Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to a corrosion-resistant fitting. Background Technology

[0002] The petrochemical industry regularly transports various highly corrosive chemical raw materials, such as solutions containing sulfuric acid, hydrochloric acid, and sodium hydroxide. Traditional metal joints, such as those made of ordinary carbon steel, are prone to chemical reactions when in contact with these corrosive media, causing rapid rusting and corrosion. This not only reduces the strength of the joint itself and increases the risk of leakage, but also may contaminate chemical products by mixing corrosion products into the transported fluid, leading to substandard production batches and huge economic losses. Existing corrosion-resistant pipe joints can basically meet daily usage needs, but there are still some shortcomings that need to be improved.

[0003] The corrosion-resistant pipe fittings widely used in the market typically employ a high-strength alloy coating inside to enhance the internal corrosion resistance. These pipe fittings connect to multiple external pipes via distribution pipes for material feeding. Most of the connectors on these external pipes are fixed to the connectors on the distribution pipes using threads. However, in actual use, since the connectors and distribution pipes are located externally, once the connection point between the connector and the distribution pipe comes into contact with external moisture, it is prone to corrosion. This not only affects the sealing performance of the connection between the connector and the distribution pipe but also increases the difficulty of subsequent maintenance of the pipe connection. Therefore, we propose a corrosion-resistant fitting to solve the above problems. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a corrosion-resistant connector to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A corrosion-resistant connector includes a connector body, shunt pipes installed on both sides of the connector body, and multiple sets of connecting connectors connected to the shunt pipes. A sealing base plate is installed at the lower end of one shunt pipe, and a sealing top plate is installed at the upper end of the other shunt pipe. Two sets of guide posts are installed at the top of each of the two sets of shunt pipes. A screw is rotatably connected between the two sets of shunt pipes. A connecting plate is installed on the outside of the screw. The middle of the connecting plate is threadedly connected to the screw through a threaded sleeve. Connecting plates are installed on both sides of the connecting plate. Guide holes corresponding to the guide posts are opened on both sets of connecting plates. The guide posts pass through the guide holes. Insert plates are installed at the top of each of the two sets of sealing top plates. Two sets of insertion holes are opened on each of the two sets of connecting plates. Both sets of insertion plates can pass through the insertion holes. Movable positioning components are installed on each of the connecting plates.

[0008] As an improved technical solution, the movable positioning component includes a sliding sleeve installed between two sets of insertion holes on a connecting plate, a sliding rod fixed inside the sliding sleeve, and two sets of movable blocks disposed outside the sliding rod. A locking rod is fixed at one end of each set of movable blocks opposite to each other, and a push handle is installed at the end of each set of movable blocks away from the connecting plate. A return spring is wound around the outside of the sliding rod, and a locking hole is opened at the upper end of each insertion plate. The end of the locking rod can be inserted into the locking hole in the insertion plate.

[0009] As an improved technical solution, both the sealing base plate and the sealing top plate are provided with arc-shaped grooves corresponding to the number of connecting joints, and sealing gaskets are glued inside the grooves.

[0010] As an improved technical solution, each of the two sets of movable blocks inside the sliding sleeve is provided with a sliding hole corresponding to the sliding rod, and the two sets of movable blocks are slidably connected to the sliding rod through the sliding hole.

[0011] As an improved technical solution, the two ends of the return spring are respectively connected to the outer wall of one end of the two sets of movable blocks, and the two sets of movable blocks are elastically connected to each other through the return spring.

[0012] As an improved technical solution, the outer wall of the locking rod is fully fitted with the inside of the lock hole on the insert plate.

[0013] As an improved technical solution, the edges of the push handle are all rounded, and anti-slip textures are provided on the outer surface of the push handle.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] I. This utility model features a sealing bottom plate and a liftable sealing top plate at the upper and lower ends of the diversion pipe on the main body of the connector. A rotatable screw allows the connecting plate to drive two sets of connecting plates to descend vertically. The two sets of sealing top plates can then move above the sealing bottom plate under the influence of the two sets of connecting plates. This allows the sealing top plate and sealing bottom plate to form a seal at the connection between the multiple sets of connecting connectors and the diversion pipe, effectively preventing the connection between the connecting connectors and the diversion pipe from contacting external moisture and causing corrosion. This effectively improves the corrosion resistance of the device and ensures that the equipment can be used normally for a long time.

