Two connection grooves 2 are provided and are respectively located on both sides of the valve plate 12. The connection groove 2 is close to the end of the housing 11.

[0032] Referring to Figure 1 、 Figure 2 and Figure 3 ,a butting platform 3 is provided at the end of the connecting pipe. The butting platform 3 is annular and is used to butt against the end of the housing 11. The butting platform 3 gradually connects with the connecting pipe in the direction away from the housing 11.

[0033] Referring to Figure 1 、 Figure 2 and Figure 3 ,it further includes a first sealing ring 4. The first sealing ring 4 is used to be sleeved between the connecting pipe and the housing 11 and is clamped in the butting platform 3 and the connection groove 2.

[0034] Referring to Figure 1 、 Figure 2 and Figure 3 ,it further includes a hoop 5. The hoop 5 is used to lock the first sealing ring 4 onto the connecting pipe and the housing 11.

[0035] When the airtight valve is inserted into the pipeline, the housing 11 is moved into the pipeline interface, and the port of the housing 11 is butted against the end of the pipeline. Subsequently, the first sealing ring 4 is sleeved between the connecting pipe and the housing 11 and is clamped in the butting platform 3 and the connection groove 2. Then, the hoop 5 is used to lock the first sealing ring 4 in the butting platform 3 and the connection groove 2, completing the installation of the airtight valve. The above installation process reduces the input cost of installing the airtight valve and the installation of the airtight valve is simple and convenient; and under the action of the hoop 5 and the first sealing ring 4, the sealing performance between the airtight valve and the connecting pipe is improved, reducing the possibility of the transported substance leaking from the connection.

[0036] Referring to Figure 4 and Figure 5 ,in the embodiment of this application, the valve plate 12 is rotatably arranged inside the housing 11. The rotation axis of the valve plate 12 is perpendicular to the axis direction of the housing 11. A driving device 6 for driving the valve plate 12 to rotate to open and close the housing 11 is provided on the housing 11; after the airtight valve is inserted into the pipeline, the valve plate 12 is driven to rotate by the driving device 6 to open and close the pipeline, and the operation is simple and convenient.

[0037] Referring to Figure 4 and Figure 5 In the embodiment of the present application, the driving device 6 includes a main shaft 61, a fixed arm 62, a connecting rod 63, a rotating arm 64 and a mounting seat 65. The mounting seat 65 is fixedly arranged on the valve plate 12. The main shaft 61 is rotatably arranged in the housing 11. One end of the fixed arm 62 is fixedly arranged in the housing 11, and the middle part of the fixed arm 62 is rotatably arranged on the main shaft 61. One end of the connecting rod 63 is hinged to the fixed arm 62, and the other end is hinged to the mounting seat 65. One end of the rotating arm 64 is fixedly arranged on the main shaft 61, and the other end is hinged to the mounting seat 65. The hinge axes of the connecting rod 63 and the rotating arm 64 are both parallel to the length direction of the main shaft 61. The main shaft 61, the fixed arm 62, the connecting rod 63 and the mounting seat 65 form a four-bar linkage 63 mechanism. The driving device 6 further includes a driving member for rotating the main shaft 61. By driving the driving member to drive the main shaft 61 to rotate, the main shaft 61 rotates to drive the rotating arm 64 and the rotating rod to rotate around their respective hinge axes, thereby driving the mounting seat 65 to rotate in the housing 11. The mounting seat 65 drives the valve plate 12 to rotate to open the pipeline, and the operation is simple and convenient.

[0038] Referring to Figure 6 and Figure 7 In the embodiment of the present application, the driving member includes a driving plate 66 arranged on the main shaft 61. The driving plate 66 is connected to the main shaft 61 through a key 67. A driving handle 68 is arranged on the driving plate 66. When the valve is opened, the driving handle 68 is rotated. The driving handle 68 drives the driving plate 66 to rotate. The driving plate 66 rotates to drive the main shaft 61 to rotate, and the main shaft 61 rotates to drive the valve plate 12 to rotate.

[0039] Referring to Figure 6 and Figure 7 In the embodiment of the present application, a disc 69 is fixedly arranged outside the housing 11. The driving plate 66 is located outside the disc 69.

The pressing ring 612 is used to drive the driving plate 66 to press against the disc 69. When locking the valve plate 12, the locking handle 610 is rotated. The locking handle 610 gradually enters the disc 69, and drives the pressing ring 612 to press against the driving plate 66, so that the driving plate 66 abuts tightly against the disc 69, and the rotation angle of the driving plate 66 is restricted, thereby locking the relative position of the valve plate 12.

[0040] Referring to Figure 4, in the embodiment of the present application, to improve the impact resistance of the valve plate 12, concave-convex textures 7 are provided on the surface of the valve plate 12. The concave-convex textures 7 are arranged in a circular pattern on the valve plate 12 and the diameter gradually decreases.

When the fixed arm 62 is installed, the fixed arm 62 passes through the installation hole 10 and is clamped in the installation cylinder 13 to complete the installation of the fixed arm 62. And under the action of the first O-ring 14, the sealing performance between the plug 9 and the installation cylinder 13 is improved.

[0043] Refer to Figure 6 , to improve the sealing performance between the plug 9 and the installation cylinder 13, an installation plate 15 is provided at the top of the installation cylinder 13. The installation plate 15 is buckled on the top of the installation cylinder 13 and fixed to the plug 9 by bolts. The installation plate 15 is buckled at the end of the installation cylinder 13 to close the end of the installation cylinder 13, thereby improving the sealing performance between the plug 9 and the installation cylinder 13 and reducing the possibility of the plug 9 falling out of the installation cylinder 13.

[0044] Refer to Figure 6 , in the embodiment of the present application, a bushing 16 is provided in the housing 11. The main shaft 61 is located in the bushing 16, and second O-rings are provided at both ends of the main shaft 61. The second O-rings are sleeved into the bushing 16.
