Description
Technical field
It is specifically a kind of to may be implemented in after positive/negative-pressure is opened through return pipe structure reality the present invention relates to Oil & Gas Storage field
The safe breather valve of fluid-tight of existing sealing fluid automatic back flow to inner cavity.
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 protective effect.Traditional deadweight safety valve is logical
It is normally placed 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 is by outside sealing fluid discharge van, when negative pressure is opened, sealing fluid is discharged into tank, to open in deadweight safety valve
Venting channels realize ventilation, and channel keeps long logical state to lose sealing function after sealing fluid is forced out outside valve or is discharged into tank,
Need manually to replenish sealing fluid, maintenance workload is huge.Meanwhile after partial loss occurs for sealing fluid in valve, traditional liquid
Pressing the cracking pressure of safety valve reduces, it is possible to open before opening prior to breather valve, cause the reduction of oil tank sealed pressure, cause
Leakage rate increases.Also, the sealing fluid of direct splash to petroleum storage tank top platform will lead to environmental pollution and cause safety and asks
Topic, the sealing fluid being discharged into tank can pollute storage medium in tank, also bring many inconvenience to the maintenance operation 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 reduction, 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.
