[0002] A float valve is a valve that uses the principle of buoyancy to control the flow of fluid. It mainly consists of a float, a transmission mechanism, and a valve body. The transmission mechanism is connected between the float and the valve body. When the float rises, the transmission mechanism receives the power of the float and controls the valve body to close; when the float drops, the transmission mechanism receives the power of the float and controls the valve body to open, thereby realizing directional opening and closing of the valve body.

[0003] When the float valve is installed on the horizontal surface of the container, the float ball fixes the water level of the container, so that the user cannot adjust the water level of the container at will, which makes it inconvenient for the user to use the float valve.

When the control valve is opened, the control valve is opened

[0006] By adopting the above technical solution, when the float valve is used, the valve body is fixed on the horizontal surface of the container, the float drops due to its own gravity, the rotating assembly receives the power of the float through the adjusting connecting rod and drives the limit block to rotate in the direction away from the drainage channel, driving the closing assembly to slide along the inner wall of the drainage channel in the direction away from the plastic core, the tight effect between the closing assembly and the plastic core disappears, the valve body is opened, the water in the drainage channel is injected into the inner cavity of the container through the inner ring of the plastic core and the closing assembly, the liquid level in the container continues to rise, and the float is affected by the buoyancy of the liquid in the container. When rising, the rotating assembly receives the power of the float through the adjusting connecting rod and drives the limit block to rotate toward the direction of the drainage channel, driving the closing assembly to slide along the inner wall of the drainage channel toward the direction of the plastic core. The surface of the closing assembly presses against the surface of the plastic core and seals the inner ring of the plastic core, thereby closing the valve body and realizing directional opening and closing of the valve body. When the water level in the container needs to be adjusted, the float is driven to rotate on the adjusting connecting rod to the water level height, so that the user can arbitrarily adjust the water level in the container, thereby improving the user's convenience in using the float valve.

[0012] By adopting the above technical solution, the ends of multiple elastic strips are spaced apart on the surface of the adjusting connecting rod around the axis of the threaded hole. The elastic force of the elastic strip drives the connecting ring close to the adjusting screw, and the insert is embedded in the threaded groove of the adjusting screw. The outer peripheral surface of the insert is pressed against the inner wall of the threaded groove of the adjusting screw to form a limit. When the adjusting connecting rod needs to be replaced, the connecting block is driven to rotate on the inner circle of the connecting ring, driving the adjusting screw to rotate, so that the end of the adjusting screw is disengaged from the threaded hole 2 and the threaded hole 1 in turn. The user does not need to find tools to unscrew the adjusting screw, thereby realizing the rapid separation of the adjusting connecting rod and the rotating connecting rod 2.

[0013] Optionally, the adjusting link is connected to a positioning assembly, and the positioning assembly includes a positioning rack 1, a positioning rack 2 and a positioning gear, and the adjusting link is provided with a positioning cavity for sliding of the positioning rack 1 on the surface facing the rotating link 2, and the end face of the positioning rack 1 protruding from the adjusting link can abut against the second surface of the rotating link, and the surface of the adjusting link is provided with a detection cavity for sliding of the positioning rack 2, and the positioning cavity is connected to the detection cavity, and the positioning gear is rotatably connected to the inner wall of the positioning cavity, and the positioning rack 1 and the positioning rack 2 both mesh with the tooth surface of the positioning gear. When the end of the adjusting screw is threadedly tightened and fixed on the inner wall of the threaded hole 2, and the surface of the adjusting link is tightly against the second surface of the rotating link, the second surface of the rotating link abuts against the surface of the positioning rack 1 and drives the positioning rack 1 to slide in the direction close to the positioning cavity, and the positioning gear rotates, driving the positioning rack 2 to slide in the direction close to the detection cavity, and the second end face of the positioning rack is flush with the surface of the adjusting link.

[0014] By adopting the above technical solution, when the end of the adjusting screw passes through the threaded hole one and is screwed and fixed on the inner wall of the threaded hole two, the surface of the adjusting link is pressed against the surface of the rotating link two, and at the same time, the surface of the rotating link two abuts against the rod surface of the positioning rack one protruding from the adjusting link and drives the positioning rack one to slide toward the direction close to the positioning cavity. The positioning rack one and the positioning rack two are both engaged with the positioning gear, and the positioning gear rotates, driving the positioning rack two to slide toward the direction close to the detection cavity. The end faces of the positioning rack two are flush with the surface of the adjusting link, so that the staff can directly observe the installation status between the rotating link two and the adjusting link, thereby improving the user's convenience in using the float valve.

