Abstract

The application discloses a steady flow valve and a water heater comprising the same. The steady flow valve comprises a first moving part and a second moving part. The first moving part comprises a first shielding part and a first channel. The second moving part comprises a second shielding part and a second channel. The first moving part and the second moving part are arranged to reversely rotate around the axis of the flow passage when the valve core assembly of the steady flow valve moves along the axial direction of the flow passage of the valve body of the steady flow valve. When the valve core moves from the first position to the second position, the area of the first channel and the second channel overlapping in the axial direction of the flow passage decreases. When the valve core moves from the second position to the first position, the area of the first channel and the second channel overlapping in the axial direction of the flow passage increases. Since the first moving part and the second moving part are reversely rotated, the overlapping area of the first channel and the second channel can be quickly adjusted, that is, the opening of the steady flow valve can be quickly adjusted, and the response speed of the steady flow valve is improved, so that the steady flow valve can timely play the role of stabilizing the flow.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of water heaters, in particular to a steady flow valve and a water heater comprising the same. BACKGROUND

[0002] In a waterway system, in order to make the fluid flow smoothly in one direction, a check valve or a steady flow valve or a throttle valve is often arranged. Arranging a water flow stabilizing device in the waterway system of a gas water heater can effectively improve the problem of water temperature fluctuation caused by water flow fluctuation, and improve the user experience of using the gas water heater. With the increasing number of high-rise buildings, the water pressure situation of users' homes is becoming more and more complex. Some communities have high water pressure and large water pressure fluctuation, which brings certain difficulties to the use of existing gas water heaters. Developing a steady flow device with simple structure and reliability can effectively solve the problem of large water temperature fluctuation of the gas water heater in high water pressure areas.

[0003] The steady flow valve in the prior art basically realizes the flow regulation of the steady flow valve through the separate movement of the valve core. However, for the case of sudden increase or sudden decrease of water pressure, the reaction speed of the traditional steady flow valve is slow, and it cannot play a steady flow role in time. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the defect that the steady flow valve in the prior art relies on the separate movement of the valve core and has a slow reaction speed, and cannot play a steady flow role in time, and to provide a steady flow valve and a water heater comprising the same.

[0005] The present application solves the above technical problems by the following technical solutions:

[0007] The valve core assembly comprises a first moving member and a second moving member, the first moving member sequentially comprises a first shielding part and a first passage along the circumference of the flow passage, the first passage is through at both ends in the axial direction of the flow passage, the second moving member sequentially comprises a second shielding part and a second passage along the circumference of the flow passage, the second passage is through at both ends in the axial direction of the flow passage; one end of the first moving member in the axial direction of the flow passage towards the water outlet abuts against one end of the second moving member in the axial direction of the flow passage towards the water inlet, the first moving member and the second moving member are arranged to be able to rotate reversely around the axis of the flow passage when the valve core assembly moves along the axial direction of the flow passage;

[0008] The valve core assembly is capable of moving along the axial direction of the flow passage from a first position to a second position under the action of water pressure, the reset member is used for applying an action force to the valve core assembly towards the first position; when the valve core moves from the first position to the second position, the area of overlap of the first passage and the second passage in the axial direction of the flow passage decreases, the area of overlap of the first shielding part and the second passage in the axial direction of the flow passage increases, and the opening degree of the flow stabilizing valve decreases; when the valve core moves from the second position to the first position, the area of overlap of the first passage and the second passage in the axial direction of the flow passage increases, the area of overlap of the first shielding part and the second passage in the axial direction of the flow passage decreases, and the opening degree of the flow stabilizing valve increases.

[0009] In the scheme, the valve core assembly is capable of moving along the axial direction of the flow passage between a first position and a second position under the action of water pressure and the reset member, in the process, the first moving member and the second moving member in the valve core assembly are capable of rotating reversely around the axis of the flow passage, so as to change the relative positions among the first shielding part, the first passage, the second shielding part and the second passage, and then control the water flow size of the flow stabilizing valve by adjusting the overlapping area between the first passage and the second passage. And since the first moving member and the second moving member rotate reversely, the overlapping area of the first passage and the second passage can be quickly adjusted, that is, the opening degree of the flow stabilizing valve can be quickly adjusted, so as to improve the response speed of the flow stabilizing valve, so that the flow stabilizing valve can play a role in stabilizing flow in time.

