Abstract
The utility model provides an improved hydraulic rapid joint belonging to components on hydraulic equipment. A partition plate is installed at the inner side of a connector, one end of a self-locking push rod is inserted to the partition plate, and the other end is installed in a male connector; and both sides of a female connector are respectively provided with the male connector and the other male connector, the other male connector is installed together with the female connector through threads, the male connector is inserted together with the other male connector, the outer insertion surface of the male connector is a conical surface, the inner insertion surface of the other male connector is the other conical surface corresponding to the conical surface, and a sealing ring is installed between the two conical surfaces. In the rapid joint, since the rubber sealing ring forms primary sealing, and the conical surfaces on the two male connectors form secondary sealing, after the secondary sealing surface is abraded or scratched, the female connector can be tightly screwed with the other male connector so that the rapid joint achieves the effect of secondary sealing, which fully ensures the sealing reliability and prolongs the service life.
Description
Technical field
The utility model provides the parts on a kind of hydraulic equipment, especially a kind of hydraulic joint.
Background technique
Hydraulic quick coupling as connected element, is a kind of easily damaged parts in hydraulic equipments such as the operation tractor hoist of petroleum production industry, pumping unit washing machine.Aspect the reliability and Economy of hydraulic equipment use, it often becomes restricted parts, has influence on the overall performance of equipment.The structure of present hydraulic quick coupling is, it has connecting head, the connecting head installed inside has dividing plate, one end of self-locking push rod is inserted in the dividing plate, the other end is installed in and connects in the male, connection female both sides are separately installed with the connection male and are connected male with another, to be connected male plug-in with another to connect male, one end of another self-locking push rod is inserted in another connection male, the other end is inserted in another dividing plate, another dividing plate is installed in the inboard of another connecting head, and the outside of the reeve dividing plate end of two self-locking push rods is respectively installed with Returnning spring.The shortcoming of this hydraulic quick coupling is fragile, causes connecting losing efficacy, and is difficult for repairing, and causes waste.By investigation statistics, find because seal failure accounts for about 98% of rapid pipe joint failure cause to existing hydraulic quick coupling failure cause.The main cause that rubber seal lost efficacy is that rubber seal damage and the actual working pressure that wearing and tearing cause is higher than the working pressure that rubber ring can bear.And because the sealing surface on the existing hydraulic quick coupling is cylindraceous facing directly, sealing surface in a single day wear and tear or have harder impurity to scratch after will form leakage, and can not repair and utilize once more.Rubber seal also is arranged on this and faces directly.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of improved hydraulic quick coupling is provided, and to prolong its working life, improves the reliability of its use.
The utility model is to realize like this, a kind of improved hydraulic quick coupling, it has connecting head, the connecting head installed inside has dividing plate, one end of self-locking push rod injects in the dividing plate, the other end is installed in and connects in the male, connection female both sides are separately installed with the connection male and are connected male with another, another connect male by screw thread be connected female and be installed together, to be connected male plug-in with another to connect male, the outer plug surface that connects male is a conical surface, and another interior plug surface that connects male is and corresponding another conical surface of this conical surface, between two conical surfaces seal ring is installed, one end of another self-locking push rod is inserted in another and connects in the male, the other end injects in another dividing plate, and another dividing plate is installed in the inboard of another connecting head, and the outside of the reeve dividing plate end of two self-locking push rods is respectively installed with Returnning spring.
Adopt the hydraulic quick coupling of said structure, rubber seal figure forms once sealing, the two contact-type tapering mechanical seals that connect the conical surface on the male form secondary seal, can after secondary seal surface wear or scuffing, the connection female can be connected male with another tightens, reach the effect of sealing once more, fully ensured the reliability of sealing, prolonged working life.Connecting head, dividing plate, self-locking push rod, Returnning spring etc. can adopt the corresponding part on the existing hydraulic quick coupling, the application of can putting into production quickly.

Embodiment
The embodiment who provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.
As shown in drawings, a kind of improved hydraulic quick coupling of the utility model, it has connecting head 1, the connecting head installed inside has dividing plate 2, one end of self-locking push rod 3 injects in the dividing plate, the other end is installed in and connects in the male 4, connection female 6 both sides are separately installed with connection male 4 and are connected male 7 with another, another connect male by screw thread be connected female and be installed together, the connection male is connected male 7 with another plug-in, the outer plug surface 41 that connects male is a conical surface, and another interior plug surface 71 that connects male is and corresponding another conical surface of this conical surface, seal ring 5 is installed between two conical surfaces, one end of another self-locking push rod 8 is inserted in another and connects in the male, the other end injects in another dividing plate 9, another dividing plate is installed in the inboard of another connecting head 10, and the outside of the reeve dividing plate end of two self-locking push rods is respectively installed with Returnning spring 11.
The material of seal ring is a fluorine sulfonated polyethylene rubber.
Connecting head, dividing plate, self-locking push rod, Returnning spring etc. adopt the counterpart on the existing hydraulic quick coupling.The profile of connection female and external structure are also with existing identical.
This hydraulic quick coupling is also identical with existing hydraulic quick coupling with Placement, the catenation principle of connected piece, repeats no more.
Obviously, " another interior plug surface 71 that connects male is and corresponding another conical surface of this conical surface " is meant, the conical surface that connects the outer plug surface of male, identical with another tapering of conical surface of interior plug surface that connects male, two conical surfaces can be docking together.
The same with existing hydraulic quick coupling, Returnning spring is sleeved on the outside of the reeve dividing plate end of two self-locking push rods, and is positioned at the inner chamber of dividing plate, and an end of Returnning spring withstands on the connecting head, the other end withstands on the self-locking push rod.
On this hydraulic quick coupling, seal ring is realized once sealing, and two conical surfaces that connect on the male form secondary seal.Connect male and be connected the contact stress that the power that screws between the female changes two conical surfaces by adjusting another, the adjustable sealing performance makes secondary seal fully reliable.After the wearing and tearing of two conical surfaces, can further screw another and connect male, make contact stress increase, reach the effect of sealing once more, fully ensured the reliability of sealing.This thread connecting mode also is convenient to maintenance, the replacing of each parts.
