    • The present invention relates generally to valves for controlling the flow of fluid and, more particularly, to a valve which is controlled using a master key such that only an authorized person is able to turn the valve on and off. The valve controlled using a master key according to the present invention, which is constructed such that a fluid passage is controlled by rotating a handle relative to a body, includes a locking means for maintaining the locked state of the handle relative to the body. Furthermore, a master key slot, which extends to the locking means, is formed in the handle, so that, when a master key is inserted into the master key slot, the locked state of the handle is released such that the fluid passage can be controlled by rotation of the handle.
    • 本发明一般涉及用于控制流体流动的阀门,更具体地,涉及一种使用主钥匙来控制的阀门,使得仅授权人员能够打开和关闭阀门。 使用根据本发明的主键控制的阀门被构造成使得通过相对于主体旋转手柄来控制流体通道,包括用于保持手柄相对于身体的锁定状态的锁定装置。 此外,延伸到锁定装置的主键槽形成在手柄中,使得当主键插入主键槽时,手柄的锁定状态被释放,使得流体通道可以 由手柄旋转控制。
