[0032] Among them, the positioning structure includes an arc-shaped metal sheet 601 and a guide installation groove 602; an annular groove is opened in the middle part of the four position limiting rings 6, and eight arc-shaped metal sheets 601 are arranged. Two arc-shaped metal sheets 601 are fixedly connected in a circular array in each annular groove, and the two arc-shaped metal sheets 601 are electrically connected to the sound and light alarm; a plurality of guide installation grooves 602 are arranged, and a plurality of guide installation grooves 602 are respectively arranged in a circular array on the inner side of the four position limiting rings 6; when leakage occurs between the four-way stopcock valve body 2 and the cooling pipeline, distilled water will enter the annular groove.

When installing the four-way plug valve body 2, the position limiting ring 6 is first clamped on the outer side of the flange of the cooling pipeline. At this time, the flange of the cooling pipeline will squeeze The arc surface of the pressure limiting plate 7 is pressed, so that the pressure limiting plate 7 slides outward along the position limiting ring 6. The outer side of the position limiting sleeve 704 is provided with an arc surface. When the position limiting sleeve 704 contacts the position limiting ring 6, the position limiting ring 6 will squeeze the arc surface of the position limiting sleeve 704, so that the position limiting sleeve 704 slides along the limiting guide rod 702. At this time, the connecting guide rod 705 will guide the movement of the position limiting sleeve 704. When the position limiting sleeve 704 slides, it will compress the fourth reset elastic member 703, so that the position limiting sleeve 704 is close to the pressure limiting plate 7, avoiding the position limiting sleeve 7 04 hinders the movement of the pressure limit plate 7. After the pressure limit plate 7 is completely moved to the inner side of the position limiting ring 6, the position limiting ring 6 will be smoothly stuck on the outer side of the flange of the cooling pipeline. At this time, the third reset elastic member 701 will push the pressure limit plate 7 to reset, so that the pressure limit plate 7 is blocked on the outer side of the flange of the cooling pipeline. The four-way stopcock valve body 2 is rotated to align the connecting hole of the connecting flange 5 with the connecting hole of the cooling pipeline flange. At this time, the fourth reset elastic member 703 will push the position limiting sleeve 704 to reset, so that the position limiting sleeve 704 is inserted into the connecting hole to limit the position of the four-way stopcock valve body 2.

[0034] Among them, the positioning structure also includes a position limiting baffle 603 and a first reset elastic member 604; a plurality of position limiting baffles 603 are provided, and the plurality of position limiting baffles 603 are respectively slidably connected to the inner sides of a plurality of guide mounting grooves 602; a plurality of first reset elastic members 604 are provided, and the plurality of position limiting baffles 603 are elastically connected to the four position limiting rings 6 through a plurality of first reset elastic members 604; when the bolt is inserted into the connecting hole, the position limiting baffle 603 is first pushed to one side so that the position limiting baffle 603 slides along the guide mounting groove 602, at which time the position limiting baffle 603 is no longer blocked on the outside of the connecting hole, and after the bolt is inserted, the position limiting baffle 603 is loosened, at which time the first reset elastic member 604 will push the position limiting baffle 603 to reset and block on the outside of the bolt, and the position limiting baffle 603 is stepped, which can limit the bolt so that the bolt will not fall out of the connecting hole.

[0035] Example 2: Please refer to Figures 4 to 8 As shown:

[0037] Among them, the limiting structure includes an anti-skid rubber sheet 605, a guide connecting ring 606, a position limiting plate 607, a limiting operation block 608, a guide connecting rod 609, a positioning rubber block 610 and a second reset elastic member 611; a plurality of anti-skid rubber sheets 605 are provided, and the plurality of anti-skid rubber sheets 605 are evenly distributed and bonded to the outside of the four position limiting rings 6; a plurality of guide connecting rings 606 are provided, and the four guide connecting rings 606 are respectively rotatably connected to the outside of the four position limiting rings 6; a plurality of position limiting plates 607 are provided, and the plurality of position limiting plates 607 are evenly distributed and fixedly connected to the four guide connecting rings 606; there are four limit operation blocks 608, which are fixedly connected to the outer sides of the four guide connection rings 606; there are eight guide connection rods 609, which are slidably connected to the middle parts of the four limit operation blocks 608; there are eight positioning rubber blocks 610, which are fixedly connected to the inner sides of the eight guide connection rods 609; there are eight second reset elastic members 611, which are elastically connected to the four limit operation blocks 608 through the eight second reset elastic members 611; when inserting When the bolt is tightened, the bolt will squeeze the position limiting sleeve 704, so that the position limiting sleeve 704 is close to the pressure limiting plate 7. At this time, the guide connecting rod 609 is pulled up to make the guide connecting rod 609 slide along the limiting operation block 608. When the guide connecting rod 609 slides, it will drive the positioning rubber block 610 to move away from the anti-slip rubber sheet 605, and push the limiting operation block 608 to make the guide connecting ring 606 rotate around the position limiting ring 6. One side of the position limiting plate 607 is provided with an arc surface. When the guide connecting ring 606 rotates, it will drive the position limiting plate 607 to move, so that the arc surface of the position limiting plate 607 squeezes the pressure limiting plate 7. After the pressure limit plate 7 is squeezed, it will drive the position limiting sleeve 704 to move outward. After the pressure limit plate 7 is completely moved to the inside of the position limiting ring 6, loosen the guide connecting rod 609 to allow the second reset elastic member 611 to push the positioning rubber block 610 to reset. At this time, the positioning rubber block 610 will be in close contact with the anti-slip rubber sheet 605 under the action of the second reset elastic member 611, thereby limiting the position of the position limiting plate 607 and the pressure limit plate 7. At this time, screw the bolts on the outside of the bolts to complete the installation of the four-way plug valve body 2.
