Description

Technical Field

[0001] This utility model belongs to the field of oil circuit self-sealing technology, specifically relating to a self-sealing connector that realizes the function of connecting and disconnecting oil circuits, and can seal the oil after disconnecting the oil circuit to prevent oil leakage. Background Technology

[0002] Currently, conventional self-sealing valves have a simple structure, but oil leakage often occurs during disconnection and connection. Furthermore, there are no anti-loosening measures, which can easily cause the joint to separate during the flow process. Utility Model Content

[0003] The purpose of this invention is to provide a self-sealing connector that enables the connection and disconnection of an oil circuit. When not connected, the sealing ring on the valve forms a sealing pair with the housing through the spring force, preventing oil leakage and achieving a self-sealing function. When connected, the valve core at the other end of the connector presses against the valve's compression spring, causing the valve to open and creating a passage, thus enabling the oil circuit to be connected.

[0004] This utility model provides a self-sealing connector for connecting and disconnecting oil circuits, comprising a nozzle, flange, retaining ring, elastic pressure ring, connecting toothed ring, housing, valve, sealing ring I, sealing ring III, sealing ring II, protective ring, and spring. One end of the nozzle has an external thread that is threadedly connected to the internal thread of one end of the housing for sealing. The other end of the nozzle has an inlet, and the other end of the housing has an interface. The valve is located inside the housing, with one end face sealingly connected to the conical surface of the inner end face of the housing. The other end of the valve has an axial groove. One end of the spring abuts against the bottom end face of the groove, and the other end abuts against the inner end face of the nozzle near the inlet. The valve sidewall has a through hole. The outer side of the housing near the nozzle end has a flange, retaining ring, elastic pressure ring, and connecting toothed ring arranged sequentially. The retaining ring, elastic pressure ring, and connecting toothed ring are placed in an annular groove on the outer side of the housing. The inner side of the housing near the interface end has an annular groove for placing sealing ring I.

[0005] Furthermore, a groove is provided at the connection between the valve end face and the inner end face of the housing for sealing ring III. The end face sealing method can prevent oil leakage when the oil circuit is disconnected.

[0006] Furthermore, the housing has a groove at the contact point with the nozzle for placing the sealing ring II and the protective ring to prevent oil leakage.

[0007] When an oil circuit connection is required, the self-sealing connector mates with the other end connector. The valve core of the other end connector presses against the valve spring of the self-sealing connector to open the valve, forming a passage and realizing the function of connecting the oil circuit. When the oil circuit needs to be disconnected, the other end connector separates from the self-sealing connector. The valve in the self-sealing connector returns to its original position by the spring force and forms a sealing pair with the housing through a sealing ring to prevent oil from flowing out and realize the function of self-sealing.

[0008] The beneficial effects of this utility model are:

[0009] (1) The product has the function of quickly connecting the oil supply line connector;

[0010] (2) The product has an automatic sealing function to prevent oil from flowing out of the pipeline;

[0011] (3) The product has an automatic anti-loosening function. The product is designed with a ratchet pawl in the ratchet mechanism. When it is engaged with the ratchet of another connector, it can achieve anti-loosening.

[0012] (4) The product seal adopts conical surface seal and shaft hole seal; it can achieve sealing during docking and disconnection processes;

[0013] (5) Operators can connect and disconnect the self-sealing connector to another connector by hand. Attached Figure Description
