A cast-iron slide gate is a cast-iron or cast-ductile-iron, vertically sliding gate with metal (usually bronze or stainless-steel) s

27、eating faces and adjustable metal (usually bronze or stainless-steel) wedges. The slide gate consists of a self-contained frame or nonself-contained frame and a slide. Examples of where this type of gate is used include the control of water and wastewater through orifice openings in walls, at the en

28、ds of pipes, at the ends of open-top channels, or within open-top channels and controlling flow at openings in tank walls. Downward-opening gates act as weir gates. Slide gates are raised and lowered by means of a stem or rod using a manually operated screw stem actuator, an electrically driven scre

29、w stem actuator, or by a hydraulic or pneumatic cylinder. Gates are mounted directly to concrete walls with anchor bolts and leveling grout, or grouted into blockouts within concrete channel walls, or bolted to a pipe flange or wall thimble. Other terms used to describe slide gates include penstocks

30、 and sluice gates. The term slide gate has been adopted for use by this series of standards, which supersede ANSI/AWWA C501-92.

31、ide Gates The slide gates represented by ANSI/AWWA C560 through ANSI/AWWA C563 differ in material and means of sealing between the slide and the fixed frame as described below. ANSI/AWWA C560 gates have a cast-iron or cast-ductile-iron slide and frame with machined metal seating faces and wedges to

32、force the slide to seal between the seating faces on the slide and frame. ANSI/AWWA C561 gates have a fabricated, reinforced stainless-steel slide and frame with ultra high molecular weight (UHMW) polyethylene seating faces and seals or UHMW polyethylene seating faces and resilient rubber seals. * A

ANSI/AWWA C563 gates have fiberglass reinforced composite-plastic or rigid compressed plastic slides and frames of either fiberglass reinforced composite plastic, stainless steel, or coated carbon steel, with UHMW polyethylene seating faces and r

The tentative standard was revised and approved on June 4, 1967, as AWWA C501. Subsequent editions were approv

36、ed in January 1980, June 1987, and June 1992. Following the latest revision, the Standards Council authorized the development of additional standards for slide gates to recognize the widespread use of slide gates similar to ANSI/AWWA C501 gates in performance but manufactured by different methods an

37、d of different materials. For consistency among the new standards and recognizing the new designs employed, the Standards Council directed that each of the standards use the name slide gate in lieu of the term sluice gate. The Standards Council also directed that ANSI/AWWA C501 be redesignated ANSI/

38、AWWA C560, with subsequent slide gate standards numbered consecutively. Subsequent revisions of the standard were approved as ANSI/AWWA C560 on June 11, 2000, and on June 24, 2007. This edition was approved on Jan. 19, 2014. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA

39、) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium included the American Water Works Associ

40、ation Research Foundation (AwwaRF, now Water Research Foundation*) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to regulate

41、 products for use in, or in contact with, drinking water rests with individual states. Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health * Water Research Foundation, 6666 W. Quincy Avenue, Denver, CO 80235. Persons outside the Un

42、ited States should contact the appropriate authority having jurisdiction. Copyright 2014 American Water Works Association. All Rights Reserved. ix effects of products and drinking water additives from such products, state and local agencies may use various references, including 1. An advisory progra

43、m formerly administered by USEPA, Office of Drinking Water, discontinued on Apr. 7, 1990. 2. Specific policies of the state or local agency. 3. Two standards developed under the direction of NSF,* NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System C

44、omponentsHealth Effects. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. I

45、ndividual states or local agencies have authority to accept or accredit certification organizations within their jurisdiction. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does not st

46、ipulate a maximum allowable level (MAL) of a contaminant for substances not regulated by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carci

47、nogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANSI/AWWA C560 does not address additives requirements. Thus, users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements, i

48、ncluding applicable standards. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. During the revision of this standard the issue of critica

49、l buckling of the gate stem was discussed. This resulted in the design load stipulated in 4.4.11.2 changing from the rated output to the extreme output of the actuator. The intent of this was to prevent stem failure. However, it is common to provide gates with actuators sized for modulating conditions and those actuators have higher-powered * NSF International, 789 N. Dixboro Road, Ann Arbor, MI 48105.
