Description

Technical Field

[0001] The present invention relates to the technical field of valves, and more particularly to an intelligent building valve that prevents scaling and jamming. Background Art

[0002] The building ball valve is a key control device installed on the main water supply pipeline of residential or commercial buildings. It is mainly used to open and close the water flow, adjust the flow rate, or isolate pipeline sections for maintenance. Its core component is a sphere with a through-hole, which realizes quick opening and closing through a 90-degree rotation.

[0003] After retrieval, a Chinese patent with the publication number CN220185881U discloses an anti-scaling ball valve, which includes a sphere with a bore diameter. The sphere is placed in the inner cavity of the valve body. The valve body is an integrally formed seamless structure. An installation opening is provided at the upper part of the valve body, and the valve cover is covered and connected to the installation opening. The valve stem passes through the valve cover and is connected to the upper part of the sphere. A horizontally arranged sealing ring is fixed at the lower part of the inner cavity of the valve body and is in sealing contact with the lower surface of the sphere. A horizontally arranged sealing ring is also fixed on the inner wall of the valve cover and is in sealing contact with the upper surface of the sphere, forming a sealing and anti-scaling structure for the upper and lower surfaces of the sphere.

[0004] Based on the above retrieval and combined with practical problems, it is found that although this ball valve reduces the gap between the valve ball and the valve body by setting a sealing structure, thereby reducing the generation of scale in the gap and achieving a certain anti-jamming effect, in actual application, most of the surface area of the valve ball will directly contact the water in the pipeline. When a layer of scale covers the surface of the valve ball, this ball valve cannot automatically clean the scale on the surface of the valve ball. When the valve ball is rotated to open and close the valve, the scale on the surface of the valve ball will directly rub against the sealing ring, further increasing the rotational resistance of the valve ball, and thus easily causing the jamming of the ball valve.

Detailed implementation manners

[0032] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention provides an intelligent building valve for preventing scale formation and jamming by improvement. The technical solution of the present invention is:

[0034] As Figures 1 to 10As shown in the figure, an embodiment of the present invention provides an intelligent building valve that prevents scaling and jamming, including a valve body 1, a valve ball 3, and two end shells 2. Two valve seats 4 are symmetrically arranged at both ends inside the valve body 1. The intelligent building valve further includes: two descaling rings 6 arranged concentrically with the valve seats 4 (as Figure 9 shown), a plurality of scraping strips 9 arranged in a circular pattern are provided on one side of each of the two descaling rings 6. The scraping strips 9 are all made of rubber components. The two descaling rings 6 are respectively rotatably connected to the inner sides of the two end shells 2 through rotating cylinders 5; a plurality of knocking mechanisms for shattering water scale are provided between the rotating cylinder 5 and the descaling ring 6 at the same end; the intelligent building valve further includes a linkage mechanism for driving the valve ball 3 and the two descaling rings 6 to rotate synchronously; the linkage mechanism includes a valve ball shaft 205 fixed to the upper end of the valve ball 3, and two gear shafts 203 that are drivingly connected to the two rotating cylinders 5 through a transmission structure. One end of each of the two gear shafts 203 is connected with a bevel gear one 204 through a clutch mechanism. A bevel gear two 206 meshing with the two bevel gears one 204 is fixed to the outside of the valve ball shaft 205. The transmission structure includes a gear one 201 fixed to the outside of the rotating cylinder 5 and a gear two 202 fixed to one end of the gear shaft 203. The gear one 201 and the gear two 202 are meshed through teeth; the knocking mechanism includes an inner cylinder 101 arranged inside the descaling ring 6 and a sliding cylinder 103 slidably arranged inside the rotating cylinder 5. A plurality of striker pins 102 are inserted into one end of the inner cylinder 101. A striker rod 104 for striking the striker pins 102 is fixed to one end of the sliding cylinder 103. The other end of the sliding cylinder 103 is elastically connected to the inside of the rotating cylinder 5 through a spring 105. The intelligent building valve further includes a compression and release mechanism for compressing and rebounding the spring 105;

