Abstract
The utility model discloses a driving controller based on a 4 DEG C water characteristic. The driving controller based on the 4 DEG C water characteristic belongs to the nuclear power station safety control technology field and is formed by fixing a piezoelectric conversion layer on a wall of a water receiver, connecting a piezoelectric piston with the piezoelectric conversion layer, and making the piezoelectric piston in series connection with a signal amplifier, a driving controller, a controlled device and a connection rod to form a loop. The driving controller based on the 4 DEG C water characteristic enables the water of 4 DEG C to be heated or cooled to generate a volume change when a system runs abnormally, employs the two approaches of electric signal control and connecting rod mechanical pushing combination to control an actuator of the controlled device, so that a passive control capability is achieved, and the safety of the system can be improved effectively.
Description
Technical field
The utility model belongs to nuclear plant safety opertaing device field.Be particularly related to a kind of driving governor based on 4 degrees centigrade of water characteristics.
Background technology
At present, equipment commonly used is controlled the difference by its power source, can be divided into pneumatic, hydrostatic transmission and electronic control.Along with the development of electromechanical integration and automatic technology, electronicly show huge advantage in commercial production, be applied to more and more in the on-the-spot and civilian automatic control system of Industry Control.Automatically control refer to utilize electronic, pneumatic, surge or the manpower such as Electromagnetic Drive beyond mode, equipment is controlled.Be characterized in: easy to use, safe; Can field control, also can far distance controlled; Can control single equipment, also can carry out centralized control to multi-section equipment; Can carry out simple switch and control, also can realize regulating and control; Coordinate robot calculator, can realize sequencing control.Due to remotely-controlled needs being arranged, device signal feedback-modulating signal or 4 ~ 20mA signal feedback generally all can be arranged, control in order to carry out equipment.The characteristics of hydraulic control system are to respond highlyer, and because hydraulic control system amount pressure can be very high, thereby the size of topworks is little, quality is also little; Because the liquid compression hydraulic spring stiffness is high, so the hydraulic pressure resonance frequency can be very high.The shortcoming of hydrostatic control is that real-time is not good.The vapour control has structure small and exquisite, and is easy for installation, the characteristics such as strong adaptability.But the environment temperature that adapts to and medium temperature are unsuitable too high.Electronic control is compared with pneumatic and hydrostatic transmission, and it has, and action response speed is fast, high efficiency, good speed adjustment features and the advantage such as easy and simple to handle.But it is Shortcomings also: such as complex structure, control accuracy is not enough, lacks perfect fault diagnosis, warning and treating apparatus.
The utility model content
The purpose of this utility model is to propose a kind of driving governor based on 4 degrees centigrade of water characteristics for the deficiency of prior art existence, it is characterized in that, fixing piezoelectricity conversion coating 2 on a wall of water receiver 1, piezo-piston 3 is connected with piezoelectricity conversion coating 2, piezo-piston 3 and signal amplifier 4. driving governor 5, controlled device 7 and connecting rod 6 are connected into the loop;
Described signal amplifier 4, driving governor 5 and connecting rod 6 all are placed in a camera bellows, carry out the processing of integration, are conducive to standardization and use.
The material of described reserve tank is the material of the thermal resistance of low thermal resistance, has good thermal conductivity as traditional copper, aluminium or the stainless steel capital, new material heat-conducting silicone grease, low thermal resistance pottery, conductive graphite sheet thermal conductivity are also fine in addition, also use morely at micromodule equipment, wall thickness is 1.5mm ~ 6.5mm, and this is conducive to the extraneous temperature variation of liquid impression.
The internal face in the same size of the size of described piezoelectricity conversion coating and piezo-piston is closely linked.
Described signal amplifier is positioned at the outside of reserve tank, and the weak voltage signals that is used for the piezoelectricity conversion coating is produced amplifies, and makes signal become suitable control signal.
Described driving governor is connected in the output of signal amplifier, its role is to start controlled device when receiving due to the caused piezoelectric signal of temperature variation, to guarantee security of system.
The beneficial effects of the utility model are to utilize the water of 4 degree be heated or cooled when abnormal running and produce volume change, adopt electric signal to control and the mechanical actuator that promotes two approach control controlled devices of combination of connecting rod, reach non-active control ability, can effectively improve Security of the system.
Description of drawings
Fig. 1 is the structural representation based on the driving governor of 4 degrees centigrade of water characteristics.
Embodiment
The utility model proposes a kind of driving governor based on 4 degrees centigrade of water characteristics.Be explained below in conjunction with accompanying drawing.
In the structural representation of driving governor based on 4 degrees centigrade of water characteristics shown in Figure 1, fixing piezoelectricity conversion coating 2 on a wall of water receiver 1, piezo-piston 3 is connected with piezoelectricity conversion coating 2, and the internal face in the same size of the size of piezoelectricity conversion coating and piezo-piston is closely linked.Piezo-piston 3 and signal amplifier 4. driving governor 5, controlled device 7 and connecting rod 6 are connected into the loop.
The utility model is to utilize to depart from the driving control device that 4 degrees centigrade of volume water become large principle.The high purity water of packing in water receiver 1, the size of water receiver is not less than: 10cm
3~ 1000cm
3The material of reserve tank is the material of the thermal resistance of low thermal resistance, has good thermal conductivity as traditional copper, aluminium or the stainless steel capital, new material heat-conducting silicone grease, low thermal resistance pottery, conductive graphite sheet thermal conductivity are also fine in addition, also use morely at micromodule equipment, wall thickness is 1.5mm ~ 6.5mm, and this is conducive to the extraneous temperature variation of liquid impression.when system normally moves, 4 degree water-mass densities diminish and produce volumetric expansion, cause piezoelectricity conversion coating 2 to produce voltage signal and promote piezo-piston 3, at this moment, piezo-piston 3 is transferred to signal amplifier 4 with voltage signal on the one hand, after voltage signal is processed through signal amplifier 4. be transferred to driving governor 5, driving governor 5 drives the actuator of controlled device 7, close or open controlled device 7, described signal amplifier is positioned at the outside of reserve tank, the weak voltage signals that is used for the piezoelectricity conversion coating is produced amplifies, make signal become suitable control signal, so that security of system is protected, piezo-piston 3 according to the volume change of reserve tank 1 interior water, promotes connecting rod 6 on the other hand, and connecting rod 6 acts on the actuator of controlled device 7, produces moment, and then opertaing device, reaches non-active control ability.Can effectively improve Security of the system.
