Description

Technical Field

[0001] The present invention relates to the technical field of valves, in particular to an anti-leakage valve with an anti-blocking function. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems.

[0003] However, the existing anti-leakage valves with anti-blocking function still have certain problems when used:

[0004] There is a valve with Chinese patent application number CN201511031050.7, which includes: a valve body, which is a body of a normally open valve or a normally closed valve; a control unit, which is arranged on the valve body to control the opening and closing of the valve, and is provided with a perspective portion; a first display unit, which is mounted on the valve body and is provided with a first identification portion; a second display unit, which is mounted in the control unit, and includes a second identification portion and a third identification portion. When the control unit controls the opening and closing of the valve, the perspective unit sees through the second identification portion or the third identification portion, wherein when the perspective unit sees through the second identification portion, the valve body is in a correctly opened or closed state; when the perspective unit sees through the third identification portion, the valve body is in an incorrectly opened or closed state.

[0005] 1. Existing valves are usually equipped with a filter to filter sand and gravel impurities in the water flow. However, the filter will inevitably become clogged after long-term use. It is very easy to become clogged and requires frequent cleaning or replacement of the filter, which is inconvenient to use.

[0006] 2. Most existing ball valves or plate valves are very prone to wear after long-term use. When the valve is closed due to wear, leakage will inevitably occur. The reliability of use is poor and the service life is short.

[0007] In response to the above problems, an innovative design was carried out based on the original anti-leakage valve with anti-blocking function. Summary of the Invention

[0008] The purpose of the present invention is to provide a leakage-proof valve with an anti-clogging function to solve the problem raised in the above background technology that the existing valves will filter sand and gravel and become blocked during use, affecting the flow rate of water. At the same time, most of the existing valves will experience greater wear during use, and leakage will occur after long-term use, which also reduces the service life of the valve.

[0009] To achieve the above-mentioned object, the present invention provides the following technical solution: an anti-leakage valve with an anti-blocking function, comprising a valve body:

[0010] The left end of the valve body is fixed with a liquid outlet connection flange by bolts, and the right end of the valve body is fixed with a liquid inlet connection flange. The right side of the valve body is internally rotatably connected to the valve core shaft, and a sealing valve plate is fixed in the middle of the valve core shaft;

[0011] A filter mechanism is provided in the middle of the valve body, and the filter mechanism includes a positioning frame and a filter screen. The positioning frame is fixed inside the valve body, and a filter screen is fixed on the left side of the positioning frame. An auger shaft is provided in the middle of the filter screen, and rotating shafts are provided on both sides of the auger shaft, and a material stripping plate is connected to the outer wall of the rotating shaft;

[0012] A material storage mechanism is provided at the lower end of the valve body, and the material storage mechanism includes a material discharge box, a conduit and an isolation filter. The material discharge box is fixed to the lower end of the valve body, and the upper right end of the material discharge box is fixed to the conduit, and the conduit passes through the interior of the valve body;

[0013] A transmission mechanism is provided inside the left side of the valve body, and the transmission mechanism includes an impeller, and the impeller is rotatably connected to the inner wall of the valve body. A first mounting groove is provided at the upper end of the left side of the valve body, and the upper end of the first mounting groove extends to the inside of the first mounting groove. The transmission mechanism provides rotational power for the auger shaft and the rotating shaft when water flows inside the valve body.

[0014] Preferably, the sealing valve plate is rotatably connected to a positioning ring at both ends, and sealing strips are connected to the left and right sides of the positioning ring, and the two groups of sealing strips are symmetrically distributed with the valve core axis as the center axis, and the end of the sealing strip is fixedly connected to a sealing plate, and the sealing plates are symmetrically distributed at the front and rear ends of the valve core axis, and the sealing plates are fixedly connected to the inner wall of the valve body.

[0015] By adopting the above technical solution, the two sets of sealing strips and the sealing plate are connected by a positioning ring, and the sealing valve plate and the sealing strip are connected and positioned using the positioning strip. The valve core shaft can be rotated to control the rotation of the sealing valve plate and thus control the flow of the valve and control the opening and closing of the valve.

[0016] Preferably, the exterior of the sealing valve plate is made of rubber, and both ends of the sealing valve plate are respectively fitted and sealed with the sealing plate, and the upper and lower ends of the sealing valve plate are respectively fitted with the sealing strip.

[0017] By adopting the above technical solution, by covering the outside of the sealing valve plate with rubber material, when the sealing valve plate rotates and contacts the sealing plate and the sealing strip, it can effectively provide sealing, thereby improving the sealing effect of the valve and avoiding leakage. Compared with traditional ball valve and plate valve structures, this structure is not prone to wear and tear, and can increase the overall service life.

[0018] Preferably, a second mounting groove is opened at the upper right end of the valve body, and the upper end of the valve core shaft extends into the inside of the second mounting groove, and the valve core shaft is rotatably connected to the inner wall of the valve body, a transmission worm gear is fixed to the top end of the valve core shaft, and a transmission worm is rotatably connected to the left inner wall of the second mounting groove, and the transmission worm is meshed with the transmission worm gear, the front end of the transmission worm passes through the outside of the valve body, and the front end of the transmission worm is fixedly connected to a turntable.

[0019] By adopting the above technical solution, the transmission structure of the valve core shaft is installed through the second mounting groove. When in use, the transmission worm can be driven to rotate by rotating the turntable, and the transmission worm can be used to drive the transmission worm wheel and the valve core shaft to rotate, so as to adjust the hole to control the flow of the valve. Moreover, because the worm gear structure has a self-locking characteristic, it has better stability during adjustment, avoiding looseness and water leakage, thereby improving reliability.

