THERMAL EXPANSION VALVE WITH ONE-WAY CONTROL FUNCTION

摘要

A thermal expansion valve with one-way control function includes a valve body (1) having an inlet passage (11) and an out passage (12), a temperature sensor (2) installed on one end of said valve body (1), and a first valve core component (4) installed in an inside chamber (13) of said valve body (1). Said first valve core component (4) includes a first valve core (42) and a valve rod (41) against said temperature sensor (2).Said valve body (1) also includes an accommodation component (16) extending from said inlet passage (11) into said valve body (1) and coaxially installed with said inlet passage (11). Said accommodation component (16) has a second valve port (15) connected with said inside chamber (13). Said accommodation component (16) has a second valve core component (5) having a supporting piece (51) and a second valve core (52) matching said second valve port (15). The processing of the structure is convenient and the assembly of the second valve core component is simple and reliable.
