Description

Technical Field

[0001] This utility model relates to the field of valve body technology, and in particular to an anti-leakage automatic alarm water valve. Background Technology

[0002] Water valves, as essential components for controlling water flow, are widely used in household, commercial, and industrial facilities. However, due to factors such as increased service life, material aging, improper installation, or external stress, water valves themselves can also become the source of water leakage accidents.

[0003] Currently, Chinese utility model patent CN217815006U, published on June 21, 2022, discloses a leak-proof remote alarm valve, comprising: a valve body, a valve cover, a water supply pressure gauge, a system pressure gauge, a filter, a drain valve, a delay device, an alarm bell, and a pressure switch. The valve body contains a valve disc assembly for sealing the valve body and a support assembly for supporting the valve disc assembly. The support assembly is located above the valve disc assembly relative to the valve body. One end of the support assembly is detachably connected to the inner wall of the valve body, and the other end is detachably connected to the valve disc assembly. The support assembly effectively compresses the valve disc within the valve body.

[0004] Regarding the aforementioned technologies, if additional pressure is forcibly applied between the valve disc and the valve body when the valve disc is closed, it can improve the sealing performance to some extent. However, during long-term use of the valve body, the additional force will cause the valve disc to deform prematurely, increasing the risk of leakage. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic alarm water valve that reduces valve body leakage.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An automatic alarm water valve for preventing leakage includes a main body, an adjusting mechanism, a detection mechanism, and a valve core mechanism. The adjusting mechanism includes an adjusting rod that is rotatably mounted on the main body. The detection mechanism includes a flow sensor that is fixedly installed inside the valve cavity of the main body.

[0008] The valve core mechanism includes a valve ball and a mounting base. One mounting base is fixedly installed at the top and bottom of the valve ball. One mounting base is throttle-connected to the adjusting rod, and the other mounting base is rotatably connected to the inside of the main body.

[0009] The arc-shaped center of the valve ball and the rotation center of the adjusting rod are offset by a first offset distance along the flow direction of the channel;

[0010] The main body has an abutment part inside, and the abutment part has an arc-shaped abutment surface. The valve ball abuts against the abutment part to close the channel.

[0011] Optionally, the center of the arc of the valve ball is provided with a second offset distance along the direction perpendicular to the flow of the channel.

[0012] Optionally, the abutting portion further includes a sealing ring and a first elastic member, the first end of the first elastic member being fixedly connected to the main body, and the second end of the first elastic member being fixedly connected to the end of the sealing ring away from the valve ball.

[0013] Optionally, the abutting portion further includes a second elastic member, the first end of which is fixedly connected to the main body, and the second end of which is fixedly connected to the outer end face of the sealing ring.

[0014] Optionally, the abutting part further includes a retaining ring, which is fixedly connected to the outer end face of the sealing ring, and the retaining ring is fixedly connected to the main body by bolts.

[0015] Optionally, the abutting portion further includes a third elastic member, which is fixedly disposed between the main body and the fixing ring.

[0016] Optionally, the abutting part further includes a guide ring, one end of which is fixedly connected to the main body.

[0017] Optionally, the adjusting mechanism further includes a locking sleeve, which is threadedly connected to the adjusting rod.

[0018] Optionally, the adjustment mechanism further includes an adjustment wristband, which is fixedly connected to the end of the adjustment rod away from the valve ball.

[0019] Optionally, the detection mechanism further includes a pressure sensor, the outer end of which is fixedly connected to the main body, the detection end of which is fixedly connected to the outer end face of the bearing that fixes the adjusting rod, and the pressure sensor is electrically connected to the flow sensor.

[0020] This utility model has the following beneficial effects:

[0021] 1. When the valve ball is closed, a uniform clamping force is generated, significantly improving sealing performance. The arc-shaped contact surface of the contact part fits tightly with the valve ball, and the rigid fixation of the retaining ring and bolts ensures that zero leakage is maintained during long-term use. The introduction of the guide ring further stabilizes the movement trajectory of the valve ball, avoiding sealing failure caused by uneven wear, and achieving high reliability and leakage prevention overall.

[0022] 2. The testing agency employs a dual monitoring scheme using flow and pressure sensors: the flow sensor directly detects abnormal water flow in the pipeline, while the pressure sensor indirectly determines whether the valve core is stuck or the seal has failed by monitoring the condition of the regulating rod bearing. The electrical signals from the two sensors are linked, which can trigger an alarm in real time or link with the control system to automatically close the valve, forming an active safety protection system that significantly reduces the risk of leakage accidents.

