Description
Technical Field
The utility model belongs to the technical field of oil safety warehousing and transportation, concretely relates to prevent spouting from retrieving hydraulic relief valve.
Background
The hydraulic safety valve is used as a common safety device of the petroleum storage tank, and the inside and the outside of the storage tank are isolated by liquid during operation. The working principle of the hydraulic safety valve is as follows: when the pressure in the tank is equal to the local atmospheric region, the liquid in the inner ring and the liquid in the outer ring are in the same plane; when the gas space in the tank is in positive pressure, the sealing liquid in the inner ring space is squeezed into the outer ring space by the gas pressure, and the liquid level is also changed when the pressure is continuously increased. When the liquid level in the space of the inner ring is level with the lower edge of the partition plate, the gas in the tank escapes to the atmosphere through the lower edge of the partition plate and the liquid in the outer ring, so that the pressure in the tank is not increased any more. When negative pressure is generated in the tank, sealing liquid in the outer ring space enters the inner ring space under the action of atmospheric pressure, and when the liquid level in the outer ring is level with the lower edge of the partition plate, the atmospheric air enters the tank through the liquid in the inner ring, so that the negative pressure in the tank is not increased any more. The lower edge of the partition board is made into a sawtooth shape, so that the sealing liquid is stable when flowing.
In the operation of the normal hydraulic pressure safety valve, the following four main problems exist:
first, when the instantaneous oil inlet amount of the storage tank increases, the sealing oil is sprayed out to be scattered on the top of the storage tank in order to maintain the balance of the internal and external pressures. Causing loss of sealing oil and causing a great deal of pollution.
Secondly, after the sealing oil is sprayed out, the sealing oil needs to be supplemented in time, and the production and operation cost is increased.
Thirdly, when the device operates in winter, the water in the crude oil is evaporated due to long-term heat tracing inside the storage tank, the water vapor rises to the top of the tank, the condensed water vapor reaches the space of the hydraulic safety valve and is mixed with the sealing oil to cause the sealing oil to be easy to deteriorate, and the freezing of the liquid vapor at low temperature causes the failure of the hydraulic safety valve, so that great potential safety hazards are brought to the operation of the storage tank.
Fourth, in order to ensure that the hydraulic safety valve operates normally in winter, the conventional solution only requires frequent equipment inspection and seal oil replacement.
At present, some units use antifreeze to replace sealing oil in winter, and the condensate mixed liquid cannot be frozen and blocked. But industry standards specify that the storage tank hydraulic safety valve standard: GB/T12243-2005 stipulates that oil products (such as light diesel oil, solar oil or transformer oil) with high boiling point (difficult volatilization in summer), slow evaporation and low condensation point (incapable of being solidified in winter) are used as sealing liquid (sealing liquid for short) in the valve, so that the used antifreezing solution does not meet the national standard.
The scene is in order to solve the hydraulic safety valve and has made in service the blowout of sealing oil and connect oil fill 5, but the effect is not good, still can take place a large amount of sealing oil and spill to the topping, causes the pollution, brings the smooth risk of falling in the topping operation for personnel moreover. And the control valve with the communication between the inside and the outside is manufactured for cleaning, but the structure requires that after the tank is poured every time, staff must go to the tank to manually open the valve to recover a part of overflowed sealing oil, so the use is inconvenient.
