Description

Technical Field

[0001] The present invention relates to the technical field of liquid-sealed valves, in particular to liquid-sealed valves. Background Art

[0002] Liquid-sealed valves are a key component widely used in the field of fluid control. They are often used in drainage systems, pipeline flow control, and fluid separation. Traditional liquid-sealed devices have certain limitations in dealing with bubble separation and water flow regulation: on the one hand, since bubbles in the water flow cannot be discharged in time, the gas may react with minerals in the water after entering the pipeline to form sediments, causing pipeline blockage or reducing drainage efficiency; on the other hand, when facing different water flow rates, traditional devices are difficult to balance efficient drainage and liquid-sealing effects. Especially under conditions where the water flow rate varies greatly, liquid seal failure or poor drainage is prone to occur.

[0003] In view of the above problems, developing a liquid-sealed valve that can dynamically adjust the liquid seal volume, effectively eliminate bubbles, and adapt to different flow conditions has become an urgent technical demand. This device needs to achieve dynamic adjustment in structure while ensuring the accuracy of fluid control and long-term operation stability, so as to meet the application needs of multiple scenarios.

[0004] The existing Chinese patent with publication number: CN222150975U discloses a liquid bubble elimination device, which is designed to efficiently remove bubbles in liquid. The device is composed of a defoaming chamber, including an overflow chamber, a water inlet chamber and a water outlet chamber. The water inlet chamber is connected to the overflow chamber through an overflow port, and is connected to the water outlet chamber through a water outlet. The overflow chamber, the water inlet chamber and the water outlet chamber are respectively provided with an overflow hole, a water inlet hole and a water outlet hole on the cavity wall. When liquid enters the water inlet chamber through the water inlet hole, the amount of water entering is greater than the amount of water flowing out through the water outlet hole, and the excess liquid is discharged through the overflow hole. In addition, the bottom edge of the water outlet is lower than the bottom edge of the overflow port. Through the height difference between the overflow port and the water outlet, the device can switch the liquid flow path, so that the water flow containing bubbles flows to the overflow port, and the water flow without bubbles flows to the water outlet, thereby effectively eliminating bubbles in the liquid. However, the device cannot be applied to the inside of a smaller pipeline, and cannot be adjusted accordingly for different flow rates.

[0005] Therefore, it is necessary to design a liquid-sealed valve that is practical, can remove bubbles from the fluid, and can adapt to different flow rates of water. Summary of the invention

[0006] The object of the present invention is to provide a liquid-sealed valve to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a liquid-sealed valve, comprising a water valve, an exhaust pipe fixedly connected to the upper side of the water valve, the upper side of the exhaust pipe being connected to the interior of the water valve through the exhaust pipe, the interior of the water valve being a channel structure penetrating from left to right, a water retaining platform being provided on the inner left part of the water valve and the inner right part of the water valve, a cavity being provided on the lower side of the water retaining platform, an adjusting mechanism being provided on the outer side of the water valve, a baffle being fixedly connected to the middle part of the upper side of the inner wall of the water valve, and a sealing mechanism being provided on the right side of the baffle inside the water valve.

[0008] According to the above technical solution, the sides of the water retaining platforms on both sides inside the water valve close to the middle of the water valve are inclined, a groove is formed in the middle of the water retaining platforms on both sides inside the water valve, the baffle is located on the upper side of the middle of the groove, the upper surface height of the left water retaining platform inside the water valve is higher than the upper surface height of the right water retaining platform inside the water valve, and the lower end height of the baffle is lower than the upper surface height of the right water retaining platform inside the water valve.

[0009] According to the above technical solution, the regulating mechanism includes a first film, which is an elastic film. The first film is arranged inside the cavity on the lower side of the water retaining platform, and the outer wall of the first film is fixedly connected to the inner wall of the cavity on the side close to the middle of the water valve. Two first films are provided. The regulating mechanism also includes a fixed head, which is located on the lower side of the water valve, and the outer wall of the fixed head is fixedly connected to the inner wall of the water valve. The fixed head connects the interior of the cavity on the lower side of the water retaining platform with the lower exterior of the water valve. A connecting pipe is fixedly connected to the lower side of the fixed head, and an air pump is fixedly connected to the outer wall of the water valve. The other end of the connecting pipe is fixedly connected to the output end of the air pump, and the output end of the air pump is connected to the interior of the cavity through the connecting pipe and the fixed head.

