[0031] At least two limit steps 211 are symmetrically arranged on the top of the first spiral clamp 21, and at least two arc-shaped inclined surfaces 212 are arranged on the top of the first spiral clamp 21. The arc-shaped inclined surfaces 212 are connected to the limit steps 211 in a ring-shaped manner end to end; the second spiral clamp 22 arranged on the side wall of one end of the fixed connecting plate 12 has the same structure as the first spiral clamp 21; and the outer circle radius of the second spiral clamp 22 is set the same as that of the first spiral clamp 21, and the height of the limit steps 211 of the second spiral clamp 22 and the first spiral clamp 21 is the same.

[0032] It should be noted that, in this embodiment, the connecting sleeve 13 is sleeved on the outer wall of the fixed connecting plate 12 at both ends of the main valve body 11, wherein the annular side wall 132 on the side wall of the connecting sleeve 13 is hung on the outer wall of the fixed connecting plate 12 to offset a part of the weight of the connecting sleeve 13 itself, so as to facilitate the subsequent hole alignment operation of the installer;

[0033] Then the connecting sleeve 13 is rotated. At this time, the first spiral clamp 21 at one end of the connecting sleeve 13 and the second spiral clamp 22 at one end of the fixed connecting plate 12 are merged together during the rotation operation, and when the limiting steps 211 on the first spiral clamp 21 and the second spiral clamp 22 touch each other, the limiting steps 211 restrict each other and the connecting sleeve 13 cannot rotate.

[0034] like Figure 2 , 4 As shown in , 6, the main valve body 11, the two ends of the main valve body 11 are symmetrically provided with fixed connecting plates 12, the side wall of the fixed connecting plate 12 is sleeved with a connecting sleeve 13, the side wall of the connecting sleeve 13 is penetrated with a limiting tightening member 14, the limiting tightening member 14 passes through one side of the annular side wall 132, and there is no special position restriction; one end of the limiting tightening member 14 is provided with a twisting handle 141, the other end of the side wall of the limiting tightening member 14 is provided with a thread, and the other end of the limiting tightening member 14 is threadedly connected to the side wall of the connecting sleeve 13.

[0035] It should be noted that in this embodiment, the connection sleeve plate 13 and the fixed installation holes 131 on the fixed connection plate 12 arranged at corresponding positions during casting are naturally aligned successfully, and multiple sets of screws and nuts can be easily inserted into the holes for fixed connection without observing the positions between the holes.

[0036] In addition, when the connecting sleeve 13 cannot be rotated, the operator can form pressure on the side wall of the fixed connecting plate 12 by rotating the twist handle 141 on the limiting tightening member 14 and cooperating with the bottom threaded connection of the limiting tightening member 14, thereby assisting in positioning and effectively avoiding secondary movement of the connecting sleeve 13, which is more conducive to the installer to fix it.

[0037] like Figure 1 , 2As shown in 3, the main valve body 11 has fixed connecting plates 12 symmetrically arranged at both ends of the main valve body 11, the side wall of the fixed connecting plate 12 is sleeved with a connecting sleeve 13, and the limiting tightening member 14 passes through one side of the annular side wall 132 without any special position restriction; a plurality of fixed mounting holes 131 are penetrated through the side wall of one end of the fixed connecting plate 12, and the fixed mounting holes 131 of the fixed connecting plate 12 and the connecting sleeve 13 are arranged at corresponding positions; a plurality of sets of screws and nuts are arranged on the inner wall of the fixed mounting hole 131 and located on the connecting sleeve 13 and at both ends of the connecting sleeve 13.

[0038] It should be noted that in this embodiment, the valve serves as a connecting control component, and both ends of the valve need to be connected in various scenarios. In the schematic diagram of the device, when the installation operator installs and connects any end of the valve body 10, it is necessary to align the holes on the fixed connecting plate 12 and align the holes on the fixed connecting plate 12 to facilitate the connection of nuts and bolts.

[0039] The working principle of the utility model is:

[0040] In the utility model, the valve is used as a connection control component, and both ends of the valve need to be connected in various scenarios. In the schematic diagram of the device, when the installation operator installs and connects any end of the valve body 10, it is necessary to align the holes of the fixed connection plate 12 and align the holes on the fixed connection plate 12 to facilitate the connection of nuts and bolts;

[0041] In actual installation, the main valve body 11 is heavy due to its high material density and high requirements, which makes it inconvenient to operate the hole. In this device, the operator puts the connecting sleeve 13 on the outer wall of the fixed connecting plate 12 at both ends of the main valve body 11, wherein the annular side wall 132 on the side wall of the connecting sleeve 13 is hung on the outer wall of the fixed connecting plate 12, offsetting part of the weight of the connecting sleeve 13 itself, making it convenient for the installer to perform subsequent hole operations;

[0042] Then the installer rotates the connecting sleeve 13. At this time, the first spiral clamp 21 at one end of the connecting sleeve 13 and the second spiral clamp 22 at one end of the fixed connecting plate 12 are combined together during the rotation operation, and when the limiting clamping steps 211 on the first spiral clamp 21 and the second spiral clamp 22 touch each other, the limiting clamping steps 211 restrict each other, and the connecting sleeve 13 cannot rotate;

[0043] At this time, the connecting sleeve 13 set at the corresponding position during casting and the fixed installation holes 131 on the fixed connecting plate 12 are naturally aligned successfully, and there is no need to observe the positions between the holes, so that multiple sets of screws and nuts can be easily inserted into the holes for fixed connection; in addition, when the connecting sleeve 13 cannot be rotated, the operator can rotate the twist handle 141 on the limiting tightening member 14, cooperate with the bottom threaded connection of the limiting tightening member 14, and form pressure on the side wall of the fixed connecting plate 12, and assist in positioning to effectively avoid secondary movement of the connecting sleeve 13, which is more conducive to the installer to fix it.
