Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to an electromagnetic fluorine-lined diaphragm valve. Background Technique

[0002] A diaphragm valve is a valve body that uses a diaphragm as a closing part to seal the flow channel, cut off the fluid, and separate the inner cavity of the valve body and the inner cavity of the valve cover. In order to achieve remote control, electromagnetic diaphragm valves are widely used in various fields. An electromagnetic diaphragm valve is a diaphragm that drives a sealing member to move through an electrical signal to change or switch the passage.

[0003] The existing electromagnetic fluorine-lined diaphragm valve includes a valve body and a valve cover. The valve cover is located at the upper end of the valve body. When the diaphragm inside the valve body needs to be maintained regularly, the valve cover needs to be disassembled. However, the existing valve cover is fixedly installed at the upper end of the valve body by multiple screws, which is not convenient for quickly disassembling the valve cover. Therefore, an electromagnetic fluorine-lined diaphragm valve needs to be designed. Content of the Utility Model

[0019] Referring to Figures 1-4 , an electromagnetic fluorine-lined diaphragm valve provided by the present utility model includes a valve body 1 and a valve cover 2. A mounting seat 3 is fixedly connected to the circumferential surface of the valve body 1. The mounting seat 3 is located at the upper end of the valve body 1. First connection components are arranged and connected at both the front and rear ends of the mounting seat 3. The valve cover 2 is located at the upper end of the mounting seat 3. The mounting seat 3 is connected to the valve cover 2 through the first connection components. A positioning shaft 9 is fixedly connected to the upper end of the mounting seat 3. A second jack 10 is provided on the circumferential surface of the positioning shaft 9. A positioning hole 11 is provided on the upper end surface of the valve cover 2. The positioning shaft 9 and the positioning hole 11 cooperate with each other. A second connection component is arranged and connected at the upper end of the valve cover 2. The second connection component passes through the second jack 10 and is connected to the positioning shaft 9.

[0020] During operation, with the mutual cooperation of the first connection component and the second connection component, the valve cover 2 can be conveniently and quickly disassembled.

[0021] Furthermore, the valve body 1 includes a protrusion, an electromagnetic coil, a static iron core, a second spring, a moving iron core, a valve rod, a valve flap, and a diaphragm. The electromagnetic coil is fixedly installed on the inner side wall of the valve cover 2. The static iron core is fixedly installed at the inner top of the valve cover 2 and is located inside the electromagnetic coil. The lower end of the static iron core is fixedly connected to the second spring. The end of the second spring away from the static iron core is fixedly connected to the moving iron core. The lower end of the moving iron core is fixedly connected to the valve rod. The lower end of the valve rod is fixedly connected to the valve flap. A diaphragm and a protrusion are fixedly connected inside the valve body 1. The diaphragm is located directly above the protrusion. The valve flap and the diaphragm cooperate with each other. The inner wall of the valve body 1 and the outer surface of the protrusion are both coated with a fluorine lining layer. The diaphragm and the protrusion cooperate with each other to form the conduction or closing of the valve body 1.

[0022] During operation, when the electromagnetic coil is energized, under the action of the electromagnetic coil, the moving iron core can move upward, thereby driving the valve rod and the valve flap to move upward. At the same time, the second spring is compressed. As the valve flap moves upward, the moving iron core and the static iron core are adsorbed to each other. At this time, the diaphragm is no longer squeezed. At this time, the liquid can flow through the valve body 1 from left to right. When the power is turned off and the electromagnetic coil is de-energized, the valve flap moves downward under the action of the second spring and its own gravity until the valve flap tightly squeezes the diaphragm and cooperates with the protrusion. At this time, a semi-closed space is formed inside the valve body 1, and the liquid can no longer pass through the valve body 1. Since the inner wall of the valve body 1 and the outer surface of the protrusion are both coated with a fluorine lining layer, the corrosion resistance of the valve body 1 and the protrusion can be increased.

