Description

Technical Field

[0001] The utility model relates to the technical field of valve parts, in particular to a water outlet valve. Background Art

[0002] The water circuit system of a wall-mounted boiler is a water heater powered by natural gas. It has a powerful central heating function for homes, can meet the heating needs of multiple rooms, and can provide domestic water for use in places such as family bathing and kitchens.

[0003] The water circuit system in the related art generally includes a combustion chamber, a heat exchange structure, an inlet valve, and a water outlet valve. The combustion chamber is usually installed on an indoor wall. The inlet valve can supply water to the combustion chamber. The heat exchange structure includes a heat exchange channel and a water supply channel that cooperate in heat exchange. The water outlet valve includes a valve body and a switching device. The valve body is provided with a hot water inlet, a heating water outlet interface, a bathroom water outlet interface, a heat exchange inlet interface, and a heat exchange outlet interface. The hot water inlet is connected to the outlet of the combustion chamber. The heat exchange inlet interface is connected to the inlet of the heat exchange channel. The heat exchange outlet interface is connected to the outlet of the water supply channel. The bathroom water outlet interface is connected to the heat exchange outlet interface. After the water in the water supply channel exchanges heat with the heat exchange channel, it can flow to the bathroom water outlet interface through the heat exchange outlet interface to provide bathroom hot water for users. The hot water inlet is switched through the switching device to selectively communicate with the heating water outlet interface or the heat exchange inlet interface.

[0004] In addition, a bypass valve part is also provided on the valve body. A bypass flow channel is formed inside the bypass valve part. The bypass flow channel can supply water to the heat exchange structure to prevent the heat exchange structure from being damaged due to dry burning caused by water shortage. However, in the prior art, the bypass valve part is often installed behind the valve body. When it is necessary to repair the bypass flow channel inside the bypass valve part, the entire water outlet valve needs to be removed from the heat exchange structure, which is extremely inconvenient.

[0005] Therefore, there is an urgent need to propose a water outlet valve to solve the above problems. Summary of the Utility Model

[0053] Embodiment 1

[0054] Figure 1 The waterway structure diagram of the wall-mounted boiler waterway system provided by this embodiment is shown. Figure 2 The structural diagram of the water outlet valve 100 provided by this embodiment is shown from one perspective. Figure 3The structural schematic diagram of the water outlet valve 100 provided in this embodiment is shown from another perspective. As Figures 1-3 shown, this embodiment provides a water circuit system for a wall-mounted boiler. The water circuit system for the wall-mounted boiler includes a combustion chamber 200, a heat exchange structure 300, a water inlet valve 400, and a water outlet valve 100. The combustion chamber 200 can heat the water therein; the heat exchange structure 300 includes a heat exchange channel 310 and a water supply channel 320 that are thermally mated; the water inlet valve 400 can supply water to the combustion chamber 200 and the water supply channel 320; the water outlet valve 100 includes a valve body 1. The valve body 1 is provided with a hot water inlet 1111, a first heat exchange water inlet flow channel 131, a first heat exchange water outlet flow channel 141, a heating channel 121, and a bathroom channel 142; the hot water inlet 1111 is connected to the hot water outlet 201 of the combustion chamber 200 through a connecting pipeline 600, and the hot water inlet 1111 can be selectively connected to the heating channel 121 or the first heat exchange water inlet flow channel 131; the first heat exchange water inlet flow channel 131 is connected to the inlet of the heat exchange channel 310, the outlet of the heat exchange channel 310 is connected to the second heat exchange water outlet flow channel 402 of the water inlet valve 400, the inlet of the water supply channel 320 is connected to the second heat exchange water inlet flow channel 401 of the water inlet valve 400, and the outlet of the water supply channel 320 is connected to the first heat exchange water outlet flow channel 141.

[0055] During use, when the hot water inlet 1111 is connected to the heating channel 121, the hot water heated by the combustion chamber 200 can flow through the hot water outlet 201, the connecting pipeline 600, the hot water inlet 1111, and the heating channel 121 in sequence, and then flow into the heating system 500 to provide heating requirements for users. The water that has exchanged heat with the outside in the heating system 500 can then flow through the water inlet valve 400 into the combustion chamber 200 to be heated again, thereby forming a heating water circulation loop; when the hot water inlet 1111 is connected to the first heat exchange water inlet flow channel 131, the hot water heated by the combustion chamber 200 can flow through the hot water outlet 201, the connecting pipeline 600, the hot water inlet 1111, and the first heat exchange water inlet flow channel 131 in sequence and then flow into the heat exchange channel 310 of the heat exchange structure 300. After exchanging heat with the water in the water supply channel 320, it flows through the water inlet valve 400 into the combustion chamber 200 to be heated again, thereby forming a heat exchange circulation loop; the water in the external water source can flow into the water supply channel 320 of the heat exchange structure 300 through the water inlet valve 400. After exchanging heat with the water in the heat exchange channel 310, it then flows through the first heat exchange water outlet flow channel 141 and the bathroom channel 142 in sequence and flows into the bathroom system to provide domestic water for users.

