Description

Novel hydraulic valve screw plug Technical Field The utility model relates to the technical field of threaded plugs, in particular to a novel hydraulic valve threaded plug. Background Along with the improvement of the automation degree of coal mining, the underground intelligent coal mining working face is advanced. The hydraulic reversing valve is a key component of an electrohydraulic control system in automatic equipment and comprises a valve seat, a valve core, a plug and the like. The hydraulic reversing valve is also the part with the highest failure rate in the whole electrohydraulic control system, and the valve core is required to be frequently disassembled for cleaning and maintenance. The existing split type hydraulic reversing valve thread plug solves the problem that the sealing element is damaged or fails due to rotation friction between the sealing element and the valve seat, but after the split type hydraulic reversing valve thread plug is used for a long time, the thread phenomenon easily occurs in a driving groove of a nut, and the plug is not easy to rotate. Therefore, it is necessary to provide a novel hydraulic valve threaded plug to solve the above technical problems. Disclosure of utility model The utility model provides a novel hydraulic valve threaded plug which solves the problems in the background technology. In order to solve the technical problems, the novel hydraulic valve thread plug comprises a nut, a driving column, a fastening thread column, a sealing cover and a valve core plug, wherein the driving column is arranged on the end face of the nut, the sealing cover is arranged on the end face of the driving column, the fastening thread column is arranged on the end face of the sealing cover, the valve core plug is arranged on the end face of the fastening thread column, the inserting hole is formed in the peripheral side face of the driving column in a penetrating manner, through the driving column, after the thread is formed in the peripheral side face of the driving column, a stainless steel main body can be found out by workers after the thread is formed in the driving groove of the end face of the nut, then the inserting hole is penetrated, and then the stainless steel main body is driven to drive the driving column to rotate, so that the fastening thread column is driven to rotate out of the hydraulic valve. Preferably, the surface of the other end of the nut is provided with a driving groove. Preferably, two plug holes are formed, and the two plug holes are vertically formed on the driving column. Preferably, the outside diameter of the sealing cover is larger than the outside diameter of the tightening thread post. Preferably, the nut, the driving column, the fastening thread column, the sealing cover and the valve plug are integrally formed. Preferably, the nut, the driving column, the fastening thread column, the sealing cover and the valve plug are made of stainless steel. Compared with the related art, the novel hydraulic valve threaded plug provided by the utility model has the following beneficial effects: Compared with the prior art, this kind of novel hydraulic valve screw plug, through setting up the actuating cylinder, the spliced eye has been seted up at the week side of actuating cylinder, make behind the drive groove filigree of nut terminal surface, the staff can find a stainless steel main part, then run through the spliced eye, afterwards drive stainless steel main part drive actuating cylinder rotatory, thereby it comes out from the inside rotation of hydraulic valve to drive tight screw thread post, this mode easy operation, be convenient for operate it, avoid appearing the dead condition of lock, secondly through setting up sealed lid, be convenient for when tight screw thread post and hydraulic valve rotary seal, can make the inseparable laminating of sealed lid at the hydraulic valve surface, this mode not only can carry out spacingly to the stroke of tight screw thread post, and through the spacing of sealed lid, can improve its leakproofness. None of the parts of the device are the same as or can be implemented using prior art. Drawings FIG. 1 is a schematic structural view of a novel hydraulic valve threaded plug provided by the utility model; FIG. 2 is a schematic diagram of a driving groove structure of a novel hydraulic valve threaded plug provided by the utility model; fig. 3 is a front view of a novel hydraulic valve threaded plug provided by the utility model.
