Household air conditioner throttle pipe

Abstract

A throttle pipe of a household air conditioner comprises a left moving block and a right moving block which are arranged in a metal tube; a left fixing block and a right fixing block are arranged between the left moving block and the right moving block; the fixing blocks are fixed on the inner wall of the metal tube; a left stopping block and a right stopping block are arranged outside the left moving block and the right moving block; the left stopping block and the right stopping block are fixed on the inner wall of the metal tube; the moving blocks are provided with moving block capillary pores which penetrate the axis of the moving blocks; the fixing blocks are provided with fixing block capillary pores which penetrate the axis of the fixing blocks and correspond to the positions of the moving block capillary pores; a plurality of axial overflow holes are also formed along the circumferential direction of the fixing blocks; the left moving block can glide between the left stopping block and the left fixing block; the right moving block can glide freely between the right stopping block and the right fixing block; the fixing blocks are made from multilayer metal plates or the whole metal plates; and the left and the right stopping blocks are made from copper, aluminum, steel or iron, and takes the shape of a full ring or is composed of a plurality of half-ring bodies. The throttle pipe has the advantages that the structure is more reasonable and the required matching length of the capillary tube is satisfied during the processes of cooling and heating, thereby reducing the consumption of refrigerant and energy and improving variety, quality and function of the product.

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...
