Abstract
Description
Technical Field
[0001] This invention relates to the field of valve facilities, specifically to a valve with a warning function. Background Technology
[0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems and have functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.
[0003] Most existing valves develop leaks over time during use, which can be internal or external. Internal leakage refers to the valve failing to close completely due to erosion or wear from the medium; even with the valve screw tightened, gaps remain between the valve core and body, allowing the medium to flow through. External leakage refers to the medium leaking out of the conduit due to a poor seal between the valve and the connecting flange or threads. Most valves lack leak warning devices, failing to promptly alert personnel for maintenance, potentially leading to larger leaks and jeopardizing production safety. Furthermore, existing warning devices cannot immediately distinguish between internal and external leaks, reducing maintenance efficiency and increasing repair time. Summary of the Invention

[0028] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0029] Please see Figures 1-10 The present invention provides a technical solution: a valve with a warning function, including a main pipe 1, a branch pipe 2 and a valve body 8. The main pipe 1 has branch pipes 2 connected to both sides of its outer wall. The valve body 8 is located inside the main pipe 1 between the two branch pipes 2. An external leakage warning mechanism 6 is fixedly connected to the main pipe 1 at the valve body 8. A flow guiding mechanism 7 is provided between the external leakage warning mechanism 6 and one of the branch pipes 2. An internal leakage warning mechanism 3 is provided on the main pipe 1 between the valve body 8 and the other branch pipe 2.
[0030] The internal leakage warning mechanism 3 includes a ring 31 fixed to the outer wall of the main pipe 1. A trapezoidal block 32 is movably inserted into the ring 31, and a first spring 34 is fixed to one end of the trapezoidal block 32 located inside the ring 31. A gear 35 is meshed with one side of the trapezoidal block 32 and is rotatably connected to the ring 31. A turntable 36 is meshed with the lower side of the gear 35 and is rotatably connected to the main pipe 1. An eccentric collar 37 is fixed to the inner wall of the turntable 36 inside the main pipe 1. The valve body 8 is located on the main pipe 1. A protrusion 33 is fixedly connected to one side wall of the outer ring 31. A monitoring mechanism 39 is provided on the outer wall of the ring 31. The monitoring mechanism 39 includes a connecting block 391 fixedly connected to the outer wall of the ring 31 and a first alarm 392. A water storage tank 38 is fixedly connected to the lower outer wall of the ring 31. A float plate 312 is provided inside the water storage tank 38. A push rod 313 is fixedly connected to the upper end of the float plate 312. The push rod 313 is movably inserted into the upper end of the water storage tank 38. The push rod 313 is located directly below the top rod 394. A rubber stopper 311 is provided at the bottom of the water storage tank 38.
[0031] Specifically, when the valve body 8 is in the open state, the protrusion 33 squeezes the trapezoidal block 32. Through the rotation between the trapezoidal block 32, the gear 35 and the turntable 36, the eccentric collar 37 rotates, causing the bottom of the eccentric collar 37 to block the connection between the main pipe 1 and the water storage tank 38. When the valve body 8 is in the closed state, the protrusion 33 separates from the trapezoidal block 32, causing the eccentric collar 37 to rotate, connecting the water storage tank 38 at the bottom of the eccentric collar 37 to the main pipe 1. If the valve leaks internally at this time, the water leaking from the other end of the valve flows into the water storage tank 38 through the water guide groove 310. After the water has flowed for a period of time, the float plate 312 in the water storage tank 38 floats up, and the push rod 313 moves the switch 395. When the valve leaks externally, the external leakage warning mechanism 6 can remind the staff to repair it. The excessive external leakage liquid can be guided into the branch pipe 2 near the inlet 4 through the flow guide mechanism 7.
[0032] In another embodiment of the present invention, a sliding groove 396 is provided on the side wall of the connecting block 391, and a top rod 394 is slidably connected in the sliding groove 396. A second spring 397 is fixed between the upper wall of one end of the top rod 394 located in the sliding groove 396 and the connecting block 391. A switch 395 is provided on the side wall of the first alarm 392 near the top rod 394, and a first warning light 393 is provided on the upper end of the first alarm 392.
[0033] Specifically, when the float plate 312 rises, the push rod 313 pushes the top rod 394 upward, thereby moving the switch 395, and then the first warning light 393 lights up.
