DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] In an automatic hydraulic control system, a plurality of solenoid valve blocks need to be installed to accurately control the flow direction and pressure of hydraulic oil, so as to realize the stable operation of mechanical equipment. This embodiment selects one valve block installation point for detailed description, please refer to Figure 1 Figure 4 The utility model provides a technical scheme: a solenoid valve block, comprising the following steps:

[0023] As an embodiment of the application, further, the solenoid valve block of the utility model is prepared, including valve block 100, valve fixing part 200 and pipeline fixing part 300. Check whether the valve connecting port and pipeline connecting port of valve block 100 are damaged or impurities, ensure that the internal flow channel is unobstructed. Check whether the first interface 2001, second connecting port 2006, fixed sleeve 2003, sliding groove 2002, sliding ring 2005, thread 2004 and first sealing ring 2007 of valve fixing part 200 are intact. Check whether the semicircular plate 3001, fixed block 3002, bolt 3003 and second sealing ring of pipeline fixing part 300 are complete and defect-free.

[0024] As an embodiment of the application, further, the interface of the solenoid valve is cleaned to ensure that there is no oil stain and impurity. The second connecting port 2006 of valve fixing part 200 is inserted into the interface of the solenoid valve, because the outer diameter of second connecting port 2006 is less than the outer diameter of first interface 2001, and second connecting port 2006 can slide in the interface of the solenoid valve, so that the installer can easily adjust the position of the solenoid valve to align with the valve connecting port of valve block 100. After adjusting the position, the fixed sleeve 2003 is slid along the outside of the first interface 2001, because the sliding ring 2005 cooperates with the sliding groove 2002, so that the fixed sleeve 2003 can move smoothly. When the fixed sleeve 2003 moves to the outside of the interface of the solenoid valve, the fixed sleeve 2003 is connected by rotating the fixed sleeve 2003, using the thread 2004 on the inner wall of the fixed sleeve 2003 to engage with the thread on the outside of the interface of the solenoid valve, until the fixed sleeve 2003 is fastened. At this time, the first sealing ring 2007 is tightly attached between the second connecting port 2006 and the interface of the solenoid valve, effectively preventing fluid leakage.

[0025] ​As an embodiment of the present application, further, according to the outer diameter of the pipe to be connected, the pipe fixing member 300 is adjusted. First, the bolt 3003 is loosened, and the movable half-arc plate 3001 is slid so that the distance between the two half-arc plates 3001 is slightly greater than the outer diameter of the pipe. The pipe is placed on the pipe connecting port of the valve block 100 so that the pipe is located between the two half-arc plates 3001. Then, the half-arc plate 3001 is slid so as to tightly fit the outer wall of the pipe, and the bolt 3003 is tightened to fix the two half-arc plates 3001 through the fixing block 3002, thereby firmly fixing the pipe in the pipe connecting port. At this time, the second sealing ring of the pipe connecting port wall surface also tightly contacts the outer wall of the pipe, further enhancing the sealing performance of the pipe connecting portion.

[0026] As an embodiment of the present application, further, in subsequent equipment maintenance, when a certain electromagnetic valve needs to be replaced, only the fixing sleeve 2003 is loosened, and the second connecting port 2006 is pulled out of the electromagnetic valve interface, so that the electromagnetic valve can be quickly disassembled, greatly shortening the maintenance time and improving the availability of the equipment. Similarly, when the connecting pipe needs to be replaced or repaired, the bolt 3003 is loosened, and the half-arc plate 3001 is slid to easily disassemble the pipe.