[0015] Optionally, the positioning assembly further includes a positioning ring capsule, the outer ring wall of the positioning ring capsule is coaxially connected to the inner wall of the threaded hole, the inner ring wall of the positioning ring capsule abuts the outer peripheral surface of the adjusting screw, and the inner cavity of the positioning ring capsule is connected to the detection cavity. When the positioning rack 2 slides toward the direction close to the detection cavity, the air in the detection cavity is pushed into the inner cavity of the positioning ring capsule, and the inner ring wall of the positioning ring capsule is pressurized and expanded and abuts the outer peripheral surface of the adjusting screw to form a limit.

The elastic member has an elastic force that drives the positioning rack to slide in a direction away from the positioning cavity, and the end portion of the positioning rack protrudes to adjust the tendency of the connecting rod surface.

[0018] By adopting the above technical solution, when the adjusting screw is loosened in the second threaded hole, the abutment effect between the adjusting connecting rod surface and the second rotating connecting rod surface disappears, a gap exists between the adjusting connecting rod and the second rotating connecting rod, and the abutment effect of the second rotating connecting rod on the second positioning rack disappears.

At the same time, the positioning gear rotates, driving the second positioning rack to slide in the direction away from the detection cavity, and the two ends of the positioning rack protrude from the rod surface of the adjusting connecting rod, thereby alerting the staff to tighten the adjusting screw in time.

[0020] By adopting the above technical solution, the inner wall of the fixed ring groove abuts against the inner ring wall of the connecting ring to form a limit, so that the rotating part is not easy to separate from the inner ring of the connecting ring when the inner ring of the connecting ring rotates, thereby improving the stability of the rotating part rotating in the inner ring of the connecting ring.

[0021] Optionally, a control component is connected between the connecting ring and the connecting block, the control component elastic member 2 and the rotating rod, the force-applying part surface is provided with a rotating cavity for the rotating rod to rotate, the connecting ring surface is provided with a fixing groove for the end of the rotating rod to be embedded, one end of the elastic member 2 in the elastic direction is connected to the rod surface of the rotating rod, and the other end of the elastic member 2 in the elastic direction is connected to the inner wall of the rotating cavity.

The user grasps the surface of the force-applying part and drives the rotating part to rotate, driving the end of the adjusting screw to pass through the threaded hole and tighten it to the second inner wall of the threaded hole, and the notch of the fixed groove faces the rotating rod. The force-applying part is released so that the pressure on the rotating rod disappears. The second elastic force of the elastic part drives the rotating rod to rotate in the direction close to the fixed groove, and the end of the rotating rod is embedded in the fixed groove. The end face of the rotating rod is pressed against the inner wall of the fixed groove to form a limit, so that the rotating part is not easily offset on the inner ring of the connecting ring, thereby realizing the directional limit of the rotating part on the inner ring wall of the connecting ring.

[0023] Optionally, the control component also includes a magnetic block, an electromagnet and an inductive switch, the magnetic block is connected to the surface of the rotating rod facing the fixed slot, the electromagnet is connected to the inner wall of the fixed slot facing the magnetic block, when the electromagnet is energized and has magnetism, the electromagnet and the magnetic block are attracted and fixed by opposite poles, the inductive switch is connected to the surface of the adjusting connecting rod facing the adjusting screw, the inductive switch is electrically connected to the electromagnet, when the end of the adjusting screw is threaded and fixed on the second inner wall of the threaded hole, the inductive switch abuts against the surface of the adjusting screw and is turned on, and the electromagnet is energized.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses an adjustable float valve. Figure 1 and Figure 2 The adjustable float valve includes a valve body 1, a plastic core 2, a transmission mechanism 3 and an adjusting component 4. One end of the valve body 1 is fixed to the horizontal surface of the container by a hexagonal cap, and the other end of the valve body 1 is provided with a drainage channel 11, which runs through both ends of the valve body 1. In the embodiment of the present application, the material of the plastic core 2 is polyformaldehyde, which has low cost, is not easy to produce scale, and is corrosion-resistant. The outer ring wall of the plastic core 2 is fixed to the inner wall of the drainage channel 11 by industrial glue, and the inner ring of the plastic core 2 is connected to the drainage channel 11. The transmission mechanism 3 is installed between the valve body 1 and the adjusting component 4. The adjusting component 4 moves with the rise and fall of the liquid level in the container. The transmission mechanism 3 receives the power of the adjusting component 4 and controls the on and off of the drainage channel 11 to realize the directional opening and closing of the valve body 1.

