Unlcss ot hewisc specified herein, all equipment, material, and articles incorporated in the products covcrcd by this specification shall be new and may be fabricated using materials produced from rccovered materials to the maximum extent practicable with
35、out jeopardizing the intended use. The term “recovered materials” means materials which have been collected or recovered from solid waste and reprocessed to become a source of raw materials, as opposed to virgin raw materials. None of the above shall be interpreted to mean that the use of used or re
36、built products is allowed under this specification unless otherwise specifically specified. 3.4 Component parts. Table I lists the general component parts and their application to the valves covered in this specification. The parts application is intended for guidance only; however, when parts liste
37、d are incorporated in the valve construction, materials of such parts shall be as specified. This general guidance shall not relieve the contractor from delivering valves that meet the specified requirements of this document. 3.5 Construction. Control valves shall be constructed for use with seawate
38、r. Functional construction characteristics for type I, class 1 through 6, and type II valves shall be as specified in 3.5.1 through 3.5.3 (see 6.3). Weight and size of the assembled valves shall be kept to a minimum. 3.5.1 Design pressure. Control valves shall be constructed for an internal operatin
39、g pressure of 250 lb/in2 and shall withstand an internal test pressure as specified in 4.6.3. The bonnet, dome, cover, or distributor portion of the valve shall be constructed to withstand the highest control pressure to which it will be subjected in the specified working range. 3.5.2 Type I. Contro
40、l valves of the type I classification shall be constructed for hydraulic operation. The movement of the valve disc shall be positively actuated by hydraulic pressure upon the diaphragm when subjected to a minimum fluid pressure of 40 lb/in2 while controlling fluids in a range of 40 to 250 Ib/in2. Di
41、aphragms shall not be employed as a disc or seating element. Control valves shall be constructed so that failure of the diaphragm will cause the valve to remain closed and shall seat with line pressure. Control valves shall be of the globe pattern construction in which all moving parts shall be guid
42、ed. Type I valve construction shall be as specified (see 3.6 through 3.6.16). 3.5.2.1 Class 1. Sprinkler supply valves shall be constructed to be held in the closed position by a combined force of valve spring and inlet firemain supply pressure acting on the valve disc. The valves shall be construct
43、ed to open rapidly when actuated by hydraulic pressure and close rapidly when hydraulic pressure is released. These valves shall permit control of seawater flow to the systems sprinkler head valves. Class 1 valves shall be constructed with an atmospheric vent, a valve position indicator, a test fitt
44、ing, and a manual actuation mechanism. 3.5.2.2 Class 2. The remote control valve shall be constructed to be held in the closed position by an internal valve spring when the control system piping is not pressurized. The valve shall be constructed to open fully and close completely when actuated by hy
45、draulic pressure. This valve shall permit securing of the sprinkler supply valve from an operation station other than the one from which actuation occurred. 8 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-flIL-V-L750/F ri 999990b OY577bY 9 D M IL-V
46、- I 7501 F(SH) I 3.5.23 Class 3 The spring-loaded lift check valve shall be constructed to be held in the closed position by an internal valve spring when the control system piping is not pressurized. The valve shall be constructed to open fully and establish flow through the valve when hydraulic pr
47、essure is applied to the inlet side of the valve. The valve shall close completely when hydraulic pressure is applied in the reverse direction through the outlet side of the valve. This valve shall permit thecontrol system to be operated from more than one operating station by preventing reverse flo
48、w. 3.5.2.4 Class 4. The hydraulic operated check valve shall be constructed to be held in the closed position by an internal valve spring. The valve shall open fully when hydraulic pressure is applied to the valve through an actuation connection and close completely when pressure is relieved. This v
49、alve shall provide the means for venting the hydraulic pressure from the sprinkler supply valve, thereby permitting the sprinkler supply valve to close. 3.5.2.5 Class 5. The hydraulic operated control valve shall be constructed to be held in the closed position by an internal valve spring when the control system piping is not pressurized. The valve shall open fully when hydraulic pressure is applied to the valve through an
