Description

Technical Field

[0001] The present invention relates to the technical field of high-platform flange ball valves, and particularly relates to an integrated high-platform flange ball valve and a using method thereof. Background Art

[0002] A high-platform flange ball valve is a valve widely used in pipeline systems to control fluid flow. Its design aims to provide high-performance sealing and flow control, and is applied in the oil and gas industry (for on-off control of oil and gas transmission pipelines), the chemical industry (to control the flow of various chemical media), water treatment (used in sewage treatment and water purification systems), air conditioning and refrigeration (to control the fluid flow in refrigeration systems), and the power industry (applied in the steam control system of power plants).

[0003] In a high-platform flange ball valve, a gap may form between the ball and the valve body for certain reasons, resulting in fluid leakage. For example, long-term use causes wear of the sealing surfaces of the ball and the valve body, aging of the sealing material, loss of elasticity and sealing ability, and accumulation of solid particles or impurities in the medium in the sealing area. Once a gap appears between the ball and the valve body, it will directly cause the ball valve to leak water, and immediate maintenance is required. It cannot automatically block the water leakage position between the ball and the valve body, and cannot automatically adjust the sealing effect when water leaks at this position to extend the normal service life of the ball valve. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated high-platform flange ball valve and a using method thereof, which solve the problem that in a traditional high-platform flange ball valve, once a gap forms between the ball and the valve body, resulting in fluid leakage, it will directly cause the ball valve to leak water, immediate maintenance is required, it cannot automatically block the water leakage position between the ball and the valve body, and cannot automatically adjust the sealing effect when water leaks at this position to extend the normal service life of the ball valve.

The lower leakage prevention part is arranged inside the lower accommodation groove and is used for automatically blocking and preventing leakage of the lower half between the sphere and the valve body. The side leakage prevention parts are arranged at both ends of the valve body, and the side leakage prevention parts are used for automatically improving the sealing performance of the joints at both ends of the valve body.

[0006] Preferably, two first annular clamping grooves are opened inside the upper accommodation groove. The upper leakage prevention part includes two first annular support bars fixed inside the upper accommodation groove and a first floating plate sliding inside the upper accommodation groove. Two first clamping bars and a first leakage prevention strip are fixed above the first floating plate.

[0007] Preferably, two second annular clamping grooves are opened inside the lower accommodation groove. The lower leakage prevention part includes two second annular support bars fixed inside the lower accommodation groove and a second floating plate sliding inside the lower accommodation groove. Two second clamping bars and a second leakage prevention strip are fixed above the second floating plate. An inner groove is opened above the second leakage prevention strip, and a plurality of water inlet grooves are opened inside the inner groove.

[0008] Preferably, two side through water grooves are opened below the first floating plate and below the second floating plate. Inner grooves are opened inside the two first clamping bars and the two second clamping bars. The four inner grooves are respectively communicated with the four side through water grooves through holes. The four inner grooves are all filled with a first filler. Main through water grooves are opened below the first floating plate and the second floating plate. Main grooves are opened inside the first leakage prevention strip and the second leakage prevention strip. The two main through water grooves are respectively communicated with the two main grooves through water holes. The two main grooves are all filled with a second filler.

[0009] Preferably, two annular installation grooves are opened on the outer surface of the sphere. Diversion channels are opened inside the two annular installation grooves. Annular sealing grooves are opened on the inner surface of the valve body. The main leakage prevention part includes annular concave strip sealing rings respectively fixed inside the two annular sealing grooves, hollow main sealing strips respectively arranged inside the two annular installation grooves, and porous annular frames respectively arranged inside the two annular installation grooves. A plurality of springs are fixed on one side of each of the two porous annular frames. The four fillers are filled inside the two hollow main sealing strips.

[0010] Preferably, sealing grooves are provided at both ends of the valve body. First water diversion grooves and second water diversion grooves are provided at both ends of the valve body. Annular through grooves are provided inside the two first water diversion grooves and the two second water diversion grooves. The side leakage prevention member includes sealing rings respectively arranged inside the two sealing grooves. A plurality of annular ridges are provided on one side of one of the sealing rings, and a plurality of annular grooves are provided on one side of the other sealing ring.