[0035] When the valve ball shaft 205 is rotated to open and close the valve, the valve ball shaft 205 drives the valve ball 3 to rotate. At the same time, the two descaling rings 6 can be driven to rotate synchronously through the linkage mechanism. A plurality of scraping strips 9 are provided on one side of each descaling ring 6. Therefore, when the descaling ring 6 rotates, it will drive the plurality of scraping strips 9 on one side of it to slide along the outside of the valve ball 3, scraping off the water scale adhering to the outside of the valve ball 3. Since the valve ball 3 is also rotating at the same time, each position on the outside of the valve ball 3 can come into contact with the scraping strips 9. Therefore, the plurality of scraping strips 9 can scrape off the water scale at each position on the outside of the valve ball 3, cleaning the water scale on the surface of the valve ball 3 while opening and closing the valve, so that the water scale inside the valve can be cleaned without disassembling the valve, thereby avoiding the valve from jamming due to water scale accumulation.

[0036] Further, the compression and release mechanism includes a rotating shaft 106 rotatably inserted inside the rotating cylinder 5 and a sliding pin 107 rotatably inserted inside the sliding cylinder 103. One end of the rotating shaft 106 is fixed with a cylinder 116, and a plurality of guiding blocks 108 arranged in a circular pattern are fixed on the outer side of the cylinder 116. An inclined pushing surface 109 in contact with the sliding pin 107 is arranged on one side of each guiding block 108. A toothed ring 110 is also fixed on the inner side of the end shell 2. One end of each rotating shaft 106 is connected with a pinion 111 meshing with the toothed ring 110 through a one-way bearing. A retaining ring 112 is fixed at one end of each of the plurality of firing pins 102, and one end of each of the plurality of firing pins 102 is elastically connected to the inner side end of the inner cylinder 101 through a plurality of rubber sleeves 113. The lengths of the plurality of firing pins 102 are not equal, and the other ends of the plurality of firing pins 102 are adapted to the outer side of the valve ball 3;

[0037] Through the compression and release mechanism, the spring 105 in the knocking mechanism can be continuously compressed and then released, so as to transfer the elastic force of the spring 105 to the striker 104, causing the striker 104 to impact the plurality of firing pins 102. The plurality of firing pins 102 strike the outer surface of the valve ball 3, and the scale with a certain thickness adhering to the outer surface of the valve ball 3 can be broken, so that the scale is broken into a large number of flakes, and at the same time, the adhesion between the scale and the surface of the valve ball 3 is reduced. Therefore, when the plurality of scraping strips 9 slide along the outer surface of the valve ball 3, the scale can be more fully scraped off, improving the scale cleaning effect and further avoiding the occurrence of valve jamming problems.

[0038] Further, a dispersion plate 114 is slidably arranged inside the inner cylinder 101, and a sealing ring 115 is arranged on the outer side of the dispersion plate 114;

[0039] The striker 104 in the knocking mechanism first transfers the impact force to the dispersion plate 114, and the dispersion plate 114 can evenly transfer the impact force to one end of the plurality of firing pins 102, so that each firing pin 102 evenly strikes the surface of the valve ball 3, and the scale on the surface of the valve ball 3 can be evenly broken and fall off.

[0040] Further, the clutch mechanism includes a first spline shaft 208 fixed at one end of the bevel gear one 204 and a second spline shaft 207 fixed at one end of the gear shaft 203. The second spline shaft 207 and the first spline shaft 208 are rotatably connected, and a spline sleeve 209 is movably arranged on the outer sides of the second spline shaft 207 and the first spline shaft 208;

[0041] When cleaning, it is not necessary to disassemble the entire valve. Slide the two spline sleeves 209 of the two clutch mechanisms so that the two spline sleeves 209 are respectively and simultaneously sleeved on the outer sides of the second spline shaft 207 and the first spline shaft 208 at the same end, so that the second spline shaft 207 and the first spline shaft 208 at the same end can be combined. At this time, the first spline shaft 208 can transmit the torsional moment to the second spline shaft 207. At this time, when the valve ball 3 rotates, the two descaling rings 6 can be driven to rotate synchronously through the linkage mechanism. During the process of opening and closing the valve, the descaling ring 6 is driven to rotate, so as to scrape the water scale on the surface of the valve ball 3.

