Description
本發明是關於一種具備將熱水導入熱水與冷水的混合比可自由調節之冷熱水調節閥的熱水道，及將冷水導入冷熱水調節閥的冷水道的流體控制裝置。The invention relates to a fluid control device for a hot water passage with a hot water regulating valve for leading hot water into the hot water and cold water with a freely adjustable mixing ratio, and a cold water passage for leading cold water into the cold and hot water regulating valve.
以往，具備：設置在浴室等，熱水與冷水的混合比可自由調節的冷熱水調節閥；設置在冷熱水調節閥的下游的水栓；及水龍頭的流體控制裝置(例如，參閱日本專利特開2010-96296)。Conventionally, there are: a cold and hot water regulating valve installed in a bathroom, etc., and the mixing ratio of hot water and cold water can be freely adjusted; a faucet disposed downstream of the cold and hot water regulating valve;
[發明所欲解決之課題][Problems to be Solved by the Invention]
習知的流體控制裝置是將水栓配置在冷熱水調節閥的下游，所以即使關閉水栓水壓仍就施加於冷熱水調節閥。因此，要求冷熱水調節閥具備可耐水壓的強度，會阻礙冷熱水調節閥之製造成本的低廉化。In the known fluid control device, the water cock is arranged downstream of the cold and hot water regulating valve, so even if the water cock is closed, the water pressure is still applied to the cold and hot water regulating valve. Therefore, requiring the hot and cold water regulating valve to have strength capable of withstanding water pressure hinders the reduction of the manufacturing cost of the cold and hot water regulating valve.
本發明是鑒於以上的點，提供一種可謀求冷熱水調節閥的製造成本之低廉化的流體控制裝置為目的。In view of the above points, the present invention aims to provide a fluid control device capable of reducing the manufacturing cost of a cold/hot water regulating valve.
[1] 為達成上述目的，本發明的流體控制裝置(例如，實施形態的流體控制裝置1。以下相同。)，其特徵為，具備： 將上述熱水導入熱水與冷水的比例可自由調節之冷熱水調節閥(例如，實施形態的冷熱水調節閥2。以下相同。)的熱水道(例如，實施形態的熱水道3。以下相同。)； 將上述冷水導入上述冷熱水調節閥的冷水道(例如，實施形態的冷水道4。以下相同。)； 可自由阻止透過上述熱水道朝上述冷熱水調節閥供應上述熱水的熱水側開關閥(例如，實施形態的熱水側開關閥5。以下相同。)；及 可自由阻止透過上述冷水道朝上述冷熱水調節閥供應上述冷水的冷水側開關閥(例如，實施形態的冷水側開關閥6。以下相同。)。[1] In order to achieve the above object, the fluid control device of the present invention (for example, the fluid control device 1 of the embodiment. The same applies below.) is characterized by comprising: The above-mentioned hot water is introduced into the hot water channel (for example, the hot water channel 3 of the embodiment. The following is the same.) of the cold and hot water regulating valve (for example, the cold and hot water regulating valve 2 of the embodiment. The following is the same.) whose ratio of hot water and cold water can be adjusted freely; The above-mentioned cold water is introduced into the cold water channel of the above-mentioned hot and cold water regulating valve (for example, the cold water channel 4 of the embodiment. The following is the same.); A hot water on/off valve (for example, the hot water on/off valve 5 of the embodiment. The same applies below.) that can freely prevent the hot water from being supplied to the cold and hot water regulating valve through the hot water channel; and A cold water on/off valve (for example, the cold water on/off valve 6 of the embodiment. The same applies hereinafter) that can freely block the supply of the cold water to the hot and cold water regulating valve through the cold water channel.
根據本發明，由於熱水側開關閥與冷水側開關閥是設置在冷熱水調節閥的上游側，所以關閉熱水側開關閥與冷水側開關閥時，對冷熱水調節閥不施加熱水的壓力。因此，如以往，與在熱水的壓力的影響下較長時間曝露的比較，冷熱水調節閥要求較低的耐久性即可，可提供抑制冷熱水調節閥之製造成本的流體控制裝置。According to the present invention, since the hot water on-off valve and the cold water on-off valve are arranged on the upstream side of the cold and hot water regulating valve, when the hot water on-off valve and the cold water on-off valve are closed, no hot water pressure is applied to the cold and hot water regulating valve. Therefore, as compared with conventionally exposed to the influence of hot water pressure for a long time, the cold and hot water regulating valve requires less durability, and it is possible to provide a fluid control device that suppresses the manufacturing cost of the cold and hot water regulating valve.
