Description

An exhaust ball valve with internal self-cleaning function Technical Field

[0001] This invention relates to the field of exhaust ball valve technology, specifically an exhaust ball valve with an internal self-cleaning function. Background Technology

[0002] A ball valve is a common control device that can connect or disconnect the flow path of the medium inside the valve body, and is therefore widely used in various pipelines.

[0003] A ball valve typically consists of a valve body, a valve stem, a handle, and a valve core housed within the valve body. One end of the valve stem is connected to the valve core, and the other end is connected to the handle. During use, rotating the handle drives the valve stem and valve core to rotate, thereby opening or closing the flow channel of the medium within the valve body. An exhaust ball valve combines the features of an exhaust valve and a ball valve. However, existing exhaust valves or ball valves do not have a self-cleaning function. Consequently, when gas is transmitted, particles carried in the gas will adhere to the inner wall of the valve body. Over time, this will affect the use of the valve body and its performance when transmitting gas. Summary of the Invention

[0004] The purpose of this invention is to provide an exhaust ball valve with an internal self-cleaning function to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an exhaust ball valve with an internal self-cleaning function, comprising an exhaust ball valve body, the exhaust valve body including a connecting pipe and an exhaust pipe, the exhaust pipe being installed above the connecting pipe, a partition being installed inside the exhaust pipe, the space below the partition being a primary filtration space, the space above the partition being a secondary filtration space, an mounting plate being installed at the connection between the connecting pipe and the exhaust pipe, an auxiliary cleaning component being installed between the mounting plates, a blocking component being provided on the partition, an end cap being installed above the exhaust pipe, an exhaust component and a pressure gauge being installed on the end cap, and the blocking component being connected to the end cap, the auxiliary cleaning component being able to clean the primary filtration space, and the blocking component being able to block air from entering the secondary filtration space.

[0006] Furthermore, the mounting plate has a limiting ring and multiple sets of air inlets, which are equidistantly arranged on the mounting plate. The limiting ring is installed in the middle of the mounting plate, and a bidirectional screw groove is installed inside the limiting ring. An auxiliary cleaning component is installed inside the limiting ring.

[0007] Furthermore, the cleaning assist component includes a fixing rod, one end of which is located inside the connecting pipe and is equipped with blades, and the other end of which is located in the exhaust pipe and is equipped with multiple sets of brushes. The fixing rod is provided with bidirectional threads on its exterior and engages with the bidirectional threaded groove of the limiting ring through the bidirectional threads.

[0008] Furthermore, the partition plate is provided with a barrier hole and multiple sets of soot blowing holes. An air-blocking component is installed at the bottom of the partition plate. The air-blocking component cooperates with the soot blowing holes. A magnet is installed in the middle of the barrier hole and a magnet is installed at the bottom of the soot blowing hole. The barrier hole cooperates with the barrier component.

[0009] Furthermore, the air-barrier assembly includes a baffle and two sets of limiting blocks. The two sets of limiting blocks are installed at the bottom of the baffle. One side of the baffle is installed between the two sets of limiting blocks via a bearing. The baffle is made of a magnetic metal and can cooperate with the blocking hole and the blocking assembly respectively.

[0010] Furthermore, the barrier assembly includes a connecting rod, a connecting rod is installed at the bottom of the connecting rod, a magnetic ball is installed at the other end of the connecting rod, the diameter of the magnetic ball is the same as the diameter of the barrier hole, a hand-held plate is installed at the other end of the connecting rod, the connecting rod is threaded to the end cap, and a sealing ring is provided at the connection between the connecting rod and the end cap.

[0011] Furthermore, when the magnetic ball is positioned above the barrier hole: the baffle is attracted by the dust blowing hole, and air enters the second filtration space through the barrier hole;

[0012] As the distance between the magnetic ball and the barrier hole gradually decreases, the amount of air flowing into the second filtration space also decreases.

[0013] When the magnetic ball seals the barrier hole, no air will enter the secondary filtration space.

[0014] When the magnetic ball is located at the bottom of the partition, the bottom of the magnetic ball will attract the baffle, and air will enter the secondary filtration space through the dust blowing hole.

[0015] Furthermore, an exhaust hole is provided on the top of the end cap, an exhaust assembly is installed inside the exhaust hole, a groove is provided on the inner wall of the exhaust hole, the exhaust assembly includes an exhaust plug, multiple sets of limiting rods are installed at the lower end of the exhaust plug, a rubber ring is installed between the upper end of the exhaust plug and the end cap, the rubber ring cooperates with the exhaust hole, and the limiting rods can move within the groove.

