The prepackage that complete cost function nut is installed；In the insertion nut body 1 of steel pipe 3, continuation carries out tightening action, ring-type to function nut
During the cutting edge end 111 of cutting ferrule 11 deforms upon and inserts the tube wall of steel pipe 3, when spiral shell adjacent with annular breach in ring-type cutting ferrule 11
When the outer surface of the abutting end of maternal body 1 contacts with the outer surface of locating ring 12, stop to nut screwing clamping, now, elastic seal ring
13 inner surface is in close contact with the outer surface of steel pipe 3, reaches sealing effectiveness, completes the assembling of steel pipe 3.
The function nut that the present invention is provided, elastic seal ring 13 is arranged in nut body 1 with locating ring 12, it is to avoid
The phenomenon that part is scattered during assembling, improves efficiency of assembling；When this function nut is used, ring-type cutting ferrule 11, the and of locating ring 12
Elastic seal ring 13 is used cooperatively, and is effectively prevented from gas or fluid leakage in equipment, it is also possible to prevent in device interior
Under under-voltage condition, in air access arrangement；Elastic seal ring 13 can enter row buffering to the pressure of device interior simultaneously, improve and set
Standby security；The use of locating ring 12 effectively prevent this function nut to be occurred tightening phenomenon when mounted, and was improved
The efficiency and reliability of assembling.
Further, as it is a kind of specifically can embodiment, nut body 1 formed near one end of ring-type cutting ferrule 11
There is annular projection 14, annular projection 14 is connected with the outer surface of the abutting end of nut body 1 of ring-type cutting ferrule 11.Annular projection 14 exists
Auxiliary is played a part of in use when nut is tightened to elastic seal ring 13 and locating ring 12, when nut is tightened
When, annular projection 14 acts on ring-type cutting ferrule 11, ring-type cutting ferrule 11 is moved to same direction with nut.
Further, as it is a kind of specifically can embodiment, the vulcanizing treatment of elastic seal ring 13 is connected to locating ring
On 12.
Further, as it is a kind of specifically can embodiment, be provided with rubber ring on the outer surface of locating ring 12.It is fixed
The sealing property that rubber ring further increases this function nut is provided with the outer surface of position ring 12.
Further, as it is a kind of specifically can embodiment, ring-type cutting ferrule 11 is using at non-hexavalent chromium galvanizing surface
Reason mode.Zinc coat is the most cheap protective layer of steel substrate, zinc-plated effectively to prevent this function nut from producing corrosion, is prolonged
The service life of this function nut long, the reliability for improving the practicality of this function nut and using.
In addition, Cr VI is the property swallowed poisonous substance/extremely toxic thing of imbedibility, skin contact may cause sensitivity；More likely cause
Inherited genetic defects, suction is potentially carcinogenic, and has lasting danger to environment.Cr VI is easy to be absorbed by the body, it
Human body can be invaded by digestion, respiratory tract, skin and mucous membrane：Different degrees of sand can be caused by the Cr VI breathed in air
Mute, Atrophic nasal mucosas, can also make perforation of nasal septum and bronchiectasis etc. when serious；Can be caused vomiting when being invaded through alimentary canal,
Abdomen aches；Dermatitis and eczema can be produced when being invaded through skin；Harm maximum is contact in long or short term or suction, there is carcinogenic danger
Danger.User is not injured using non-hexavalent chromium galvanizing surface processing mode, while not had a negative impact to environment, is met
Environmental requirement.
Further, as it is a kind of specifically can embodiment, elastic seal ring 13 uses quality of rubber materials.Elastic packing
Circle 13 has blocked gas or the unique leakage path of liquid in equipment, pressure fluid that not only can be in sealed tube, at the same can in case
Only pipe in it is under-voltage in the case of air enter system.The elastic seal ring 13 of this function nut has due to using quality of rubber materials
There is good pressure buffer performance, therefore, even if similarly having highly desirable sealing effectiveness under high pressure operating mode, while by
It is operated in static pressure area in elastic seal ring 13, service life is more long, improves the practicality of equipment.
Further, specifically can embodiment, rubber of the selection with oil resistant characteristic of elastic seal ring 13 as one kind
Glue, thus the material of elastic seal ring 13 can from nitrile rubber, neoprene, hydrogenated nitrile-butadiene rubber, ACM or
Fluorubber, in being originally example, preferably fluorubber as elastic seal ring 13 raw material.
Further, as it is a kind of specifically can embodiment, this function nut is the mark made according to Standard
Quasi- part, production cost is relatively low in process of production, and production efficiency is higher, while can be replaced with traditional nut, drops
The maintenance of low equipment and maintenance cost, improve the practicality of this function nut.
Further, as it is a kind of specifically can embodiment, the inner surface of this function nut scribbles lubricant.This work(
The inner surface of energy nut scribbles lubricant can effectively prevent that stuck phenomenon occurs when using this function nut, while
Elastic seal ring 13 and the inner surface and locating ring 12 of nut body 1 and the friction of the inner surface of nut body 1 are reduced, it is convenient
The installation of this function nut and use.
In addition, present invention also offers a kind of ferrule-type compression joint, including above-mentioned functions nut, also including with locating ring 12
First end face contact joint 2, one end of joint 2 is provided with the external screw thread matched with the internal thread of nut body 1.
The ferrule-type compression joint that the present invention is provided, when in use, above-mentioned function nut and joint 2 is connected by screw thread
Connect, steel pipe 3 is inserted in the inner chamber of this function nut, by function nut screwing clamping, complete the assembling of steel pipe 3；By using this card
, can be attached for many steel pipes 3 by sleeve type pipe joint.