[2] 又，本發明中，具備： 在上述冷熱水調節閥的上游側連接上述熱水道與上述冷水道的連接部(例如，實施形態的連接部7。以下相同。)，及 在上述連接部以阻止上述熱水與上述冷水混流的方式自由滑動且液密地設置於上述連接部的活塞(例如，實施形態的活塞8。以下相同。)， 上述冷水側開關閥是連接於上述活塞， 在上述熱水側開關閥進行開閥將上述熱水從上述熱水道供應至上述冷熱水調節閥的場合，藉上述熱水道內的上述熱水的壓力在上述連接部內使上述活塞朝著冷水道側移動，進行連接於上述活塞之上述冷水側開關閥的開閥， 在上述熱水側開關閥進行閉閥阻止從上述熱水道朝上述冷熱水調節閥供應熱水的場合，藉上述冷水道內的上述水的壓力在上述連接部內使上述活塞朝著熱水道側移動，進行連接於上述活塞之上述冷水側開關閥的閉閥所構成。[2] Also, in the present invention, it has: A connecting portion (for example, the connecting portion 7 of the embodiment. The same applies below.) connecting the hot water channel and the cold water channel to the upstream side of the hot and cold water regulating valve, and A piston (for example, the piston 8 of the embodiment. The same applies below.) is freely slidable and liquid-tightly provided on the connection portion so as to prevent the mixing of the hot water and the cold water, The above-mentioned cold water side switch valve is connected to the above-mentioned piston, When the hot water side on-off valve is opened to supply the hot water from the hot water channel to the cold and hot water regulating valve, the piston is moved toward the cold water channel in the connecting portion by the pressure of the hot water in the hot water channel, and the cold water side on-off valve connected to the piston is opened, When the hot water side on-off valve is closed to prevent the supply of hot water from the hot water channel to the cold and hot water regulating valve, the pressure of the water in the cold water channel moves the piston toward the hot water channel in the connecting portion, and the cold water side on-off valve connected to the piston is closed.
根據本發明，藉著熱水側開關閥的閉閥，可與此連動進行冷水側開關閥的開關。藉此，利用人沒有進行熱水側開關閥與冷水側開關閥的兩個閥之開關的必要，可以一個閥操作進行兩個開關閥操作，使開關操作變得容易。According to the present invention, by closing the hot water side on/off valve, the cold water side on/off valve can be opened and closed in conjunction with this. Thereby, the user does not need to open and close the two valves of the hot water side on-off valve and the cold water side on-off valve, and the two on-off valves can be operated with one valve operation, making the on-off operation easy.
[3] 又，本發明中，設：上述連接部之中的至少上述活塞滑動之部分的直徑為第1直徑φA、上述冷水道之中以上述冷水側開關閥進行閉閥之部分的直徑為第2直徑φB、上述熱水道的上述熱水的壓力為Ph1、上述冷水道之中較上述冷水側開關閥更上游側的上述冷水的壓力為Pc1、上述冷水道之中較上述冷水側開關閥更下游側的冷水的壓力為Pc2， 在通水時，以下式(1)成立的方式，設定上述第1直徑φA與上述第2直徑φB為佳。[3] In the present invention, the diameter of at least the portion where the piston slides in the connecting portion is the first diameter φA, the diameter of the portion of the cold water channel where the valve is closed by the cold water side on-off valve is the second diameter φB, the pressure of the hot water in the hot water channel is Ph1, the pressure of the cold water on the upstream side of the cold water side on-off valve in the cold water channel is Pc1, and the pressure of the cold water on the downstream side of the cold water side on-off valve in the above-mentioned cold water channel is Pc2. When passing water, it is preferable to set the first diameter φA and the second diameter φB so that the following formula (1) holds.
[4] 又，本發明的流體控制裝置是在上述熱水道及上述冷水道的下游連接有上述冷熱水調整閥。根據本發明，如以往，與在冷熱水的壓力的影響下較長時間曝露的比較，冷熱水調節閥要求較低的耐久性即可，可提供抑制冷熱水調節閥之製造成本的流體控制裝置。[4] In addition, in the fluid control device of the present invention, the hot water regulating valve is connected downstream of the hot water channel and the cold water channel. According to the present invention, the cold and hot water regulating valve requires less durability than conventionally exposed to the influence of cold and hot water pressure for a long time, and a fluid control device that suppresses the manufacturing cost of the cold and hot water regulating valve can be provided.
