[0028] As Figures 1-5As shown, the present embodiment proposes a one-way flow resistant high-pressure release hose, which comprises a metal woven rubber hose 4 and two hose joints 3 at both ends, wherein the outer end of one end hose joint 3 is provided with a container valve end joint 1, the outer end of the other end hose joint 3 is provided with a manifold end 5, the hose joint 3 in the container valve end joint 1 is provided with a linkage groove 6, the inner end of the linkage groove 6 is provided with a linkage ring 7, the outer end of the linkage ring 7 is provided with a one-way valve 2, the outer end of the linkage ring 7 is provided with an extrusion arc plate 9 and a linkage silica gel block 10, the outer end of the linkage silica gel block 10 is provided with a linkage block 11, the outer end of the linkage block 11 is provided with a moving threaded rod 12, the outer end of the moving threaded rod 12 is provided with a positioning threaded ring 13, the lower end of the extrusion arc plate 9 is provided with an extrusion plate 8, the outer end of the extrusion plate 8 is provided with a linkage spring 14 and a downward moving groove 15, and the outer end of the moving threaded rod 12 is provided with a positioning rubber ring 16.

[0029] The metal weaving enhances the pressure resistance of the hose, and the rubber material ensures the flexibility and corrosion resistance of the hose, so that the hose has good adaptability and durability while bearing high pressure.

[0030] The one-way valve 2 is fixedly connected with the linkage ring 7, the linkage ring 7 is movably connected with the linkage groove 6, the linkage groove 6 is embedded and installed at the inner end of the hose joint 3, and the one-way valve 2 is provided with a plurality of sealing rings between the hose joint 3.

[0031] Through the ingenious design of the one-way valve 2, it is ensured that the gas can only flow from the container to the manifold in one direction, effectively preventing the reverse flow of high-pressure gas in other containers, avoiding the imbalance of system pressure caused by reverse flow, and enhancing the operation safety.

[0032] Usually a group of steel cylinders are connected together for use through the collecting pipeline, and the one-way valve 2 can avoid the reverse flow of gas in other steel cylinders.

[0033] The precise cooperation of the linkage ring 7 and the linkage block 11, as well as the action of the extrusion arc plate 9 and the extrusion plate 8, makes the connection between the hose joint 3 and the one-way valve 2 more stable, reduces the risk of leakage during connection, and improves the connection efficiency.

[0034] By setting a plurality of sealing rings between the one-way valve 2 and the hose joint 3, and the close combination of the positioning rubber ring 16 and the sealing ring bin, the sealing performance of the hose connection part is greatly enhanced, the leakage of high-pressure gas is prevented, and the stable operation of the system is ensured.

[0035] The upper end of the linkage ring 7 is provided with a ring groove, the inner end of the ring groove is in contact with the extrusion arc plate 9 and the linkage silica gel block 10, the outer end of the linkage silica gel block 10 is fixedly connected with the linkage block 11, and the head end of the moving threaded rod 12 is movably connected with the inner end of the linkage block 11.

[0038] The outer end of the hose joint 3 is provided with a sealing ring chamber, the sealing ring chamber is penetrated by the positioning threaded ring 13, and the positioning rubber ring 16 is wrapped around the inner end of the positioning threaded ring 13.

[0039] In use, in the installation process, first, the inner end of one of the hose joints 3 is connected to each other through the linkage ring 7 and the linkage groove 6, and the linkage block 11 and the extrusion plate 8 are moved through the mobile threaded rod 12, in this process, the linkage silica gel block 10 located at the front end of the linkage block 11 and the extrusion arc-shaped plate 9 located at the front end of the extrusion plate 8 are clamped in the ring groove at the outer end of the linkage ring 7, at this time, the positioning rubber ring 16 is wrapped in the sealing ring chamber, realizing stable and comprehensive connection between the hose joint and the one-way valve 2, avoiding leakage.

[0040] When a small amount of gas flows in the reverse direction, the one-way valve 2 is in a non-working state, and the gas can flow into the container valve from the metal woven rubber hose 4 through the manifold end 5, so as to start the container valve. When the container valve is opened to release high-pressure gas, the one-way valve 2 is in a working state, at this time, the gas can only flow in the forward direction (other high-pressure gas in the container cannot flow in the reverse direction), the gas in the container flows into the joint end, flows into the metal woven rubber hose 4 through the one-way valve 2, and finally flows to the manifold through the manifold end 5.
