Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to a rotating shaft tube type multi-way valve. Background Art

[0002] Multi-way valves are widely used in various technical fields in various forms to control complex fluid flows in various needs. Multi-way valves can replace the combination of multiple one-way valves. Especially in the field of new energy vehicles, as people's requirements for riding comfort and vehicle performance continue to increase, the replacement of vehicle fluid circuit technology has become more complicated.

[0014] Furthermore, the obtuse-angled plates at the top and bottom are rotatably connected to a rotating plate on one side away from the fan shaft, one end of the rotating plate away from the obtuse-angled plate is rotatably connected to the inner wall of the square groove, the side of the rotating plate close to the one-way tube is fixedly connected to a rubber block, and the side of the rotating plate close to the one-way tube is fixedly connected to two rubber layers.

[0015] Furthermore, a rotating mechanism is provided on the outer surface of the fan shaft, and the rotating mechanism includes a plurality of flexible belts fixedly connected to the side of the cylindrical sleeve close to the obtuse plate, and one end of the flexible belt away from the cylindrical sleeve is fixedly connected to the side wall of the obtuse plate.

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention designs the valve column of the multi-way valve into an inner and outer layer structure, which is connected with the square groove on the valve housing through the channel of the valve column, so as to switch the thermal management mode required by the whole vehicle system. The function that originally required three multi-way valves can be realized by using one multi-way valve of the present invention, and more working modes can be realized with fewer valve housing ports. In this way, the overall volume of the multi-way valve is smaller, which can save more space.

[0019] 2. In the present invention, when the fluid enters the channel opened on the valve column through the square groove, the fluid inside the channel will squeeze the one-way plate, and the one-way plate will rotate toward the inside of the air inlet groove after being squeezed, and then the fluid inside the channel will enter the flexible bag. When the gas enters the channel, it will squeeze the flexible bag, so that the flexible bag flows outward in the air inlet groove and expands at the same time. When the flexible bag expands outward, the expansion of the flexible bag will squeeze the hollow frame through the flexible layer to slide inside the auxiliary groove. When the flexible layer is squeezed and moves, the outer wall of the flexible layer close to the square groove will separate from the connecting groove. At this time, when the flexible bag expands and squeezes the flexible layer, the flexible bag will It fits tightly with the flexible layer, so that the channel and the square groove can be sealed, reducing leakage between the channel and the square groove during operation. When leakage occurs between the flexible bag and the flexible layer of this device under long-term operation, the leaked fluid will enter the front of the hollow frame through the connecting groove. At this time, the fluid entering the front of the hollow frame will provide a driving force to the hollow frame toward the flexible layer. At this time, the hollow frame can enhance the sealing between the flexible layer and the flexible bag under the push of the fluid, reduce the mixing of fluids between multiple channels due to leakage, ensure that this device can operate stably under different working pressures, and reduce the occurrence of leakage.

[0020] 3. According to the present invention, when the fluid flows in the square groove toward the interior of the channel on the valve column, a part of the fluid will flow between the outside of the cylindrical sleeve and the rotating plate, and the other part of the fluid will flow inside the cylindrical sleeve. When the fluid inside the cylindrical sleeve flows, it will drive the fan shaft to rotate. At this time, the flow rate of the fluid inside and outside the cylindrical sleeve will change under the rotation of the fan shaft. At this time, the fluid inside and outside the cylindrical sleeve will flow outside and inside the flexible belt when flowing. When the flexible belt is affected by the flow of the internal and external fluids, it will shake up and down under the change of its flow rate. When the flexible belt shakes, it will drive the obtuse-angled plate to rotate up and down. When the obtuse-angled plate rotates, the rotation of the obtuse-angled plate will drive the rotating plate to rotate up and down. When the rotating plate rotates in the direction of the fan shaft, the rotation of the rotating plate will drive the rubber block to rotate synchronously. When the rotating plate drives the rubber block to rotate, it will drive The movable rubber block slides in the one-way tube. When the rubber block slides in the direction of the fan shaft in the one-way tube, the sliding of the rubber block will absorb the gas inside the one-way tube. When the rubber block slides in the one-way tube and absorbs the gas inside the one-way tube, the one-way valve inside the one-way tube will open. At this time, under the reciprocating rotation of the rotating plate, the rubber block will periodically extract the gas inside the hollow frame through the one-way tube to form a negative pressure area in the hollow frame. When negative pressure is formed in the hollow frame, the negative pressure inside the hollow frame will absorb the flexible bag in contact with the flexible layer through the circular hole, which can provide additional adsorption force for the seal between the valve shell and the valve cover. At the same time, the flexible layer and the flexible bag can be in closer contact through adsorption, which further enhances the overall sealing performance between the flexible layer and the flexible bag, and further improves the stability and reliability of the device.

