PURPOSE: A valve for preventing releasing and malfunction of a handle is provided to prevent the arbitrary change of fluid flow rate at places where vibration frequently generates. CONSTITUTION: A valve for preventing releasing and malfunction of a handle comprises a body member(10), a first fluid flowing port(20), a second fluid flowing port(30), an opening and closing member(40), a handle member(50), a stop plate(60), a wire spring member(70), and a master key(80). The main member has a fluid flowing passage(12). The first fluid flowing port is coupled to one end of the body member and is communicated with the fluid flowing passage. The second fluid flowing port is coupled to the other end of the body member and is communicated with the fluid flowing passage. The opening and closing member is located in the fluid flowing passage of the body member and is rotated in the fluid flowing passage to allow or block the flow of the fluid in the fluid flowing passage. The handle member rotates the opening and closing member. The stop plate has a positioning hole. The wire spring member is located in the handle member and has a curved part(73). The master key is inserted in a handle insertion groove and rotates the handle member. |
