Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a water outlet valve and a water circuit system of a wall-mounted boiler. Background Art

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

[0003] The water circuit system of a wall-mounted boiler in the related art generally includes a combustion chamber, a heat exchange structure, a water inlet valve and a water outlet valve. The combustion chamber is usually installed on the indoor wall. The water 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 with each other for heat exchange; the water outlet valve includes a valve body and a switching device. The valve body has a three-way valve cavity, a hot water inlet, a heating channel, a bathroom channel, a heat exchange inlet and a heat exchange outlet. The hot water inlet is connected to the outlet of the combustion chamber and communicates with the three-way valve cavity. The three-way valve cavity is switched by the switching device to selectively communicate with the heating channel or the heat exchange inlet; the heat exchange inlet is connected to the inlet of the heat exchange channel of the heat exchange structure, and the heat exchange outlet is connected to the outlet of the water supply channel of the heat exchange structure. The bathroom channel is connected to the heat exchange outlet. After the water in the water supply channel exchanges heat with the heat exchange channel, it can flow to the bathroom channel through the heat exchange outlet to provide bathroom hot water for users; when the three-way valve cavity communicates with the heating channel, the hot water in the combustion chamber can flow to the heating channel through the hot water inlet and the three-way valve cavity in sequence to meet the heating needs of users. However, in the prior art, the three-way valve cavity is coaxially arranged with the heating channel, and the axial direction of the three-way valve cavity extends in the up-down direction during installation, resulting in a relatively large size of the entire water outlet valve in the height direction, and further causing a relatively high installation height of the entire water circuit system of the wall-mounted boiler, which cannot meet the market demand for miniaturization of the water circuit system of the wall-mounted boiler.

[0004] Therefore, it is urgent to propose a water outlet valve to solve the above problems. Summary of the Utility Model

[0056] Embodiment 1

[0057] Figure 1 Shows a schematic diagram of the water path structure of the wall-mounted boiler water path system provided in this embodiment. Figure 2 Shows a schematic diagram of the water outlet valve 100 provided in this embodiment from one perspective. Figure 3 Shows a schematic diagram of the water outlet valve 100 provided in this embodiment from another perspective. As Figures 1-3 shown, this embodiment provides a wall-mounted boiler water path system, which 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 in thermal cooperation; 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, and 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.

[0058] In use, when the hot water inlet 1111 is in communication with 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 into the combustion chamber 200 through the water inlet valve 400 to be reheated, thus forming a heating water circulation loop; when the hot water inlet 1111 is in communication with 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 into the combustion chamber 200 through the water inlet valve 400 to be reheated, thus forming a heat exchange water 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.

[0059] It should be explained 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 through heat dissipation, thereby increasing the indoor environmental temperature to meet the heating requirements 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.

[0060] This embodiment does not limit the material of the connecting pipeline 600, and it can be made of copper pipes, corrugated pipes, stainless steel pipes, plastic pipes, etc.

[0061] 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.

[0062] In the existing wall-mounted boiler water circuit system, there is often a situation where the overall installation height is relatively high, which cannot meet the market demand for the miniaturization of the wall-mounted boiler water circuit system. To solve this problem, this embodiment also provides a water outlet valve 100, which can make full use of the space in the thickness direction of the valve body 1 to reduce the height of the water outlet valve 100, and further reduce the installation height of the entire wall-mounted boiler water circuit system, thereby meeting the market demand for the miniaturization of the wall-mounted boiler water circuit system.

[0063] Figure 4Shows a schematic structural diagram of the water outlet valve 100 provided in this embodiment from another perspective. Figure 5 Shows Figure 4 A schematic cross-sectional structure diagram at A-A. As Figures 4-5 And in combination with Figure 1 , Figure 2 As shown, 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 portion 13. The valve main body 10 includes a three-way valve portion 11 and an extended valve portion 12 connected to the three-way valve portion 11. A first chamber 1102, a main valve chamber 1101, and a second chamber 1103 are formed in the three-way valve portion 11 in sequence along a first direction. And the main valve chamber 1101 can selectively communicate with the first chamber 1102 or the second chamber 1103. A heating channel 121 extending along a second direction is provided in the extended valve portion 12, and the heating channel 121 communicates with the first chamber 1102; the first valve portion 13 is connected to the valve main body 10, and a first heat exchange water inlet flow channel 131 communicating with the second chamber 1103 is provided in the first valve portion 13; 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 main 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, so as to achieve the effect of reducing the height of the valve body 1, and further reduce 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.

[0064] For the convenience of description, as Figure 2 shown, 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.

[0065] In this embodiment, the first direction specifically refers to the front and back direction, and the second direction specifically refers to the up and down direction. That is to say, the three-way valve portion 11 extends along the front and back direction, the extended valve portion 12 extends along the up and 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] AsFigure 2 and Figure 5 As 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-and-down direction. The first heat exchange water outlet flow channel 141 and the sanitary channel 142 are both opened 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-back direction, the extension 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 left side of the three-way valve portion 11 and the right side of the extension valve portion 12, so that the entire valve body 1 is generally square in 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.

