GYA hydraulic safety valve

Hydraulic safety valve is also called Y-type hydraulic safety valve. Y-type hydraulic safety valve is an important accessory installed on the top of the oil tank to protect the safety of the oil tank. When the mechanical breathing valve fails, the hydraulic safety valve can replace the mechanical breathing valve for exhaust or deflation.

The hydraulic safety valve is an important accessory installed on the top of the oil tank to protect the safety of the oil tank. When the mechanical breathing valve fails, the product can replace the mechanical breathing valve to exhaust or deflate.

The pressure or vacuum value controlled by the hydraulic safety valve is 10% higher than that of the mechanical breathing valve, so it will not operate under normal conditions. The valve uses oil with high boiling point (not easy to volatile in summer), slow evaporation, and low freezing point (not solidified in winter) (such as light diesel, solar oil or transformer oil) as the sealing liquid (referred to as the sealing liquid). This type of valve should generally be installed horizontally in the pipeline.

Hydraulic safety valve is a safety protection valve whose opening and closing parts are normally closed under the action of external force. When the pressure of the medium in the equipment or pipeline rises and exceeds the specified value, it will automatically open. It is prevented by discharging the medium to the outside of the system. The pressure of the medium in the pipeline or equipment exceeds the specified value. Safety valves belong to the category of automatic valves, which are mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, and it plays an important role in protecting personal safety and equipment operation. According to the opening height of the safety valve disc, it can be divided into a micro-lift type safety valve and a full-lift type safety valve. The opening stroke height of the micro-lift type safety valve is: ≤0.05d0 (**** discharge throat diameter); full-lift type The opening height of the safety valve is ≤0.25d0 (**** discharge throat diameter).

According to the opening height of the safety valve disc, it can be divided into a micro-lift safety valve and a full-lift safety valve. The opening stroke height of the micro-lift safety valve is: ≤0.05d0 (the smallest discharge throat diameter); full-lift safety The valve opening height is ≤0.25d0 (the smallest discharge throat diameter).

At present, the mass-produced safety valves are divided into two categories: spring type and rod type. There are also impulse hydraulic valves, pilot safety valves, safety switching valves, safety decompression valves, deadweight safety valves, etc. The spring-loaded safety valve mainly relies on the force of the spring to work. There are closed and unclosed spring-loaded safety valves. Generally, flammable, explosive or toxic media should be closed. Steam or inert gas can be unclosed. In the spring-loaded safety valve, there are also those with a wrench and without a wrench. The function of the wrench is mainly to check the flexibility of the valve disc, and sometimes it can also be used for manual emergency pressure relief. The lever type safety valve mainly relies on the force of the lever hammer to work, but the large size of the lever type safety valve often limits the selection Scope. Choose a safety valve with a radiator when the temperature is high.