[0011] Preferably, packing grooves are provided inside the two sealing rings. Third packing materials are filled inside the two packing grooves. Two porous strip grooves are provided inside the two sealing rings. The first packing material, the second packing material, the third packing material, and the fourth packing material are all water-absorbing and swelling rubbers.

[0012] A using method of an integrated high-platform flange ball valve includes the following steps: Step 1: When the ball valve is closed, the hollow main sealing strip will correspond to the annular concave strip sealing ring. If there is a sealing problem between the ball and the valve body in the later stage, the hollow main sealing strip and the annular concave strip sealing ring will play an anti-leakage effect for a period of time. Step 2: Furthermore, after leakage occurs between the ball and the valve body in the later stage, the water source will enter the upper accommodation groove and the lower accommodation groove along the upper annular groove and the lower annular groove respectively. Subsequently, the first floating plate and the second floating plate will rise. The first leakage prevention strip will be inserted into the upper sealing groove, and the second leakage prevention strip will be inserted into the lower sealing groove to intercept the local water source leaking from the outside of the ball, realizing automatic sealing, reducing the penetration amount of the water source. The first leakage prevention strip can also increase the sealing performance at the positions of the ball and the valve stem, avoiding water leakage of the valve stem. Step 3: The water source in the upper annular groove enters the annular installation groove through the diversion channel. After contacting the fourth packing material, the hollow main sealing strip will expand passively. When the ball valve is closed in the later stage, the hollow main sealing strip can fully seal the gap between the ball and the annular concave strip sealing ring on the inner wall of the valve body, thereby automatically repairing the water leakage phenomenon of the ball valve, effectively increasing the normal service duration of the ball valve, and automatically adjusting and improving the sealing effect when water leakage occurs during the closing period of the ball valve. Step 4: When the original sealing layer at the flange connection of both ends of the valve body fails and is damaged, the water source will seep into the first water diversion groove and the second water diversion groove. The water source contacts the third packing material through the porous strip groove and causes it to expand, thereby filling the sealing ring, enabling the sealing ring to fully fill the gap after the sealing member fails, improving the sealing effect, realizing automatic repair and sealing of the water leakage position, and increasing the effective service duration of the sealing at both ends of the ball valve.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. After leakage occurs between the water source and the valve body on the sphere, it will enter the upper receiving groove along the upper annular groove, and then enter the annular installation groove through the diversion channel to expand the fourth packing, so as to expand the hollow main sealing strip. Later, when the ball valve is closed, the hollow main sealing strip can fully seal the gap between the sphere and the inner wall of the valve body, thereby automatically repairing the water leakage phenomenon of the ball valve, effectively extending the normal service life of the ball valve, and automatically adjusting and improving the sealing effect when water leakage occurs during the closing period of the ball valve.

[0015] 2. After the upper receiving groove is filled with water, the first floating plate rises until the first leak-proof strip is inserted into the upper sealing groove, increasing the sealing performance at the connection position between the sphere and the valve stem. When the ball valve is in the open state, if water leakage occurs between the sphere and the valve body, it can automatically seal the position around the valve stem to prevent water leakage at the valve stem.

[0016] 3. When water leaks at the flange connection at both ends of the valve body, the water source will seep into the first water guide groove and the second water guide groove. After the water source contacts the third packing and causes it to expand, the sealing ring will be filled, so that the sealing ring fully fills the gap after the seal fails, improving the sealing effect, achieving automatic repair and sealing of the water leakage position, and extending the effective service life of the seal at both ends of the ball valve.

[0019] The following further elaborates on the above and other technical features and advantages of the present invention with reference to the accompanying drawings.

