Abstract

The invention discloses a throttling globe valve and an air conditioner system with the same. The throttling globe valve includes a valve body with a valve cavity and a valve stem arranged in the valve cavity. The valve body is also provided with a vertical joint and a horizontal joint communicating with the valve cavity. The vertical joint communicates with the valve cavity through a valve port part. The valve port part includes a throttling hole section. The throttling globe valve also includes a valve core with the throttling hole section. The valve core is located between the valve port part and the valve stem, and can move down along the valve cavity so as to bear against the valve port part, or move up along the valve cavity so as to detach from the valve port part. An elastic component bears against a position between the valve core and the valve port part. The throttling globe valve also includes a limit structure for limiting the position of the elastic component. The structure design of the throttling globe valve can support and position the valve core so as to reduce the probability of the deviation of the valve core and avoid the vibration during the up-down movement ofthe valve core, and the noise is small.

Description

technical field [0001] The invention relates to the technical field of refrigeration systems, in particular to a throttling stop valve and an air-conditioning system having the same. Background technique [0002] In the air conditioning system, the shut-off valve is mainly used to connect the indoor unit and the outdoor unit, and it only has a shut-off function. [0003] The air-conditioning system also needs throttling components to realize the throttling function. At present, the throttling filter devices commonly used in the air-conditioning system are main capillary, auxiliary capillary, filter and one-way valve. [0004] The globe valve and throttling filter device are relatively independent components in the pipeline of the air conditioning system. They are mainly connected to the pipeline by welding. Due to the large number of parts and correspondingly, there are many solder joints, which are prone to leakage and occupy a large space . [0005] In order to solve the...