[0056] It should be noted that the heating system 500 specifically refers to terminal heat dissipation components such as radiators, floor heating pipes, or fan coil units. The water heated in the combustion chamber 200 can be pumped to the above-mentioned terminal heat dissipation components through the water outlet valve 100, and the heat is dissipated into the indoor air by heat dissipation, thereby increasing the indoor environmental temperature to meet the heating needs of users. The bathroom system specifically refers to water-using devices for users to take showers, wash their faces, etc. Therefore, both the heating system 500 and the bathroom system are relatively mature technologies in this field, and the specific structures of the heating system 500 and the bathroom system will not be elaborated in this embodiment.

[0057] In this embodiment, the material of the connecting pipeline 600 is not limited, and it can be made of copper pipes, corrugated pipes, stainless steel pipes, plastic pipes, etc.

[0058] It should also be noted that both the combustion chamber 200 and the water inlet valve 400 are relatively mature technologies in this field, and the specific structures of the combustion chamber 200 and the water inlet valve 400 will not be elaborated in this embodiment.

[0059] Optionally, the valve body 1 further includes a bypass valve portion 15. The bypass valve portion 15 is used to supply water to the heat exchange structure 300 when the hot water inlet 1111 is connected to the heating channel 121, so as to prevent the heat exchange structure 300 from being damaged due to dry burning caused by water shortage. However, in the prior art, the bypass valve portion is often installed behind the valve body. When it is necessary to repair the bypass flow channel in the bypass valve portion, the entire water outlet valve needs to be removed from the heat exchange structure, which is extremely inconvenient. To solve this problem, this embodiment also provides a water outlet valve 100, which can facilitate the operator to repair the bypass valve portion 15.

[0060] Figure 4 Fig. shows a schematic structural diagram of the water outlet valve 100 provided in this embodiment from another perspective. Figure 5 Fig. shows Figure 4 a sectional structural diagram at A-A. As Figures 4-5 and in combination with Figure 2As shown in the figure, the water outlet valve 100 provided in this embodiment includes a valve body 1. The valve body 1 includes a valve main body 10 and a first valve part 13. A heating channel 121, a main valve cavity 1101, and a first cavity 1102 and a second cavity 1103 located on both sides of the main valve cavity 1101 are formed in the valve main body 10. The first cavity 1102 is communicated with the heating channel 121, and the main valve cavity 1101 can selectively communicate with the first cavity 1102 or the second cavity 1103. The first valve part 13 is connected to one side of the valve main body 10, and a first heat exchange water inlet flow channel 131 communicated with the second cavity 1103 is arranged in the first valve part 13. The first heat exchange water inlet flow channel 131 is used to connect the heat exchange structure 300. The bypass valve part 15 is connected to the front side of the valve main body 10, and a bypass flow channel 151 is opened in the bypass valve part 15. The bypass flow channel 151 can selectively communicate the heating channel 121 and the second cavity 1103. By arranging the bypass valve part 15, when the main valve cavity 1101 is communicated with the first cavity 1102, when the heat exchange structure 300 dries out due to lack of water, the water in the heating channel 121 can flow through the bypass flow channel 151 and then through the second cavity 1103 and the first heat exchange water inlet flow channel 131 into the heat exchange channel 310 of the heat exchange structure 300, so as to avoid damage to the heat exchange structure 300 caused by dry burning due to lack of water, thereby ensuring the use safety of the heat exchange structure 300. By arranging the bypass valve part 15 on the front side of the valve main body 10, the operator can perform maintenance and repair on it from the front of the valve main body 10 without removing the entire water outlet valve 100, improving the convenience of the operator's operation.

