Abstract
The utility model discloses a fixed flow-limiting dispenser which includes a dispenser body comprising a liquid inlet and a liquid outlet; the liquid inlet is connected with the master liquid pipe in the air conditioner; the liquid outlet is provided with a plurality of dispensing holes, each of which is connected wit a corresponding evaporation pipe respectively; a core with a through hole in the center is embedded in the dispenser body, which can effectively control the refrigerant flow entering the dispenser and thus control the flow of the whole system. The utility model is simple in structure, uniform in flow-dispensing and can be widely applied to the domestic or commercial air-conditioning system.
Description
Technical field
The utility model relates to a kind of current limliting distributor, refers in particular to a kind of fixed current limliting distributor of idle call.
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.
The realization of the current limliting shunting function of tradition air-conditioning generally has dual mode: a kind of mode is that distributor is not provided with throttling arrangement, cold-producing medium enters each tap hole outflow that the port of export is directly passed through in the back from the entrance point of distributor, the refrigerant amount that is assigned to each tap hole like this is inhomogeneous, thereby the pressure imbalance that causes each group evaporation comb to bear influences result of use; Another kind of mode is to establish throttling devices such as capillary or expansion valve in addition at the distributor front end, and throttling arrangement and part flow arrangement are provided with separately, and this structural volume is big, cost is high, solder joint is many, exists and leaks hidden danger.
Summary of the invention
The utility model provide a kind of rational in infrastructure, shunting evenly, specified being used for air-conditioning system and having the fixed current limliting distributor of regulating system pressure drop function of flow.
A kind of fixed current limliting distributor, comprise distributor body, body comprises the liquid-inlet end and the port of export, the liquid-inlet end links to each other with main liquid tube in the air-conditioning, the liquid outlet end is provided with some tap holes, each tap hole links to each other with each group evaporation comb respectively, is embedded with core body in the described body, and the core body center has through hole.
Described liquid-inlet end port periphery gradually inwardly dwindles.
The utility model has been set up pore throttling device on the traditional dispensers basis, comparatively complicated originally throttling arrangement is condensed into a fixedly core body that has through hole, is embedded in the distributor body, thereby throttling arrangement and part flow arrangement are integrated in one.Distributor body and fixedly sealing between the core body, guarantee that cold-producing medium flows in the through hole at core body center via the liquid-inlet end, high accuracy control because of through hole, make the refrigerant flow that flows into distributor body certain, thereby cold-producing medium is assigned in each tap hole of liquid outlet end effectively, equably; The aperture of tap hole can be made the aperture of different-diameter according to different designs simultaneously, thereby makes the refrigerant flow that flows into evaporation (condensation) comb reach rated value, makes the exchange effect of evaporation (condensation) device reach best.
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 fixed current limliting distributor, comprise distributor body 1, body 1 comprises the liquid-inlet end 3 and the port of export 4, liquid-inlet end 3 links to each other with main liquid tube in the air-conditioning, and liquid outlet end 4 is provided with some tap holes 5, and each tap hole 5 links to each other with each group evaporation comb respectively, be embedded in the body 1 and be fixed with core body 2, core body 2 centers have through hole 6.
Adopted linear sealing and interference sealing means between core body 2 two ends and interlude and the distributor body 1 respectively, good airproof performance, liquid-inlet end 3 port peripheries gradually inwardly dwindle simultaneously, not only play sealing function, and core body 2 is played the restriction positioning action.
When cold-producing medium flows into from entrance point, because of distributor body 1 and fixedly adopted the many places sealing between the core body 2, force cold-producing medium via liquid-inlet end 3, can only in the through hole 6 of core body 2, flow into, thereby make the refrigerant flow that enters in the distributor body 1 reach rated value, thereby equably cold-producing medium is distributed to each tap hole 5, made the interior cold-producing medium of each diverter branch distribute equably and enter each evaporation (condensation) comb, thereby effectively play the current limliting shunting action.
Claims (2)
1. fixed current limliting distributor, comprise distributor body (1), body (1) comprises the liquid-inlet end (3) and the port of export (4), liquid-inlet end (3) links to each other with main liquid tube in the air-conditioning, liquid outlet end (4) is provided with some tap holes (5), each tap hole (5) links to each other with each group evaporation comb respectively, and it is characterized in that: be embedded with core body (2) in the described body (1), core body (2) center has through hole (6).
2. fixed current limliting distributor as claimed in claim 1 is characterized in that: described liquid-inlet end (3) port periphery gradually inwardly dwindles.
