Abstract
The utility model discloses a shunt used for an air conditioner which comprises a lower seat, an upper seat and an access pipe. The upper seat is in a pipy structure with the lower end processed to be a shrink mouth, the upper end of the access pipe is processed to be a second shrink mouth, the outside diameter of the second shrink mouth is matched with the inside diameter of the second shrink mouth, the upper end of the upper seat is connected with the lower seat, and the shrink mouth of the lower end is connected with the second shrink mouth of the access pipe. The utility model improves the upper seat to be in the pipy structure, greatly reduces the volume of the upper seat, causes the raw material amount of the upper seat to be reduced by two thirds, and lowers the raw material cost. Meanwhile, the volume of an inner cavity of the upper seat is increased to cause the interior space of a shunt cavity to be more than two times as large as before, and enough space is left for the arrangement of a shunt cone, thereby the shunt cone can be lengthened on the original base to enhance the shunt effect. The shrink mouth of the access pipe forms conical diameter variation transition, keeps a certain processing fillet, reduces system pressure loss and impact, and can efficiently lower the flow sound, thereby the purpose of lowering the noise is achieved.
Description
[technical field]
The utility model relates to the current divider that in the air-conditioning cold-producing medium is branched into some streams, is specifically related to the improvement to the cold-producing medium shunting effect.
[background technology]
Existing current divider is made of the current divider seat of honour, following of current divider and an access tube, and it has the following disadvantages:
1. current divider seat of honour volume is big, and internal cavities is little, and the raw material consumption is big, the cost height, and shunting inner space, chamber is little, and the shunting cone height is subjected to certain limitation, and shunting effect is even inadequately.
2. because there is the structure of unexpected reducing in the porch in shunting chamber, cause the pressure loss at this place to increase.And have liquid stream sound, machine noise in causing.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of idle call current divider, can effectively improve shunting effect, and can reduce the pressure loss and interior machine noise.
For achieving the above object, the utility model proposes a kind of idle call current divider, comprise following, the seat of honour, access tube, the described seat of honour is a tubular structure, reducing is processed in the lower end, and second reducing is processed in the upper end of described access tube, and the external diameter of described second reducing cooperates with the internal diameter of reducing, the upper end at the described seat of honour is connected with following, and the reducing of lower end is connected with second reducing of access tube.
As preferably, be provided with the branch flow cone of taper in the middle of described following the bottom, following seat forms the shunting chamber jointly with the internal cavities at the seat of honour.
The beneficial effects of the utility model: the utility model is improved to tubular structure with the seat of honour, has reduced the volume at the seat of honour greatly, makes the original minimizing 2/3rds of seat of honour raw material amount ratio, has reduced the cost of raw material.Simultaneously, seat of honour cavity volume increases, and it is many to make shunting inner space, chamber reach original twice, gives and divides flow cone to reserve enough spaces, divides flow cone to extend on the original basis, improves shunting effect.The reducing of access tube forms the transition of taper reducing, and keeps certain processing fillet, has reduced system pressure loss and impact, and can effectively reduce the liquid streaming voice, thereby reached the purpose that reduces noise.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the structural representation of prior art idle call current divider;
Fig. 2 is the structural representation of the utility model idle call current divider;
Fig. 3 is following a structural representation in the utility model idle call current divider;
Fig. 4 is the structural representation at the seat of honour in the utility model idle call current divider;
Fig. 5 is the structural representation of access tube in the utility model idle call current divider.
[specific embodiment]
Consult Fig. 1, the volume at the seat of honour is excessive in the prior art, and the inner space is too small.Because of adopting brass material processing, its structure can not be made substantial improvements.
Consult Fig. 2,3,4,5, the idle call current divider, comprise following 1, the seat of honour 2, access tube 3, the described seat of honour 2 is a tubular structure, reducing 21 is processed in the lower end, and second reducing 31 is processed in the upper end of described access tube 3, and the external diameter of described second reducing 31 cooperates with the internal diameter of reducing 21, the upper end at the described seat of honour 2 is connected with following 1, and the reducing 21 of lower end is connected with second reducing 31 of access tube 3.Be provided with the branch flow cone 11 of taper in the middle of described following 1 bottom, following seat 1 forms shunting chamber 12 jointly with the internal cavities at the seat of honour 2.Following seat 1 adopts brass material processing, and red copper materials processing is adopted at the seat of honour 2, and access tube 3 adopts the processing of copper pipe reducing.Adopt the seat of honour 2 of the tubulose of red copper materials processing can effectively increase the volume of shunting chamber 12, the increase of this volume is given and is divided flow cone 11 to reserve enough spaces, divide flow cone 11 to extend on the original basis, improve shunting effect, access tube 3 at one end carries out reducing processing, forms the transition of one section taper reducing, and keep certain processing fillet, this structure helps reducing the system pressure loss and impacts, and can effectively reduce the liquid streaming voice, thereby reaches the purpose that reduces noise.The seat of honour 2 can adopt copper tube reducing processing or copper plate stretch process to form.Following seat 1 adopts brass bar to process, and the branch flow cone 11 on it is suitably extending on original basis. and weld with access tube 3 after welding with following 1 at the seat of honour 2 again.
When refrigerant passes through access tube 3, at second reducing, 31 places of access tube 3 owing to there is reducing, refrigerant can enter shunting chamber 12 with higher flow velocity and pressure, under the effect of shunting chamber 12 that adequate space is arranged and branch flow cone 11, can make each arm position of current divider can obtain shunting as far as possible uniformly.Simultaneously owing to form the transition of one section taper reducing, and keep certain processing fillet, this structure helps reducing the system pressure loss and impacts, and can effectively reduce the liquid streaming voice, thereby reaches the purpose that reduces noise.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any structure after the utility model simple transformation is all belonged to protection domain of the present utility model.