[0061] For the convenience of description, as Figure 2 shown in the figure, the height direction of the water outlet valve 100 after actual installation is defined as the up and down direction. Among them, the side of the water outlet valve 100 close to the combustion chamber 200 is defined as up, the side of the water outlet valve 100 away from the combustion chamber 200 is defined as down, the side of the water outlet valve 100 close to the heat exchange structure 300 is defined as back, and the side of the water outlet valve 100 away from the heat exchange structure 300 is defined as front. When the user stands facing the front of the water outlet valve 100, the side of the water outlet valve 100 facing the user's right hand is defined as right, and the side of the water outlet valve 100 facing the user's left hand is defined as left. In addition, the height direction of the valve body 1 refers to the up and down direction, the width direction of the valve body 1 refers to the left and right direction, and the thickness direction of the valve body 1 refers to the front and back direction. That is to say, in this embodiment, since the bypass valve part 15 is connected to the front side of the valve main body 10, when the operator faces the water circuit system of the wall-mounted boiler, the operator is directly opposite to the bypass valve part 15, and can conveniently repair the bypass flow channel 151 in the bypass valve part 15, which is convenient and fast.

[0062] Optionally, a check valve 1511 is provided in the bypass flow channel 151 to only allow the water flow in the heating channel 121 to flow into the second chamber 1103, preventing the water in the second chamber 1103 from flowing back. Herein, the check valve 1511 is a commonly used valve structure in the art, and the specific structure and working principle of the check valve 1511 will not be elaborated in this embodiment.

[0063] Optionally, a bypass port 152 communicating with the bypass flow channel 151 is provided on the bypass valve portion 15. The bypass port 152 is detachably blocked by a bypass plug 153. One end of the check valve 1511 abuts against the inner side of the bypass plug 153. During maintenance, the operator only needs to open the bypass plug 153, which is convenient and easy.

[0064] As Figure 3 and Figure 5 As shown, the valve body 10 includes a three-way valve portion 11 and an extended valve portion 12. The first chamber 1102, the main valve chamber 1101, and the second chamber 1103 are arranged in sequence along the first direction and are all formed within the three-way valve portion 11; the extended valve portion 12 is connected to the three-way valve portion 11. The heating channel 121 is provided in the extended valve portion 12 and extends along the second direction. The bypass valve portion 15 is connected to the extended valve portion 12; wherein, the first direction and the second direction are arranged at an angle. Compared with the prior art solution in which the three-way valve portion 11 and the extended valve portion 12 are coaxially arranged, by setting the valve body 10 as the three-way valve portion 11 and the extended valve portion 12 connected at an angle, the size of the valve body 1 in the first direction can be greatly reduced, and the size of the valve body 1 in the second direction can be fully utilized, thereby achieving the effect of reducing the height of the valve body 1, and further reducing the installation height of the entire water circuit system of the wall-mounted boiler to meet the miniaturization requirements of the water circuit system of the wall-mounted boiler.

[0065] In this embodiment, the first direction specifically refers to the front-back direction, and the second direction specifically refers to the up-down direction. That is to say, the three-way valve portion 11 extends along the front-back direction, the extended valve portion 12 extends along the up-down direction, and the three-way valve portion 11 and the extended valve portion 12 are perpendicularly arranged. Of course, in other embodiments, the three-way valve portion 11 and the extended valve portion 12 can also be arranged at other angles, and the above effects can also be achieved.

[0066] It should be noted that, in this embodiment, the axial direction of the bypass valve portion 15 is parallel to the axial direction of the three-way valve portion 11, that is, the bypass valve portion 15 also extends along the front-back direction. This design can make the bypass valve portion 15 located between the three-way valve portion 11 and the extended valve portion 12, making the structure of the entire outlet valve 100 more compact, the bypass connection distance shorter, and further capable of shortening the response time.

[0067] Of course, in other embodiments, the axial direction of the bypass valve portion 15 can also be set at an angle to the axial direction of the three-way valve portion 11. In this example, for the convenience of the operator to repair the bypass valve portion 15, the extending direction of the bypass valve portion 15 can be set to gradually incline downward along the direction away from the extending valve portion 12, so as to prevent the bypass plug 153 from interfering with other structures and affecting the operation of the operator.

[0068] As Figure 2 and Figure 3 shown, the valve body 1 further includes a second valve portion 14. The second valve portion 14 is connected to the valve main body 10, and the first valve portion 13 and the second valve portion 14 are arranged at intervals in the up-down direction. The first heat exchange water outlet flow channel 141 and the sanitary channel 142 are both provided in the second valve portion 14. It should be noted that, in this embodiment, the three-way valve portion 11 is arranged in the front-rear direction, the extending valve portion 12 is connected to the lower part of the three-way valve portion 11, and the first valve portion 13 and the second valve portion 14 are respectively connected to the right side of the three-way valve portion 11 and the right side of the extending valve portion 12, so that the entire valve body 1 is generally arranged in a square layout, making full use of the space of the valve body 1 in the width direction and the thickness direction, greatly reducing the installation height of the entire water circuit system of the wall-mounted boiler, and optimizing the space layout of the entire system.