[0067] Figure 6 Fig. shows a schematic structural view of the switching mechanism 3 and the separation assembly 112 provided in this embodiment. Figure 7 Fig. shows a sectional structural view of the switching mechanism 3 and the separation assembly 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.

[0068] Specifically, the three-way valve portion 11 includes a body 111 and a partition assembly 112 disposed in the valve cavity of the body 111. The partition assembly 112 includes a first partition sleeve 1121 and a second partition sleeve 1122. The first partition sleeve 1121 and the second partition 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 dividing the valve cavity of the body 111 into a main valve cavity 1101, a first cavity 1102, and a second cavity 1103. The first partition sleeve 1121 is located between the main valve cavity 1101 and the first cavity 1102, and the second partition 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 portion 11, thereby driving the first sealing seat 32 and the second sealing seat 33 to move, so as to selectively block the first partition sleeve 1121 with the first sealing seat 32 or block the second partition sleeve 1122 with the second sealing seat 33. When the first sealing seat 32 blocks the first partition sleeve 1121, the second sealing seat 33 is spaced apart from the second partition 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 partition sleeve 1122 and the first sealing seat 32 is spaced apart from the first partition sleeve 1121, the main valve cavity 1101 is communicated with the first cavity 1102, thereby realizing three-way switching.

[0069] Optionally, the water outlet valve 100 further includes a driving mechanism 2. 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 portion 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.

[0070] It should be noted that by arranging the three-way valve portion 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 interval 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.

[0071] Such as Figure 2 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. 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 large water resistance. In this embodiment, by setting the inclined heating communication flow channel 1001, an opening can just be formed at the interval in the downward direction along the axis of the three-way valve portion 11 between the first sealing seat 32 and the first partition sleeve 1121. 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, also playing a role in reducing the head loss of the circulating water pump, prolonging the service life of the circulating water pump, and reducing the user's usage cost.

[0072] Optionally, the inclination angle of the heating communication flow channel 1001 relative to the axis of the three-way valve portion 11 is 25° to 75°. This angle range can facilitate the machining of the valve body 1 and can avoid the valve body 1 having too large dimensions in the up-down direction or the front-back direction, resulting in a large installation space for the water outlet valve 100 and increasing the installation difficulty. Exemplarily, the inclination angle of the heating communication flow channel 1001 relative to the axis of the three-way valve portion 11 can be 30°, 40°, 45°, 50°, 60°, etc.

[0073] Figure 8 The sectional view schematic diagram of the water outlet valve 100 provided by this embodiment is shown from another perspective. As Figure 8 and in combination with Figure 4 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 setting the inclined heat exchange communication flow channel 1002 in this embodiment, it is equivalent to increasing the cross-sectional area of the inlet of the heat exchange communication flow channel 1002, thereby reducing the water resistance of the water flowing from the second chamber 1103 to the first heat exchange water inlet flow channel 131.

[0074] Optionally, the inclination angle of the heat exchange communication flow channel 1002 relative to the axis of the three-way valve portion 11 is 25° to 75°. This angle range can facilitate the machining of the valve body 1 and can avoid the valve body 1 having too large dimensions in the left-right direction or the front-back direction, resulting in a large installation space for the water outlet valve 100 and increasing the installation difficulty. Exemplarily, the inclination angle of the heat exchange communication flow channel 1002 relative to the axis of the three-way valve portion 11 can be 30°, 40°, 45°, 50°, 60°, etc.

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

[0076] Optionally, a connection interface 132 communicating with the first heat exchange water inlet flow path 131 is further provided on the first valve portion 13. 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 path 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] Continue as Figures 2-5 shown, a bypass flow path 151 is further provided on the valve body 1. The bypass flow path 151 can selectively communicate the heating channel 121 and the second chamber 1103. When the main valve chamber 1101 is in communication with the first chamber 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 path 151 and sequentially through the second chamber 1103, the heat exchange connection flow path 1002, and the first heat exchange water inlet flow path 131 into the heat exchange channel 310 to prevent the heat exchange structure 300 from being damaged due to dry burning caused by lack of water.

[0078] Specifically, the valve body 1 further includes a bypass valve portion 15. The bypass valve portion 15 is formed on the extended valve portion 12. The bypass flow path 151 is opened in the bypass valve portion 15, and a check valve 1511 is provided in the bypass flow path 151 to only allow the water in the heating channel 121 to flow into the second chamber 1103 and prevent the water in the second chamber 1103 from flowing back. Among them, the check valve 1511 is a relatively common valve structure in the art, and the specific structure and working principle of the check valve 1511 will not be elaborated in this embodiment.

[0079] Optionally, a bypass port 152 communicating with the bypass flow path 151 is opened on the bypass valve portion 15. A bypass plug 153 is detachably plugged at the bypass port 152. One end of the check valve 1511 abuts against the inner side of the bypass plug 153. When maintenance is required, the operator only needs to open the bypass plug 153, which is convenient and fast.

