[0001] The present application relates to the field of valves, and in particular to a multifunctional ball valve. Background Art

[0002] A ball valve is a valve in which the ball is driven by the valve stem and rotates around the axis of the ball valve. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. It only needs to rotate 90 degrees and a very small torque to connect the through hole on the ball with the water inlet and outlet on the valve body to connect the pipeline. The ball closes the water inlet and outlet on the valve body to cut off the pipeline. It is most suitable for use as a switch and cut-off valve.

[0003] When the ball valve is used in areas with poor water quality, the water contains a lot of particulate impurities, which will enter the valve body and cause wear on the valve body, thereby reducing the control effect of the ball valve. At present, the ball valve is usually disassembled to clean the inside of the ball valve. The whole cleaning process is time-consuming and labor-intensive, and affects the use.

[0006] By adopting the above technical solution, the control mechanism controls the valve ball to rotate so that the through hole on the valve ball is connected with the water inlet and the water outlet of the valve body, so that the pipeline can be connected. At this time, the connecting piece abuts against the valve ball under the pressure of the water source, and the high-pressure channel and the water inlet of the valve body are closed.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] Example 1 The embodiment of the present application discloses a multifunctional ball valve.

[0033] Reference Figure 1 The multifunctional ball valve comprises a valve body 1, a valve ball 2, a control mechanism 3, a filtering mechanism 4, a cleaning mechanism 5 and a scraping mechanism 8. The interior of the valve body 1 is hollow. Both ends of the valve body 1 are respectively provided with an inlet end and an outlet end for communicating with a pipeline. The valve ball 2 is rotatably mounted on the inner wall of the valve body 1. A through hole is provided on the valve ball 2. By driving the valve ball 2 to rotate so that the through hole is connected with the inlet end and the outlet end of the valve body 1, the ball valve can be opened. By driving the valve ball 2 to rotate so that the non-hole side of the valve ball 2 closes the inlet end and the outlet end of the valve body 1, the ball valve can be closed.

[0034] Reference Figure 1 , Figure 2, the control mechanism 3 is installed on the valve body 1, and the control mechanism 3 is used to drive the valve ball 2 to rotate. The control mechanism 3 includes a valve stem 31, a plug connector 32 and a reset spring 33. The valve stem 31 is slidably and rotatably installed on the valve body 1, the plug connector 32 is installed at one end of the valve stem 31 close to the valve ball 2, and the cross-sectional shape of the plug connector 32 is polygonal. The end of the valve ball 2 close to the valve stem 31 is provided with a slot for plugging with the plug connector 32. The reset spring 33 is installed on the valve body 1, and the reset spring 33 is connected to the valve stem 31. The reset spring 33 always has a tendency to drive the valve stem 31 away from the valve ball 2.

[0035] The staff first presses the valve stem 31 so that the valve stem 31 drives the plug connector 32 to be plugged into the valve ball 2, and then rotates the valve stem 31. The valve stem 31 can drive the valve ball 2 to rotate to control the opening and closing of the ball valve. After the adjustment is completed, the staff releases the valve stem 31, and the return spring 33 drives the valve stem 31 away from the valve ball 2, and the plug connector 32 is disconnected from the valve ball 2. At this time, rotating the valve stem 31 no longer drives the valve ball 2 to rotate, reducing the possibility of accidentally touching the valve stem 31 and causing the valve ball 2 to shift, thereby ensuring the stability of the valve ball 2 after adjustment.

[0036] Reference Figure 1 , Figure 2 A packing 6 is installed on the valve body 1. The packing 6 can be made of materials such as polytetrafluoroethylene, graphite, carbon fiber, etc. In the present embodiment, the packing 6 is made of polytetrafluoroethylene. A sealing ring 7 is installed on the valve stem 31 at a section of the packing 6 close to the valve ball 2. A sealing groove for the sealing ring 7 to be embedded is circumferentially opened on the packing 6. The sealing ring 7 circumferentially abuts against the inner wall of the valve body 1, thereby increasing the force required to rotate the valve stem 31 and further reducing the possibility of accidentally touching the valve stem 31 and causing the valve ball 2 to shift.

