cone steel, for example. The seal assembly provides potential for longer life relative to elastomeric seals and requires less axial space along the journal surfaces than certain conventional metal seal assemblies.

The invention discloses an electrical socket of an electric heating bag, which comprises a socket coupler (4), a soft isolation piece (2) and wires. The electrical socket is characterized by also comprising a plugging structural piece (8) and a fixing piece (1). The fixing piece (1) made of a hard material is in buckling connection with the soft isolation piece (2), wherein the buckling connection is realized through holes (12) and buckles (3). The socket coupler (4) is mechanically connected with the fixing piece (1). The fixing piece (1) is arranged between the socket coupler (4) and the soft isolation piece (2). The fixing piece is hard at an ordinary state so as to realize the mechanical connection of the socket coupler and the electrical socket and protect components in the electrical socket. Due to the adoption of the structure of the fixing piece (1) or the buckle edge (17), and the special structure of the soft isolation piece (2) and the buckle fin (18), the fixing piece (1) and the soft isolation piece (2) are connected reliably and firmly. The liquid leakage problem of a gap between a dry-wet soft interface opening (7) and a wire (6) is solved due to the adoption of the plugging structural piece (8).

The present invention provides a preparation method of gradate nanostructure transition metal oxide by a two phase solvent soft interface method which comprises the steps of that: metal salt or metal oxide is added into water, and the pH value of the solution is adjusted by acid or base, then the corresponding reactant precursor is obtained; another water insoluble organic solvent is added into the solution, and the whole mixture is subjected to solvothermal treatment, and then the solid product is obtained by pumping filter, finally, the corresponding gradate nanostructure transition metal oxide is obtained after scrubbing and drying. The transition metal oxide of the present invention has excellent gradate structure, for example, titanium dioxide has a main structure of micron order spheroidal particle which is formed by the ordered array of a plurality of nanorods. The titanium dioxide of the present invention has a high visible light photocatalysis activity, a simple synthetic route, an easy technology, available raw material, low cost and high yield, and is adapted to mass production.

The invention relates to a tungsten / transition layer / steel composite material and a low-temperature and low-pressure active diffusion connection preparation method thereof, and belongs to the technical field of preparation of composite materials. Raw materials used for preparing the tungsten / transition layer / steel composite material comprise a tungsten substrate, an active metal Ti layer, a soft interface layer and a steel substrate. The method comprises the following steps: welding the soft interface layer and the steel substrate through a traditional welding process, sequentially superposing the obtained layer to the active metal Ti layer and the tungsten substrate, and carrying out vacuum diffusion connection to prepare a tungsten substrate / titanium layer / soft interface layer / steel substrate connecting piece which is the high-performance tungsten / steel composite material. The tensile strength of the composite material is greater than or equal to 386MPa. The composite material has a reasonably designed structure, and the problems of large joint residual stress, low strength and high requirements of welding conditions of present tungsten / steel connecting pieces are solved through matching of the structure with the method. The preparation method is simple, and is convenient for industrial application.
