多年以后,我还是没有想明白。那颗没有伤到工藤的子弹,为何会让他将自己忘得那么彻底,像从未存在过般的干净、决绝。是因为我本就是你无关紧要的人,还是说,我给你的那五个字过于沉重。只有丢掉它,你才会无所顾虑?工藤,我爱你。、十年前,那个射向工藤的子弹被我挡了下来,而一觉醒来的我,什么都忘了。唯一记得的是他,工藤新一。于是我发...

If the installation of the apparatus requires the application of compression fittings in the field, these must be installed following the instructions of the manufacturer of the fittings themselves. The choice of the fitting must be compatible with the use specified for the apparatus and with the specifications of the system when envisaged.COMMISSIONINGCommissioning must be carried out by adequately trained personnel. During the commissioning activities, the personnel not strictly necessary must be ordered away and the no-go area must be properly signalled (signs, barriers, etc.). Check that the settings of the apparatus if necessary, reset them to the required values in accordance with the procedures indicated in the manual. When commissioning, the risks associated with any discharges into the atmosphere of flammable or noxious gases must be assessed. In installations in natural gas distribution networks, the risk of the formation of explosive mixtures (gas/air) inside the piping must be considered.PRECAUTION FOR THE OPERATORSBefore proceeding with installation, commissioning or maintenance, operators must: Examine the safety provisions applicable to the installation in
Obtain the authorisations necessary for w Use the necessary means of individual protection (helmet, goggles, etc.); Ensure that the area in which they operate is fitted with the means of collective protection envisaged and with the necessary safety indications.CONFORMITY TO DIRECTIVE 97/23/EC (PED)Pressure regulator Dival 600 is classified as pressure accessory according to directive 97/23/EC (PED). The pressure regulator Dival 600 with embedded block device, with pressure switch for tripping in case of maximum pressure, is defined as a safety accessory according to PED Directive and, therefore, it can be used both as a pressure accessory and a safety accessory, always according to the PED Directive. The configuration of the regulating pressure regulator plus in line monitor regulator is defined as safety accessory according to the PED Directive. In this case the user shall verify that the maximum allowable pressure (PS) of pressure equipment to be protected is consistent with setting and closing class (SG)
the pressure inside pressure equipment shall be lower than 110% of PS. Conformity with Directive 97/23/EC and CE marking of pressure regulator and relevant accessory require installation in the system with minimum requirements according to EN 12186).HANDLINGThe handling of the apparatus and of its components must only be carried out after ensuring that the lifting gear is adequate for the loads to lift (lifting capacity and functionality). The apparatus must be handled using the lifting points provided on the apparatus itself. Motorised means must only be used by the persons in charge of them.PACKINGThe packing for transportation of equipment and of relevant spare parts are designed and shaped to avoid damage to any part during transportation, warehousing and handling activities. Therefore the equipment and spare parts shall be kept into their packing until their installation in the final site. After packing is open, check that no damage occurred to any goods. If damage occurred inform the supplier and keep packing for any verification.INSTALLATIONThe installation of the pressure regulator has to occur in compliance with the provisions (laws or standards) in force in the place of installation. In detail, natural gas plants have to show features in compliance with the law provisions and standard requirements in force in the place of installation or at lease in compliance with standards EN 12186 or EN 12279; in detail, it is necessary to meet the provisions of paragraphs 6.2, 7.5.2, 7.7, 9.3 of the standard EN 12186 and 6.2, 7.4, 7.6, 9.3 of the EN 12279 standard. The installation in compliance with such standards minimizes the risk of fire hazard and the formation of potentially explosive atmospheres. The valve is not equipped with external pressur therefore, it has to be installed making sure that the operating pressure of the assembly on which it is installed does not exceed the maximum allowable pressure (PS). Therefore, the user, as deemed necessary by the same, shall install on the assembly suitable pressure limitation systems, as well as provide the plant with suitable relief or drain systems in order to discharge theTecnical Manual MT 185-E3- INDEX -.1.01.1 1.2 1.3INTRODUCTION45.05.1 5.2 5.3 5.4 5.5START UPGENERAL GAS INPUT, CONTROL OF EXTERNAL TIGHTNESS AND SETTING COMMISSIONING THE REGULATOR COMMISSIONING THE REGULATOR WITH INCORPORATED LA/..SLAM-SHUT COMMISSIONING THE REGULATOR PLUS DIVAL 600 IN LINE MONITOR WITH INCORPORATED LA/..

