Abstract
The invention discloses a kind of expansion valve with heat insulating function, including expansion valve body, described expansion valve body is provided with and expansion valve body is inserted in heat shield therein, the housing wall of described heat shield is provided with door, the present invention uses said structure, has the advantage that 1, isolation Exhuster of engine and the thermal-radiating impact of front deck；2, when in the gap between heat shield and expansion valve body, temperature is too high, system can automatically open up the door on heat shield, make the gap between heat shield and expansion valve body and the space cross-ventilation outside door, the temperature in heat shield is reduced in short time, then system controls door closedown, if door opening time is long, Exhuster of engine and front deck heat radiation cannot be completely cut off, increase the heat in heat shield on the contrary, play minus effect.
Description
Technical field
The present invention relates to field of automobile air conditioner, particularly to a kind of expansion valve with heat insulating function.
Background technology
The increase day by day required for automobile ride comfort with client, stablizing in performance sends out automotive air-conditioning system
Wave and enjoy industry to pay close attention to；Expansion valve is as the critical component in air conditioning system, and it experiences outlet temperature, adjusting refrigerant flow rate
Function, directly affects the performance of systematic function；The systematic function performance of expansion valve can be impacted by ambient temperature.
Summary of the invention
The technical problem to be solved is, for the deficiencies in the prior art, it is provided that a kind of isolation engine exhaust
Device and the expansion valve with heat insulating function of front deck heat radiation impact.
For solving above-mentioned technical problem, the technical scheme is that a kind of expansion valve with heat insulating function, including swollen
Swollen valve body, described expansion valve body is provided with and expansion valve body is inserted in heat shield therein.
The housing wall of described heat shield is provided with door, and described door is controlled to beat opening/closing by controller.
The inner walls of described heat shield is provided with temperature sensor, and described temperature sensor is connected with controller.
It is provided with gap between inwall and the expansion valve body of described heat shield.
Described temperature sensor gathers the temperature signal between expansion valve body and heat shield in gap；
Described controller, for the temperature signal gathered according to temperature sensor, control door beats opening/closing.
Described heat shield one end is hatch frame, and the sidewall of described heat shield is provided with tube seat.
Described expansion valve body is provided with alignment pin, and described heat shield is provided with the through hole passed for alignment pin, institute
The alignment pin stated is provided with external screw thread, and alignment pin connects nut, is provided with close between described nut and the outer wall of heat shield
Gasket.
The present invention uses said structure, has the advantage that 1, isolation Exhuster of engine and the thermal-radiating shadow of front deck
Ring；2, when in the gap between heat shield and expansion valve body, temperature is too high, system can automatically open up the door knot on heat shield
Structure so that reduce in the space cross-ventilation outside the gap between heat shield and expansion valve body and door, short time every
Temperature in heat cover, then system controls door closedown, if door opening time is long, it is impossible to isolation engine exhaust dress
Put and front deck heat radiation, increase the heat in heat shield on the contrary, play minus effect.

Detailed description of the invention
A kind of expansion valve with heat insulating function as shown in Fig. 1～Fig. 2, including expansion valve body 1, on expansion valve body 1
It is provided with and expansion valve body 1 is inserted in heat shield 2 therein.The housing wall of heat shield 2 is provided with door 3, and door 3 is by controlling
Device controls to beat opening/closing, and controller i.e. uses the controller of air conditioning for automobiles.
The inner walls of heat shield 2 is provided with temperature sensor, and temperature sensor is connected with controller.Heat shield 2 interior
It is provided with gap between wall and expansion valve body 1.Temperature sensor gathers the temperature between 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
End is hatch frame, and the sidewall of heat shield 2 is provided with tube seat 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 nut 6, nut 6 and heat shield 2
Gasket seal 7 it is provided with between outer wall.
A kind of using method of the expansion valve with heat insulating function, method comprises the following steps:
A) being covered on by heat shield on expansion valve body, the pipeline on expansion valve body is through the tube seat of heat shield, alignment pin
Through through hole and by nut check, between heat shield and expansion valve body, leave gap；
B) temperature sensor gathers the temperature signal in gap between expansion valve body and heat shield, and temperature sets higher than temperature
During value, controller controls door and opens, and opens the persistent period when reaching time setting value, and controller 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
It is that the time, atmosphere draught-free in the gap between expansion valve body 1 and heat shield, temperature slowly raised, also can be to swollen more long afterwards
Swollen valve performance impacts.When in gap between heat shield 2 and expansion valve body 1, temperature is too high, system can automatically open up
Door 3 on heat shield 2 so that the gap between heat shield 2 and expansion valve body 1 and the space air outside door 3
Convection current, so can reduce the temperature in heat shield 2, it is to avoid expansion valve performance is impacted by temperature height in the short time.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, it is impossible to isolation 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 and with heat shield expansion valve protected insulation thermal radiation, simultaneously when expansion valve with every
When the temperature in gap is too high between heat cover, opens heat radiation in the door short time, keep expansion valve to be in a temperature relatively low
Environment.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way
Restriction, as long as have employed the various improvement that technical scheme is carried out, or the most improved directly apply to other occasion
, all within protection scope of the present invention.