[0021] 4. In the present invention, when the fluid flows inside the cylindrical sleeve, the flow of the fluid will impact the fan shaft and make it rotate. When the fan shaft rotates, the rotation of the fan shaft will drive the rotating frame to rotate synchronously. When the rotating frame rotates, it will rotate at the connection between the flexible bag and the flexible layer. When the rotating frame rotates, it will drive multiple wave plates to rotate synchronously. When the rotating frame drives the wave plates to rotate, the wave plates will rotate inside the fluid. At this time, when the wave plates rotate in the fluid, they will shake up and down with the rotation of the rotating frame under the resistance of the fluid. When the wave plates shake, they will disturb the fluid between the flexible layer and the flexible bag. When the fluid is disturbed, the flow intensity of the fluid between the flexible layer and the flexible bag can be reduced to a certain extent, reducing the risk of leakage or damage of the sealing layer caused by the impact of the fluid between the flexible layer and the flexible bag, thereby reducing the overall flow intensity and extending the sealing efficiency and service life of the sealing layer.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The valve column 201 of the multi-way valve is designed as an inner and outer layer structure, which is connected to the square groove 101 on the valve housing 1 through the channel of the valve column 201, and the thermal management mode required by the whole vehicle system is switched. The function that originally required three multi-way valves to be realized can be realized by using a multi-way valve of the present invention, and more working modes can be realized with fewer valve housing 1 ports. In this way, the overall volume of the multi-way valve is smaller, which can save more space.

[0039] Seven channels are provided on the outer surface of the valve column 201, which are channel one 204, channel two 205, channel three 206, channel four 207, channel five 208, channel six 209 and channel seven 210, respectively. When the fluid enters the channel on the valve column 201 through the square groove 101, the fluid inside the channel will squeeze the one-way plate 211. After being squeezed, the one-way plate 211 will rotate toward the inside of the air inlet groove, and then the fluid inside the channel will enter the flexible bag 203. When the gas enters the channel, it will squeeze the flexible bag 203, so that the flexible bag 203 will flow outward in the air inlet groove and expand at the same time.

[0040] An air inlet hole is provided on one side of the flexible bag 203 close to the channel. The air inlet hole on one side close to the valve cover 102 penetrates the bottom inner wall of the channel and extends to the inside. A one-way plate 211 is rotatably connected inside the air inlet hole. An inner channel 202 is provided inside the valve column 201.

[0041] The second channel 205 is connected to the sixth channel 209 through the inner channel 202 . When the flexible bag 203 expands outward, the expansion of the flexible bag 203 will squeeze the hollow frame 301 through the flexible layer 302 to slide inside the auxiliary groove 104 .

[0042] One end of the one-way tube 303 away from the hollow frame 301 penetrates to the side wall of the square groove 101, and the one-way tube 303 is connected to the hollow frame 301. A plurality of circular holes are provided on the top and bottom of the hollow frame 301, and one end of the plurality of circular holes away from the hollow frame 301 penetrates to the outer wall of the flexible layer 302. When leakage occurs between the flexible bag 203 and the flexible layer 302 during long-term operation of the device, the leaked fluid will enter the front of the hollow frame 301 through the connecting groove 105. At this time, the fluid entering the front of the hollow frame 301 will provide a driving force to the hollow frame 301 toward the side of the flexible layer 302.

