[0018] 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.

[0019] Example: Figure 1-Figure 8 As shown, the present invention provides an exhaust ball valve with an internal self-cleaning function, including an exhaust ball valve body 1, the exhaust valve body including a connecting pipe 2 and an exhaust pipe 3, the exhaust pipe 3 is installed above the connecting pipe 2, a partition 31 is installed inside the exhaust pipe 3, the space below the partition 31 is a primary filter space 32, and the space above the partition 31 is a secondary filter space 33, a mounting plate 11 is installed at the connection between the connecting pipe 2 and the exhaust pipe 3, a power-assisted cleaning component 4 is installed between the mounting plates 11, a barrier component 5 is provided on the partition 31, an end cover 7 is installed above the exhaust pipe 3, an exhaust component 8 and a pressure gauge are installed on the end cover 7, the barrier component 5 is connected to the end cover 7, the power-assisted cleaning component 4 can clean the primary filter space 32, and the barrier component 5 can block the air entering the secondary filter space 33; When the device is in use, the exhaust ball valve needs to be connected to the pipe to be connected first. When the exhaust ball valve body 1 is used, the gas will first pass through the connecting pipe 2. When the other end of the connecting pipe 2 is closed, all the gas will rush to the exhaust pipe 3. When the device is connected to a pipe for transmitting liquid such as a water pipe, it is not necessary to close the other end of the connecting pipe 2. Then, when the liquid passes through the connecting pipe 2, the impact force of the liquid will drive the power-assisted cleaning component 4 to rotate, so that the power-assisted cleaning component 4 can clean the primary filtering space 32 of the device. At the same time, the excess gas in the water pipe will enter the exhaust pipe 3 of the device during the flow. When gas enters the exhaust pipe 3, it will first enter the primary filter space 32 and absorb a small amount of impurities. Then the air will pass through the partition 31 into the secondary filter space 33, and then the gas will be filtered for a second time through the secondary filter space 33. When the device needs to clean the secondary filter space 33, it only needs to rotate the barrier component 5. The barrier component 5 can block most of the gas, so that a small amount of gas can generate a greater impact force and blow toward the inner wall of the exhaust pipe 3 along the soot blowing hole 312, thereby completing self-cleaning. Then, according to the needs of the staff, they can decide whether to discharge the internal gas. At the same time, when the internal gas reaches a certain value, the gas inside the exhaust ball valve will push open the exhaust component 8, and then discharge the excess gas to prevent the internal pressure from rising directly. Therefore, when the device is in use, it can automatically clean the interior of the exhaust ball valve body 1, and can also assist the exhaust ball valve body 1 to clean itself as needed, effectively preventing the exhaust ball valve from being blocked, and also reducing the situation where the exhaust ball valve cannot be used normally.

[0020] like Figure 2-Figure 6 As shown, in this embodiment, specifically, a limiting ring 111 and a plurality of air inlet holes 112 are provided on the mounting plate 11, and the plurality of air inlet holes 112 are equidistantly arranged on the mounting plate 11, the limiting ring 111 is installed in the middle of the mounting plate 11, a bidirectional screw groove is installed inside the limiting ring 111, and an auxiliary cleaning component 4 is installed inside the limiting ring 111; The mounting plate 11 of the device is mainly used to guide the gas and limit the position of the power-assisted cleaning component 4 so that the power-assisted cleaning component 4 can work in a specific area. When the mounting plate 11 is used, the gas will enter the exhaust pipe 3 through the air inlet 112, and the limiting ring 111 can limit the position of the power-assisted cleaning component 4, so that the power-assisted cleaning component 4 can move back and forth in the limiting ring 111, thereby realizing self-cleaning of the exhaust ball valve body 1.

[0021] like Figure 3-Figure 5 As shown, in this embodiment, specifically, the power-assisted cleaning assembly 4 includes a fixing rod 41, one end of the fixing rod 41 located inside the connecting pipe 2 is equipped with a blade 42, one end of the fixing rod 41 located at the exhaust pipe 3 is equipped with multiple groups of brushes, and a bidirectional thread is provided on the outside of the fixing rod 41, and the fixing rod 41 cooperates with the bidirectional screw groove of the limiting ring 111 through the bidirectional thread; When in use, the auxiliary cleaning component 4 of the device can assist itself in cleaning the primary filter space 32 through the power of external gas or liquid. During specific use, when the liquid or gas impacts the blade 42, the blade 42 will rotate under the impact of the water flow or gas, thereby driving the fixed rod 41 to rotate in the limiting ring 111. Because the fixed rod 41 and the limiting ring 111 are matched through a two-way thread and a two-way screw groove, the fixed rod 41 will be blocked when it rotates to the top of one end, thereby changing the direction of the fixed rod 41 so that the fixed rod 41 can flip over. When it flips to the top of the other end, it will also be blocked and flip again, thereby performing reciprocating motion. At this time, the brush on the fixed rod 41 will clean the exhaust pipe 3, and the brush on the blade 42 will clean the mounting plate 11.

