Description

Technical Field

[0001] The present invention relates to the field of valve technology, and in particular to an intelligent building valve capable of preventing scaling and jamming. Background Art

[0002] The building ball valve is a key control device installed on the water supply main of residential buildings or commercial buildings. It is mainly used to open and close water flow, adjust flow or isolate pipeline sections for maintenance. Its core component is a sphere with a through hole, which can be quickly switched on and off by rotating 90 degrees.

[0003] After searching, a Chinese patent with publication number: CN220185881U discloses an anti-fouling ball valve, including a sphere with a through diameter, the sphere is placed in the inner cavity of the valve body, the valve body is an integrally formed seamless structure, the upper part of the valve body is provided with a mounting opening, the valve cover is connected to the mounting 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 sealed and anti-fouling structure for the upper and lower surfaces of the sphere.

[0004] Based on the above search and combined with actual problems, it was found that: although the 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 applications, most of the surface area of ​​the valve ball will directly contact the water in the pipeline. When the surface of the valve ball is covered with a layer of scale, the 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, thereby further increasing the rotation resistance of the valve ball, which can easily cause the ball valve to get stuck.

[0021] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. 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.

[0022] The present invention provides an intelligent building valve that prevents scaling and jamming through improvement. The technical solution of the present invention is: like Figures 1 to 10 As shown, the embodiment of the present invention provides an anti-scaling and anti-jamming intelligent building valve, including a valve body 1, a valve ball 3 and two end shells 2, two valve seats 4 are symmetrically arranged at both ends of the inner side of the valve body 1, and also includes: two descaling rings 6 (such as Fig. 9As shown in the figure, one side of the two descaling rings 6 is provided with a plurality of scraping strips 9 arranged in a circumference, and the scraping strips 9 are made of rubber. The two descaling rings 6 are respectively connected to the inner sides of the two end shells 2 through the rotating drum 5; a plurality of knocking mechanisms for crushing scale are provided between the rotating drum 5 and the descaling ring 6 at the same end; and a linkage mechanism is also included to drive 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, two gear shafts 203 connected to the two rotating drums 5 through a transmission structure, one end of the two gear shafts 203 is connected to a bevel gear 204 through a clutch mechanism, and the outer side of the valve ball shaft 205 is fixed with The bevel gear 206 meshes with the two bevel gears 1 204, and the transmission structure includes a gear 1 201 fixed to the outside of the rotating drum 5 and a gear 202 fixed to one end of the gear shaft 203, and the gear 1 201 and the gear 2 202 are meshed through teeth; the knocking mechanism includes an inner cylinder 101 arranged inside the descaling ring 6 and a slide cylinder 103 slidably arranged inside the rotating drum 5, a plurality of strikers 102 are inserted at one end of the inner cylinder 101, a striker rod 104 for striking the striker 102 is fixed at one end of the slide cylinder 103, and the other end of the slide cylinder 103 is elastically connected to the inside of the rotating drum 5 through a spring 105, and also includes a compression release mechanism for compressing and rebounding the spring 105; 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, and 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 arranged on one side of each descaling ring 6. Therefore, when the descaling ring 6 rotates, it drives the plurality of scraping strips 9 on one side thereof to slide along the outer side of the valve ball 3, and scrapes off the scale adhered to the outer side of the valve ball 3. Since the valve ball 3 is also rotating at the same time, each position of the outer side of the valve ball 3 can contact the scraping strip 9. Therefore, the plurality of scraping strips 9 can scrape off the scale at each position of the outer side of the valve ball 3, and clean the scale on the surface of the valve ball 3 while opening and closing the valve, so that the scale inside the valve can be cleaned without disassembling the valve, thereby avoiding the valve opening and closing jamming caused by scale accumulation.

