Description
Technical field
The utility model relates to a kind of explosion-proof malleation cabinet be applicable in the explosion risk environment such as petroleum and petrochemical industry, chemical industry, wine brewing, medicine, paint, weaving, printing and dyeing, military project facility, particularly relates to a kind of explosion-proof malleation cabinet without gas source temperature restriction.
Background technology
Along with the develop rapidly of the industry such as oil, chemical industry, the use of explosion-proof malleation cabinet in Systematical control is more and more extensive.But there is familiar lacunas in existing malleation cabinet, namely its inner electric elements can dispel the heat, and the heat retention of generation is inner at malleation cabinet, causes its temperature to raise, affect the normal work of electric elements, and high temperature alarm and course of work urgent interrupt can affect the serviceable life of electric elements frequently.Therefore, the electric elements negligible amounts of general explosion-proof malleation cabinet internal placement, this control ability that explosion-proof malleation cabinet is realized is less, and the inadaptable present age maximizes, intensive industrial demand.So, be necessary to improve the temperature adjuster system of explosion-proof malleation cabinet, design a kind of explosion-proof malleation cabinet without gas source temperature restriction.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, a kind of explosion-proof malleation cabinet without gas source temperature restriction provided, to meet the demand that a current malleation cabinet controls Multifunctional centralized reduction machinery and multistation machinery.
For achieving the above object, the technical solution adopted in the utility model is:
Without an explosion-proof malleation cabinet for gas source temperature restriction, it comprises automatic voltage regulating system and humidity control system; Described automatic voltage regulating system comprises alarm, pressure unit, pneumatic actuator, back-fire relief cap, pressure regulation filtrator; Humidity control system comprises pressure transducer, temp controlled meter, eddy current cooling tube; Described automatic voltage regulating system is arranged in explosion-proof malleation cabinet cabinet control chamber.
Described temp controlled meter is arranged on left and right malleation chamber front panel respectively.
Described pressure unit is arranged on control chamber front panel, and with temp controlled meter homonymy.
After adopting said structure, the beneficial effects of the utility model are:
1, this malleation cabinet has outside the high-touch features such as automatic air-exchanging, tonifying Qi, UHV (ultra-high voltage) releasing pressure automatically, low pressure alarming and the chain power-off of low pressure;
2, cabinet volume is large, and the separation of electrical equipment strong and weak electricity can prevent interfering with each other;
3, to the application of eddy current cooling tube, can lower the temperature to source of the gas (pressurized air), in the case of a high temperature, ventilation of frequently reporting to the police, to increase continuity, the stability of equipment to reduce gas in malleation cabinet.

Embodiment
The utility model provides a kind of explosion-proof malleation cabinet without gas source temperature restriction, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Usually the high precision control module (as: PLC module) of integrated more much thermal values and various discrete electronic devices and components in malleation cabinet, these precision elements work for a long time in hot environment, not only can premature aging, reduction of service life, and, once switch board internal temperature is too high, control accuracy and control stiffness will be had a strong impact on, even cause vigour part to burn, cause unexpected shut-down.To this, the utility model is by 2 kinds of method head it offs: 1) system alarm, starts automatic ventilation function and takes away unnecessary heat.2) humidity control system by introducing, directly regulates the instrument air temperature in whole system.
The utility model provides a kind of explosion-proof malleation cabinet without gas source temperature restriction specifically, and it comprises automatic voltage regulating system and humidity control system.
Automatic voltage regulating system comprises alarm, pressure unit, pneumatic actuator, ball valve, solenoid valve, back-fire relief cap, pressure regulation filtrator, throttling valve etc., in native system, by pressure regulation filtrator, ball valve, actuator, solenoid valve, throttling valve, back-fire relief cap etc., be installed in cabinet control chamber.Pressure unit shows malleation cavity pressure in real time, when pressure exceeds specialized range, and alarm equipment alarm, ball valve is opened automatically, and gas is discharged by back-fire relief cap, to reach step-down object; Otherwise ball valve is in closure state.
Further, pressure unit is arranged on control chamber front panel, and with temp controlled meter homonymy.
Humidity control system comprises alarm, pressure transducer, temp controlled meter, eddy current cooling tube etc.Alarm need be arranged on full position, directly over control chamber; Temp controlled meter is arranged on left and right malleation chamber front panel respectively.Temp controlled meter shows malleation cavity temperature in real time, and when temperature exceeds specialized range, alarm equipment alarm, system is regulated by air exchange system.Eddy current cooling is set in systems in which and reduces restriction user being inputted to barotropic gas temperature, reduce and frequently take a breath, enable this equipment in area application more widely, make this equipment have larger capacity setting height heat radiation electrical equipment simultaneously.
Vortex tube principle of work: the pressurized air with certain pressure expands after entering nozzle of vortex tube and accelerates, air-flow after accelerating enters a column type vortex generator, the air-flow rotated is with 1,000, the rotational speed of 000 rpm enters inside heat pipe along heat pipe wall, air-flow energy-producing separation after eddy current exchanges in heat pipe, air-flow is divided into two strands of air-flows---and one is thermal current, and another stock is cold airflow.In the terminal of heat pipe, part pressurized air is gushed in the mode of hot-air by variable valve, remaining pressurized air is to return by the center entering heat pipe swirling eddy compared with low velocity, and this strand of cold airflow is pooled to the discharge of cold air end by being formed centrally ultra-low temperature cold gas in generator.
The application of various valve and alarm, pressure transducer and temp controlled meter also makes described equipment also have multiple interlock protection function, and when whole system is in hypertonia or is too low, too high or too low for temperature, system can automatic cut-off power.
