[0027] The utility model embodiment provides a valve connecting flange quick-installation structure.

[0028] See also Figure 1 , including a three-way valve 1, the top surface of the three-way valve 1 is threadedly connected with a control knob 10, the three-way valve 1 is a prior art and will not be described in detail in this application. Turning the control knob 10 can control the flow rate of the material inside the three-way valve 1, so that the staff can adjust the material delivery efficiency according to needs.

[0029] See also Figure 1 and Figure 2 A delivery pipeline 2 is arranged outside the three-way valve 1, and flanges 3 are fixedly connected to the ends of the three-way valve 1 and the delivery pipeline 2. The delivery pipeline 2 plays the role of conveying materials. The flange 3 can fix the three-way valve 1 and the delivery pipeline 2 together. A sealing gasket is installed at the joint of the two flanges 3 to prevent the transported materials from leaking to the outside through the gap between the flanges 3.

[0030] See also Figure 3A push ring 4 is arranged on the outside of the three-way valve 1, and a threaded nail 9 is connected to the internal thread of the push ring 4. The push ring 4 includes an upper and a lower part, one end of the two parts is hinged by a pin box, and the other end is provided with a threaded hole. The staff can open the push ring 4 or fix the push ring 4 together by rotating the threaded nail 9.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A group of fixing bolts 5 are fixedly connected to the outer surface of the pushing ring 4, and a fixing ring 6 is arranged on the outside of each fixing bolt 5. Each fixing ring 6 is fixedly connected to the flange 3. Through the arrangement of the pushing ring 4 and the fixing bolts 5, it is convenient for the staff to push multiple fixing bolts 5 into the through holes of the flange 3 at the same time, reducing the work intensity of the staff to insert the fixing bolts 5 into the through holes one by one, thereby improving work efficiency.

[0032] See also Figure 3 , Figure 4 and Figure 5 Two fixing mechanisms 7 are arranged inside each fixing ring 6, and a socket 8 is opened on the outer surface of each fixing bolt 5, and each socket 8 is slidably connected with the corresponding clamping column 703. When the staff pushes the propulsion ring 4, the fixing bolt 5 will enter the through hole of the flange 3. When the fixing bolt 5 slides to a certain position in the through hole, the clamping column 703 will slide into the socket 8 and plug into the socket 8, thereby limiting the fixing bolt 5, so that the fixing bolt 5 remains fixed in the through hole inside the flange 3, and the quick connection between the two sets of flanges 3 is completed.

[0033] See also Figure 4 and Figure 5 The fixing mechanism 7 includes a connecting ring 701 fixedly connected to the fixing ring 6, and the bottom surface of the connecting ring 701 is fixedly connected to a fixing sleeve 702, and the outer surface of the fixing sleeve 702 is slidably connected to a clamping column 703. The bottom end of the clamping column 703 is a special-shaped column, which is generally a hemispherical shape with less resistance, and the other half is a vertical semi-cylindrical shape. Its purpose is to facilitate the fixing bolt 5 to slide in the through hole, so that the clamping column 703 can be squeezed to make the clamping column 703 slide upward. When the fixing bolt 5 slides to a specific position, the clamping column 703 will be reset under the elastic force of the reset spring 704, so as to be plugged into the socket 8.

[0034] A return spring 704 is sleeved on the outer surface of the fixed sleeve 702, and the two ends of the return spring 704 are fixedly connected to the connecting ring 701 and the clamping column 703 respectively. Through the setting of the return spring 704, space can be provided for the fixing bolt 5 to squeeze the clamping column 703 to slide up. At the same time, the elastic potential energy of the return spring 704 is sufficient to push the clamping column 703 to reset, so that the clamping column 703 can maintain a stable connection with the socket 8. Although the return spring 704 may shake slightly due to its own material problem, this is within the acceptable range of the device and will not affect the connection effect between the clamping column 703 and the socket 8.

[0035] The connecting ring 701 is slidably connected with a sliding connecting rod 705, which is fixedly connected to the clamping column 703. The sliding connecting rod 705 passes through the fixed sleeve 702 and is slidably connected to the fixed sleeve 702. The top surface of the sliding connecting rod 705 is fixedly connected with a pulling block 706. Through the setting of the sliding connecting rod 705, when the staff wants to remove the flange 3, they can pull the pulling block 706. The pulling block 706 is driven by the force to drive the sliding connecting rod 705 to slide up inside the fixed sleeve 702. The sliding connecting rod 705 slides up and drives the clamping column 703 to compress the reset spring 704, so that the clamping column 703 cancels the plug-in effect with the socket 8. At this time, pulling the pushing ring 4 can easily remove the fixing bolt 5 from the through hole, which greatly reduces the work intensity of disassembling and assembling the flange 3 and improves the work efficiency of disassembly and assembly.

[0036] A sliding groove 707 is provided inside the fixing ring 6, and the clamping column 703 is slidably connected to the sliding groove 707. The sliding groove 707 provides space for the clamping column 703 to be plugged into the socket 8. When the end of the fixing bolt 5 squeezes the hemispherical column at the bottom of the clamping column 703, the sliding groove 707 can limit the clamping column 703, so that the clamping column 703 is forced to slide upward inside the sliding groove 707. When the socket 8 moves to the bottom of the clamping column 703, the clamping column 703 will slide downward inside the sliding groove 707 under the push of the reset spring 704, thereby clamping with the socket 8. At this time, the fixing bolt 5 and the fixing ring 6 remain stable, thereby completing the fixed quick connection between the flanges 3.

[0037] Working principle: when the staff wants to connect the three-way valve 1 with the delivery pipe 2, first put the push ring 4 on the outside of the delivery pipe 2 and fix the push ring 4 through the threaded nail 9, and then push the push ring 4 to move toward the connecting flange 3. The movement of the push ring 4 drives multiple fixing bolts 5 to be inserted into the through holes opened on the flange 3. When the fixing bolts 5 squeeze the bottom end of the clamping column 703, the clamping column 703 will be compressed by the reset spring 704 to slide in the direction of the connecting ring 701. When the socket 8 moves to the bottom of the clamping column 703, the clamping column 703 will be reset under the elastic force of the reset spring 704, thereby clamping with the socket 8. At this time, under the action of the flange 3, the push ring 4, the fixing bolts 5 and the fixing ring 6, the three-way valve 1 and the delivery pipe 2 can be quickly connected together, avoiding the fixing operation of manually tightening multiple nuts, thereby improving the installation efficiency of the flange 3.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
