IV. question
1．建筑给水系统由哪几部分组成？【答题要点】 --------------------------------------------------------------------------------
Indoor water supply system is usually divided into life, production, fire-fighting.
--------------------------------------------------------------------------------

2. water supply system there are several water supply? conditions under which various used? 【 answer points 】--------------------------------------------------------------------------------
Four, namely direct water-supply mode, set the step-up device water supply, water supply and water supply of the partition and pressure tank water.
Indoor water supply system of water-supply mode is generally based on the following principles to select: ① to meet user requirements, should strive to achieve a water supply system is simple, to reduce the cost and management costs;
② make full use of urban water supply pipe pressure directly, if outdoor water supply network pressure does not meet the whole building water requirements, consider building the underlying use of outdoor water supply pipe pressure directly with pressurized water supply, upper (set booster devices);
③ When two or more with water and water pressure should be as close to theUse of common water supply system. --------------------------------------------------------------------------------

3. current water supply pipeline which common pipe? how to connect the respective? 【 answer points 】--------------------------------------------------------------------------------
The present building water pipe used pipes: plastic, composite pipe, steel pipe, copper pipe, cast iron and stainless steel pipe, etc.
① pipe connection method with thread connection (also called threads), welding and flange connection three connection.
② plastic pipe connection methods are threaded connection, bonding and flange connections, etc. --------------------------------------------------------------------------------

4．常用给水附件的作用各是什么？【答题要点】 --------------------------------------------------------------------------------
Water supply pipeline attachment is installed in the pipeline and equipment on the opening and closing and regulating device. Annex to the General divided into water allocation and control accessories.
Distribution add-on is installed in the sanitary appliances and water points in various taps to regulate and distribution of water. ① water Accessories: ball valve type with faucet, faucet, lavatory with tap-taps and mixer faucet.
② control accessories used to regulate water flow, pressure, flow, switching change in the direction of flow, such as globe valve, gate valve, check valve, ball valve and safety valve, etc. Water supply and drainage engineering common valve according to the body structure and function, can be divided into globe valve, gate valve, butterfly valve, ball valve, plug valve, check valve, etc. --------------------------------------------------------------------------------

5. in accordance with the rules of the water supply piping layout? what are the specific requirements of? 【 answer points 】--------------------------------------------------------------------------------
Indoor water supply pipe pipeline layout principles and specific requirements as described below.
① building water service pipe from the water balance and water supply reliability, should generally be from building water consumption Max Office and does not allow the introduction of broken water Department. When building a comparative health appliances layout should be evenly in the introduction, in the middle of the building to reduce the pipe network to the most negative point of water, reduce the length of pipe head loss.
② indoor water supply piping layout and buildings, buildings, structures, and health equipment and production equipment layout, as well as the water ways and so on. Piping arrangement should strive to achieve the shortest possible length of straight towards, and walls, beams and columns of the parallel laying, both in appearance and to consider the construction maintenance convenience. Water and sewer water should be as close as possible to the largest equipment place or does not allow continuous supply of water to ensure a reliable supply of water, and reduce the flow of pipeline so that the transfer of large diameter pipe length min. Indoor water pipes do not allow laying in drains, flue and air duct, is not allowed to pass through the toilet tank, window, wall, should be avoided as far as possible through the buildings of the settlement joint. If you must go through when to take the appropriate measures. --------------------------------------------------------------------------------