[0016] II. This utility model has a sliding sleeve installed on the connecting plate, and two sets of movable blocks installed inside the sliding sleeve. The push handles at the front ends of the two sets of movable blocks can be pushed in opposite directions, causing the two sets of movable blocks to move in opposite directions, so that the two sets of locking rods completely leave the lock holes on the insert plate, thereby detaching the connection between the insert plate and the connecting plate. Then, the sealing top plate can be pulled down, allowing the two sets of insert plates on the sealing top plate to leave the two sets of insert holes on the connecting plate. This allows for quick disassembly of the entire sealing top plate, facilitating the rapid replacement of the sealing gasket on the sealing top plate. Attached Figure Description

[0028] Figures 1 to 5As shown, this embodiment provides a corrosion-resistant connector, including a connector body 1, diversion pipes 2 installed on both sides of the connector body 1, and multiple sets of connecting connectors 3 connected to the diversion pipes 2. A sealing base plate 4 is installed at the lower end of one diversion pipe 2, and a sealing top plate 5 is installed at the upper end of the other diversion pipe 2. Two sets of guide posts 6 are installed at the top of both diversion pipes 2. A screw 7 is rotatably connected between the two diversion pipes 2. A connecting plate 8 is installed on the outside of the screw 7. The middle part of the connecting plate 8 is threadedly connected to the screw 7 through a threaded sleeve 9. Connecting plates 10 are installed on both sides of the connecting plate 8. Guide holes 11 corresponding to the guide posts 6 are opened on both sets of connecting plates 10. The guide posts 6 pass through the guide holes 11. Insert plates 12 are installed at the top of both sets of sealing top plates 5. Two sets of insertion holes 13 are opened on both sets of connecting plates 10. Both sets of insertion plates 12 can pass through the insertion holes 13. Movable positioning components are installed on both sets of connecting plates 10.

[0029] By setting a sealing base plate 4 and a liftable sealing top plate 5 at the upper and lower ends of the diversion pipe 2 on the main body 1 of the connector, the screw 7 can be rotated to allow the connecting plate 8 to drive the two sets of connecting plates 10 to descend vertically. The two sets of sealing top plates 5 can be moved above the sealing base plate 4 under the action of the two sets of connecting plates 10. The sealing top plate 5 and the sealing base plate 4 can form a seal between the connection joints 3 and the diversion pipe 2, thereby effectively preventing the connection joints 3 and the diversion pipe 2 from contacting external moisture and causing corrosion at the connection. This effectively improves the corrosion resistance of the device and ensures that the equipment can be used normally for a long time.

[0030] In other embodiments, the movable positioning assembly includes a sliding sleeve 15 installed between two sets of insertion holes 13 on the connecting plate 10, a sliding rod 16 fixed inside the sliding sleeve 15, and two sets of movable blocks 17 disposed outside the sliding rod 16. A locking rod 18 is fixed to one end of each set of movable blocks 17 opposite to the connecting plate 10. A push handle 19 is installed at one end of each set of movable blocks 17 away from the connecting plate 10. A return spring 20 is wound around the outside of the sliding rod 16. A locking hole 21 is opened at the upper end of the insertion plate 12. The end of the locking rod 18 can be inserted into the locking hole 21 on the insertion plate 12.

