Japanese Patent Laid-Open No. 9-276678

  In the fluid mixer configured as described in Patent Document 1, the mixing effect varies depending on the direction of the opening around the axis of the pipe. Therefore, when installing the fluid mixer, it is necessary to adjust the direction of the opening so that the mixing effect is appropriate. However, in the fluid mixer configured as described in Patent Document 1, since the stirring member is disposed in the pipe, the direction of the opening formed in the stirring member cannot be confirmed from the outside of the pipe. Therefore, when installing the fluid mixer, it was necessary to install the fluid mixer after confirming the direction of the opening by a method such as looking into the pipe. As a result, there has been a problem that work for installing the fluid mixer becomes complicated and work efficiency is lowered. The problem is not limited to the fluid mixer that mixes the fluid by allowing the fluid to pass through the stirring member having an opening, but is common in the fluid mixer in which the mixing effect varies depending on the direction of the stirring member around the axis of the pipe line. It is a problem that occurs.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a fluid mixer that can improve the work efficiency of installation work with a simple configuration.

  The fluid mixer according to the present invention that achieves the above object includes a flow member that is formed in a tubular shape and includes a flow path that allows the fluid to flow, and a stirring member that stirs the fluid. A first mark indicating at least the direction of the stirring member around the flow axis of the flow member is provided on the outer peripheral surface of the flow member.

  The fluid mixer of the present invention includes a flow member that is formed in a tubular shape and includes a flow path that allows a fluid to flow, and a stirring member that stirs the fluid. And the 1st mark which shows at least the direction of the stirring member around the flow-path axis line of a distribution member is provided in the outer peripheral surface of a distribution member. By configuring the fluid mixer in this way, the direction of the stirring member around the axis of the flow member can be confirmed by visually recognizing the first mark. Thereby, when installing a fluid mixer, the direction of the stirring member around the axial line of the flow member can be appropriately adjusted without directly viewing the stirring member. Therefore, the work efficiency of the installation work can be improved with a simple configuration.

FIG. 2 is a cross-sectional view of the fluid mixer 10 as seen from the 2-2 direction shown in FIG.

  The fluid mixer 10 allows the fluid to pass through the slit 12b having a smaller area compared to the cross-sectional area of the flow path R in a state where the flow velocity is accelerated, and generates the vortex on the downstream side of the slit 12b. Stir.

  As shown in FIGS. 1 and 2, the fluid mixer 10 includes a flow member 11 that is formed in a tubular shape and includes a flow path R through which a fluid flows, and a stirring member 12 that stirs the fluid. A first mark 13 indicating the direction of the stirring member 12 around the flow path axis Z of the flow member 11 is provided on the outer peripheral surface of the flow member 11.

  The flow member 11 is formed in a cylindrical shape in the present embodiment, and includes a stirring member 12 on an inner peripheral surface thereof. The flow member 11 can be formed integrally with the stirring member 12 by cutting one member. The flow member 11 can be formed integrally with the stirring member 12 by a molding process such as injection molding. On the other hand, the flow member 11 can join the stirring member 12 formed separately to the inner wall 11a using an adhesive. The flow member 11 can join the stirring member 12 formed separately to the inner wall 11a by welding. The flow member 11 can assemble the stirring member 12 formed separately to the inner wall 11a by press fitting.

  The material of the flow member 11 can be appropriately selected according to the environment such as fluid pressure and temperature, or the fluid characteristics such as corrosiveness. When the distribution member 11 is made of a resin, a fluorine-based resin such as polyvinyl chloride, polypropylene, polytetrafluoroethylene, polyvinylidene fluoride, and a tetrafluoro / perfluoroalkyl vinyl ether copolymer resin is used. When the flow member 11 is made of metal, stainless steel, iron, copper, aluminum, titanium, or the like is used. In addition, the distribution member 11 may be made of glass or earthenware.

  The stirring member 12 is disposed in the pipe of the flow member 11 so as to cross the flow path axis Z, and is formed in a plate shape and has an opening (slit 12b) through which fluid passes. The length and width of the opening 12b can be arbitrarily set as long as the fluid passes through in an accelerated state and the fluid is stirred while generating a vortex on the downstream side of the opening 12b.