[0010] Preferably, the flow stabilizing valve further comprises a first sliding channel and a second sliding channel, the first sliding channel and the second sliding channel are both arranged on the peripheral side wall of the valve body, and both the first sliding channel and the second sliding channel penetrate through the peripheral side wall of the valve body towards one side of the flow passage; a first end of the first sliding channel is arranged close to the water inlet, and a second end of the first sliding channel is inclined towards the direction of the water outlet; a first end of the second sliding channel is arranged close to the water outlet, and a second end of the second sliding channel is inclined towards the second end of the first sliding channel.

[0011] The first moving member comprises a first body and a first extension, the first body is arranged in the flow passage, one end of the first extension is connected with the first body, the other end of the first extension extends into the first sliding channel, and both ends of the first extension in the axial direction of the flow passage abut against the inner side wall of the first sliding channel; the second moving member comprises a second body and a second extension, the second body is arranged in the flow passage, one end of the second extension is connected with the second body, the other end of the second extension extends into the second sliding channel, and both ends of the second extension in the axial direction of the flow passage abut against the inner side wall of the second sliding channel.

[0012] In this design, the first slide rail converts the axial movement tendency of the first moving member in the flow channel into movement of the first moving member along the extension direction of the first slide rail, thereby achieving rotation of the first moving member around the axis of the flow channel. The second slide rail converts the axial movement tendency of the second moving member in the flow channel into movement of the second moving member along the extension direction of the second slide rail, thereby achieving rotation of the second moving member around the axis of the flow channel. Since the first and second slide rails have opposite inclination directions, opposite rotations of the first and second moving members can be achieved.

[0013] Preferably, the first slide and the second slide are independent of each other, and the first end and the second end of the first slide and the first end and the second end of the second slide are both closed ends;

[0015] In this design, the two ends of the first slide limit the rotation range of the first moving component, preventing it from rotating excessively. Similarly, the two ends of the second slide limit the rotation range of the second moving component, preventing it from rotating excessively. By limiting the rotation ranges of the first and second moving components, the alignment accuracy of the first and second channels is ensured, improving the reliability of the flow stabilization.

[0022] In the scheme, the above arrangement can realize the flow regulation of the steady flow valve in time when the first moving part and the second moving part generate reverse rotation, reduce the excessive rotation path of the first moving part and the second moving part, and further improve the response speed of the steady flow valve.

[0023] Preferably, the number of the first blocking parts is multiple, the number of the first channels is multiple, and the multiple first blocking parts and the multiple first channels are sequentially and spaced arranged along the circumferential direction of the flow passage.

[0024] And / or, the number of the second blocking parts is multiple, the number of the second channels is multiple, and the multiple second blocking parts and the multiple second channels are sequentially and spaced arranged along the circumferential direction of the flow passage.

[0025] In the scheme, the above arrangement can further improve the speed of the opening regulation of the steady flow valve and improve the response speed of the steady flow valve.

[0026] Preferably, the number of the first blocking parts, the first channels, the second blocking parts and the second channels is the same.

[0027] In the scheme, the above arrangement ensures that each first channel is blocked by a corresponding second blocking part, and each second channel is blocked by a corresponding first blocking part, thereby improving the reliability of the steady flow.

[0028] Preferably, the valve body has an end plate on the side away from the water inlet, the water outlet is arranged on the end plate, the reset member is a spring, one end of the spring abuts against the end plate, and the other end of the spring abuts against the second moving part.

[0070] The present application will be further described by way of example with reference to the accompanying drawings.

[0071] The present embodiment provides a water heater, a water system of the water heater is provided with a valve core assembly as claimed in claim 1. Figures 1-3The steady flow valve is used for ensuring the stability of water flow in the water channel system of the water heater and improving the water use experience of users.

[0072] As shown in the drawings, Figures 1-3 The steady flow valve comprises a valve body 1, a valve core assembly 2, a spring 3, a first sliding channel 4, a second sliding channel 5 and a spring mounting seat 6.

