What Is the Risk of a Diesel Boiler When Crown Valve Is Closed

Industrial boiler is a device that uses the heat energy (or other heat energy) released by the combustion of fuel to heat the working medium to a certain parameter (temperature and pressure). The valves used in boilers are generally gate valves, ball valves, butterfly valves, safety valves, check valves and needle valves. Among them, in the boiler water system, it is a gate valve of medium and large diameter, in the steam system, it is a shut-off valve, and in the boiler ventilation flue gas system, a butterfly valve is used.

Safety valves are used on pressure equipment, containers or pipelines as overpressure protection devices. When the pressure in the equipment, container or pipeline rises above the allowable value, the valve automatically opens, and then discharges in full to prevent the pressure in the equipment, container or pipeline from continuing to rise; when the pressure decreases to the specified value, the valve Automatically shut down in time to protect the safe operation of equipment, containers or pipelines.

According to usage, it can be divided into the following categories:

1) Shut off the valve. Such as shut-off valve (ball valve), gate valve and cock, etc., mainly used to connect and cut off the medium in the pipeline.

2) Valve for adjustment. Such as throttle valve (ball valve), pressure regulating valve, water level regulator, etc., mainly used to adjust the flow, pressure, water level of the medium, etc., to adapt to the needs of different working conditions.

3) Valve for protection. Such as check valves, safety valves and quick shut-off valves. Among them, the check valve is used to automatically prevent the medium in the pipeline from flowing backwards; the safety valve is automatically opened when necessary to discharge excess media outward to prevent the media pressure from exceeding the specified value.