[0033] Reference Figure 1 and Figure 2The transmission mechanism 3 includes a rotating component 31, a closing component 32 and a limit block 33. The closing component 32 is connected to the inner wall of the drainage channel 11. The closing component 32 can press against the surface of the plastic core 2 to form a seal. The closing component 32 includes a gasket 321 and a copper core 322. In the embodiment of the present application, the material of the gasket 321 is nitrile rubber. The copper core 322 is slidably connected to the inner wall of the drainage channel 11. The sliding direction of the copper core 322 and the axis of the copper core 322 are parallel to each other. A drainage cavity 3221 is provided on the surface of the copper core 322 facing the plastic core 2. The drainage cavity 3221 runs through both ends of the axis of the copper core 322. A limiting cavity 3222 for accommodating the gasket 321 is provided on the surface of the drainage cavity 3221 facing the plastic core 2. The outer peripheral surface of the gasket 321 presses against the inner wall of the limiting cavity 3222 to form a limit.

[0034] Reference Figure 1 and Figure 2 When the copper core 322 slides along the inner wall of the drainage channel 11 toward the plastic core 2, the surface of the plastic core 2 and the inner wall of the limiting cavity 3222 press against the two sides of the gasket 321 to form a seal, thereby closing the valve body 1; when the copper core 322 slides along the inner wall of the drainage channel 11 toward the direction away from the plastic core 2, the surface of the gasket 321 separates from the surface of the plastic core 2, and the pressing effect of the surface of the plastic core 2 and the inner wall of the limiting cavity 3222 on the gasket 321 disappears. The fluid in the drainage channel 11 passes through the inner ring of the plastic core 2 and the limiting cavity 3222 in turn and is discharged from the drainage cavity 3221, thereby opening the valve body 1.

[0035] Reference Figure 1 and Figure 2 The rotating component 31 is connected to the surface of the valve body 1. The rotating component 31 can drive the copper core 322 to slide on the inner wall of the drainage channel 11. The rotating component 31 includes a rotating link 1 311, a rotating link 2 312 and a rotating link 313. The end of the rotating link 1 311 and the end of the rotating link 2 312 are rotatably connected to the surface of the valve body 1 through a cotter pin. The rotation axis of the rotating link 1 311 and the rotation axis of the rotating link 2 312 are parallel to each other, and the rotating link 1 311 and the rotating link 2 312 are located on both sides of the drainage channel 11. The two ends of the rotating link 313 are rotatably connected to the surface of the rotating link 1 311 and the surface of the rotating link 2 312 through a cotter pin. The rotation axis of the rotating link 313 and the rotation axis of the rotating link 1 311 are parallel to each other.

[0036] Reference Figure 1 and Figure 2When the second rotating link 312 rotates toward the valve body 1, the third rotating link 313 receives the power of the second rotating link 312 and drives the first rotating link 311 to rotate toward the direction of the drainage channel 11, driving the limit block 33 to abut the surface of the copper core 322 and drive the copper core 322 along the inner wall of the drainage channel 11. It slides in the direction closer to the plastic core 2; when the rotating link 2 312 rotates in the direction away from the valve body 1, the rotating link 313 receives the power of the rotating link 1 311 and drives the rotating link 1 311 to rotate in the direction away from the drainage channel 11, and the tightening effect of the limit block 33 on the copper core 322 disappears. The copper core 322 slides along the drainage channel 11 in the direction away from the plastic core 2 under the influence of its own gravity, thereby realizing directional control of the sliding of the copper core 322 on the inner wall of the drainage channel 11.