[0023] Furthermore, the compression release mechanism includes a rotating shaft 106 rotatably inserted inside the rotating cylinder 5, a sliding pin 107 rotatably inserted inside the sliding cylinder 103, a cylinder 116 is fixed at one end of the rotating shaft 106, and a plurality of guide blocks 108 arranged in a circumference are fixed on the outer side of the cylinder 116, and a side of each guide block 108 is provided with an inclined push surface 109 in contact with the sliding pin 107, and a gear ring 110 is also fixed to the inner side of the end shell 2, and one end of each rotating shaft 106 is connected to a pinion 111 meshing with the gear ring 110 through a one-way bearing, and a retaining ring 112 is fixed at one end of the plurality of strikers 102, and one end of the plurality of strikers 102 is elastically connected to one end of the inner side of the inner cylinder 101 through a plurality of rubber sleeves 113, and the lengths of the plurality of strikers 102 are unequal, and the other ends of the plurality of strikers 102 are adapted to the outer side of the valve ball 3; Through the compression release mechanism, the spring 105 in the knocking mechanism can be continuously compressed and then released, so that the elastic force of the spring 105 is transmitted to the impact rod 104, so that the impact rod 104 impacts the multiple strikers 102, and the multiple strikers 102 knock on the outer surface of the valve ball 3, which can break the scale with a certain thickness adhering to the outer surface of the valve ball 3, and break the scale into a large number of flakes, while reducing the adhesion between the scale and the surface of the valve ball 3. Therefore, when the multiple scraping strips 9 slide along the outer surface of the valve ball 3, the scale can be scraped off more fully, thereby improving the scale cleaning effect and further avoiding the problem of valve jamming.

[0024] Furthermore, a dispersion plate 114 is slidably disposed on the inner side of the inner cylinder 101, and a sealing ring 115 is disposed on the outer side of the dispersion plate 114; The impact rod 104 in the knocking mechanism first transmits the impact force to the dispersion plate 114, and the dispersion plate 114 can evenly transmit the impact force to one end of multiple strikers 102, so that each striker 102 evenly strikes the surface of the valve ball 3, so that the scale on the surface of the valve ball 3 can be evenly broken and fallen off.

[0025] Further, the clutch mechanism includes a first spline shaft 208 fixed to one end of the bevel gear 204, a second spline shaft 207 fixed to 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 provided on the outer sides of the second spline shaft 207 and the first spline shaft 208; When cleaning, there is no need 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 outside 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 torsional torque 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, so that the descaling ring 6 is driven to rotate during the opening and closing of the valve, thereby scraping off the scale on the surface of the valve ball 3.

[0026] Furthermore, an annular groove 7 (such as Figure 7 As shown), disc springs 8 are provided on the inner sides of the two annular grooves 7 to apply a pushing force to the valve seat 4; The disc spring 8 can apply a certain thrust to the valve seat 4, so that one end of the valve seat 4 fits tightly against the outer surface of the valve ball 3, thereby improving the sealing effect between the valve ball 3 and the valve body 1 and preventing scale on the surface of the valve ball 3 from entering the gap between the valve ball 3 and the valve body 1 and causing jamming.

[0027] Furthermore, the two end shells 2 are 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; It is convenient to disassemble the end shell 2 and the valve body 1. If there is too much scale on the surface of the valve ball 3, causing the valve to be completely stuck, the internal valve ball 3 can be quickly disassembled, reducing the difficulty of disassembling and cleaning the valve.

