Abstract
The utility model is a detachable current limiting distributor which is formed sequentially by a matching body, a valve body, a flange and a connecting pipe, wherein the matching body is equipped with a plurality of relief holes, each relief hole is correspondingly communicated with each group if evaporating rake manifold inside the air conditioner, a valve separated from the distributor is equipped inside the distributor, the valve comprises a valve seat and a valve core equipped inside the valve seat and matched with the valve seat, the center of the valve core is equipped with a via hole, one end of the valve seat is equipped inside the distributor, the other end is sleeved inside the flange and the flange is communicated with the connecting pipe. The utility model separates the valve body and the distributor body to equip them respectively, so a whole change of the valve seat and the valve core can be performed when being changed, thereby keeping the valve seat and the valve core always in the best matching, compared with the prior separator, which has the advantages of a more reasonable structure, a better sealing feature, a more reliable feature and a long using life.
Description
Technical field
The utility model relates to a kind of current limliting distributor, refers in particular to a kind of removable current limliting distributor that is used for heat pump type air conditioner.
Background technology
The current limliting part flow arrangement generally is located at preceding current limliting and the shunting action of being used for of evaporimeter (condenser) in the air-conditioning system, and its entrance point connects the main body pipeline, and the port of export is provided with some tap holes, each tap hole and the corresponding connection of each group evaporation comb.
Be provided with valve body in the branch part of traditional removable current limliting dispenser assembly, promptly valve body directly is machined in the distributor, can't change with spool, can only change spool separately.And general valve seat cooperates when making one to one with spool, thereby makes valve seat and spool can't reach best fit.
The sealing of valve seat and spool generally has two kinds of forms, and a kind of is to adopt teflon seal, because of polytetrafluoroethylene (PTFE) is nonmetal, so this kind sealing to environmental requirement than higher, be not suitable for the condition of high temperature, the life-span is also shorter.Another kind is to adopt the all-metal sealing, and this kind sealing is very high to the requirement of sealing surface, because of spool is a detachable, often because of having enough to meet the need or changing worker's specialty inadequately, damages sealing surface, influences systematic function.And in welding process, can influence the perfection that valve seat cooperates with spool because of heating.
Summary of the invention
The utility model provides a kind of removable current limliting distributor, and valve body is separated setting separately with dividing part, can change valve seat and spool integral body when changing, thereby can make valve seat and spool remain best fit.
A kind of removable current limliting distributor, form by a minute part, valve body, flange and tube connector successively, divide part to have some tap holes, each tap hole and the corresponding connection of interior each the group evaporation comb of air-conditioning are provided with the valve body that is independent of the branch part in the described minute part, and valve body comprises valve seat and is located at the interior spool that cooperates with valve seat of valve seat, center spool has through hole, one end of valve seat places in the branch part, and the other end is socketed in the flange, and flange is communicated with tube connector.
Described valve seat is provided with back-up ring near tube connector one end.
Described valve seat sidewall is provided with some incremental holes.
The filter screen that is equipped with in the described tube connector.
The junction of described minute part, valve seat and flange is provided with sealing ring.
Be arranged with on the junction outer wall of described minute part and flange and receive son.
The utility model separates setting separately with valve body with dividing part, can change valve seat and spool integral body when changing, thereby can make valve seat and spool remain best fit; Adopt the all-metal sealing between valve seat and the spool, good airproof performance; Divide and adopt the sealing ring sealing between part, valve seat, the flange, make it form an independently inner-cavity structure; Set up some incremental holes on the valve seat, cold-producing medium is flow through from the incremental conductive channel that forms between incremental hole and valve seat and flange, increased through-current capacity, reduced noise.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of removable current limliting distributor, successively by minute part 1, be located at the valve body, flange 7 and the tube connector 8 that are independent of branch part 1 in the branch part 1 and form, divide part 1 to have some tap holes 12, each tap hole 12 and the corresponding connection of each group evaporation comb, tube connector 8 connects evaporimeter (condenser) or other air supply rate.
Valve body comprises valve seat 2, be located at the spools 3 that cooperate with valve seat 2 in the valve seat 2 and be located at the back-up ring 6 of valve seat 2 close tube connector 8 one ends, and valve seat 2 centers are provided with passage, and sidewall is provided with some incremental holes 4.Spool 3 centers have through hole 5, and an end of valve seat 2 places in the branch part 1, and the other end is socketed in the flange 7, and flange 7 is communicated with tube connectors 8, divide the junction outer wall of part 1 and flange 7 to be arranged with to receive son 10, are used for fastening minute part 1 and flange 7.Filter screen 9 is housed in the tube connector 8, can carries out filter cleaning to the cold-producing medium by tube connector 8, filter screen 9 adopts the interference fit form, and replaceable.
Divide the junction of part 1, valve seat 2 and flange 7 to be provided with sealing ring 11, be used to improve the sealing property of distributor.
When cold-producing medium when right-hand member enters, filtration by filter screen 9, clean cold-producing medium is entered in the distributor, because a pressure left side is low right high, spool 3 is pushed to left end and cooperates subsides mutually with the tunnel ends of valve seat 2, adopted the all-metal sealing between spool 3 and the valve seat 2, flange 7, valve seat 2,1 of branch part adopt sealing ring 11 sealings, thereby force cold-producing medium in the through hole 5 of spool 3, to pass through, because the through hole 5 of spool 3 is by accurate design, thereby make cold-producing medium reach specified flow, thereby realize specified function by whole distributor.When cold-producing medium when left end enters, because the effect of pressure, and make spool 3 shift to right-hand member back-up ring 6 places, because design has several incremental holes 4 on the valve seat 2, make cold-producing medium from valve seat 2 sidewalls incremental hole 4 and the incremental passage of valve seat 2 and 7 formation of flange flow out, thereby effectively increased the conducting flow, reduced noise.
