Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, and more specifically, to a ball pipe with a flow-blocking portion. Background Art

[0002] PE pipes are widely used in urban construction, and their layout and installation rely on fittings to connect them. Among these fittings, ball joints are commonly used to connect multiple pipes. Compared to ordinary connecting pieces, ball joints, thanks to their spherical structure, can withstand greater pressure and have a longer service life. However, when water flows through ball joints, centrifugal force often causes it to swirl along the inner wall of the joint, slowing the flow rate and hindering drainage.

[0003] A Chinese patent discloses a three-way ball valve, comprising a valve body, an inner valve, and a choke valve. The inner valve further comprises a first shaft, wherein the inner valve and the choke valve can rotate about the axis of the first shaft. The inner valve further comprises a slide rail disposed within the inner valve, along which the choke valve can slide. The inner valve further comprises a first valve port and a second valve port, and the choke valve can close the second valve port. The valve body of the utility model comprises an inner valve and a choke valve, wherein the inner valve is provided with a slide rail, along which the choke valve can slide. When the choke valve is completely within the slide rail, the choke valve does not affect the flow-guiding function of the three-way ball valve, and fluid can pass through the first and second valve ports. When the choke valve slides along the slide rail to close the second valve port, fluid cannot pass through the second valve port. The three-way ball valve can achieve flow interception using a single three-way ball valve. However, when water flows into the ball valve, it rotates on the inner wall of the ball valve, forming a vortex, and is retained within the ball valve due to centrifugal force, reducing drainage efficiency. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a ball pipe with a flow-blocking portion, which can prevent water from forming vortices inside the ball pipe and reduce the retention time of water in the ball pipe.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A ball pipe with a flow blocking portion is provided, comprising a ball shell, a first passage and a second passage, wherein the first passage and the second passage are both connected to the interior of the ball shell, and a flow blocking portion is further provided on the inner wall of the ball shell, wherein the flow blocking portion is used to prevent water from rotating counterclockwise in the ball shell.

[0007] Through this arrangement, when water flows into the spherical shell from the first passage, the water flow is affected by centrifugal force, rotates along the inner wall of the spherical shell, and forms a vortex in the spherical shell. At this time, the blocking part interferes with the rotation of the vortex and guides the water flow downward. The water flow flows out from the second passage under the guidance of the blocking part, thereby reducing the residence time of the water flow in the spherical shell, which is conducive to improving drainage efficiency.

[0008] Preferably, the flow blocking portion includes a plurality of first flow blocking ribs and second flow blocking ribs, the first flow blocking ribs are all installed on the upper part of the inner wall of the spherical shell, and the second flow blocking ribs are all installed on the lower part of the inner wall of the spherical shell.

[0009] Preferably, the first blocking rib extends from the middle of the spherical shell to the top of the spherical shell, and the second blocking rib extends from the middle of the spherical shell to the bottom of the spherical shell.

[0010] Through this arrangement, when water flows into the ball tube, it rotates under the action of centrifugal force to form a vortex. During the rotation of the vortex, it impacts the first and second baffle ribs, reducing the rotational inertia of the vortex; and part of the water flows to the bottom under the guidance of the first and second baffle ribs, thereby reducing the rotation time of the water flow in the ball tube, increasing the water discharge speed, and improving the drainage efficiency.

[0011] Preferably, the first flow-blocking rib and the second flow-blocking rib are both arc-shaped strip structures, and the arc-shaped protruding direction of the first flow-blocking rib is opposite to the arc-shaped protruding direction of the second flow-blocking rib.

[0012] Preferably, the projection of the first blocking ribs in the first direction is arranged in a counterclockwise spiral direction.

[0013] With this setting, in the northern hemisphere, due to the Coriolis force, the vortex formed by the water flow will rotate counterclockwise, and the first flow-blocking rib has a counterclockwise spiral arc, which is the same as the direction of the vortex. The vortex located at the upper part of the spherical shell will flow into the lower part of the spherical tube along the direction of the first flow-blocking rib.

[0014] Preferably, projections of the plurality of second flow-blocking ribs in the first direction are arranged in a clockwise spiral direction.