  The mixing effect required for mixing the fluid differs depending on the intended use of the mixed fluid. The method for evaluating the mixing effect varies depending on the situation. For example, in a fluid in which a plurality of types of fluids are mixed, the mixing effect can be evaluated by how much the plurality of types of fluids are mixed. In mixing the fluid by the fluid mixer 10, the mixing effect varies depending on the direction of the stirring member 12 around the flow path axis Z of the flow member 11. Specifically, the mixing effect varies depending on the direction of the opening 12 b around the flow path axis Z of the flow member 11. The direction of the opening 12b around the flow path axis Z of the flow member 11 means the direction around the flow path axis Z of a plane including the flow path axis Z and the opening 12b of the flow member 11.

(Embodiment 2)
The fluid mixer 210 will be described with reference to FIGS. 4 and 5.

  FIG. 4 is a perspective view showing a fluid mixer 210 according to the second embodiment. FIG. 4 shows a state in which the agitation member 212 is allowed to pass through the flow member 211 that constitutes the fluid mixer 210. FIG. 5 is a cross-sectional view of the fluid mixer 210 as seen from the direction 5-5 shown in FIG.

  The fluid mixer 210 according to the second embodiment is different from the fluid mixers 10, 20, 30, and 40 according to the first embodiment and the modifications thereof in the following points. That is, the marks (first marks 13, 23, 43, second marks 34, 44, third marks 45, and fourth marks 46) of the fluid mixers 10, 20, 30, and 40 according to the first embodiment and the modifications thereof. Was directly provided on the outer peripheral surface of the flow member 11. On the other hand, the mark (the first mark 213 and the second mark 214) of the fluid mixer 210 according to the second embodiment is provided on a seat portion 217 formed to protrude from the outer peripheral surface of the flow member 211.

  A configuration related to the above-described difference will be described below. The same components as those of the fluid mixer 10 according to the first embodiment are denoted by the same reference numerals and description thereof is omitted. In the present embodiment, the case where the first mark 213 and the second mark 214 are provided on the seat 217 will be described. In addition to the first mark 213 and the second mark 214, the above-described modification 3 of the first embodiment is described above. Marks corresponding to the third mark 45 and the fourth mark 46 may be provided on the seat portion 217.

  Similar to the fluid mixer 10, the fluid mixer 210 allows the fluid to pass through the slit 212b having a smaller area compared to the cross-sectional area of the flow path R in a state where the flow velocity is accelerated, and the fluid is passed through the slit 212b. Stirring while generating vortices on the downstream side.

  As shown in FIGS. 4 and 5, the fluid mixer 210 includes a flow member 211 that is formed in a tubular shape and includes a flow path R through which a fluid flows, and a stirring member 212 that stirs the fluid. The fluid mixer 210 is configured to be connectable to other piping members. A first mark 213 indicating at least the direction of the stirring member 212 around the flow path axis of the flow member 211 is provided on the outer peripheral surface of the flow member 211. Moreover, the flow direction is set for each fluid mixer 210 in the fluid mixer 210 as in the second modification of the first embodiment. A second mark 214 indicating the flow direction set for each fluid mixer 210 is formed as at least a part of the first mark 213 on the outer peripheral surface of the flow member 211. In the present embodiment, the second mark 214 is formed integrally with the first mark 213.

  The flow member 211 is formed in a cylindrical shape, for example, and includes a stirring member 212 on its inner peripheral surface.

  The flow member 211 is configured such that both end portions can be freely inserted into other piping members.

  A seat 217 is provided on the outer peripheral surface of the flow member 211 so as to protrude from the outer peripheral surface of the flow member 211. Specifically, the seat portion 217 is provided between the end portions of other piping members into which the both end portions of the flow member 211 are inserted. More specifically, the seat portion 217 is provided in an annular shape on the outer peripheral surface of the flow member 211. More specifically, the seat portion 217 is provided in the central portion of the flow member 211 in the flow channel axis Z direction. The outer peripheral surface of the seat portion 217 forms a part of the outer peripheral surface of the flow member 211.

  The height H of the seat 217 can be set as appropriate. For example, the height H of the seat portion 217 is the distance from the flow path axis Z of the flow member 211 to the outer peripheral surface of the seat portion 217 and the outer peripheral surfaces of other piping members connected to both ends of the flow member 211. The distance can be set to be equal. Thereby, when the end surface of another piping member is made to contact | abut to the side surface of the seat part 217, a level | step difference does not arise between the outer peripheral surface of the seat part 217, and the outer peripheral surface of another piping member. Therefore, another piping member can be connected to the flow member 211 without causing a discontinuous portion between the ends of the other piping members connected to both ends of the flow member 211.

