[0003] The current push one-way lock includes a valve body and a valve sleeve built in the valve body, a valve core, a valve seat and a push rod. It is inserted into the unloading cavity of the valve seat to interact with the head of the valve core. There are also four interfaces on the valve body for connecting with other components. This structure has many one-way lock parts, which will lead to more cumbersome assembly. , and it will lead to inconvenient maintenance, low service life, and easy to affect production

The invention discloses a sliding one-way lock which comprises a valve body, a valve bush and a hydraulic assembly arranged in a valve cavity of the valve body. The hydraulic assembly comprises a valve element, a valve seat and an ejector rod. The valve seat is provided with a liquid passing cavity. The head of the ejector rod stretches into the liquid passing cavity of the valve seat. The head of the valve element is connected with the valve seat in a sealed mode at the portion of an end opening, communicated with the liquid passing cavity, of the valve seat. The ejector rod is sleeved with a reset spring. A head rod body of the ejector rod is provided with an external thread. A limiting block is arranged at the position, close to the liquid passing cavity, in the valve seat. A through hole is formed in the limiting block. An internal thread matched with the external thread on the ejector rod is arranged on the inner wall of the through hole. According to the sliding one-way lock, the valve seat and the ejector rod are in threaded connection, the ejector rod can be screwed into the liquid passing cavity in the valve seat to form the plug-in mounting type hydraulic assembly, the system integration degree of the whole one-way lock is high, the one-way lock is convenient to install and maintain, namely, installing is easy, maintenance is convenient, and the sliding one-way lock can be repaired by directly replacing the plug-in mounting type hydraulic assembly.
Description
technical field [0001] The invention relates to a hydraulic component in a hydraulic circuit of a coal mine hydraulic support, in particular to a push one-way lock. Background technique [0002] The push one-way lock is a control element that controls the opening and closing of the one-way valve in the hydraulic system. It mainly plays the role of controlling the support and unloading of the single-acting cylinder in the hydraulic support. It is generally used on the telescopic jack, because this structure It can maintain the one-way liquid inlet to keep the one-way action of the oil cylinder under pressure. At the same time, when it is required to retract, the valve core is opened through the action of the hydraulic control port on the one-way lock, and the valve core is stably retracted. [0003] The current push one-way lock includes a valve body and a valve sleeve built in the valve body, a valve core, a valve seat and a push rod. It is inserted into the unloading cavit...