[0015] Through this arrangement, a counterclockwise vortex will be formed in the water flow in the northern hemisphere. When the vortex enters the bottom of the spherical shell, the rotation direction of the vortex is opposite to the curvature direction of the second baffle rib. The vortex is strongly disturbed by the second baffle rib and cannot maintain rotation. It flows into the second passage under the action of gravity. The curvature directions of the first baffle rib and the second baffle rib are opposite, which is conducive to further expanding the disturbing effect on the water flow rotation and improving the drainage efficiency.

[0016] Preferably, a plurality of the first flow-blocking ribs are evenly distributed on the upper portion of the inner wall of the spherical shell, and a plurality of the second flow-blocking ribs are evenly distributed on the lower portion of the inner wall of the spherical shell.

[0017] Through this arrangement, the first baffle rib and the second baffle rib are evenly distributed inside the spherical shell, continuously blocking the rotation of the vortex during its rotation, thereby continuously weakening the centrifugal force of the vortex and reducing the residence time of the vortex in the spherical shell.

[0018] Preferably, the first passage is arranged beside the spherical shell, the second passage is arranged at the bottom of the spherical shell, the axial direction of the second passage is parallel to the first direction, and the axial directions of the first passage and the second passage are perpendicular to each other.

[0019] With this arrangement, when water flows into the spherical shell from the first passage, the vortex formed by the water flow is weakened by the flow resistance part inside the spherical shell and flows downward into the second passage, which is beneficial to improving the drainage efficiency of the waterway.

[0020] Preferably, a third passage and a fourth passage are further included, both of which are connected to the spherical shell, the third passage is coaxially arranged with the axial direction of the first passage, and the fourth passage is coaxially arranged with the axial direction of the second passage.

[0021] Through this arrangement, a four-way ball channel is formed. After the water flows into the spherical shell from any channel, it can be blocked by the flow blocking part, which reduces the duration of the vortex and improves the drainage efficiency. On the other hand, when the water flow is oscillated inside the spherical shell by the flow blocking part, it is conducive to the discharge of gas in the water flow. The spherical ball channel is conducive to the upward discharge of gas. The gas can be discharged from the fourth channel and can also play a role in gas-liquid separation.

[0022] Preferably, it further includes a fifth passage and a sixth passage, both of which are connected to the interior of the spherical shell, the axial direction of the fifth passage is coaxial with the axial direction of the sixth passage, and the axial directions of the first passage, the second passage and the fifth passage are perpendicular to each other.

[0023] Through this setting method, a six-way ball pass is formed, and the number of pipes that can be connected to the ball pass is greatly increased. After the water flow enters the ball pass from any passage, it can be affected by the flow resistance part inside the ball shell, reducing the residence time of the vortex in the ball shell, which is beneficial to improving drainage efficiency.

[0024] Preferably, the first passage, the second passage, the third passage, the fourth passage, the fifth passage and the sixth passage are all provided with detachably connected blocking covers.

[0025] Through this setting method, users can remove the blocking cover of the corresponding passage as needed, and the other unremoved blocking covers lock the passage to prevent leakage, so that the ball pass can be flexibly used in two-way, three-way, four-way, five-way or six-way occasions in different directions, greatly improving the scope of use of the ball pass.

[0026] Preferably, the first passage, the second passage, the third passage, the fourth passage, the fifth passage and the sixth passage are all provided with external threads on the outside, the blocking cover is provided with internal threads on the inside, and the blocking cover is also provided with a waterproof ring on the inside, and the blocking cover is threadedly connected to the first passage, the second passage, the third passage, the fourth passage, the fifth passage and the sixth passage.

[0027] Through this setting method, the threaded connection can ensure that the blocking cover is tightly connected to each passage, preventing the blocking cover from falling off when the water pressure is high; on the other hand, when the blocking cover is connected to each passage, the waterproof ring inside the blocking cover abuts against the end of each passage, filling the connection gap between the blocking cover and each passage, reducing the probability of leakage, and helping to improve the reliability of the ball pass.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] (1) The setting of the flow-blocking part prevents the water flow from rotating in the ball to form a vortex, thereby reducing the residence time of the water flow in the ball shell and improving the drainage efficiency.

[0030] (2) By setting the first and second flow-blocking ribs, water is guided to flow toward the bottom of the spherical shell, which is beneficial to improving drainage efficiency.