  Moreover, the distance L from the side surface of the seat portion 217 to both ends of the flow member 211 can be set as appropriate. For example, the distance L from the side surface of the seat portion 217 to both ends of the flow member 211 can be set to be the same as or shorter than the insertion depth of the piping member connected to both ends of the flow member 211. Thereby, in the state where the piping member was connected to the both ends of the flow member 211, the total length of the piping system including the fluid mixer 210 and the piping member can be shortened. At this time, the both end portions of the flow member 211 have a distance L from the side surface of the seat portion 217 to both ends of the flow member 211 by the end surfaces of the piping members connected to the both end portions coming into contact with the side surfaces of the seat portion 217. It is not inserted into the piping member beyond that. That is, the seat portion 217 functions as a stopper when another piping member is connected to the flow member 211.

  As long as at least the outer peripheral surface of the flow member 211 is dissolved in an adhesive that dissolves and adheres the synthetic resin, the material of the flow member 211 depends on the environment such as fluid pressure and temperature, or fluid characteristics such as corrosiveness. It can be selected appropriately. In the present embodiment, the entire distribution member 211 is made of polyvinyl chloride.

  The connection between the both ends of the flow member 211 and the other piping members can be performed by, for example, TS connection. TS connection is a connection method in which the end of one synthetic resin pipe member is fitted and connected to the inside of the end of another synthetic resin pipe member. Specifically, first, an adhesive that dissolves and bonds the synthetic resin is applied to the outer peripheral surface of the end of one piping member. If it is left for a while after application | coating, the outer peripheral surface of the edge part of one piping member will melt | dissolve in the said adhesive agent. Thereafter, the end of one pipe member coated with the adhesive is fitted inside the end of another pipe member coated with the adhesive on the inner peripheral surface of the end. When the synthetic resin constituting the outer peripheral surface of one piping member and the inner peripheral surface of another piping member dissolved in the adhesive is solidified again, the end of one piping member and the end of the other piping member are integrated. Connected.

  In the present embodiment, the flow member 211 is configured such that both end portions can be freely inserted into other piping members. At least the outer peripheral surface of the flow member 211 is dissolved in an adhesive that dissolves and adheres the synthetic resin. Thereby, both ends of the distribution member 211 function as a TS connection outlet. That is, the TS connection can be suitably used for the connection between the fluid mixer 210 and other piping members.

  The stirring member 212 is disposed in the pipe of the flow member 211 so as to intersect with the flow path axis Z, and has an opening (slit 212b) that is formed in a plate shape and allows fluid to pass therethrough.

  The stirring member 212 includes a plate-shaped main body 212a provided with an opening (slit 212b). The main body 212a is composed of a pair of members having the same shape, and a slit 212b is provided therebetween. The stirring member 212 is formed by refracting the end 212a2 of the stirring member 212 formed in the region of the radial end Rb of the flow path R on the upstream side and the downstream side of the flow path axis Z. The upstream end portion 212a2 is refracted toward the downstream side, and the downstream end portion 212a2 of the flow path axis Z is refracted toward the upstream side.

  The main body 212a forms end portions 212a2 from both ends along the first radial direction X of the central portion 212a1. That is, in the stirring member 212, the central portion 212a1 of the main body 212a is formed in the region of the radial center portion Rc of the flow channel R, and the end portion 212a2 of the main body 212a is formed in the region of the radial end portion Rb of the flow channel R. ing. An end portion 212a2 on the upstream side of the flow path axis Z is refracted toward the central portion 212a1 toward the downstream side. An end portion 212a2 on the downstream side of the flow path axis Z is refracted with respect to the central portion 212a1 toward the upstream side. The refraction angle of the end portion 212a2 with respect to the central portion 212a1 can be arbitrarily set as long as the fluid passes through in an accelerated state and the fluid is stirred while generating a vortex on the downstream side of the slit 212b.

  In the present embodiment, the central portion 212a1 of the stirring member 212 is disposed at the central portion in the flow channel axis Z direction of the flow member 211.

  The material of the stirring member 212 can be appropriately selected according to the environment such as fluid pressure and temperature, or the fluid characteristics such as corrosiveness. For example, the stirring member 212 can be formed of the material described in Embodiment 1 as a material that can be used for the flow member 11. The shapes of the central portion 212a1 and the end portion 212a2 of the stirring member 212 only have to be formed in a plate shape as a whole, and are not limited to flat plates without undulations. For example, a corrugated plate having a corrugated cross section or a curved plate may be used.