[0016] Furthermore, multiple sets of arc-shaped blocks are installed inside the connecting pipe, and the multiple sets of arc-shaped blocks are installed at equal intervals inside the connecting pipe, with the height of the middle part of the arc-shaped block being higher than the height of the two ends.

[0017] Furthermore, the output terminal of the pressure gauge is located within the secondary filtration space, and the pressure gauge can monitor the air pressure in the secondary filtration space.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The cleaning-assisted component cleans the inner wall of the primary filtration space on its own. At the same time, the cleaning-assisted component can also filter and block dust in the gas when it rotates, preventing excessive gas from affecting the normal use of the exhaust ball valve and indirectly increasing the service life of the exhaust ball valve.

[0020] 2. By adjusting the position of the blocking component, different effects can be achieved. When the blocking component is closed to the blocking hole, the gas can be sealed off, and the valve will not allow air to flow out. When the blocking component extends beyond the blocking hole, it will attract the air-blocking component, increasing the pressure of the gas entering the secondary filtration space. The high-speed airflow can effectively clean the secondary filtration space.

[0021] 3. By using the arc-shaped block inside the connecting pipe, the loss of liquid or gas before entering the device can be restored, increasing the flow rate of the liquid or gas, so that the liquid or gas can be transported to the place where it is needed more quickly.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: As shown in Figures 1-8, 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 includes 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 filtration space 32, and the space above the partition 31 is a secondary filtration space 33. An installation plate 11 is installed at the connection between the connecting pipe 2 and the exhaust pipe 3. An auxiliary cleaning component 4 is installed between the installation plates 11. A barrier component 5 is provided on the partition 31. An end cap 7 is installed above the exhaust pipe 3. An exhaust component 8 and a pressure gauge are installed on the end cap 7. The barrier component 5 is connected to the end cap 7. The auxiliary cleaning component 4 can clean the primary filtration space 32, and the barrier component 5 can block air from entering the secondary filtration space 33.

[0033] When using this device, the first step is to connect the exhaust ball valve to the pipe to be connected. When the exhaust ball valve body 1 is in use, 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 liquid transmission pipe such as a water pipe, it is not necessary to close the other end of the connecting pipe 2. When the liquid passes through the connecting pipe 2, the impact force of the liquid will drive the auxiliary cleaning component 4 to rotate, so that the auxiliary cleaning component 4 can clean the primary filtration space 32 of the device. At the same time, excess gas in the water pipe will enter the exhaust pipe 3 of the device during the flow.

[0034] When gas enters the exhaust pipe 3, it first enters the primary filtration space 32, where a small amount of impurities are adsorbed. Then, the air passes through the baffle 31 and enters the secondary filtration space 33, where it undergoes secondary filtration. When the secondary filtration space 33 needs cleaning, the device simply rotates the blocking component 5. This component blocks most of the gas, allowing the remaining gas to generate a greater impact force and be blown along the blowing hole 312 towards the inner wall of the exhaust pipe 3, thus completing self-cleaning. Depending on the operator's needs, the internal gas can be discharged. When the internal gas reaches a certain value, the gas inside the exhaust ball valve will push open the exhaust component 8, thereby discharging the excess gas and preventing the internal pressure from rising continuously. Thus, the device can automatically clean the inside of the exhaust ball valve body 1 during use and can also assist the exhaust ball valve body 1 in cleaning itself as needed, effectively preventing blockage of the exhaust ball valve and reducing the likelihood of the exhaust ball valve malfunctioning.

[0035] As shown in Figures 2-6, in this embodiment, specifically, a limiting ring 111 and multiple sets of air inlets 112 are provided on the mounting plate 11. The multiple sets of air inlets 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. An auxiliary cleaning component 4 is installed inside the limiting ring 111.

[0036] The mounting plate 11 of the device is mainly used to guide the gas flow and limit the position of the auxiliary cleaning component 4, so that the auxiliary cleaning component 4 can work in a specific area. When the mounting plate 11 is in use, the gas will enter the interior of the exhaust pipe 3 through the air inlet 112, and the limiting ring 111 can limit the position of the auxiliary cleaning component 4, so that the auxiliary cleaning component 4 can move back and forth within the limiting ring 111, thereby realizing the self-cleaning of the exhaust ball valve body 1.

