Description

Technical Field

[0001] The utility model relates to the technical field of easily detachable ball valves, in particular to a highly sealed easily detachable ball valve. Background Art

[0002] A sealing ring, typically made of an elastic material, is placed between the ball and the valve seat. When the ball rotates to the closed position, the ring presses tightly against the ball, creating a tight seal to prevent fluid leakage. This sealing method not only ensures the valve's sealing performance, but also reduces friction when the valve is opened and closed, extending the valve's service life.

[0003] After both ends of the existing ball valve are connected to the pipeline, the water pump starts to work to pump water into the ball valve through the water inlet pipe at one end, and the ball valve outputs the internal water to the water outlet pipe at one end. However, when the water enters the ball valve, due to the presence of impurities in the water, the impurities accumulate inside the ball valve, and the internal components of the ball valve are corroded, so that the ball valve needs to be repaired, resulting in the ball valve being unable to work during the repair process, thereby increasing the working time. Utility Model Content

[0004] In order to overcome the problem that after the two ends of the existing ball valve are connected to the pipeline, the ball valve starts to work and water is pumped into the ball valve through the water inlet pipe at one end, and then the internal water is transmitted to the water outlet pipe at the other end for input. However, when the water enters the ball valve, there are impurities in the water itself, which causes the impurities to accumulate inside the ball valve, causing the internal components of the ball valve to be corroded, thereby requiring the ball valve to be repaired, resulting in insufficient extended working time. The embodiment of the present application provides a high-sealing and easy-to-disassemble ball valve. When one end of the ball valve body is connected to the water inlet pipe and water needs to be input into the ball valve body, the water enters the water inlet pipe and flows into the ball valve body. The water flowing inside the water inlet pipe is filtered by the filter screen installed by the coupling strip inside the water inlet pipe, so that all impurities in the water are filtered out and will not enter the ball valve body, thereby not causing corrosion to the inside of the ball valve body. The filter screen is slidably connected to the connecting groove in the middle of the coupling strip through a mounting rod installed on one side, so that when replacing the filter screen, you only need to pull out the filter screen to avoid the filter screen being blocked by other impurities and affecting the water flow.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A high-sealing and easy-to-assemble and disassemble ball valve comprises a ball valve body;

[0007] A water inlet pipe is provided at one end of the ball valve body;

[0008] Among them, a connecting strip is fixedly installed on the inner middle part of the water inlet pipe, and a plurality of connecting grooves are opened inside the connecting strip. A mounting rod is fixedly connected inside the connecting groove, and a filter screen is fixedly connected to one end of the mounting rod. The mounting rod is slidably connected to the connecting groove.

[0009] In a possible implementation, a lifting rod is fixedly installed at the middle end of the filter screen, one end of the lifting rod is fixedly connected to a force-bearing block, and one side of the force-bearing block is in contact with one side of the filter screen.

[0010] In a possible implementation, connecting pipes are fixedly installed at both ends of the ball valve body, one end of the connecting pipe is fixedly connected to a flange connecting port, and one end of the flange connecting port is connected to a water inlet pipe.

[0011] In a possible implementation, a sphere is provided inside the ball valve body, and an upper end of the sphere is connected to a rotating rod.

[0012] In a possible implementation, a mounting groove is provided at the middle end of the ball valve body, and the rotating rod extends to the outside of the ball valve body through the mounting groove.

[0013] In a possible implementation, a fixing nut is provided at the top of the rotating rod, and an adjustment handle is provided at the lower end of the fixing nut.

[0014] In a possible implementation, a fixing slot is formed at one end of the adjustment handle, and the adjustment handle is connected to the rotating rod through the fixing slot.

[0015] In summary, the present invention has at least one of the following beneficial technical effects:

[0016] 1. The water flowing inside the water inlet pipe is filtered through the filter screen installed in the joint strip inside the water inlet pipe, so that the impurities in the water are filtered out and will not enter the ball valve body, thereby preventing the ball valve body from being corroded;

[0017] 2. Filter impurities in the water through the filter. When too many impurities accumulate inside the filter and the filter needs to be replaced, pull the lifting rod and the filter out of the water inlet pipe, and push the new filter into the water inlet pipe to prevent the filter from being blocked by other impurities and affecting the flow of water.

[0025] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0026] Example 1:

[0027] This embodiment introduces the specific structure of a high-sealing and easy-to-assemble and disassemble ball valve. Figures 1-6 As shown, it includes a ball valve body 1 and a water inlet pipe 2. The water inlet pipe 2 is arranged at one end of the ball valve body 1. A connecting strip 3 is fixedly installed in the middle of the inner side of the water inlet pipe 2. A plurality of connecting grooves 4 are opened inside the connecting strip 3. A mounting rod 5 is fixedly connected to the inner side of the connecting groove 4. A filter screen 6 is fixedly connected to one end of the mounting rod 5. The mounting rod 5 is slidably connected to the connecting groove 4.