[0037] The packing 6 fills the gap between the valve stem 31 and the valve body 1, improving the sealing between the valve stem 31 and the valve body 1. When the return spring 33 drives the valve stem 31 to move away from the valve ball 2, the valve stem 31 drives the sealing ring 7 to embed into the sealing groove. The sealing ring 7 seals the valve stem 31 and the packing 6, and then seals the valve stem 31 and the valve body 1, improving the sealing between the valve stem 31 and the valve body 1.

[0038] Reference Figure 1 , Figure 2A high-pressure channel is formed between the inner wall of the valve body 1 and the valve ball 2, and the high-pressure channel is used to communicate with the water inlet end of the valve body 1. The cleaning mechanism 5 is installed on the valve body 1, and the cleaning mechanism 5 is used to clean the valve body 1 and the valve ball 2. The cleaning mechanism 5 includes a connecting piece 51, a wedge 52, a driving assembly 53 and a discharge assembly 54. The connecting piece 51 is hingedly installed on the inner wall of the water inlet end of the valve body 1, and the connecting piece 51 is used to close the high-pressure channel and the water inlet end of the valve body 1. The wedge 52 is slidably installed on the valve body 1 in the direction toward the connecting piece 51. The diameter of the wedge 52 gradually increases from the direction close to the connecting piece 51 to the direction away from the connecting piece 51. The driving assembly 53 is installed on the valve body 1. The driving assembly 53 is used to drive the wedge 52 to slide toward the connecting piece 51 and push the connecting piece 51 away from the valve ball 2. The driving assembly 53 includes a driving screw 531, and the driving screw 531 is rotatably installed on the valve body 1 along the sliding direction of the wedge 52. The driving screw 531 is threadedly connected with the wedge 52.

[0039] The discharge component 54 is installed on the valve body 1. The discharge component 54 is used to discharge impurities in the valve body 1. The discharge component 54 includes a baffle 541, a sealing gasket 542 and a positioning bolt 543. A discharge port 11 is opened at the bottom of the valve body 1. The discharge port 11 is connected to the high-pressure channel. The baffle 541 is slidably installed on the valve body 1 and is used to close the discharge port 11. The sealing gasket 542 is installed on the side of the baffle 541 close to the valve body 1. The positioning bolt 543 is slidably penetrated on the baffle 541 and threaded into the valve body 1.

[0040] During normal use, the water source at the water inlet end of the valve body 1 impacts the connecting piece 51, so that the connecting piece 51 is pressed against the valve ball 2, and the high-pressure channel formed between the valve body 1 and the valve ball 2 is closed, reducing the possibility of impurities in the water source entering between the valve body 1 and the valve ball 2. When the valve body 1 and the valve ball 2 need to be cleaned, the valve ball 2 is first rotated to close the ball valve, and then the positioning bolt 543 is unscrewed, and the blocking cover 541 is removed from the valve body 1 to open the discharge port 11, and then the driving screw 531 is turned to make the wedge block 52 slide in the direction close to the connecting piece 51, and the wedge block 52 can push the connecting piece 51 away from the valve ball 2. At this time, the water inlet end of the valve body 1 is connected with the high-pressure channel, and the water source can rush into the high-pressure channel to flush the inner wall of the valve body 1 and the outer wall of the valve ball 2, so that the inner wall of the valve body 1 The impurities attached to the outer wall of the valve ball 2 and the valve ball 2 are flushed away, and the impurities and water source are discharged from the discharge port 11, and then the driving screw 531 is turned to make the wedge block 52 move away from the connecting piece 51. The connecting piece 51 is again pressed against the valve ball 2 under the impact of the water source, and the water inlet end of the valve body 1 and the high-pressure channel are closed. Then the stop cover 541 is moved to fit onto the discharge port 11, and the positioning bolt 543 is turned to make the sealing gasket 542 press against the discharge port 11, so that the discharge port 11 can be closed, which effectively reduces the amount of impurities adhering to the outer wall of the valve ball 2 and the inner wall of the valve body 1, reduces the corrosion of the valve body 1 and the valve ball 2 by impurities, and reduces the wear of the valve ball 2 and the valve body 1 by impurities when the valve ball 2 rotates, thereby improving the method of disassembling and cleaning the ball valve, thereby improving the problem of time-consuming and labor-intensive cleaning affecting the use when used in areas with poor water quality.

