Detailed description of the invention
The using method of a kind of expansion valve as shown in Fig. 1～Fig. 2, the expansion valve with heat insulating function includes expanding
Valve body 1, expansion valve body 1 is provided with and expansion valve body 1 is inserted in heat shield 2 therein.Heat shield 2
Housing wall be provided with door 3, door 3 by controller control beat opening/closing, controller i.e. uses vapour
The controller of car air-conditioning.
The inner walls of heat shield 2 is provided with temperature sensor, and temperature sensor is connected with controller.Heat insulation
It is provided with gap between inwall and the expansion valve body 1 of cover 2.Temperature sensor gathers expansion valve body with heat insulation
Temperature signal in gap between cover 2；Controller, for the temperature signal gathered according to temperature sensor,
Control door beats opening/closing.Heat shield 2 one end is hatch frame, and the sidewall of heat shield 2 is provided with pipe
Groove 4.Expansion valve body 1 is provided with alignment pin 5, and heat shield 2 is provided with the through hole passed for alignment pin 5,
Alignment pin 5 is provided with external screw thread, and alignment pin 5 connects a nut 6, the outer wall of nut 6 and heat shield 2 it
Between be provided with gasket seal 7.
Method comprises the following steps:
A) being covered on by heat shield on expansion valve body, the pipeline on expansion valve body passes the tube seat of heat shield,
Alignment pin, through through hole and by nut check, leaves gap between heat shield and expansion valve body；
B) temperature sensor gathers the temperature signal in gap between expansion valve body and heat shield, and temperature is higher than temperature
During degree setting value, controller controls door and opens, and opens the persistent period when reaching time setting value, controls
Device controls door and cuts out.
Desired temperature is 40 degree, and time setting value is 30 seconds.
Heat shield 2 is used to cover on outside expansion valve body 1, it is therefore an objective to isolation Exhuster of engine and front deck heat
Radiation.But, the time more long afterwards, atmosphere draught-free in the gap between expansion valve body 1 and heat shield,
Temperature slowly raises, and also can impact expansion valve performance.Between heat shield 2 and expansion valve body 1
Gap in temperature too high time system can automatically open up the door 3 on heat shield 2 so that heat shield 2 with
Gap between expansion valve body 1 and the space cross-ventilation outside door 3, so can be in the short time
Reduce the temperature in heat shield 2, it is to avoid expansion valve performance is impacted by temperature height.Door open time
Between be 30 seconds, then system controls door 3 and closes, and the opening time of door 3 is unsuitable long, if door
Structure 3 opening time is long, it is impossible to isolation Exhuster of engine and front deck heat radiation, increases heat insulation on the contrary
Heat in cover 2, plays minus effect.The technical scheme is that and with heat shield, expansion valve is protected
Insulation thermal radiates, and when the temperature in gap is too high between expansion valve and heat shield simultaneously, opens door in short-term
Interior heat radiation, keeps expansion valve to be in a relatively low environment of temperature.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by upper
State the restriction of mode, as long as have employed the various improvement that technical scheme is carried out, or the most improved directly
Scoop out for other occasion, all within protection scope of the present invention.