[0023] 3. The first elastic element, the second elastic element, the third elastic element, and the buffer design effectively absorb the closing impact and reduce the wear of the seal. Attached Figure Description

Detailed Implementation

[0031] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] This utility model discloses an automatic alarm water valve for preventing leakage. (See attached diagram.) Figure 1 To be continued Figure 6 An automatic alarm water valve for preventing leakage mainly includes a main body 100, an adjusting mechanism 200, a detection mechanism 300, and a valve core mechanism 400. The adjusting mechanism 200 includes an adjusting rod 210, which is rotatably mounted on the main body 100 via a bearing. The detection mechanism 300 includes a flow sensor 310, which is fixedly installed in the valve cavity 600 of the main body 100. The valve cavities 600 in the main body along the medium conveying direction respectively include a first connecting cavity 610, an adjusting cavity 630, and a second connecting cavity 620. The valve core mechanism 400 includes a valve ball 410 and a mounting base 420. A mounting base 420 is fixedly installed at the top and bottom of the valve ball 410. The mounting base 420 at the top of the valve ball 410 is connected to the adjusting rod 210 via a transmission connection, while the mounting base 420 at the bottom of the valve ball 410 is rotatably connected to the interior of the main body 100 via a bearing. The arc-shaped rotation axis of the valve ball 410 along the flow direction of the channel has a first offset distance 'a' from the rotation axis of the adjusting rod 210. An abutment portion 500 is provided inside the main body 100, and an arc-shaped abutment surface 570 is provided on the abutment portion 500. The abutment portion 500 is made of elastic material, and the valve ball 410 abuts against the abutment portion 500 to close the channel. The tight fit between the valve ball 410 and the abutment portion 500 ensures the sealing performance in the closed state and reduces the risk of leakage.

[0034] The flow sensor 310 monitors the water flow in real time. When abnormal flow (such as leakage) is detected while the water valve is closed, an alarm signal is triggered and sent to an alarm or buzzer to remind personnel to perform maintenance. The valve ball 410 is rotated by the adjusting rod 210 to achieve precise flow regulation. The rotation axis of the arc-shaped center of the valve ball 410 is set with a first offset distance 'a' between the rotation axis of the adjusting rod 210 and the rotation center axis. This allows the outer arc surface of the valve ball 410 to gradually pre-tighten with the contact part 500 during rotation, achieving an offset seal, enhancing the clamping force when closed, and improving the sealing effect. At the same time, when the pre-tightening is in place, it not only provides a good sealing effect but also reduces the possibility of over-tightening of the contact part 500, reducing the possibility of excessive compression and deformation of the contact part 500, and extending the service life of the water valve.

[0035] See attached document Figure 4In some embodiments, the arcuate center of the valve ball 410 is perpendicular to the direction of flow in the channel. Figure 4 A second offset distance b is provided in the X direction. This allows the valve ball 410 to form a more uniform contact pressure with the abutment surface 570 when closed, avoiding one-sided wear and extending service life. Utilizing the second offset distance b, in the closed state, the arc surface of the valve ball 410 contacts the abutment surface 570 of the abutment part 500, with the arc-shaped center of the valve ball 410 protruding from the inner ring of the abutment part 500, providing a certain limiting effect and reducing the risk of leakage from the valve ball 410.

[0036] See attached document Figure 2 To be continued Figure 4 In some embodiments, the abutment portion 500 includes a sealing ring 510 and a first elastic member 520. A rectangular groove 700 is formed in the adjustment cavity 630 inside the main body 100. The first end of the first elastic member 520 is fixedly connected to the main body 100. The first elastic member 520 can be fixed in the rectangular groove by snap-fit. The second end of the first elastic member 520 is fixedly connected to the end of the sealing ring 510 away from the valve ball 410. The fixing method can be adhesive or bolt fixing. The abutment surface 570 is formed on the outer end face of the sealing ring 510. The first elastic member 520 provides axial (axial direction of the pipeline) preload, which improves the tightness of the fit between the valve ball 410 and the sealing ring 510. At the same time, during the rotation of the valve ball 410, it reduces the possibility of hard contact between the sealing ring 510 and the arc surface of the valve ball 410, and reduces the possibility of wear on the outer arc surface of the valve ball 410.

