Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment, in particular to a regulating device and a hot water device. Background Art

[0002] In order to better control the water temperature of the water heater, a water regulating valve is generally provided in the water heater, and the water flow size of each water channel in the water heater is changed by the water regulating valve, so as to control the mixing ratio of cold and hot water to output a stable water temperature. In the prior art, a water regulating valve generally has a plug in the water channel, and the plug cooperates with the interception part in the water channel to control the size of the water flow. However, the prior art water regulating valve has the problem of sudden flow change during the valve opening process, which will cause a large disturbance to the water temperature, thereby reducing the user experience.

[0003] This is because: the plug in the prior art generally directly abuts against the interception part to play a interception role. Although the plug and the waterway are gradually set to control the water flow, when the plug is just separated from the interception part, the gap between the plug and the interception part is small, resulting in less water flow. When the plug gradually moves away from the interception part, the flow gap area between the plug and the interception part will increase by multiple times, which significantly increases the difficulty of designing and manufacturing the plug and the waterway size, making it difficult for the flow gap area between the plug and the waterway to change linearly. Therefore, when the plug is gradually removed from the interception part, the flow in the waterway will change greatly from zero to something, thereby reducing the flow regulation accuracy of the regulating valve. Therefore, how to improve the flow regulation accuracy of the regulating valve has become a technical problem that needs to be solved urgently. Utility Model Content

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] Implementation Method 1

[0045] Please refer to Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a regulating device, which comprises at least a shell 100, a blocking piece 200 and a flow structure 300, wherein the shell 100 comprises a medium flow channel 110; the blocking piece 200 is slidably disposed in the medium flow channel 110; the flow structure 300 is disposed on the blocking piece 200 and can be connected to the medium flow channel 110; the blocking piece 200 has a first position, a second position and a flow adjustment section in the medium flow channel 110; when the blocking piece 200 is in the first position, the medium flow channel 110 is completely blocked; when the blocking piece 200 is in the second position, the medium flow channel 110 is completely opened; when the blocking piece 200 is in the flow adjustment section, the effective flow area of ​​the flow structure 300 changes with the action of the blocking piece 200.

[0046] On the whole, when the regulating device is used, the fluid medium can be transported through the medium flow channel 110 provided in the housing 100, thereby meeting the fluid transportation needs. In addition, a blocking member 200 is also provided in the medium flow channel 110. When the blocking member 200 is in the first position, the blocking member 200 can completely block the medium flow channel 110, thereby playing a role of intercepting the flow. When the blocking member 200 is in the second position, the blocking member 200 can completely open the medium flow channel 110, thereby maximizing the conduction of the fluid medium. In addition, when the blocking member 200 is in the flow adjustment section between the first position and the second position, the blocking member 200 can adjust the size of the flow gap area between the blocking member 200 and the medium flow channel 110 through action, thereby playing a role of controlling the flow rate.

[0047] Since the flow gap area between the plugging piece and the medium flow channel in the prior art will change exponentially, the design and manufacturing difficulty is increased. In order to solve the above problem, the utility model is further provided with a flow structure 300 on the plugging piece 200. When the plugging piece 200 is in the flow adjustment section between the first position and the second position, the effective flow area of ​​the flow structure 300 can change with the action of the plugging piece 200, so that the flow gap area between the plugging piece 200 and the medium flow channel 110 can be adjusted by using the flow structure 300, so that the flow gap area can change roughly linearly, so as to facilitate more accurate control of the flow size of the regulating device, which is conducive to improving the flow regulation accuracy of the regulating device.

[0048] In an embodiment of the utility model, along the direction from the first position to the second position, the effective flow area of ​​the flow structure 300 gradually increases with the movement of the blocking member 200, so that the effective flow area of ​​the flow structure 300 can be used to regulate the flow gap area between the blocking member 200 and the medium flow channel 110, thereby facilitating more linear control of the flow size of the regulating device.

[0049] Of course, designers can adjust the variation rule of the effective flow area of ​​the flow structure 300 according to actual use needs, and no specific limitation is made here.

[0050] In the implementation mode of the present utility model, Figure 1 and Figure 7 In the embodiment shown, the regulating device further comprises a moving mechanism 400, which is movably disposed in the housing 100, and the blocking member 200 is connected to the moving mechanism 400, and the moving mechanism 400 can drive the blocking member 200 to move so as to change the flow area of ​​the flow regulating section.