[第1實施形態] 參與第1圖及第2圖，說明本發明的第1實施形態的流體控制裝置1。第1實施形態的流體控制裝置1具備：冷熱水調節閥2；將供熱水器(省略圖示)等所供應的熱水導入冷熱水調節閥2的熱水道3；將從自來水管(省略圖示)等的冷水導入冷熱水調節閥2的冷水道4；可自由阻止透過熱水道3朝冷熱水調節閥2供應熱水的熱水側開關閥5；及可自由阻止透過冷水道4朝冷熱水調節閥2供應冷水的冷水側開關閥6。[First Embodiment] Referring to Figs. 1 and 2, a fluid control device 1 according to a first embodiment of the present invention will be described. The fluid control device 1 of the first embodiment includes: a cold and hot water regulating valve 2; a hot water channel 3 for introducing hot water supplied by a water heater (not shown) or the like into the cold and hot water regulating valve 2; a cold water channel 4 for introducing cold water from a water pipe (not shown in the figure) etc. into the cold and hot water regulating valve 2;
冷熱水調節閥2是對應在內部流動的熱水之混合水的溫度變化使用彈力變化的感溫致動器(省略圖示)來移動閥體(省略圖示)藉以使熱水流入口(省略圖示)與冷水流入口(省略圖示)的開口面積的比例變化，將混合水的溫度維持在預定的溫度。The cold and hot water regulating valve 2 uses a temperature-sensitive actuator (not shown) with elastic force to move the valve body (not shown) in response to the temperature change of the mixed water of hot water flowing inside, so as to change the ratio of the opening area of the hot water inlet (not shown) to the cold water inlet (not shown), and maintain the temperature of the mixed water at a predetermined temperature.
熱水道3與冷水道4在冷熱水調節閥2的上游側設有連接熱水道3與冷水道4的管狀的連接部7。在連接部7，將連接部7阻止冷熱水混流的活塞部8自由滑動且液密地設置在連接部7內。冷水側開關閥6與活塞8被以連結棒9所連接。The hot water channel 3 and the cold water channel 4 are provided with a tubular connecting portion 7 connecting the hot water channel 3 and the cold water channel 4 on the upstream side of the hot and cold water regulating valve 2 . In the connection part 7, the piston part 8 which prevents the connection part 7 from mixing cold and hot water is freely slidable and liquid-tightly provided in the connection part 7. The cold water side switch valve 6 and the piston 8 are connected by a connecting rod 9 .
在此，進行以下定義：連接部7之中的至少活塞8滑動的部分的直徑為第1直徑φA、冷水道4之中以冷水側開關閥6閉閥的部分的直徑為第2直徑φB、熱水道3的熱水的壓力為Ph1、冷水道4之中比冷水側開關閥6上游側的冷水的壓力為Pc1、冷水道4之中比冷水側開關閥6下游側的冷水的壓力為Pc2。Here, the following definitions are made: the diameter of the portion where at least the piston 8 slides in the connecting portion 7 is the first diameter φA; the diameter of the portion of the cold water channel 4 where the cold water side on-off valve 6 is closed is the second diameter φB; the pressure of the hot water in the hot water channel 3 is Ph1;
第1直徑φA與第2直徑φB是以在通水時(熱水與冷水供應至冷熱水調節閥2時)，以下式(1)成立的方式所設定。The first diameter φA and the second diameter φB are set so that the following equation (1) holds when water is passed (when hot water and cold water are supplied to the hot and cold water regulating valve 2 ).
。 .
具體的第1直徑φA與第2直徑φB會根據獨立式房屋或大廈等變更熱水道3的熱水的壓力Ph1、冷水道4之壓力Pc1的值，因此藉Ph1、Pc1適當設計。並且，冷水側開關閥6本身雖比第2直徑φB大但是較第2直徑φB更徑向外側的部分是從第1圖的上下方向施加Pc2的壓力而抵消，因此冷水側開關閥6的大小對式(1)並不會造成影響。再者，圖式中，黑箭頭是表示熱水的流動，塗成白色的箭頭是表示冷水的流動，帶有斜線的箭頭是表示熱水與冷水之混合水的流動。Specifically, the first diameter φA and the second diameter φB will change the values of the hot water pressure Ph1 of the hot water channel 3 and the pressure Pc1 of the cold water channel 4 according to detached houses or buildings, so they are appropriately designed by Ph1 and Pc1. In addition, although the cold water side on-off valve 6 itself is larger than the second diameter φB, the radially outer portion of the second diameter φB is offset by the pressure Pc2 applied from the up and down direction in FIG. Furthermore, in the drawings, the black arrows represent the flow of hot water, the white arrows represent the flow of cold water, and the arrows with oblique lines represent the flow of mixed water of hot water and cold water.
