Problems solved by technology
[0003] However, the two fixed blocks in the above-mentioned "Air Conditioning Refrigeration Throttle Tube" are provided with a plurality of small through-holes and capillary passages positioned at the axial center of the fixed block, so the processing of the two fixed blocks is comparatively difficult. Troublesome, high processing cost; and the axial length of the fixed block is long, it is difficult to process the overflow hole on the long fixed block, especially the capillary hole, and the throttling effect can only be changed by overall replacement It is realized by fixed block, the adaptability of this product is not strong, and the cost of replacement and processing is high

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] Such as Figure 1~3 Shown is a first embodiment of the invention.
[0027] 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 is in the shape of a round tube, the inner diameter of the valve body 1 is Φ5 ~ Φ30mm; the valve body 1 There are two left and right static spools 2 and 3 which are directly fixed with the valve body 1 in the inner interval, and there is also a static valve core 2 and 3 in the valve body 1 which can slide axially relative to the valve body 1 and is located at the left and right sides. The moving spool 4 between the static spools 2 and 3, the distance between the left and right static spools 2 and 3 is greater than the axial dimension of the moving spool 4, to ensure that the moving spool 4 can move ...

The invention relates to a throttle pipe for a household air conditioner, which comprises a tubular valve body, a left motionless valve core, a right motionless valve core and a motional valve core; the right motionless valve core is provided with a plurality of overflow holes penetrating in the axial direction for being passed by refrigerating agent and a right capillary bore, and a capillary bore is arranged in the motional valve core. The throttle pipe is characterized in that the left motionless valve core is provided with a left capillary bore; at least one of the left and the right motionless valve cores is formed through two motionless valve core monomers being spliced, and the two motionless valve core monomers are tightly adhered to form an integral motionless valve core. The two motionless valve core monomers are tightly adhered to form the integral motionless valve core, and the motionless valve core is formed through two motionless valve core monomers being spliced, therefore, the axial length of each monomer is relatively simple, the overflow holes or capillary bores are relatively easy to be processed on the monomers, and from experiments, the motionless valve core can change the throttling effect of the throttle pipe when being formed through the two spliced monomers, namely the throttling effect is different from that of the integral motionless valve core with the identical axial length.
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 capillary tubes. For example, a Chinese utility model patent "An Air Conditioning Refrigeration Throttle Tube" with a patent number of ZL200420090859.8 (announcement number of CN2769788Y) discloses such a Throttle tube, which includes a cylindrical moving block and a fixed block installed in the pipe, wherein the two ends of the moving block 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 Sliding 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 t...
