Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is
Embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of short-tube throttle valve disclosed in the utility model；
Fig. 2 is the sectional view of Fig. 1.
Detailed description of the invention
The utility model discloses a kind of short-tube throttle valve, mainly comprise the following steps: valve body, spool, the first mistake
Filter device and the second defecator.The shell that wherein outer wall of valve body preferably metal is made, it has been internally formed media flow
Passage.Spool is fixedly installed in the passage in valve body, and spool has the internal diameter throttling passage much smaller than passage, and by joint
Circulation road realizes the regulation to rate-of flow.Being provided with the first defecator in the channel, the first defecator is arranged on medium
The upstream of flowing, is mainly used in the impurity filtering in medium, reduces the possibility that in medium, vias inner walls is impacted by impurity, with
Time avoid impurity blocking spool in throttling passage, affect the service life of short-tube throttle valve.It is additionally provided with second in the channel
Defecator, the second defecator is arranged on the downstream of media flow, by the filtration of the second defecator so that medium
Flowing frequency change, thus reduce the probability of bubbles burst collision channel in medium so that noise source is weakened severely,
Thus reduce noise when short-tube throttle valve uses.In this utility model, it is not necessary to increase damping material parcel valve body, there is knot
Structure is rationally and the advantage of good reliability.
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of this utility model protection.
As depicted in figs. 1 and 2, short-tube throttle valve disclosed in the present embodiment is through type short-tube throttle valve, and it is main
It is applied in air-conditioning single cooler or similar equipment.As it can be seen, in the present embodiment, short-tube throttle valve includes valve body 1, spool
3, the first defecator 4 and the second defecator 5.The passage 2 of cold-producing medium flowing it is formed with in valve body 1.Passage 2 is provided with
Throttle valve core 3, spool 3 is fixedly installed in described passage 2, right to realize on the direction that the cold-producing medium shown in Fig. 1 flows
The regulation of cold-producing medium.
Specifically, in spool 3, it is formed with throttling passage, is not difficult to find out, in passage 2 in valve body 1 and spool 3
Between throttling passage, cross section of fluid channel reduces suddenly.This makes the flow velocity of cold-producing medium be greatly increased, cold-producing medium and throttling passage inwall
And between cold-producing medium, produce severe friction.In order to avoid the impurity in system blocks spool 3, so, cold-producing medium in passage 2
One end, upstream of flow direction is provided with the first defecator 4, for filtering the impurity in cold-producing medium.First defecator 4 is excellent
Elect cancellated filter as, the gauze filter that the gauze filter made such as metallic copper or other metal are made.For excellent
Changing filter effect, the first defecator 4 is preferably made cone, its center axis and passage 2 dead in line, and radius is along cold-producing medium
The direction of flowing is gradually increased until contacting with spool 3.First defecator 4 is fixedly installed in passage 2, it is to avoid high-pressure refrigeration
Agent collision causes the first defecator 4 to move in passage 2, affects filter effect.
Cold-producing medium flows in throttling passage, because rubbing action makes refrigerant pressure reduce, causes some refrigerant to boil
Rising evaporation, until throttling passage and the connectivity part of passage 2, cold-producing medium is gas-liquid two-phase state.The flow direction of corresponding cold-producing medium,
Flow out the one end in gas-liquid two-phase state at spool 3 and be fixedly installed the second defecator 5.The side of setting of the second defecator 5
Formula can be welding or other similar fixing connected mode, it is ensured that its position in passage 2 will not be along with cold-producing medium
Flow and be subjected to displacement, it is ensured that the stability in use of short-tube throttle valve.
Different from the defecator used in short-tube throttle valve of the prior art or associated pipe, the second defecator 5
Main Function be the cold-producing medium in gas-liquid two-phase state is carried out filter rectification, change cold-producing medium flowing frequency, reduce system
In cryogen, air pocket ruptures frequency, it is to avoid bubble impacts generation vibrations to tube wall, thus reaches to weaken noise source, reduces
The purpose of pipeline noise.The second preferred metallic netted structural of defecator 5, such as copper mesh, the sintered filter screen of rustless steel or other class
The drainage screen made like material.
The apolegamy of the second defecator 5 concrete shape is according to design conditions, the kind of cold-producing medium and the tool of spool 3
Shape is matched, and could be arranged to the filter screen equal with passage 2 cross section, multistorey strainer mesh, the filter screen of outside curved protrusion
Etc. various ways.One of which is preferred embodiment to be symmetrical arranged, specifically, by the second mistake with the first defecator 4
Filter device 5 is set to the gauze filter of cone, the central axis of the second defecator 5 and the central axes of valve body 1.
The internal diameter of the second defecator 5 is gradually reduced along cold-producing medium flow direction, so, on the one hand meets the flow path of cold-producing medium,
Can ensure that enough filter areas, on the other hand so that cold-producing medium is sufficiently filtered and rectification, prevent cold-producing medium
In bubble rupture the impact formed tube wall in the edge of drainage screen.
Compared with prior art, the short-tube throttle valve that the present embodiment is proposed is by the second mistake being fixedly installed in valve body
Filter device adjusts flow path and the flowing frequency of cold-producing medium in passage, it is to avoid in the bubble in the cold-producing medium of gas-liquid two-phase state
Rupture and tube wall is impacted, cause tube wall vibration to form noise.Thus during reducing short-tube throttle valve use on source
Noise, improve short-tube throttle valve practicality.In the present embodiment, it is not necessary to use damping material to realize sound insulation, it is a kind of solution
The certainly effective ways of short-tube throttle valve noise problem.
This utility model provides a kind of air-conditioner using above-mentioned short-tube throttle valve simultaneously.The concrete structure of short-tube throttle valve
Refer to the detailed description of above-described embodiment and the detailed description of Figure of description, do not repeat them here.This utility model institute is public
The air-conditioner opened can realize same technique effect.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；
Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that:
Technical scheme described in foregoing embodiments still can be modified by it, or carries out wherein portion of techniques feature
With replacing；And these amendments or replacement, do not make the essence of appropriate technical solution depart from this utility model each embodiment technology
The spirit and scope of scheme.
