About press fittings

The Pipe Fittings is a tube connected to a conduit part. Depending on the connection method can be divided into socket type fittings, threaded pipe fittings, flanges and welded pipe fittings four categories. Multi-tube made of the same material. There elbows (elbows), flanges, tees, crosses tube (Phillips) and diameter pipe (size of the head) and so on. Place for pipe elbow turn; flange for tube and pipe interconnected parts, connected to the pipe end, tee pipe together for three places; Stone pipes tubes together for four places; different two tubes of different diameters diameter pipe connected to the place.

Press fittings elongate wire assembly, comprising: at least two elongated, generally flat layered on the wire, said wire having respective, adjacent to each longitudinal edge; conductors disposed in said two layered electrically insulating material layer; and a plurality of press fittings contacts, the wire from the adjacent longitudinal edges of the layered and distributed along the longitudinal extending edges of the respective press fittings insertion of the contact - receiving area. Electronic devices in the high temperature environment under the car in the press fittings engagement of the assembled circuit board. So that the through-hole press fittings terminal of the press-fitting of the peak stress occurs in the substrate does not exceed the design reference value, suppressing the occurrence of damage in the substrate. Integrally formed with the body portion, the pressure holding portions, the distal end portion of the introduction portion and the mating terminal, the cross-sectional area smaller than the sectional area of the introduction section of the holding portion, the elastic force than the elastic force of the introduction portion of the holding portion weakened, reducing little stress on the substrate. In the wiring substrate, the elastic material is filled in connection with the sheet-like substrate, a resin substrate, the stress relaxation occurs in the substrate itself. Along the floor for the printed circuit board or the press fittings the distribution bus comprises a plurality of planar electrically conductive busbar conductor material. Each of said bus conductor through a layer of electrically insulating material separated from the adjacent bus bar conductor. Press fitting a plurality of conductive leads extending from an edge of each bus wire. When the inner conductor and the hierarchical bus is filled with the insulating material into the housing of the cured epoxy resin, an epoxy resin is press-fitted from the surface of the protruding wire. These projections can be press fittings into the lead plate or printed circuit board for supplying power to the backplane or printed circuit board.

About brass faucet maintenance

Division means progress, from this point on the faucet increasingly refined classification can also be seen. Past that single tap has not meet all the requirements of people currently on the market can be divided into the faucet bathtub faucet, basin faucet, kitchen faucet categories. Kitchen faucet manufacturer generally use copper as the material of the faucet. Copper is an essential trace element in the human body, it is an important component of proteins and enzymes in the body. Whether it is grease, bacteria, viruses, oxygen and ultraviolet rays and other harmful qualities can not pass through it and polluted water quality! With brass on human health can play a positive role. Because of its unique tap water can kill 99 percent of bacteria, even if the water burst, causing foreign objects into the bacterial infection, do not worry; good metal cutting performance, reduce production costs make it necessary for every household brass faucet. After selecting a faucet if improper maintenance will affect its life. This is the most difficult thing many people. In fact, this is not difficult, as long as the installation, use, maintenance, proper well, the actual life of brass faucets can be extended, and can remain bright as new.

1. experienced and qualified professionals to install installation, taps should try not to bump with a hard object, not to cement, glue residues on the surface, so as not to damage the surface gloss coating. If you are new housing, water supply network is newly paved, the water will certainly be sand and other impurities before the installation should pay attention to the pipeline debris removal, turn on the water until the water becomes clear for a long time to install the faucet.
 2 big does not necessarily shut off serious effort many people are accustomed to deliberately run out of the faucet so that some force faucet shut tight some, this is very undesirable. This not only does not prevent leaks, but it will seal valve damage, leading to lax leading off.
 3 good habits to ensure complete as new to avoid rust, usually after use should wipe clean the faucet surface; again leading generally more prominent, so be careful not to bump or pressure to it when handling the items.
 4 smaller water to clear impurities in the case of pressure of not less than 0.02mpa, if found to reduce the amount of water, there may be a leader inside clogged. The solution is to use a wrench at the outlet of the faucet spout gently unscrew the screen cover, and then carefully clean the impurities installed, can usually be restored as ever