[0028] Among them, when one end of the ball valve body 1 is connected to the water inlet pipe 2 and water needs to be input into the ball valve body 1, the water enters the water inlet pipe 2 and flows into the ball valve body 1. The water flowing in the water inlet pipe 2 is filtered by the filter screen 6 installed by the connecting strip 3 inside the water inlet pipe 2, so that all impurities in the water are filtered out and will not enter the interior of the ball valve body 1, thereby not causing corrosion to the interior of the ball valve body 1. The filter screen 6 is slidably connected to the connecting groove 4 in the middle of the connecting strip 3 through the mounting rod 5 installed on one side, so that when replacing the filter screen 6, it is only necessary to pull out the filter screen 6, so as to prevent the filter screen 6 from being blocked by other impurities and affecting the flow of water;

[0029] At the same time, a lifting rod 9 is fixedly installed at the middle end of the filter 6, and one end of the lifting rod 9 is fixedly connected to a force block 10. When too many impurities accumulate inside the filter 6 and the filter 6 needs to be replaced, the lifting rod 9 at the middle end of the filter 6 is pulled out to the outside of the water inlet pipe 2, and the new filter 6 is pushed into the water inlet pipe 2, making it more convenient to replace the filter 6 without affecting the operation of the ball valve body 1;

[0030] Secondly, the ball valve body 1 is connected to the water inlet pipe 2 through the flange connection port 8 fixed at one end of the connecting pipe 7 at both ends, so that the connecting pipe 7 fits well with the ball valve body 1 to increase the sealing performance. When the water inlet pipe 2 fills water into the ball valve body 1, water will not leak from the connection, thereby ensuring the sealing performance of the ball valve body 1.

[0031] By adopting the above technical solutions:

[0032] In the above design, when one end of the ball valve body 1 is connected to the water inlet pipe 2, water is input into the ball valve body 1, so that when the water enters the water inlet pipe 2 and flows into the ball valve body 1, the filter screen 6 installed by the joint bar 3 inside the water inlet pipe 2 filters the water flowing inside the water inlet pipe 2, so that all impurities in the water are filtered out, thereby not causing corrosion to the interior of the ball valve body 1, and preventing the filter screen 6 from being blocked by other impurities and affecting the flow of water.

[0033] Example 2:

[0034] Based on Example 1, this example introduces the specific structure of the ball valve body 1. The ball valve body 1 is provided with a ball 11 inside, and the upper end of the ball 11 is connected to a rotating rod 12;

[0035] Among them, when it is necessary to allow water to flow inside the ball valve body 1, the ball valve body 1 is opened and closed by rotating the ball 11, and by rotating the rotating rod 12 at the upper end of the ball 11, when the rotating rod 12 is turned to the left, the ball 11 is driven to rotate to the left, so that the channel inside the ball 11 is connected to the water inlet at the middle end of the water inlet pipe 2, so that the channel inside the ball 11 passes through the ball valve body 1, and then the water inside the water inlet pipe 2 can flow to the water outlet at the other end of the ball valve body 1 through the channel inside the ball 11. When it is necessary to close the channel inside the ball valve body 1, the rotating rod 12 is turned to the right to drive the ball 11 to rotate to the right, so that the channel inside the ball 11 is separated from the water inlet at the middle end of the water inlet pipe 2, so that the water can only stay inside the water inlet pipe 2 and cannot enter the ball valve body 1. Then, the channel inside the ball valve body 1 can be controlled to open and close by simply rotating the rotating rod 12;

[0036] At the same time, when it is necessary to adjust the opening and closing of the channel inside the ball 11, the adjusting handle 15 at the upper end of the rotating rod 12 is rotated, and the fixing groove 16 opened at one end of the adjusting handle 15 is fixedly connected to the rotating rod 12, so that the adjusting handle 15 rotates to drive the rotating rod 12 to rotate, and the rotating rod 12 rotates to drive the ball 11 at the lower end to rotate. By rotating the ball 11, the channel inside the ball valve body 1 is opened and closed, so that the channel can be closed in time to avoid water overflow when water is not needed to flow through the channel.

[0037] In the specific adjustment process;

[0038] The user's operation steps are:

[0039] S1. By rotating the rotating rod 12 at the upper end of the ball 11, when the rotating rod 12 is rotated to the left, the ball 11 is driven to rotate to the left so that the channel inside the ball 11 is connected to the water inlet at the middle end of the water inlet pipe 2, so that the channel inside the ball 11 passes through the ball valve body 1, and then the water inside the water inlet pipe 2 can flow to the other end of the ball valve body 1 through the channel inside the ball 11;

[0040] S2. When water enters the water inlet pipe 2 and flows into the ball valve body 1, the water flowing inside the water inlet pipe 2 is filtered by the filter 6 installed in the combination bar 3 inside the water inlet pipe 2, so that all impurities in the water are filtered out and do not enter the ball valve body 1, thereby preventing the impurities in the water from corroding the ball valve body 1. When too many impurities accumulate inside the filter 6 and the filter 6 needs to be replaced, the lifting rod 9 at the middle end of the filter 6 is pulled out of the water inlet pipe 2. After the lifting rod 9 is pulled out, a new filter 6 is pushed into the water inlet pipe 2.

[0041] S3. When it is necessary to close the passage inside the ball valve body 1, the ball 11 is driven to rotate to the right by turning the rotating rod 12 to the right, so that the passage inside the ball 11 is separated from the water inlet at the middle end of the water inlet pipe 2, so that water can only stay inside the water inlet pipe 2 and cannot enter the ball valve body 1.

[0042] By adopting the above technical solutions:

[0043] The above design drives the ball 11 to rotate by rotating the rotating rod 12 at the upper end of the ball 11. When the rotating rod 12 is turned to the left, the ball 11 is driven to rotate to the left so that the channel inside the ball 11 is connected to the water inlet at the middle end of the water inlet pipe 2, so that the channel inside the ball 11 passes through the ball valve body 1, and then the water inside the water inlet pipe 2 can flow to the other end of the ball valve body 1 through the channel inside the ball 11. When it is necessary to close the channel inside the ball valve body 1, the ball 11 is driven to rotate to the right by turning the rotating rod 12 to the right, so that the channel inside the ball 11 is separated from the water inlet at the middle end of the water inlet pipe 2, so that the water can only stay inside the water inlet pipe 2 and cannot enter the inside of the ball valve body 1.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments.
