Abstract
The invention relates to a compound type sealed cutting ferrule of stainless steel special rubber, comprising a joint, a hard tube which is matched and connected with the joint and a nut used for closely connecting the joint and the hard pipe, wherein the wide mouth end of the nut is spirally connected with the joint, and the narrow mouth end of the nut fits the diameter of the hard pipe; a front cutting ferrule is arranged to closely cooperate with a rear cutting ferrule; the outer ring surface of a hollow annular boss of the front cutting ferrule closely cooperates with a joint chute in the joint; the inner ring surface of the hollow annular boss cuts into the body surface of the hard tube and clamps the hard pipe; the horizontal plane of the outer ring of the front cutting ferrule seals the gap between the front edge of the joint chute and a nut platform; and the beveling surface of the rear cutting ferrule and a nut chute at the narrow mouth side of the nut closely cooperate. The invention enhances the pulling-out force in hard pipe connection so that the anti-loosening and anti-vibration effects are good, and has the characteristics of high pressure resistance, high and low temperature resistance and anti-detonation property, thereby being widely applied to connecting various high pressure pipelines.
Description
Technical field
The present invention relates to the industrial fastener field, relate in particular to a kind of hermetic collar.
Background technique
In the commercial production, a large amount of various pipelines that are provided with, the traditional thread connecting mode of the many employings in its interface position; For reaching sealing effect, often need to select the annex collocation to seal common method like the employing packing ring; In this method practical application; Easyly leak, exist that safety reliability is poor, defectives such as operation inconvenience etc., especially when applications such as high pressure resistant, high-low temperature resistant, anti-explosion, can not satisfy relevant technical requirements, thereby carry out innovative design on this basis in necessity.
The invention scheme
The purpose of this invention is to provide a kind of compound type sealed cutting ferrule of stainless steel special rubber.
Technological scheme of the present invention is achieved in that
A kind of compound type sealed cutting ferrule of stainless steel special rubber is provided; The hard tube that comprises joint, is connected with joint; Be used for the closely knit nut that is connected of joint and hard tube is constituted, wide mouthful of end of nut is connected with the joint spiral, and nut slot one end and hard tube caliber are suitable; It is characterized in that: cutting ferrule and the closely knit cooperation of a back cutting ferrule before being provided with one; Interior closely knit cooperation of joint skewed slot of the outer ring surface of the hollow ring boss of cutting ferrule and joint before said, the inner ring surface of hollow ring boss is cut in the hard tube body surface, and hard tube is tightened; Before the outer shroud horizontal plane of cutting ferrule the leading edge of joint skewed slot and the gap between the nut platform are sealed closely knit cooperation of nut skewed slot of the chamfer surface of back cutting ferrule and nut slot one side.
Aforesaid compound type sealed cutting ferrule of stainless steel special rubber; It is characterized in that: said one preceding cutting ferrule and the closely knit cooperation of a back cutting ferrule are first platform of cutting ferrule before the lug ring of back cutting ferrule gets in regular turn, and compressive deformation extends to preceding cutting ferrule skewed slot and forms the closely knit press fit that receives again.
Aforesaid compound type sealed cutting ferrule of stainless steel special rubber is characterized in that: said lug ring inboard is provided with an inner groovy.
Aforesaid compound type sealed cutting ferrule of stainless steel special rubber is characterized in that: cutting ferrule is made up of preceding cutting ferrule ring and the closely knit cooperation of preceding cutting ferrule casket before said.
Aforesaid compound type sealed cutting ferrule of stainless steel special rubber is characterized in that: in second platform of cutting ferrule, the back bevel of preceding cutting ferrule ring cooperated with the chamfer surface of preceding cutting ferrule casket is closely knit before the bulge loop of cutting ferrule ring stretched into before said.
When the present invention uses; Nut, back cutting ferrule, preceding cutting ferrule are inserted on the hard tube in regular turn, the hard tube top are inserted in the port of joint last jack panel; Preceding cutting ferrule holds out against with back cutting ferrule pressurized successively; The outer ring surface of the hollow ring boss of preceding cutting ferrule and closely knit cooperation of joint skewed slot in the joint, the inner ring surface of hollow ring boss is cut in the hard tube body surface, and hard tube is tightened; The outer shroud horizontal plane of preceding cutting ferrule is with the leading edge and the sealing of the gap between the nut platform of skewed slot, and the lug ring of back cutting ferrule gets into first platform of preceding cutting ferrule in regular turn, and the skewed slot of cutting ferrule formed the closely knit press fit that receives before compressive deformation extended to again; The closely knit cooperation of nut skewed slot of the chamfer surface of back cutting ferrule and nut slot one side; Formation one need not the structure of the interlocking fastener assembly of annex setting; Hollow ring boss and preceding cutting ferrule outer shroud horizontal plane adopt the lamination layer structure of the special rubber of stainless steel when using, to strengthen the intensity and the toughness at interface position.
Pulling-out force when the present invention has strengthened hard tube and connects, locking, against shock is effective; Characteristics with high pressure resistant, high-low temperature resistant, anti-explosion; Can be widely used in the connection of various pressure ducts; Like hydraulic system, air-channel system, oil-way system, particularly extensive use on bullet train, boats and ships, aircraft.
Production technology of the present invention and technical parameter:
1, adopts the austenite stainless steel heat treatment process, increase the intensity and the cohesion of cutting ferrule self.
What 2, employing Austenitic Stainless Steel and specific rubber combined is composite structured, strengthens the soundness and the sealing that connect.
3, explosion destruction test: pressure reaches 2800 kilograms.
4, high pressure resistant: hydraulic pressure can reach more than 100 MPas.
5, pulse vibratory test: can reach 1,000 ten thousand circulations.
6, reveal test: air pressure is not less than 6.3Mpa.
7, vibration test: test time was 1,000 ten thousand times when vibration frequency was 10Hz-50Hz.