[0034] In another embodiment of the present invention, the external leakage warning mechanism 6 includes a liquid guiding sleeve 61 fixed to the outer wall of the main pipe 1. A water storage cavity 62 is provided inside the liquid guiding sleeve 61. A circular hole 63 is provided at the upper end of the liquid guiding sleeve 61. A guide groove 64 is provided on the inner wall of the water storage cavity 62 near the internal leakage warning mechanism 3. A fixing block 65 and a second alarm 66 are fixedly connected to the outer wall of the main pipe 1 between the liquid guiding sleeve 61 and the ring sleeve 31. The guide groove 64 communicates with the inner cavity of the fixing block 65. A float 611 is provided inside the fixing block 65. A connecting rod 69 is fixedly connected to the upper end of the float 611. The connecting rod 69 is movably inserted into the upper end of the fixing block 65. A conductive block 610 is provided at one end of the connecting rod 69 outside the fixing block 65. A slot is provided on the lower surface of the second alarm 66 directly above the connecting rod 69. A conductive plate 68 is provided in the slot. A second warning light 67 is provided at the upper end of the second alarm 66.
[0035] Specifically, when the valve leaks, water will leak out at the connection between the valve body 8 and the main pipe 1. The leaked water will flow into the water storage chamber 62 and into the fixed block 65 from the guide groove 64. As a result, the float 611 floats upward, causing the conductive block 610 to come into contact with the conductive plate 68, thereby illuminating the second warning light 67.
[0036] In another embodiment of the present invention, the flow guiding mechanism 7 includes a flow channel 75 opened at the bottom of one side of the water storage chamber 62, a conduit 71 communicating between the liquid guiding sleeve 61 and a branch pipe 2 away from the ring sleeve 31, and the conduit 71 communicating with the flow channel 75, a trapezoidal rod 72 slidably arranged inside the liquid guiding sleeve 61, a baffle 73 fixedly connected to the lower end of the trapezoidal rod 72, and the baffle 73 movably inserted into the liquid guiding sleeve 61, a third spring 74 fixedly connected between the end of the baffle 73 away from the fixed block 65 and the liquid guiding sleeve 61, and one end of the trapezoidal rod 72 movably inserted into the fixed block 65.
[0037] Specifically, when there is too much external leakage, the float 611 continues to rise, pressing the trapezoidal rod 72 to one side, thereby causing the baffle 73 to move. Then, the drainage channel 75 is connected to the water storage chamber 62, and the liquid flows into the branch pipe 2 through the drainage channel 75 and the conduit 71.
[0038] In another embodiment of the present invention, the baffle 73 is located at the upper end of the diversion groove 75, and a plurality of third springs 74 are provided, with the plurality of third springs 74 being distributed at equal intervals.
[0039] In another embodiment of the present invention, a water guide groove 310 is provided on the lower inner wall of the ring 31 located on the lower side of the eccentric ring 37, and the water guide groove 310 is in communication with the water storage device 38.
[0040] Specifically, the water leaking from the other end of the valve flows into the water storage tank 38 through the water guide channel 310.
[0041] In another embodiment of the present invention, the main pipe 1 is provided with an inlet 4 at one end near the conduit 71, and an outlet 5 at the other end of the main pipe 1.
[0042] In another embodiment of the present invention, when the valve body 8 is in the open state, the protrusion 33 abuts against the trapezoidal block 32.
[0043] Working principle: When the valve body 8 is in the open state, the protrusion 33 squeezes the trapezoidal block 32. Through the rotation between the trapezoidal block 32, the gear 35, and the turntable 36, the eccentric collar 37 rotates, causing the bottom of the eccentric collar 37 to block the water guide groove 310. When the valve body 8 is in the closed state, the protrusion 33 separates from the trapezoidal block 32, causing the eccentric collar 37 to rotate. This connects the water guide groove 310 at the bottom of the eccentric collar 37 to the main pipe 1. If there is internal leakage in the valve at this time, the water leaking from the other end of the valve flows into the water storage tank 38 through the water guide groove 310. After the water has flowed in for a period of time, the float plate 312 in the water storage tank 38 rises. When the valve floats upward, the push rod 313 pushes the top rod 394 upward, thereby moving the switch 395. Then the first warning light 393 lights up. When the valve leaks, water will leak out at the connection between the valve body 8 and the main pipe 1. The leaked water will flow into the water storage chamber 62. The leaked water flows into the fixed block 65 from the guide groove 64, causing the float 611 to float upward. This causes the conductive block 610 to contact the conductive plate 68, thereby lighting up the second warning light 67. When there is too much leakage, the float 611 continues to float upward, pressing the trapezoidal rod 72 to one side, thereby moving the baffle 73. Then the drainage groove 75 is connected to the water storage chamber 62, and the liquid flows into the branch pipe 2 through the drainage groove 75 and the guide pipe 71.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
