into W no socket coupling connection, type A flexible flange connection. 1) type A flexible flange connection The socket and mud on the surface of the flange gland work cleaning to clean. Mural out outside the pin positioning line. In set with the socket flange gland, rubber ring, aprons edge alignment and positioning line. To advance in the socket socket end, keep the axis of the inserted into the pipe and socket in a straight line. For flange hole tighten bolts, three ears gland three Angle bolts to tighten them one by one; Four ears gland bolts, by diagonal position should tighten in turn. 2) W socket coupling connection Installation should be according to the required length, the straight pipe fixed and firm, with a grinding wheel cutting machine disconnect, cross section should be vertical and smooth, no flash, burr, lest hurt rubber sealing ring. Use the screwdriver to loosen the clamp bolt, take out the rubber ring, clamp set into the bottom line. Rubber trap into the lower pipe end, insert the upper pipe, rubber ring, so that two interfaces is flat and level for good. The clamp set into the rubber ring. With screwdriver lock clamp bolts so tight belt fastened in place, prevent excessive tension, bolt slippage. 6.6 the drainage pipeline construction points for attention (1) pipeline laying good, will be reserved nozzle mount temporary tube wall, to prevent clogging up sundry fall into tube. (2) pipe inside and outside surface should be smooth, no bubbles, cracks, uniform wall thickness, colour and lustre is consistent. Vertical section deflection is not greater than 1%. Pipe should be rules, smooth, without burr. Socket should have a pin, and form a complete set of pins. (3) to self-inspection of piping installation, after confirmed from the reserved do closed water test tube mouth water, water height should be not less than the underlying sanitary ware on edge or the height of the underlying, filled with water for 15 minutes after the water drop, 5 minutes to fill up observation, the surface is not falling, the interface and pipeline without leakage; Building storm sewer should make water test, the water height must achieve each riser upper rainwater head, irrigation experiment lasted 1 hour, each interface and pipe is not leak. Irrigation experiment by the relevant personnel to inspect, and fill the concealed engineering acceptance record, concealed engineering acceptance formalities. , crane main drain in condole top, need to separate do before condole top closed closed water test. (4) the main drainage riser and horizontal main pipe, all should do ball test, pass the ball the ball diameter not less than two-thirds of drainage pipe diameter, pass the ball rate must reach 100%. (2) sanitary ware installation (1) process: Installation readiness to sanitary ware and parts inspection, sanitary ware installation and sanitary ware accessories pre-loaded to sanitary ware steady loading, sanitary ware, ground and wall crack treatment - sanitary ware appearance inspection - water test; (2) the pipeline to jilt mouth should guarantee the installation elevation, coordinates, size accurate, the waterproof and decorate before the check in time. Sanitary ware in steady should be done before loading inspection and cleaning. Of the specifications of the sanitary ware, model must comply with the design requirements, and have the factory product certificate. Sanitary ware appearance should rule, geometric modelling, the surface is smooth, beautiful, no crack, edge smooth, tonal and consistent. Sanitary ware parts specifications should be standard, the quality should be reliable, surface smooth, uniform plating, clear thread lock is moderately elastic, no sand holes, cracks and other defects. Cistern fittings should adopt water-saving sanitary ware. Sanitary ware installation requirements interface closely, no leakage, coordinates and elevation is correct, all kinds of accessories, bolts, expansion bolts must be chrome plated and galvanized fasteners, sanitary ware and nuts and metope then point should be rubber MATS, prevent sanitary ware fracture. Sanitary ware, it is, straight and firm performance is good, no loose phenomenon. All kinds of valves and chrome plated parts should be intact, open and flexible, tightly without leakage. Basin, washing basin drainage bolt should have the overflow mouth, of the overflow mouth direction should be sanitary ware weir. All kinds of sanitary ware, fittings shall have certificate archiving, sanitary ware accessories should adopt water-saving water. Before completion, water test should be done, sanitary ware and accessories should be scrubbed clean. If the ground installation putty caulking should be adopted. (3) the lavatory installation 1) the lavatory parts installation: A. install basin drains: buccal mother root, the rim of the eye, the first rubber pad, insert the mat mat after good putty on the basin drain hole, the weir in the drains should aim at basin drain weir in the eye. Outside with good putty rubber mat, set on the rim of the eye, take root mother, again with homemade wrench stuck drain cross bar, with flat wrench on the mother to moderately elastic. B. install washbasin faucets: first lock water mouth mother, mother, in good water mouth root mat putty, insert the washbasin water hole, combined with rubber mat under the rim of the eye, take root mother left hand holding the water mouth, right hand with homemade eight solid wrench will lock the mother to elastic moderately tight. 2) sinks steadily with: A. lavatory bracket installation: should be in accordance with the drainpipe center draw vertical lines on the wall, from the ground up measure the height of the regulations, draw a horizontal line, according to the basin wide draw the bracket position reticle on the horizon. According to mark 30 x 120 mm holes carved into phi. Will wash basin stents planted her leveling. Then wash basin in the leveling and alignment on a support. Will rack hook hook under the basin fixed hole, tighten the basin of the fixed bolt, leveling is. B. Cast iron frame lavatory installation: according to the above method to find good reticle, according to mark 15 x 70 mm holes carved into phi, planted good lead scrolls, using 2 1/2 screws to pot rack fixed on the wall. Pull the adjustable shelf fixed bolt loosening, activity will hook in the basin under a fixed hole, tighten the basin of the fixed bolt, leveling and alignment. 3) the lavatory drain connections: A.S type trap connections: should drain thread in the wash basin bottom tu lead, tie up a little linen yarn. Will trap last twist on the port, elastic moderate. Then trap section under the lower bound of the oil packing line inserted within the drainpipe, the rubber gasket on the joint of trap, lock the mother hand tight after straightening alignment. Using a wrench screw to moderately elastic. With putty will drain plug tightly, erased. P. type trap connections: should drain thread in the wash basin bottom tu lead, tie up a little linen yarn. Set the trap section on the port, elastic moderate. Then trap horizontal section length as required to match well. Lock and protect mouth tray sets of back-to-back on the cross section, in the end cover oil packing rope, try Ann height is appropriate, such as inappropriate vertical section adjustment are available, and then put rubber pad lock, lock the mother tur
