Description

Technical Field

[0001] This utility model relates to the field of threaded plug technology, and in particular to a novel hydraulic valve threaded plug. Background Technology

[0002] With the increasing automation of coal mining, intelligent underground coal mining faces are developing rapidly. Hydraulic directional valves are key components of the electro-hydraulic control system in automated equipment, comprising valve seats, valve cores, and plugs. Hydraulic directional valves also have the highest failure rate in the entire electro-hydraulic control system, requiring frequent disassembly of the valve core for cleaning and maintenance.

[0003] While existing split-type hydraulic directional valve threaded plugs solve the problem of seal damage or failure caused by rotational friction between the seal and the valve seat, after prolonged use, the drive groove of the nut is prone to splintering, making it difficult to rotate the plug out.

[0004] Therefore, it is necessary to provide a new type of hydraulic valve threaded plug to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a novel threaded plug for hydraulic valves, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel hydraulic valve threaded plug, including a nut, a drive column, a set screw, a sealing cap, and a valve core plug. The nut end face is provided with a drive column, the drive column end face is provided with a sealing cap, the sealing cap end face is provided with a set screw, and the set screw end face is provided with a valve core plug. A insertion hole is provided through the circumferential side of the drive column. By providing a drive column with an insertion hole on its circumferential side, after the drive groove on the nut end face is threaded, a stainless steel body can be inserted through the insertion hole, and then the stainless steel body can be driven to rotate the drive column, thereby causing the set screw to rotate out of the hydraulic valve. This method is simple to operate, convenient to perform, and avoids locking. The sealing cap ensures that when the set screw rotates and seals with the hydraulic valve, the sealing cap fits tightly against the surface of the hydraulic valve. This method not only limits the stroke of the set screw but also improves its sealing performance through the limiting effect of the sealing cap.

[0007] Preferably, a drive groove is formed on the surface of the other end of the nut.

[0008] Preferably, there are two insertion holes, and the two insertion holes are perpendicularly formed on the drive column.

[0009] Preferably, the outer diameter of the sealing cap is larger than the outer diameter of the set thread post.

[0010] Preferably, the nut, drive post, set thread post, sealing cap, and valve core plug are integrally formed.

[0011] Preferably, the nut, drive post, set thread post, sealing cap, and valve core plug are made of stainless steel.

[0012] Compared with related technologies, the novel hydraulic valve threaded plug provided by this utility model has the following beneficial effects:

[0013] Compared with existing technologies, this new type of hydraulic valve threaded plug features a drive column with insertion holes on its circumferential side. After threading the drive groove on the nut end face, a stainless steel body can be inserted through the insertion hole, and then driven to rotate the drive column, causing the set screw to rotate out of the hydraulic valve. This method is simple to operate, easy to use, and avoids locking. Furthermore, the sealing cap ensures a tight seal between the set screw and the hydraulic valve surface during rotational sealing. This not only limits the stroke of the set screw but also improves sealing performance through the sealing cap's limiting effect.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] Please refer to the following: Figure 1-3A novel hydraulic valve threaded plug includes a nut 1, a drive post 2, a set screw post 4, a sealing cap 3, and a valve core plug 5. The drive post 2 is located on the end face of the nut 1, the sealing cap 3 is located on the end face of the drive post 2, the set screw post 4 is located on the end face of the sealing cap 3, and the valve core plug 5 is located on the end face of the set screw post 4. A insertion hole 6 is provided through the circumferential side of the drive post 2. By providing the drive post 2 and the insertion hole 6 on its circumferential side, after the drive groove 7 on the end face of the nut 1 is threaded, the operator... A stainless steel body can be found, and then the insertion hole 6 can be inserted through it. The stainless steel body can then be driven to rotate the drive column 2, thereby causing the set screw 4 to rotate out of the hydraulic valve. This method is simple to operate and easy to operate, avoiding the situation of locking. By setting a sealing cover 3, when the set screw 4 rotates and seals with the hydraulic valve, the sealing cover 3 can be tightly attached to the surface of the hydraulic valve. This method can not only limit the stroke of the set screw 4, but also improve its sealing performance through the limiting effect of the sealing cover 3.

[0023] The working principle of the novel hydraulic valve threaded plug provided by this utility model is as follows:

[0024] This novel hydraulic valve threaded plug, by setting a drive column 2, has an insertion hole 6 on its circumferential side. After the drive groove 7 on the end face of the nut 1 is threaded, the operator can find a stainless steel body, pass it through the insertion hole 6, and then drive the stainless steel body to rotate the drive column 2, thereby causing the set threaded column 4 to rotate out of the hydraulic valve. This method is simple to operate and easy to operate, avoiding the possibility of locking. Secondly, by setting a sealing cover 3, when the set threaded column 4 rotates and seals with the hydraulic valve, the sealing cover 3 can be tightly attached to the surface of the hydraulic valve. This method can not only limit the stroke of the set threaded column 4, but also improve its sealing performance through the limiting effect of the sealing cover 3.