如第1圖表示，將熱水側開關閥5開閥從熱水道3供應熱水至冷熱水調節閥2時，藉熱水道3內的熱水的壓力Ph1在連接部7內使活塞8在冷水道4側滑動．移動，將透過連結棒9連接於活塞8的冷水側開關閥6開閥。As shown in Figure 1, when the on-off valve 5 on the hot water side is opened to supply hot water from the hot water channel 3 to the cold and hot water regulating valve 2, the piston 8 slides on the side of the cold water channel 4 in the connection part 7 by the pressure Ph1 of the hot water in the hot water channel 3. Move, the cold water side switching valve 6 connected to the piston 8 through the connecting rod 9 is opened.
又，本實施形態中，例如，在熱水道3流動的熱水的壓力Ph1變大時，活塞8更進一步強力推壓，所以冷水側開關閥6也開得更大。因此，熱水的壓力Ph1變大時，使得較冷水道4之中的冷水側開關閥6下游側的水的壓力Pc2變大。亦即，本實施形態的流體控制裝置1也兼具有調整供應至冷熱水調節閥2之熱水的壓力Ph1與冷水的壓力Pc2之平衡的冷熱水壓力均衡功能。In addition, in this embodiment, for example, when the pressure Ph1 of the hot water flowing in the hot water channel 3 increases, the piston 8 is further strongly pressed, so the cold water side on-off valve 6 is also opened more. Therefore, when the pressure Ph1 of the hot water increases, the pressure Pc2 of the water downstream of the cold water side on-off valve 6 in the relatively cold water channel 4 increases. That is, the fluid control device 1 of the present embodiment also has a hot and cold water pressure equalization function for adjusting the balance between the pressure Ph1 of hot water supplied to the hot water regulating valve 2 and the pressure Pc2 of cold water.
如第2圖表示，將熱水側開關閥5閉閥阻止從熱水道3朝冷熱水調節閥2之熱水的供應時，藉著冷水道4內的冷水的水壓Pc1在連接部7內使活塞8朝向熱水道3側移動，將連接於活塞8的冷水側開關閥6以(φA-φB)×PC1的力進行閉閥。As shown in Fig. 2, when the hot water side on-off valve 5 is closed to stop the supply of hot water from the hot water channel 3 to the cold and hot water regulating valve 2, the piston 8 is moved toward the hot water channel 3 in the connection part 7 by the hydraulic pressure Pc1 of the cold water in the cold water channel 4, and the cold water side on-off valve 6 connected to the piston 8 is closed with a force of (φA-φB)×PC1.
根據本實施形態的流量控制裝置1，由於將熱水側開關閥5與冷水側開關閥6設置在冷熱水調節閥2的上游側，所以在關閉熱水側開關閥5與冷水側開關閥6時，對冷熱水調節閥2不施加熱水的壓力。因此，如以往，與在熱水的壓力的影響下較長時間曝露的比較，冷熱水調節閥2要求較低的耐久性即可，可提供抑制冷熱水調節閥2之製造成本的流體控制裝置1。According to the flow control device 1 of this embodiment, since the hot water side on-off valve 5 and the cold water side on-off valve 6 are provided on the upstream side of the cold and hot water regulating valve 2, when the hot water side on-off valve 5 and the cold water side on-off valve 6 are closed, no pressure of hot water is applied to the cold and hot water regulating valve 2. Therefore, as in the past, less durability is required for the cold/hot water regulating valve 2 compared with exposure to the influence of hot water pressure for a long time, and it is possible to provide the fluid control device 1 that suppresses the manufacturing cost of the cold/hot water regulating valve 2 .
又，本實施形態中，熱水側開關閥5一旦開閥時與此連動也使得冷水側開關閥6開閥，熱水側開關閥5閉閥時與此連動也使得冷水側開關閥6閉閥。藉此，利用者沒有進行熱水側開關閥5與冷水側開關閥6之兩個閥開關的必要，可以一個閥的操作進行兩個開關閥5、6的操作，使開關操作變得容易。Also, in this embodiment, once the hot water side switch valve 5 is opened, the cold water side switch valve 6 is opened in conjunction with it, and when the hot water side switch valve 5 is closed, the cold water side switch valve 6 is also closed in conjunction with this. Thereby, the user does not need to open and close two valves of the hot water side on-off valve 5 and the cold water side on-off valve 6, and can operate the two on-off valves 5, 6 with one valve operation, making the on-off operation easy.
