FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the SanitaryAppliances and Water Fittings Sectional Committee had been approved by the Civil Engineering DivisionCouncil.

IS 780 was first issued in 1956 and the first, second, third, fourth, fifth and sixth revisions were issued in 1963,1966, 1967, 1969, 1980 and 1984, respectively. In this revision, the committee, following the practices atInternational level decided to merge IS 2906 in this standard.

For connections of sluice valves to a pipeline, certain situations may require the use of fittings like tail piecesand adapters. The requirement of these fittings are covered in IS 1538.

While formulating the Standard an attempt has been made of making this standard in line with other InternationalStandards formulated on the subject. Guidance has been taken from BS, AWWA, DIN, JR3and 1S0 standards.At the same time the practices followed in this field in the country have been kept in view.

The information to be supplied with enquiry and order by the purchaser is given in Annex. D.

The composition of the technical committee responsible for the formulation of this standard is given atAnnex F

For the purpose of deciding whether a particular requirement of this standard is complied with the final value,observed or calculated, expressing the result of a test or analysis shall be rounded off in accordance withIS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.

TESTING OF SLUICE VALVES

B-1 CLOSED-END TEST

B-1.l Each valve shall be tested with the spindle invertical position, unless otherwise specified by thepurchaser, The testing machine, which may be eitherof hydraulic or mechanical type, shall exert adequateforce to compress the flexible material on either sidewithout exerting an undue load on the valve body,

B-1.2 Each valve held in vertical position shall besubjected to three hydrostatic tests. The first testshall be made with the wedge open and the pressureapplied for a period of minimum 5 minutes to thewhole body of the valve after releasing air throughthe gland. The second and third tests shall be madeto determine the water tightness of the faces withthe wedge closed. After the first test, the bodypressure shatl be reduced to working pressure and

the wedge shall be closed so that the bonnet remainsfilled with water. The second test shall be conductedwith the pressure (see 10.1.1) applied to the one faceand the third test with the pressure applied to theother face of the wedge. Under this condition, thevalve seating on the down-stream side shall bewatertight for a period of 2 minutes. During theperiod of above test, the pressure gauge reading shallnot fall below the test pressure.

B-1.3 A typical arrangement for closed-end test forsluice valves is shown in Fig. 7. The first testis donewith the wedge open and the pressure applied to thewhole body of the valve. The second test is made asshown by applying pressure from side 1’hydraulically,the third test is done applying pressure from theside X.

B-2 OPEN-END TEST

B-2.1 Each valve held in vertical position shall besubjected to three separate hydrostatic tests, The firsttest shall be made when the wedge is open and the

pressure applied to whole body of the valve afterreleasing air through the gland and for this test onlyuse of the-testing machine for closed end testing shallbe permissible. The second and third tests shall bemade to determine the water-tightness of the faces withLhewedge closed and the valve fixed at one end only.AIler the test, the wedge shall be closed so that thebonnet remains filled with wa(er. The second test shallbe conducted with the pressure (.~ee10.1.1) applied tothe one face and the third test with the pressure appliedto [he other face of the wedge. Under this condition,the valve seating on the down-stream side shall bewo[ertight for a period of 2 minutes, During the period

of above test, the pressure gauge reading shall-not fallbelow the test pressure.

B-2.2 A typical arrangement for open-end of sluicevalve is shown in Fig. 8. The first test is conductedwhen the gate is open as in the case of closed-end test,the second test is conducted by applying the pressurefrom the side Y, the third is performed by reversingvalve and applying pressure from the side X.

NOTE — Any valve that has been tested only by ihe closed-endtests and which, during the testing of a main or part of main afterlaying, occupies a terminal position on the main, should have itsexposed end blanked off and its wedge in the open position. Anyvalve that has been tested by the open-end tests should be simi-larly treated if the test pressure applied to the main exceeds themaximum working pressure. In either case any precaution neces-sary to resist hydraulic thrust on the valves by strutting or other-wise should be taken.
