Technical field
The utility model relates to a kind of solenoid valves with cooling heat radiator.
Background technique
Solenoid valve product at work, has the case where electromagnetic valve coil generates heat, and typically results in electromagnetic valve coil hair
The reason of heat is caused by the electromagnetic valve work time is longer.Solenoid valve product has normally opened and normally closed two kinds of forms, if user makes
Normally closed solenoid valve, and if real work when it is normally opened, this easily causes the coil of solenoid valve to overheat.If electric
The coil of magnet valve is equipped with energy-saving protective module (effect of energy-saving module is energy conservation and the cooling of electromagnetic valve coil), when this energy conservation
When protective module failure problem, the fever of coil is also resulted in, such as application No. is 201720614107.4 Chinese patents.
The besides actual working environment of solenoid valve, more than the working environment range of solenoid valve product design.Such as environment temperature and Jie
The problems such as matter temperature is excessively high or pressure is excessive and supply voltage.It will affect electromagnetism if electromagnetic valve work temperature is excessively high
The working efficiency of valve even damages solenoid valve components.
The Steam Turbine tripping electromagnetic valve of big power station is long-term electrification solenoid valve, and solenoid valve charges will necessarily lead for a long time
Induced coil long-term fever, this will reduce the service life of solenoid valve and control precision, cause Steam Turbine to trip when serious.Separately
The outer solenoid valve close to heat supply pipeline can lead to solenoid valve long-term fever because environment temperature is excessively high, also result in solenoid valve use
Service life reduction influences the safety problem during heat supply.
Solution to the problems described above is to install solenoid valve additional radiator.The solenoid valve for installing radiator additional can make heat
It removes as early as possible, prevents solenoid valve from charging fever for a long time, avoid Steam Turbine tripping or extraction steam pipe caused by damaging because of solenoid valve
Road valve solenoid valve power loss and it is out of hand.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and it is reasonable to provide a kind of design
Solenoid valve with cooling heat radiator.
The technical scheme in the invention for solving the above technical problem is: a kind of solenoid valve with cooling heat radiator,
It is characterised in that it includes radiating fin, thermal grease layer, solenoid valve body, power supply line, switch and power supply；The radiating fin
It is fixed in solenoid valve body, the thermal grease layer is coated between solenoid valve body and radiating fin, the power supply line
One end is connect with solenoid valve body, and the other end of the power supply line is connected with switch, and the switch connects to power supply.Pass through the band
The solenoid valve of cooling heat radiator can prevent solenoid valve body from charging fever for a long time, avoid vapour caused by damaging because of solenoid valve
Take turns unit tripping or extraction line valve solenoid valve power loss and out of hand.
Furthermore, the material of the radiating fin is ceramics.Ceramic thermal capacity is small, not accumulation of heat itself is directly radiated,
" hot ladder " will not be formed as metal fin, influence to radiate；The structure of ceramic Micro-v oid itself, substantially increase with
The heat dissipation area of air contact greatly strengthens heat dissipation effect, and year-on-year condition, under natural convection, heat dissipation effect is than super
Copper, aluminium, under closed environment, active heat loss through radiation ability is 8.8 times of metal material, and heat dissipation advantage is more obvious；Ceramics itself are exhausted
Edge, high temperature resistant, anti-oxidant, acid and alkali-resistance, cold-resistant thermal shock, thermal expansion coefficient are low, ensure that in high and low temperature environment or other evils
The stability of ceramic radiating fin under bad environment；Ceramics be resistant to high current, it is high pressure resistant, can leakproof electrical breakdown, without noise, Bu Huiyu
Other power tubes generate coupling parasitic capacitance, and therefore simplify filtering；Required creepage distance is shorter than what metallic object required,
Arrangement space is further saved, the more conducively design of engineer passes through with what is electrically authenticated；Ceramics can effectively it is anti-tampering, resist it is quiet
Film is rung, and the moisture absorption, dust-proof, does not influence its effect；Ceramic volumetric is small, light-weight, does not take up space, and saves materials, saves freight charges,
It is more advantageous to the rational deployment of product design；Ceramics belong to inorganic material, more meet environmental requirement.
Furthermore, the material of the thermal grease layer is organic material heat-conducting silicone grease.Organic silicon grease material, Ji Huyong
Do not solidify far, can -50 DEG C -+230 DEG C at a temperature of for a long time keep use when fat state.Both there is excellent electrical isolation
Property, and have excellent thermal conductivity, while having low oily from degree (being intended to zero), high-low temperature resistant, water-fast, ozone, weather-resistant；
Manufactured heat-conducting type organosilicon smectic compound, for thermally conductive between thermally conductive fin and solenoid valve and heat dissipation, to guarantee solenoid valve
The stabilization of performance.
Furthermore, the radiating fin includes multiple, and multiple radiating fins are equally spaced.
The installation method of the above-mentioned solenoid valve with cooling heat radiator is as follows:
Step 1: radiating fin is fixed on solenoid valve body surface；
Step 2: being applied to heat-conducting silicone grease is full and uniform between radiating fin and solenoid valve body；
Step 3: one end of power supply line is connect with solenoid valve body；
Step 4: switch is connected with the other end of power supply line；
Step 5: power supply is connected with switch.
The utility model compared with prior art, has the following advantages that and effect:
1, solenoid valve uses the thermally conductive fin of ceramic material, solenoid valve can be made to generate using the microstructure of ceramics
Heat quickly removes.
2, using organic heat-conducting silicone grease, material almost never solidifies, can -50 DEG C -+230 DEG C at a temperature of protect for a long time