[0069] Figure 6 Fig. shows the structural schematic diagram of the switching mechanism 3 and the separating component 112 provided in this embodiment. Figure 7 Fig. shows the sectional structural schematic diagram of the switching mechanism 3 and the separating component 112 provided in this embodiment. As Figures 6-7 and in combination with Figure 5 shown, the water outlet valve 100 further includes a switching mechanism 3. The switching mechanism 3 is movably arranged in the three-way valve portion 11 to selectively open the passage between the main valve cavity 1101 and the first cavity 1102 or the passage between the main valve cavity 1101 and the second cavity 1103. When the switching mechanism 3 opens the passage between the main valve cavity 1101 and the first cavity 1102, the hot water in the combustion chamber 200 can circulate in the heating water circulation loop; when the switching mechanism 3 opens the passage between the main valve cavity 1101 and the second cavity 1103, the hot water in the combustion chamber 200 can circulate in the heat exchange circulation loop, that is, the switching mechanism 3 realizes the switching between the heating water circulation loop and the heat exchange circulation loop to selectively provide domestic water for users or meet the heating needs of users.

[0070] Specifically, the three-way valve section 11 includes a body 111 and a separating assembly 112 disposed in the valve cavity of the body 111. The separating assembly 112 includes a first separating sleeve 1121 and a second separating sleeve 1122. The first separating sleeve 1121 and the second separating sleeve 1122 are spaced apart along the axial direction of the valve cavity of the body 111 and are both sealingly fitted with the cavity wall of the valve cavity of the body 111, thereby separating the valve cavity of the body 111 to form a main valve cavity 1101, a first cavity 1102, and a second cavity 1103. The first separating sleeve 1121 is located between the main valve cavity 1101 and the first cavity 1102, and the second separating sleeve 1122 is located between the main valve cavity 1101 and the second cavity 1103. The switching mechanism 3 includes a valve stem 31, a first sealing seat 32, and a second sealing seat 33. The first sealing seat 32 and the second sealing seat 33 are arranged at intervals along the axial direction of the valve stem 31 and are both connected to the valve stem 31. The valve stem 31 can move along the axial direction of the three-way valve section 11, thereby driving the first sealing seat 32 and the second sealing seat 33 to move, so as to selectively block the first separating sleeve 1121 with the first sealing seat 32 or block the second separating sleeve 1122 with the second sealing seat 33. When the first sealing seat 32 blocks the first separating sleeve 1121, the second sealing seat 33 is spaced apart from the second separating sleeve 1122. At this time, the main valve cavity 1101 is communicated with the second cavity 1103. When the second sealing seat 33 blocks the second separating sleeve 1122 and the first sealing seat 32 is spaced apart from the first separating sleeve 1121, the main valve cavity 1101 is communicated with the first cavity 1102, thereby realizing three-way switching.

[0071] Optionally, the water outlet valve 100 further includes a driving mechanism 2 (refer to Figure 10 ), and the output end of the driving mechanism 2 is connected to the valve stem 31 to drive the valve stem 31 to move along the axial direction of the three-way valve section 11. In this embodiment, the driving mechanism 2 is a synchronous motor. Of course, in other embodiments, according to different designs of the switching mechanism 3, the driving mechanism 2 can also be a stepping motor or other driving devices.

[0072] It is worth noting that by arranging the three-way valve section 11 in the front-rear direction, the driving mechanism 2 can also be installed on the front side of the valve body 1 (the driving mechanism in the prior art is usually installed between the valve body and the combustion chamber), so as to avoid the spaced area between the valve body 1 and the combustion chamber 200, make full use of the space of the valve body 1 in the thickness direction, further shorten the distance between the valve body 1 and the combustion chamber 200, and reduce the height of the entire water circuit system of the wall-mounted boiler.

[0073] Such as Figure 3 and Figure 5As shown, the first chamber 1102 is connected to the heating channel 121 through the heating communication flow channel 1001, and the axis of the heating communication flow channel 1001 is inclined relative to the axis of the three-way valve portion 11. In the prior art, the first chamber 1102 and the heating channel 121 are coaxially arranged and extend in the up-down direction. When the switching mechanism 3 opens the passage between the main valve chamber 1101 and the first chamber 1102, the first sealing seat 32 is equivalent to blocking the passage between the first chamber 1102 and the heating channel 121, and the water in the main valve chamber 1101 will flow between the periphery of the first sealing seat 32 and the chamber wall of the first chamber 1102, thus generating a relatively large water resistance. In this embodiment, by providing the inclined heating communication flow channel 1001, an opening can be exactly formed at the interval in the direction along the axis of the three-way valve portion 11 downward between the first sealing seat 32 and the first partition sleeve 1121, and the water in the main valve chamber 1101 can flow out from this opening under the action of its own gravity, thereby reducing the water resistance, increasing the water flow rate to a certain extent, and also playing a role in reducing the head damage of the circulating water pump, prolonging the service life of the circulating water pump, and reducing the user's usage cost.