[0022] like Figure 2-Figure 3 As shown, in this embodiment, specifically, a blocking hole 311 and a plurality of groups of soot blowing holes 312 are opened on the partition plate 31, an air blocking component 6 is installed at the bottom of the partition plate 31, the air blocking component 6 cooperates with the soot blowing holes 312, a magnet is installed in the middle of the blocking hole 311, a magnet is installed at the bottom of the soot blowing hole 312, and the blocking hole 311 cooperates with the blocking component 5; The main function of the partition 31 of the device is to divide the exhaust pipe 3 into two spaces. The main function of the blocking hole 311 located on the partition 31 is to cooperate with the blocking component 5 to achieve the discharge pressure and achieve different cleaning effects. The soot blowing hole 312 on the partition 31 is used to clean the secondary filter space 33. When the blowing hole is not in use, it will attract the air isolation component 6 to close itself to prevent the gas from entering the secondary filter space 33 through the soot blowing hole 312, so that the gas can only enter the secondary filter space 33 through the blocking hole 311.

[0023] like Figure 7 As shown, in this embodiment, specifically, the air barrier assembly 6 includes a baffle 61 and two groups of limit blocks 62, the two groups of limit blocks 62 are installed at the bottom of the baffle 31, one side of the baffle 61 is installed between the two groups of limit blocks 62 through a bearing, the baffle 61 is made of a magnetic metal, and the baffle 61 can cooperate with the blocking hole 311 and the blocking assembly 5 respectively; When the air barrier component 6 of the device is in use, it can block the gas from entering the secondary filtration space 33 through the soot blowing hole 312. During specific use, the baffle 61 can rotate between the two sets of limit blocks 62 through the bearing. Because a magnet is provided at the bottom of the soot blowing hole 312 and the partition 31 is made of magnetic metal, the partition 31 is attracted to the magnet and adsorbed. At the same time, the air from bottom to top will also strengthen the connection between the two.

[0024] like Figure 2As shown, in this embodiment, specifically, the blocking assembly 5 includes a connecting rod 51, a connecting rod 52 is installed at the bottom of the connecting rod 51, a magnetic ball 53 is installed at the other end of the connecting rod 52, the diameter of the magnetic ball 53 is the same as the diameter of the blocking hole 311, a hand-held plate is installed at the other end of the connecting rod 51, the connecting rod 51 is threadedly connected to the end cover 7, and a sealing ring is provided at the connection between the connecting rod 51 and the end cover 7; When in use, the barrier component 5 of the device can block the gas. During specific use, the staff needs to rotate the handheld plate, and then rotate the entire connecting rod 51. When the connecting rod 51 rotates, the magnetic ball 53 at the bottom will also move in the rotation direction. Because the magnetic ball 53 has the same diameter as the barrier hole 311, the barrier hole 311 can be closed to prevent gas from passing through the barrier hole 311 into the secondary filter space 33. At the same time, when exhaust is required, it is necessary to rotate the connecting rod 51 to keep the magnetic ball 53 away from the barrier hole 311, so that air can enter the secondary filter space 33 through the barrier hole 311.

[0025] like Figure 2 As shown, in this embodiment, specifically, when the magnetic ball 53 is located above the blocking hole 311: the baffle 61 is attracted by the soot blowing hole 312, and the air enters the second filter space through the blocking hole 311; When the distance between the magnetic ball 53 and the blocking hole 311 gradually decreases, the air flowing into the second filter space will also decrease; When the magnetic ball 53 closes the blocking hole 311, no air enters the secondary filtering space 33; When the magnetic ball 53 is partially located at the bottom of the partition 31: the bottom of the magnetic ball 53 attracts the baffle 61, and the air enters the secondary filter space 33 through the soot blowing hole 312; The magnetic ball 53 can achieve different effects at different positions. At the same time, when the magnetic ball 53 is at different positions, the gas inside the device will also be different. Then, by observing the pressure gauge, the current position of the magnetic ball 53 can be known, thereby realizing the above four working states.

