Abstract
The utility model discloses a power-plant high-pressure heater liquid level switch self-cooling device which comprises a gas source pipe, a hand-operated gas source stop valve, a filter relief-pressure valve, a solenoid valve, a liquid level switch, a temperature sensor, a positive-pressure side sampling pipe, a negative-pressure side sampling pipe, a positive-pressure side sampling valve, a negative-pressure side sampling valve, a signal cable and a controller. The temperature sensor is arranged on the liquid level switch. The gas source pipe, the hand-operated gas source stop valve, the filter relief-pressure valve, the solenoid valve and the liquid level switch are successively connected. The temperature sensor is connected with the controller through the signal cable. The controller is connected with the solenoid valve. As the temperature sensor, the solenoid valve and the filter relief-pressure valve are adopted in the power-plant high-pressure heater liquid level switch self-cooling device, adverse effect of excess temperature on equipment measurement and service life can be effectively overcome, reliability of switching signals can be ensured, service life of the switch is also raised. Thus, controllable online management of a high-pressure heater is realized.
Description
Technical field
The utility model relates to a kind of power plant high-pressure heater level switch auto-cool system.
Background technology
The high-pressure heater protection is one of power plant's main protection, so the reliability of high-pressure heater protection directly affects safe and stable operation and the economic benefit of electricity power enterprise, is the effective measures that reduce electricity power enterprise's unplanned property shutdown, improve the performance of enterprises.So require us to strengthen equipment reliability management, to break with the conventional idea, the science and technology of application of advanced, constantly improve protection system.High-pressure heater level switch accuracy of action and reliability, be directly connected to the reliability of high-pressure heater protection system.High-pressure heater level switch environment temperature of living in is too high, exceeds equipment and cable allowed band, easily causes the guard signal mistake to send out or refuse to send out, and can not guarantee the reliability of protection system.So it is the emphasis of high-pressure heater protection system that the temperature of high-pressure heater level switch is controlled.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can effectively overcomes the adverse effect of excess Temperature to device measuring and serviceable life; both guaranteed the reliability of switching signal; improve again the serviceable life of switch, thereby realize the controlled power plant's high-pressure heater level switch auto-cool system in the keyholed back plate reason of high-pressure heater protection system.
For addressing the above problem, the utility model adopts following technical scheme: a kind of power plant high-pressure heater level switch auto-cool system, comprise gas source pipe, manual source of the gas stop valve, filtering pressure reducing valve, solenoid valve, level switch, temperature sensor, malleation side stopple coupon, the suction side stopple coupon, malleation side sample valve, the suction side sample valve, signal cable and controller, described temperature sensor is arranged on level switch, described gas source pipe, manual source of the gas stop valve, filtering pressure reducing valve, solenoid valve is connected successively with level switch, temperature sensing is connected with controller by signal cable, described controller is connected with solenoid valve.
As preferably, described level switch is connected with malleation side stopple coupon, and described level switch is connected with the suction side stopple coupon.
As preferably, described malleation side sample valve is arranged on malleation side stopple coupon, and described suction side sample valve is arranged on the suction side stopple coupon.
The beneficial effect of the utility model power plant high-pressure heater level switch auto-cool system is: because described power plant high-pressure heater level switch auto-cool system has adopted temperature sensor, solenoid valve and filtering pressure reducing valve; have and can effectively overcome the adverse effect of excess Temperature to device measuring and serviceable life; both guaranteed the reliability of switching signal; improve again the serviceable life of switch, thereby realize the controlled advantage in the keyholed back plate reason of high-pressure heater protection system.
The accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model power plant high-pressure heater level switch auto-cool system.
Embodiment
Consult shown in Figure 1, a kind of power plant high-pressure heater level switch auto-cool system, comprise gas source pipe, manual source of the gas stop valve, filtering pressure reducing valve, solenoid valve, level switch, temperature sensor, malleation side stopple coupon, the suction side stopple coupon, malleation side sample valve, the suction side sample valve, signal cable and controller, described temperature sensor is arranged on level switch, described gas source pipe, manual source of the gas stop valve, filtering pressure reducing valve, solenoid valve is connected successively with level switch, temperature sensing is connected with controller by signal cable, described controller is connected with solenoid valve.
Described level switch is connected with malleation side stopple coupon, and described level switch is connected with the suction side stopple coupon, and described malleation side sample valve is arranged on malleation side stopple coupon, and described suction side sample valve is arranged on the suction side stopple coupon.
With power plant's high-pressure heater level switch of auto-cool system, a temperature sensor, manual source of the gas stop valve, filtering pressure reducing valve, solenoid valve and gas source pipe have been increased.The reload temperature sensor, opertaing device environment temperature of living in effectively, can establish upper temperature limit is 60 ℃, under be limited to 40 ℃, when temperature reaches 60 ℃, by the DCS system, carry out the logic judgement, send instruction, by the controller opens solenoid valve, make pressurized air enter level switch, from conduit, flow out again, heat in switch is taken away, level switch and cable environment temperature of living in is descended, when temperature is down to 40 ℃, by the DCS system, carry out the logic judgement, the controller shut electromagnetic valve, stopping pressurized air entering, prevent unnecessary source of the gas waste, thereby guarantee that temperature is controlled on the temperature of setting, between lower limit.Install filtering pressure reducing valve additional, can guarantee compressed-air actuated cleaning, prevent simultaneously hypertonia, affect accuracy and the reliability of high-pressure heater level switch measuring-signal.
The beneficial effect of the utility model power plant high-pressure heater level switch auto-cool system is: because described power plant high-pressure heater level switch auto-cool system has adopted temperature sensor, solenoid valve and filtering pressure reducing valve; have and can effectively overcome the adverse effect of excess Temperature to device measuring and serviceable life; both guaranteed the reliability of switching signal; improve again the serviceable life of switch, thereby realize the controlled advantage in the keyholed back plate reason of high-pressure heater protection system.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