It is also appropriate to provide a brief illustration of the main features of the regulator and of its accessories.The pressure regulator is equipped with two anti-pumping devices 33 and 34 (fig. 1), which are in charge of slowing down the inflow/outflow of the gas/air in the head only during the transitory phases, in order to avoid possible oscillation phenomena of the regulated pressure. There are also two stops V1 and V2 for the purpose of eliminating damaging effects which could derive from accidental over-pressures below the diaphragm 19 or from overloading of the spring 43. Usually, a solution of the type shown in fig. 2a is adopted in order to protect the obturator against damages resulting from sudden increases of the regulated pressure.1.1MAIN FEATURESThe DIVAL 600 pressure regulator is a pressure regulator for previously cleaned gaseous fluids and is suitable for medium and low pressures. The DIVAL 600 is a normally open regulator and consequently opens in the event of: - Breakage o - No regulated pressure signal. The main specifications of this regulator are: - Design pressure PS: up to 20 - Operating Temperature range: -20 °C to + 60 °C; - Ambient Temperature range: -20 °C to + 60 °C; - Inlet pressure range bpu: 0,2 to 20 - Possible regulation range Wd: 10 to 350 mbar for head ? 280; 280 ÷ 4400 mbar for head ? 280/TR; - Minimum differential pressure: 0.1 - Accuracy class AC: up to 5 (according to the output pressure field); - Lockup pressure class SG: up to 10 (according to the output pressure field)1.2OPERATION OF THE PRESSURE REGULATOR DIVAL 600 (fig. 1)In absence of pressure the obturator 3 is kept in open position from the hook of shaft 9 on the side of the levers 13 (fig. 1). The outlet pressure Pd is checked through the comparison between the load of the spring 43 and the impulse of the outlet pressure on the membrane 19. In this comparison are involved also the weight of the mobile equipment and the dynamic thrusts on the obturator. The upstream pressure, although it is variable, has not any influence on the balance of the obturator 3, since this latter, due to the presence of the hole A, is positioned between two equal pressures acting on equal surfaces. The movement of the diaphragm 9 is transmitted by the lever system 13 to the stem 9 and hence to the obturator 3. The obturator 3 is fitted with a vulcanized rubber gasket to ensure perfect tightness with zero flow rate demand. If, during operation, the downstream pressure drops, the force it exerts on the diaphragm 19 becomes lower than the load of the spring 43. The diaphragm therefore drops and, by means of the lever system 13, pulls the obturator 3 away from the valve seat 2. The gas flow, therefore, increases until the initial pressure set-point is restored. If, on the other hand, the downstream pressure begins to increase, the force exerted on the diaphragm 19 exceeds the load the spring 43. The obturator is therefore displaced towards the closed position, returning the downstream pressure the set-point. In normal working conditions, the obturator 3 is positioned in such a way as to maintain the pressure Pd around the selected set-point. To adjust the pressure set-point you con turn the internal adjustment ring 28 appropriately, clockwise to increase and anticlockwise to reduce it. Normally the plug is only used the cover the lower band of the va the adjusting screw is used for the higher values.fig. 1In fact, this solution allows the diaphragm protection disc 20 to rest on the upper stroke end V1 exceeding the load of the spring 42 and thus releasing the obturator from the load resulting from the sudden pressure increase. In order to prevent small leaks at null required flow rate or that sudden and temporary overpressures, resulting for example from fast manoeuvres or gas overheating, may let the slam-shut valve trip, the solution shown by fig. 2a can be transformed, upon request, into an embedded relief valve, eliminating the O-ring 73 and adding the ring 70 (fig. 2b). Its operation is described as follows: with closed regulator, any overpressures lift the diaphragm protection disc 20 exceeding the load of the springs 42 and 43. In this way, a given quantity of gas is discharged through the seat Z of the relief valve.包含各类专业文献、中学教育、专业论文、高等教育、外语学习资料、幼儿教育、小学教育、行业资料、各类资格考试、15Dival600使用说明书等内容。
