Safety valve assembly for remote liquid supply

Generally, the safety valve can be vented on the spot, and the vent should be more than 1 meter (m) above the operator and should not be directed to the open flame location, sparking location and high temperature equipment within 15 meters (m). The safety valve vents of indoor equipment and containers should be led out of the roof and should be more than 2 meters (m) above the roof.

When there is a block valve at the inlet of the safety valve, the block valve should be in a normally open state and be sealed with lead to avoid errors.

 (1) When there are gas and liquid two-phase materials in the container, the safety valve should be installed in the gas phase part.

 (2) When the safety valve is used to discharge flammable liquid, the outlet of the safety valve should be connected to the accident storage tank. When the discharged material is high-temperature combustible, its receiving container shall have corresponding protective facilities. The safety valve is a special valve that the opening and closing parts are in a normally closed state under the action of external force. When the pressure of the medium in the equipment or pipeline rises beyond the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. NOTE The safety valve must be pressure tested before it can be used. The diameter of the safety valve is generally not large, and the commonly used ones are between DN15mm-DN80mm, and those exceeding 150mm are generally called large-diameter safety valves. It is an indisputable fact that the market scale of the safety valve industry expanded in 2013. There are not many companies in my country that are qualified to produce safety valves, because safety valves belong to the special equipment industry. The State Administration of Quality Supervision is relatively strict in applying for qualification review, and the huge demand for safety valves in the market will undoubtedly give these qualified production safety. Valve businesses bring more opportunities for wealth.
