Abstract
The invention discloses a kind of expansion valves with heat insulating function, including expanding valve body, the expansion valve body is inserted in heat shield therein equipped with that will expand valve body, and the housing wall of the heat shield is equipped with door, the present invention using the above structure, has the following advantages：1, completely cut off the influence of Exhuster of engine and front deck heat radiation；2, when system can automatically open the door on heat shield when the temperature is excessively high in the gap between heat shield and expansion valve body, so that the gap between heat shield and expansion valve body and the space cross-ventilation on the outside of door, the temperature in heat shield is reduced in short time, then system control door is closed, if door opening time is long, Exhuster of engine and front deck heat radiation can not be completely cut off, increase the heat in heat shield instead, play minus effect.
Description
Technical field
The present invention relates to field of automobile air conditioner, more particularly to a kind of expansion valve with heat insulating function.
Background technology
The increasingly increase required for automobile ride comfort with client, automotive air-conditioning system stablize hair in performance
It waves and receives industry concern；Expansion valve experiences outlet temperature, adjusting refrigerant flow rate as the critical component in air-conditioning system
Function directly affects the performance of system performance；Ambient temperature can impact the system performance performance of expansion valve.
Invention content
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of isolation engine exhaust
The expansion valve with heat insulating function that device and front deck heat radiation influence.
In order to solve the above technical problems, the technical scheme is that：A kind of expansion valve with heat insulating function, including it is swollen
Swollen valve body, the expansion valve body, which is equipped with, will expand valve body and be inserted in heat shield therein.
The housing wall of the heat shield is equipped with door, and the door is opened/closed by controller control.
The inner walls of the heat shield are equipped with temperature sensor, and the temperature sensor is connect with controller.
It is equipped with gap between the inner wall and expansion valve body of the heat shield.
Temperature signal between the temperature sensor acquisition expansion valve body and heat shield in gap；
The controller, the temperature signal for being acquired according to temperature sensor, controls opening/closing for door.
Described heat shield one end is hatch frame, and the side wall of the heat shield is equipped with tube seat.
The expansion valve body is equipped with positioning pin, and the heat shield is equipped with the through-hole passed through for positioning pin, institute
The positioning pin stated is equipped with external screw thread, and nut is connected on positioning pin, is equipped between the nut and the outer wall of heat shield close
Gasket.
The present invention using the above structure, has the following advantages：1, completely cut off Exhuster of engine and the shadow of front deck heat radiation
It rings；2, when system can automatically open the door knot on heat shield when the temperature is excessively high in the gap between heat shield and expansion valve body
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 can not completely cut off engine exhaust dress if door opening time is long
It sets and front deck heat radiation, increases the heat in heat shield instead, play minus effect.
Description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments；
Fig. 1 is the decomposition texture schematic diagram of the present invention；
Fig. 2 is the structural schematic diagram of the present invention；
In Fig. 1~Fig. 2,1, expansion valve body；2, heat shield；3, door；4, tube seat；5, positioning pin；6, nut；7、
Gasket seal.
Specific implementation mode
A kind of expansion valve with heat insulating function as shown in Fig. 1~Fig. 2, including expansion valve body 1, expand on valve body 1
It is inserted in heat shield 2 therein equipped with valve body 1 will be expanded.The housing wall of heat shield 2 is equipped with door 3, and door 3 is by controlling
Device control opens/closes, and controller is the controller using air conditioning for automobiles.
The inner walls of heat shield 2 are equipped with temperature sensor, and temperature sensor is connect with controller.Heat shield 2 it is interior
It is equipped with gap between wall and expansion valve body 1.Temperature between temperature sensor acquisition expansion valve body and heat shield 2 in gap
Signal；Controller, the temperature signal for being acquired according to temperature sensor, controls opening/closing for door.Heat shield 2 one
End is hatch frame, and the side wall of heat shield 2 is equipped with tube seat 4.It expands valve body 1 and is equipped with positioning pin 5, heat shield 2 is equipped with
For the through-hole that positioning pin 5 passes through, positioning pin 5 is equipped with external screw thread, and nut 6, nut 6 and heat shield 2 are connected on positioning pin 5
Gasket seal 7 is equipped between outer wall.
A kind of application method of the expansion valve with heat insulating function, method include 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, positioning pin
Across through-hole and by nut check, there are gaps between heat shield and expansion valve body；
B) temperature sensor acquisition expands the temperature signal in gap between valve body and heat shield, and temperature is set higher than temperature
When value, controller controls door and opens, and when the opening duration reaches time setting value, controller controls door and closes.
Desired temperature is 40 degree, and time setting value is 30 seconds.
It is covered on outside expansion valve body 1 using heat shield 2, 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 increases, also can be to swollen
Swollen valve performance impacts.When system can automatically open when the temperature is excessively high in the gap between heat shield 2 and expansion valve body 1
Door 3 on heat shield 2 so that the space air in gap and 3 outside of door between heat shield 2 and expansion valve body 1
Convection current can avoid temperature height from impacting expansion valve performance to reduce the temperature in heat shield 2 in the short time in this way.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 instead, play
Minus effect.The technical scheme is that expansion valve is protected heat-insulated heat radiation with heat shield, at the same when expansion valve with every
Heat dissipation in the door short time when the temperature is excessively high, is opened in gap between heat cover, keeps expansion valve to be in a temperature lower
Environment.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as using the various improvement of technical scheme of the present invention progress, or not improved directly apply to other occasions
, within protection scope of the present invention.
