Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as Figure 1~6 Shown is a first embodiment of the invention.

[0026] A household air conditioner regulating pipe, including a tubular valve body 1, the valve body 1 is generally made of copper or aluminum or steel pipe, the valve body 1 is in the shape of a round tube, the inner diameter of the valve body 1 is Φ5 ~ Φ30mm; the valve body 1 is made of From left to right, the first stopper 5, the static valve core 2 and the second stopper 6, which are directly fixed to the valve body 1, are provided at intervals. There are also two valves in the valve body 1 that can slide axially relative to the valve body 1. And located in the first moving spool 3 and the second moving spool 4, the first moving spool 3 is located between the first stopper 5 and the static spool 2, the second moving spool 4 is located between the second stopper 6 a...

Abstract

The invention relates to a throttle pipe of a household air conditioner. The throttle pipe comprises a tubular valve body, and a stationary valve core and dynamic valve cores are arranged in the valve body. The throttle pipe is characterized by only one stationary valve core which only has a capillary core channel penetrating an axle center thereof; and two dynamic valve cores, namely a first dynamic valve core and a second dynamic valve core respectively, wherein, the first dynamic valve core is provided with a first capillary core penetrating an axle thereof, and peripheral surface of the first dynamic valve core is opened with at least one groove throughout the peripheral surface, and the second dynamic valve core is only provided with one second capillary core penetrating the axle center thereof; and the throttle pipe further comprises a first block component and a second block component with channels, the first dynamic valve core is positioned between the first block component and the stationary valve core, and the second dynamic valve core is positioned between the second block component and the stationary valve core. The dynamic valve core directly slides in the valve body, and the structure of the stationary valve core is simpler in relation to structure of a valve seat in a throttle valve, and the stationary valve core is also provided with the capillary core channels, which ensure better throttling effect.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a household air conditioner flow regulating pipe. Background technique [0002] The throttling structure in existing household air conditioners and other small-scale refrigeration equipment generally adopts capillaries, such as a Chinese utility model patent "two-way throttling device" whose patent number is ZL99245856.0 (notification number is CN2386402A) discloses a two-way throttle It mainly has a tubular device. There are two oppositely arranged valve seats in the device. Each valve seat is equipped with a movable valve core with an axial fine hole in the middle. The axial direction of the two valve cores is The pores are one large and one small, which are respectively used for cooling and heating processes. In addition, a fluid filter is respectively arranged in the tubular body at the outer end of the two valve cores. [0003] For example, a Chinese ut...