[0020] The present invention provides a technical solution: an integrated high-platform flange ball valve, as Figures 1 - 9 shown, including a valve body 1 and a leakage prevention assembly 9 disposed inside the valve body 1. Flanges are fixed at both ends of the valve body 1. A valve cover is connected above the valve body 1. A valve stem is disposed inside the valve cover. The valve stem is used to connect the sphere 2 and the operating mechanism (such as a handwheel, gear, or electric device) of the ball valve to control the rotation of the sphere 2. When the valve stem rotates, the sphere 2 rotates accordingly, thereby realizing the opening and closing of the valve. A sealing packing is disposed inside the valve cover. The sealing packing is used to seal the space between the valve stem and the valve cover to prevent fluid leakage. The valve cover is commonly used to support the valve stem and the sealing packing. The sphere 2 is installed inside the valve body 1. An upper annular groove 3, an upper receiving groove 4, and a lower sealing groove 5 are opened inside the sphere 2. The upper annular groove 3 communicates with the upper receiving groove 4. A plurality of first connecting bodies 20 are connected between the upper annular groove 3 and the upper receiving groove 4. The plurality of first connecting bodies 20 are arranged in a ring in sequence between the upper annular groove 3 and the upper receiving groove 4 to prevent the sphere 2 from being separated by the upper annular groove 3 and the upper receiving groove 4. The upper annular groove 3 is used to introduce the water source that seeps into the gap between the sphere 2 and the valve body 1 into the upper receiving groove 4.

[0021] As Figures 1 - 9As shown in the figure, the inner surface of the valve body 1 is provided with a lower annular groove 6, a lower receiving groove 7 and an upper sealing groove 8. The lower annular groove 6 is communicated with the lower receiving groove 7. A plurality of second connecting bodies 16 are connected between the lower annular groove 6 and the lower receiving groove 7. The plurality of second connecting bodies 16 are arranged in a ring between the lower annular groove 6 and the lower receiving groove 7 in sequence, so as to prevent the sphere 2 from being separated by the lower annular groove 6 and the lower receiving groove 7. The lower annular groove 6 is used to introduce the water source seeping into the gap between the sphere 2 and the valve body 1 into the lower receiving groove 7. Two first annular clamping grooves 10 are provided inside the upper receiving groove 4. Two second annular clamping grooves 11 are provided inside the lower receiving groove 7. Sealing clamping grooves 12 are provided at both ends of the valve body 1. First water guide grooves 13 and second water guide grooves 14 are provided at equal intervals at both ends of the valve body 1. Annular through grooves 15 for seeping the water source into the inside of the sealing clamping groove 12 are provided inside the two first water guide grooves 13 and the two second water guide grooves 14. Two annular mounting grooves 17 are provided on the outer surface of the sphere 2. Shunt channels 18 communicated with the upper annular groove 3 are provided inside the two annular mounting grooves 17. Two annular plugging grooves 19 with the same diameter size as the annular mounting grooves 17 and opposite positions are provided on the inner surface of the valve body 1.

[0022] As Figures 1 - 9 shown, the leak-proof assembly 9 includes an upper leak-proof member and a lower leak-proof member. The upper leak-proof member is arranged inside the upper receiving groove 4 and is used to automatically plug and prevent leakage of the upper half between the sphere 2 and the valve body 1, so as to increase the sealing performance of the connection position between the upper half of the sphere 2, the valve body 1 and the valve stem. When the water source penetrates to the upper part of the sphere 2, automatic plugging can be realized, part of the penetrated water source can be intercepted, the amount of water source penetration and the possibility of valve stem water leakage can be reduced. The lower leak-proof member is arranged inside the lower receiving groove 7 and is used to automatically plug and prevent leakage of the lower half between the sphere 2 and the valve body 1, so as to increase the sealing performance of the connection position between the lower half of the sphere 2 and the valve body 1. When the water source penetrates to the lower part of the sphere 2, automatic plugging can be realized, part of the penetrated water source can be intercepted, and the amount of water source penetration can be reduced. There is a double insurance in the overall sealing of the ball valve. The upper leak-proof member includes two first annular support bars 91 fixed inside the upper receiving groove 4 and a first floating plate 92 sliding inside the upper receiving groove 4. Two first clamping bars 93 adapted to the first annular clamping grooves 10 in size and a first leak-proof bar 94 adapted to the upper sealing groove 8 in size are fixed above the first floating plate 92. The lower leak-proof member includes two second annular support bars 95 fixed inside the lower receiving groove 7 and a second floating plate 96 sliding inside the lower receiving groove 7. Two second clamping bars 97 adapted to the second annular clamping grooves 11 in size and a second leak-proof bar 98 adapted to the lower sealing groove 5 in size are fixed above the second floating plate 96. An inner groove 99 is provided above the second leak-proof bar 98. The shape of the lower sealing groove 5 is the same as that of the second leak-proof bar 98. A plurality of annularly arranged water inlet grooves 910 are provided inside the inner groove 99.