[0080] As Figure 2As shown, in this embodiment, the bypass valve portion 15 is formed on the front side of the extended valve portion 12, that is, the bypass valve portion 15 is located below the driving mechanism 2. The operator can perform maintenance on it from the front of the valve body 1 without removing the entire water outlet valve 100, further improving the convenience of the operator's operation. And this design makes 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 water outlet valve 100 more compact and the bypass connection distance shorter, thereby being able to shorten the response time.

[0081] 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 in the front-back direction.

[0082] Of course, in other embodiments, the axial direction of the bypass valve portion 15 can also be set to form an angle with the axial direction of the three-way valve portion 11. In this example, for the convenience of the operator to maintain 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 extended valve portion 12 to avoid the bypass plug 153 being blocked by the driving mechanism 2, affecting the operator's operation.

[0083] Figure 9 The structural schematic diagram of the water circuit system of the wall-mounted boiler provided in this embodiment is shown. Figure 10 The structural schematic diagram of the water circuit system of the wall-mounted boiler provided by the prior art is shown. As Figure 9 And in combination with Figure 2 、 Figure 5 As shown, the hot water inlet 1111 is opened on the three-way valve portion 11 and is connected to the main valve cavity 1101 to receive the hot water flowing out from the hot water outlet 201 of the combustion chamber 200. In this embodiment, the hot water inlet 1111 on the three-way valve portion 11 is arranged facing the hot water outlet 201 of the combustion chamber 200, and the hot water inlet 1111 and the hot water outlet 201 are directly connected through the connecting pipeline 600. Compared with Figure 10 the solution of arranging the hot water inlet 1111 on the side of the valve body 1 shown, by adopting the above setting method, the connecting pipeline 600 can be directly pulled down to the hot water inlet 1111 after being connected from the hot water outlet 201, thereby shortening the distance between the hot water inlet 1111 and the hot water outlet 201, reducing the length and material usage of the connecting pipeline 600, and thus being able to reduce the material cost to a certain extent; in addition, the above setting also enables the connecting pipeline 600 to be processed into a straight pipe structure, and the connection between the hot water inlet 1111 and the hot water outlet 201 can be realized without too many bending parts, thereby avoiding the phenomenon of large water resistance caused by too many bending parts on the connecting pipeline 600.

[0084] In this embodiment, the hot water inlet 1111 is coaxially arranged with the heating channel 121, and the first cavity 1102 and the second cavity 1103 are respectively located on both sides of the axis of the hot water inlet 1111, so as to facilitate the processing 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 arranged to be parallel but not coaxial, and the above-mentioned effect can also be achieved.

[0085] Embodiment 2

[0086] This embodiment provides a water outlet valve 100 , the specific structure of which is substantially the same as that of the water outlet valve 100 in the first embodiment, except that the bypass valve portion 15 is disposed in a different direction.

[0087] Figure 11 A schematic structural diagram of the water outlet valve 100 provided in this embodiment at a viewing angle is shown. Figure 12 A schematic structural diagram of the water outlet valve provided in this embodiment from another perspective is shown. Figure 13 Shows Figure 12 Schematic diagram of the cross-sectional structure at BB. Figures 11-13 As shown, in this embodiment, the bypass valve part 15 is connected to the side of the three-way valve part 11 away from the first valve part 13 (i.e., the left side of the valve body 1), and a bypass flow channel 151 is provided in the bypass valve part 15, and the bypass flow channel 151 can selectively connect the first chamber 1102 and the second chamber 1103. When the main valve chamber 1101 is connected to the first chamber 1102, when the heat exchange structure 300 is dry-burned due to lack of water, the water in the first chamber 1102 can flow through the bypass flow channel 151 and the second chamber 1103, the heat exchange connecting flow channel 1002, and the first heat exchange water inlet flow channel 131 to the heat exchange channel 310, so as to avoid damage to the heat exchange structure 300 due to dry-burning due to lack of water.

[0088] In this embodiment, the axis of the bypass valve portion 15 is inclined relative to the axis of the three-way valve portion 11, and the bypass plug 153 on the bypass port 152 is arranged forward, so that it is convenient for the operator to open the bypass plug 153 when inspecting the bypass valve portion 15, and there is no need to remove the entire water outlet valve 100 from the heat exchange structure 300. This is convenient and quick, and can reduce the maintenance workload of the operator and reduce labor costs.

[0089] It should be noted that, in this embodiment, since the bypass valve portion 15 is connected to the left side of the three-way valve portion 11, the first valve portion 13 is located on the right side of the three-way valve portion 11, and the extended valve portion 12 is located at the lower part of the three-way valve portion 11, therefore, in this example, the hot water inlet 1111 is opened at the top of the three-way valve portion 11, making full use of the space of the three-way valve portion 11 in all directions to achieve the optimization of the spatial layout of the entire system.

[0090] Embodiment 3

[0091] 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.

[0092] Figure 14 FIG. 1 shows a schematic diagram of the structure of the water outlet valve 100 provided in this embodiment. Figure 14 Combined with Figure 1 As shown, 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 further reduced, and when assembling the wall-mounted boiler water system, only a space for connecting the connecting pipe 600 and the hot water outlet 201 of the combustion chamber 200 needs to be reserved between the combustion chamber 200 and the top of the valve body 1.