[0010] According to the above technical solution, the sealing mechanism includes a fixed frame, the upper side of the fixed frame is fixedly connected to the upper side of the inner wall of the water valve, the inner wall of the fixed frame is slidably connected with a sliding rod, the upper end of the sliding rod is fixedly connected with a sealing cover, the lower end of the sliding rod is fixedly connected with a tachometer, a rotating frame is arranged on the outside of the tachometer, the outer wall of the rotating frame is hinged with a connecting plate, the other end of the connecting plate is fixedly connected with a pressure strip, and the outer wall of the rotating frame is also fixedly connected with a protrusion.

[0011] According to the above technical solution, the diameter of the cover is larger than the inner wall diameter of the exhaust pipe, and the length of the connecting plate is larger than the distance between the outer wall of the rotating frame and the outer wall of the first film located on the right side.

[0012] According to the above technical solution, a water trough is opened on the right side of the inner wall of the water valve, the left side of the inner part of the water trough is connected with the inside of the right side of the cavity inside the water valve through a circular hole, and a second film is fixedly connected to the inner wall of the circular hole.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The present invention provides a technical solution: a liquid-sealed valve, comprising a water valve 1, an exhaust pipe 2 is fixedly connected to the upper side of the water valve 1, the upper side of the exhaust pipe 2 is connected to the inside of the water valve 1 through the exhaust pipe 2, the inside of the water valve 1 is a channel structure that penetrates from left to right, a water retaining platform is provided at the inner left part of the water valve 1 and the inner right part of the water valve 1, a cavity is provided at the lower side of the water retaining platform, an adjusting mechanism 3 is provided at the outer side of the water valve 1, a baffle 4 is fixedly connected to the middle part of the upper side of the inner wall of the water valve 1, and a blocking mechanism 5 is provided at the right side of the baffle 4 inside the water valve 1;

[0027] The sides of the water retaining platforms on both sides of the water valve 1 close to the middle of the water valve 1 are inclined, and a groove is formed in the middle of the water retaining platforms on both sides of the water valve 1. The baffle 4 is located on the upper side of the middle of the groove. The upper surface height of the left water retaining platform inside the water valve 1 is higher than the upper surface height of the right water retaining platform inside the water valve 1. The lower end height of the baffle 4 is lower than the upper surface height of the right water retaining platform inside the water valve 1.

[0028] During use of the device, water flows into the right side of the water valve 1, and enters the groove area in the middle of the water valve 1 through the holes that penetrate the left and right sides. When the water flows to the left through the recess in the middle of the water valve 1, since the lower part of the baffle 4 is arranged above the groove, the liquid level of the water flow will be higher than the lower position of the baffle 4, thereby effectively blocking the right side of the airflow from diffusing to the left. At the same time, the bubbles in the water flow will float up under the action of buoyancy, gradually gather at the exhaust pipe 2, and be smoothly discharged through the exhaust pipe 2, so as to achieve the effect of efficiently eliminating bubbles in the water flow. This process can not only prevent the gas from entering the subsequent drainage pipe and reacting with the minerals in the water, but also effectively prevent the blockage problem caused by the formation of sediment inside the pipe, thereby ensuring the smooth operation and stability of the drainage system in the long term;

[0029] The regulating mechanism 3 includes a first film 301, which is an elastic film. The first film 301 is arranged inside the cavity on the lower side of the water retaining platform, and the outer wall of the first film 301 is fixedly connected to the inner wall of the cavity near the middle of the water valve 1. Two first films 301 are provided. The regulating mechanism 3 also includes a fixed head 302, which is located on the lower side of the water valve 1, and the outer wall of the fixed head 302 is fixedly connected to the inner wall of the water valve 1. The fixed head 302 connects the interior of the cavity on the lower side of the water retaining platform with the lower exterior of the water valve 1. A connecting pipe 303 is fixedly connected to the lower side of the fixed head 302, and an air pump 304 is fixedly connected to the outer wall of the water valve 1. The other end of the connecting pipe 303 is fixedly connected to the output end of the air pump 304, and the output end of the air pump 304 is connected to the interior of the cavity through the connecting pipe 303 and the fixed head 302.

