Description

Technical Field

[0001] The invention relates to the field of throttle valve processing, in particular to an inner cavity grinding device for processing a central air-conditioning throttle valve. Background Art

[0002] The air conditioning throttle valve, also known as the electronic expansion valve, is an important component in the air conditioning system. It is usually controlled by a microprocessor and is used to adjust the flow of air conditioning refrigerant to achieve indoor temperature control. This valve is generally installed near the compressor of the variable frequency air conditioner, replacing the traditional capillary tube, throttling the refrigerant through the small hole in the valve, and working together with the compressor to form high and low pressure areas to ensure the normal operation of the refrigeration cycle. The working principle of the air conditioning throttle valve is to adjust the pressure according to the difference between the indoor temperature and the set temperature, thereby changing the flow rate of the refrigerant. When the indoor temperature is higher than the set temperature, the throttle valve will increase the pressure and speed up the refrigerant flow rate; otherwise, it will reduce the pressure and slow down the refrigerant flow rate. In this way, the air conditioning throttle valve can accurately control the indoor temperature to reach the set comfortable temperature, avoid excessive cooling or heating, and achieve energy saving. In addition, the air conditioning throttle valve can also control the flow rate of the refrigerant to avoid system overload and excessive pressure, thereby protecting the air conditioning system.

[0003] The air conditioning throttle valve is used for the circulation of refrigerant. The surface of the inner wall of the existing regulating valve is usually manually polished to remove burrs. Manual polishing is time-consuming and labor-intensive, and it is easy to over-polish, resulting in reduced use intensity of the throttle valve and low efficiency. In addition, some fine burrs are not polished thoroughly, resulting in poor circulation effect of the refrigerant liquid due to the resistance of the burrs during circulation, and the refrigeration effect is deteriorated; Therefore, an inner cavity grinding device for processing a central air-conditioning throttle valve is proposed to solve the above problems.

Manual polishing is time-consuming and labor-intensive, and is prone to over-polishing, resulting in reduced intensity and low efficiency of the throttle valve. In addition, some fine burrs are not polished thoroughly, resulting in poor circulation effect of the refrigerant due to the resistance of the burrs during circulation, thereby deteriorating the refrigeration effect.
