[0025] An alignment assembly is mounted on the pressure control device 4 and is used to adjust the accuracy of the connection between the pressure control device 4 and the pressure control device end 5.

[0026] The fixing assembly is installed on the alignment assembly and is used to effectively fix the pressure control device 4 and the pressure control device end 5 after they are connected.

[0027] A ring sleeve 10 is fixedly provided at the end of the pressure control device end 5 corresponding to the pressure control device 4, and four groups of holes 12 distributed equidistantly in a ring shape are opened on the ring sleeve 10. If the pressure control device 4 and the pressure control device end 5 are to be disassembled, the round rod 17 is pulled so that the round rod 17 drives the limiting rod 15 to slide out of the limiting hole 8 and the hole 12.

[0028] A positioning seat 11 is fixedly provided at the top position of the end 5 of the pressure control device. A groove is provided on the side of the positioning seat 11 corresponding to the pressure control device 4. The annular plate 6 is slid on the pressure control device 4 so that the end of the plug plate 7 on the annular plate 6 can be movably inserted into the groove on the positioning seat 11.

[0029] The end of the pressure control device 4 corresponding to the pressure control device terminal 5 is provided with an annular groove 9 adapted to the ring sleeve 10, and the ring sleeve 10 is movably inserted in the annular groove 9. The outer wall of the pressure control device 4 is provided with four groups of limiting holes 8 adapted to the holes 12. The limiting holes 8 pass through the top inner wall of the annular groove 9. The annular sleeve 10 at the end of the pressure control device terminal 5 is inserted into the annular groove 9, and the pressure control device terminal 5 is rotated at the end of the pressure control device 4 until the four groups of holes 12 are synchronously aligned with the four groups of limiting holes 8.

[0030] The alignment component includes an annular plate 6 and an insert plate 7. An annular annular plate 6 is slidably sleeved on the pressure control device 4. A horizontal insert plate 7 is fixedly provided on one side of the annular plate 6. The insert plate 7 on the side of the annular plate 6 can be used to position the top cover 13 on the annular plate 6, which effectively reduces the time required to align the four groups of top covers 13 with the four groups of limit holes 8, thereby improving the efficiency during installation.

[0031] The fixing assembly includes a top cover 13, an adjusting spring 14, a limiting rod 15, a transverse groove 16 and a round rod 17. Four groups of vertical top covers 13 are fixedly installed on the outer surface of the annular plate 6. The top inner wall of the top cover 13 is fixedly provided with an adjusting spring 14. The inner wall of the top cover 13 is slidably connected with the limiting rod 15. The bottom of the adjusting spring 14 is fixedly connected to the top of the limiting rod 15. A vertical transverse groove 16 is opened on one side of the top cover 13. One side of the limiting rod 15 is fixedly connected to the limiting rod 15 near the top. The four groups of round rods 17 are vertical and are slidably engaged in the transverse groove 16. When the pressure control device 4 needs to be connected to the pressure control device end 5 after maintenance, the four groups of round rods 17 are first pulled to slide in the transverse groove 16 to the top of the transverse groove 16. The round rods 17 simultaneously drive the limiting rods 15 to slide upward in the top cover 13. At this time, the limiting rods 15 compress the adjusting springs 14 to shorten them and then retract the limiting rods 15 into the top cover 13.

[0032] The four groups of limiting rods 15 respectively penetrate the bottom of the annular plate 6 and are movably inserted into the four groups of holes 12 through the four groups of limiting holes 8. The four groups of round rods 17 are relaxed, and the adjusting springs 14 are used to push the limiting rods 15 to slide out of the top cover 13 by utilizing the elasticity of the adjusting springs 14. The round rods 17 slide in the transverse grooves 16 to cause the limiting rods 15 to slide out of the top cover 13. During the sliding process, the bottom of the limiting rod 15 is first inserted into the limiting hole 8 and then slides into the hole 12 until it fits with the bottom inner wall of the annular groove 9.

[0033] Working principle: When the maintenance is completed and the pressure control device 4 needs to be connected to the pressure control device end 5, first pull the four groups of round rods 17 respectively to make the round rods 17 slide in the transverse groove 16 to the top of the transverse groove 16, and the round rods 17 simultaneously drive the limit rods 15 to slide upward in the top cover 13. At this time, the limit rods 15 compress the adjustment spring 14 to shorten the adjustment spring 14, and then retract the limit rods 15 completely into the top cover 13, and then insert the ring sleeve 10 at the end of the pressure control device end 5 into the ring groove 9, and rotate the pressure control device end 5 at the end of the pressure control device 4 until the four groups of holes 12 are synchronously aligned with the four groups of limit holes 8. The annular plate 6 is slid on the control device 4, so that the end of the plug plate 7 on the annular plate 6 is movably inserted into the groove on the positioning seat 11, and then the four groups of round rods 17 are loosened, and the elasticity of the adjusting spring 14 is used to make the adjusting spring 14 push the limiting rod 15 to slide out of the top cover 13, and the round rod 17 slides in the transverse groove 16 to slide the limiting rod 15 out of the top cover 13. During the sliding process, the bottom of the limiting rod 15 is first inserted into the limiting hole 8 and then slides into the hole 12 until it fits with the bottom inner wall of the annular groove 9. If the pressure control device 4 and the pressure control device end 5 are to be disassembled, the round rod 17 is pulled to make the round rod 17 drive the limiting rod 15 to slide out of the limiting hole 8 and the hole 12. Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