[0041] Reference Figure 1 , Figure 2, the filter mechanism 4 is installed on the valve body 1, and the filter mechanism 4 is used to filter the water source entering the valve body 1. The filter mechanism 4 includes a filter screen 41 and a brush assembly 42. The filter screen 41 is installed on the inner wall of the water inlet end of the valve body 1. In the present embodiment, the filter screen 41 is a stainless steel screen; the brush assembly 42 is installed on the valve body 1, and the brush assembly 42 is used to clean the filter screen 41. The brush assembly 42 includes a brush plate 421, a screw rod 422, an active bevel gear 423 and a driven bevel gear 424. The brush plate 421 is slidably installed on the valve body 1, and the brush plate 421 abuts against the filter screen 41. In the present embodiment, the brush plate 421 includes a main body, an extension body and a stretch spring. The main body is slidably installed on the valve body 1, and the extension body is slidably installed at both ends of the main body. The stretch spring is installed on the main body and is connected to the extension body. The extension spring always has a tendency to drive the extension body away from the main body, so that the length of the brush plate 421 during the movement can be extended and retracted following the diameter of the filter screen, so that the filter screen 41 can be brushed more comprehensively; the screw rod 422 is rotatably installed on the valve body 1, and the screw rod 422 is threadedly penetrated on the brush plate 421, and the active bevel gear 423 is rotatably installed on the valve body 1, and the active bevel gear 423 is coaxially connected with the driving screw rod 531, and the driven bevel gear 424 is coaxially installed on the screw rod 422. In this embodiment, a transmission rod group is installed on the valve body 1, and a bevel gear is coaxially installed at both ends of the transmission rod group. The bevel gears at both ends of the transmission rod group are respectively meshed with the active bevel gear 423 and the driven bevel gear 424, thereby realizing the transmission of the driven bevel gear 424 when the active bevel gear 423 rotates.

[0042] Before the water source enters the chamber of the valve body 1 accommodating the valve ball 2, the filter screen 41 filters the impurities in the water source to reduce the amount of impurities in the water source entering the chamber of the valve body 1 accommodating the valve ball 2. When the staff rotates the driving screw 531, the driving screw 531 drives the active bevel gear 423 to rotate, and the active bevel gear 423 drives the driven bevel gear 424 to rotate, and the driven bevel gear 424 drives the screw rod 422 to rotate, and the screw rod 422 can drive the brush plate 421 to slide, and the brush plate 421 slides from one end of the filter screen 41 to the other end, so as to brush off the impurities adhered to the filter screen 41, thereby ensuring the filtering effect of the filter screen 41. When the staff rotates the driving screw 531 in the opposite direction, the screw rod 422 can be driven to rotate in the opposite direction, so that the brush plate 421 is reset, and the filter screen 41 is cleaned again when the driving screw 531 rotates next time. The staff only needs to rotate the driving screw 531 to clean the filter screen 41 at the same time, thereby effectively improving the convenience of cleaning the filter screen 41.

[0043] Reference Figure 2 , Figure 3The scraping mechanism 8 is installed on the valve body 1. The scraping mechanism 8 is used to scrape the inner wall of the valve body 1 and the outer wall of the valve ball 2. The scraping mechanism 8 includes a first scraper 81 and a second scraper 82. Four first scrapers 81 are installed on the inner wall of the valve body 1. The four first scrapers 81 are circumferentially evenly spaced on the inner wall of the valve body 1. The four first scrapers 81 are all in contact with the outer wall of the valve ball 2. The first scraper 81 includes an arc segment 811, an extension segment 812 and an extension spring 813. The arc segment 811 is installed on the inner wall of the valve body 1. The arc segment 811 is open at one end away from the valve stem 31. The extension section 812 is slidably inserted in the end of the arc section 811 away from the valve stem 31, and the width of the extension section 812 gradually decreases from the end close to the arc section 811 to the end away from the arc section 811. The extension spring 813 is installed on the arc section 811, and the extension spring 813 is connected to the extension section 812. The extension spring 813 always has a tendency to drive the extension section 812 away from the arc section 811; four second scrapers 82 are installed on the valve ball 2, and the four second scrapers 82 are distributed on the valve ball 2 at equal intervals in the circumferential direction, and the four second scrapers 82 are all abutted against the inner wall of the valve body 1.