[0023] As Figures 1 - 9 shown, two side through-water channels 911 are provided below the first floating plate 92 and below the second floating plate 96. The positions of the side through-water channels 911 on the first floating plate 92 correspond to the first clamping strips 93, and the positions of the side through-water channels 911 on the second floating plate 96 correspond to the second clamping strips 97. Inner grooves 912 are provided inside the two first clamping strips 93 and the two second clamping strips 97. The four inner grooves 912 are respectively connected to the four side through-water channels 911 through holes. The interiors of the four inner grooves 912 are filled with first packing materials 913. The opening of the holes facilitates the water flow to contact the first packing materials 913. Main through-water channels 914 are provided below the first floating plate 92 and the second floating plate 96. The position of the main through-water channel 914 on the first floating plate 92 is correspondingly arranged below the first leak-proof strip 94, and the position of the main through-water channel 914 on the second floating plate 96 is correspondingly arranged below the second leak-proof strip 98. Main grooves 915 are provided inside the first leak-proof strip 94 and the second leak-proof strip 98. The two main through-water channels 914 are respectively connected to the two main grooves 915 through water holes. The interiors of the two main grooves 915 are filled with second packing materials 916. The opening of the water holes facilitates the water flow to contact the second packing materials 916.

[0024] As Figures 1 - 9 shown, the leak-proof assembly 9 further includes a main leak-proof member. The main leak-proof member is arranged outside the sphere 2. When the ball valve is closed, the main leak-proof member seals the channels on both sides of the valve body 1 and the gaps of the sphere 2. When the ball valve is in the closed state, it directly seals the leakage of the water source along the sphere 2 in all directions. And after water leakage occurs later, the sealing performance is automatically increased, and the sealing position is fully filled to avoid the leakage of the water source. The main leak-proof member includes annular concave-strip sealing rings 923 respectively fixed inside the two annular sealing grooves 19, hollow main sealing strips 924 respectively arranged inside the two annular installation grooves 17, and porous annular frames 925 respectively fixed inside the two annular installation grooves 17. A plurality of equally spaced springs 926 are fixed on one side of each of the two porous annular frames 925. Fourth packing materials 927 are filled inside the two hollow main sealing strips 924.

