Household air conditioner throttle pipe

Abstract

The invention discloses an air conditioning throttle pipe for domestic use, comprising a left movable block and a right movable block which are arranged in a metal pipe. A fixed block is arranged between the left movable block and the right movable block. A left stopping block is arranged outside the left movable block, and a right stopping block is arranged outside the right movable block. The left and the right stopping blocks are fixed on the internal wall of the metal pipe. The left and the right movable blocks are provided with movable block capillary small holes which penetrate through the axes thereof. The fixed block is provided with a fixed block capillary small hole which penetrates through the axes thereof and is corresponding to the positions of the movable block capillary small holes. The fixed block is also provided with a plurality of axial directional overflow holes. The left movable block can slide between the left stopping block and the fixed block. And the right movable block can slide freely between the right stopping block and the fixed block. The fixed block is made by multilayer metal sheets, forming into an integrative whole body. The left and right stopping blocks are made by copper or aluminum or steel or iron, and are ring-shaped or comprise a plurality of semi-rings. The air conditioning throttle pipe has the advantages that the air conditioning throttle pipe has more reasonable structure, is favorable to meet the length requirement of the capillary tube needed when refrigerating and heating, can debase the consumption of refrigerant and energy, and can improve the quality and functions of products.

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 which can reduce refrigerant and energy consumption and improve product functions. Background technique [0002] There are many structural forms of the existing household air conditioner flow regulating tubes, among which the Chinese Patent No. 200420090859.8 is a "throttle tube for air conditioning and refrigeration", which 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...

AI Technical Summary

Problems solved by technology

[0003] However, the moving block of the above-mentioned "Air Conditioning Refrigeration Throttle Tube" is an integral structure, which is not conducive to satisfying the matching of various capillary lengths required for cooling and heating; thus affecting the expansion of product varieties and the improvement of product functions
