Title:
BIDIRECTIONAL THERMOSTATIC EXPANSION VALVE AND SYSTEM INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2018/090916
Kind Code:
A1
Abstract:
Disclosed is a bidirectional thermostatic expansion valve, comprising a valve body (110), a valve core (130, 230), and a unidirectional flow assembly (150, 250). The valve body (110) comprises a valve seat (113), a first port (111) and a second port (112). The valve core (130, 230) is accommodated in the valve body (110) and has an abutting portion (133, 233) forming an orifice (120) with the valve seat (113), and the valve core (130, 230) can move relative to the valve body (110) between a first position and a second position. In the first position, the abutting portion (133, 233) abuts against the valve seat (113) so as to close the orifice (120); and in the second position, the abutting portion (133, 233) faces away from the valve seat (113) so as to open the orifice (120). The unidirectional flow assembly (150, 250) provides a flow path for communicating the first port (111) and the second port (112) and is constructed to allow a fluid to flow from the first port (111) to the second port (112) and prevent the fluid from flowing to the first port (111) from the second port (112).