[0037] Reference Figure 2 and Figure 3 The adjusting component 4 is installed in the end of the rotating link 312 away from the valve body 1, and the adjusting component 4 can drive the rotating link 312 to rotate; the adjusting component 4 includes an adjusting link 41, an adjusting screw 42 and a floating ball 43. One end of the adjusting link 41 in the length direction is provided with a threaded hole 411 for the end of the adjusting screw 42 to pass through. The surface of the rotating link 312 away from the valve body 1 is provided with a threaded hole 3121 for the end of the adjusting screw 42 to pass through. The end of the adjusting screw 42 passes through the threaded hole 411 and is screwed and fixed on the inner wall of the threaded hole 3121 to realize the installation of the adjusting link 41 and the rotating link 312. The axis of the adjusting screw 42 and the rotation axis of the rotating link 312 are parallel to each other, and the adjusting link 41 rotates around the axis of the adjusting screw 42 on the surface of the rotating link 312.

[0038] Reference Figure 2 and Figure 3The end face of the adjusting connecting rod 41 away from the threaded hole 411 in the length direction is fixed on the surface of the float 43. When the water level in the container needs to be adjusted, the adjusting connecting rod 41 is driven to rotate around the axis of the adjusting screw 42, driving the float 43 to rotate around the adjusting screw 42, so that the height of the float 43 in the container cavity changes. When the float 43 is rotated to the required water storage height of the container, it stops, and the rotating connecting rod 2 312 rotates in the direction away from the valve body 1 under the influence of its own gravity, and the water in the drainage channel 11 passes through the plastic The inner ring of the plastic core 2 and the limiting cavity 3222 are discharged from the drainage cavity 3221, and the liquid level in the container continues to rise. When the surface of the float 43 abuts the fluid in the container, the float 43 rises due to the buoyancy of the fluid in the container, driving the rotating connecting rod 2 312 to rotate toward the valve body 1. The surface of the plastic core 2 and the inner wall of the limiting cavity 3222 clamp the two sides of the gasket 321 to form a seal, thereby closing the valve body 1 and enabling the user to arbitrarily adjust the water level in the container, thereby improving the user's convenience in using the float valve.

The end face of the force-applying portion 532 is fixed to one side of the axis direction of the rotating portion 531. A fixed ring groove 5311 is coaxially provided on the outer peripheral surface of the rotating portion 531 for the inner ring of the connecting ring 51 to be embedded. The inner wall of the fixed ring groove 5311 abuts against the inner ring wall of the connecting ring 51 to form a limit. The axis of the rotating portion 531 coincides with the axis of the connecting ring 51, and the rotating portion 531 rotates around its own axis on the inner ring of the connecting ring 51.

The insert 52 can be embedded in the thread groove of the adjusting screw 42, and the outer peripheral surface of the insert 52 is pressed against the inner wall of the thread groove of the adjusting screw 42 to form a limit, thereby fixing the insert 52 on the adjusting screw 42; when the end of the adjusting screw 42 is embedded in the threaded hole 411, the elastic force of the elastic strip 54 drives the connecting ring 51 close to the adjusting screw 42, and the insert 52 is embedded in the thread groove on the adjusting screw 42. The outer peripheral surface of the block 52 presses against the inner wall of the thread groove of the adjusting screw 42 to form a limit. The staff's finger presses against the surface of the force-applying part 532 and drives the force-applying part 532 to rotate, driving the rotating part 531 to rotate around its own axis, and driving the adjusting screw 42 to rotate around its own axis. The end of the adjusting screw 42 is penetrated by the threaded hole 1 411 and is screwed and fixed on the inner wall of the threaded hole 2 3121, thereby realizing the installation of the adjusting link 41 and the rotating link 2 312, so that the user does not need to use external tools to tighten the adjusting screw 42, thereby improving the convenience of using the float valve.

One end of the elastic member 61 in the elastic direction is connected to the inner wall of the rotating cavity 5321, and the other end of the elastic member 61 in the elastic direction is connected to the rotating shaft of the rotating rod 62. The elastic member 61 has the elastic force to drive the rotating rod 62 to rotate in the direction close to the fixed groove 3122, and the end of the rotating rod 62 tends to be embedded in the fixed groove 3122. The inner wall of the fixed groove 3122 abuts against the rod surface of the rotating rod 62 to form a limit, and limits the rotating part 531 to rotate in the inner circle of the connecting ring 51, so that the rotating part 531 is not easily rotated by external pressure, thereby ensuring that the end of the adjusting screw 42 is firmly tightened to the inner wall of the threaded hole 3121.