[0037] As shown in Figures 3-5, in this embodiment, specifically, the cleaning assistance component 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. Multiple sets of brushes are installed at one end of the fixing rod 41 located in the exhaust pipe 3. The fixing rod 41 is provided with a bidirectional thread on the outside. The fixing rod 41 is engaged with the bidirectional threaded groove of the limiting ring 111 through the bidirectional thread.

[0038] When in use, the auxiliary cleaning component 4 of this device can be powered by external gas or liquid to assist in cleaning the primary filtration space 32. Specifically, when liquid or gas impacts the blade 42, the blade 42 will rotate under the impact of water or gas, thereby driving the fixed rod 41 to rotate within the limiting ring 111. Because the fixed rod 41 and the limiting ring 111 are engaged by bidirectional threads and bidirectional grooves, when the fixed rod 41 rotates to the top of one end, it will be blocked, thereby changing the direction of the fixed rod 41 and allowing the fixed rod 41 to flip. When it flips to the top of the other end, it will also be blocked, thus flipping 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.

[0039] As shown in Figures 2 and 3, in this embodiment, specifically, the partition 31 is provided with a barrier hole 311 and multiple sets of soot blowing holes 312. An air-blocking component 6 is installed at the bottom of the partition 31. The air-blocking component 6 cooperates with the soot blowing holes 312. A magnet is installed in the middle of the barrier hole 311, and a magnet is installed at the bottom of the soot blowing holes 312. The barrier hole 311 cooperates with the barrier component 5.

[0040] The main function of the partition 31 is to divide the exhaust pipe 3 into two spaces. The main function of the barrier hole 311 on the partition 31 is to work with the barrier component 5 to achieve different cleaning effects by adjusting the exhaust pressure. The soot blowing hole 312 on the partition 31 is used to clean the secondary filtration space 33. When the soot blowing hole is not in use, it will attract the air-blocking component 6 to seal itself, preventing gas from entering the secondary filtration space 33 through the soot blowing hole 312, so that gas can only enter the secondary filtration space 33 through the barrier hole 311.

[0041] As shown in Figure 7, in this embodiment, specifically, the air-blocking component 6 includes a baffle 61 and two sets of limiting blocks 62. The two sets of limiting blocks 62 are installed at the bottom of the baffle 31. One side of the baffle 61 is installed between the two sets of limiting blocks 62 through a bearing. The baffle 61 is made of a magnetic metal. The baffle 61 can cooperate with the blocking hole 311 and the blocking component 5 respectively.

[0042] When in use, the air-blocking component 6 of the device can prevent gas from entering the secondary filtration space 33 through the soot blowing hole 312. In specific use, the baffle 61 can rotate between the two sets of limiting blocks 62 through the bearing. Since the bottom of the soot blowing hole 312 is equipped with a magnet, and the material of the baffle 31 is a magnetic metal, the baffle 31 is attracted to the magnet. At the same time, the air from bottom to top will also strengthen the connection between the two.

[0043] As shown in Figure 2, in this embodiment, specifically, the blocking component 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;

[0044] When in use, the barrier component 5 of the device can block gas. In specific use, the operator needs to rotate the hand lever, which in turn rotates the entire connecting rod 51. When the connecting rod 51 rotates, the magnetic ball 53 at the bottom will also move in the direction of rotation. Since the magnetic ball 53 has the same diameter as the barrier hole 311, it can seal the barrier hole 311 and prevent gas from entering the secondary filtration space 33 through the barrier hole 311. At the same time, when exhaust is required, the connecting rod 51 needs to be rotated to move the magnetic ball 53 away from the barrier hole 311, so that air can enter the secondary filtration space 33 through the barrier hole 311.

[0045] As shown in Figure 2, in this embodiment, specifically, when the magnetic ball 53 is located above the barrier hole 311: the baffle 61 is attracted by the blowing hole 312, and the air enters the second filter space through the barrier hole 311;

[0046] As the distance between the magnetic ball 53 and the barrier hole 311 gradually decreases, the amount of air flowing into the second filtration space also decreases.

[0047] When the magnetic ball 53 makes contact with the closed barrier hole 311, no air will enter the secondary filtration space 33.

