Description

Technical Field

[0001] This utility model relates to the field of anti-surge valve technology, and in particular to a quick-release anti-surge valve connecting pipe assembly. Background Technology

[0002] Anti-surge valves are indispensable key components in fluid machinery systems such as compressors. Their main function is to bypass or backflow some fluid by quickly opening or adjusting the valve opening when the system is at risk of surge, thereby preventing surge from damaging the equipment and ensuring the stable operation of the system. In practical applications, anti-surge valves need to be connected to upstream and downstream pipelines through piping assemblies to ensure smooth fluid flow.

[0003] However, traditional anti-surge valve connection assemblies still have the following problems: 1. When it is necessary to inspect or replace parts or perform system maintenance on traditional anti-surge valve connection assemblies, a lot of time and manpower are often required to disassemble and install the connections, which seriously affects maintenance efficiency and increases system downtime; 2. The internal structure of traditional anti-surge valve connection assemblies is simple, and the fluid is prone to turbulent flow when flowing through the connections. This not only causes energy loss and affects the operating efficiency of the system, but also easily leads to vibration problems caused by turbulence, which adversely affects the service life of the connection assembly and related equipment. Therefore, we have introduced a quick-release anti-surge valve connection assembly. Utility Model Content

[0004] The main purpose of this utility model is to provide a quick-release anti-surge valve pipe assembly, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-release anti-surge valve connector assembly includes a main connector. A quick-release structure is movably sleeved on the right end of the main connector. The upper and lower parts of the outer surface of the quick-release structure are threaded with quick-release buckles. Several bolts are threaded at the left edge of the quick-release structure. Nuts are threaded on the outer surfaces of the bolts. A filter structure is fixedly connected to the right end of the quick-release structure by bolts and nuts.

[0007] Preferably, the quick-release structure includes an inner tube, with several retaining strips fixedly connected to the outer surface of the inner tube. A first flange is fixedly connected to the right end of the inner tube, and an outer tube is fixedly connected to the left end of the first flange. The upper and lower parts of the outer surface of the first flange are provided with second quick-release screw holes that pass through both the inner and outer sides. The upper and lower parts of the outer surface of the inner tube are provided with third quick-release screw holes. Several first fixing screw holes that pass through both the left and right sides are provided at the left edge of the first flange. A sealing gasket is fixedly connected to the right edge of the first flange.

[0008] By adopting the above technical solution, the cooperation of the inner tube, the clamping strip, and the outer tube facilitates quick positioning and connection with the main pipe, and the sealing gasket enhances the connection sealing performance, thereby improving the assembly convenience and sealing performance of the components.

[0009] Preferably, the main connecting pipe includes an anti-surge valve outlet pipe, the inner wall of which has several slots, and the upper and lower outer surfaces of which both have a first quick-release screw hole that passes through both the inner and outer sides.

[0010] By adopting the above technical solution, the slot and first quick-release screw hole of the anti-surge valve outlet pipe are adapted to the quick-release structure's clip and quick-release buckle, providing conditions for the quick connection and fixation of the two, and simplifying the connection operation.

[0011] Preferably, the inner tube is movably sleeved inside the outlet pipe of the anti-surge valve and is in close contact with the inner wall surface of the outlet pipe of the anti-surge valve; several of the retaining strips are movably sleeved in corresponding several retaining slots and are in close contact with the inner wall surface of corresponding several retaining slots; and the outer tube is movably sleeved on the outlet pipe of the anti-surge valve and is in close contact with the outer surface of the outlet pipe of the anti-surge valve.

[0012] By adopting the above technical solution: the tight-contact socket method, the stability of the connection between the main pipe and the quick-release structure is ensured, fluid leakage is effectively prevented, and the two are easy to assemble and disassemble quickly.

[0013] Preferably, the outer surfaces of the two quick-release buckles are threadedly connected to the inner wall surfaces of the corresponding two second quick-release screw holes, and extend through the corresponding two first quick-release screw holes into the corresponding two third quick-release screw holes.

[0014] By adopting the above technical solution, the quick-release structure and the main pipe can be quickly locked and released by threaded connection through the corresponding second quick-release screw hole, first quick-release screw hole and third quick-release screw hole, which greatly improves the efficiency of component assembly and disassembly and reduces operation time.

[0015] Preferably, the filter structure includes a second flange, a guide pipe is fixedly connected to the right end of the second flange, a downstream pipe fixing flange is fixedly connected to the right end of the guide pipe, a plurality of second fixing screw holes are opened at the left edge of the second flange, a plurality of third fixing screw holes are opened at the right edge of the downstream pipe fixing flange, a spiral guide plate is fixedly connected to the left side of the inner wall of the guide pipe, and a filter screen is fixedly sleeved on the right side of the guide pipe.

[0016] By adopting the above technical solution: the spiral guide plate guides the fluid to flow in an orderly manner, reducing turbulence and pressure loss, and the filter screen filters out impurities, protecting downstream equipment.

