Pneumatic valve installation requirements repair and assemble

pneumatic valve installation requirements, pneumatic valve should be conducive to safety, security, and is conducive to the operation of the pneumatic valve, repair and assemble. The installation of the pneumatic valve, first of all require installation personnel can know to recognize pipeline installation drawing, according to the figure construction of general pneumatic valve installation position and direction of the improvement can dispose ability. Pneumatic valve installation, pneumatic valve operating mechanism from the most appropriate in operation. M ( With operations are the chest. When the center of the pneumatic valve and the handwheel from the ground operation. M, pneumatic operation more pneumatic valve and safety valve set operation platform. More pipe pneumatic valve, pneumatic valve should be focused on the platform, in order to operate. For more than. M and often do not operate a single pneumatic valve, can adopt sprocket, extension rod, activity platform and ladder and other facilities. When the pneumatic valve installed in the operating under the surface, should be set extension rod. Pneumatic valve should be set well, to be on the safe side, should be sealed well. Horizontal pipe pneumatic valve pneumatic valve stem vertically up best, unfavorable install pneumatic valve lever down. Pneumatic valve lever downward installation inconvenient operation, maintenance inconvenience, pneumatic valve, also easy to corrosion accidents. Pneumatic valve is installed base of landing to avoid operating at odds. Side by side on the pipeline pneumatic valves shall have the operation, maintenance, folding space, the clear distance between the handwheel small mm; If tube is apart from the narrow, pneumatic valve should be staggered out on the table. To open the great strength, low strength, brittleness and heavy weight of the pneumatic valve, pneumatic valve installation to set up the frame, supporting pneumatic valve, reduce stress. When installation, on the main branch of derivation on the pneumatic valve should be day close to the manifold. Decompression of the pneumatic valve installation should not be close to the vulnerable to shocks, should be set up around the small vibration, spacious place, in order to maintenance. At the same time, the reduced pressure pneumatic valve should be installed in horizontal pipe runs commonly, installation method and requirements shall be stipulated in the product manual. Bellows type pressure pneumatic valve used for steam, corrugated pipe down installation; Pneumatic valve reverse installation for air. Brake pneumatic valve is the structure of the double ram, shall be installed upright, namely, pneumatic valve stem in a vertical position, hand wheel, handle on it. The structure of a single ram and can be installed at any Angle, but are not allowed to flip. With pneumatic transmission device of gate valve, such as gear, worm gear, electric, pneumatic, hydraulic pneumatic brake valve shall be installed according to the instruction manual and general pneumatic valve stem vertical installation as well. Stop pneumatic valve, throttle valve can be installed in the equipment or pipeline at any position, belt transmission device shall be installed as stipulated in the product manual. By the pneumatic valve pneumatic valve rod shall be for the installation of good days and the vertical. Pneumatic valve for throttling to often operate, regulate traffic, reason should be installed in a spacious place. Aerodynamic lift check valve can only be installed in horizontal pipe runs with the axis of the pneumatic valve disc should be vertical installation; Spring vertical and swing check pneumatic valve can be installed in horizontal pipe runs, also can be installed on the riser of medium flows from bottom to top. Swing the pendulum rod pin when installation should keep horizontal position. Pneumatic valve and pneumatic diaphragm pneumatic ball valve, butterfly valve can be installed on the equipment and pipeline at any position, but with transmission device should be installed upright, which drive the vertical position. When installation should be considered good operation and maintenance. Pneumatic three-way ball valve should be installed vertically. Cock pneumatic valve can be installed at any position, but should be good to watch groove and convenient operation. Three-way or four-way cock pneumatic valve is suitable for vertical or less than the degree of the installation. Security pneumatic valve lever or spring type, should be installed vertically, pneumatic valve rod and the water should maintain good verticality. The export of security pneumatic valve should avoid a back pressure phenomenon, such as exports have a drain pipe, should not be less than the export of the pneumatic valve size. Steam hydrophobic pneumatic valve installed in horizontal pipe runs commonly, disc type can also be installed in the other direction. Pneumatic valve steam traps specific installation method shall be in accordance with the regulations on the use of the instructions. Pneumatic valves are normally installed steam traps or lows at the end of the saturated steam pipe, with the end of the heat pipe steam low; No steam flow often dead end, but it is low; Decompression of the steam system of pneumatic valve and regulating pneumatic valve before the position; And steam heating equipment such as the lower water separator, and the need to frequently hydrophobic