[0048] When the magnetic ball 53 is located at the bottom of the partition 31: the bottom of the magnetic ball 53 will attract the baffle 61, and air will enter the secondary filtration space 33 through the blowing hole 312;

[0049] The magnetic ball 53 can achieve different effects in different positions. At the same time, the gas inside the device will be different in different positions of the magnetic ball 53. By observing the pressure gauge, the current position of the magnetic ball 53 can be determined, thereby realizing the above four working states.

[0050] As shown in Figures 1-4 and 8, in this embodiment, specifically, an exhaust hole 71 is provided above the end cap 7, an exhaust assembly 8 is installed inside the exhaust hole 71, a groove is provided on the inner wall of the exhaust hole 71, the exhaust assembly 8 includes an exhaust plug 81, multiple sets 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 cap 7, the rubber ring cooperates with the exhaust hole 71, and the limiting rods 82 can move within the groove;

[0051] When in use, the exhaust assembly 8 can assist in the discharge of gas, or it can seal the exhaust assembly 8 to block the air from being discharged from the exhaust pipe 3. In specific use, the exhaust plug 81 can block the exhaust hole 71. However, when the air pressure in the secondary filter space 33 is high, it will push open the exhaust plug 81, allowing the air to be released on its own. The limiting rod 82 under the exhaust plug 81 is mainly to prevent the impact force of the air pressure from pushing the exhaust plug 81 out, and to limit the position of the exhaust plug 81 so that the gas can pass through the groove and be discharged from the exhaust pipe 3.

[0052] As shown in Figures 2-5, in this embodiment, specifically, multiple sets of arc-shaped blocks 21 are installed inside the connecting pipe 2. The multiple sets of arc-shaped blocks 21 are installed at equal intervals inside the connecting pipe 2, and the height of the middle part of the arc-shaped block 21 is higher than the height of the two ends.

[0053] When gas or liquid passes through this device, the previously lost flow rate can be restored. When gas or liquid passes through the lower part of the arc-shaped block 21, which is also the inlet of the connecting pipe 2 of the device, the space at the inlet of the connecting pipe 2 is relatively large, and the flow rate is the same as before. As the gas or liquid gradually moves, the space through which the gas or liquid passes will gradually shrink, thereby increasing the flow rate to a certain extent. This allows the flow rate of the air or gas initially entering the connecting pipe 2 to be greater than that of the gas or liquid exiting the connecting pipe 2, thereby increasing the flow rate of the liquid or gas.

[0054] As shown in Figures 1-5, in this embodiment, specifically, the output end of the pressure gauge is located inside the secondary filtration space 33, and the pressure gauge can monitor the air pressure of the secondary filtration space 33;

[0055] The pressure gauge on this device helps staff monitor the liquid inside the device. It also helps staff adjust the position of the magnetic ball 53 to achieve different effects.

[0056] Working principle: When using this device, the first step is to connect the exhaust ball valve to the pipe to be connected. When the exhaust ball valve body 1 is in use, 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 liquid transmission pipe such as a water pipe, it is not necessary to close the other end of the connecting pipe 2. When the liquid passes through the connecting pipe 2, the impact force of the liquid will drive the auxiliary cleaning component 4 to rotate, so that the auxiliary cleaning component 4 can clean the primary filtration space 32 of the device. At the same time, excess gas in the water pipe will enter the exhaust pipe 3 of the device during the flow.

[0057] When gas enters the exhaust pipe 3, it first enters the primary filtration space 32, where a small amount of impurities are adsorbed. Then, the air passes through the baffle 31 and enters the secondary filtration space 33, where it undergoes secondary filtration. When the secondary filtration space 33 needs cleaning, the device simply rotates the blocking component 5. This component blocks most of the gas, allowing the remaining gas to generate a greater impact force and be blown along the blowing hole 312 towards the inner wall of the exhaust pipe 3, thus completing self-cleaning. Depending on the operator's needs, the internal gas can be discharged. When the internal gas reaches a certain value, the gas inside the exhaust ball valve will push open the exhaust component 8, thereby discharging the excess gas and preventing the internal pressure from rising continuously. Thus, the device can automatically clean the inside of the exhaust ball valve body 1 during use and can also assist the exhaust ball valve body 1 in cleaning itself as needed, effectively preventing blockage of the exhaust ball valve and reducing the likelihood of the exhaust ball valve malfunctioning.

[0058] It will be apparent to those skilled in the art that the present 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 its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
