1、AECMA interest: Future revisions of this standard shall be coordinated with AECM C-4.AEROSPACE STANDARDMA2114 REV.AIssued 1985-02Revised 1988-02Reaffirmed 2004-07Superseding MA2114Adapter - Port Connection, Ring LockedInstallation and Removal of1. PURPOSE AND SCOPE:This SAE Aerospace Standard provid

2、es the essential minimum design, installation and removal standard for MA 2111, MA 2112, and MA 2113 adapters and is applicable when specified on engineering drawings, or in procurement documents.2. GENERAL DESIGN INFORMATION:2.1 These adapters provide a semi-permanent male fitting primarily for use

3、 in 28 000 kPa fluid systems compatible with titanium.2.2 Adapters per MA 2111, MA 2112 and MA 2113 installed per this document into bosses and ports per MA2110 shall have a stand-off per dimension “P” Fig. 1 and Table I.2.3 O-ring size per Table I and per MA 2010 must be used. The O-ring compound s

4、hall be specified by the using design activity and shall be selected based on system fluid and temperature.2.4 The lockring is driven into the mating port serrations after the adapter has been torqued. This prevents the adapter from rotating in the port during coupling nut assembly or disassembly an

5、d also eliminates the necessity of lock wiring the adapter. Only one wrench is required to install or remove the coupling nut.2.5 Adapter removal is accomplished by lifting the lockring out of the port using a removal tool per TableII.SAE Technical Standards Board Rules provide that: “This report is

14、SAE MA2114 Revision A- 4 -TABLE III4. INSTALLATION OF ADAPTER MA 2111, MA 2112 OR MA 2113 INTO BOSS PER MA2110:4.1 O-ring Installation:4.1.1 Place the O-ring tool (per Table II) over the small thread of the fitting. Submerge the adapter, bullet and O-ring in the fluid to be used in the working syste

15、m, or a lubricant compatible with the system fluid and all components. Slide the O-ring over the bullet and onto the fitting. Be sure that the O-ring is not twisted and is properly seated in the groove of the fitting. See Fig. 2.Copyright SAE International Provided by IHS under license with SAENot f

17、ant as specified in 4.1.1. Scratches, dings or rough spots are not allowed in O-ring contact area on the adapter or in the port.4.2.2 Insert the smaller thread of the adapter into boss port by hand using a clockwise rotation until the adapter is seated. To avoid possible O-ring damage, the adapter s

18、hould not be rotated in a counterclockwise direction.4.2.3 Using the applicable combination wrench and drive tool in Table II, engage the serrations of the tool with those on the external serrations of the adapter lockring per Fig. 3. Place a torque wrench of the proper size over the hex of the wren

19、ch and apply a torque equal to the minimum value specified in Table II. Note the relationship of the serrations of the lockring with respect to the prebroached serrations in the port. If they match, proceed to 4.2.4. If the serrations do not match the prebroached serrations in the port, continue to

20、slowly torque the adapter toward the maximum value allowed in Table II until the serrations of the lockring match the boss serrations. This shall normally take between 3 and 8 degrees of turning and the maximum value need not be reached if the serrations align themselves prior to that value. Do not

21、exceed maximum torque values.4.2.4 Apply enough zinc chromate primer (MIL-P-8585) with a brush or small syringe to the counterbore area of the boss and below the adapter lockring so primer will be extruded out between external serrations of the lockring and the serrations in the port when lockring i

22、s installed. Note: Using design activity may specify another primer in place of, or in addition to, zinc chromate (see 3.1.7).Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-SAE MA2114 Revision A- 6 -F

23、IGURE 3 - Torquing Adapter Assembly4.2.5 While the zinc chromate (or other primer) applied per 4.2.4 is still wet, install the lockring by rotating the threaded end of the combination wrench and drive tool clockwise onto the adapter assembly until it touches the lockring. Using an open end or socket

24、 wrench on the tool, turn the tool in a clockwise direction until it bottoms on the boss surface as shown in Fig. 4. Visually observe that the tool has bottomed. Caution: Any sudden increase in torque prior to bottoming may indicate that the lockring serrations and the port serrations are not aligne

25、d. If this occurs, remove wrench and drive tool by turning counterclockwise. Lift the lockring per 6.2. Continue to tighten fitting clockwise per 4.2.3 until serrations in boss and the external serrations on the lockring are aligned. Again attempt to install lockring. Remove excess primer on surface

26、 of boss and lockring.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-SAE MA2114 Revision A- 7 -FIGURE 4 - Lockring Installation5. PRESSURE TESTING:5.1 A pressure test of unit may be conducted at this

27、point. Place a pressure cap on the adapter. Pressurize the unit from another location on the unit to 1.5 times the operating pressure for three minutes. There shall be zero leakage. Note: The using design activity may require testing other than shown. See 3.1.8.6. REMOVAL OF ADAPTER:6.1 If an additi

28、onal sealant has been used to cover lockring, carefully remove sealant to expose lockring.6.2 Lockring Retraction:6.2.1 Select the proper size removal tool from Table II.6.2.2 Spread the puller halves apart by retracting the sleeve from the tool until the pin bottoms in the groove of the sleeve per

29、Fig. 5. Holding the puller halves apart, place tool over protruding adapter so the nylon pad rests on the top surface of the adapter. Release the puller halves and locate in the groove of the lockring. Adjustment up or down is achieved by rotating the bolt head. Slide the sleeve over the puller halv

30、es and check for proper engagement of the puller halves in the lockring groove.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-SAE MA2114 Revision A- 8 -FIGURE 5 - Lockring Retraction6.2.3 Place wrench

31、 on the bolt head of the removal tool and turn in a clockwise direction while holding the sleeve with the other hand. This action shall cause the lockring to be jacked out of the port counterbore. When the external serrations of the lockring are clear of the boss surface, the turning may be stopped.

32、 Remove the tool from the adapter by loosening the bolt and lifting the sleeve to free the puller halves.6.3 Remove Adapter from Port:6.3.1 Select the proper size combination wrench and drive tool from Table II. Engage the serrations of the wrench with those of the lockring. Using an open end or soc

33、ket wrench over wrench hex, turn in a counterclockwise direction to disengage the adapter from the boss port. Plug the port minor diameter when cleaning out the cavity to avoid contamination of the fluid system.7. REINSTALLATION OF ADAPTER:7.1 Reinstall the adapter per section 4 using a new O-ring per Table I and 2.3.PREPARED BY SAE SUBCOMMITTEE G-3B, AEROSPACE FITTINGS,OF SAE COMMITTEE G-3, AEROSPACE FITTINGS, HOSE & TUBING ASSEMBLIESCopyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-