[0031] (3) By setting the blocking cover, the number and direction of the ball pass can be flexibly adjusted according to the usage scenario, thereby improving the applicability of the ball pass. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1

[0042] like Figures 1 to 4 The figure shows a first embodiment of a ball pipe with a flow blocking portion of the present invention, comprising a ball shell 1, a first passage 2 and a second passage 3. The first passage 2 and the second passage 3 are both connected to the interior of the ball shell 1. A flow blocking portion 4 is further provided on the inner wall of the ball shell 1. The flow blocking portion 4 is used to prevent the water flow from rotating counterclockwise in the ball shell 1.

[0043] Through this arrangement, when the water flows into the spherical shell 1 from the first passage 2, the water flow is subjected to the centrifugal force, rotates along the inner wall of the spherical shell 1, and forms a vortex in the spherical shell 1. At this time, the flow-blocking part 4 interferes with the rotation of the vortex and guides the water flow to move downward. Under the guidance of the flow-blocking part 4, the water flow flows out from the second passage 3, thereby reducing the residence time of the water flow in the spherical shell, which is conducive to improving the drainage efficiency.

[0044] As an embodiment of the present invention, the flow blocking portion 4 includes a plurality of first flow blocking ribs 41 and second flow blocking ribs 42 . The first flow blocking ribs 41 are all installed on the upper portion of the inner wall of the spherical shell 1 , and the second flow blocking ribs 42 are all installed on the lower portion of the inner wall of the spherical shell 1 .

[0045] Preferably, the first blocking rib 41 extends from the middle of the spherical shell 1 to the top of the spherical shell 1 , and the second blocking rib 42 extends from the middle of the spherical shell 1 to the bottom of the spherical shell 1 .

[0046] With this arrangement, when water flows into the ball tube, it rotates under the action of centrifugal force to form a vortex. During the rotation of the vortex, it impacts the first and second baffle ribs 41, 42, reducing the rotational inertia of the vortex. Moreover, part of the water flows toward the bottom under the guidance of the first and second baffle ribs 41, 42, thereby reducing the rotation time of the water flow in the ball tube, increasing the water discharge speed, and improving the drainage efficiency.

[0047] As an embodiment of the present invention, the first blocking rib 41 and the second blocking rib 42 are both arc-shaped strip structures, and the arc-shaped protruding direction of the first blocking rib 41 is opposite to the arc-shaped protruding direction of the second blocking rib 42 .

[0048] As an embodiment of the present invention, the projections of the plurality of first flow-blocking ribs 41 along the first direction in the spherical shell 1 are arranged in a counterclockwise spiral.

[0049] With this arrangement, in the northern hemisphere, due to the Coriolis force, the vortex formed by the water flow will rotate counterclockwise, and the first flow-blocking rib 41 has a counterclockwise spiral arc, which is the same as the direction of the vortex. The vortex located at the upper part of the spherical shell 1 will flow into the lower part of the ball tube along the direction of the first flow-blocking rib 41.

[0050] As an embodiment of the present invention, the projections of the plurality of second flow-blocking ribs 42 along the second direction in the spherical shell 1 are arranged spirally in a clockwise direction.

[0051] The second direction is opposite to the first direction. With this arrangement, water flow in the northern hemisphere will form a counterclockwise vortex. When the vortex enters the bottom of the spherical shell 1, the rotation direction of the vortex is opposite to the curvature direction of the second flow-blocking rib 42. The vortex is strongly disturbed by the second flow-blocking rib 42 and cannot maintain rotation. Instead, it flows into the second passage 3 under the action of gravity. The first flow-blocking rib 41 and the second flow-blocking rib 42 have opposite curvature directions, which is conducive to further amplifying the disturbance effect on the rotation of the water flow and improving drainage efficiency.

[0052] As an embodiment of the present invention, a plurality of first flow-blocking ribs 41 are evenly distributed on the upper portion of the inner wall of the spherical shell 1 , and a plurality of second flow-blocking ribs 42 are evenly distributed on the lower portion of the inner wall of the spherical shell 1 .

