[0027] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The utility model provides an embodiment: a double-guide structure valve, including a valve seat 1, a valve stem 2 is arranged inside the valve seat 1, the top of the valve stem 2 is rotatably connected to a connecting block 3, one side of the bottom surface of the connecting block 3 is fixedly connected to a pressure rod 4, the bottom of the pressure rod 4 is fixedly connected to an insert block 5, the top of the valve seat 1 is fixedly connected to a clamping ring 6, one side of the clamping ring 6 is fixedly connected to a clamping plate 7, the middle part of the inserting block 5 is threadedly connected to a bolt 8, and the bolt 8 passes through the clamping plate 7.

[0029] During use, when the valve needs to be operated, the bolt 8 can be rotated to remove the pressure plate, and the plug block 5 can be pulled to rotate to separate the clamping plate 7. When the pressure rod 4 and the valve stem 2 are in a perpendicular state to each other, the pressure rod 4 can be pulled to drive the valve stem 2 to rotate, and then the valve can be opened and closed. When the operation is completed, the pressure rod 4 is flipped to make the plug block 5 enter between the railing clamping plate 7, and then the bolt 8 is reinstalled between the plug block 5 and the clamping plate 7. At this time, the rotation of the valve stem 2 can be limited by the cooperation between the plug block 5, the clamping plate 7 and the bolt 8, thereby preventing the valve stem 2 from being affected by accidental contact.

[0030] Reference Figure 2 , Figure 3 and Figure 4 , two clamping plates 7 are provided, and the inserting block 5 is located between the two clamping plates 7. The middle parts of the inserting block 5 and the two clamping plates 7 are provided with threaded holes, and the bolts 8 are located inside the threaded holes.

[0031] The rotation of the valve stem 2 can be limited by the cooperation among the clamping plate 7, the insert block 5 and the bolt 8.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The top surface of the valve stem 2 is fixedly connected with a connecting plate 9, and one side of the connecting block 3 is fixedly connected with a connecting shaft 10, and the connecting shaft 10 is rotatably connected to the connecting plate 9. A through hole is opened in the middle of the connecting plate 9, and the connecting shaft 10 is inside the through hole.

[0033] The connecting plate 9 and the pressure rod 4 can be installed through the connecting shaft 10.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The middle and upper part of the outer wall of the valve seat 1 is fixedly connected with a mounting seat 11, and the top of the mounting seat 11 is threadedly connected with a cover shell 12. The cover shell 12 is set to a colorless and transparent material.

[0035] By installing the cover 12 on the top of the mounting seat 11, the cover 12 can be used to protect the pressure rod 4 and the valve, and by setting the cover 12 to be a colorless and transparent material, it is convenient to directly observe the situation inside the cover 12, thereby improving the practicality of the device.

[0036] Working principle: When the valve needs to be operated, the cover 12 is first rotated to remove it from the top of the mounting seat 11, and then the bolt 8 is rotated and removed. At this time, the pressure plate can be pulled to rotate along the connecting axis 10 as the center of the circle, so that the plug 5 is separated from the card plate 7. When the pressure rod 4 and the valve stem 2 are perpendicular to each other, the valve stem 2 can be driven to rotate by pulling the pressure rod 4, so that the valve can be opened and closed. When the operation is completed, the pressure rod 4 is turned over to make the plug 5 enter between the railing card plate 7, and then the bolt 8 is reinstalled between the plug block 5 and the clamping plate 7. At this time, the rotation of the valve stem 2 can be limited by the cooperation between the plug block 5, the clamping plate 7 and the bolt 8, thereby preventing the valve stem 2 from being affected by accidental contact by personnel, and after the bolt 8 is installed, the cover shell 12 can be installed on the top of the mounting seat 11 by flipping it. At this time, the cover shell 12 can be used to protect the valve stem 2, and by setting the cover shell 12 to a colorless and transparent material, it is convenient to directly observe the situation inside the cover shell 12, thereby improving the practicality of the device.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