  When the flow member 211 and the stirring member 212 are formed of the same material, the flow member 211 and the stirring member 212 are formed by molding such as cutting or injection molding as described above in the first embodiment as a method of forming the flow member 11. Can be formed integrally. On the other hand, when the flow member 211 and the stirring member 212 are formed of different materials, as described above in the first embodiment as a method of forming the flow member 11, the separately formed stirring member 212 is adhesive, welded, and the like. Alternatively, the flow member 211 may be formed by joining to the inner wall 211a using press-fitting or the like.

In the present embodiment, the shape of the second mark 214 is set in the same manner as the second mark 34 of the fluid mixer 30 according to the second modification of the first embodiment. That is, taking the case of FIG. 4 as an example, the second mark 214 indicates that the flow direction is set in the direction of the arrow indicated by Z.

  When the first mark 213 and the second mark 214 are provided on the outer peripheral surface of the seat portion 217, when the end of the flow member 211 is inserted and connected to the inside of the end of another piping member, the other connected The first mark 213 and the second mark 214 are not covered by the end of the piping member. Thereby, even after the fluid mixer 210 is connected to another piping member and installed, the first mark 213 and the second mark 214 can be visually recognized.

  In addition, as described above in the first embodiment, the mixing effect required for mixing the fluid differs depending on the use application of the mixed fluid.

Thereby, by visually recognizing the first mark 213, the inclination direction of the stirring member 212 can be confirmed. Specifically, the stirring member 212 is inclined so that the distance between the outer peripheral surface of the flow member 211 on the side where the first mark 213 is provided and the stirring member 212 becomes narrower from the upstream side to the downstream side in the flow direction. Can be confirmed. Thereby, when installing the fluid mixer 210, it can install easily so that the inclination direction of the stirring member 212 with respect to a flow direction may become appropriate.

  Furthermore, in the present embodiment, a second mark 214 indicating the flow direction set for each fluid mixer 210 is provided on the outer peripheral surface of the flow member 211. Thereby, by visually recognizing the first mark 213 and the second mark 214, the inclination direction of the stirring member 212 can be easily confirmed without directly viewing the stirring member 212. Therefore, when the fluid mixer 210 is installed, the stirring member 212 can be easily installed so that the inclination direction of the stirring member 212 is appropriate with respect to the flow direction without directly viewing the stirring member 212.

(Embodiment 3)
The fluid mixer 310 will be described with reference to FIGS. 6 and 7.

  FIG. 6 is a perspective view showing a fluid mixer 310 according to the third embodiment. FIG. 7 is a view showing the fluid mixer 310 from above.

  The fluid mixer 310 according to the third embodiment differs from the fluid mixer 10 according to the first embodiment in the following points. That is, the stirring member 12 formed of a plate-like member is installed at an inclination on the flow member 11 of the fluid mixer 10 according to the first embodiment. On the other hand, the flow member 311 of the fluid mixer 310 according to the third embodiment is formed in a shape in which both ends of the plate-like member are twisted in the opposite directions by a predetermined angle around the flow path axis Z of the flow member 311. A plurality of torsion members 312 (corresponding to a stirring member) are disposed adjacent to each other. Further, on the outer peripheral surface of the flow member 11 of the fluid mixer 10 according to the first embodiment, the plane including the flow path axis Z of the flow member 11 and the opening 12b and the outer peripheral surface of the flow member 11 intersect. A first mark 13 was provided. On the other hand, the outer peripheral surface of the flow member 311 of the fluid mixer 310 according to the third embodiment includes a plane including the upstream end of the torsion member 312 disposed on the most upstream side and the flow path axis Z of the flow member 311. And the 1st mark 313 is provided in the part which the outer peripheral surface of the distribution | circulation member 311 crosses.

  A configuration related to the above-described difference will be described below. The same components as those of the fluid mixer 10 according to the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The fluid mixer 310 mixes the fluid flowing through the pipe of the flow member 311 by repeatedly dividing and rotating the fluid by the torsion member 312. In the fluid mixer 310, the flow direction is set for each fluid mixer 310 as in the second modification of the first embodiment.

