Abstract
A self-sealing quick change connector comprises a left connector assembly, a right connector assembly, and an outer connecting sleeve, wherein the left connector assembly comprises a left choke, a left sealing gasket, a left connector, a left valve needle in the inner chamber of the left connector, a left spring, an O-shaped sealing ring in the left connector port, and a baffle ring, wherein the left choke presses the left sealing gasket through screws to connect with the left connector, and the right connector assembly comprises a right connector, a right spring, a right valve needle, a right sealing gasket, and a right choke, wherein the outer connecting sleeve is sheathed on the right connector, and is only capable of moving between the shoulder of the right connector and the shoulder of the right choke, furthermore, the connector is capable of reliably sealing under low pressure and high pressure, having great sealing stability, and the sealing O-shaped ring is uneasy to damage.
Description
The utility model relates to a kind of oil connection, particularly a kind of self sealing oil pipe quick release coupling.
Existing self sealing oil pipe quick release coupling as shown in Figure 2, it by oil nozzle 14, pad 15, left joint 16, seal spring 17, seal steel ball 18, O-ring seals 19, sliding sleeve spring 20, sliding sleeve 21, positioning ball 22, right connector 23 constitute; When left and right splice failure, it seals steel ball 18 and seals the joint hydraulic fluid port and realize self-styled by sealing spring 17 roof pressures; When left and right joint connected, right connector 23 was stuck in the left joint 16 by positioning ball 22, left and rightly seals the mutual roof pressure of steel ball and oil circuit is connected, and the seal with O ring of radial arrangement is lived hydraulic fluid port on the left joint 16.This quick release coupling damages (especially when high pressure) owing to O shape circle is easy makes sealing unreliable; Because the opening amount at its valve port place is very little, throttling serious, the oil temperature raises easily; Because the positioning groove on the right connector weares and teares easily, make the steel ball location inaccurate again, cause the logical oil at valve port place unreliable.
The purpose of this utility model be to provide a kind of can both reliable sealing under low pressure and high-pressure situations, and the self-sealing quick-changing joint of sealing good stability.
For reaching above-mentioned purpose, the technological scheme of the self-sealing quick-changing joint of the utility model is: self-sealing quick-changing joint comprises left splice combinations, right connector combination, outer connecting sleeve, it is characterized in that: described left splice combinations is made of left oil nozzle, left sealing gasket, left joint and the O-ring seals and the back-up ring that are positioned at left needle, left spring and left splice port in the left joint inner chamber, left side oil nozzle compresses left sealing gasket by screw thread and is connected with left joint, and right connector constitutes the right connector combination with the right spring of placing successively, right needle, right sealing gasket, right oil nozzle; Outer connecting sleeve is enclosed within on the right connector, can only move between the shoulder of the shoulder of right connector and right oil nozzle; Outer connecting sleeve be enclosed within on the outside thread of left joint and screw, right connector is adjacent to back-up ring, left and right splice combinations fuses.
Because adopt said structure, the self-sealing quick-changing joint of the utility model has the following advantages:
1, the sealing of the radially O-ring seals of left and right joint is become the end face seal of being made up of O-ring seals and Sealing shield ring, can seal the above high pressure of 80MPa reliably, and O shape circle is not fragile;
2, the needle of band awl mouth backs down backward mutually and opens self-styled valve port, can obtain bigger unlatching distance, makes oil circuit more smooth and easy, and throttling is littler, the reliability that the raising system uses;
3, hand is screwed to connect cover, with the left and right sides oil circuit that is threaded, makes the end face of left and right joint can be adjacent to Sealing shield ring reliably, seals more reliable.
Below, in conjunction with the accompanying drawings and embodiments, the structure characteristic of the self-sealing quick-changing joint of the utility model is further described.
Fig. 1: the utility model self-sealing quick-changing joint structural representation;
Fig. 2: existing self-sealing quick-changing joint structural representation.
Embodiment
A kind of self-sealing quick-changing joint.Comprise left splice combinations, right connector combination, outer connecting sleeve 8, it is characterized in that: described left splice combinations is made of left oil nozzle 1, left sealing gasket 2, left joint 3 and the O-ring seals 6 and the back-up ring 7 that are positioned at left needle 4, left spring 5 and left splice port in the left joint inner chamber, left side oil nozzle 1, compress left sealing gasket 2 by screw thread and is connected with left joint 3, right connector 9 makes up with right spring 10, right needle 11, right sealing gasket 12, right oil nozzle 13 formation right connectors; Outer connecting sleeve 8 is enclosed within on the right connector 9, can only move between the shoulder of the shoulder of right connector 9 and right oil nozzle 13; Outer connecting sleeve 8 be enclosed within on the outside thread of left joint 3 and screw, right connector 9 is adjacent to back-up ring 7, left and right splice combinations fuses.
During work, the outer connecting sleeve 8 of turn, O-ring seals 6 suitable compressive strains, simultaneously, left needle 4 and right needle 11 back down mutually backward, make oil circuit unimpeded; Connecting sleeve 8 outside screwing off, and when left and right splice combinations was thrown off, the needle 4,11 of band awl mouth was sealed hydraulic fluid port and realized self-styled under the roof pressure of left spring 5, right spring 10.
