Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the utility model discloses a venturi formula knockout of taking air guide hole includes that the head of branch 1 and a plurality of divides liquid pipe 2, and the head of branch 1 front end is provided with feed liquor hole 11, and the rear end is provided with a plurality of and goes out liquid hole 13, respectively goes out liquid hole 13 annular equipartition in the rear end of dividing liquid head 1. A liquid separating cavity 12 is arranged in the liquid separating head, and a liquid inlet hole 11 is communicated with a liquid outlet hole 13 through the liquid separating cavity 12. Divide the quantity of liquid pipe 2 the same with going out liquid hole 13, divide 2 external diameters of liquid pipe slightly to be less than and go out liquid hole 13 aperture, divide the liquid pipe to insert out liquid hole 13 from dividing liquid head rear end to through welded fastening in going out liquid hole 13. When the liquid distributing device is used, according to the Venturi tube principle, air-conditioning refrigerants flow into the liquid distributing cavity 12 through the liquid inlet holes 11 and then uniformly flow into the liquid distributing pipes 2 through the liquid outlet holes 13, and therefore the air-conditioning refrigerants are distributed.
Each play liquid hole 13 axis can be on a parallel with branch liquid head axis (not shown in the figure), also can be certain contained angle with branch liquid head axis, as shown in fig. 2, preferably, this embodiment adopts the distribution form that is certain contained angle, and each play liquid hole 13 is conical distribution promptly, and the opening is towards branch liquid head 1 rear end.
Further, the liquid separation head 1 is provided with a plurality of air guide holes 3 on the side wall near one end of the liquid outlet hole 13, the number of the air guide holes 3 is the same as that of the liquid outlet holes 13, and the air guide holes are in one-to-one correspondence and communication with the liquid outlet holes 13, the central axes of the air guide holes 3 and the corresponding central axes of the liquid outlet holes 13 are on the same plane, the included angle α between the central axes of the air guide holes 3 and the corresponding central axes of the liquid outlet holes 13 at the liquid inlet end is less than or equal to 90 °, and preferably, the included angle α is 45-90 °.
Further, the aperture of the air-guide hole 3 is much smaller than that of the liquid outlet hole 13, and preferably, the aperture of the liquid outlet hole 13 is 3 to 6 times of that of the air-guide hole 3.
Further, go out liquid hole 13 end and be provided with stop device, preferably, stop device chooses for use the shoulder hole, as shown in fig. 2, the terminal degree of depth in each liquid hole is the same to accurate positioning divides liquid pipe 2 to insert the degree of depth of going out liquid hole 13, and guarantees that each divides liquid pipe 2 depth of insertion unanimous.
To further illustrate the size and position relationship of each part, taking the venturi tube type liquid separator with the gas guide hole as an example in this embodiment, the aperture of the liquid outlet hole 13 is 3mm, the outer diameter of the liquid separating tube 2 is slightly smaller than that of the liquid outlet hole 13, preferably, the difference between the aperture of the liquid outlet hole and the outer diameter of the liquid separating tube is 0.05-0.4 mm, the aperture of the gas guide hole 3 is preferably 0.5-1 mm, and preferably, the distance from the gas guide hole to the rear end face of the liquid separating head, that is, the outer end face of the liquid outlet hole is greater than 4mm.
When the liquid distributing pipe 2 is fixed by welding, firstly, one liquid distributing pipe 2 is inserted into the tail end of the corresponding liquid outlet hole 13, and then the outer end of the liquid outlet hole 13 is welded by adopting welding modes such as brazing and the like, so that the liquid distributing pipe 2 is fixed on the liquid distributing head 1 by welding, and the steps are repeated to complete the welding and fixing of all the liquid distributing pipes 2. During welding, the solder can flow to the position of the air guide hole 3 under high temperature and capillary action, redundant solder can flow out of the air guide hole 3, and meanwhile, the air guide hole 3 can be sealed by the solder after welding is finished due to the small aperture of the air guide hole 3.