[0023] Further, the first connection component includes a pressing plate 6, a fixed seat 5, a fixed rod 4, a U-shaped groove 8 and a first jack 7. Fixed seats 5 are fixedly connected to both the front and rear ends of the mounting seat 3. A fixed rod 4 is fixedly connected inside the fixed seat 5. The circumferential surface of the fixed rod 4 is rotatably connected to the pressing plate 6. A U-shaped groove 8 is formed on the upper end surface of the pressing plate 6, and a first jack 7 is formed on the left end surface of the pressing plate 6. The second connection component passes through the second jack 10 to be connected to the first connection component.

[0024] During operation, when it is necessary to disassemble the valve cover 2, first move the second connection component away from the pressing plate 6 and the positioning shaft 9, and then the pressing plate 6 can be rotated in the direction away from the valve cover 2 so that the pressing plate 6 no longer tightly presses the valve cover 2, and at this time, the valve cover 2 can be disassembled.

[0025] Further, the second connection component includes a handle 12, a support plate 13, a first spring 15, a plug rod 16 and a sliding seat 14. A support plate 13 is fixedly connected to the upper end of the mounting seat 3. A plug rod 16 is slidably connected inside the support plate 13. A handle 12 is fixedly connected to the end of the plug rod 16 away from the positioning shaft 9. A sliding seat 14 is fixedly connected to the circumferential surface of the plug rod 16. The sliding seat 14 is slidably connected to the valve cover 2. A first spring 15 is arranged between the sliding seat 14 and the support plate 13. One end of the first spring 15 is fixedly connected to the support plate 13, and the other end of the first spring 15 is fixedly connected to the sliding seat 14.

[0026] During operation, when disassembling the valve cover 2, it is necessary to first pull the handle 12 to drive the plug rod 16 to move in the direction away from the positioning shaft 9 until the plug rod 16 completely moves away from the pressing plate 6 and the positioning shaft 9, and then the first connection component can be controlled, and then the valve cover 2 can be disassembled.

[0027] Further, the diameter of the plug rod 16 matches the diameters of the second jack 10 and the first jack 7, and the plug rod 16 is slidably connected to the second jack 10 and the first jack 7.

[0028] During operation, this enables the plug rod 16 to smoothly pass through the second jack 10 and the first jack 7 to be connected to the pressing plate 6 and the positioning shaft 9.

[0029] Further, the width of the U-shaped groove 8 is greater than the diameter of the positioning shaft 9.

[0030] During operation, when rotating the pressing plate 6, under the action of the U-shaped groove 8, the pressing plate 6 can smoothly pass through the positioning shaft 9 and press on the upper end of the valve cover 2.

[0031] Working principle:

[0032] In use, when it is necessary to disassemble the valve cover 2, first pull the handle 12 to drive the insertion rod 16 and the sliding seat 14 to move away from the positioning shaft 9, and at the same time compress the first spring 15 until the insertion rod 16 completely moves away from the pressure plate 6 and the positioning shaft 9. Then, the pressure plate 6 can be rotated along the fixed rod 4 to make the pressure plate 6 move away from the valve cover 2. At this time, the valve cover 2 can be disassembled from the upper end of the mounting seat 3, so as to facilitate the maintenance of the parts inside the valve body 1. When it is necessary to install the valve cover 2, pick up the valve cover 2 so that the positioning hole 11 on the valve cover 2 moves along the positioning shaft 9 and presses on the upper end of the mounting seat 3. Then rotate the pressure plate 6 to make the pressure plate 6 press on the upper end of the valve cover 2. At this time, the positioning shaft 9 is located inside the U-shaped groove 8, and at the same time the first jack 7 is aligned with the second jack 10. Then release the handle 12. Under the action of the first spring 15, the insertion rod 16 moves towards the pressure plate 6 until the insertion rod 16 passes through the second jack 10 and the first jack 7. At this time, the insertion rod 16 is successfully connected to the positioning shaft 9 and the pressure plate 6, thus realizing the installation of the valve cover 2.
