Abstract

The invention discloses a stop-throttle valve consisting of a change valve and an external equalizer thermostatic expansion valve. The stop-throttle valve of the invention is applied to air-conditioning devices with different structures such as a multifunctional structure, a multi-split structure and the like so as to realize double functions of stop and throttle. The stop-throttle valve has the advantages of stable and reliable structure, low prices and wide industrial base and is an ideal substitute for the traditional stop-throttle valves, such as a solenoid valve connected in series with a capillary, a one-way valve connected in series with a capillary, a solenoid valve connected in series with a thermostatic expansion valve, an electronic expansion valve and the like.

Description

technical field [0001] The present invention relates to a throttle valve, more specifically, it relates to a cut-off throttle valve and its application. Background technique [0002] In the field of air-conditioning technology, a cut-off and throttle valve element with cut-off and throttling functions is often used, such as Chinese Patent Publication No. CN2771763Y, published on April 12, 2006, named as "multi-purpose refrigeration and heating air-conditioning device" and Chinese Patent Publication No. CN200955880Y, the publication date is October 3, 2007, and in the technical scheme disclosed in the name "Multipurpose Refrigeration and Heating Air Conditioning Device and Its Double Heat Recovery Device", the cut-off throttle valves used are: electromagnetic Valves are connected in series with capillary tubes, check valves are connected in series with capillary tubes, electronic expansion valves, bridge-type cut-off throttle valves, etc., to control the condensed liquid in t...