[0073] As shown in the drawings, Figures 1-4 The valve body 1 has a water inlet 11, a water outlet 12 and a flow passage 13. Specifically, Figure 1 The lower end of the valve body 1 is open to the water inlet 11, Figure 1 The upper end of the valve body 1 is open to the water outlet 12, and the flow passage 13 is arranged in the interior of the valve body 1 and used for connecting the water inlet 11 and the water outlet 12. Water flow can flow into the steady flow valve from the water inlet 11 and flow out of the steady flow valve from the water outlet 12 via the flow passage 13. Further, as shown in the drawings, Figure 1 The lower end of the valve body 1 is open, and the upper end of the valve body 1 further has an end plate 14. The water outlet 12 is arranged on the end plate 14, and the water outlet 12 penetrates the end plate 14 at both ends in the axial direction of the flow passage 13.

[0074] As shown in the drawings, Figure 3 And Figure 5 The valve core assembly 2 is arranged in the interior of the flow passage 13 and located on the side close to the water inlet 11 in the initial state (i.e. the state that the steady flow valve does not receive water pressure). The valve core assembly 2 can move in the axial direction of the flow passage 13 towards the water outlet 12 under the action of water pressure to move from a first position to a second position. In the embodiment, the first position refers to the position of the valve core assembly 2 in the initial state, i.e. the position when the valve core assembly 2 is farthest away from the water inlet 11; and the second position refers to the maximum steady flow position of the valve core assembly 2, i.e. the position when the valve core assembly 2 is closest to the water inlet 11. The maximum steady flow position refers to the position of the valve core assembly 2 when the opening degree of the steady flow valve is the smallest.

[0075] As shown in the drawings, Figure 5As shown, the valve core assembly 2 includes a first moving part 21 and a second moving part 22 in sequence along the axial direction of the flow passage 13, the first moving part 21 is close to the water inlet 11, the second moving part 22 is close to the water outlet 12, and the end of the first moving part 21 in the axial direction of the flow passage 13 towards the water outlet 12 abuts against the end of the second moving part 22 in the axial direction of the flow passage 13 towards the water inlet 11. After the water flows into the steady flow valve from the water inlet 11, the first moving part 21 is first pushed to move in the direction of the water outlet 12, and the first moving part 21 pushes the second moving part 22 to move in the direction of the water outlet 12. The abutment of the first moving part 21 and the second moving part 22 can ensure that the force is transmitted between the first moving part 21 and the second moving part 22, improve the response speed of the steady flow valve, and enable the steady flow valve to play a role in stabilizing the flow in time.

[0076] As shown in Figure 2 , the first moving part 21 includes a first shielding part 2111 and a first passage 2112 in sequence along the circumferential direction of the flow passage 13, and the two ends of the first passage 2112 in the axial direction of the flow passage 13 are penetrated. The second moving part 22 includes a second shielding part 2211 and a second passage 2212 in sequence along the circumferential direction of the flow passage 13, and the two ends of the second passage 2212 in the axial direction of the flow passage 13 are penetrated. The first moving part 21 and the second moving part 22 are arranged to be reversely rotatable around the axis of the flow passage 13 when the valve core assembly 2 moves along the axial direction of the flow passage 13, that is, the first moving part 21 and the second moving part 22 can rotate in opposite directions along the circumferential direction of the flow passage 13.

[0077] As shown in Figure 7 and Figure 8 , when the valve core moves from the first position to the second position, the area of the first passage 2112 and the second passage 2212 overlapping in the axial direction of the flow passage 13 decreases, the area of the first shielding part 2111 and the second passage 2212 overlapping in the axial direction of the flow passage 13 increases, and the opening degree of the steady flow valve decreases. As shown in Figure 1 and Figure 6 , when the valve core moves from the second position to the first position, the area of the first passage 2112 and the second passage 2212 overlapping in the axial direction of the flow passage 13 increases, the area of the first shielding part 2111 and the second passage 2212 overlapping in the axial direction of the flow passage 13 decreases, and the opening degree of the steady flow valve increases.