[0028] Working principle: When opening and closing the valve normally, the turntable at the top of the valve ball shaft 205 is rotated to drive the valve ball shaft 205 to rotate, and the valve ball shaft 205 drives the valve ball 3 to rotate, thereby realizing the opening and closing operation of the valve. If there are a lot of impurities such as scale in the water in the pipeline, the valve needs to be regularly maintained and cleaned. When cleaning, there is no need 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 torsional torque to the second spline shaft 207; When the valve ball shaft 205 is rotated to open and close the valve, the valve ball shaft 205 drives the outer bevel gear 2 206 to rotate, and the bevel gear 2 206 drives the two bevel gears 1 204 to rotate through tooth meshing, and the two bevel gears 1 204 respectively drive the two first spline shafts 208 to rotate, and the two first spline shafts 208 respectively drive the two second spline shafts 207 to rotate through the two spline sleeves 209, and the two second spline shafts 207 respectively drive the two gear shafts 203 to rotate, and the two gear shafts 203 drive the two gears 202 to rotate, and the two gears 202 drive the two gears 1 201 to rotate through tooth meshing, and the two gears 1 201 respectively drive the two rotating drums 5 to rotate. Since one end of the rotating drum 5 is fixedly connected to the descaling ring 6 Therefore, the two rotating drums 5 drive two descaling rings 6 respectively. Since a plurality of scraping strips 9 are arranged on one side of the descaling ring 6, when the descaling ring 6 rotates, it drives the plurality of scraping strips 9 on one side thereof to slide along the outer side of the valve ball 3, and scrapes off the 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 realize opening and closing, the valve ball 3 also rotates at the same time, so that each position of the outer side of the valve ball 3 can contact the scraping strips 9. Therefore, the plurality of scraping strips 9 can scrape off the scale at each position of the outer side of the valve ball 3, and clean the scale on the surface of the valve ball 3 while opening and closing the valve, so that the scale inside the valve can be cleaned without disassembling the valve, thereby avoiding the valve opening and closing jamming caused by scale accumulation; It should be noted that when the bevel gear 206 drives the two bevel gears 1 204 to rotate, the two bevel gears 1 204 rotate in the opposite direction, thereby driving the two rotating drums 5 and the descaling ring 6 to rotate in the opposite direction, so the two one-way bearings need to be installed in the opposite direction; In order to facilitate the removal of scale covering a large area on the surface of the valve ball 3, multiple knocking mechanisms are provided. When the linkage mechanism drives the rotating drum 5 and the descaling ring 6 to rotate, the rotating drum 5 and the descaling ring 6 will drive the inner drum 101, the sliding drum 103, the rotating shaft 106 and other components in the knocking mechanism to rotate synchronously. When the rotating shaft 106 in the compression release mechanism rotates with the rotating drum 5, it will drive the pinion 111 at the end to rotate around the gear ring 110. Through the meshing of the teeth between the pinion 111 and the gear ring 110, the pinion 111 can generate self-rotation while rotating around the gear ring 110. When the rotating shaft 106 rotates, it drives the column 116 at its end to rotate. 116 drives multiple guide blocks 108 on the outside thereof to rotate. Since the sliding pin 107 on the inside of the slide cylinder 103 is attached to the surface of the inclined push surface 109 on one side of the guide block 108, when the column 116 drives the guide block 108 to rotate in one direction, under the pushing action of the inclined push surface 109, the sliding pin 107 can apply a thrust in the same direction as the length of the rotating shaft 106, so that the slide cylinder 103 moves to one end and compresses the spring 105, so that the spring 105 accumulates force. When the sliding pin 107 separates from the top of the inclined push surface 109, the sliding pin 107 loses the support of the guide block 108. At this time, the spring 105 quickly releases its elastic force, pushing the slide cylinder 103 to reverse The slide cylinder 103 drives the striker 104 to move quickly toward the inner side of the inner cylinder 101. Since the striker 104 is slidably inserted into the inner side of the rotating cylinder 5 through a spline fit, the striker 104 and the slide cylinder 103 will not rotate but will only move in a straight line. When the striker 104 quickly hits 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 the multiple strikers 102, so that the multiple strikers 102 can extend a certain distance outside the descaling ring 6 and hit the outer surface of the valve ball 3. Under the action of the elastic rubber sleeve 113, the multiple strikers 102 can be quickly reset after hitting the valve ball 3. As the rotating shaft 106 rotates continuously with the rotating drum 5, it can keep rotating by itself, so as to drive the sliding drum 103 and the striking rod 104 of the striking mechanism to continuously strike the dispersion plate 114, thereby striking the multiple striking pins 102. The multiple striking pins 102 strike the outer surface of the valve ball 3, which can break the scale with a certain thickness adhering to the outer surface of the valve ball 3, 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 multiple scraping strips 9 slide along the outer surface of the valve ball 3, the scale can be scraped off more fully, thereby improving the scale cleaning effect and further avoiding the problem of valve jamming; It should be noted that, since the two drums 5 and the two descaling rings 6 rotate in opposite directions, the inclined push surfaces 109 located outside the two cylinders 116 are also arranged in opposite directions (such as Fig.10 shown); When the valve ball 3 rotates in the reverse direction, the drum 5 will be driven to rotate in the reverse direction. Since one end of each rotating shaft 106 is connected to a pinion 111 through a one-way bearing, the reverse rotation of the pinion 111 will not drive the rotating shaft 106 to rotate in the reverse direction, thereby preventing the vertical surface of the guide block 108 from abutting against the sliding pin 107. 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 fitted with the outer surface of the valve ball 3, thereby improving the sealing effect between the valve ball 3 and the valve body 1, and preventing 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; The impact rod 104 in the knocking mechanism first transmits the impact force to the dispersion plate 114, and the dispersion plate 114 can evenly transmit the impact force to one end of multiple strikers 102, so that each striker 102 evenly strikes the surface of the valve ball 3, so that the scale on the surface of the valve ball 3 can be evenly broken and fallen off.

[0029] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may 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 the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