[0017] Preferably, the outer surfaces of the plurality of bolts are threadedly connected to the inner wall surfaces of the corresponding plurality of first fixing screw holes and extend into the corresponding plurality of second fixing screw holes.

[0018] By adopting the above technical solution, the bolt passes through the corresponding first and second fixing screw holes and is matched with the nut to achieve a stable connection between the quick-release structure and the filter structure, ensuring the reliability of the connection between the two, while making disassembly convenient and facilitating the maintenance and replacement of parts.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. During installation, this utility model only requires aligning the inner tube of the quick-release structure with the outlet pipe of the anti-surge valve on the main pipe, so that the inner tube, the clip, and the outer tube are respectively fitted with the outlet pipe and the slot of the anti-surge valve. Then, the quick-release buckle is passed through the second quick-release screw hole, the first quick-release screw hole, and extended into the third quick-release screw hole for fixation. Subsequently, the filter structure is connected to the quick-release structure with bolts and nuts. Finally, it is connected to the downstream pipe through the downstream pipe fixing flange. The entire installation process is simple and quick. During disassembly, first disconnect the downstream pipe from the downstream pipe fixing flange, unscrew the nuts and bolts to separate the quick-release structure and the filter structure, then rotate the quick-release buckle to release it, and finally remove the quick-release structure from the main pipe. This greatly simplifies the disassembly and assembly steps, reduces the time and manpower required for disassembly and assembly, improves maintenance efficiency, and shortens the system downtime.

[0021] 2. During use, the fluid flows out of the anti-surge valve outlet pipe of the main pipe and enters the inner pipe of the quick-release structure. After passing through the first flange, it enters the guide pipe of the filter structure. The spiral guide plate on the left side of the inner wall of the guide pipe can guide the fluid to form a spiral flow, making the fluid flow in the pipe more orderly and effectively reducing the occurrence of turbulence. At the same time, this orderly flow state reduces the energy loss of the fluid during the flow process, reduces pressure loss, and improves the operating efficiency of the system. In addition, the spiral flow can also reduce the vibration caused by turbulence, which is conducive to extending the service life of the pipe assembly and related equipment.

Several through-hole first fixing screw holes 27 are formed at the left edge of the first flange 23. A sealing gasket 28 is fixedly connected to the right edge of the 23; the main pipe 1 includes an anti-surge valve outlet pipe 11, the inner wall of which has several slots 12, and the upper and lower outer surfaces of the anti-surge valve outlet pipe 11 each have a first quick-release screw hole 13 that passes through both the inside and outside; the inner pipe 21 is movably sleeved inside the anti-surge valve outlet pipe 11 and is in close contact with the inner wall of the anti-surge valve outlet pipe 11, and several retaining strips 22 are respectively movably sleeved in the corresponding slots 12 and respectively engage with the corresponding retaining strips 12. The inner wall of the groove 12 is in close contact with the outer tube 24, which is movably sleeved on the outlet pipe 11 of the anti-surge valve and in close contact with the outer surface of the outlet pipe 11 of the anti-surge valve; the outer surfaces of the two quick-release buckles 3 are respectively threaded to the inner wall of the corresponding two second quick-release screw holes 25, and respectively extend through the corresponding two first quick-release screw holes 13 to the corresponding two third quick-release screw holes 26; the filter structure 6 includes a second flange 61, the right end of which is fixedly connected to a guide pipe 62, and the right end of the guide pipe 62 is fixedly connected to a downstream pipe.

The outer surfaces of several bolts 4 are threaded to the inner walls of the corresponding first fixing holes 27 and extend into the corresponding second fixing holes 64.

[0036] It should be noted that this utility model is a quick-release anti-surge valve connector assembly. During installation, pick up the main connector 1, align the inner tube 21 of the quick-release structure 2 with the anti-surge valve outlet pipe 11 of the main connector 1, so that the inner tube 21 is movably sleeved inside the anti-surge valve outlet pipe 11.

The fluid flows within the quick-release structure 2, passes through the first flange 23, and enters the guide pipe 62 of the filter structure 6. When the fluid flows within the guide pipe 62, it first passes through the spiral guide plate 66, forming a spiral flow under its guidance. Then, the fluid flows through the filter screen 67, which filters impurities in the fluid. The filtered fluid continues to flow within the guide pipe 62 and finally flows into the downstream pipeline through the downstream pipeline fixing flange 63. When disassembly is required, first disconnect the downstream pipe from the downstream pipe fixing flange 63 to separate the component from the downstream pipe. Unscrew several nuts 5 and remove several bolts 4 from the first fixing screw hole 27 and the second fixing screw hole 64. Separate the quick-release structure 2 and the filter structure 6. Rotate the two quick-release buckles 3 to remove them from the second quick-release screw hole 25, the first quick-release screw hole 13 and the third quick-release screw hole 26.