[0053] Through this arrangement, the first blocking rib 41 and the second blocking rib 42 are evenly distributed inside the spherical shell 1, and continuously block the rotation of the vortex during its rotation, so that the centrifugal force of the vortex is continuously weakened, reducing the residence time of the vortex in the spherical shell 1.

[0054] As an embodiment of the present invention, the first passage 2 is installed beside the spherical shell 1, and the second passage 3 is installed at the bottom of the spherical shell 1. The axial direction of the second passage 3 is parallel to the first direction, and the axial directions of the first passage 2 and the second passage 3 are perpendicular to each other.

[0055] With this arrangement, when water flows into the spherical shell 1 from the first passage 2, the vortex formed by the water flow is weakened by the flow resistance part 4 inside the spherical shell 1, and then flows downward into the second passage 3, which is beneficial to improving the drainage efficiency of the waterway.

[0056] Example 2

[0057] like Figure 5 The second embodiment of the ball pass with a flow-blocking portion of the present invention is shown. This embodiment is similar to the first embodiment, except that it further includes a third passage 5 , a fourth passage 6 , a fifth passage 7 and a sixth passage 8 .

[0058] As an embodiment of the present invention, it also includes a third passage 5 and a fourth passage 6, both of which are connected to the spherical shell 1, the third passage 5 is coaxially arranged with the axial direction of the first passage 2, and the axial direction of the fourth passage 6 is coaxially arranged with the axial direction of the second passage 3.

[0059] Through this arrangement, a four-way ball channel is formed. After the water flows into the spherical shell 1 from any channel, it can be blocked by the flow blocking part 4, which reduces the duration of the vortex and improves the drainage efficiency. On the other hand, when the water flow is oscillated by the flow blocking part 4 inside the spherical shell 1, it is beneficial to discharge the gas in the water flow. The spherical ball channel is conducive to the upward discharge of the gas. The gas can be discharged from the fourth channel 6 and can also play a role in gas-liquid separation.

[0060] As an embodiment of the present invention, it also includes a fifth passage 7 and a sixth passage 8. The fifth passage 7 and the sixth passage 8 are both connected to the interior of the spherical shell 1. The axial direction of the fifth passage 7 is coaxial with the axial direction of the sixth passage 8. The axial directions of the first passage 2, the second passage 3 and the fifth passage 7 are perpendicular to each other.

[0061] Through this setting, a six-way ball pass is formed, and the number of pipes that can be connected to the ball pass is greatly increased. After the water flows into the ball pass from any passage, it can be affected by the flow resistance part 4 in the ball shell 1, reducing the residence time of the vortex in the ball shell 1, which is conducive to improving the drainage efficiency.

[0062] Example 3

[0063] like Figure 5 The third embodiment of the ball valve with a flow-blocking portion of the present invention is shown. This embodiment is similar to the first embodiment, except that it further includes a blocking cover 9 .

[0064] As an embodiment of the present invention, the first passage 2 , the second passage 3 , the third passage 5 , the fourth passage 6 , the fifth passage 7 and the sixth passage 8 are all provided with a detachably connected blocking cover 9 .

[0065] Through this setting, the user can remove the blocking cover 9 of the corresponding passage as needed, and the other unremoved blocking covers 9 lock the passage to prevent leakage, so that the ball pass can be flexibly used in two-way, three-way, four-way, five-way or six-way occasions in different directions, greatly improving the scope of use of the ball pass.

[0066] As an embodiment of the present utility model, the first passage 2, the second passage 3, the third passage 5, the fourth passage 6, the fifth passage 7 and the sixth passage 8 are all provided with external threads on the outside, the blocking cover 9 is provided with internal threads on the inside, and the blocking cover 9 is also provided with a waterproof ring on the inside. The blocking cover 9 is threadedly connected to the first passage 2, the second passage 3, the third passage 5, the fourth passage 6, the fifth passage 7 and the sixth passage 8.

[0067] Through this setting method, the threaded connection can ensure that the blocking cover 9 is tightly connected to each passage, preventing the blocking cover 9 from falling off when the water pressure is high; on the other hand, when the blocking cover 9 is connected to each passage, the waterproof ring inside the blocking cover 9 abuts against the end of each passage, filling the connection gap between the blocking cover 9 and each passage, reducing the probability of leakage, and helping to improve the reliability of the ball pass.
