Description
Technical field
The utility model relates to field of fluid, particularly a kind of fluid coupling.
Background technique
Usually adopt the Hard link of thread forms between fluid line and joint unit, this hard connecting mode is simple and reliable.And at some and fluid line be relative rotation status parts on, this hard connecting mode also cannot be suitable for, and therefore people have done many improvement for the linkage structure between these operating mode convection cell pipeline and joint units.
Shown in Fig. 1 be at present can realize the fluid coupling schematic diagram of mutual spinfunction between a kind of fluid line of commonly using and joint unit, in figure, tool joint pin 4 is provided with a circular groove 41, female joint 3 is processed with the tapped hole 31 corresponding with described circular groove 41, tapped hole 31 is provided with stop screw 32, stop screw 32 is stuck in circular groove 41, makes mutually rotate along axis and not come off between female joint 3 and tool joint pin 4.But in rotary course, the groove side of the outer peripheral surface meeting scraping circular groove 41 of stop screw 32, thus produce larger heat and damage the groove side of circular groove 41, a large amount of Integrated Chip can be there is in long-time use circular groove 41, groove width also therefore broadens and is out of shape and the axial float between pin and box sub is aggravated, when the two may wear to the danger of to a certain degree happen occasionally fluid leakage or Joint's falling off, on stop screw 32, the built-up edge of attachment also makes stop screw 32 be difficult to take out usually, impact dismounting.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of fluid coupling that can improve scraping phenomenon between fluid coupling in rotary course.
For achieving the above object, the utility model is by the following technical solutions:
The rotatable fluid coupling of a kind of high reliability, it comprises female joint and tool joint pin: the tip side of described female joint is provided with a circle jump-ring slot along excircle, direction along described jump-ring slot is provided with some through holes, all steel ball is installed in described through hole, described jump-ring slot is equipped with the axle jump ring of fixing described steel ball; Described tool joint pin tip side outer circumferential face is provided with the circular groove corresponding with through hole in shown female joint, and the steel ball in female joint can drop in this circular groove, and the outer peripheral surface between circular groove and splice port is provided with seal construction.
Preferably, described number of openings is three, the circumferencial direction along described jump-ring slot be separated by 120 degree uniform.
Preferably, described seal construction is made up of O type circle groove and O RunddichtringO, and O RunddichtringO ring set is on O type circle groove.
Preferably, described public access head end is multidiameter shaft, and O shape groove place end diameter is less than blind hole place end diameter, and female joint and tool joint pin fitting surface correspond to shoulder hole.
Preferably, the other end of described tool joint pin and female joint is equipped with for refuting the pagoda head connecing fluid line.
After adopting technique scheme, the utility model is compared with background technique, and tool has the following advantages:
When male and female joint rotates mutually, being arranged on steel ball in female joint through hole can Free-rolling in the circular groove in tool joint pin under the restriction of female joint through hole and axle jump ring, thus high degree reduces the grinding phenomenon produced when male and female joint rotates mutually, this fluid coupling is rotated flexibly, has possessed better durability and reliability
Accompanying drawing explanation
Fig. 1 is existing rotatable fluid coupling schematic diagram
Fig. 2 is high reliability rotatable fluid coupling female joint schematic diagram
Fig. 3 is high reliability rotatable fluid coupling tool joint pin schematic diagram
Fig. 4 is the rotatable fluid coupling schematic diagram of high reliability
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, Figure 3 and Figure 4, the rotatable fluid coupling of high reliability comprises female joint 1 and tool joint pin 2.
The tip side of female joint 1 is provided with a circle jump-ring slot 13 along excircle, and the direction along described jump-ring slot 13 is provided with some through holes 11, is all provided with steel ball 12 in described through hole 11, described jump-ring slot 13 is equipped with the axle jump ring 14 of fixing described steel ball 12
Tool joint pin 2 tip side outer circumferential face is provided with the circular groove 21 corresponding with through hole 11 in shown female joint 1, and the steel ball 12 in female joint 1 drops in this circular groove 21, and the outer peripheral surface between circular groove 21 and splice port is provided with seal construction.Sealing structure is made up of O type circle groove 22 and O RunddichtringO 23, and O RunddichtringO 23 ring set on O type circle groove 22, thus plays seal action to the fitting surface of pin and box sub, and the flowing medium such as gas or liquid can not leak when joint inner flow passage flows.
Tool joint pin 2 termination head end is multidiameter shaft, and O shape groove 22 place end diameter is less than circular groove 21 place end diameter, and the tip side that female joint 1 coordinates with tool joint pin 2 corresponds to shoulder hole.Female joint 1 and tool joint pin 2 and the other end be respectively equipped with for refuting the pagoda head 15 and 24 connecing fluid line.
O RunddichtringO 23 described in the present embodiment and axle jump ring 14 are standard piece, and described O type circle groove 22 and jump-ring slot 13 are by corresponding standard design.
So, to the tip side of the tool joint pin 2 of O-ring seals 23 ring set on O shape groove 22 be inserted in the tip side of female joint 1, steel ball 12 is put in the through hole 11 in female joint 1, steel ball 12 drops in the annular groove 21 of tool joint pin 2 correspondence, uses Circlip tongs to be fixed on by axle jump ring 14 on jump-ring slot 13 and just completes the fixing of steel ball 12.Steel ball 12 serves connection pin and box sub at this and does not throw off and the effect that can mutually rotate, steel ball 12 is ganoid rolling element, friction factor is little, not fragile annular groove 21, thus complete docking of female joint 1 and tool joint pin 2, male and female joint can be rotated freely along tip side axis, possessed good endurance quality and high reliability.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