[0051] By utilizing the moving mechanism 400 , the blocking member 200 can be driven to move between the first position and the second position, thereby adjusting the flow rate in the medium flow channel 110 .

[0052] Preferably, the moving mechanism 400 performs reciprocating linear motion. Of course, in other feasible embodiments, the moving mechanism 400 can also be configured to move in a rotational, translational, swinging or a combination of multiple actions, which is not specifically limited here.

[0053] In an embodiment of the present invention, the moving mechanism 400 includes a transmission member 410 movably disposed on the housing 100 , one end of the transmission member 410 is used to be drivably connected to the driving device 600 , and the other end of the transmission member 410 is connected to the blocking member 200 .

[0054] Preferably, the driving device 600 is a motor, and the moving mechanism 400 is driven by the motor. The motor can drive the moving mechanism 400 to move by direct driving, or the motor can drive the moving mechanism 400 to move by indirect driving, which is not specifically limited here.

[0055] In one possible embodiment, if Figure 1 In the embodiment shown, the transmission member 410 includes a transmission screw 411, one end of which is connected to the blocking member 200, and the other end of which is connected to the motor through a transmission structure. In addition, a transmission screw sleeve 412 is provided in the housing 100, and the transmission screw 411 is threadedly connected to the transmission screw sleeve 412.

[0056] The motor can drive the transmission screw 411 to rotate, and then the threaded cooperation between the transmission screw sleeve 412 and the transmission screw 411 can push the transmission screw 411 to reciprocate in the medium flow channel 110, so that the transmission screw 411 can drive the blocking member 200 to switch between the first position and the second position.

[0057] In addition, a transmission sealing structure is provided between the transmission screw 411 and the transmission screw sleeve 412 to prevent leakage of the medium in the medium flow channel 110. Designers can adjust the specific structure of the transmission sealing structure, such as a sealing ring, etc., according to the use requirements, and no specific limitation is made here.

[0058] Furthermore, the motor is configured as a stepper motor. By using a stepper motor in combination with a threaded transmission method, the transmission accuracy of the transmission screw 411 is improved, so that the flow rate of the regulating device can be controlled more accurately.

[0059] Of course, in other feasible embodiments, designers can adjust the specific structure of the moving mechanism 400 according to usage requirements, and no specific limitation is made here.

[0060] When the blocking piece 200 is hard-connected with the moving mechanism 400, that is, when the blocking piece 200 is connected to the moving mechanism 400 by threaded connection, welding, clamping, bonding or bolting, it is easy to cause assembly tolerance in the position between the blocking piece 200 and the moving mechanism 400, or the blocking piece 200 is prone to assembly tolerance after long-term use, making it difficult to ensure that the blocking piece 200 effectively seals the medium flow channel 110 when it is in the first position, thereby reducing the control accuracy of the medium flow.

[0061] In order to solve the above problems, in the implementation mode of the present utility model, Figure 1 and Figure 7In the illustrated embodiment, the adjusting device further comprises an elastic member 500 , and the blocking member 200 is adjustably disposed on the moving mechanism 400 via the elastic member 500 .

[0062] Specifically, one end of the elastic member 500 is sleeved on the moving mechanism 400 and connected to the moving mechanism 400 , and the other end of the elastic member 500 is connected to the blocking member 200 , thereby realizing a soft connection between the moving mechanism 400 and the blocking member 200 using the elastic member 500 .

[0063] When the blocking member 200 reaches the first position, the elastic member 500 may be in a compressed state, so that the elastic force of the elastic member 500 is conducive to ensuring that the blocking member 200 completely blocks the medium flow channel 110, thereby achieving a better use effect.

[0064] Preferably, the elastic member 500 is a spring. Of course, the designer can adjust the specific structure of the elastic member 500 according to the use requirements, and no specific limitation is made here.

[0065] In the implementation mode of the present utility model, Figure 2 and Figure 3 In the illustrated embodiment, the blocking member 200 includes a front end 210 and a rear end 220 , and the flow-through structure 300 extends from the front end 210 to the rear end 220 and is disposed on the outer side wall of the blocking member 200 .

[0066] By setting the flow structure 300 on the outer wall of the sealing piece 200 and extending the flow structure 300 from the front end 210 to the rear end 220, on the one hand, it is convenient to process the flow structure 300, and on the other hand, it is convenient to control the flow area of ​​the flow structure 300 to play a regulating role, so that the flow gap area between the sealing piece 200 and the medium flow channel 110 can change roughly linearly, thereby facilitating more linear control of the flow size of the regulating device.

