Air conditioning equipment, water cooling unit, stop structure and control method thereof

Abstract

The invention provides a stop structure. The stop structure comprises a valve body module, a stop module and a pressurization module, wherein the valve body module includes a valve body; the valve body is provided with an inlet, a hollow cavity and an outlet; the stop module is movably mounted in the hollow cavity for opening or closing the inlet; the pressurization module includes a pressure-adjustable pressure container; and one end of the stop module is movably arranged in the pressure container. The stop structure also has a pressurization function when having a stop function. A fluid enters the hollow cavity from the inlet of the valve body of the valve body module; at this time, the fluid pushes a baffle plate to enable a valve element to press the pressure container; the pressure in the pressure container is gradually increased; and the pressure of the fluid in the inlet is also gradually increased, so that the fluid can flow out from the outlet of the valve body, the adjustment of high and low pressure differences in a water cooling unit is convenient, and the stable operation of the water cooling unit is guaranteed; and meanwhile, a back pressure valve is canceled to optimize the overall structure of the water cooling unit. The invention further provides air conditioning equipment, the water cooling unit and a control method of the stop structure.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to an air-conditioning equipment, a water chiller, a non-return structure and a control method thereof. Background technique [0002] At present, check valves are more common in various large-scale chillers, and their function is to ensure that gas or liquid flows in a certain direction; when the flow direction of gas or liquid is reversed, the pressure generated by the gas or liquid pushes the spring to seal the outlet, preventing its reverse flow. However, the current check valve cannot adjust the high and low pressure difference in the chiller, and it needs to be used in conjunction with a back pressure valve, which increases the number of parts, resulting in a complex structure and inconvenient control and manipulation. Contents of the invention [0003] Based on this, it is necessary to solve the problem that the current check valve cannot independently ad...