[0074] Figure 8 Fig. 4 shows a schematic structural view of the water outlet valve 100 provided in this embodiment from another perspective. Figure 9 shows Figure 8 the sectional structural view at B-B. As Figures 8-9 and in combination with Figure 4 As shown, the second chamber 1103 is connected to the first heat exchange water inlet flow channel 131 through the heat exchange communication flow channel 1002, and the axis of the heat exchange communication flow channel 1002 is inclined relative to the valve body 10. Compared with the straight channel in the prior art, by providing the inclined heat exchange communication flow channel 1002 in this embodiment, the cross-sectional area of the inlet of the heat exchange communication flow channel 1002 is equivalently increased, thereby reducing the water resistance of the water flowing from the second chamber 1103 to the first heat exchange water inlet flow channel 131.

[0075] It should be noted that the heating communication flow channel 1001 and the heat exchange communication flow channel 1002 that are inclined relative to the axis of the three-way valve portion 11 achieve the direct connection between the corresponding flow channels. This design is convenient for processing, can reduce the use of sealing plugs, and can also reduce the potential risk points of leakage.

[0076] Optionally, a connection interface 132 connected to the first heat exchange water inlet flow channel 131 is further provided on the first valve portion 13, and a sensing component 4 can be connected at the connection interface 132 to detect parameters such as the temperature and pressure of the water in the first heat exchange water inlet flow channel 131. Optionally, the sensing component 4 can be but is not limited to a pressure switch, a pressure sensor, a pressure gauge, a temperature sensor, etc.

[0077] Continuing as Figure 2As shown, the hot water inlet 1111 is opened on the three-way valve portion 11 and is connected to the main valve chamber 1101 to receive the hot water flowing out of the hot water outlet 201 of the combustion chamber 200 .

[0078] In this embodiment, the hot water inlet 1111 is arranged on the side of the three-way valve portion 11 away from the first valve portion 13, that is, the hot water inlet 1111 is opened on the left side of the three-way valve portion 11. With this arrangement, the height dimension of the entire water outlet valve 100 can be reduced, and when assembling the wall-mounted boiler water system, since the drive mechanism 2 is installed on the front side of the valve body 1, only a space needs to be reserved between the combustion chamber 200 and the top of the valve body 1 for connecting the connecting pipe 600 and the hot water outlet 201 of the combustion chamber 200.

[0079] Embodiment 2

[0080] This embodiment provides a water outlet valve 100 , the specific structure of which is substantially the same as the specific structure of the water outlet valve 100 in the first embodiment, except that the location of the hot water inlet 1111 is different.

[0081] Figure 10 A schematic structural diagram of a water outlet valve 100 provided in this embodiment is shown. Figure 11 A schematic structural diagram of the water system of a wall-mounted boiler provided in this embodiment is shown. Figure 12 The schematic diagram of the structure of the water system of the wall-mounted boiler provided by the prior art is shown. Figures 10-11 Combined with Figure 1 , Figure 5 As shown, the hot water inlet 1111 is opened at the top of the three-way valve part 11 and is arranged toward the hot water outlet 201 of the combustion chamber 200, and the hot water inlet 1111 is directly connected with the hot water outlet 201 through the connecting pipe 600. Figure 12 For the solution of setting the hot water inlet 1111 on the side of the valve body 1, with the above-mentioned setting method, the connecting pipe 600 can be directly pulled down to the hot water inlet 1111 after being connected to the hot water outlet 201, thereby shortening the distance between the hot water inlet 1111 and the hot water outlet 201, so as to reduce the length and material of the connecting pipe 600, thereby reducing the material cost to a certain extent; in addition, the above-mentioned setting also allows the connecting pipe 600 to be processed into a straight pipe structure, and the hot water inlet 1111 and the hot water outlet 201 can be connected without too many bends, thereby avoiding the phenomenon of large water resistance caused by too many bends on the connecting pipe 600.

[0082] In this embodiment, the hot water inlet 1111 is coaxially arranged with the heating channel 121, and the first chamber 1102 and the second chamber 1103 are respectively located on both sides of the axis of the hot water inlet 1111, so as to facilitate the machining of the valve body 1. Of course, in other embodiments, the axis of the hot water inlet 1111 and the axis of the heating channel 121 can also be set to be parallel but not coaxial, and the above effects can also be achieved.

[0083] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
