Abstract
A kind of duct type filtering throttling part flow arrangement of the utility model is related to Refrigeration ＆ Air-Conditioning throttling technology field, and in particular to a kind of device of duct type filtering throttling shunting unification.0.8mm or so capillary can only be accomplished, copper tube very long in refrigeration pipe and in tortuous shape, easily welded in welding stifled.Material cost and processing charges are higher, and need to account for larger installing space.This practicality is a kind of duct type filtering throttling part flow arrangement, is provided with screen pack and valve element in body, body is divided into import and export end and restriction three parts, and fixation, valve element and body coaxial inner conductor are withheld by muscle of withholding vertical on body；Screen pack one end is resisted against on the end face of valve element, is fixed by multiple convex points uniform on body, and refrigerant enters from entrance point, is throttled by strainer filtering, then through the valve element in restriction, is shunted from the port of export.Below 0.5mm can be machined to using this practical valve element diameter of bore, greatlys save Master Cost and processing charges.Save installing space.
Description
Technical field
It the utility model is related to Refrigeration ＆ Air-Conditioning throttling technology field, and in particular to a kind of duct type filtering throttling shunting
The device of unification.
Background technology
Capillary is the element for realizing reducing pressure by regulating flow in refrigeration pipe, red copper usually very elongated and in tortuous shape
Pipe.In most refrigeration systems simultaneously, it is often necessary to realize the work(of throttling and shunting using capillaries more than 2 tunnels or 2 tunnels
Energy.Due under current technological level, on the one hand, the internal diameter for drawing capillary is difficult to be made very small, and general minimum can only be done
Arrive 0.8mm or so；On the other hand, can be made very small even if drawing the internal diameter of capillary, as too small capillary is welding
Easily weld stifled when connecing and dare not use.Therefore, in order to realize larger reducing pressure by regulating flow amount, it is necessary to smaller using endoporus but be not
Sufficiently small and capillary that length is very long, it is higher that this results in the material cost of capillary and processing charges, and need to occupy
Larger installing space.
Utility model content
Deficiency of this practical purpose aiming at prior art, there is provided a kind of cost is low and can substitute the throttling of capillary
With the device of shunting.
A kind of duct type filtering throttling part flow arrangement, including body, body is interior to be provided with screen pack and valve element, described body
It is divided into the port of export, restriction and entrance point three parts, it is described that fixation, described valve are withheld by muscle of withholding vertical on body
Core and body coaxial inner conductor；Screen pack one end is resisted against on the end face of valve element, is fixed by multiple convex points uniform on body,
Refrigerant from entrance point enter, throttled by strainer filtering, then through the valve element in restriction, shunted from the port of export and
Go out.
As further improving and supplementing to such scheme, this practicality also includes following additional technical feature：
The valve element outer circumference surface is provided with the annular groove of multiple equidistantly distributeds so that it is more reliable to withhold fixation.
The material of the valve element is brass or aluminium.
The diameter of bore of the valve element is much smaller than the diameter of bore of conventional capillaries.
The material of the body is one kind of red copper, aluminium or stainless steel.
Described screen pack is made up of two parts, and stainless steel wire network interface end riveting is in brass network folder.
The body is provided with salient point in the positioning of capillary, therefore without setting positioner again on capillary.
It can reach following beneficial effect using the utility model：
1st, because the diameter of bore of valve element can be machined to below 0.5mm, significantly less than the diameter of bore of capillary, therefore make
It is the capillary that alternative decades of times is grown with very short valve element, and plays equal reducing pressure by regulating flow effect, therefore greatlys save material
Material expense and processing charges.
2nd, installing space is substantially saved.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is left view of the present utility model.
Fig. 4 is upward view of the present utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As Figure 1-4, the utility model is a kind of duct type filtering throttling part flow arrangement.
Duct type filtering throttling part flow arrangement described in the present embodiment, including body 1, body 1 is interior to be provided with screen pack 2 and Huang
The valve element 3 of copper, described screen pack 2 are made up of two parts, and 21 mouthfuls of end rivetings of stainless steel cloth are in brass network folder 22, refrigerant stream
Through first being filtered before valve element 3, to prevent from blocking throttling valve core.Described body 1 divides for the port of export 11, restriction 12 and entrance point 15
Three parts, described valve element 3 are fixed by muscle 13 of withholding vertical on body 1, described valve element 3 and the coaxial inner conductor of body 1, valve
The diameter of endoporus 32 of core 3 can be machined to below 0.5mm, therefore the capillary that can substitute decades of times length is throttled.
The one end of screen pack 2 is resisted against on the end face of valve element 3, and is positioned simultaneously by multiple interior salient points 14 uniform on body 1
Fixed, refrigerant enters from entrance point 15, filtered by filter screen 2, then is throttled through the endoporus 32 on valve element 3, then flow direction outlet
End 11, the shunting being divided into two.
This throttling arrangement is process through following steps, and body 1 after drawing pipe blanking by, through striking out entrance point 15, beating
Positioning convex point 14, screen pack 2 and throttling valve core 3 are installed, valve element 3 is withheld and fixes, then the port of export 11 is stamping.
Further, the outer circumference surface of the valve element 3 is provided with the annular groove 31 of multiple equidistantly distributeds so that withholds solid
It is fixed more reliable.
Further, the material of the body 1 is one kind of red copper, aluminium or stainless steel, can use aluminium or stainless steel, material into
This is low.
Further, the body 1 is provided with salient point 16 in the positioning of capillary, directly carries out welding without other fixed
Position.
It is above preferred embodiment of the present utility model, the scope of protection of the utility model is not limited, for ability
The deformation and improvement that field technique personnel make according to mentality of designing of the present utility model, should all be considered as protection of the present utility model
Within the scope of.