[0043] An auxiliary mechanism 4 is provided inside the square groove 101, and the auxiliary mechanism 4 includes a cylindrical sleeve 401 fixedly connected to the inside of the square groove 101, and the inside of the cylindrical sleeve 401 is rotatably connected to a fan shaft 402, and the outer surface of the fan shaft 402 is rotatably connected to a plurality of obtuse-angled plates 403. When the fluid flows in the square groove 101 toward the inside of the channel on the valve column 201, a part of the fluid will flow between the outside of the cylindrical sleeve 401 and the rotating plate 404, and the other part of the fluid will flow inside the cylindrical sleeve 401. When the fluid inside the cylindrical sleeve 401 flows, it will drive the fan shaft 402 to rotate.

[0044] The obtuse-angled plates 403 at the top and bottom are rotatably connected to a rotating plate 404 on one side away from the fan shaft 402, and one end of the rotating plate 404 away from the obtuse-angled plates 403 is rotatably connected to the inner wall of the square groove 101, and a rubber block is fixedly connected to the side of the rotating plate 404 close to the one-way tube 303, and two rubber layers are fixedly connected to the side of the rotating plate 404 close to the one-way tube 303. At this time, the flow rate of the fluid inside and outside the cylindrical sleeve 401 will change under the rotation of the fan shaft 402, and at this time, the fluid inside and outside the cylindrical sleeve 401 will flow outside and inside the flexible belt 501 when flowing.

[0045] A rotating mechanism 5 is provided on the outer surface of the fan shaft 402, and the rotating mechanism 5 includes a plurality of flexible belts 501 fixedly connected to the side of the cylindrical sleeve 401 close to the obtuse-angled plate 403, and one end of the flexible belt 501 away from the cylindrical sleeve 401 is fixedly connected to the side wall of the obtuse-angled plate 403. When the fluid flows inside the cylindrical sleeve 401, the flow of the fluid will impact the fan shaft 402 and cause it to rotate. When the fan shaft 402 rotates, the rotation of the fan shaft 402 will drive the rotating frame 502 to rotate synchronously. When the rotating frame 502 rotates, it will rotate at the connection between the flexible bag 203 and the flexible layer 302.

[0046] A rotating frame 502 is provided on one side of the several flexible belts 501 close to the obtuse-angled plate 403, and the side of the rotating frame 502 close to the fan shaft 402 is fixedly connected to the fan shaft 402. The outer surface of the rotating frame 502 is rotatably connected to several wave plates 503. When the rotating frame 502 rotates, it will drive multiple wave plates 503 to rotate synchronously. When the rotating frame 502 drives the wave plates 503 to rotate, the wave plates 503 will rotate inside the fluid. At this time, when the wave plates 503 rotate in the fluid, they will swing up and down under the resistance of the fluid as the rotating frame 502 rotates. When the wave plates 503 swing, they will disturb the fluid between the flexible layer 302 and the flexible bag 203.

[0047] When in use, the device is first installed with the corresponding equipment, and then the square groove (101) is connected to the external pipeline, and then the actuator (103) is turned on. When it is necessary to switch the external fluid, the actuator (103) is started. When the actuator (103) works, it drives the valve column (201) to rotate. When the valve column (201) rotates, it drives several channels on the surface to correspond to the square groove (101), thereby completing the switching of the fluid.

[0048] The valve column 201 of the multi-way valve is designed to be an inner and outer layer structure, which is connected to the square groove 101 on the valve housing 1 through the channel of the valve column 201, so as to switch the thermal management mode required by the whole vehicle system. The function that originally required three multi-way valves can be realized by using one multi-way valve of the present invention, and more working modes can be realized with fewer valve housing 1 ports. In this way, the overall volume of the multi-way valve is smaller, which can save more space.