[0078] As shown in Figure 3As shown, the spring 3 is arranged inside the flow passage 13 between the end plate 14 of the valve body 1 and the second moving part 22, one end of the spring 3 abuts against the end plate 14, and the other end of the spring 3 abuts against the second moving part 22. When the valve core assembly 2 moves towards the second position under the action of water pressure, the spring 3 is compressed under force, and when the water flow stops, the spring 3 releases the elastic force and applies an action force to the valve core assembly 2 towards the first position to reset the valve core assembly 2, which is simple in structure and low in cost. In other alternative embodiments, the spring 3 can also be replaced by other reset parts capable of achieving the above-mentioned functions.

[0079] Specifically, as shown in the figures, Figure 3 The end plate 14 is provided with a first boss 15 on the side facing the flow passage 13, and the end of the spring 3 abutting against the end plate 14 is sleeved on the first boss 15. The spring mounting seat 6 is fixed to the end of the second moving part 22 away from the first moving part 21 in the axial direction of the flow passage 13, and the end of the spring 3 abutting against the second moving part 22 is sleeved on the spring mounting seat 6. Among them, the end of the second moving part 22 facing the spring 3 is provided with a second boss 2213, the outer circumferential side of the second boss 2213 is provided with a third extension 2214 extending to the outside of the second boss 2213, and the inner circumferential side of the spring mounting seat 6 is provided with a groove 61, and the third extension 2214 is accommodated in the groove 61, so as to realize the connection between the spring mounting seat 6 and the second moving part 22.

[0080] In other alternative embodiments, the third extension 2214 can be installed on the inner circumferential side of the spring mounting seat 6, and the groove 61 can be arranged on the outer circumferential side of the boss. Alternatively, the spring mounting seat 6 and the second moving part 22 can be connected by other connection methods.

[0081] The valve core assembly 2 can move between the first position and the second position in the axial direction of the flow passage 13 under the action of water pressure and the reset part, and in this process, the first moving part 21 and the second moving part 22 in the valve core assembly 2 can produce reverse rotation around the axis of the flow passage 13, so as to change the relative position between the first shielding part 2111, the first passage 2112, the second shielding part 2211 and the second passage 2212, and then adjust the overlapping area between the first passage 2112 and the second passage 2212 to control the water flow size of the steady flow valve. And since the first moving part 21 and the second moving part 22 are reversely rotated, the overlapping area of the first passage 2112 and the second passage 2212 can be quickly adjusted, that is, the opening of the steady flow valve can be quickly adjusted, so as to improve the response speed of the steady flow valve, so that the steady flow valve can play a role in stabilizing the flow in time.

[0082] As shown in the figures, Figures 1-5As shown, the first slide 4 and the second slide 5 are both arranged on the peripheral side wall of the valve body 1, the first slide 4 penetrates through both ends in the radial direction of the flow passage 13, the second slide 5 penetrates through both ends in the radial direction of the flow passage 13, the first slide 4 extends spirally upward, and the second slide 5 extends spirally downward. Specifically, as shown in Figure 1 As shown, the first end 41 of the first slide is arranged close to the water inlet 11, and the second end 42 of the first slide is inclined toward the direction of the water outlet 12; the first end 51 of the second slide is arranged close to the water outlet 12, and the second end 52 of the second slide is inclined toward the second end 42 of the first slide.

[0083] As shown in Figure 3 and Figure 5 The first moving part 21 includes a first body 211 and a first extension 212, the first body 211 is arranged in the flow passage 13, the first shielding part 2111 and the first passage 2112 are both arranged on the first body 211, one end of the first extension 212 is connected with the first body 211, the other end of the first extension 212 extends into the first slide 4, and both ends of the first extension 212 in the axial direction of the flow passage 13 abut against the inner side wall of the first slide 4. The first slide 4 is used to convert the movement trend of the first moving part 21 in the axial direction of the flow passage 13 into the movement of the first moving part 21 along the extension direction of the first slide 4, so as to realize the rotation of the first moving part 21 around the axis of the flow passage 13. The second moving part 22 includes a second body 221 and a second extension 222, the second body 221 is arranged in the flow passage 13, the second shielding part 2211 and the second passage 2212 are both arranged on the second body 221, one end of the second extension 222 is connected with the second body 221, the other end of the second extension 222 extends into the second slide 5, and both ends of the second extension 222 in the axial direction of the flow passage 13 abut against the inner side wall of the second slide 5. The second slide 5 is used to convert the movement trend of the second moving part 22 in the axial direction of the flow passage 13 into the movement of the second moving part 22 along the extension direction of the second slide 5, so as to realize the rotation of the second moving part 22 around the axis of the flow passage 13. Since the inclination directions of the first slide 4 and the second slide 5 are opposite, the reverse rotation of the first moving part 21 and the second moving part 22 can be realized.