  As shown in FIGS. 6 and 7, the fluid mixer 310 includes a flow member 311 that is formed in a tubular shape and includes a flow path R through which a fluid flows, and a torsion member 312 that stirs the fluid. A first mark 313 indicating the direction of the torsion member 312 around the flow path axis Z of the flow member 311 is provided on the outer peripheral surface of the flow member 311.

  The flow member 311 is formed in, for example, a cylindrical shape, and includes a torsion member 312 on the inner peripheral surface thereof. Similar to the flow member 11, the flow member 311 can be formed integrally with the torsion member 312 by a molding process such as injection molding. On the other hand, like the flow member 11, the flow member 311 may be formed by joining a torsion member 312 formed separately using an adhesive, welding, press fitting, or the like to the inner wall of the flow member 311.

  For the flow member 311, the same material as that of the flow member 11 can be appropriately selected according to the environment such as fluid pressure and temperature, or fluid characteristics such as corrosiveness.

  Flange 350 is provided at both ends of the flow member 311. An opening 351 is formed in the flange 350. Via the flange 350, the flow member 311 can be connected to the flange portion of the piping member laid on the upstream side and the downstream side of the flow member 211. At this time, a fastener such as a bolt can be passed through the opening 351.

  The torsion member 312 is disposed in a state where the mutually adjacent ends in the longitudinal direction of the torsion members 312 adjacent to each other in the pipe of the flow member 311 intersect each other.

  The material of the torsion member 312 can be appropriately selected depending on the environment such as fluid pressure and temperature, or the fluid characteristics such as corrosiveness. The shape of the torsion member 312 may be any shape as long as both ends of a member formed in a plate shape as a whole are twisted. Here, the plate shape is not limited to a flat plate having no undulations. For example, a corrugated plate having a corrugated cross section or a curved plate may be used.

  By disposing the torsion members 312 in the state where the mutually adjacent ends in the longitudinal direction intersect each other, the fluid flowing in the pipe of the flow member 311 is mixed. Specifically, first, a plurality of types of fluids before being mixed are introduced from the upstream end of the flow member 311. At this time, the plurality of types of fluids are divided into two flows by the end portion in the longitudinal direction of the torsion member installed on the most upstream side of the flow member 311. Then, the two divided flows are rotated around the flow path axis Z of the flow member 311. Another torsion member is installed adjacent to the downstream side of the torsion member installed on the most upstream side of the flow member 311. Then, the downstream end portion of the twisting member installed on the most upstream side and the upstream end portion of the other twisting member in the longitudinal direction are in a state of crossing each other. for that reason. The two flows of the fluid rotated around the flow path axis Z are divided again by the upstream longitudinal end of another torsion member and rotated around the flow path axis Z. The fluid flowing in from the upstream end of the flow member 311 is mixed by repeating the division and rotation by the torsion member.

  The first mark 313 includes a flow path axis Z of the flow member 311 on the outer peripheral surface of the flow member 311 and a plane including the upstream end of the torsion member 312 disposed on the most upstream side, and an outer peripheral surface of the flow member 311. And is provided at the intersection.

  A second mark 314 indicating the flow direction set for each fluid mixer 310 is provided on the outer peripheral surface of the flow member 311. Specifically, the second mark 314 is formed as at least a part of the first mark 313. In the present embodiment, the second mark 314 is formed integrally with the first mark 313. In the present embodiment, the shape of the second mark 314 is set in the same manner as the second mark 34 of the fluid mixer 30 according to the second modification of the first embodiment. 6 and FIG. 7 as an example, the second mark 314 indicates that the flow direction is set in the direction of the arrow indicated by Z.

  In mixing the fluid, an appropriate mixing effect required for the mixed fluid varies depending on the use application of the mixed fluid. When mixing the fluid by the fluid mixer 310, the mixing effect also varies depending on the direction around the flow path axis Z of the flow member 311 at the upstream end of the torsion member 312 installed on the most upstream side. . The direction of the upstream end portion of the torsion member 312 installed on the most upstream side is the longitudinal axis on the upstream side of the flow path axis Z of the flow member 311 and the torsion member 312 installed on the most upstream side. It means the direction around the plane flow path axis Z including the end. When the fluid mixer 310 is installed, it is necessary to appropriately adjust the direction of the upstream end portion of the torsion member 312 installed on the most upstream side so that an appropriate mixing effect can be obtained.