[0030] During the operation of the device, the gas in the cavity of the water valve 1 can be adjusted by starting the air pump 304. When the air pump 304 pumps air into the cavity through the connecting pipe 303 and the fixed head 302, the first film 301 will gradually expand, thereby occupying the groove in the middle of the water valve 1 and reducing the volume of the groove; conversely, when the gas inside the cavity is extracted, the first film 301 is sunken downward, so that the passing volume of the groove is increased. In the case of a large water flow rate, the flow capacity of the groove channel can be expanded by adjusting the degree of depression of the first film 301, thereby effectively meeting the discharge demand of a large flow of water; and when the water flow rate is small, the volume of the groove is reduced by expanding the first film 301 to ensure that a small water flow can also form a reliable liquid sealing effect at the groove. Therefore, the device can flexibly adjust the volume of the groove under different water flow conditions to ensure the stability of the liquid sealing performance and the efficiency of drainage.

[0031] The blocking mechanism 5 includes a fixing frame 501, the upper side of the fixing frame 501 is fixedly connected to the upper side of the inner wall of the water valve 1, the inner wall of the fixing frame 501 is slidably connected with a slide bar 502, the upper end of the slide bar 502 is fixedly connected with a cover 503, the lower end of the slide bar 502 is fixedly connected with a tachometer 504, a rotating frame 505 is arranged on the outer side of the tachometer 504, the outer wall of the rotating frame 505 is hinged with a connecting plate 506, the other end of the connecting plate 506 is fixedly connected with a pressure strip 507, the outer wall of the rotating frame 505 is also fixedly connected with a convex piece 508, the diameter of the cover 503 is larger than the inner wall diameter of the exhaust pipe 2, and the length of the connecting plate 506 is larger than the distance between the outer wall of the rotating frame 505 and the outer wall of the first film 301 located on the right side;

[0032] During the use of the device, since the water flows in from the right side, the water flow provides buoyancy to the structures such as the slide bar 502 and the rotating frame 505, so that the cover 503 is located above the liquid surface. When the water flow is too large, the cover 503 will be lifted up by the slide bar 502 to block the lower end of the exhaust pipe 2, thereby causing bubbles to gather on the right side of the baffle 4, resulting in a reduction in the water flow, which can prevent the water flow inside the water valve 1 from overflowing outwards, and can reduce the amount of bubbles driven to the left by the excessively fast water flow rate. In addition, the water flow can impact the convex piece 508 on the outside of the rotating frame 505 to rotate the rotating frame 505. During the rotation of the rotating frame 505, the rotating speed of the rotating frame 505 will be sent to the receiving terminal through the tachometer 504, so that the user can grasp the water flow state inside the water valve 1.

[0033] A water tank 305 is provided on the right side of the inner wall of the water valve 1. The left side of the inner part of the water tank 305 is connected to the inside of the right side of the inner cavity of the water valve 1 through a circular hole. A second film 306 is fixedly connected to the inner wall of the circular hole.

[0034] When the water flow hits the rotating frame 505, the rotating frame 505 drives the connecting plate 506 and the pressure strip 507 to rotate. When the pressure strip 507 rotates to the first film 301, it squeezes the outer wall of the first film 301, causing the gas pressure inside the cavity to gradually increase. As the gas pressure in the cavity increases, the second film 306 is pushed to the right, so that the second film 306 expands to the right and squeezes the water inside the water tank 305, so that the water inside the water tank 305 is discharged upward, forming a vertical thrust, further accelerating the floating process of the bubbles inside the water flow. This structural design can improve the discharge efficiency of the bubbles. When the pressure strip 507 continues to rotate and separate from the first film 301, the pressure of the water inside the water tank 305 will cause the first film 301 to rebound, and the water inside the water tank 305 will be refilled with water.