又，一般在冷水的壓力與熱水的壓力為冷水的壓力一方較大，如以往在冷熱水調節閥2的下游設置水栓的場合，設置阻止冷水朝著熱水道3逆流的止回閥。但是，根據本實施形態的流體控制裝置1，不在冷熱水調節閥2的下游測設置水栓而成常時地開放，因此冷水不會朝著熱水道3逆流，沒有如以往設置止回閥的必要而可謀求構成的簡略化。Also, generally the pressure of the cold water and the pressure of the hot water are higher than the pressure of the cold water. For example, when a water plug is installed downstream of the cold and hot water regulating valve 2 in the past, a check valve is installed to prevent the cold water from flowing backward toward the hot water channel 3 . However, according to the fluid control device 1 of the present embodiment, the water tap is not provided downstream of the hot and cold water regulating valve 2, but is always open, so cold water does not flow back toward the hot water channel 3, and there is no need to provide a check valve as in the past, and the structure can be simplified.
[第2實施形態] 第3圖表示本發明的第2實施形態的流體控制裝置1。第2實施形態的流體控制裝置1未設有第1實施形態的連接部7、活塞8、連結棒9，冷水側開關閥6並未與熱水側開關閥5連動，除了有單獨進行開關操作的必要的點，與第1實施形態相同的構成，針對相同的構成賦予相同的符號並省略說明。[Second Embodiment] Fig. 3 shows a fluid control device 1 according to a second embodiment of the present invention. The fluid control device 1 of the second embodiment is not provided with the connection part 7, the piston 8, and the connecting rod 9 of the first embodiment, and the cold water side on-off valve 6 is not interlocked with the hot water side on-off valve 5, except for the point where an on-off operation is performed independently, and the same configuration as the first embodiment, the same symbols are assigned to the same configuration, and descriptions are omitted.
根據本實施形態的流體控制裝置1，在冷熱水調節閥2的上游側設有熱水側開關閥5與冷水側開關閥6，所以在關閉熱水側開關閥5與冷水側開關閥6時，如第3圖表示的耐壓範圍，與第1實施形態的流體控制裝置1同樣，在開關閥5，6閉閥的狀態，熱水的壓力是僅加至熱水側開關閥5、冷水側開關閥6，對冷熱水調節閥2不施加熱水的壓力。因此，如以往，與在熱水的壓力的影響下較長時間曝露的比較，冷熱水調節閥2要求較低的耐久性即可，可提供抑制冷熱水調節閥2之製造成本的流體控制裝置1。According to the fluid control device 1 of this embodiment, the hot water side on-off valve 5 and the cold water side on-off valve 6 are provided on the upstream side of the cold and hot water regulating valve 2, so when the hot water side on-off valve 5 and the cold water side on-off valve 6 are closed, as shown in FIG. Therefore, as in the past, less durability is required for the cold/hot water regulating valve 2 compared with exposure to the influence of hot water pressure for a long time, and it is possible to provide the fluid control device 1 that suppresses the manufacturing cost of the cold/hot water regulating valve 2 .
根據本實施形態的流體控制裝置1，在熱水道3設有熱水側開關閥5，因此冷水不會逆流至熱水道3，如以往沒有設置止回閥的必要而可謀求構成的簡略化。According to the fluid control device 1 of the present embodiment, since the hot water side on-off valve 5 is provided in the hot water channel 3, the cold water does not flow back into the hot water channel 3, and the structure can be simplified as conventionally without the need for a check valve.
[比較例] 第4圖是表示作為比較例的流體控制裝置1’。比較例的流體控制裝置1’中，在冷熱水調節閥2的下游設有水栓11(5’、6’)。因此，如第4圖表示在耐壓範圍內包含有冷熱水調節閥2，冷熱水調節閥2有具備可耐水壓程度之強度的必要，冷熱水調節閥2的低廉化有所限制。[comparative example] Fig. 4 shows a fluid control device 1' as a comparative example. In the fluid control device 1' of the comparative example, water taps 11 (5', 6') are provided downstream of the hot and cold water regulating valve 2. Therefore, as shown in FIG. 4 , the cold and hot water regulating valve 2 is included in the pressure-resistant range, and the cold and hot water regulating valve 2 needs to have strength to withstand water pressure, and the cost reduction of the cold and hot water regulating valve 2 is limited.
又，如本比較例，在冷熱水調節閥2’的下游設置水栓11的場合，有設置阻止冷水道4’的冷水朝熱水道3’，或使熱水道3’的熱水朝冷水道4’逆流之止回閥12的必要。Also, as in this comparative example, in the case where the water cock 11 is installed downstream of the cold and hot water regulating valve 2', it is necessary to set the check valve 12 that prevents the cold water from the cold water channel 4' from flowing toward the hot water channel 3', or the hot water from the hot water channel 3' from flowing backwards towards the cold water channel 4'.