  In the present embodiment, the first mark 313 includes a flow path on the outer circumferential surface of the flow member 311 and a plane including the flow path axis Z of the flow member 311 and the upstream end of the torsion member 312 disposed on the most upstream side. It is provided at a portion where the outer peripheral surface of the member 311 intersects. That is, the first mark 313 is on a plane including the flow path axis Z of the flow member 311 and the upstream end of the torsion member 312 disposed on the most upstream side. A second mark 314 indicating the flow direction set for each fluid mixer 310 is provided on the outer peripheral surface of the flow member 311. Therefore, by visually recognizing the first mark 313 and the second mark 314, the direction of the end portion in the longitudinal direction on the upstream side of the torsion member 312 installed on the most upstream side can be confirmed. Thereby, when installing a fluid mixer, the direction of the edge part of the longitudinal direction of the upstream of the twist member 312 installed in the uppermost stream side can be adjusted appropriately, without visually recognizing the twist member 312.

  According to embodiment mentioned above, there exists an effect by the following structures.

  In the fluid mixer 310, the torsion member 312 is formed in a shape in which both ends of the plate-like member are twisted in opposite directions by a predetermined angle around the flow path axis Z of the flow member 311. A plurality of tubes are disposed adjacent to each other in the tube. The mutually adjacent ends of the torsion members 312 adjacent to each other intersect each other. And on the outer peripheral surface of the flow member 311, a plane including the flow path axis Z of the flow member 311 and the uppermost stream side end of the torsion member 312 disposed on the uppermost stream side, the outer peripheral surface of the flow member 311, A first mark 313 is provided at a portion where the two intersect. A second mark 314 indicating the flow direction set for each fluid mixer 310 is provided on the outer peripheral surface of the flow member 311.

  According to such a configuration, the fluid can be mixed by allowing the fluid to pass through a plurality of torsion members 312 disposed adjacent to each other. Then, by visually recognizing the first mark 313 and the second mark 314, the direction around the flow axis Z of the upstream end portion of the upstreammost twist member 312 can be confirmed. Thereby, when installing the fluid mixer 310, the flow path axis Z of the flow member 311 at the end in the longitudinal direction on the upstream side of the torsion member 312 installed on the most upstream side without directly viewing the torsion member 312. The direction of the surroundings can be adjusted appropriately. Therefore, the work efficiency of the installation work can be improved with a simple configuration.

(Embodiment 4)
By connecting the fluid mixer described above in Embodiments 1 to 3 and the modification thereof to a cheese joint 404 (corresponding to a piping member), a junction joint 400 with a fluid mixer can be obtained. Hereinafter, this point will be described with reference to FIG.

  FIG. 8 is a cross-sectional view showing the confluence joint 400 with a fluid mixer according to the fourth embodiment from the same direction as 5-5 shown in FIG. 4.

  In the merging joint 400 with the fluid mixer, the cheese joint 404 is directly connected to the upstream side of the fluid mixer 210 according to the second embodiment.

  The cheese joint 404 includes a first opening 401 through which the first fluid flows, a second opening 402 through which the second fluid flows in, and a third opening 403 through which a mixed fluid of the first fluid and the second fluid flows out. Have. The third opening 403 has the same flow path axis direction as the first opening 401. The flow path axis direction of the first opening 401 and the third opening 403 is the same as the flow path axis Z direction of the flow member 211.

  The angle formed by the flow path axis Z1 of the second opening 402 and the plane including the flow path axis Z of the flow member 211 and the first mark 213 can be arbitrarily set. In the present embodiment, the angle formed by the flow path axis Z1 of the second opening 402 and the plane including the flow path axis Z of the flow member 211 and the first mark 213 is such that the flow path axis Z1 of the second opening 402 is It is set to an angle included in a plane including the flow path axis Z of the flow member 211 and the first mark 213. The angle between the flow path axis Z1 of the second opening 402 and the flow path axis Z of the flow member 211 and the plane including the first mark 213 includes the flow path axis Z1 of the second opening 402 and the flow member 211. In addition to the case where the angle formed by the flow path axis Z and the plane including the first mark 213 is 0 °, an angle in the vicinity thereof is included. The vicinity angle is equal to the mixing effect when the angle formed by the flow path axis Z1 of the second opening 402 and the plane including the flow path axis Z of the flow member 211 and the first mark 213 is 0 °. It is the angle of the range that can be obtained.

  In the fluid mixing using the junction joint 400 with a fluid mixer, one fluid flows into the first opening 401 and the other fluid flows into the second opening 402. One fluid and the other fluid respectively introduced from the first opening 401 and the second opening 402 are introduced into the fluid mixer 210 through the third opening 403. The fluid that has flowed into the fluid mixer 210 is stirred and mixed by the stirring member 212.

