Abstract
The invention discloses a kind of expansion valve assembly, including expansion valve body, described expansion valve body is provided with throttle orifice, and the sidewall of described expansion valve body is provided with by-pass prot.The present invention uses said structure, have the advantage that the by-pass prot by expansion valve, when high speed coolant is by by-pass prot, utilize contacting of spheroid and chamfering, when high speed coolant is by valve body, increasing circulation area, make more cold-producing medium by valve body, the whistle sound etc. making coolant flow can eliminate automatically.
Description
Technical field
The present invention relates to expansion valve of automobile air conditioner technical field, particularly to a kind of expansion valve assembly.
Background technology
Along with the requirement of energy-conserving and environment-protective is more and more higher, cost performance is more and more higher, and the efficiency requirements of compressor of air conditioner is increasingly
Height, the comfortableness of car load is more and more higher！The air conditioning system brought therewith through expansion valve throttle orifice, the air-flow sound of institute's product,
The most increasingly it is taken seriously！Air-flow sound is not played good current stabilization reducing effect by traditional expansion valve.
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 expansion valve assembly, to reach
To the purpose reducing noise.
For solving above-mentioned technical problem, the technical scheme is that a kind of expansion valve assembly, including expansion valve body,
Described expansion valve body is provided with throttle orifice, and the sidewall of described expansion valve body is provided with by-pass prot.
Described by-pass prot and the intrinsic spherical intracavity inter-connection of expansion valve.
Described throttle orifice and the intrinsic spherical intracavity inter-connection of expansion valve.
The aperture of described by-pass prot is more than throttle orifice aperture.
The present invention uses said structure, has the advantage that the by-pass prot by expansion valve, at high speed coolant by bypass
Kong Shi, utilizes contacting of spheroid and chamfering, when high speed coolant is by valve body, increases circulation area, makes more cold-producing medium lead to
Crossing valve body, the whistle sound etc. making coolant flow can eliminate automatically.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings；
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of by-pass prot of the present invention；
In Fig. 1～Fig. 2,1, expansion valve body；2, by-pass prot.
Detailed description of the invention
A kind of expansion valve assembly as shown in Fig. 1～Fig. 2, including expansion valve body 1, described expansion valve body 1 is provided with
Throttle orifice, the sidewall of described expansion valve body 1 is provided with by-pass prot 2.Described by-pass prot 2 and the ball in expansion valve body 1
Shape intracavity inter-connection.Described throttle orifice and the spherical intracavity inter-connection in expansion valve body 1.The aperture of described by-pass prot 1
More than throttle orifice aperture.
By the by-pass prot of expansion valve, when high speed coolant is by by-pass prot, utilize contacting, in high speed of spheroid and chamfering
When coolant is by valve body, increase circulation area, make more cold-producing medium can oneself by valve body, the whistle sound etc. making coolant flow
Dynamic elimination.
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.
