Abstract: Provided in the present invention are a valve needle component and a flow regulating valve. The valve needle component includes: a screw, wherein the screw comprises a first rod section, a second rod section and a third rod section which are connected in sequence, the outer diameter of the first rod section is greater than the outer diameter of the second rod section, and the outer diameter of the second rod section is greater than the outer diameter of the third rod section; a bearing sleeved on the second rod section; and a bushing sleeved on the third rod section, wherein the bushing is welded to the third rod section, and two end surfaces of an inner ring of the bearing respectively abut against an end surface of the first rod section and an end surface of the bushing.

Abstract: A valve head structure and a flow regulating valve with the valve head structure. The valve head structure is disposed in a valve body of the flow regulating valve for closing or avoiding a valve port of the valve body. The valve head structure includes: a valve head, which is movably disposed in the valve body; and an accommodating groove, which is formed in the valve head and is used for accommodating fluid in the valve body, wherein a distance between the valve head and the valve port is adjustable, and when the valve head moves to a position where the distance with the valve port is the maximum, at least part of the accommodating groove is located in an accommodating cavity of the valve body.

Abstract: Disclosed is an electronic expansion valve. The electronic expansion valve includes a valve seat provided with a valve cavity and a valve port, wherein the valve port is arranged at an end portion of the valve cavity; a guide sleeve fixedly arranged on the valve seat, the guide sleeve is provided with a first guide hole, and the first guide hole is in communication with the valve cavity; and a valve needle movably arranged in the guide sleeve, wherein a first end of the valve needle penetrates out of the first guide hole to be arranged corresponding to the valve port, the valve needle is in clearance fit with the first guide hole, the valve needle is configured to control the valve port to be opened or closed, and a swingable amplitude of the valve needle in the first guide hole ranges from 0.4° to 2.4°.

Abstract: A valve needle assembly and an electronic expansion valve having same. The valve needle assembly includes: a valve sleeve, the valve sleeve having a cavity, and the valve sleeve having a first end and a second end arranged opposite each other; a bushing movably arranged in the cavity, the bushing being in limiting fit with the first end of the valve sleeve, and the bushing being used for driving the valve sleeve to move; a spring arranged in the cavity, wherein one end of the spring is connected with the bushing, and the other end of the spring is connected with the second end of the valve sleeve; and a sealing member fixedly arranged at the second end of the valve sleeve, the sealing member being configured for closing a valve port.

Abstract: An electronic expansion valve (1-100) is provided. The electronic expansion valve (1-100) includes: a screw (1-31), a valve needle (1-22), and an elastic member (1-25). One end of the elastic member (1-25) acts on the screw (1-31) and the other end acts on the valve needle (1-22). A bearing (1-23) is arranged between the screw (1-31) and the valve needle (1-22). The bearing (1-23) has an inner ring and an outer ring. One of the screw (1-31) and the valve needle (1-22) is fixed with the inner ring of the bearing (1-23), and the other acts on the outer ring of the bearing (1-23) through the elastic member (1-25). An air conditioning system using the electronic expansion valve (1-100) is provided. In the electronic expansion valve (1-100), the bearing (1-23) is arranged between the valve needle (1-22) and the screw (1-31).
