①closed safety valve body pressure intensity test should be done. The test pressure is 1.5 times of the rated working pressure of the system. ② safety valve should be air tightness test, the test pressure system rated working pressure. ③ safety valve takeoff pressure by the system rated working pressure 1. Post-t. 1 times the adjustment, the adjustment of the gas should be inert gas such as air or nitrogen; When the compressor medium containing flammable and explosive gases, the general does not allow the compressor system is running with the working gas for safety valve adjustment o When the system Working pressure exceeds 30MPa, it is best to set two safety valves o ⑤ due to corrosion, import pipe fouling caused by heat and other causes of safety valve stuck can not take off or can take off but not tight after the release of relief valve should be carried out Check, repair, check or replace. ⑥ safety valve spool and valve seat should be carefully ground with each other to ensure its airtightness. Coarse grinding, the special carcass can be used to adhere to the emery cloth, respectively, eagle ball valve seat and seat, can shorten the rent grinding time.
Gasoline SUVs are sport utility vehicles powered by internal combustion engines running on gasoline. They offer spacious seating for up to 7 passengers and are designed for versatile transportation needs.
The main advantage of Gasoline SUVs over electric cars lies in their well-established infrastructure and widespread availability of fueling stations, providing convenience for long-distance travel and reducing charging concerns. Gasoline SUVs also typically have a longer driving range compared to some early Electric SUV models, making them suitable for extended journeys.
Furthermore, fuel-efficient 7-passenger SUVs are designed to optimize fuel consumption, offering a balance between performance and efficiency. Low fuel consumption SUVs help reduce the overall cost of ownership and are a budget-friendly option for many drivers.
