[0020] Example 1

[0021] like Figure 1 - Figure 3 As shown, a non-return type engine porous pressure regulating valve includes a valve body 1, an input port 2 is provided at one end of the valve body 1, an output port 3 is provided at the other end of the valve body 1, an adjusting cylinder 4 is fixedly installed on the top of the valve body 1, an adjusting rod 5 is threadedly connected to the adjusting cylinder 4, an annular groove 11 is fixedly installed inside the valve body 1, a blocking block 12 is provided inside the annular groove 11, a groove body 13 is symmetrically provided inside the blocking block 12, a driving spring 14 is fixedly installed inside the groove body 13, a limiting frame 15 is fixedly installed inside the valve body 1, and one end of the limiting frame 15 extends to the inside of the groove body 13. When using the non-return type engine porous pressure regulating valve, the pipelines are connected to the input port 2, the output port 3 and the bypass pipe 7 respectively, and the conveyed medium flows into the flow through the input port 2. After reaching the inside of the valve body 1, the medium will flow into the corresponding pipeline through the bypass pipe 7 and the output port 3 respectively. When the medium flows to the output port 3, the medium pressure will push the block 12 to move, and the limit frame 15 and the groove body 13 will cooperate to make the block 12 move smoothly. When the block 12 moves out of the annular groove 11, the annular groove 11 is no longer sealed, and the medium will flow through the annular groove 11 and flow to the outside through the output port 3. When the medium flow is no longer transported, the driving spring 14 resets and pushes the groove body 13 to move. When the groove body 13 moves, it will push the block 12 into the annular groove 11, and then the inside of the annular groove 11 will be re-sealed, thereby avoiding the backflow of the medium output from the output port 3, thereby achieving the purpose of preventing backflow.

[0022] Furthermore, an operating disk 6 is fixedly mounted on the top of the adjusting rod 5 , and the operating disk 6 is used to facilitate the rotation of the adjusting rod 5 .

[0023] Example 2

[0024] like Figure 1 、 Figure 2 and Figure 4As shown, the utility model proposes a non-return type engine multi-hole pressure regulating valve. Compared with the first embodiment, as another embodiment of the utility model, a bypass pipe 7 is provided under the valve body 1, and a through port 8 is provided on the bypass pipe 7. The medium entering the interior of the valve body 1 will flow into the interior of the bypass pipe 7 through the through port 8, and then through the pipeline connected to the bypass pipe 7, so that the medium flows to a predetermined location.

[0025] Furthermore, an annular block 9 is provided inside the adjusting cylinder 4, and a sealing block 10 corresponding to the through-port 8 is fixedly installed at the bottom of the annular block 9. The adjusting rod 5 is rotated by the operating disk 6, and the position of the adjusting rod 5 is moved through the adjusting cylinder 4. When the adjusting rod 5 moves, the annular block 9 is driven to move, and when the annular block 9 moves, the sealing block 10 is driven to move. After the sealing block 10 moves into the through-port 8, the through-port 8 is sealed, and the pressure of the conveying medium can be adjusted.

[0026] Working principle: When using this non-return type engine multi-hole pressure regulating valve, first, when using the non-return type engine multi-hole pressure regulating valve, the pipelines are connected to the input port 2, the output port 3 and the bypass pipe 7 respectively. After the transported medium flows into the valve body 1 through the input port 2, the medium will flow to the corresponding pipeline through the bypass pipe 7 and the output port 3 respectively. When the medium flows to the output port 3, the medium pressure will push the block 12 to move, and the limit frame 15 and the groove body 13 will cooperate to make the block 12 move smoothly. When the block 12 moves out of the annular groove 11, the annular groove 11 is no longer sealed, and the medium will flow through the annular groove 11 and flow to the outside through the output port 3. When the medium is no longer transported, the driving spring 14 resets and pushes the groove body 13 to move. When the groove body 13 moves, it will push the block 12 into the annular groove 11, and then the inside of the annular groove 11 will be re-sealed, thereby avoiding the backflow of the medium output from the output port 3, thereby achieving the purpose of non-return backflow.

[0027] Finally, the medium that enters the valve body 1 will flow into the bypass pipe 7 through the port 8, and then flow to the predetermined location through the pipeline connected to the bypass pipe 7. The adjusting rod 5 is rotated by the operating panel 6, and the position of the adjusting rod 5 is moved through the adjusting cylinder 4. When the adjusting rod 5 moves, the annular block 9 is driven to move, and when the annular block 9 moves, the sealing block 10 is driven to move. After the sealing block 10 moves into the port 8, the port 8 is sealed, thereby adjusting the pressure of the conveying medium.

[0028] This is the working principle of the non-return type engine porous pressure regulating valve.
