Background technique
Deadweight safety valve is the important accessory that storage tank safety is protected in oil movement and storage system, belongs to automatic valve class, state
Family's standard (SY/T 0511.2-2010 petroleum storage tank attachment part 2: deadweight safety valve) specifically describes conventional hydraulic safety
The primary structure and requirement of valve.Conventional hydraulic safety valve is used in conjunction with mechanical breather valve, and cracking pressure setting is higher than
Mechanical breather valve, therefore be not turned on when mechanical breather valve works normally, play the second defencive function.The safe breather valve of fluid-tight is usual
Setting is in roof, for realizing the respiratory function of oil tank instead of mechanical breather valve when mechanical breather valve breaks down.
The existing conventional hydraulic safety valve for containers such as oil tanks is opened due to internal structure setting in positive pressure
When, pressure inside the tank realizes ventilation for venting channels outside sealing fluid discharge van, are opened in deadweight safety valve, when sealing fluid is forced out valve
Channel keeps long logical state to lose sealing function after outer, needs manually to replenish sealing fluid, maintenance workload is huge.Meanwhile
After partial loss occurs for sealing fluid in valve, the cracking pressure of conventional hydraulic safety valve is reduced, it is possible to open prior to breather valve
It opens before, leads to the reduction of oil tank sealed pressure, leakage rate is caused to increase.Also, direct splash is to petroleum storage tank top platform
Sealing fluid will lead to environmental pollution and cause safety problem, also bring many inconvenience to the maintenance of petroleum storage tank system.
In conclusion conventional hydraulic safety valve is due to functional localization and reasons in structure, there are sealing fluid losses to cause to open
The problems such as pressure offset, maintenance is big, and operating status is unknown, environmental pollution.For conventional hydraulic safety valve major defect
Have patent pass through setting positive pressure hydrops slot and realize sealing fluid in such a way that trench bottom opens up several oil return holes valve in collect and
Reflux, but due to using venting channels as return flow line, cause sealing fluid and air-flow to mix entrainment, cannot fundamentally solve
Certainly sealing fluid loss and expulsion problem.
