[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 The pneumatic tilting kettle bottom valve shown comprises a valve body 1, which is used to carry a main body for mounting internal components of the pneumatic tilting kettle bottom valve;

[0029] The valve pipe 2 is arranged on one side of the outside of the valve body 1 for medium circulation, and a docking flange 3 is fixedly installed on the outside of the valve pipe 2, and a docking hole 4 is opened on the outside of the docking flange 3;

[0030] The mounting ring 8 is arranged inside the valve tube 2 and is used to add non-return capability to the pneumatic tilting kettle bottom valve, and a fixing bolt 9 is passed through the outside of the mounting ring 8, one end of the fixing bolt 9 is movably connected with a reflux ring 10, one side of the reflux ring 10 is provided with an embedded groove 11, a torsion spring 12 is fixedly installed on the outside of the reflux ring 10, a reflux plug 13 is fixedly installed on one end of the torsion spring 12, and an embedded block 14 is fixedly installed on one side of the reflux plug 13;

[0031] The metal valve seat 20 is arranged above the valve body 1 and is used for connecting with the inclined pneumatic controller 23. A stuffing box 21 is fixedly installed above the metal valve seat 20. An upper pressure plate 22 is fixedly installed above the stuffing box 21. An inclined pneumatic controller 23 is arranged above the upper pressure plate 22. When the medium refluxes, the reflux plug 13 is pushed in the reverse direction by the medium, driving the torsion spring 12 to expand and contract. The reflux plug 13 and the embedded block 14 are stuck in the embedded groove 11 of the reflux ring 10, realizing one-way closure of the valve pipe 2 to complete the purpose of non-return, and then the pneumatic inclined kettle bottom valve is closed in time through the inclined pneumatic controller 23.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a stud bolt 5 penetrates the bottom of the valve body 1, one end of the stud bolt 5 is movably connected to a valve cover 6, and the outside of the stud bolt 5 is movably connected to a tightening nut 7. The structure of the valve cover 6 and the tightening nut 7 is simple, which is convenient for disassembling the valve body 1 after long-term use, and the pneumatic tilting kettle bottom valve is regularly cleaned to ensure the circulation of the medium. The number of torsion springs 12 is set to be multiple, and the multiple torsion springs 12 are evenly spaced on the reflux ring 10. Regardless of whether the gas or fluid medium passes through the valve pipe 2, it will push the reflux plug 13 and the torsion spring 12 drives the reflux plug 13 to extend, so that the reflux plug 13 is separated from the reflux ring 10 and leaks a gap in the valve pipe 2, so that the medium can flow normally.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, a sealing groove 15 is provided inside the valve body 1, and a cylindrical spring 16 is arranged inside the sealing groove 15. A sealing ring 17 is fixedly installed on one end of the cylindrical spring 16. The sealing ring 17 arranged outside the ball 18 can directly contact the outside of the ball 18 under the drive of multiple groups of cylindrical springs 16, thereby blocking the gap between the ball 18 and the inside of the valve body 1. The number of cylindrical springs 16 is set to be multiple, and the multiple cylindrical springs 16 are evenly spaced on the sealing ring 17. When the pneumatic tilting kettle bottom valve is in a closed state, the cooperation of the sealing ring 17 and the ball 18 allows the device to have good sealing performance and reduce leakage of the medium. A ball 18 is arranged on one side of the sealing ring 17, and a valve stem 19 is fixedly installed above the ball 18. The ball 18 has a simple structure and is easy to operate. If a fault occurs, it also reduces the maintenance difficulty of maintenance personnel, which facilitates timely maintenance of the pneumatic tilting kettle bottom valve.

[0034] The working principle of the utility model is as follows: firstly, an external power supply is connected, the pneumatic tilting kettle bottom valve is taken out, and the device is connected to an external pipeline through the valve tube 2, the docking flange 3 and the docking hole 4, and then the ball 18 and the valve stem 19 are driven to rotate through the tilting pneumatic controller 23 to allow the pneumatic tilting kettle bottom valve to circulate normally. Then, when the medium flows into the pneumatic tilting kettle bottom valve, the mounting ring 8 and the reflux ring 10 are installed inside the inlet valve tube 2. In this way, no matter whether the gas or fluid medium passes through the valve tube 2, it will push the reflux plug 13 and the torsion spring 12 will drive the reflux plug 13 to extend, so that the reflux plug 13 is separated from the reflux ring 10 and leaks a gap in the valve tube 2, so that the medium can circulate normally. Subsequently, when the medium refluxes, the reflux plug 13 is pushed in the opposite direction by the medium, driving the torsion spring 12 to expand and contract, and the reflux plug 13 and the embedded block 14 are stuck in the embedded groove 11 of the reflux ring 10, realizing a one-way sealing of the valve tube 2. The purpose of check is achieved by closing. In this way, the pneumatic tilting kettle bottom valve can be used in the chemical, pharmaceutical and other industries to effectively prevent the medium from flowing back in the pipeline. The pneumatic tilting kettle bottom valve is then closed in time through the tilting pneumatic controller 23. At the same time, when the pneumatic tilting kettle bottom valve is in use, the sealing ring 17 arranged on the outside of the ball 18 can be driven by multiple groups of columnar springs 16 to directly contact the outside of the ball 18. In this way, the gap between the ball 18 and the inside of the valve body 1 is blocked, so that when the pneumatic tilting kettle bottom valve is in a closed state, the cooperation of the sealing ring 17 and the ball 18 allows the device to have good sealing performance and reduce the leakage of the medium. Finally, after completing the installation and use of all the pneumatic tilting kettle bottom valves according to the above operations, turn off the switch of the tilting pneumatic controller 23. If it is not used for a long time, cut off the external power supply. In this way, the use process of the pneumatic tilting kettle bottom valve is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
