[0023] By the attached Figure 1 and attached Figure 3As shown, in this embodiment, the fixing sleeve 7 is fixed on the butt joint fitting 6, and there is a slot 8 for inserting the connecting pipe 5 between the fixing sleeve 7 and the butt joint fitting 6, and a plurality of positioning rods 9 are fixed on the connecting pipe 5 at equal intervals in the circumferential direction, and a positioning groove 10 for the positioning rod 9 to be embedded is provided on the inner wall of the fixing sleeve 7, and a through hole 12 for the positioning rod 9 to pass through is provided on the end surface of the fixing sleeve 7, and a limiting hole 14 is provided on the protruding end of the positioning rod 9, and a rotating plate 15 is installed on the fixing sleeve 7, and a limiting square rod 13 passes through the rotating plate 15 and the limiting hole 14, and a No. 1 limiting ring 18 is fixed on the limiting square rod 13, and a reset spring 19 is sleeved on the limiting square rod 13 and is located between the rotating plate 15 and the No. 1 limiting ring 18, and an end surface of the limiting square rod 13 close to the positioning rod 9 is an inclined surface, so when in use, the positioning groove 10 is used for positioning, and the butt joint fitting 6 is directly The installation of the instrument pipe valve body 1 can be completed by inserting it into the slot 8, so that the positioning rod 9 passes through the positioning groove 10 to position the installation of the instrument pipe valve body 1, and at the same time, prevent the instrument pipe valve body 1 from accidentally rotating. Since the end face of the limiting square rod 13 close to the positioning rod 9 is an inclined surface, when the positioning rod 9 applies force to the inclined surface of the limiting square rod 13, a component force will be generated to move the limiting square rod 13 toward the outside, and at the same time, the No. 1 limiting ring 18 will be driven to move to shrink the reset spring 19. When the limiting hole 14 moves to the position of the limiting square rod 13, the reset spring 19 releases the elastic force to reset the limiting square rod 13, and the limiting square rod 13 passes through the limiting hole 14 for limiting and fixing, ensuring the stability of the installation of the instrument pipe valve body 1, and preventing the instrument pipe valve body 1 from accidentally sliding. The stability is high, the direct plug-in installation is more convenient, and the structure is simple, the cost is low, and the damage rate is low.

[0030] Since one end face of the limiting square rod 13 close to the positioning plug rod 9 is an inclined surface, when the positioning plug rod 9 applies force to the inclined surface of the limiting square rod 13, a component force will be generated to move the limiting square rod 13 toward the outside, and at the same time drive the No. 1 limiting ring 18 to move to contract the reset spring 19. When the limiting hole 14 moves to the position of the limiting square rod 13, the reset spring 19 releases the elastic force to reset the limiting square rod 13. The limiting square rod 13 passes through the limiting hole 14 for limiting and fixing, ensuring the stability of the installation of the instrument pipe valve body 1 and avoiding accidental sliding of the instrument pipe valve body 1. It has high stability and direct plug-in installation, which is more convenient, simple in structure, low in cost and low in damage rate.
