[0002] The pneumatic high-pressure regulating valve is an important part of a pneumatic actuator. It consists of a main air chamber and an auxiliary air chamber. When the input signal pressure increases, a negative pressure is generated in the auxiliary air chamber, causing the diaphragm to move and drive the piston to move. At the same time, the output force increases to make the actuator act, and it is widely used in the industrial field.

[0003] After retrieval, a pneumatic high-pressure regulating valve disclosed according to the patent publication number "CN205859186U" includes a regulating valve body. The regulating valve body includes a valve body, a valve core, a valve cover and a valve stem. The valve core is placed in the valve body. One end of the valve core is provided with a sleeve, and the water inlet and the water outlet are separated by the sleeve. The valve stem is placed in the valve cover. The valve cover is assembled with the valve body through bolts. One end of the valve stem is in contact with the valve core and is provided with a gasket. A pneumatic device is provided on the valve cover of the regulating valve body. This pneumatic high-pressure regulating valve not only has a simple structure and is convenient to use, but also adopts a cage-type throttling form to share the pressure difference, reducing cavitation, erosion and turbulent flow damage, and greatly improving the service life of the regulating valve.

[0004] During the assembly process of the above pneumatic high-pressure regulating valve, it is found that the upper valve body and the lower valve body are mainly assembled through the cooperation of bolts and nuts.

[0017] The following are specific embodiments of the present utility model and, in combination with the accompanying drawings, further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0018] As Figures 1-3 shown, a pneumatic high-pressure regulating valve convenient for assembly of the present utility model includes an upper valve body 1 and a lower valve body 2. A upper connecting block 4 is fixedly provided at the top end of the upper valve body 1, a lower connecting block 3 is fixedly provided at the top end of the lower valve body 2. Connecting grooves 5 are formed at the four corners of the top end of the lower connecting block 3. Connecting columns 6 are fixedly provided at the four corners of the bottom end of the upper connecting block 4. The connecting columns 6 are inserted and connected with the corresponding two sides. Telescopic T-shaped clamping blocks 13 are provided on both sides of the connecting columns 6. Card slots 12 are formed on both sides of the connecting grooves 5. The T-shaped clamping blocks 13 are engaged with the card slots 12.

[0019] Specifically, between the upper valve body 1 and the lower valve body 2, the connecting columns 6 provided at the four corners of the bottom end of the upper connecting block 4 are nested with the connecting grooves 5 formed at the four corners of the top end of the lower connecting block 3, and are fixedly clamped through the T-shaped clamping blocks 13 provided on both sides of the connecting columns 6 and the card slots 12 formed on both sides of the connecting grooves 5, replacing the traditional installation by matching bolts and nuts, effectively improving the convenience of assembly and disassembly of the upper valve body 1 and the lower valve body 2.

[0020] As Figure 1 、 Figure 2 and Figure 3 shown, for a pneumatic high-pressure regulating valve convenient for assembly of the present utility model, an installation groove 14 is formed at the bottom of the connecting column 6. The two T-shaped clamping blocks 13 are inserted and connected with both sides of the installation groove 14. A return spring 16 is fixedly installed between the two T-shaped clamping blocks 13.

[0021] Specifically, the two T-shaped clamping blocks 13 are reset by the return spring 16, so that the T-shaped clamping blocks 13 are fixedly engaged with the card slots 12.

[0022] Through holes with aligned positions are formed at the bottoms of the two T-shaped clamping blocks 13. A limiting rod 15 is inserted and connected between the two through holes. Both ends of the limiting rod 15 are fixedly connected with the groove walls of the installation groove 14.

[0023] Connecting rods 10 are rotatably connected to the tops of the two T-shaped clamping blocks 13. The tops of the two connecting rods 10 are rotatably connected to a fixing ring 9.

[0024] A fixing rod 8 is inserted through the center of the connecting column 6. The bottom end of the fixing rod 8 passes through the fixing ring 9 and is fixedly connected with a limiting block 11. The top end of the fixing rod 8 is fixedly connected with a dial ring 7.

[0025] Specifically, through the cooperation of the fixed rod 8 and the dial ring 7, the connecting rod 10 can be pulled to rotate, and by rotating the connecting rod 10, the T-shaped block 13 can be pulled to separate from the card slot 12.

[0026] A sealing gasket is provided at the connection between the lower connecting block 3 and the upper connecting block 4.

[0027] Specifically, through the provided sealing gasket, the sealing performance at the connection between the lower connecting block 3 and the upper connecting block 4 is effectively improved.

[0028] In specific implementation, when assembling between the upper valve body 1 and the lower valve body 2, first align the connecting columns 6 at the four corners at the bottom of the upper connecting block 4 with the connection slots 5 opened at the four corners of the lower connecting block 3. Then, manually pull up the dial ring 7 through the fixed ring 9. By pulling up the fixed rod 8, the connecting rod 10 is pulled to move upward. The connecting rod 10 rotates under the tension. By rotating the connecting rod 10, the T-shaped block 13 is pulled to move into the interior of the installation slot 14. When the T-shaped block 13 completely enters the interior of the installation slot 14, at this time, the connecting column 6 moves downward under the gravity of the upper valve body 1, so that the connecting column 6 is completely embedded into the interior of the connection slot 5. At this time, manually release the dial ring 7. At this time, the two T-shaped blocks 13 are pushed out by the reset spring 16 and are engaged and fixed with the card slots 12 opened on the slot wall of the connection slot 5. At this time, the fixed rod 8 is reset under the tension of the connecting rod 10, and the assembly of the upper valve body 1 and the lower valve body 2 is completed;

[0029] When disassembling between the upper valve body 1 and the lower valve body 2, manually pull up the dial ring 7. By pulling up the dial ring 7, the T-shaped block 13 is contracted and separated from the card slot 12. Then, separate the upper valve body 1 and the lower valve body 2 to complete the disassembly, replacing the traditional installation through the cooperation of bolts and nuts, effectively improving the convenience of the assembly and disassembly of the upper valve body 1 and the lower valve body 2.