[0084] In other alternative embodiments, the first slide 4 and / or the second slide 5 can only penetrate through one side of the peripheral side wall of the valve body 1 toward the flow passage 13, and the other side is closed. In the present embodiment, the first slide 4 and the second slide 5 are arranged to penetrate through both ends, which can reduce the matching precision of the first slide 4 and the first extension 212 and the matching precision of the second slide 5 and the second extension 222, reduce the machining precision and assembly difficulty of the first slide 4, the first extension 212, the second slide 5 and the second extension 222, and improve the production and assembly efficiency.

[0085] As shown in Figure 1 , the first slide 4 and the second slide 5 in the embodiment are independent of each other, and the first end 41 of the first slide, the second end 42 of the first slide, the first end 51 of the second slide and the second end 52 of the second slide are all closed ends. As shown in Figure 1 , when the valve core assembly 2 is in the first position, the first extension 212 abuts against the first end 41 of the first slide, and the second extension 222 abuts against the second end 52 of the second slide. As shown in Figure 7 , when the valve core assembly 2 is in the second position, the first extension 212 abuts against the second end 42 of the first slide, and the second extension 222 abuts against the first end 51 of the second slide.

[0086] The two ends of the first slide 4 limit the rotation range of the first moving part 21, preventing the first moving part 21 from rotating excessively. The two ends of the second slide 5 limit the rotation range of the second moving part 22, preventing the second moving part 22 from rotating excessively. By limiting the rotation range of the first moving part 21 and the second moving part 22, the alignment accuracy of the first passage 2112 and the second passage 2212 is ensured, and the reliability of the flow stabilization is improved.

[0087] As shown in Figure 4 and Figure 5 , the number of the first extensions 212 in the embodiment is two, and the two first extensions 212 are symmetrically arranged relative to the axis of the flow passage 13. The number of the first slides 4 is also two, and the two first slides 4 are arranged one-to-one with the two first extensions 212. The two first extensions 212 respectively extend into the corresponding first slide 4, improving the stability of the first moving part 21 during rotation. The number of the second extensions 222 is two, and the two second extensions 222 are symmetrically arranged relative to the axis of the flow passage 13. The number of the second slides 5 is also two, and the two second slides 5 are arranged one-to-one with the two second extensions 222. The two second extensions 222 respectively extend into the corresponding second slide 5, improving the stability of the second moving part 22 during rotation.

[0088] In other alternative embodiments, the number of the first extensions 212 in the first moving part 21 can be one or more, and the number of the first slides 4 is the same as the number of the first extensions 212. The number of the second extensions 222 in the second moving part 22 can also be one or more, and the number of the second slides 5 is the same as the number of the second extensions 222. The number of the first extensions 212 can be the same as or different from the number of the second extensions 222.

[0089] As shown in Figure 5As shown, the cross-sectional dimension of the first blocking part 2111 and the cross-sectional dimension of the second blocking part 2211 are the same, that is, the shape and size of the cross section of the first blocking part 2111 and the shape and size of the cross section of the second blocking part 2211 correspond to the same. The cross-sectional dimension of the first channel 2112 and the cross-sectional dimension of the second channel 2212 are the same, that is, the shape and size of the cross section of the first channel 2112 and the shape and size of the cross section of the second channel 2212 correspond to the same. When the valve core assembly 2 is located at the first position, the first blocking part 2111 and the second blocking part 2211 completely overlap in the axial direction of the flow passage 13, and the first channel 2112 and the second channel 2212 completely overlap in the axial direction of the flow passage 13, so that the first moving part 21 and the second moving part 22 can timely realize the flow regulation of the steady flow valve when generating reverse rotation, reduce the excessive rotation path of the first moving part 21 and the second moving part 22, and further improve the response speed of the steady flow valve.