[0042] Furthermore, an annular groove 7 for accommodating the valve seat 4 is provided at one end of the inner side of each of the two end shells 2 (as Figure 7 shown), and a disc spring 8 for applying a tightening force to the valve seat 4 is provided on the inner side of each of the two annular grooves 7;

[0043] The disc spring 8 can apply a certain thrust to the valve seat 4, so that one end of the valve seat 4 is closely attached to the outer surface of the valve ball 3, improving the sealing effect between the valve ball 3 and the valve body 1 and preventing the water scale on the surface of the valve ball 3 from entering the gap between the valve ball 3 and the valve body 1 to cause jamming.

[0044] Furthermore, the two end shells 2 are both fixed to the two ends of the valve body 1 by bolts, and the valve ball 3 is rotatably connected to the inner side of the valve body 1 through the valve ball shaft 205 at its upper end;

[0045] It is convenient to disassemble the end shell 2 and the valve body 1. If there is too much water scale on the surface of the valve ball 3, resulting in the complete jamming of the valve, the internal valve ball 3 can be quickly disassembled, reducing the difficulty of disassembling and cleaning the valve.

[0046] Working principle: When normally opening and closing the valve, rotate the turntable at the top of the valve ball shaft 205 to drive the valve ball shaft 205 to rotate, and the valve ball shaft 205 drives the valve ball 3 to rotate, so as to realize the opening and closing operation of the valve. If there are many impurities such as water scale in the pipeline water, it is necessary to regularly maintain and clean the valve. When cleaning, it is not necessary to disassemble the entire valve. Slide the two spline sleeves 209 of the two clutch mechanisms so that the two spline sleeves 209 are respectively and simultaneously sleeved on the outer sides of the second spline shaft 207 and the first spline shaft 208 at the same end, so that the second spline shaft 207 and the first spline shaft 208 at the same end can be combined. At this time, the first spline shaft 208 can transmit the torsional moment to the second spline shaft 207;

[0047] When rotating the valve ball shaft 205 to open and close the valve, the valve ball shaft 205 drives the bevel gear two 206 on its outer side to rotate. The bevel gear two 206 drives the two bevel gears one 204 to rotate through tooth engagement. The two bevel gears one 204 respectively drive the two first spline shafts 208 to rotate. The two first spline shafts 208 respectively drive the two second spline shafts 207 to rotate through the two spline sleeves 209. The two second spline shafts 207 respectively drive the two gear shafts 203 to rotate. The two gear shafts 203 drive the two gears two 202 to rotate. The two gears two 202 drive the two gears one 201 to rotate through tooth engagement. The two gears one 201 respectively drive the two rotating cylinders 5 to rotate. Since one end of the rotating cylinder 5 is fixedly connected to the descaling ring 6, the two rotating cylinders 5 respectively drive the two descaling rings 6. Since a plurality of scraping bars 9 are arranged on one side of the descaling ring 6, when the descaling ring 6 rotates, it will drive the plurality of scraping bars 9 on its one side to slide along the outer side of the valve ball 3, scraping off the water scale adhering to the outer side of the valve ball 3. At the same time, when the valve ball shaft 205 drives the valve ball 3 to rotate to open and close, the valve ball 3 also rotates simultaneously, so that all positions on the outer side of the valve ball 3 can contact the scraping bars 9. Therefore, the plurality of scraping bars 9 can scrape off the water scale at all positions on the outer side of the valve ball 3, cleaning the water scale on the surface of the valve ball 3 while opening and closing the valve, so that the water scale inside the valve can be cleaned without disassembling the valve, thus avoiding the valve opening and closing jamming caused by water scale accumulation;

[0048] It should be noted that when the bevel gear two 206 drives the two bevel gears one 204 to rotate, the two bevel gears one 204 rotate in opposite directions. Therefore, the two rotating cylinders 5 and the descaling rings 6 are driven to rotate in opposite directions. Therefore, the two one-way bearings need to be installed in the opposite direction;

