Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic valves, in particular to a bidirectional sealing integral pneumatic valve. Background Art

[0002] A pneumatic valve is a valve driven by compressed air. In daily life, a bidirectional sealed integral pneumatic valve is often needed.

[0003] In the prior art, when fixing the connecting pipe on the pneumatic valve, the pneumatic valve is generally fixed by bolts. Although this method can effectively fix the connecting pipe and the pneumatic valve, the installation process is time-consuming and labor-intensive, thereby reducing the installation efficiency of the connecting pipe. In addition, since pneumatic valves are generally used in dark and humid environments, after the pneumatic valve is used for a long time, the bolts may rust, etc., which will make the connecting pipe difficult to disassemble and assemble, thereby reducing the installation efficiency and disassembly efficiency of the connecting pipe.

[0028] The following will be combined with the drawings in the embodiments 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 in 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.

[0029] See also Figure 1 - Figure 6 As shown, this embodiment provides a bidirectional sealed integral pneumatic valve, including a pneumatic valve body 1, and also includes:

[0030] The two water inlet pipes 2 are both connected to the inside of the pneumatic valve body 1, and the outsides of the two water inlet pipes 2 are fixedly connected with a connecting plate 22;

[0031] Two connecting pipes 5 are respectively arranged inside the two water inlet pipes 2, and the outsides of the two connecting pipes 5 are fixedly connected with fixing plates 6;

[0032] Support frames 3 are respectively arranged outside the two water inlet pipes 2;

[0033] The fixing assembly is symmetrically arranged outside the two support frames 3 and is used to fix the connection plate 22 and the fixing plate 6, so as to fix the connection pipe 5 and the water inlet pipe 2;

[0034] The expansion components are respectively arranged inside the two fixing plates 6 and are used to improve the sealing between the fixing plates 6 and the connecting plates 22 , thereby further improving the sealing and stability of the connection between the water inlet pipe 2 and the connecting pipe 5 .

[0035] The above working principle: when it is necessary to fix and install the connecting pipe 5 and the pneumatic valve body 1, it is only necessary to first plug the connecting pipe 5 into the inside of the water inlet pipe 2. At this time, the connecting pipe 5 will drive the fixing plate 6 to move synchronously. When the fixing plate 6 is sleeved on the outside of the connecting plate 22, the fixing plate 6 and the connecting plate 22 are fixed by the fixing component. At this time, the connecting pipe 5 can be fixedly installed on the pneumatic valve body 1 without using tools such as bolts, which effectively improves the installation efficiency of the connecting pipe 5. After the fixing between the fixing plate 6 and the connecting plate 22 is completed, it is only necessary to use the expansion component to effectively fill the gap between the fixing plate 6 and the connecting plate 22, thereby further improving the sealing between the connecting plate 22 and the fixing plate 6 and the stability of the installation, and then effectively improving the sealing between the connecting plate 22 and the fixing plate 6 and the stability of the installation, thereby effectively improving the sealing between the connecting pipe 5 and the pneumatic valve body 1, preventing the pneumatic valve body 1 from leaking air or liquid during use, saving time and effort.

[0036] In order to conveniently perform fixed installation processing between the fixed disk 6 and the connecting disk 22, the fixing assembly includes a mounting block 4 symmetrically arranged outside the support frame 3, a sliding rod 14 is symmetrically arranged inside the mounting block 4, and the two ends of the plurality of sliding rods 14 are respectively fixedly connected to the two sides of the inner wall of the mounting block 4, a moving plate 15 is arranged inside the mounting block 4, and a guide groove for the movement of the sliding rod 14 is opened inside the moving plate 15, and the outer parts of the plurality of sliding rods 14 are all sleeved with a return spring 16, and the plurality of return springs 16 are all in contact between the moving plate 15 and the mounting block 4. The outside of the movable plate 15 is fixedly connected with a pull plate through a connecting rod 17. A plug-in rod 18 is symmetrically provided on the opposite side of each two movable plates 15. The contact surfaces of the multiple mounting blocks 4 and the support frame 3 are provided with guide grooves for the plug-in rod 18 to move. The opposite sides of the two fixed plates 6 are symmetrically provided with plug-in plates 13. The insides of the two connecting plates 22 are provided with guide grooves for the plug-in plates 13 to move. The insides of the multiple plug-in plates 13 are provided with guide grooves for the plug-in rod 18 to move. When it is necessary to fix the fixed plate 6 and the connecting plate 22, When installing, just pull the pull plate first, then the pull plate will drive the connecting rod 17 to move synchronously, and the connecting rod 17 will drive the moving plate 15 to move synchronously outside the sliding rod 14. During the movement of the moving plate 15, the reset spring 16 will be squeezed, and the moving plate 15 will also drive the plug-in rod 18 to move synchronously. At this time, the connecting pipe 5 is plugged into the inside of the water inlet pipe 2, and the connecting pipe 5 will drive the fixed plate 6 to move synchronously, and the fixed plate 6 will drive the plug-in plate 13 to move synchronously. When the fixed plate 6 is completely sleeved on the connecting plate 2 2, the plug-in plate 13 will also be synchronously plugged into the guide groove inside the connecting plate 22. At this time, the pull plate is released again, and the reset spring 16 is reset, driving the movable plate 15 to move synchronously. The movable plate 15 then drives the plug-in rod 18 to move synchronously. When the plug-in rod 18 is plugged into the guide groove inside the plug-in plate 13, the connecting plate 22 and the fixed plate 6 can be fixed. At this time, the connecting pipe 5 and the pneumatic valve body 1 can be installed without using tools such as bolts, which effectively improves the installation efficiency of the connecting pipe 5.

