Abstract
The utility model provides a refrigerating fluid inlet structure of a flash tank for a centrifugal type unit. The refrigerating fluid inlet structure is mainly composed of a liquid inlet pipe and an end socket. The liquid inlet pipe enters the end socket and then is welded with a bend, the other end of the bend is upward and welded with a hush pipe, and the other end of the hush pipe is welded with a blocking plate. An energy-dissipating baffle is welded to the position, at a certain distance from the hush pipe, and close to the right side. According to the refrigerating fluid inlet structure, noise generated after high-speed liquid refrigerant enters the flash tank can be effectively lowered, the baffle on the right side of the hush pipe can eliminate the impact kinetic energy of the liquid refrigerant, impact fluctuation of the lower liquid level can be reduced, operation of the unit is made to be more stable, and the noise of the overall unit is lowered.
Description
Technical field
The utility model relates to a kind of central air-conditioning internal structure.
Background technology
Along with continuing of building of Chinese national economy, fast-developing, living standards of the people improve fast, the demand of the refrigeration air-conditioner of large standard ton is increasing, and centrifugal unit has been subject to numerous clients' favorable comment with its large cold, low noise, high energy efficiency and the characteristics such as reliable.
Flash tank is requisite parts in centrifugal unit, from the liquid refrigerant of condenser, through reducing pressure by regulating flow, enters flash tank, and flash distillation becomes saturated gas in flash tank, and the middle air entry that saturated gas enters compressor compresses; The liquid refrigerant that forms in flash tank is supplied the devaporation device.
But in centrifugal unit, when liquid refrigerant enters flash tank at a high speed, can produce high noisy and cold-producing medium impact liquid level and produce the problems such as fluctuation.
Summary of the invention
The purpose of this utility model is to provide a kind of refrigerant inlet structure of flash tank, to solve the problems of the technologies described above.
The utility model mainly is comprised of feed tube, end socket, and the technical scheme that solves its problem is after feed tube enters end socket, and with elbow welding, the elbow other end is directed upwardly, with the hush pipe welding, and hush pipe other end welding closure plate; , apart from hush pipe one segment distance, weld the energy dissipating baffle plate on the right side.
Elbow described in the utility model is 90 degree.
The circumferential perforate of hush pipe described in the utility model.
Adopt the utility model can effectively reduce the high speed liquid refrigerant and enter the noise that produces after flash tank, hush pipe right side baffle plate can be eliminated the impact kinetic energy of refrigerant liquid, reduce the impact fluctuation of its underpart liquid level, make unit operation more steady, the circumferential perforate of hush pipe can effectively reduce the unit noise, and the unit overall noise is lower.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described:
Fig. 1 is schematic diagram of the present utility model;
In figure, 1 is feed tube, and 2 is elbow, and 3 is end socket, and 4 is hush pipe, and 5 is closure plate, and 6 are the energy dissipating baffle plate, and 7 is housing.
The specific embodiment
As shown in the figure: after feed tube 1 entered end socket 3, with 90 degree elbow 2 welding, elbow 2 other ends were directed upwardly, with hush pipe 4 welding, and hush pipe 4 other end welding closure plates 5; , apart from hush pipe 4 one segment distances, weld energy dissipating baffle plate 6 on the right side; Hush pipe 4 surroundings are covered with hole.
During use, liquid cold-producing medium (containing a small amount of gas) is crossed hush pipe 4 by feed tube 1 and elbow 2 high velocity stream, carry out noise reduction, shunting by hush pipe 4, enter flash tank inside, after cold-producing medium outflow hush pipe 4 impinges upon end socket 3, housing 7 and energy dissipating baffle plate 6, change flow direction, reduce motion energy, fall under gravity to the flash tank bottom.
Claims (3)
1. the refrigerant inlet structure of a flash tank, mainly be comprised of feed tube, end socket, it is characterized in that, after feed tube entered end socket, with elbow welding, the elbow other end was directed upwardly, with the hush pipe welding, and hush pipe other end welding closure plate; , apart from hush pipe one segment distance, weld the energy dissipating baffle plate on the right side.
