Description

Valve with self-locking and two-way interlocking functions Technical Field The application relates to the field of valves, in particular to a valve with self-locking and bidirectional interlocking functions. Background A cold fluid distribution unit (CDU) is a cooling circuit used to condition cold fluid in a TCS or DECS system and circulate the cold fluid through the circuit to a rack, cabinet, or data communication equipment. At present, the pipeline in the liquid cooling circulation system is usually connected through a connecting valve, so that the liquid cooling medium circulates in the pipeline. In the traditional mode, a valve core is usually arranged in a valve body of the valve, a handle for driving the valve core to act is arranged on the valve body, the valve core is driven to move or rotate through the handle, the valve is opened and closed, and the valves on different pipelines are connected to realize the communication of the different pipelines. However, when the pipelines in the cooling system are connected through the valve, good tightness is usually required to be ensured, and the handle on the valve in the traditional mode is easy to operate by mistake in the connection process, so that the valve is opened by mistake, the problems of medium leakage and the like occur, and the working condition of the whole cooling system is influenced. Disclosure of Invention In order to solve the problem that a valve is easy to open by mistake during pipeline connection, the application provides a valve with self-locking and bidirectional interlocking functions. The application provides a valve with self-locking and two-way interlocking functions, which adopts the following technical scheme: The utility model provides a valve with auto-lock and two-way interlocking function, includes first valve body and second valve body, first valve body and second valve body structure are the same, just first valve body is used for dock with the second valve body, the one end of first valve body is equipped with the inlet, and the other end is equipped with the liquid outlet, just the inlet communicates with the liquid outlet, all be equipped with plugging device on first valve body and the second valve body, plugging device includes shutoff ball, actuating mechanism, locking mechanism and interlocking mechanism, the shutoff ball is located first valve body, just the shutoff ball is located between inlet and the liquid outlet, just the shutoff ball is used for cutting off inlet and liquid outlet, offer the through-hole that switches on inlet and liquid outlet on the shutoff ball, actuating mechanism and locking mechanism all install on first valve body, just actuating mechanism links to each other with the ball, just actuating mechanism is used for driving the shutoff ball and rotates to make the through-hole switch on inlet and liquid outlet, locking mechanism links to each other with actuating mechanism, interlocking mechanism installs in first valve body, just the shutoff ball links to each other with first valve body, and still interlock with the interlock mechanism on the first valve body. Through adopting above-mentioned technical scheme, through set up plugging device on first valve body and second valve body, when first valve body and second valve body are not connected, rely on the shutoff ball to close first valve body or second valve body, and lock actuating mechanism through locking mechanism, thereby reduce the shutoff ball and switch on the condition of first valve body or second valve body, simultaneously, rely on interlocking mechanism to further carry out spacingly to the rotation of shutoff ball, thereby realize the double locking to the shutoff ball, and because interlocking mechanism's existence, make first valve and second valve only when accomplishing the concatenation, just can make interlocking mechanism release the locking to the shutoff ball, thereby reduce the problem that the maloperation leads to the valve to be opened. In a specific embodiment, the driving mechanism includes a handle, a mandrel and an upper cover, the mandrel is mounted on the first valve body, one end of the mandrel penetrates through the side wall of the first valve body and extends into the first valve body, one end of the mandrel located in the first valve body is connected with the plugging ball, the upper cover is mounted on one end of the mandrel located outside the first valve body, and one end of the handle is mounted on the upper cover. Through adopting above-mentioned technical scheme, through the rotation of drive handle to drive the upper cover and rotate, make the upper cover drive the dabber and rotate, thereby make the dabber can drive the shutoff ball and rotate, make the through-hole on the shutoff ball communicate inlet and liquid outlet, thereby realize opening of first valve body or second valve body. In a specific implementation manner, the first valve body and the second valve body are respectively
