Document Type and Number:
WIPO Patent Application WO/2013/023562
Kind Code:
A1
Abstract:
A hydraulic valve for adjusting a password, comprising a valve mechanism (1), a displacement mechanism (2), and an identifier structure (3). The valve mechanism (1) comprises a valve body (101) and a valve core (102). The valve body (101) is provided thereon with oil passages (104 and 105). The displacement mechanism (2) comprises a displacement core sleeve (201) arranged on the valve mechanism (1), and the displacement core sleeve (201) is provided thereon with an oil passage (202). The identifier structure (3) is arranged on the valve mechanism (1) and/or on the displacement mechanism (2). The position of the displacement core sleeve (201) in the valve mechanism (1) is adjusted via the displacement mechanism (2). The position of the displacement core sleeve (201) is learned via the identifier structure (3). When simultaneously connected to the oil passages (104 and 105) on the valve body (101), the position in the valve mechanism of the oil passage (202) on the displacement core sleeve (201) is set as the password. A user needs only to adjust the position in the valve mechanism (1) of the oil passage (202) on the displacement core sleeve (201) to change the password, thus simplifying the operation of changing the password.