[0067] Of course, in other feasible embodiments, designers can adjust the location of the flow-through structure 300 according to usage requirements, and no specific limitation is made here.

[0068] In the implementation mode of the present utility model, Figure 4 In the illustrated embodiment, the sealing member 200 includes a plug body 230 , a first shut-off portion 240 annularly arranged on the plug body 230 , and a shut-off section 250 arranged between the front end 210 and the first shut-off portion 240 , and the flow-through structure 300 is arranged on the outer wall of the shut-off section 250 .

[0069] In a feasible embodiment, the plug body 230 is substantially cylindrical. The moving mechanism 400 includes a transmission screw 411 , and the plug body 230 is sleeved on one end of the transmission screw 411 and connected to the transmission screw 411 through an elastic member 500 .

[0070] Of course, in other feasible embodiments, designers can adjust the specific structure of the plug body 230 according to usage requirements, and no specific restrictions are made here.

[0071] Furthermore, the medium flow channel 110 also includes a second intercepting portion 120 arranged in the flow regulating section. The intercepting section 250 can be slidably inserted in the flow regulating section. When the blocking member 200 is in the first position, the first intercepting portion 240 is sealed against the second intercepting portion 120.

[0072] By using the first intercepting portion 240 and the second intercepting portion 120 to cooperate with each other, the medium flow channel 110 can be better sealed.

[0073] Furthermore, by slidably inserting the cut-off section 250 into the flow regulating section, the gap between the cut-off section 250 and the flow regulating section constitutes a flow gap. By changing the matching position between the cut-off section 250 and the regulating section, it is helpful to control the size of the flow gap area, thereby more accurately controlling the flow size of the regulating device.

[0074] In a feasible embodiment, along the direction from the rear end 220 to the front end 210 , the outer side wall of the intercepting section 250 is gradually contracted inwardly.

[0075] By gradually shrinking the outer wall of the intercepting section 250 inward, the intercepting section 250 has different radial dimensions, so that when the intercepting section 250 is inserted into the flow regulating section, different positions of the intercepting section 250 can form flow gap areas of different sizes with the regulating section, thereby playing a role in regulating the flow. The designer can adjust the size of the inward shrinkage of the intercepting section 250 according to the use requirements, and no specific limitation is made here.

[0076] Furthermore, by providing a flow-through structure 300 on the intercepting section 250, the flow-through structure 300 can regulate the flow gap area between the intercepting section 250 and the flow regulating section, so that the flow gap area can change approximately linearly, thereby facilitating more linear control of the flow size of the regulating device, which is beneficial to improving the flow regulation accuracy of the regulating device.

[0077] The designer can adjust the radial size of the flow regulating section according to the use requirements, and no specific limitation is made here. Preferably, the radial size of the regulating section does not change, and the size of the flow gap area is only controlled by the intercepting section 250, thereby reducing the difficulty of controlling the flow area.

[0078] In the implementation mode of the present utility model, Figure 1 , Figure 6 and Figure 7In the illustrated embodiment, the flow structure 300 includes a flow groove 310 disposed on the outer side wall of the intercepting section 250 , and the flow groove 310 extends from the front end 210 to the first intercepting portion 240 .

[0079] By setting the flow groove 310 on the outer wall of the intercepting section 250 and extending the flow groove 310 along the front end 210 toward the first intercepting portion 240, when the intercepting section 250 is inserted into the adjusting section, the effective flow area of ​​the flow groove 310 can adjust the size of the flow gap area between the intercepting section 250 and the adjusting section, so that the flow gap area between the intercepting section 250 and the adjusting section is adjusted from a multiplier change to a roughly linear change, thereby eliminating the problem of sudden flow changes, which is conducive to better controlling the flow size of the adjusting device and having better flow regulation accuracy.

[0080] Further, such as Figure 5 In the illustrated embodiment, a plurality of flow grooves 310 are provided, and a plurality of spacer rings of the flow grooves 310 are provided on the outer side wall of the intercepting section 250 .

[0081] By using multiple flow slots 310 to coordinately adjust the flow gap area between the intercepting section 250 and the adjusting section, it is convenient to better control the effective flow area of ​​the flow slots 310, and a better coordinated adjustment effect is achieved.

