Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery valves, and in particular to a high-safety oil and gas recovery valve. Background Technology

[0002] Oil and gas recovery valves enable tank trucks to achieve fully enclosed gas recovery during loading and unloading, limiting the emission of harmful gases into the atmosphere. In addition, the addition of a high-temperature shut-off function allows the valve to automatically close in high-temperature environments, ensuring the safety of the goods inside. With continuous technological advancements, the manufacturing processes for oil and gas recovery valves are becoming increasingly demanding.

[0003] Existing oil and gas recovery valves have certain drawbacks in use. Due to design limitations, the cylinders of current oil and gas recovery valves on the market are not very stable and can only be opened pneumatically, which is not conducive to use in various complex working conditions and brings certain adverse effects to the actual use process. Therefore, we propose a high-safety oil and gas recovery valve. Utility Model Content
