Abstract

The invention discloses ethylene glycol water solution sealing liquid for a hydraulic pressure safety valve of an oil storing tank, and belongs to the field of sealing liquid. The sealing liquid is 6-70% by mass of ethylene glycol (CH2OH)2 water solution and is capable of decreasing the ice point to be less than -50 DEG C; the sealing liquid is high in boiling point, safe to use, free from oil, consistent in performances all the time, and hard to volatilize; materials are easy to obtain, and low in price; the sealing liquid is simple and convenient to prepare, daily operate and use; the set starting pressure of the hydraulic pressure safety valve is easily adjusted, so that the hydraulic pressure safety valve can act actually; in case of splashing, the sealing liquid is easily wiped up, sothat the sealing liquid is beneficial for industrial sanitation keeping; the working intensity of workers can be obviously reduced; and the cost is obviously decreased.

Description

technical field

[0001] The invention belongs to the field of sealing liquid, and is mainly applied in hydraulic safety valves of oil storage tanks. Background technique

[0002] According to the safety design requirements of oil storage and transportation, in order to reduce the loss of oil and gas and ensure the safe operation of the oil storage tank, two sets of breathing systems, a mechanical breathing valve and a hydraulic safety valve, must be installed on the top of the storage tank at the same time. The valve is in a normally closed state, or only the mechanical breathing valve is open to breathe, so as to reduce the escape of oil and gas as much as possible, and at the same time balance the pressure difference between the inside and outside of the oil storage tank to prevent the oil storage tank from expanding, deforming or being compressed by the atmosphere. The hydraulic safety valve is a safety backup device for the mechanical breathing valve, and its operating pr...
