Abstract
The utility model discloses a boiler safety device, which is used for monitoring the safety work of a boiler. The boiler safety device comprises a pressure measuring device for detecting the pressure of the boiler and a plurality of safety valves communicated with the boiler, wherein the pressure measuring device is connected with a pressure gauge, the pressure measuring device is connected with a controller, and the controller is connected with the safety valves. The boiler safety device disclosed by the utility model can select to open the appropriate safety valve according to the working pressure situation of the boiler, enable the boiler to achieve the standard working pressure as soon as possible, realize precision control, facilitate the use and ensure the safety work of the boiler.
Description
Technical field
The utility model relates to a kind of boiler component, relates in particular to a kind of safety device of boiler.
Background technology
Boiler is that the chemical energy with fuel is converted into heat energy, again with thermal energy transfer feedwater, vapour, heat conduction wet goods working medium, thereby produces steam, hot gas or the equipment through the heat-conducting work medium quantity of heat given up.Boiler is that entire society produces, life provides the energy and power, thereby is widely used.Safety valve is one of important safety annex on the boiler, and it plays an important role to the control of boiler internal pressure limit value and to the safeguard protection of boiler.Safety valve relies on the pressure of self to discharge the fluid of some, surpasses the predetermined safe value to prevent container or intrasystem pressure; After the pressure in the container recovered normally, valve was closed voluntarily, and organized medium to continue to discharge.But the control of safety valve is single now, can not make the boiler internal pressure recover normal sometimes as early as possible, and control is accurate inadequately.
The utility model content
The utility model technical problem to be solved provides a kind of boiler that can make as early as possible and reaches standard operation pressure, can precisely control again, and convenient the use guarantees the boiler safety device of trouble free service.
For solving the problems of the technologies described above; The technical scheme of the utility model is: boiler safety device; Be used to monitor the trouble free service of boiler, comprise the manograph and several safety valves that are communicated with boiler that are used to detect boiler pressure, said manograph is connected with Pressure gauge; Said manograph is connected with controller, and said controller connects said safety valve.
As optimized technical scheme, said safety valve by opening pressure setting value incremental manner successively or successively the mode of successively decreasing arrange.
As the improvement to technique scheme, said controller comprises central processing unit.
Owing to adopted technique scheme; Boiler safety device; Be used to monitor the trouble free service of boiler, comprise the manograph and several safety valves that are communicated with boiler that are used to detect boiler pressure, said manograph is connected with Pressure gauge; Said manograph is connected with controller, and said controller connects said safety valve.Operating pressure in the said manograph detection at any time boiler, and on said Pressure gauge, show force value, be convenient to the staff and observe; Simultaneously said manograph is delivered to said controller with detected boiler pressure, and when force value was excessive, said controller was controlled corresponding safety valve according to the opening pressure setting value of each safety valve and actual working pressure and carried out work; Safety valve by opening pressure setting value incremental manner successively or successively the mode of successively decreasing arrange; The stepped curved arrangement of opening pressure setting value of safety valve like this, when the pressure of boiler is excessive, the safety valve work that the opening pressure setting value is bigger; The operating pressure of boiler is recovered as early as possible; When the pressure of boiler exceeded standard a little, the safety valve work that the opening pressure setting value is less, control were accurately; The utility model is provided with several safety valves, according to the boiler working pressure situation, selects to open suitable safety valve, can make boiler return to standard operation pressure as early as possible, can precisely control again, and convenient the use guarantees trouble free service.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.In the detailed description below, some example embodiment of the utility model has only been described through the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation of spirit that does not depart from the utility model and scope, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
Shown in accompanying drawing, boiler safety device is used to monitor the trouble free service of boiler; Comprise the manograph and several safety valves that are communicated with boiler that are used to detect boiler pressure; Said manograph is connected with Pressure gauge, and said manograph is connected with controller, and said controller connects said safety valve.Said manograph detects the operating pressure in the boiler; And on said Pressure gauge, show force value; Being convenient to the staff observes; Simultaneously said manograph is delivered to said controller with detected boiler pressure, and when force value was excessive, said controller was controlled corresponding safety valve according to the opening pressure setting value of each safety valve and actual working pressure and carried out work.Said safety valve by opening pressure setting value incremental manner successively or successively the mode of successively decreasing arrange, the stepped curve setting of the opening pressure setting value of safety valve so not only is convenient to install to arrange; Simultaneously also be convenient to control safety valve, and when the pressure of boiler is excessive, the bigger safety valve work of controller control opening pressure setting value; The operating pressure of boiler is recovered as early as possible; When the pressure of boiler exceeds standard a little, the less safety valve work of controller control opening pressure setting value, control is accurately.Present embodiment is provided with several safety valves, according to the boiler working pressure situation, selects to open suitable safety valve, can make boiler return to standard operation pressure as early as possible, can precisely control again, and convenient the use guarantees trouble free service.
Said controller comprises central processing unit, and said central processing unit can be accurately compares the opening pressure setting value of boiler actual working pressure and safety valve standard setting, controls said safety valve work intelligently.And can adopt in the safety valve one or several to work simultaneously, said safety valve working forms is various, can be only one work independently, also can several work simultaneously, work is more suitable for practical application flexibly.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
