Abstract
The utility model provides a simple and easy quick change coupler. This joint especially cooperates the connecting piece as the low temperature among the hydraulic system of aircraft in being applicable to various hydraulic pressure and pneumatic circuit. It can and then constitute a complete hydraulic system with the hydraulic component and quick the coupling together of oil pipe of dispersion. This connects differently to some extent with in the past quick -operation joint, and the out of use steel ball comes the attach fitting, is that the structure is oversimplified more. Choose the material of shape memory alloy as female connector for use. Utilizing the shape memory effect of this kind of material, changing the size of controlling the female joint internal diameter through temperature adjustment, convenient and fast's butt joint is installed and is dismantled. And at the cooperation in -process, female connector can hold the male joint tightly, and is difficult not hard up, has good leakproofness. Head in male joint and female connector cooperation position adds respectively with the afterbody has O type circle, and it has the rubber packing pad circle to fill up between the counterface, improves the sealing performance of joint more. Because shape memory alloy's pseudo - elasticity performance and damping characteristic, this joint still has good antidetonation characteristic.
Description
Technical field
This utility model belongs to a kind of joint, a kind of hydraulic quick coupler be applicable to hydraulic system.
Background technology
Hydraulic quick coupler is in mechanical industry field through commonly used a kind of joint, also known as quick connector.Hydraulic quick coupler is a kind of joint that can realize and load onto rapidly or unload, it is adaptable to need hydraulic pressure or the pneumatic circuit of frequent mounting or dismounting.Can quickly realize the quick connection between connection and the pneumatic element between conduit under fluid pressure and Hydraulic Elements.The hydraulic quick coupler currently commonly used, although effective connection can be realized, but structure is complicated, and difficulty of processing is big, and does not possess excellent sealing property.Existing snap joint is by overcoat, steel ball pressure to be fallen in the V-shaped groove of fittings body, makes two fittings bodies couple together.During dismounting, with spring, overcoat need to be pulled back, drive steel ball to be moved from V-shaped groove, and then pull-out fittings body.Component is comparatively laborious, and spring and overcoat are difficult to production and processing.
Summary of the invention
This utility model purpose be to provide a kind of simple in construction, be connected firmly, the hydraulic quick coupler of good seal performance.
For achieving the above object, the technical solution of the utility model is:
The composition component of joint includes famale connector, male contact, O, rubber gasket.No longer having overcoat, spring and steel ball on famale connector, male contact is without opening V groove.Famale connector selects shape memory alloy material, and based on its shape memory effect, its internal diameter size can change.The processing internal diameter of memory alloy material famale connector is less than the external diameter of male contact.The most expanding, make the internal diameter of the famale connector of memorial alloy be more than male contact external diameter, and then male contact is inserted location.Heat up again, due to shape memory effect, famale connector heat shrinkable, be returned to original size.Because original size is less than male joint, so and produce the big magnitude of interference between male contact, be tightly coupled together.
Further, at male contact and the head of famale connector cooperation position and afterbody respectively added with O, it is lined with rubber gasket between counterface, more improves the sealing property of joint.
The utility model has the advantage of:
1, the component such as the overcoat outside this utility model reject famale connector, steel ball, spring, simple in construction, it is easy to production and processing.Male contact does not has V groove and convex ridge, adds contact area.Bonding strength is high, good seal performance.
2, due to pseudoelasticity performance and the damping characteristic of marmem, this joint also has excellent shock-resistance features.
3, this utility model is adapted to the connection of pipelines, Hydraulic Elements.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is fundamental diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
As it is shown in figure 1, male contact 1 is stainless steel tube, plating zinc on surface, right-hand member can be threadeded with pipeline or Hydraulic Elements.Famale connector 5 is pipe joint of memory alloy, is made up of NiTiFe.Connectivity port is sealed by O 3,4 and rubber gasket 2, stops fluid leakage.
As in figure 2 it is shown, during assembling, squeezed in famale connector 5 by conical plug cylinder at low temperatures, make internal diameter expansion 7% ~ 8%.Then male contact 1 is inserted expanding after famale connector in.Along with the rising of temperature, famale connector is due to shape memory effect, and its internal diameter can be retracted to expanding front size.Thus produce the big magnitude of interference with male contact, male contact is held tightly, it is achieved connect.During dismounting, butt joint carries out cooling process, and martensitic phase transformation can occur inside famale connector, and caliber becomes big, makes connection relax, and then is separated by male contact.
Claims (2)
1. an easy hydraulic quick coupler, is made up of famale connector, male contact, O and rubber gasket, it is characterized in that: famale connector material selection marmem, and its internal diameter size can change.
Easy hydraulic quick coupler the most according to claim 1, is characterized in that at the head of male contact and famale connector cooperation position and afterbody respectively added with O.
