The inner walls of heat shield be provided with temperature sensor, described temperature sensor is connected with controller, described heat shield
Inwall and expansion valve body between be provided with gap, the collection of described temperature sensor expands gap between valve body and heat shield
Interior temperature signal；Described controller, for the temperature signal gathered according to temperature sensor, control the opening of door/
Close, described heat shield one end is hatch frame, and the side wall of described heat shield is provided with tube seat, described expansion valve body
Alignment pin is provided with, described heat shield is provided with the through hole passed through for alignment pin, and described alignment pin is provided with external screw thread, fixed
Nut is connected with the pin of position, gasket seal is provided between described nut and the outer wall of heat shield, it is characterised in that：
Described method comprises the following steps：
A) heat shield is covered on expansion valve body, expands the tube seat that the pipeline on valve body passes through heat shield, alignment pin
Through through hole and by nut check, gap is left between heat shield and expansion valve body；
B) temperature sensor collection expands the temperature signal in gap between valve body and heat shield, and temperature is set higher than temperature
During value, controller control door is opened, and when the opening duration reaches time setting value, controller control door is closed.
Described desired temperature is 40 degree, and described time setting value is 30 seconds.
The present invention uses the above method, has advantages below：1st, Exhuster of engine and the shadow of front deck heat radiation are completely cut off
Ring；2nd, when temperature is too high in the gap between heat shield and expansion valve body, system can automatically open up the door knot on heat shield
Structure so that the gap between heat shield and expansion valve body and the space cross-ventilation on the outside of door, reduce in the short time every
Temperature in heat cover, then system control door closing, if door opening time is long, engine exhaust dress can not be completely cut off
Put and front deck heat radiation, increase the heat in heat shield on the contrary, play minus effect.
Brief description of the drawings

Fig. 2 is the structural representation of expansion valve in the present invention；
In Fig. 1~Fig. 2,1, expansion valve body；2nd, heat shield；3rd, door；4th, tube seat；5th, alignment pin；6th, nut；7、
Gasket seal.
Embodiment
A kind of application method of expansion valve as shown in Fig. 1~Fig. 2, the expansion valve with heat insulating function include expansion valve body
1, expansion valve body 1 is provided with is inserted in heat shield 2 therein by expansion valve body 1.The housing wall of heat shield 2 is provided with door
3, door 3 beats opening/closing by controller control, and controller is the controller using air conditioning for automobiles.
The inner walls of heat shield 2 are provided with temperature sensor, and temperature sensor is connected with controller.Heat shield 2 it is interior
Gap is provided between wall and expansion valve body 1.Temperature between temperature sensor collection expansion valve body and heat shield 2 in gap
Signal；Controller, for the temperature signal gathered according to temperature sensor, control door beats opening/closing.Heat shield 2 one
Hold and be provided with tube seat 4 for hatch frame, the side wall of heat shield 2.Expansion valve body 1 is provided with alignment pin 5, and heat shield 2 is provided with
The through hole passed through for alignment pin 5, alignment pin 5 are provided with external screw thread, and nut 6, nut 6 and heat shield 2 are connected with alignment pin 5
Gasket seal 7 is provided between outer wall.
Method comprises the following steps：
A) heat shield is covered on expansion valve body, expands the tube seat that the pipeline on valve body passes through heat shield, alignment pin
Through through hole and by nut check, gap is left between heat shield and expansion valve body；
B) temperature sensor collection expands the temperature signal in gap between valve body and heat shield, and temperature is set higher than temperature
During value, controller control door is opened, and when the opening duration reaches time setting value, controller control door is closed.
Desired temperature is 40 degree, and time setting value is 30 seconds.
Covered on using heat shield 2 outside expansion valve body 1, it is therefore an objective to completely cut off Exhuster of engine and front deck heat radiation.But
It is that the time more long afterwards, expands atmosphere draught-free in the gap between valve body 1 and heat shield, and temperature slowly raises, also can be to swollen
Swollen valve performance impacts.When temperature is too high in the gap between heat shield 2 and expansion valve body 1, system can automatically open up
Door 3 on heat shield 2 so that the space air in gap and the outside of door 3 between heat shield 2 and expansion valve body 1
Convection current, so to reduce the temperature in heat shield 2 in the short time temperature height can be avoided to impact expansion valve performance.Men Jie
The time that structure is opened is 30 seconds, and then system control door 3 is closed, and the opening time of door 3 is unsuitable long, if door
3 opening times are long, can not completely cut off Exhuster of engine and front deck heat radiation, increase the heat in heat shield 2 on the contrary, play
Minus effect.The technical scheme is that expansion valve protected into heat-insulated heat radiation with heat shield, at the same when expansion valve with every
When the temperature in gap is too high between heat cover, opens in the door short time and radiate, keep expansion valve to be in a temperature relatively low
Environment.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employing the various improvement of technical scheme progress, or not improved directly apply to other occasions
, within protection scope of the present invention.
