Abstract

The invention provides a protection device of a boiler. The protection device comprises a controller, a temperature detector, an automatic adjusting valve, a liquid level detector, a pressure detector, an emptying valve and a safety adjusting valve, wherein the temperature detector, the liquid level detector and the pressure detector are in electric signal connection with a corresponding input end of the controller; the automatic adjusting valve and the emptying valve are connected with a corresponding output end of the controller; a valve hole is formed in the bottom of a valve body of the safety adjusting valve; a steam exhaust hole is formed in the side wall of the valve body of the safety adjusting valve; a limiting baffle plate is arranged at the upper end of an inner cavity of the valve body of the safety adjusting valve; the upper end of a valve rod penetrates through the limiting baffle plate; a valve core, which is propped against the steam exhaust hole, is arranged at the bottom of the valve rod in a sleeving manner; a spring is further arranged on the valve rod in a sleeving manner; the spring is arranged between the limiting baffle plate and the valve core; and a limiting rod horizontally penetrates through the side wall of the valve body and the upper end of the valve rod. According to the invention, the protection device has the advantages that the feedback and regulation are timely, the structure of a safety valve is simple, and the safety performance is high.

Description

technical field [0001] The invention belongs to the field of boiler safety control, and in particular relates to a boiler protection device. Background technique [0002] The boiler is a common energy equipment used in industrial production. During the operation of the boiler, the safety monitoring and control of the boiler is very important. In existing boilers, the automatic detection and control system is often not perfect, the feedback is not timely, and its safety control measures are relatively weak, especially the boiler safety valve as an important component of the boiler. The safety valve is used to control the pressure not to exceed the set value. It can play an important role in protecting personal safety and equipment operation. Common safety valves have various structures such as hammer type and spring type, which can be automatically adjusted according to the set pressure value. It is easy to cause problems such as accidental touch during operation. Content...