[0037] Considering that after fixing the fixing plate 6 and the connecting plate 22, it is necessary to improve the sealing performance between the fixing plate 6 and the connecting plate 22 and the stability of the installation, the expansion assembly includes an inflatable bag 7 respectively arranged inside the two fixing plates 6, the interiors of the two inflatable bags 7 are connected to the air inlet pipe 9, the air inlet ends of the two air inlet pipes 9 are connected to the balloon 8, the interiors of the two air inlet pipes 9 are provided with a one-way valve, the interiors of the two inflatable bags 7 are connected to the exhaust pipe 10, and the air outlet ends of the two exhaust pipes 10 are provided with a sealing cover 11. After the fixation between the disk 6 and the connecting disk 22 is completed, the balloon 8 is squeezed. At this time, the gas inside the balloon 8 will be transmitted to the inflatable bag 7 through the air inlet pipe 9. When the inflatable bag 7 is fully inflated, the gap between the fixed disk 6 and the connecting disk 22 can be filled. At this time, the inflatable bag 7 can be used to further improve the sealing between the fixed disk 6 and the connecting disk 22 after fixation and the stability of the installation. When the inflatable bag 7 is not needed, just open the sealing cover 11. At this time, the gas inside the inflatable bag 7 will be discharged through the exhaust pipe 10.

[0038] In order to effectively extend the service life of the inflatable bag 7 and the balloon 8, the exterior of the two balloons 8 and the inflatable bag 7 are coated with an anti-corrosion coating. Through the setting of the anti-corrosion coating, the balloon 8 and the inflatable bag 7 can be effectively protected against corrosion, thereby further extending the service life of the balloon 8 and the inflatable bag 7.

[0039] In order to further improve the sealing between the connecting pipe 5 and the pneumatic valve body 1, an annular fixing sleeve 12 is fixedly connected to the opposite side of the two fixing disks 6, and the outside of the two annular fixing sleeves 12 is provided with a sealing ring, and the inside of the two connecting disks 22 is provided with a guide groove for the movement of the annular fixing sleeve 12. When the fixing between the fixing disk 6 and the connecting disk 22 is completed, the annular fixing sleeve 12 will also be synchronously inserted into the guide groove inside the connecting disk 22. At this time, the annular fixing sleeve 12 and the sealing ring can effectively improve the sealing between the fixing disk 6 and the connecting disk 22, thereby effectively improving the sealing between the connecting pipe 5 and the pneumatic valve body 1, and preventing the pneumatic valve body 1 from leaking air and liquid during use.

[0040] In addition, in order to further improve the convenience and stability of installation between the fixed disk 6 and the connecting disk 22, the outside of the two fixed disks 6 are fixedly connected with multiple connecting blocks 19, and the outside of the multiple connecting blocks 19 are fixedly connected with positioning rods 20. The upper and lower surfaces of the two support frames 3 are symmetrically provided with fixing blocks 21, and the interiors of the multiple fixing blocks 21 are provided with guide grooves for the positioning rods 20 to move. When the fixing between the fixed disk 6 and the connecting disk 22 is completed, the fixed disk 6 will drive the connecting block 19 to move synchronously, and the connecting block 19 will drive the positioning rod 20 to be synchronously plugged into the interior of the fixing block 21. At this time, the positioning rod 20 and the fixing block 21 can be used to further improve the accuracy and stability of installation between the fixed disk 6 and the connecting disk 22.