[0025] When the ball valve is closed, the position on the sphere 2 where the hollow main sealing strip 924 is installed will correspond to the annular concave strip sealing ring 923. When the sphere 2 inside the ball valve is intact, there will be no phenomenon of water leakage from the gap between the sphere 2 and the valve body 1. At this time, the shape of the hollow main sealing strip 924 is in its original state. If there is a sealing problem between the sphere 2 and the valve body 1 later, the contact between the hollow main sealing strip 924 and the annular concave strip sealing ring 923 will play an anti-leakage effect for a period of time. Moreover, after water leaks between the sphere 2 and the valve body 1 later, it will enter the upper accommodation groove 4 and the lower accommodation groove 7 along the upper annular groove 3 and the lower annular groove 6 respectively. After the water in the upper accommodation groove 4 and the lower accommodation groove 7 gradually increases, the first floating plate 92 and the second floating plate 96 will rise until the two first clamping strips 93 are inserted into the corresponding first annular clamping grooves 10 and the second clamping strips 97 are inserted into the corresponding second annular clamping grooves 11. At this time, the first leakage prevention strip 94 will be inserted into the upper sealing groove 8 and the second leakage prevention strip 98 will be inserted into the lower sealing groove 5 to intercept the partial water leakage from the outside of the sphere 2. The second leakage prevention strip 98 in the lower accommodation groove 7 can achieve automatic sealing when water penetrates to the lower part of the sphere 2, intercepting part of the penetrated water and reducing the amount of water penetration. The first leakage prevention strip 94 in the upper accommodation groove 4 increases the sealing performance at the connection position between the upper half of the sphere 2, the valve body 1 and the valve stem. When water penetrates to the upper part of the sphere 2, it can achieve automatic sealing, intercepting part of the penetrated water and reducing the amount of water penetration and the phenomenon of valve stem water leakage. Moreover, the water in the upper annular groove 3 will enter the annular installation groove 17 through the diversion channel 18. After the water in the annular installation groove 17 contacts the fourth packing 927, the fourth packing 927 expands to fill the hollow main sealing strip 924 and make it expand. Later, when the ball valve is closed, the hollow main sealing strip 924 can fully seal the gap between the sphere 2 and the annular concave strip sealing ring 923 on the inner wall of the valve body 1, thereby automatically repairing the water leakage phenomenon of the ball valve, effectively increasing the normal service duration of the ball valve, automatically adjusting and improving the sealing effect when the ball valve leaks during the closed period. Later, when the sphere 2 is rotated, since the periphery of the hollow main sealing strip 924 is arc-shaped and has a certain elasticity, and due to the spring 926, when the sphere 2 rotates, the hollow main sealing strip 924 can be squeezed into the annular installation groove 17 and squeeze the spring 926, and the sphere 2 will not be unable to rotate due to the expansion of the hollow main sealing strip 924. Later, when the sphere 2 rotates to close the ball valve, the hollow main sealing strip 924, due to the limitation of the spring 926, its own elasticity and the relationship of being expandable, will re-seal the gap between the sphere 2 and the annular concave strip sealing ring 923.

[0026] Such as Figures 1 - 9As shown, the leakage prevention component 9 further includes side leakage prevention parts which are arranged at both ends of the valve body 1. The side leakage prevention parts are used to automatically improve the sealing performance at the joints at both ends of the valve body 1. If the sealing parts at the flange joints are aged or damaged and lose the sealing effect, and water leakage occurs at both ends of the valve body 1, the side leakage prevention parts can automatically adjust the sealing structure and effect at the leakage point, providing a double insurance design for the sealing parts at both ends of the valve body 1. The side leakage prevention parts include sealing rings 917 respectively arranged inside two sealing grooves 12. Multiple annular ridges 921 are arranged on one side of one sealing ring 917, and multiple annular grooves 922 are formed on one side of the other sealing ring 917. When the corresponding flanges are installed at both ends of the valve body 1, sealing rings corresponding to the sealing rings 917 are arranged on the corresponding flanges, and the shape of the sealing ring corresponding to the sealing ring 917 with annular ridges 921 is the same as that of the sealing ring 917 with annular grooves 922, and vice versa. The shape of the sealing ring corresponding to the sealing ring 917 with annular grooves 922 is the same as that of the sealing ring 917 with annular ridges 921. Packing grooves 918 are formed inside both sealing rings 917, and third packing 919 is filled inside both packing grooves 918. Two porous strip grooves 920 are formed inside both sealing rings 917. The first packing 913, the second packing 916, the third packing 919 and the fourth packing 927 are all water-absorbing and swelling rubbers.

[0027] When the original sealing layer at the flange joints at both ends of the valve body 1 fails and is damaged, resulting in water leakage at the flange, the water source will seep into the first water guide groove 13 and the second water guide groove 14. After the first water guide groove 13 and the second water guide groove 14 are filled with water, in the case of continuous water seepage, the excess water will contact the third packing 919 through the porous strip grooves 920. The third packing 919 swells after absorbing water, thereby filling the sealing ring 917, enabling the sealing ring 917 to fully fill the gap after the sealing part fails, improving the sealing effect, realizing the automatic repair and sealing of the water leakage position, and increasing the effective service life of the sealing at both ends of the ball valve.