[0082] Furthermore, by providing a plurality of flow grooves 310 , the problem of stress concentration during processing of the blocking member 200 is avoided, thereby increasing the service life of the blocking member 200 .

[0083] Designers can adjust the number and arrangement of the flow slots 310 according to usage requirements. For example, the number of flow slots can be set to 2, 3, 4 or more, and no specific numerical value is limited here.

[0084] In the embodiment of the present utility model, along the direction from the rear end 220 to the front end 210, the variation rule of the cross-sectional area of ​​the flow channel 310 is: the cross-sectional area of ​​the flow channel 310 is gradually increased.

[0085] The cross section of the flow channel 310 may be gradually increased, and the cross section of the flow channel 310 may be linearly increased. Of course, the cross section of the flow channel 310 may be gradually increased, and the cross section of the flow channel 310 may be nonlinearly increased, which is not specifically limited here.

[0086] In a specific embodiment, one end of the flow channel 310 is disposed close to the rear end 220 , and the cross-sectional area of ​​the end of the flow channel 310 close to the rear end 220 may be zero.

[0087] Furthermore, the other end of the flow slot 310 may penetrate the end surface where the front end 210 is located. Of course, the other end of the flow slot 310 may not penetrate the end surface where the front end 210 is located, and no specific limitation is made here.

[0088] Of course, designers can also adjust the cross-sectional area of ​​the end of the flow channel 310 near the rear end 220 to make it non-zero according to usage needs, and no specific limitation is made here.

[0089] The designer can adjust the specific size of each flow slot 310 according to the use requirements, and no specific numerical limit is made here. Among them, when there are multiple flow slots 310, each flow slot 310 can be set to the same size, or each flow slot 310 can also be set to different sizes, and no specific limit is made here.

[0090] In the embodiment of the present utility model, the first intercepting portion 240 includes a sealing member 241 , and the sealing member 241 is disposed on the blocking member 200 .

[0091] By arranging the sealing member 241 on the blocking member 200 , when the blocking member 200 is in the first position, the sealing member 241 can seal against the second intercepting portion 120 , thereby achieving a better sealing and intercepting effect.

[0092] Designers can adjust the specific structure of the sealing member 241 according to usage requirements. For example, the sealing member 241 includes a sealing ring disposed on the blocking member 200, and no specific limitation is made here.

[0093] Furthermore, the adjustment device also includes a stopper 260 disposed on the blocking member 200, and at least a portion of the stopper 260 is spaced apart from the blocking member 200 to form a mounting groove, and the sealing member 241 is detachably disposed in the mounting groove.

[0094] By arranging the stopper 260 on the blocking member 200 , the stopper 260 can cooperate with the outer wall of the blocking member 200 to form a mounting groove, and the sealing member 241 is arranged in the mounting groove, so that the sealing member 241 has better installation stability.

[0095] Furthermore, when the seal 241 is damaged, it is convenient to remove the seal 241 from the installation groove for replacement, thereby achieving better maintenance efficiency.

[0096] Specifically, the stopper 260 includes a stopper plate, which is disposed on the blocking member 200. The stopper plate is folded so that one end of the stopper plate covers the blocking member 200, and the other end of the stopper plate is spaced from the blocking member 200 to form the installation groove. The notch of the installation groove is disposed toward the second intercepting portion 120, so that the side wall of the sealing member 241 can be sealed against the second intercepting portion 120.

[0097] Of course, in other feasible embodiments, designers can adjust the specific structure of the stopper 260 according to usage requirements, and no specific limitation is made here.

[0098] In an embodiment of the present invention, the second intercepting portion 120 includes an intercepting platform 121 , which is disposed in a ring in the medium flow channel 110 . When the blocking member 200 is in the first position, the intercepting platform 121 is in sealing contact with the sealing member 241 .

[0099] Preferably, the intercepting platform 121 is annular and convexly disposed on the inner wall of the medium flow channel 110, and the intercepting platform 121 has a side portion that abuts against the sealing member 241. By annularly disposing the intercepting platform 121 in the medium flow channel 110, the intercepting platform 121 can better cooperate with the sealing member 241 to seal the medium flow channel 110.

[0100] Of course, in other feasible embodiments, designers can adjust the specific structure of the intercepting platform 121 according to usage requirements, and no specific limitation is made here.
