Fire Sprinkler System Design

the design of the sprinkler system a number of important issues - the sprinkler system, automatic fire fighting cons - Fire Industry

Description: from the perspective of design, articulation "automatic sprinkler extinguishing Design Code" (] GB50084-2001) [1 (hereinafter referred to as "spray Rules") and the practice of engineering on design of automatic sprinkler systems Sprinkler Layout hydraulic calculations, fire water tank and pump adapter for the analysis of these issues to explore, expert reviews, peer correction. ?

1, sprinkler heads? rational arrangement of the nozzle is designed sprinkler system security and economic criticism. "Rules Spray more emphasis on the role of the source area of strength and consistency of the jets and the nozzle opening. For each radius of the nozzle, on the one hand, and manufacturers of products and their technology settings, on the other hand, and the location of the dispenser of the third pressure, and location of sand (column lattice and the impact of a variety of obstacles). "Spray Rules "prescribed distance in a" limited "in order to better ensure the strength and uniformity of spray irrigation and open on time. ?

1.1 The principles and requirements of sprinkler heads
(1) the role of the region to meet the water density and uniformity of the spray nozzle of the fast opening (nozzle heating conditions and hours);

(2) within a flexible spray nozzle in the arrangement does not seem to reveal some shortcomings, there is not too big blanket?

(3) ensure that wet the foot of the wall and a range of wall?
(4) between them and not affect the inter-jet;?
(5) according to specifications and practical obstacles to block the agreement, and actively coordinate with the appropriate expertise?

(6) must meet the specifications of the sprinkler heads of other relevant requirements?
(7) When to consider the effects of fire smoke plume on the action of the nozzle;?
(8) associated with the practice, a comprehensive analysis of relevant standards, eating deep quasi-standard in the words given.

1.2 radius and sprinkler heads spray
radius of spray nozzle is the primary database schema, it represents economic value does not occur when the nozzle is not covered by the work of the virgin, there is not too important coverage. With dangerous levels of water density, the nozzle characteristics and work stress. sprinkler heads in engineering design, like architecture, the radius of spray can be flexible square, rectangular or square shaped quadrilaterals. radius of spray nozzle is different from the calculation of the radius, which is the basis for calculating the radius, taking the water density, uniformity of water spraying, warm conditions and nozzle opens in accordance with standards derived values. Specific Table 1: Through the provision of sprinklers more affected by other factors, in fact, it is not often on a fixed nozzle arrangement distance, let alone the same building are not using a remote distribution is the same floor, the same district fires often the case. In addition, as a civil engineering design, decoration design different, need to re-decoration have been replaced, the distance should not be in conformity with the specifications set the maximum distance, but in fact are not easy to achieve the specifications of sprinkler and water spray of uniform intensity. ?

Design must be based on concrete projects, selected according to the design flow water nozzle density coefficient, the pressure of work to identify and examine the heating nozzle v.
