Problems solved by technology

[0002] In refrigeration systems, such as vehicle air conditioners, household air conditioners, and even refrigerated systems, throttling elements, such as expansion valves, thermal expansion valves or electronic expansion valves, are required. The throttling elements play a role in throttling and expansion in the system. effect, but some systems may be used in two or more parts that need to be cooled

Embodiment Construction

[0021] The throttling device according to the specific embodiment of the present invention includes a valve body assembly, a valve core assembly, and a nut assembly. The nut assembly is relatively fixed to the valve body assembly; the valve body assembly has at least two interfaces: the first interface and the second interface, and the throttling device also has a third interface, and the third interface can be arranged on the valve body assembly Or other components, the valve body assembly also includes a valve port portion, the valve port portion has a valve port matched with the valve core, and the valve core is set in cooperation with the valve port. The threaded screw fits the nut, and the nut is relatively fixed, so that when the screw is driven to rotate, the rotation changes into an up and down movement within a certain range, so that the valve core can be driven to move up and down within a certain stroke, that is, the valve core can move relative to the The valve por...

Abstract

The invention discloses a throttling device. The throttling device comprises a valve body assembly (10), a valve core assembly (20), a nut assembly (41), a lead screw, a valve port part and a throttling part, wherein the lead screw is in screw-thread fit with a nut; the nut assembly (41) is fixedly arranged relative to the valve body assembly (10); the valve body assembly is provided with three interfaces: the first interface (121), the second interface (122) and the third interface (123); a valve port is formed in the valve port part; a throttling hole is formed in the throttling part; and the third interface communicates with the first interface through the throttling hole. According to the throttling device, the valve port and the throttling hole are separately formed in the throttlingdevice, and the opening degree of the valve port is adjusted through the action of a valve core, so that the opening degree of the valve port is controlled, the fluid passing through the valve port and the fluid passing through the throttling hole are adjusted and distributed, and the distribution and throttling of two flow paths are achieved through minor modification.

Description

【Technical field】 [0001] The present invention relates to the technical field of refrigeration, or to the technical field of fluid control. 【Background technique】 [0002] In refrigeration systems, such as vehicle air conditioners, household air conditioners, and even refrigerated systems, throttling elements, such as expansion valves, thermal expansion valves or electronic expansion valves, are required. The throttling elements play a role in throttling and expansion in the system. function, but some systems may be used in two or more parts that need to be cooled. For example, some air conditioners may be used for two different occasions, such as two rooms that need to be cooled or heated separately. For example, vehicle air conditioners are sometimes controlled separately for the cockpit and passenger compartment, and some new energy vehicles may have separate controls for the cabin and battery. Simultaneous control, in order to meet these requirements, multiple throttlin...
