Pneumatic ball valve construction schemes and note 4)

first of all, please note that before construction, in the depth of the buried gas construction in accordance with the relevant provisions, if buried in more than construction requirements, you must use a protection tube. , after the first stone mining, gravel and other debris cleared, and then spread about cm thick sand well pressure. And the connection pipe, pneumatic valve, to make them after the construction of the end of the horizontal and vertical state. And other underground objects should keep distance buried: (1) above the surface features of regional heating ℃, such as pyrazole soft than the distance of the star, such as using the maintenance cm above the protective measures. (2) water pipe, electrical installation materials, communication cable, centimeters of above. (3) : underwater centimeters of above. Secondly, should use note: butt welding pneumatic ball valve, ball: confirm the installation position of the ground water or damp, change the installation location, or water or wet wipe out, to ensure that the site does not sink, must at this time and then pipe the basis of strong pressure adjustment ground into a horizontal position. , one end is fixed in the first pipe welding machine, pneumatic valve opened the package, one end fixed on the ball, if the fixed length welding machine is not enough, can't use two fixed fixed ball machine, pneumatic ball valve is transferred to the same height at the other end of the fixed unit. - - - - the heating plate surface treatment heat to maintain pressure welding joint fixed installation - cooling - - welding machine. , the other end of the pipe, through welding fixed after welding. Note: when the arrow on the operating system side of the identity of the pneumatic valve must be consistent with the airflow; , welding operation, to prevent the inside of the pneumatic valve block in bags of different materials used; The vertical welding tube and pneumatic valve level; , about a minute after welding machine, cooling of the separation; , T pneumatic ball valve handle removed from the case, after assembly, then put his hand in the knob fully inserted. Note: use the 'T' type pneumatic valve handle switch state to test; , confirm whether switching pneumatic valve, pneumatic ball valve pneumatic valve connectors must indicate the length of the PE pipe and line direction ( - ） At this time is open. Vertical line markers ( ‖） Closed at this time. Closed ( Closed) : in open adapter ° clockwise. Open ( Open) : in the closed state adapter ° counterclockwise direction. Gear box TOP adapter? ° or so, the arrow ° switch completely shut down ( Seated) And completely open state, Full open) Countries cannot drive to open or close. Pneumatic valve leakage test, USES the elution; The use of laying around, the ball knob of sand. Third, the use of fusion socket, the position of the ball, confirm the installation: groundwater or damp, change the installation location or water or wet area, in order to ensure construction land not sinking. Foundation must be adjusted, to control the position of the level with the ground at this time of intense pressure. , pipe: check whether to cut off the right angles of minors should be rectangular pipe cutting. , scraping the pneumatic ball valve and pipe surface: surface of pneumatic valves and pipe fittings on the surface of the connecting pipe, insert about % website connecting pipe length of the label, the label must be completely mature, for. Mm, wall thickness, after the completion of surface scratch the deleted package sleeve, tube inserted into the connecting pipe completely. （ Move. Connected to the pipe plug insert) Note: scraper is used to connect the surface of the most important work, so the tube surface is shaven.
