Further, described spool and the joint face of described valve body are provided with the first sealing member, described valve body and the joint face of described three-way body are provided with the second sealing member。
Further, described first sealing member and the second sealing member are specially O RunddichtringO。
Further, the material rubber of described O RunddichtringO or plastics。
Further, described elastic component is specially spring, and the two ends of described spring are against on the end face that described pressure regulation bar is corresponding with spool respectively。
Further, described pressure regulation bar is specially screw mandrel, and described locking member is nut, and described pressure regulation bar is all threadeded with described valve body, locking member。
Compared with prior art, Advantageous Effects of the present utility model:
This utility model slip casting pressure maintaining valve is arranged on the grouting port place of grouting pump, one end of three-way body is connected with grouting pump, the other end is connected with manometric blender, press grouting pressure during slip casting and rotate the pressure regulation bar pressure to needs, the size of this pressure is shown by Pressure gauge, when slip casting process there being superpressure phenomenon occur, under pressure, spool moves to pressure regulation bar one end, elastic component is in compressive state, the now inner space of the inner chamber of pressure relief opening joint and described three-way body, unnecessary serosity moves up and passes through pressure relief opening joint earial drainage, so that injected hole keeps continual and steady grouting pressure, ensure that the serosity injecting anchor pole is in voltage stabilizing state。This utility model simple in construction, design science is reasonable, and pressure regulation bar is threaded, and interim adjustment flexibly, arbitrarily can adjust between 0.1～0.5MPa；In addition valve inner and spool link are provided with the first sealing member of soft body structure so that seal spool is rigorous, and open flexibly。
