[0002] Diaphragm pressure regulators are key components in pneumatic systems, and their performance and stability directly impact the overall system's efficiency and reliability. Traditional pneumatic diaphragm pressure regulators often face a series of challenges during installation and use, such as complex component installation, poor sealing, and improper flow path design leading to pressure fluctuations and gas leaks. These issues not only increase system maintenance complexity and costs but can also cause unnecessary disruptions to production processes, impacting product quality and efficiency.

[0003] Specifically, there are often sharp corners or uneven connections at the intersection of flow channels. These design defects make it easy for fluids (such as glue) to be retained during the flow process, forming blockages and affecting the normal operation of the system. Utility Model Content

[0036] The housing 1 has a support rod 2 passing through it, a flat plate 3 is fastened to the support rod 2, and a plurality of screws are used to fasten the upper cover 5, the diaphragm 4 and the housing 1. A decorative plate 6, a hydraulic joint 7, a pressure regulating valve 8 and an air pipe joint 9 are installed on the upper cover 5;

[0037] The cylinder body 10 has a flood seal 11, a gasket, an ejector pin 13 and an upper pressure block 14 placed therein;

[0038] The housing 15 and the fixing seat 19 are assembled in the housing 15 through the gasket. The ball valve 18 is provided in the lower pressure block 20. The lower pressure block 20 and several O-rings 16 are installed in the housing 15. The screws pass through the lower pressure block 20, the O-ring 16, the spacer ring 17, and the housing 15 in sequence and are locked on the upper pressure block 14; the cylinder body 10 is screwed to the housing 15, the hydraulic joint 7 is installed on the tail cover, and the tail cover is screwed in the housing 15.

[0039] The hole elastic circlip 12 fixes the flood seal 11 and the gasket in the cylinder body 10.

[0040] The ejector pin 13 and the upper pressing block 14 are connected by thread glue.

[0041] The junction of the flow channels inside the shell 15 is in an arc shape, so as to achieve a smooth transition at the junction of the flow channels and prevent glue from being retained and causing blockage.

[0042] There are at least two O-rings 16 located in the flow channel of the housing 15. Double O-rings are added in the channels for adjusting the stroke of the upper and lower cavities to prevent the oil precipitated from the glue from entering the upper cavity, thereby reducing glue blockage.

[0043] The housing 15 is provided with a logo for easy routine maintenance.

[0044] When installing this structure, the support rod passes through the shell, and the flat plate is fastened to the support rod with screws. Then, the upper cover, diaphragm, and shell are fastened in sequence with screws. This completes the installation of component A.

[0045] Insert the fixing seat through the gasket and then into the housing. Install the ball valve into the lower pressure block and the two O-rings into the housing. Then, screw through the lower pressure block, O-ring, spacer ring, and housing in sequence to lock it to the upper pressure block to complete the installation of component B.

[0046] Place the pan seal and gasket into the cylinder block and secure them with a circlip. First, drip 2-3 drops of thread glue on the threads of the upper clamp. Then, assemble the ejector pin into the upper clamp, secure it, and place it into the cylinder block. This completes the installation of component C.

[0047] When assembly is required, simply connect and tighten the components together using the threads of the cylinder block and the housing. Install the hydraulic plug into the tail cap, tighten the outer threads of the tail cap to the inner threads of the housing, and then assemble component A, which screws the housing and cylinder block together. Finally, install the decorative panel, hydraulic connector, pressure regulating valve, and air pipe connector in sequence to complete the assembly process. This device is easy to assemble, has good sealing, long service life, and avoids glue clogging.

[0048] Working Principle: A support rod passes through the housing. Precise positioning and fastening ensure a secure connection between the rod and the housing. A diaphragm is installed on the rod and secured with a top cover to prevent gas leakage. This ensures a smooth transition at the intersection of the housing's flow channels, reducing resistance and fluid retention during flow, thereby effectively preventing clogging. Double O-rings are added to the travel adjustment channels of the upper and lower cavities of the flow channel to form a double sealing barrier. This design not only improves sealing performance but also effectively prevents impurities or precipitated oil in the fluid from penetrating non-target areas, further reducing the risk of clogging.

[0049] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