[0031] By installing a sliding sleeve 15 on the connecting plate 10, and installing two sets of movable blocks 17 inside the sliding sleeve 15, when it is necessary to replace or maintain the sealing gasket 14 on the sealing top plate 5, the push handles 19 at the front ends of the two sets of movable blocks 17 can be pushed in opposite directions, so that the two sets of movable blocks 17 drive the two sets of locking rods 18 to move in opposite directions, so that the two sets of locking rods 18 completely leave the inside of the locking hole 21 on the insert plate 12, thereby disconnecting the connection between the insert plate 12 and the connecting plate 10. Then the sealing top plate 5 can be pulled down, so that the two sets of insert plates 12 on the sealing top plate 5 leave the inside of the two sets of insertion holes 13 on the connecting plate 10, thereby quickly disassembling the entire sealing top plate 5, which facilitates the quick replacement of the sealing gasket 14 on the sealing top plate 5.

[0032] like Figure 4 As shown, both the sealing base plate 4 and the sealing top plate 5 have arc-shaped grooves corresponding to the number of connecting joints 3, and sealing gaskets 14 are glued inside the grooves.

[0033] With this design, when the sealing top plate 5 moves to the top of the sealing bottom plate 4, the sealing bottom plate 4 and the sealing top plate 5 can completely surround the multiple sets of connecting joints 3 on the diversion pipe 2, and the sealing gasket 14 can effectively seal the connection between the connecting joint 3 and the diversion pipe 2, effectively preventing the connection between the diversion pipe 2 and the connecting joint 3 from being corroded by the outside.

[0034] like Figure 5 As shown, the two sets of movable blocks 17 inside the sliding sleeve 15 are each provided with sliding holes corresponding to the sliding rod 16, and the two sets of movable blocks 17 are slidably connected to the sliding rod 16 through the sliding holes;

[0035] This design ensures that when the push handle 19 at the front end of the movable block 17 is pushed laterally, the movable block 17 can slide smoothly along the slide bar 16, allowing the movable block 17 to drive the locking bar 18 to smoothly leave or enter the lock hole 21 on the insert plate 12.

[0036] like Figure 5 As shown, the two ends of the return spring 20 are respectively connected to the outer wall of one end of the two sets of movable blocks 17, and the two sets of movable blocks 17 are elastically connected to each other through the return spring 20.

[0037] This design allows the return spring 20 to apply opposing elastic forces to the two sets of movable blocks 17 outside the slide bar 16, enabling the two sets of movable blocks 17 to drive the two sets of locking rods 18 to move quickly to both sides, allowing the two sets of locking rods 18 to be quickly inserted into the lock holes 21 on the insert plate 12.

[0038] like Figure 5 As shown, the outer wall of the locking rod 18 fits perfectly with the inside of the lock hole 21 on the insert plate 12;

[0039] With this design, when the locking rod 18 on the movable block 17 can be inserted into the locking hole 21 on the insert plate 12, the locking rod 18 can form a stable movement limit on the insert plate 12, preventing the insert plate 12 from becoming loose during use.

[0040] like Figure 4 As shown, the edges of the push handle 19 are all rounded, and anti-slip textures are provided on the outer surface of the push handle 19.

[0041] This design effectively increases the friction between the push handle 19 and the user's hand, thereby facilitating the lateral movement of the movable block 17.

[0042] This utility model provides a corrosion-resistant connector, the specific working principle of which is as follows:

[0043] When using this equipment, first rotate the screw 7 so that the threaded sleeve 9 on the connecting plate 8 can drive the two sets of connecting plates 10 to rise vertically upward along the guide column 6 under the action of the thread, and allow the two sets of sealing top plates 5 to rise vertically under the action of the connecting plates 10, so that the sealing top plates 5 and the sealing bottom plates 4 are separated. Then, the connecting joint 3 can be installed on the diversion pipe 2. After the connecting joint 3 is installed, rotate the screw 7 in the opposite direction so that the connecting plate 8 can drive the two sets of connecting plates 10 to fall vertically, and allow the two sets of sealing top plates 5 to move above the sealing bottom plates 4 under the action of the two sets of connecting plates 10. This allows the sealing top plates 5 and the sealing bottom plates 4 to form a seal between the multiple sets of connecting joints 3 and the diversion pipe 2, thereby effectively preventing the connection between the connecting joints 3 and the diversion pipe 2 from contacting external moisture and causing corrosion at the connection. The operation is then complete.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
