The terms "comprising", "including", "having" and their variants mean "including but not limited to", unless otherwise specifically indicated.

[0029] Embodiment 1:

[0030] Referring to Figure 1 As shown in the figure, a quick-connection oil stop angle valve for fuel oil storage steel cylinders comprises a valve body 1, the valve body 1 comprises an installation input end 2, an output end, and a control end 3, the end of the output end is provided with a clamping joint 5, and the inside of the end is provided with a baffle 12, a through hole 13 is formed in the middle of the baffle 12, and the output end is provided with an elastic sealing assembly 6 for controlling the opening and closing of the through hole 13 in the baffle 12 on the side away from the clamping joint 5.

[0031] The installation input end 2 is used to install the angle valve on the steel cylinder, the output end is connected with the external oil supply pipeline, the control end 3 is the valve core of the angle valve, and the opening and closing of the angle valve are controlled, the clamping joint 5 is arranged at the end of the output end, so as to facilitate the connection with the external oil supply pipeline, the through hole 13 is formed in the baffle 12 inside, so as to enable the alcohol-based fuel oil to enter the oil supply pipeline from the through hole 13, and the elastic sealing assembly 6 is used to control the opening and closing of the through hole 13 according to whether the external oil supply pipeline is connected, when the joint of the external oil supply pipeline is separated from the clamping joint 5 of the angle valve, the elastic sealing assembly seals the through hole 13, so as to prevent the alcohol-based fuel oil remaining in the angle valve from leaking, when the joint of the external oil supply pipeline is connected with the clamping joint 5, the elastic sealing assembly 6 is separated from the through hole 13, so as to open the through hole 13, and thus the alcohol-based fuel oil can enter the external oil supply pipeline from the through hole 13.

[0032] This effectively avoids the need to replace the cylinder when the alcohol-based fuel oil in the cylinder is used up. At this time, the connector of the external oil supply line is separated from the clamp connector 5 of the angle valve on the cylinder. When the connector is removed from the clamp connector 5 on the angle valve, the through hole 13 can be closed in time. The alcohol-based fuel oil remaining in the angle valve cannot leak from the through hole 13, which will not affect the production environment and will not pose a safety hazard.

[0033] The elastic sealing assembly 6 includes a positioning seat 7, on which a positioning shaft 9 is provided. One end of the positioning shaft 9 is slidably connected to the positioning seat 7, and the other end is provided with a plug 10 that cooperates with the through hole 13. The plug 10 has a conical structure, with one end having a diameter smaller than the diameter of the through hole 13, and the other end having a diameter larger than the diameter of the through hole 13. The end with the larger diameter is connected to the positioning shaft 9. A return spring 18 is also sleeved on the positioning shaft 9. One end of the return spring 18 abuts against the plug 10, and the other end abuts against the positioning seat 7.

[0034] The positioning seat 7 is locked onto the inner wall of the output end of the valve body 1, while the plug 10 at the end of the positioning shaft 9 abuts against the through hole 13 of the baffle 12, sealing the through hole 13. The positioning shaft 9 is slidably connected to the positioning seat 7, so that the plug 10 will separate from the baffle 12 after being squeezed, thereby opening the through hole 13. The plug 10 moves towards the positioning seat 7. At this time, the positioning shaft 9 slides towards the positioning seat 7 along with the plug 10. The return spring 18 sleeved on the positioning shaft 9 retracts. When the connector of the external oil supply line is removed from the locking connector 5, the plug 10 is squeezed out of the connector. Under the elastic force of the return spring 18, the plug 10 moves towards the baffle 12, thereby sealing the through hole 13 on the baffle 12, thus preventing alcohol-based fuel oil from leaking from the through hole 13.

[0035] The plug 10 has a conical structure, which allows one end of the plug 10 to pass through the through hole 13, ensuring that the connector of the oil supply line can squeeze the plug 10, thereby opening the through hole 13 and ensuring that the angle valve can be opened.

[0036] The positioning seat 7 has a positioning sleeve 8 in the middle, and the positioning shaft 9 is slidably disposed in the positioning sleeve 8. The positioning seat 7 also has a guide hole 20, which is evenly distributed around the positioning sleeve 8.

[0037] The positioning shaft 9 slides inside the positioning sleeve 8, which improves the stability of the movement direction of the positioning shaft 9 during movement, thereby ensuring the stability of the plug 10 and ensuring that the plug 10 will not deflect, which would cause the plug 10 to fail to completely seal the through hole 13 and cause leakage.

[0038] The flow guide hole 20 facilitates the passage of alcohol-based fuel oil and prevents the positioning seat 7 from clogging the output end.

[0039] The elastic sealing assembly 6 is provided with a positioning member on the side away from the baffle 12, and the positioning member is a C-shaped elastic baffle 21.

[0040] The C-shaped elastic baffle 21 is abutted against the inner side wall of the output end of the valve body 1 under the action of its own elasticity, the elastic sealing assembly 6 is positioned by the C-shaped elastic baffle 21, and the elastic sealing assembly 6 is clamped in the output end.

[0041] The control end 3 is provided with a mounting hole 14 corresponding to the position of the output end, and the mounting hole 14 is threadedly connected with an end cap 15.

[0042] The elastic sealing assembly 6 and the positioning member are conveniently mounted in the output end of the valve body 1 through the mounting hole 14, and the mounting hole 14 is closed by the end cap 15, so that after the elastic sealing assembly 6 and the positioning member are mounted, the mounting hole 14 cannot be leaked by the alcohol-based fuel oil.

[0043] The inner side wall of the clamping head 5 is uniformly embedded with a plurality of ball plungers 16 in the radial direction.

[0044] The ball plunger 16 facilitates the insertion of the joint of the oil supply pipeline into the clamping head 5 of the output end, reduces the friction between the joint and the clamping head 5, prevents the joint from being damaged by long-term friction and being stably clamped in the clamping head 5, and prevents the leakage of alcohol-based fuel oil at the connection between the joint and the clamping head 5.

[0045] In use, the reset spring 18 is sleeved on the positioning shaft 9, and then the positioning shaft 9 is slidably connected with the positioning seat 7 to form an elastic sealing assembly. The elastic sealing assembly 6 is inserted into the output end through the mounting hole 14, the C-shaped elastic baffle 21 is placed into the output end from the mounting hole 14, and the C-shaped elastic baffle 21 is abutted against the positioning seat 7 to position and support the elastic sealing member. Then, the mounting hole 14 is closed by the end cap 15. The angle valve is connected to the steel cylinder through the mounting input end 2, and the angle valve is closed by the control end 3. The joint of the external oil supply pipeline is inserted into the clamping head 5, and the end of the joint is inserted into the clamping head 5 while extruding the plug 10, so that the plug 10 moves towards the positioning seat 7, the plug 10 is separated from the baffle 12, and the through hole 13 of the baffle 12 is opened. At this time, the steel cylinder of the angle valve is opened by the control end 3 to supply oil. When the alcohol-based fuel oil in the steel cylinder is used up, the steel cylinder needs to be replaced. At this time, the joint is taken out of the clamping head 5, the joint does not extrude the plug 10, the plug 10 returns to the initial position under the action of the elastic force of the reset spring 18, the plug 10 is inserted into the through hole 13 to close the through hole 13, and the alcohol-based fuel oil remaining in the angle valve cannot leak from the through hole 13, thereby effectively preventing the leakage of alcohol-based fuel oil and improving the safety of use. Since the alcohol-based fuel oil is mostly used in the kitchen, the pollution to the kitchen environment is effectively avoided, and the cleanliness of food is improved.
