Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, in particular to an anti-corrosion electromagnetic valve which is convenient to disassemble and assemble. Background Art

[0002] Anti-corrosion solenoid valve refers to a valve device that is suitable for various strong acid and alkali gases and liquids as working media, and is widely used in automatic control systems such as medical and pharmaceutical, chemical, environmental protection or cleaning equipment to open and close the medium pipeline.

[0003] In order to facilitate the disassembly and assembly of the anti-corrosion solenoid valve, the prior art has made many improvements to the anti-corrosion solenoid valve, such as the patent with the patent publication number CN218780823U, which discloses an anti-corrosion solenoid valve that is easy to disassemble and assemble, including a solenoid valve body, one end of the solenoid valve body is provided with a connector, and the outer wall of the connector is connected with a movable sleeve, and one end of the movable sleeve is fixed with a slider. The utility model is fitted with the solenoid valve body through the connector, and is threadedly connected with the connector through the movable sleeve, which is convenient for fixing the connector so that the medium pipeline is connected with the solenoid valve body. When disassembly is required, the movable sleeve is loosened, and the slider welded to the movable sleeve slides along the slide groove on the receiving sleeve, and when the movable sleeve is twisted, the receiving sleeve is pushed to move to the pneumatic structure of the solenoid valve body. A damping spring is installed between the receiving sleeve and the pneumatic structure to prevent the movable sleeve from detaching from the solenoid valve body. At the same time, when the solenoid valve body and the connector are disconnected, the elastic support of the damping spring is used to make the receiving sleeve push the movable sleeve to cover the connector to avoid shaking.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] The above-mentioned comparative document is threadedly connected to the connecting piece through a movable sleeve, which is convenient for fixing the connecting piece. In reality, the anti-corrosion solenoid valve is composed of an upper shell, a lower shell and a valve body installed on the upper shell. In the prior art, the upper shell and the lower shell are connected and fixed by multiple mounting bolts (the prior art basically has four mounting bolts). Therefore, when it is necessary to inspect the inside of the anti-corrosion solenoid valve, it is necessary to remove several mounting bolts, and several bolts need to be installed after maintenance, which makes it inconvenient for maintenance personnel to disassemble and assemble the upper shell and the lower shell of the anti-corrosion solenoid valve. Therefore, this field is in urgent need of improving the anti-corrosion solenoid valve that is easy to disassemble and assemble, so as to solve the defects of the prior art. Utility Model Content

[0008] Preferably, the lower end of each connecting plate is fixedly connected to a moving frame adapted to the moving groove and in an L shape, and a spring is provided between the lower portion of the wedge block and one side of the moving frame.

[0009] Preferably, a polygonal limiting block is fixedly connected to one side of each of the fixing plates, and a limiting groove adapted to the limiting block is formed on the top wall of the adjusting groove.

[0010] Preferably, a first magnet is embedded on one side of each of the limiting blocks, and a second magnet matching the first magnet is embedded on the top wall of each of the limiting grooves.

The lower shell and the upper shell are quickly sealed and installed or disassembled through the cooperation of the wedge block and the extrusion bevel, which is convenient for disassembly and assembly of the anti-corrosion solenoid valve body.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1

[0029] See also Figure 1-Figure 6 A corrosion-resistant solenoid valve that is easy to disassemble and assemble comprises an corrosion-resistant solenoid valve body, the corrosion-resistant solenoid valve body comprises a lower shell 1, an upper shell 2 and a valve body 3 installed on the upper part of the upper shell 2, a symmetrical adjusting groove 4 is provided on one side of the upper shell 2 facing the lower shell 1, a fixing plate 5 is provided at both ends of each adjusting groove 4, a bidirectional screw rod 6 is rotatably connected between the two fixing plates 5, two symmetrical moving blocks 7 that are threadedly connected to the bidirectional screw rod 6 are slidably connected in the adjusting groove 4, a symmetrical moving groove 8 that is adapted to the adjusting groove 4 is provided on the upper part of the lower shell 1, a clearance opening 9 that is adapted to the two moving blocks 7 is provided through the inner side wall of the moving groove 8, and a connecting plate 1 is fixedly connected to the lower side of the moving block 7 0, a displacement port 12 adapted to the connecting plate 10 is provided on one side of the lower shell 1 facing the upper shell 2, and the displacement port 12 is communicated with the moving groove 8, and a wedge block 11 adapted to the moving groove 8 is provided on the side of each connecting plate 10, and a symmetrical extrusion bevel 13 adapted to the wedge block 11 is provided on the inner top wall of the moving groove 8, and the two-way screw rod 6 drives the two moving blocks 7 to move toward or away from each other when rotating, one end of the two-way screw rod 6 extends to the outside and is fixedly connected with a rotating block 14, and a side surface of one end of the two-way screw rod 6 extending to the outside is threadedly connected to a limiting nut 15, and a positioning groove 23 is provided on the facing surfaces of the upper shell 2 and the lower shell 1, and a sealing ring 24 is embedded in the positioning groove 23.