[0044] When the staff drives the valve ball 2 to rotate and turns the ball valve from closed to open, the second scraper 82 on the valve ball 2 rotates, and the second scraper 82 can scrape off the impurities adhered to the valve body 1, and the first scraper 81 on the valve body 1 can scrape off the impurities adhered to the outer wall of the valve ball 2, and during the scraping process, the extension spring 813 drives the extension section 812 away from the arc section 811, and the extension section 812 whose width gradually decreases from the end close to the arc section 811 to the end away from the arc section 811 can penetrate deeper into the gap between the ball valve and the valve ball 2, clean the impurities in the gap between the ball valve and the valve ball 2, and effectively improve the cleaning effect of the outer wall of the valve ball 2 and the inner wall of the valve body 1.

[0045] The implementation principle of Example 1 of the present application is as follows: the staff presses and rotates the valve stem 31, so that the valve ball 2 rotates to close the water inlet end of the valve body 1. During the rotation of the valve ball 2, the first scraper 81 and the second scraper 82 scrape off the impurities adhering to the outer wall of the valve ball 2 and the inner wall of the valve body 1, and then unscrew the positioning bolt 543, remove the blocking cover 541, so that the discharge port 11 is opened, and then the driving screw 531 is screwed so that the wedge block 52 pushes the connecting piece 51 away from the valve ball 2. At this time, the water inlet end of the valve body 1 is connected with the high-pressure channel formed between the valve body 1 and the valve ball 2, and the water source rushes into the high-pressure channel, and the valve is closed by impact. Impurities on the outer wall of the ball 2 and the inner wall of the valve body 1 are flushed away, and the impurities are discharged from the discharge port 11. At the same time, the screw 531 is driven to rotate, which drives the screw 422 to rotate, so that the brush plate 421 brushes impurities off the filter screen 41, cleans the filter screen 41, and ensures the filtering effect of the filter screen 41 on the water source entering the valve body 1 and the ball valve, thereby realizing the cleaning of the ball valve, reducing the corrosion of the valve body 1 and the valve ball 2 by impurities, and reducing the wear of the valve ball 2 and the valve body 1 by impurities when the valve ball 2 rotates, thereby improving the method of disassembling and cleaning the ball valve, thereby improving the problem of time-consuming and labor-intensive cleaning that affects use when used in areas with poor water quality.

[0046] Example 2 Reference Figure 4 , the difference between Example 2 of the present application and Example 1 is that: an adjusting mechanism 9 is installed on the valve body 1, and the adjusting mechanism 9 is used to control the water output of the valve body 1. The adjusting mechanism 9 includes an adjusting motor 91, a flow meter 92 and a controller 93. The adjusting motor 91 is installed on the valve body 1, and the adjusting motor 91 is coaxially connected to the valve stem 31.

The controller 93 is installed on the valve body 1, and the controller 93 is electrically connected to the adjusting motor 91 and the flow meter 92.

[0047] The implementation principle of Example 2 of the present application is: the flow meter 92 detects the flow at the water outlet end of the valve body 1, and the controller 93 can control the start of the adjustment motor 91 according to the flow data detected by the flow meter 92, and the adjustment motor 91 drives the valve stem 31 to rotate, and the valve stem 31 drives the valve ball 2 to rotate, thereby adjusting the angle of the valve ball 2, and then controlling the flow at the water outlet end of the ball valve, thereby conveniently realizing the flow control and opening and closing of the ball valve.