[0049] When the fluid enters the channel opened on the valve column 201 through the square groove 101, the fluid inside the channel will squeeze the one-way plate 211. After being squeezed, the one-way plate 211 will rotate toward the inside of the air inlet groove, and then the fluid inside the channel will enter the flexible bag 203. When the gas enters the channel, it will squeeze the flexible bag 203, so that the flexible bag 203 flows outward in the air inlet groove and expands at the same time. When the flexible bag 203 expands outward, the expansion of the flexible bag 203 will squeeze the hollow frame 301 through the flexible layer 302 to slide inside the auxiliary groove 104. When the flexible layer 302 is squeezed and moves, the outer wall of the flexible layer 302 on one side close to the square groove 101 will separate from the connecting groove 105. At this time, when the flexible bag 203 expands and squeezes the flexible layer 302, the flexible bag 203 will expand and squeeze the flexible layer 302. The flexible bag 203 will fit tightly with the flexible layer 302, so as to seal the channel and the square groove 101, reducing leakage between the channel and the square groove 101 during operation. When leakage occurs between the flexible bag 203 and the flexible layer 302 during long-term operation of the device, the leaked fluid will enter the front of the hollow frame 301 through the connecting groove 105. At this time, the fluid entering the front of the hollow frame 301 will provide a driving force to the hollow frame 301 toward the side of the flexible layer 302. At this time, the hollow frame 301 can enhance the sealing between the flexible layer 302 and the flexible bag 203 under the push of the fluid, reduce the mixing of fluids between multiple channels due to leakage, ensure that the device can operate stably under different working pressures, and reduce the occurrence of leakage.

[0050] When the fluid flows in the square groove 101 toward the inner part of the channel on the valve column 201, a part of the fluid will flow between the outside of the cylindrical sleeve 401 and the rotating plate 404, and the other part of the fluid will flow inside the cylindrical sleeve 401. When the fluid inside the cylindrical sleeve 401 flows, it will drive the fan shaft 402 to rotate. At this time, the flow rate of the fluid inside and outside the cylindrical sleeve 401 will change under the rotation of the fan shaft 402. At this time, the fluid inside and outside the cylindrical sleeve 401 will flow between the outside of the flexible belt 501 and the rotating plate 404. When the flexible belt 501 is affected by the flow of the internal and external fluids, it will shake up and down under the change of the flow rate. When the flexible belt 501 shakes, it will drive the obtuse angle plate 403 to rotate up and down. When the obtuse angle plate 403 rotates, the rotation of the obtuse angle plate 403 will drive the rotating plate 404 to rotate up and down. When the rotating plate 404 rotates in the direction of the fan shaft 402, the rotation of the rotating plate 404 will drive the rubber block to rotate synchronously. When the rotating plate 404 drives the rubber block to rotate, it will drive the rubber The rubber block slides in the one-way tube 303. When the rubber block slides in the direction of the fan shaft 402 in the one-way tube 303, the sliding of the rubber block will absorb the gas inside the one-way tube 303. When the rubber block slides in the one-way tube 303 and absorbs the gas inside the one-way tube 303, the one-way valve inside the one-way tube 303 will open. At this time, under the reciprocating rotation of the rotating plate 404, the rubber block will periodically extract the gas inside the hollow frame 301 through the one-way tube 303, so that the hollow frame 301 is 1 forms a negative pressure area. When negative pressure is formed in the hollow frame 301, the negative pressure inside the hollow frame 301 will adsorb the flexible bag 203 in contact with the flexible layer 302 through the circular hole, which can provide additional adsorption force for the seal between the valve housing 1 and the valve cover 102. At the same time, the flexible layer 302 and the flexible bag 203 can be in closer contact through adsorption, which further enhances the overall sealing performance between the flexible layer 302 and the flexible bag 203, and further improves the stability and reliability of the device.

[0051] When the fluid flows inside the cylindrical sleeve 401, the flow of the fluid will impact the fan shaft 402 and make it rotate. When the fan shaft 402 rotates, the rotation of the fan shaft 402 will drive the rotating frame 502 to rotate synchronously. When the rotating frame 502 rotates, it will rotate at the connection between the flexible bag 203 and the flexible layer 302. When the rotating frame 502 rotates, it will drive multiple wave plates 503 to rotate synchronously. When the rotating frame 502 drives the wave plates 503 to rotate, the wave plates 503 will rotate inside the fluid. At this time, the wave plates 503 are in the fluid. When rotating internally, it will rock up and down with the rotation of the rotating frame 502 under the resistance of the fluid. When the wave plate 503 rocks, it will disturb the fluid between the flexible layer 302 and the flexible bag 203. When the fluid is disturbed, the flow intensity of the fluid between the flexible layer 302 and the flexible bag 203 can be reduced to a certain extent, and the risk of leakage or damage of the sealing layer caused by the impact of the fluid between the flexible layer 302 and the flexible bag 203 can be reduced, thereby reducing the overall flow intensity and extending the sealing efficiency and service life of the sealing layer.
