Description

Technical Field

[0001] The utility model relates to the technical field of cylinder bottle angle valves, and particularly relates to a cylinder bottle angle valve with high durability and high sealing performance. Background Technique

[0002] A cylinder bottle angle valve is a valve installed on a gas cylinder, used to control the flow and blockage of the gas in the bottle. It controls the up and down movement of the valve core by rotating the valve stem, thereby realizing the on-off control of the gas. This valve is usually installed at the top of the gas cylinder and is a key connecting component between the gas cylinder and the using equipment.

[0003] For example, the Chinese patent discloses: A gas cylinder angle valve with an anti-filling structure, patent number: CN208535258U, which controls the one-way ventilation of the air outlet channel through an anti-filling valve, and then realizes the control of the intake of liquefied gas cylinders at the gas cylinder angle valve through the combination form of an on-off control component and an anti-filling valve, preventing illegal institutions from forcibly filling through the air outlet channel, effectively realizing the restricted filling of liquefied gas in liquefied gas cylinders, and thus improving the filling safety of liquefied gas cylinders.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: The above device controls the opening and closing of the valve body by rotating the handle. After a long time, the handle needs to be replaced due to impacts, abrasion, and environmental corrosion. However, the handle installation in the above device is usually relatively fixed and lacks a quick-release function. When disassembling and maintaining the handle, additional tools and time are required for disassembly, which affects the maintenance work efficiency. Content of the Utility Model

Specific implementation manners

[0026] In the embodiment of the present application, by providing a highly durable and highly sealed cylinder bottle angle valve, it effectively solves the problem that the above device controls the opening and closing of the valve body by rotating the handle. After a long time, due to the influence of bumps, wear, and environmental corrosion, the handle needs to be replaced. However, the handle installation in the above device is usually relatively fixed and lacks a quick-release function. When disassembling and maintaining the handle, additional tools and time are required for disassembly, which affects the maintenance work efficiency. When the handle body needs to be replaced after long-term use, the first sleeve is rotated counterclockwise. During the rotation of the first sleeve, the clamping force on the clamping block is released. After the first sleeve is completely screwed out, the handle body is lifted upward, and then it can be taken out for maintenance and replacement work. A new handle body is sleeved outside the valve stem, and the first sleeve is rotated clockwise. The inclined extrusion groove contacts the clamping block. During the rotation of the first sleeve, the clamping block is squeezed to rotate around the round rod. Through the rotation of the clamping block and the engagement with the card slot, the handle body is clamped and fixed. By screwing the first sleeve, the replacement and installation of the handle body can be completed. The operation is simple and convenient, avoiding the need to replace the entire angle valve body due to the inability to disassemble the handle body, which is beneficial to extending the service life of the angle valve body and improving the durability of the angle valve body.

[0031] In view of the problems existing in the prior art, the present utility model provides a high-durability and high-sealing cylinder bottle angle valve. When the handle body 16 needs to be replaced after long-term use, the first sleeve 15 is screwed counterclockwise. During the rotation of the first sleeve 15, the clamping block 14 is released from the pressing force. After the first sleeve 15 is completely screwed out, the handle body 16 is lifted upward, and it can be taken out for maintenance and replacement work. A new handle body 16 is sleeved outside the valve stem 19, and the first sleeve 15 is screwed clockwise. The inclined extrusion groove 18 contacts the clamping block 14. During the rotation of the first sleeve 15, the clamping block 14 is squeezed to rotate around the round rod 13.

The replacement and installation of the handle body 16 can be completed by screwing the first sleeve 15. The operation is simple and convenient, avoiding the need to replace the entire angle valve body 11 due to the inability to disassemble the handle body 16, which is beneficial to extending the service life of the angle valve body 11 and improving the durability of the angle valve body 11.

[0032] Working principle:

[0033] First step, connect the connecting pipe 23 to the cylinder bottle. After the connection is completed, the connecting pipe 23 is sleeved into the connection port 21. The handle body 16 is sleeved outside the valve stem 19. Hold and screw the handle body 16. The handle body 16 drives the valve stem 19 to rotate. By rotating the valve stem 19, the valve core is controlled to move up and down to control the flow and blockage of the gas.

[0034] Step 2, when the handle body 16 needs to be replaced after long-term use, counterclockwise rotate the first sleeve 15. During the rotation of the first sleeve 15, the clamping block 14 is released from being pressed tightly. After the first sleeve 15 is completely screwed out, lift the handle body 16 upward, and it can be taken out for maintenance and replacement work. Put the new handle body 16 on the outside of the valve stem 19, and rotate the first sleeve 15 clockwise. The inclined extrusion groove 18 contacts the clamping block 14. During the rotation of the first sleeve 15, the clamping block 14 is extruded to rotate around the round rod 13. Through the rotation of the clamping block 14, it fits with the clamping groove 17, and then the handle body 16 is clamped and fixed. By screwing the first sleeve 15, the replacement and installation of the handle body 16 can be completed. The operation is simple and convenient, avoiding the need to replace the entire angle valve body 11 due to the inability to disassemble the handle body 16, which is beneficial to extending the service life of the angle valve body 11 and improving the durability of the angle valve body 11. When the connecting pipe 23 is installed, put the sealing ring 25 on the outside of the connecting pipe 23. After the sealing ring 25 is installed, insert the connecting pipe 23 into the connecting port 21, and rotate the second sleeve 24. The second sleeve 24 is threadedly connected to the outside of the external thread 22, and the connecting pipe 23 is installed and fixed through the second sleeve 24. After the connecting pipe 23 is fixed, the sealing ring 25 is located in the round groove 26, and its position is limited to ensure the fixed installation position of the sealing ring 25 and ensure a tight fit, which is beneficial to improving the sealing performance.