[0037] See attached document Figure 3 In some embodiments, the abutment portion 500 further includes a second elastic member 530. The first end of the second elastic member 530 is fixedly connected to the main body 100, and the second end of the second elastic member 530 is fixedly connected to the outer end face of the sealing ring 510. The second elastic member 530 is located within the rectangular groove 700, and is perpendicular to the first elastic member 520. The second elastic member 530 and the first elastic member 520 can be integrally molded by injection molding. This improves the installation stability of the second elastic member 530 and the first elastic member 520.

[0038] See attached document Figure 3 In some embodiments, the abutment portion 500 further includes a retaining ring 540, which is fixedly connected to the outer end face of the sealing ring 510. The retaining ring 540 is fixedly connected to the main body 100 by bolts. The fixing method of the retaining ring 540 and the bolts enhances the stability of the sealing ring 510 and prevents elastic failure after long-term use.

[0039] See attached document Figure 3In some embodiments, the abutment portion 500 further includes a third elastic element 550, which is fixedly disposed between the main body 100 and the retaining ring 540. The third elastic element 550, sandwiched between the main body 100 and the retaining ring 540, plays a certain buffering role when the retaining ring 540 is installed, reducing the possibility of over-tightening the retaining ring 540, providing a certain pre-tightening force, and further providing resistance to axial impact.

[0040] See attached document Figure 4 and attached Figure 5 In some embodiments, the abutment portion 500 further includes a guide ring 560. One end of the guide ring 560 is fixedly connected to the main body 100 by bolts or snap-fit, and the other end (inner end) of the guide ring 560 abuts against the fixing ring 540. During the contact between the sealing ring 510 and the valve ball 410, the guide ring 560 can limit the movement adjustment direction of the sealing ring 510 to axial movement, reducing the possibility of lateral deviation of the sealing ring 510, reducing the possibility of leakage, and reducing the possibility of uneven force on the sealing ring 510. By using the guide ring 560, the position of the sealing ring 510 can be adjusted by adjusting the installation position of the guide ring 560. When deformation or installation errors occur, the sealing capacity of the sealing ring 510 can be adjusted more conveniently by adjusting the position of the guide ring 560.

[0041] See attached document Figure 1 In some embodiments, the regulating mechanism 200 further includes a locking sleeve 220, which is threadedly connected to the regulating rod 210. The locking rotation direction of the locking sleeve 220 is opposite to the rotation direction of the regulating rod 210 when it is in the open-closed state. This ensures that when the water valve is closed, if the regulating rod 210 rotates in the open-closed direction due to water pressure impact or loosening, the locking sleeve 220 can further press against the regulating rod 210 and the main body 100, reducing the possibility of the regulating rod 210 rotating and further reducing the possibility of leakage; preventing the regulating rod 210 from loosening due to vibration or water pressure fluctuations, and ensuring stable valve opening.

[0042] See attached document Figure 1 In some embodiments, the adjustment mechanism 200 further includes an adjustment wristband 230, which is fixedly connected to the end of the adjustment rod 210 away from the valve ball 410. This facilitates manual operation and improves the user experience.

[0043] See attached document Figure 2In some embodiments, the detection mechanism 300 further includes a pressure sensor 320. The outer end of the pressure sensor 320 is fixedly connected to the main body 100, and the detection end of the pressure sensor 320 is fixedly connected to the outer end face of the bearing of the fixed adjusting rod 210. The pressure sensor 320 is electrically connected to the flow sensor 310. By monitoring the pressure change at the bearing of the adjusting rod 210, the valve core status can be indirectly determined. For example, by detecting changes in the rotational resistance or force of the adjusting shaft, it can detect whether there is jamming or sealing failure. When the flow or pressure is abnormal, an alarm can be triggered or the valve can be automatically closed to improve safety.

[0044] The implementation principle of the leak-proof automatic alarm water valve in this embodiment of the utility model is as follows:

[0045] The offset design of the valve ball 410 and the multi-elastic sealing structure achieve excellent sealing performance. When the valve ball 410 is closed, it fits tightly with the arc-shaped contact surface 570 to form a uniform clamping force. The rigid fixation of the fixing ring 540 and bolts ensures long-term zero leakage. At the same time, a dual monitoring scheme of flow sensor 310 and pressure sensor 320 is adopted to detect water flow abnormalities and valve core status in real time. The electrical signal linkage can trigger an alarm or automatically close the valve. The regulating mechanism 200 achieves stable and precise flow control through locking sleeve 220 and regulating hand ring 230. The guide ring 560 ensures the stability of valve ball 410 movement. The third elastic element 550 absorbs the closing impact. The overall structure combines convenient operation and long-term durability, and is particularly suitable for working conditions with high requirements for sealing and safety.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
