9 install rubber joints, screw bolts should stretch outer joint valve repair, bolt flange face of each diagonal compression method by repeatedly tightened evenly to prevent pressure side. Wire port connector should use the standard wrench uniform force tighten, do not use the afterburner rod afterburner slide wire to make the union, broken ribs and slippery, but also to periodically check valve manufacturers, in order to avoid causing loose off the plate or seepage. 10 rubber joints under pressure in the initial (eg: installation pressure test, etc.) after long-term disabled or enabled again before the gate should be re-pressurized tighten the bolts again put into operation. 11 use or storage rubber joints, should avoid high temperature, ozone, oil and acid-base environment. Use outdoors or in the pipeline should be built windward sunny shade frame, non-exposure, rain, wind erosion. Joint surface painting and winding insulation materials is strictly prohibited. Due to the existence of the problem of aging of rubber products, should be checked and replaced. Flexible rubber flexible connector products: JGD-type flexible rubber joints JGD-A type flexible rubber joints JXF double ball-type flexible rubber joints JGD dirty filter type flexible rubber joints GJQ (X) -SQ- Type II Three sphere flexible rubber joints GJQ (X) -4Q-II-type four-ball flexible rubber joints KTGJQ (X) -II type adjustable flexible rubber joints JGD-B-type flexible double sphere wire connection rubber joints JGD-A1 type reinforced with Flexing double ball (single ball) JGD-B-type rubber Reducing joint JGD-C type rubber isolator GJQ (X) -KG clamp flexible rubber joints rubber flexible joints is made of fabric reinforced rubber composition and flat-shaped pieces of wood joints, loose metal flange or threaded pipe flanges, pipe isolation for noise reduction, compensation displacement connector. It is a highly flexible, high air tightness, chemical resistance and weather resistance of the pipe joints. Divided by shape: Concentric other tracks, concentric reducer, eccentric reducer. According to the structure is divided into: a single ball, double ball, elbow sphere. Divided by connection type: flanged, threaded, threaded pipe flange connection. Divided by the working pressure: 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa five grades. _ British electromechanical valve outlets (certified) _ valve provided by City Electrical Equipment Co., Ltd. of England.
