Description

Technical Field

[0001] This utility model relates to the field of pressure regulating valve technology, specifically a pressure regulating valve with a quick-installation structure. Background Technology

[0002] Pressure regulating valves are key devices used for automatic pressure control in fluid systems. They are widely used in industrial automation, petrochemicals, power energy, water treatment, pharmaceuticals, food processing, and other fields. Their core function is to stabilize the system pressure within a set range by dynamically balancing the pressure difference between the inlet and outlet ends, thereby ensuring the safety and stability of the process.

[0003] Traditional flange butt installation typically involves passing multiple independent bolts through corresponding holes on the two flanges and tightening them manually one by one. However, it is difficult to ensure the order of force application and the consistency of torque when manually tightening bolts in different positions. This can easily lead to local stress concentration or excessive gaps between the flanges. Especially under large-diameter and high-pressure conditions, even a small angular deviation can cause leakage risks at the sealing surface. Furthermore, multiple adjustments are time-consuming and labor-intensive, resulting in low installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure regulating valve with a quick-installation structure, which solves the problem of traditional flange butt installation, which usually involves multiple independent bolts passing through corresponding holes on two flanges and tightening nuts one by one manually. Since it is difficult to ensure the order of force application and the consistency of torque when manually tightening bolts at different positions, it is easy to cause local stress concentration or excessive gap between flanges. Especially under large-diameter and high-pressure conditions, even a small angular deviation can cause leakage risk at the sealing surface. Moreover, multiple adjustments are time-consuming and laborious, resulting in low installation efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a pressure regulating valve with a quick-installation structure, comprising a pressure regulating valve, both ends of which are fixedly mounted with flanges, and the outer surface of each flange is fixedly mounted with a positioning mechanism, the positioning end of which is located on one side of the flange.

[0006] Furthermore, the positioning mechanism includes a fixing ring, which is fixedly installed on the outer surface of the flange. A slide rod is slidably connected inside the fixing ring. The number of slide rods is fixed to two. A fixing plate is fixedly installed at one end of each slide rod. An arc-shaped connecting plate is fixedly installed between the two fixing plates.

[0007] Furthermore, a bolt is threaded into the inner center of the arc-shaped connecting plate, one end of the bolt is rotatably connected to the inside of the fixing ring, and a throttle handle is fixedly installed on one end of the bolt.

[0008] Furthermore, a positioning plate is fixedly installed at the end of the slide rod away from the fixed plate, and the positioning plate is located on one side of the flange.

[0009] Furthermore, a pressure block is fixedly installed on one side of each positioning plate.

[0010] Furthermore, anti-slip stripes are provided on one side of the pressure block.

[0011] This utility model has the following beneficial effects: (1) In this utility model, the external connecting flange is inserted from one side of the flange into the space between the flange and the positioning plate. After the position is aligned, the handle is turned, and the handle drives the bolt to rotate inside the fixing ring. Since the bolt and the arc-shaped connecting plate are internally threaded, when the bolt rotates, the arc-shaped connecting plate will drive the two sliding rods to slide inside the fixing ring through the fixing plate. The movement of the sliding rods drives the positioning plate and the pressure block to move. The movement of the pressure block fixes and limits the external connecting flange. Then the flange and the external connecting flange can be connected. This avoids the flange offset problem caused by uneven force when tightening multiple bolts one by one in the traditional flange. Frequent manual calibration is not required, which greatly improves the assembly efficiency and ease of operation.

[0012] (2) When the pressure block presses the external connecting flange, the anti-slip stripe will release from the external connecting flange, increasing the friction of the contact, avoiding the slippage when limiting the external connecting flange, and improving the stability of the limit.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 As shown, this utility model is a pressure regulating valve with a quick installation structure, including a pressure regulating valve 1, with flanges 2 fixedly installed at both ends of the pressure regulating valve 1, and positioning mechanisms 3 fixedly installed on the outer surface of the flanges 2, with the positioning end of the positioning mechanism 3 located on one side of the flange 2.

[0018] The positioning mechanism 3 includes a fixing ring 301, which is fixedly installed on the outer surface of the flange 2. A slide rod 302 is slidably connected inside the fixing ring 301. The number of slide rods 302 is fixed to two. A fixing plate 303 is fixedly installed at one end of each slide rod 302. An arc-shaped connecting plate 304 is fixedly installed between the two fixing plates 303. The inner center of the arc-shaped connecting plate 304 is threaded with a bolt 305. One end of the bolt 305 is rotatably connected to the inside of the fixing ring 301. A handle 306 is fixedly installed on one end of the bolt 305. A positioning plate 307 is fixedly installed at the end of the slide bar 302 away from the fixed plate 303, and the positioning plate 307 is located on one side of the flange 2; A pressure block 308 is fixedly installed on one side of the positioning plate 307; Insert the external connecting flange from one side of the flange 2 between the flange 2 and the positioning plate 307. Once aligned, turn the handle 306. The handle 306 will cause the bolt 305 to rotate inside the fixing ring 301. Since the bolt 305 and the arc-shaped connecting plate 304 are internally threaded, when the bolt 305 rotates, the arc-shaped connecting plate 304 will drive the two sliding rods 302 to slide inside the fixing ring 301 through the fixing plate 303. The movement of the sliding rods 302 will drive the positioning plate 307 and the pressure block 308 to move. The movement of the pressure block 308 will fix and limit the external connecting flange. Then, the flange 2 and the external connecting flange can be connected. This avoids the flange offset problem caused by uneven force when tightening multiple bolts one by one in traditional flanges. Frequent manual calibration is not required, which greatly improves assembly efficiency and ease of operation.

[0019] Anti-slip stripes 309 are provided on one side of the pressure block 308; While the pressure block 308 presses against the external connecting flange, the anti-slip stripe 309 will disengage from the external connecting flange, increasing the friction of the contact and preventing slippage when limiting the external connecting flange, thus improving the stability of the limit.

[0020] In use, first insert the external connecting flange from one side of the flange 2 between the flange 2 and the positioning plate 307. After the position is aligned, turn the handle 306. The handle 306 drives the bolt 305 to rotate inside the fixing ring 301. Since the bolt 305 and the arc-shaped connecting plate 304 are internally threaded, when the bolt 305 rotates, the arc-shaped connecting plate 304 will drive the two sliding rods 302 to slide inside the fixing ring 301 through the fixing plate 303. The movement of the sliding rods 302 drives the positioning plate 307 and the pressure block 308 to move. The movement of the pressure block 308 fixes and limits the external connecting flange. Then, the connection between the flange 2 and the external connecting flange can be made. This avoids the flange offset problem caused by uneven force when tightening multiple bolts one by one in the traditional flange. It eliminates the need for frequent manual calibration and greatly improves assembly efficiency and ease of operation. While the pressure block 308 presses against the external connecting flange, the anti-slip stripe 309 will disengage from the external connecting flange, increasing the friction of the contact and preventing slippage when limiting the external connecting flange, thus improving the stability of the limit.