[0028] A usage method of an integrated high-platform flange ball valve includes the following steps: Step 1: When the ball valve is closed, the hollow main sealing strip 924 will correspond to the annular concave strip sealing ring 923. In the later stage, if there is a sealing problem between the ball 2 and the valve body 1, the hollow main sealing strip 924 and the annular concave strip sealing ring 923 will play an anti-leakage role for a period of time. Step 2: Furthermore, after leakage occurs between the sphere 2 and the valve body 1 at a later stage, the water source will enter the upper receiving groove 4 and the lower receiving groove 7 along the upper annular groove 3 and the lower annular groove 6 respectively. Subsequently, the first floating plate 92 and the second floating plate 96 will rise, the first leak-proof strip 94 will be inserted into the upper sealing groove 8, and the second leak-proof strip 98 will be inserted into the lower sealing groove 5 to intercept the partial water source leaking from the outside of the sphere 2, achieving automatic plugging, reducing the penetration of the water source. The first leak-proof strip 94 can also increase the sealing performance of the positions of the sphere 2 and the valve stem, avoiding water leakage from the valve stem; Step 3: The water source in the upper annular groove 3 enters the annular installation groove 17 through the diversion channel 18. After contacting the fourth packing 927, the hollow main sealing strip 924 will expand passively. When the ball valve is closed at a later stage, the hollow main sealing strip 924 can fully seal the gap between the sphere 2 and the annular recessed strip sealing ring 923 on the inner wall of the valve body 1, thereby automatically repairing the water leakage phenomenon of the ball valve, effectively increasing the normal service life of the ball valve, and automatically adjusting and improving the sealing effect when water leakage occurs during the closed period of the ball valve; Step 4: When the original sealing layer at the flange connection at both ends of the valve body 1 fails and is damaged, the water source will seep into the first water guide groove 13 and the second water guide groove 14. The water source contacts the third packing 919 through the porous strip groove 920, causing it to expand, thereby filling the sealing ring 917. The sealing ring 917 fully fills the gap after the sealing member fails, improving the sealing effect, achieving automatic repair and sealing of the water leakage position, and increasing the effective service life of the sealing at both ends of the ball valve.

8. A method for using an integrated high platform flange ball valve, the method being applied to the high platform flange ball valve according to claim 7, comprising the following steps: Step 1: When the ball valve is closed, the hollow main sealing strip (924) will correspond to the annular groove sealing ring (923). If there is a sealing problem between the ball (2) and the valve body (1) at a later stage, the hollow main sealing strip (924) and the annular groove sealing ring (923) will play an anti-leakage effect for a period of time; Step 2: Furthermore, when leakage occurs between the ball (2) and the valve body (1) at a later stage, the water source will flow along the upper annular groove (3) and the lower annular groove (6) into the upper receiving groove (4) and the lower receiving groove (7), respectively. Then, the first floating plate (92) and the second floating plate (96) will rise, and the first leakage-proof strip (94) will be inserted into the upper sealing groove (8), and the second leakage-proof strip (98) will be inserted into the lower sealing groove (5), so as to intercept the local water source leaking from the outside of the ball (2), realize automatic blocking, and reduce the amount of water infiltration. At the same time, the first leakage-proof strip (94) can increase the sealing performance of the position of the ball (2) and the valve stem, so as to prevent the valve stem from leaking. Step 3: The water source in the upper annular groove (3) enters the annular mounting groove (17) through the diversion channel (18). After contacting the fourth filler (927), the hollow main sealing strip (924) will passively expand. Later, when the ball valve is closed, the hollow main sealing strip (924) can fully block the gap between the ball body (2) and the annular concave strip sealing ring (923) on the inner wall of the valve body (1), thereby automatically repairing the leakage of the ball valve, effectively increasing the normal service life of the ball valve, and automatically adjusting and improving the sealing effect when the ball valve is in the closed period and leaking. Step 4: When the original sealing layer at the flange connection at both ends of the valve body (1) fails and is damaged, water will seep into the first water diversion groove (13) and the second water diversion groove (14). The water will contact the third filler (919) through the porous strip groove (920) to expand it, thereby filling the sealing ring (917). The sealing ring (917) fully fills the gap after the sealing component fails, thereby improving the sealing effect, realizing automatic repair and sealing of the leaking position, and increasing the effective use time of the seals at both ends of the ball valve.
