Firmly, it realizes that slotting straight coupling 1 is fixed in nut seat 2 fastly not falling off, and lock-bit circlip 4 is assisted to limit slotting straight coupling 1 fastly
Sliding space in nut seat 2 prevents lock-bit circlip 5 from falling off.It inserts when straight coupling 1 squeezes down and makes fastly in the above process
Dustband 13 is compressed, and after the positioning snap ring 52 of lock-bit circlip 5 blocks the cell wall of lock-bit slot 11, compressed dustband 13 is opened
Begin to spring back, drives fast slotting straight coupling 1 to reset to position as shown in Figure 1, simultaneously because lock-bit circlip 5 blocks the slot of lock-bit slot 11
Wall, so that lock-bit circlip 5, locating ring 6 and auxiliary lock-bit circlip 4 are sprung back together with fast straight coupling 1 of inserting, until such as Fig. 1
Shown position.The mutual cooperation of 63 chamfered portion of bulge loop and 23 chamfered portion of fixing groove as shown in Figure 8 as shown in Figure 5 is to fixed
Position circle 6, which resets, plays guiding role, so that 6 springback process of locating ring is stablized.Locating ring 6 reset after, auxiliary lock-bit circlip 4 with
Lock-bit circlip 5 loses expansive space, firmly locks the cell wall of lock-bit slot 11.The cooperation that nut seat 2 is finally passed through into internal and external screw thread
It is fixed on pipe joint chair 7, so far completes entire assembly.
When needing to dismantle, first checking has without pressurization in pipeline, then unscrews pipe joint chair 7 and nut seat 2, then use exclusive clamps
The chase slot 31 outside retainer plate 3 is stated in clamp residence, is firmly pulled and is unloaded the retainer plate 3 outward.Again from locating ring 6
Circlip locating slot 61 present in gap insertion disassembly hook, and from side pull out lock-bit circlip 5, relieve lock-bit circlip 5 with
The locking of 11 cell wall of lock-bit slot.Then locating ring 6 is moved down, until auxiliary lock-bit circlip 4 obtains expansive space.Again from fixed
Insertion disassembly hook in gap present in auxiliary circlip locating slot 62 on position circle 6, and auxiliary lock-bit circlip 4 is pulled out from side, then
Locating ring 6 is taken out from fast 1 head of straight coupling of inserting, slotting straight coupling 1 can be extracted out from nut seat 2 fastly at this time, finally
Other component is removed.
Need to check whether nut seat 2 and the first sealing ring 12, the second sealing ring 24, dustband 13 damage before assembling again
It is bad.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, should all be fallen into the protection scope of the utility model.