[0030] Specific implementation method in this embodiment: the above-mentioned anti-corrosion solenoid valve body structure is the same as the anti-corrosion solenoid valve structure and working principle in the prior art. For example, the patent with patent publication number CN218780823U discloses an anti-corrosion solenoid valve that is easy to disassemble and assemble. The utility model mainly improves the installation method between the lower shell 1 and the upper shell 2, which is convenient for disassembling and assembling the lower shell 1 and the upper shell 2 of the anti-corrosion solenoid valve body while improving the sealing effect of the two after installation. In this embodiment, when it is necessary to install between the lower shell 1 and the upper shell 2, the sealing ring 24 is clamped in the positioning groove 23, and the two rotating blocks 14 are rotated in turn to drive the corresponding two-way screw rod 6 to rotate. When a two-way screw rod 6 rotates, it drives the two moving blocks 7 to slide toward each other in the adjusting groove 4, so that the two moving blocks 7 are in the position of the give way port 9. Adaptation, by adapting the position of the moving block 7 and the yielding port 9, the upper shell 2 and the lower shell 1 are attached to each other on their facing surfaces, and the two moving blocks 7 are driven to move oppositely by the reverse rotation of the two-way screw 6 again. At this time, the connecting plate 10 moves in the displacement port 12, and the wedge block 11 moves along the corresponding extrusion bevel 13. Through the cooperation and extrusion of the wedge block 11 and the extrusion bevel 13, the upper shell 2 and the lower shell 1 are approached to each other, and then the sealing ring 24 is squeezed, the two-way screw 6 is tightened, and the limit nut 15 is tightened, so as to seal the lower shell 1 and the upper shell 2. At the same time, there is no need to install the upper shell 2 and the lower shell 1 through multiple mounting bolts (in actual situations, four mounting bolts are used for installation), which is convenient for disassembly and assembly of the anti-corrosion solenoid valve body. At the same time, the upper shell 2 and the lower shell 1 have a stable sealing effect after installation.

[0031] Embodiment 2

[0032] See also Figure 6 This embodiment includes the above-mentioned embodiment, wherein it further includes: the lower end of each connecting plate 10 is fixedly connected to a moving frame 16 that is adapted to the moving groove 8 and is L-shaped, a spring 17 is provided between the lower part of the wedge block 11 and one side of the moving frame 16, a guide column 22 is fixedly connected to the lower side of the wedge block 11, the spring 17 is sleeved on the side of the guide column 22, and the cross-section of the guide column 22 is a polygon.

[0033] Specific implementation method in this embodiment: In this embodiment, when the moving block 7 moves, the wedge block 11 is squeezed downward by the squeezing bevel 13. At this time, the spring 17 is compressed. The larger the distance between the two moving blocks 7, the greater the compression force on the spring 17. Conversely, the greater the force with which the wedge block 11 squeezes the lower shell 1, and thus the higher the sealing between the upper shell 2 and the lower shell 1. By setting the spring 17, it is also possible to prevent vibration when the anti-corrosion solenoid valve body is working, which may cause the wedge block 11 to loosen. At the same time, the guide column 22 prevents the spring 17 from producing a large deformation. The cross-section of the guide column 22 is a rectangular or other polygonal shape, which limits the position of the wedge block 11 and improves the sealing and stability of the upper shell 2 and the lower shell 1 after installation.

[0034] Implementation Three

[0035] See also Figure 3 and Figure 4 This embodiment includes all the above embodiments, and further includes: a polygonal limit block 18 is fixedly connected to one side of each fixing plate 5, a limit slot 19 adapted to the limit block 18 is opened on the top wall of the adjustment slot 4, a first magnet 20 is embedded on one side of each limit block 18, and a second magnet 21 adapted to the first magnet 20 is embedded on the top wall of each limit slot 19.

[0036] Specific implementation method in this embodiment: by setting the limit block 18 and the limit groove 19, when the upper shell 2 and the lower shell 1 are produced, it is only necessary to make grooves on the upper shell 2 and the lower shell 1. When the upper shell 2 and the lower shell 1 need to be installed, the fixed plate 5 is clamped in the limit groove 19 through the limit block 18, and is adsorbed and fixed by the first magnet 20 and the second magnet 21. The fixed plate 5, the bidirectional screw rod 6 and the movable block 7 can be reused, which improves the applicability of the overall device and reduces the cost of installing the anti-corrosion solenoid valve body.
