Household air conditioner throttle pipe

Abstract

The invention discloses an air conditioning throttle pipe for domestic use, comprising a movable block arranged in a metal pipe. The left and the right sides of the movable block are respectively provided with a first left fixed block, a second left fixed block, a first right fixed block and a second right fixed block. The movable block and the fixed blocks are respectively provided with capillarysmall holes which penetrate through the axes thereof. The movable block can slide freely between the second left fixed block and the first right fixed block. The fixed blocks are provided with a plurality of axial directional overflow holes along the circumference direction thereof. The end faces of the second left fixed block and the first right fixed block which are contacted with the movable block are shaped in concave cone or plane or concave spherical surface, and the other end faces are shaped in plane. The both end faces of the first left fixed block and the second right fixed block are shaped in plane. A certain distance is arranged respectively between the first left fixed block and the second left fixed block, and between the second right fixed block and the first right fixed block. The movable block and the fixed blocks are made by multilayer metal sheets, forming into an integrative whole body. The invention has the advantages that the air conditioning throttle pipe is favorable to meet the length requirement of the capillary tube needed when refrigerating and heating, is favorable to the production and adjustment in batch production process, improves product quality,and reduces production cost.

Description

technical field [0001] The invention relates to the technical field of household air conditioners, in particular to a household air conditioner flow regulating tube with the best energy-efficiency ratio that can significantly reduce refrigerant and energy consumption. Background technique [0002] Existing home air conditioner flow regulating tubes have many structural forms, among which Chinese patent No. 200420090859.8 "A Throttle Tube for Air Conditioning Refrigeration" includes a cylindrical moving block and a fixed block installed in the pipeline, wherein the moving block Both ends are convex conical surfaces, and a small hole runs through the axis of the moving block, which is a refrigerant channel. The moving block can slide freely in the cavity formed by the fixed block and the pipe wall; the fixed block consists of two pieces , separated by an appropriate distance and respectively fixed on the inner wall of the pipeline, the end surface adjacent to the moving block ...

AI Technical Summary

Problems solved by technology

[0003] However, the fixed block of the above-mentioned "A Kind of Air Conditioning Refrigeration Throttle Tube" is an integral structure with fixed axial dimensions on the left and right sides, and the length of the capillary channel through which the refrigerant flows from the two directions is the same, which is not conducive to satisfying the requirements of refrigeration and refrigeration respectively. Matching capillary length for heating

Moreover, it is inconvenient to make and adjust in mass production
