Description

Technical Field

[0001] The utility model relates to the technical field of screw valves, in particular to a concentric screw valve which is easy to clean. Background Art

[0002] The screw valve is a valve with a simple structure, good sealing performance, and high temperature and pressure resistance. Its working principle is to control the flow of the medium through the rotation of the screw. Due to its good sealing performance and flow regulation characteristics, it has been widely used in many fields. It has good corrosion resistance, sealing performance, is not easy to breed bacteria, and is easy to operate. During use, the screw valve needs to be cleaned regularly. When removing the screw from the sleeve, it needs to be rotated several times, which is troublesome. If the screw sleeve is accidentally deflected during rotation, it will cause damage to the parts and cause economic losses.

[0003] After searching, the Chinese patent publication number CN208221753U discloses a disassembly structure of a screw valve, including a disassembly body arranged at the bottom end of the valve body, in which a sleeve part which can rotate along its axis and is sleeved on the outside of the screw is installed, and an openable and closable disassembly flap is formed on the disassembly body; when the disassembly flap is closed, the disassembly flap is located on the side of the sleeve part and fixes the sleeve part.

[0004] In view of the lack of a function to assist in removing the sleeve from the screw in the above-mentioned technology, the screw and the sleeve may be deflected and damaged due to force deflection when the screw is manually removed; therefore, a concentric screw valve that is easy to clean is proposed.

[0008] In some embodiments, one end of the anti-deflection rod is fixedly connected to a limiting boss, and an anti-dropping groove is provided on one side of the anti-deflection rod.

[0009] In some embodiments, the mounting platform is slidably connected to an anti-dropping plate inside, a spring 2 is fixedly connected to one end of the anti-dropping plate and the inside of the mounting platform, a fixing bolt is threadedly connected to one end of the mounting platform and the mounting sleeve, and one end of the fixing bolt is movably connected to the anti-dropping plate.

[0031] When in use, the mounting platform 8 is fixed in the mounting sleeve 2. When the motor 1 is working, the screw 11 is driven to cooperate with the sleeve 5 to rotate and extrude the glue. The clamping ring 1 3 and the clamping ring 2 4 can fix the sleeve 5 from the outside. The top of the clamping ring 1 3 and the clamping ring 2 4 is fixed to one side of the mounting platform 8 through the anti-deflection rod 20.

[0032] When cleaning is required, the screw 11 and the sleeve 5 need to be rotated for multiple turns to separate them. At this time, the motor 1 can be reversed and the mounting platform 8 and the clamping ring can be pulled in opposite directions to separate them. During the separation process, the anti-deflection rod 20 cooperates with the extension rod 17 to prevent the worker's hand from deflecting and causing the screw 11 and the sleeve 5 to collide and cause damage to the parts. The spring 18 can push the extension rod 17 outward.

[0033] In this embodiment, the connection assembly includes a coupling joint 16 and a motor joint 25, one end of the motor joint 25 is fixedly connected to the power output end of the motor 1, one end of the coupling joint 16 is fixedly connected to the screw 11, and one end of the coupling joint 16 is fixedly connected to the motor joint 25;

[0034] One end of the coupling joint 16 is provided with a cross slot for convenient docking with a boss at one end of the motor joint 25 to drive the screw rod 11 to rotate.

[0035] In this embodiment, one end of the anti-deflection rod 20 is fixedly connected to a limiting boss 21, and an anti-dropping groove 22 is opened on one side of the anti-deflection rod 20. The limiting bosses 21 at both ends of the clamping ring 1 3 and the clamping ring 2 4 are combined and inserted into the groove at one end of the extension rod 17. After the anti-deflection rod 20 moves out of the limiting groove 15, it can still have a limiting effect on the clamping ring 1 3 and the clamping ring 2 4.

[0036] In this embodiment, the mounting platform 8 is slidably connected with an anti-dropping card plate 23, and a spring 24 is fixedly connected to one end of the anti-dropping card plate 23 and the mounting platform 8.

[0037] After the fixing bolt 19 is screwed into the mounting platform 8 and the mounting sleeve 2, the mounting platform 8 and the mounting sleeve 2 can be fixed. Then, the fixing bolt 19 that continues to move inward can squeeze the anti-dropping clamping plate 23 and insert it into the limiting groove 15 on one side of the anti-deflection rod 20 to fix it, thereby preventing the clamping ring 1 3 and the clamping ring 2 4 from falling off during work.

[0038] In this embodiment, one end of the clamping ring 1 3 is rotatably connected to the clamping ring 2 4, one end of the clamping ring 1 3 and the clamping ring 2 4 is fixedly connected to a clamping plate 9, one end of the clamping plate 9 is fixedly connected to a magnet 10, and the magnet 10 can be inserted into the groove on one side of the clamping ring 1 3 and the clamping ring 2 4 to fix the clamping ring 1 3 and the clamping ring 2 4 to prevent the sleeve 5 from falling off.

[0039] In this embodiment, one end of the sleeve 5 is fixedly connected to a limit plate 6 and a connecting pipe 7. The limit plate 6 can prevent the sleeve 5 from rotating along with the screw 11, and the connecting pipe 7 can be connected to an external rubber barrel.

[0040] In this embodiment: when in use, the mounting platform 8 is fixed in the mounting sleeve 2, and when the motor 1 is working, the screw 11 is driven to cooperate with the sleeve 5 to rotate and extrude the glue, and the clamping ring 1 3 and the clamping ring 2 4 can fix the sleeve 5 from the outside, and the clamping ring 1 3 and the clamping ring 2 4 are fixed to one side of the mounting platform 8 through the anti-deflection rod 20;

[0041] When cleaning is required, the screw 11 and the sleeve 5 need to be rotated for multiple turns to separate them. At this time, the motor 1 can be reversed and the mounting platform 8 and the clamping ring can be pulled in opposite directions to separate them. During the separation process, the anti-deflection rod 20 cooperates with the extension rod 17 to prevent the workers' hands from deflecting and causing the screw 11 and the sleeve 5 to collide and cause damage to the parts. The spring 18 can push the extension rod 17 outwards.

[0042] One end of the coupling joint 16 has a cross slot for easy docking with the boss at one end of the motor joint 25 to drive the screw 11 to rotate;

[0043] The limiting bosses 21 at both ends of the clamping ring 1 3 and the clamping ring 2 4 are combined and inserted into the slot at one end of the extension rod 17, so that the clamping ring 1 3 and the clamping ring 2 4 can still play a limiting effect after the anti-deflection rod 20 moves out of the limiting slot 15;

[0044] After the fixing bolt 19 is screwed into the mounting platform 8 and the mounting sleeve 2, the mounting platform 8 and the mounting sleeve 2 can be fixed. Then, the fixing bolt 19 that continues to move inward can squeeze the anti-dropping clamping plate 23 and insert it into the limiting groove 15 on one side of the anti-deflection rod 20 to fix it, so as to prevent the clamping ring 1 3 and the clamping ring 2 4 from falling off during work;

[0045] The magnet 10 can be inserted into the slots on one side of the clamping ring 1 3 and the clamping ring 2 4 to fix the clamping ring 1 3 and the clamping ring 2 4 to prevent the sleeve 5 from falling off;

[0046] The limit plate 6 can prevent the sleeve 5 from rotating together with the screw rod 11, and the connecting pipe 7 can be connected to an external rubber barrel.