[0026] like Figure 1-Figure 4 and Figure 8 As shown, in this embodiment, specifically, an exhaust hole 71 is opened above the end cover 7, an exhaust assembly 8 is installed inside the exhaust hole 71, a groove is opened on the inner wall of the exhaust hole 71, and the exhaust assembly 8 includes an exhaust plug 81, and a plurality of groups of limiting rods 82 are installed at the lower end of the exhaust plug 81. A rubber ring is installed between the upper end of the exhaust plug 81 and the end cover 7, and the rubber ring cooperates with the exhaust hole 71, and the limiting rod 82 can move in the groove; When in use, the exhaust component 8 can assist in exhausting the gas, and can also close the exhaust component 8 to block the air from being discharged from the exhaust pipe 3. During specific use, the exhaust plug 81 can seal the exhaust hole 71, but when the air pressure in the secondary filter space 33 is relatively high, the exhaust plug 81 will be pushed open, allowing the air to be released by itself. The limiting rod 82 under the exhaust plug 81 is mainly used to prevent the impact force of the air pressure from impacting the exhaust plug 81, and to limit the position of the exhaust plug 81 so that the gas can pass through the groove and then be discharged from the exhaust pipe 3.

[0027] like Figure 2-Figure 5 As shown, in this embodiment, specifically, a plurality of groups of arc blocks 21 are installed inside the connecting pipe 2, and the plurality of groups of arc blocks 21 are installed equidistantly inside the connecting pipe 2, and the middle height of the arc blocks 21 is higher than the heights at both ends; When gas or liquid passes through the device, the previously lost flow rate can be restored. When the gas or liquid passes through the lower part of the arc block 21, which is also the inlet of the connecting pipe 2 of the device, because the space at the inlet of the connecting pipe 2 is larger, the flow rate is the same as before. As the gas or liquid gradually moves, the space for the gas or liquid to pass through will gradually shrink, and then the flow rate will be increased to a certain extent, so that the air or gas initially entering the connecting pipe 2 can have a flow rate greater than the gas or liquid discharged from the connecting pipe 2, thereby increasing the flow rate of the liquid or gas.

[0028] like Figure 1-Figure 5 As shown, in this embodiment, specifically, the output end of the pressure gauge is located in the secondary filtering space 33, and the pressure gauge can monitor the air pressure of the secondary filtering space 33; The pressure gauge of the device can help the staff to monitor the liquid inside the device. At the same time, the pressure gauge can assist the staff to adjust the position of the magnetic ball 53 to achieve different effects.

[0029] Working principle: When the device is in use, the exhaust ball valve needs to be connected to the pipe to be connected first. When the exhaust ball valve body 1 is used, the gas will first pass through the connecting pipe 2. When the other end of the connecting pipe 2 is closed, all the gas will rush to the exhaust pipe 3. When the device is connected to a pipe for transmitting liquid such as a water pipe, it is not necessary to close the other end of the connecting pipe 2. Then, when the liquid passes through the connecting pipe 2, the impact force of the liquid will drive the power-assisted cleaning component 4 to rotate, so that the power-assisted cleaning component 4 can clean the primary filter space 32 of the device. At the same time, the excess gas in the water pipe will enter the exhaust pipe 3 of the device during the flow. When gas enters the exhaust pipe 3, it will first enter the primary filter space 32 and absorb a small amount of impurities. Then the air will pass through the partition 31 into the secondary filter space 33, and then the gas will be filtered for a second time through the secondary filter space 33. When the device needs to clean the secondary filter space 33, it only needs to rotate the barrier component 5. The barrier component 5 can block most of the gas, so that a small amount of gas can generate a greater impact force and blow toward the inner wall of the exhaust pipe 3 along the soot blowing hole 312, thereby completing self-cleaning. Then, according to the needs of the staff, they can decide whether to discharge the internal gas. At the same time, when the internal gas reaches a certain value, the gas inside the exhaust ball valve will push open the exhaust component 8, and then discharge the excess gas to prevent the internal pressure from rising directly. Therefore, when the device is in use, it can automatically clean the interior of the exhaust ball valve body 1, and can also assist the exhaust ball valve body 1 to clean itself as needed, effectively preventing the exhaust ball valve from being blocked, and also reducing the situation where the exhaust ball valve cannot be used normally.

[0030] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