[0090] As shown in Figure 5 , the number of first blocking parts 2111 is multiple, the number of first channels 2112 is multiple, and the multiple first blocking parts 2111 and the multiple first channels 2112 are sequentially and spaced apart along the circumferential direction of the flow passage 13. The number of second blocking parts 2211 is multiple, the number of second channels 2212 is multiple, and the multiple second blocking parts 2211 and the multiple second channels 2212 are sequentially and spaced apart along the circumferential direction of the flow passage 13. The present embodiment further improves the speed of opening degree adjustment of the steady flow valve and improves the response speed of the steady flow valve through the cooperation between the multiple first blocking parts 2111, the multiple first channels 2112, the multiple second blocking parts 2211 and the multiple second channels 2212. In other alternative embodiments, the number of first blocking parts 2111, first channels 2112, second blocking parts 2211 and second channels 2212 can also be one.

[0091] As shown in Figure 5 , the number of first blocking parts 2111, first channels 2112, second blocking parts 2211 and second channels 2212 is the same, which ensures that each first channel 2112 has a corresponding second blocking part 2211 for shielding, and each second channel 2212 has a corresponding first blocking part 2111 for shielding, thereby improving the reliability of the steady flow. In other alternative embodiments, the number of first blocking parts 2111, first channels 2112, second blocking parts 2211 and second channels 2212 can also be different.

[0092] Based on the specific structure of the steady flow valve described above, the working principle of the steady flow valve is briefly described as follows:

[0093] As shown in Figure 1 and Figure 6As shown, valve core assembly 2 is in its initial state, located in the first position. When the water pressure force on valve core assembly 2 exceeds the spring force, as... Figure 7 and Figure 8 As shown, the valve core assembly exhibits a tendency to move axially along the flow channel 13. The first moving member 21, constrained by the first slide rail 4, transforms its original axial movement along the flow channel 13 into a spiral upward movement along the extension direction of the first slide rail 4. That is, the first moving member 21 simultaneously moves in both the axial and circumferential directions within the flow channel 13, thereby changing the relative position of the first blocking portion 2111 and the first channel 2112. The second moving member 22, propelled by the first moving member 21, also moves simultaneously. Constrained by the second slide rail 5, the second moving member 22 transforms its original axial movement along the flow channel 13 into a spiral upward movement along the extension direction of the second slide rail 5. That is, the second moving member 22 simultaneously moves in both the axial and circumferential directions within the flow channel 13, thereby changing the relative position of the second blocking portion 2211 and the second channel 2212. Since the first moving part 21 and the second moving part 22 rotate in opposite directions, the overlapping area of ​​the first channel 2112 and the second channel 2212 decreases. That is, the area of ​​the first channel 2112 blocked by the second blocking part 2211 gradually increases, and the area of ​​the second channel 2212 blocked by the first blocking part 2111 gradually increases, thus reducing the opening of the flow stabilizing valve.

[0094] like Figure 7 and Figure 8 As shown, valve core assembly 2 is currently in the maximum flow-stabilizing position, and valve core assembly 2 is in the second position. When the water flow stops, spring 3 releases its elastic force, as shown... Figure 1 and Figure 6 As shown, the second moving member 22 moves spirally downward along the extension direction of the second slide rail 5, thereby changing the relative position of the second blocking part 2211 and the second channel 2212. The first moving member 21 moves simultaneously under the push of the second moving member 22, moving spirally downward along the extension direction of the first slide rail 4, thereby changing the relative position of the first blocking part 2111 and the first channel 2112. Since the first moving member 21 and the second moving member 22 still rotate in opposite directions, the overlapping area of ​​the first channel 2112 and the second channel 2212 increases, that is, the area of ​​the first channel 2112 blocked by the second blocking part 2211 gradually decreases, and the area of ​​the second channel 2212 blocked by the first blocking part 2111 gradually decreases, thus increasing the opening degree of the flow stabilizing valve.