[0042] Reference Figure 3 and Figure 4The magnetic block 63 is fixed on the surface of the rotating rod 62 facing the fixed groove 3122, the electromagnet 64 is fixed on the inner wall of the fixed groove 3122 facing the magnetic block 63, and the induction switch 65 is fixed on the surface of the adjusting link 41 facing the adjusting screw 42. The induction switch 65 is electrically connected to the electromagnet 64. When the end of the adjusting screw 42 passes through the threaded hole 1 411 and is screwed and fixed on the inner wall of the threaded hole 2 3121, the induction switch 65 abuts the surface of the adjusting screw 42 and is turned on. The electromagnet 64 is energized and has magnetism. The electromagnet 64 and the magnetic block 63 are attracted and fixed by opposite poles, making it difficult for the rotating rod 62 to escape from the fixed groove 3122, thereby improving the limiting stability of the end of the rotating rod 62 in the fixed groove 3122.

[0043] Reference Figure 2 and Figure 3 The cam 74 is pressed against the engagement of the engagement member 71 with the engagement member 72 and the engagement member 73. The cam 74 is pressed against the engagement member 72 and the engagement member 73 is moved relative to the engagement member 73.

[0044] Reference Figure 2 and Figure 3 The side wall of the adjusting connecting rod 41 is provided with a detection cavity 413 for sliding of the positioning rack 2 72. The sliding direction of the positioning rack 2 72 and the sliding direction of the positioning rack 1 71 are perpendicular to each other. The detection cavity 413 is connected to the positioning cavity 412, and the positioning gear 73 is rotatably connected to the inner wall of the positioning cavity 412. The positioning rack 1 71 and the positioning rack 2 72 both engage with the tooth surface of the positioning gear 73; the material of the positioning ring capsule 74 can be rubber or silicone. In the embodiment of the present application, the material of the positioning ring capsule 74 is rubber, which has a certain deformation ability. The outer ring wall of the positioning ring capsule 74 is fixed on the inner wall of the threaded hole 1 411, and the inner ring wall of the positioning ring capsule 74 can abut against the outer ring wall of the adjusting screw 42. In the embodiment of the present application, the positioning rack 2 72 is equivalent to a piston, and the inner cavity of the positioning ring capsule 74 is connected to the detection cavity 413.

[0045] Reference Figure 2 and Figure 3When the end of the adjusting screw 42 passes through the threaded hole 1 411 and is threadedly fixed to the inner wall of the threaded hole 2 3121, the surface of the rotating connecting rod 2 312 abuts against the surface of the positioning rack 1 71 and drives the positioning rack 1 71 to slide toward the direction close to the positioning cavity 412. The positioning gear 73 rotates, driving the positioning rack 2 72 to slide toward the direction close to the detection cavity 413. The end face of the positioning rack 2 72 is flush with the side wall of the adjusting connecting rod 41. At the same time, the air pressure in the detection cavity 413 increases, and the air in the detection cavity 413 enters the inner cavity of the positioning ring bag 74. The inner ring wall of the positioning ring bag 74 is pressurized and expanded and presses against the outer circumferential surface of the adjusting screw 42 to form a limit, so that the adjusting screw 42 is not easily offset in the threaded hole 1 411, thereby improving the connection stability between the adjusting connecting rod 41 and the rotating screw rod 2.

[0046] The working principle of an adjustable float valve in the embodiment of the present application is as follows: when the water level in the container needs to be adjusted, the adjusting link 41 is driven to rotate about the axis of the adjusting screw 42, driving the float 43 to rotate about the adjusting screw 42, so that the height of the float 43 in the container cavity changes. When the float 43 is rotated to the required water storage height of the container, it stops. The second rotating link 312 rotates away from the valve body 1 due to its own gravity. The water in the drainage channel 11 passes through the inner ring of the plastic core 2 and the limiting cavity 3222 in sequence and is discharged from the drainage cavity 3221. The liquid level in the container continues to rise. When the surface of the float 43 abuts the fluid in the container, the float 43 rises due to the buoyancy of the fluid in the container, driving the second rotating link 312 to rotate toward the valve body 1. The surface of the plastic core 2 and the inner wall of the limiting cavity 3222 clamp the two sides of the gasket 321 to form a seal, thereby closing the valve body 1 and enabling the user to arbitrarily adjust the water level in the container, thereby improving the user's convenience in using the float valve.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
