Household air conditioner throttle pipe

Abstract

The invention relates to a household air-conditioning regulating pipe, which includes a valve body, a static valve core, and a moving valve core. The static valve core has only one capillary passage through its axis. The spool is the first moving spool and the second moving spool located on both sides of the static spool. The first moving spool has a capillary hole running through its axis and at least two axially penetrating overflow holes. The movable spool has at least one capillary hole that runs through its axis, and the throttle tube also includes a first stopper and a second stopper, the two stoppers are respectively arranged at two ends of the valve body, and the first movable spool Located between the first blocking piece and the static valve core, the second moving valve core is located between the second blocking piece and the static valve core. Two moving spools are used, and the throttling tube has two dynamic throttling processes during the working process, and the throttling effect is good; after the axial direction passes through the overflow hole and the capillary hole, it directly flows through the refrigerant channel of the blocking member. Simplifies the flow path of the movable spool.

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 refrigeration equipment generally adopts a throttle valve or a throttle block structure, such as a Chinese utility model patent "throttle valve" with a patent number of ZL97236534.6 (announcement number CN2295085Y). A throttle valve, characterized in that: two opposite valves A and B are fixed in the casing, a: valve A includes a valve body with a gasket fixed at the end, and a through hole is opened in the middle of the valve body, the size of which is There is a valve core in the aperture part, and there is a spray hole in the middle of the valve core, and a filter screen is connected to the end of the valve body opposite to the inlet and outlet; b: Valve B includes a valve body with a gasket fixed o...

Problems solved by technology

The fluid passage on the outer ring of the auxiliary orifice plate (equivalent to the moving block or moving valve core) in the throttling device is the main fluid passage. In order to make the fluid passing through the main fluid passage flow through the fluid through hole on the baffle, it needs A piece is dug out at the back of the placement part to form an upward flow path for the fluid passing through the fluid channel, so the structure of the auxiliary orifice plate is relatively complicated; there is only one auxiliary orifice plate (equivalent to the moving block or moving valve core), Only one throttling can be performed, which is not conducive to satisfying the throttling intensity required to match the cooling and heating of household air conditioners, so the throttling effect of various existing throttling tubes can be further improved