[0049] In order to facilitate the shedding of scale covering the surface of the valve ball 3 over a large area, multiple knocking mechanisms are provided. While the linkage mechanism drives the rotating cylinder 5 and the descaling ring 6 to rotate, the rotating cylinder 5 and the descaling ring 6 will drive components such as the inner cylinder 101, the sliding cylinder 103, and the rotating shaft 106 in the knocking mechanism to rotate synchronously. When the rotating shaft 106 in the compression release mechanism rotates with the rotating cylinder 5, it will drive the small gear 111 at its end to rotate around the toothed ring 110. Through the tooth engagement between the small gear 111 and the toothed ring 110, when the small gear 111 rotates around the toothed ring 110, it can generate self-rotation. When the rotating shaft 106 rotates, it drives the cylinder 116 at its end to rotate, and the cylinder 116 drives multiple guiding blocks 108 on its outer side to rotate. Since the sliding pin 107 inside the sliding cylinder 103 fits on the inclined pushing surface 109 of one side of the guiding block 108, when the cylinder 116 drives the guiding block 108 to rotate in one direction, under the pushing action of the inclined pushing surface 109, a thrust in the same direction as the length direction of the rotating shaft 106 can be applied to the sliding pin 107, so that the sliding cylinder 103 moves towards one end and compresses the spring 105, storing energy in the spring 105. When the sliding pin 107 separates from the top of the inclined pushing surface 109, the sliding pin 107 loses the support of the guiding block 108. At this time, the spring 105 quickly releases its elastic force, pushing the sliding cylinder 103 to move rapidly in the reverse direction. The sliding cylinder 103 drives the impact rod 104 to move rapidly towards the inside of the inner cylinder 101. Since the impact rod 104 is slidably inserted into the inside of the rotating cylinder 5 through spline fitting, the impact rod 104 and the sliding cylinder 103 will not rotate but only move linearly. When the impact rod 104 rapidly impacts the dispersion plate 114, the dispersion plate 114 evenly transmits the impact force to one end of the retaining ring 112 at one end of multiple impact needles 102, so that multiple impact needles 102 can extend a certain distance outside the descaling ring 6 and impact the outer surface of the valve ball 3. Under the action of the elastic rubber sleeve 113, when multiple impact needles 102 impact the valve ball 3, they can quickly reset. As the rotating shaft 106 continuously rotates following the rotating cylinder 5 and can maintain self-rotation, it can drive the sliding cylinder 103 and the impact rod 104 of the knocking mechanism to continuously knock the dispersion plate 114, thereby knocking multiple impact needles 102. Multiple impact needles 102 impact the outer surface of the valve ball 3, which can break the scale adhering to the outer surface of the valve ball 3 and having a certain thickness, making the scale break into a large number of flakes, and at the same time reducing the adhesion between the scale and the surface of the valve ball 3. Therefore, when multiple scraping strips 9 slide along the outer surface of the valve ball 3, the scale can be more fully scraped off, improving the scale cleaning effect and further avoiding the occurrence of valve jamming problems;

[0050] It should be noted that since the two rotating cylinders 5 and the two descaling rings 6 rotate in opposite directions, the inclined pushing surfaces 109 located outside the two cylinders 116 are also arranged in opposite directions (as Figure 10 shown);

[0051] When the valve ball 3 rotates reversely, it will drive the rotating cylinder 5 to rotate reversely. Since one end of each rotating shaft 106 is connected with a pinion 111 through a one-way bearing, the reverse self-rotation of the pinion 111 at this time will not drive the rotating shaft 106 to rotate reversely, preventing the vertical surface of the guiding block 108 from abutting against the sliding pin 107;

[0052] The disc spring 8 can apply a certain thrust to the valve seat 4, so that one end of the valve seat 4 is closely attached to the outer surface of the valve ball 3, improving the sealing effect between the valve ball 3 and the valve body 1 and preventing the water scale on the surface of the valve ball 3 from entering the gap between the valve ball 3 and the valve body 1 to cause jamming;

[0053] The striker 104 in the knocking mechanism first transmits the impact force to the dispersion plate 114. The dispersion plate 114 can evenly transmit the impact force to one end of a plurality of firing pins 102, so that each firing pin 102 evenly knocks the surface of the valve ball 3, and the water scale on the surface of the valve ball 3 can be evenly broken and shed.

[0054] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
