Problems solved by technology

[0004] However, due to the large volume of large-scale refrigeration units, the cleanliness of the system cannot be completely free of slag. If these slag enter the orifice with the flow of refrigerant, it is likely to cause blockage of the orifice, resulting in the failure of the throttling effect, making the The refrigeration and cooling process cannot be carried out normally
[0005] At present, there is also a filter screen in front of the pipeline to prevent the entry of slag, but it undoubtedly increases the material. At the same time, because the filter screen is added to the pipeline system, welding leaks are added in the middle

Abstract

The invention discloses a throttling device, which simultaneously has the cooling throttling effect and the function of self-blocking prevention. The throttling device includes a front-end throttling section and a rear-end pipeline connection section; wherein, the front-end throttling section plays a major throttling and anti-blocking role, and it includes a throttling orifice, an inclined wall surface outside the orifice, and an inclined wall The threaded groove on the wall; the rear end pipeline connection section, which includes two steps, is mainly used for pipeline connection. This scheme uses the spiral flow of fluid inside the pipeline to wash away the clogged slag, which has the function of preventing clogging itself, and has a simple structure, safety and reliability. The invention also discloses a refrigerating unit using the throttling device.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration unit and a throttling device thereof. Background technique [0002] In the refrigeration unit, the throttling device is an indispensable mechanism. Currently commonly used throttling devices include capillary tubes, throttling orifice plates, electronic expansion valves, thermal expansion valves, etc. Among them, throttling orifice plates are widely used because they have no mechanical moving parts and are simple in structure. [0003] However, in the process of use, if the orifice is very small in a device with a small flow rate, especially in a large-scale refrigeration unit, the cooling capacity of the motor cooling, lubricating oil cooling and other devices is very small, so the flow that needs to be throttled is also large. Very small, the natural orifice is also very small, its structure can refer to figure 1 shown. [0004] However, due t...
