Description
Technical field
The utility model relates to a kind of safety control system, relates in particular to a kind of still kettle main vapour valve safety control system.
Background technology
Along with the raising of the significance level of modern building and the continuous increase of building height; Bearing capacity to ground is had higher requirement, and subsoil can better not born the load that upper building transmits, so when using subsoil to put up building; A kind of processing mode of strengthening bearing capacity is arranged; Promptly use armored concrete to do the foundation pile of ground, with pile press machine stake being pressed into becomes foundation pile after underground, lets foundation pile top carry building.Piling as the foundation pile engineering is more on market, if any pile tube, all kinds of side stake, bored concrete pile, drilled pile etc.It is cylindric that pile tube is, and it is through the at a high speed rotation on centrifuge of centrifugal pile tube mould, makes in the pile tube mould concrete do the high speed centrifugation motion, is made into the concrete tubular pile of central zone circular hole at last.This technology is very ripe, has got into large-scale industrial production.China uses and has all stipulated corresponding standard for the design production of this type stake.For example " Code for design of building " (GB5007～2002) and " pretensioned prestressed concrete pipe pile " (GB13476～2009).In conjunction with the production of China's pretensioned prestressing pile tube and the situation of application, the pile tube behind centrifugal forming adopts maintaining process twice: once for atmospheric steam curing, once for autoclave curing (still kettle maintenance).
Employed still kettle when tube pile high-pressure steam curing at present; It is a kind of bulky, large pressurized vessel that weight is heavier; Length has 50 meters, and still kettle master steam supply valve is manually controlled by the still kettle operating personnel, when operation, can not see whether still kettle closes; Exist steam to leak, cause the crisis of operating personnel's actual bodily harm, affect the productivity effect of enterprise.
In sum, there is following shortcoming in prior art:
1, still kettle master steam supply valve is manually controlled by the still kettle operating personnel, when operation, can not see whether still kettle closes, and exists steam to leak, cause the crisis of personnel's actual bodily harm;
2, the steam productivity effect that leaks and form energy waste and influence enterprise.
The utility model content
The purpose of the utility model is to provide a kind of valve safety control system, and it is good to avoid opening by mistake of valve to open security performance, practices thrift the waste of the energy that leaks, and the personnel actual bodily harm of avoiding influences the productivity effect of enterprise.
For achieving the above object, the utility model provides a kind of still kettle main vapour valve safety control system, comprises still kettle, main vapour valve; Steam pipe; Also comprise: a sensor, said sensor is installed on the doorframe of said still kettle, is used for the closure state of sensing still kettle door; One controller, said controller electrically is connected with said sensor, is used for receiving and handling the information that said sensor transmits; One motor, said motor and said controller electrically connect, and the information that transmits when sensor is still kettle door when being in opening, and controller just transmits the indication of closing main vapour valve and gives motor, on the contrary controller then transmits the indication that opens main vapour valve and gives motor; Whether one safety cock, said safety cock are the elongated column, and said safety cock is connected with said electromechanics, and safety cock receives the indication action that motor provides, make the action of stretching out or packing up and control the still kettle main vapour valve and can open.
According to the described still kettle main vapour valve of the utility model preferred embodiment safety control system, said sensor is a piezoelectric transducer.
According to the described still kettle main vapour valve of the utility model preferred embodiment safety control system, said sensor is a photoelectric sensor.
Whether the still kettle main vapour valve safety control system of the utility model can safe opening through the control main vapour valve, improves production security, compared with prior art, the utlity model has following advantage:
1, it is good to avoid opening by mistake of valve to open security performance, practices thrift the waste of the energy that leaks, and has improved production efficiency;
2, avoid personnel's actual bodily harm the problem of security incident to occur, improved production security.

The specific embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1 and connect sketch map for a kind of still kettle main vapour valve of the utility model safety control system; Comprise still kettle 10, main vapour valve 60; Steam pipe 70; Also comprise: a sensor 20, said sensor 20 is installed on the doorframe of said still kettle 10, is used for the closure state of sensing still kettle door 11; One controller 30, said controller 30 electrically connects with said sensor 20, is used for receiving and handling the information that said sensor 20 transmits; One motor 40; Said motor 40 electrically connects with said controller 30; The information that transmits when sensor 20 is that still kettle door 11 is when being in opening; Controller 30 just transmits the indication that can not open main vapour valve 60 and gives motor 40, otherwise 30 transmission of controller can open the indication of main vapour valve 60 and give motor 40; Whether also have a safety cock 50, said safety cock 50 be the elongated column, and said safety cock 50 and said motor 40 mechanical connections, safety cock 50 receive the indication that motors 40 provide and move, make the action of stretching out or packing up and control main vapour valve 60 and can open.
The still kettle main vapour valve safety control system of the utility model, employed sensor 20 can be a piezoelectric transducer, or photoelectric sensor.Seeing also Fig. 2 is the utility model still kettle sketch map; Employed sensor 20 is installed on the doorframe of said still kettle 10, is used for the closure state that opens of sensing still kettle door 11.
See also the open sketch map of Fig. 3 for the utility model still kettle main vapour valve safety control system; Still kettle door 11 is in closing state, and sensor 20 sends to controller 30 with information after sensing still kettle door 11 closing state; After controller 30 was received, transmission can open the indication of main vapour valve 60 and give motor 40, and motor 40 is fixed on the support 80; Be in the top of main vapour valve 60; After motor 40 is received information, see through mechanical connecting structure the side of safety cock 50 towards motor shortened, up to surpassing more than the plane of main vapour valve 60; Leave in the main vapour valve 60, main vapour valve 60 can be rotated and open steam and inject still kettles with the autoclave curing pile tube through steam pipe 70; In this case, still kettle door 11 is in closing state, can rotate main vapour valve 60.
Fig. 4 is the sketch map of closing of the utility model still kettle main vapour valve safety control system.Men Wei is in closing state when still kettle, after then motor 40 is received information, sees through mechanical connecting structure safety cock 50 is extended towards the side away from motor 40; Up to the plane that surpasses main vapour valve 60, insert in the main vapour valve 60, play the purpose that stops main vapour valve 60 to rotate; In this case, the still kettle door is in the state that opens, and cannot rotate main vapour valve 60; Improved production security, consistent with the environment-friendly production process that country advocates.
More than the still kettle main vapour valve safety control system of the utility model has been carried out detailed introduction, compared with prior art, the utlity model has following advantage:
1, it is good to avoid opening by mistake of valve to open security performance, practices thrift the waste of the energy that leaks, and has improved production efficiency;
2, avoid personnel's actual bodily harm the problem of security incident to occur, improved production security.
More than the disclosed several specific embodiments that are merely the utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of the utility model.