[0020] Preferably, two groups of rubber sheets are connected to the right end of the positioning frame, and the rubber sheets are symmetrically distributed at the front and rear ends of the positioning frame. The two groups of rubber sheets are flexible in design, and the two groups of rubber sheets are designed in a "V" shape. The middle part of the filter screen is designed in a semicircular structure, and the auger shaft fits against the inner wall of the middle part of the filter screen.

[0021] By adopting the above technical solution, impurities can be blocked inside the positioning frame after entering through the blocking of two sets of rubber sheets. When the impurities flow into the positioning frame, they can be isolated by the filter net. The filter net is used to block the impurities and purify the water. At the same time, the design of the auger shaft can transport the isolated and filtered impurities downward during rotation, avoiding the blockage of the valve due to excessive impurities blocked by filtration.

[0022] Preferably, the rotating shaft is rotatably connected to the inner wall of the valve body, and the material-diverting plates are distributed in a circular array with the rotating shaft as the center. The two sides of the filter screen are designed in an arc shape, and the two sides of the filter screen are in contact with the outer wall of the material-diverting plate.

[0023] By adopting the above technical solution, through the cooperation of multiple sets of material-moving plates and the rotating shaft, the impurities on both sides of the filter screen can be continuously moved when the rotating shaft rotates, so as to push the impurities to move toward the middle of the filter screen, thereby facilitating the impurities to move toward the auger shaft for transportation and discharge from the interior of the valve body.

[0024] Preferably, an isolation filter is fixed in the middle of the discharge box, and a sealing cover is threadedly connected to the lower right end of the discharge box, the lower right end of the auger shaft extends to the inside of the conduit, and a one-way valve is connected to the upper left end of the discharge box, and the upper end of the one-way valve extends to the inside of the valve body.

[0025] By adopting the above technical solution, through the design of the conduit and the discharge box, impurities can be continuously transported to the inside of the discharge box when the auger shaft rotates. After the impurities are transported to the inside of the discharge box, they can be further blocked by the isolation filter, and the excess water transported to the inside of the discharge box at the same time is transported back to the inside of the valve body through the one-way valve.

[0026] Preferably, the impeller is adapted to the size of the inner wall of the valve body, and a bevel gear is fixed to the top of the impeller, a transmission shaft is rotatably connected to the inside of the first mounting groove, and a first bevel gear is connected to the left end of the transmission shaft, and the first bevel gear is meshed with the bevel gear, a second bevel gear is fixedly connected to the right side of the transmission shaft, the upper end of the auger shaft passes through the inside of the first mounting groove, and a third bevel gear is fixedly connected to the upper end of the auger shaft, and the third bevel gear is meshed with the second bevel gear.

[0027] By adopting the above technical solution, the impeller can be driven to rotate synchronously when water flows inside the valve body, and the impeller can be used to drive the bevel gear to rotate synchronously. When the bevel gear rotates, the first bevel gear can be used to drive the transmission shaft and the second bevel gear to rotate synchronously, and the second bevel gear can be used to drive the third bevel gear and the auger shaft to rotate synchronously, thereby providing rotational power for the impurity cleaning structure.

[0028] Preferably, the right end of the transmission shaft is fixedly connected to a second worm, the upper end of the rotating shaft passes through the inside of the first mounting groove, and the upper end of the rotating shaft is fixedly connected to a second worm wheel, and the second worm wheel is meshingly connected to the second worm.

[0029] By adopting the above technical solution, the rotation of the transmission shaft can drive the second worm to rotate synchronously, and the second worm can drive the second worm wheel to rotate synchronously, and the second worm wheel can provide rotational power for the rotating shaft. The rotation of the rotating shaft can drive multiple sets of material-moving plates to rotate synchronously, thereby moving the impurities inside the filter screen to the middle, thereby improving the efficiency of impurity discharge.

[0030] Preferably, the bottom end of the auger shaft extends to the inside of the discharge box, and the bottom end of the auger shaft is connected to a stirring rod, and the stirring rods are distributed in a ring array.

[0031] By adopting the above technical solution, the impurities stored in the discharge box can be stirred by the stirring rod connected to the bottom end of the auger shaft, thereby avoiding the isolation filter from being blocked too quickly, so as to reduce the frequency of replacement.

[0032] Compared with the prior art, the beneficial effects of the present invention are: the anti-leakage valve with anti-clogging function can filter the sand and gravel impurities carried in the liquid flowing in the valve by being provided with a filtering mechanism, and is also provided with a discharge structure to avoid blockage caused by excessive impurities retained by the filtration, and is also provided with a storage mechanism to store the sand and gravel impurities remaining after filtration to avoid the tediousness of frequent cleaning.

[0033] 1. The transmission mechanism can provide rotational power for the rotation of the auger shaft, rotating shaft and feed plate. When water flows inside the valve body, it drives the impeller to rotate, and uses structures such as bevel gears to drive the auger shaft feed plate to rotate. When the auger shaft rotates, it can discharge the sand and gravel impurities filtered and isolated by the filter screen and transport them to the inside of the discharge box, thereby avoiding obstruction of the water flow inside the valve.

[0034] 2. By setting up a discharge mechanism, the filtered sand and impurities can be temporarily stored, and the isolation filter can be used to further filter the water to ensure that the excess water can flow back to the inside of the valve body when the impurities are discharged. In conjunction with the rotation of the stirring rod, the impurities can be rotated inside the discharge box to avoid clogging the isolation filter. When there are too many impurities inside the discharge box, the sealing cover can be rotated to quickly clean the internal sand and gravel impurities, thereby improving the convenience of operation.
