Ventilation pipes are mainly used in industrial and architectural engineering, and the application fields are mainly involved in the cleaning system of the dust free factory building in the electronic industry.
Purification system of medicine and food aseptic workshop, hotels, hospitals, shopping malls and office buildings factory of central air-conditioning system, dust, smoke, oil and exhaust pipe, or post industrial environment with comfortable air supply pipe and gas drainage system, gas pumping for coal mine environment control air supply system and so on industrial pollution control;
1) for complex civil buildings, at the design stage, all kinds of work (HVAC, water supply and drainage, power supply lighting and Architecture) should first negotiate the space separation and determine the elevation range of each pipeline. The general case not set himself beyond the boundaries. In case there is a separate section to cross the boundary, it should be negotiated with other engineering of the ventilation pipe.
2) to solve all kinds of ventilation pipe collision and coordination principle, generally: "let the pressure get tubular bassoon, no pressure". For example, the water pipe and the wind pipe collide, then the tap water pipe should be turned. The cold and hot water pipes and water pipes together, should change the cold and hot water pipe.
3) before the construction, the engineer of the equipment general pipe will draw the lines of each type of work and draw the single line on a flat map. Each type of pipe is used with a color pen. In each point of the intersection of its elevation, see if there is any contradiction, timely discovery, the problem is solved before the installation.
4) in order to reduce investment, save space and reduce storey height, some laying pipes without slope requirements can be laid on beams (such as water pipes, fire sprinkler pipes, etc.).
