4.13 WHEN USINGSIE TESTERSFOR HYDROSTATIC AND PNEUMATIC TESTS, USE TABLENo 9 IN ORDER TO SELECT THE LEVER POSITION (CLAMPING FORCE) ACCORDING TO THE VALVE MEASUREMENT AND PRESSURE.
压力管道，测试椅，实验装置，链接盘和检测设备等都必须符合规定。压力表需在表10所述范围之内。
4.5 ALL VALVES SHOULD BE TESTEDANDEVERY VALVE SHOULD BE SUBMITTED TO THE TESTS INDICATED BY THIS SPECIFICATION UNLESS OTHERWISE SPECIFIEDBY THE PRODUCT ENGINEERING DEPARTMENT OR SPECIFIC CUSTOMER REQUIREMENTS.
所有阀门需依照规范要求或订单要求提交检验。

TITLE: PRESSURE TEST SPECIFICATION FOR CAST STEEL VALVES
标题：铸钢阀门的压力测试规范
1.0 OBJECTIVE目的:
THE OBJECTIVE OF THIS SPECIFICATION IS TO PRESENT THE MINIMUMTESTREQUIREMENTSFOR CAST STEEL VALVES.
用于水压测试的水需含有防锈剂，每公升水需含有7-8克的防锈剂。水中铁锈的浓度不得大于水中防锈剂的浓度，水中的防锈剂—铁锈比例需每周检测一次。
4.9.2 CONTROL THE HALOGEN CONTENT TO THE FOLLOWING AMOUNT:
控制以下元素的总含量：
CHLORINE30.00 P.P.M. MAXIMUM
所有阀门都必须经过测试且所有阀门都必须根据此规范提交测试，除非有相关的产品工程部门的说明或客户明确的要求方可免除测试。
4.6 THE VALVES BEING INSPECTED MUSTBE SUBMITTED TO THE TESTS INDICATED BY THIS SPECIFICATION, RESPECTING THE ORDER INDICATED.
阀门必须进行一个压力释放操作测试以确保所有阀门从完全开启到完全关闭状态时能充分的运作，反之亦然。
(C) 4.3THE FORCE THAT SHOULD BE APPLIED IN ORDER TO COMPLETELY OPENORCLOSE THE VALVE HAS TO BE OF A PERSON UNDER NORMAL CONDITIONS.
阀门内部的气阀应在增加液压之前打开，试压时阀门两端必须很好的密封，这样可避免掩盖阀门壳体，中道，阀杆填料或阀座的泄漏。
4.11 THE VALVES SEATS SHOULD BE CLEAN AND FREE FROM ANY AGENT(GREASE, OIL) THAT COULD ACT AS A SEALANT.IN ORDER TO PREVENT DAMAGE OR SCRATCHES ON THE SEATS, A THIN FILM OF LUBRICANT NO HEAVIER THANTRANSPARENTKEROSENE OR PETROLEUM FILTERED WITH A 4 OR 4.5 MICRON MESH MAY BE APPLIED.

(GATE, PLUG,BALL AND CHECK VALVES)
适用柴油–将清洁的法兰绒织物浸湿并擦拭阀瓣和阀座圈，不允许喷洒、滴入或直接用手来擦拭。
4.12 VALVE POSITIONDURING TESTING阀门在试压时的位置
(C)4.12.1 TEST IN HORIZONTAL POSITION FOR PNEUMATIC TESTINGAND
闸阀的气压测试时阀门应为水平位置，水压测试时阀门位置应为水平或垂直。
所有上密封衬套和阀体阀座圈在装配前都必须做液体渗透测试（着色）。
4.2 THE VALVES SHOULD HAVE A PRESSURE-FREE OPERATION TEST IN ORDER TO MAKE SURE THAT THEY OPERATE ADEQUATELY, FROM COMPLETELY OPEN TO COMPLETELY CLOSED ANDVICEVERSA.
阀门阀座必须清洁无油。为防止阀座被破坏或刮伤，可涂上一层比透明柴油更轻的很薄的油脂膜，或者使用A4或4.5目的石油过滤网。
4.11.1KEROSENE APPLICATION – DAMPEN A CLEAN FLANNEL CLOTH AND WIPE IT OVER THE DISC AND RING SEATS, BLASTING, DRIPPING OR DIRECT APPLICATION WITH THE HAND ARE NOT PERMITTED.
CONTAINS THE PRODUCT ACCEPTANCE OUTLINES, SO THAT THE VALVES APPROVED UNDER THIS SPECIFICATION COVER THE REQUIREMENTS REQUESTED FORTHE FOLLOWING STANDARDS:
规范中规定的每一次不同的试压方式都要进行阀门检验，且遵照相应的表格内容和
试压范围。
4.9 WATER TEST REQUIREMENTS水压测试要求
4.9.1THE TEST WATER SHOULD CONTAIN AN INAX (PROVIDER: TURCO ANDDESCALSY)RUST INHIBITOR OR EQUIVALENT.THE TEST WATER SHOULD HAVE A PROPORTION OF 7 TO 8 GRAMS OF RUST INHIBITOR PER LITER OF WATER.THE RUST VISCOSITY OF THE WATER INHIBITOR COMBINATION SHOULD NOT BE GREATER THAN THE WATER VISCOSITY. THE WATER INHIBITOR-RUST PROPORTION SHOULD BE INSPECTED EACH WEEK.
此规范的目的在于介绍铸钢阀门的最小压力测试要求。
2.0 SCOPE范围:
THIS SPECIFICATION IS APPLICABLE TO THE FOLLOWING VALVES:
此规范使用于下列阀门:
2.1 WEDGE GATE楔式闸阀
1.1.1.- BOLTEDBONNET栓接阀盖
1.1.2.- PRESSURE SEAL压力自密封
测试必须在室温下进行以确保试压液体温度不超过52 °C (125°F).
4.9.4 CLEANING: THE TEST WATER SHOULD BE FREE FROM WASTE OR EXTRANEOUS AGENTS THAT COULD DAMAGE THE VALVE SEALANT AREAS.
清洁：试压液体不应含有废弃物或其它外来物质，以防止其破坏阀门密封面。
4.10 THE AIR TRAPPED INSIDE THE VALVE SHOULD BE LET OUT BEFORE INCREASING THE HYDROSTATIC PRESSURE.THEVALVEENDS SHOULD BE WELL-SEALED SO THAT LEAKS IN THE TEST ASSEMBLYDO NOT HIDE LEAKS IN THE VALVE WALL, BODY-BONNET JOINT (COVER), STEM PACKINGSOR SEATS.