  In the present embodiment, the flow path axis Z <b> 1 of the second opening 402 is included in a plane including the flow path axis Z of the flow member 211 and the first mark 213. When the fluid mixer 210 is connected to the cheese joint 404 so that the flow path axis Z1 of the second opening 402 is included in a plane including the flow path axis Z of the flow member 211 and the first mark 213. And higher mixing effect. That is, in the confluence joint 400 with the fluid mixer, the fluid mixer 210 is connected to the cheese joint 404 in advance so that the fluid mixer 210 exhibits a higher mixing effect. Therefore, by using the confluence joint 400 with the fluid mixer, the fluid mixer 210 can be installed so as to obtain a higher mixing effect without worrying about the direction of the stirring member 212, and the installation work can be performed. It becomes easy.

  According to embodiment mentioned above, there exists an effect by the following structures.

  In the merging joint 400 with the fluid mixer, the cheese joint 404 is directly connected to the upstream side of the fluid mixer 210. The cheese joint 404 has a first opening 401 through which the first fluid flows, a second opening 402 through which the second fluid flows, and the same flow path axis direction as the first opening 401, and the first fluid and the second fluid And a third opening 403 through which a fluid mixture with the fluid flows out.

  According to such a configuration, when the junction joint 400 with a fluid mixer is installed on the upstream piping member of the junction joint 400 with a fluid mixer, the direction of the opening 212b around the flow path axis Z of the flow member 211 is changed. There is no need to adjust. Therefore, the work efficiency of the installation work can be improved with a simple configuration.

  Further, in the confluence joint 400 with the fluid mixer, the flow path axis Z 1 of the second opening 402 is included in a plane including the flow path axis Z of the flow member 211 and the first mark 213.

  According to such a configuration, the fluid mixer 210 is connected to the cheese joint 404 so that the fluid mixer 210 exhibits a higher mixing effect in advance. Therefore, by using the confluence joint 400 with the fluid mixer, the fluid mixer 210 can be installed so that a higher mixing effect can be obtained without worrying about the direction of the stirring member 212. It becomes easy.

(Modification of Embodiment 4)
In the confluence joint 400 with the fluid mixer according to the fourth embodiment, the cheese joint 404 is directly connected to the upstream side of the fluid mixer 210 according to the second embodiment, but the cheese joint 404 and the fluid mixer 210 are indirectly connected. You may connect to. Here, the cheese joint 404 and the fluid mixer 210 being indirectly connected means that the cheese joint 404 and the fluid mixer 210 are connected via another piping member.

  By indirectly connecting the cheese joint 404 and the fluid mixer 210, the mixing effect in the fluid mixing using the fluid mixer 210 can be finely adjusted. The mixing effect can be finely adjusted by adjusting the length of the piping member connected between the cheese joint 404 and the fluid mixer 210 and the pipe diameter of the piping member, for example.

  As another method for adjusting the mixing effect, as another piping member, for example, a piping member that rotatably connects the cheese joint 404 and the fluid mixer 210 may be used. Thereby, the direction of the stirring member 212 around the flow path axis Z of the flow member 211 can be easily adjusted so that an appropriate mixing effect can be obtained when the fluid mixer 210 is connected or after connection. Therefore, the work efficiency of the installation work is further improved and the maintainability is improved by a simple configuration.

  Furthermore, as another piping member, a piping member that detachably connects the cheese joint 404 and the fluid mixer 210 may be used. As a piping member that detachably connects the cheese joint 404 and the fluid mixer 210, for example, a union or a flange can be used. By using a piping member that removably connects the cheese joint 404 and the fluid mixer 210, the fluid mixer 210 can be easily attached and detached after the fluid mixer 210 is connected and installed. Therefore, for example, maintenance work such as cleaning of the opening 212b can be easily performed. Therefore, the maintainability of the fluid mixer 210 is further improved.

(Experimental example)
In the fluid mixer 210, an experiment by numerical fluid analysis was performed to show that the mixing effect changes depending on the direction of the opening 212b around the flow path axis Z of the flow member 211.

  Numerical fluid analysis was performed using STAR-CCM + (CD-adapco).

  The conditions of numerical fluid analysis are as follows. Referring to FIG. 9, in the piping system in which the cheese joint 500 is connected to the upstream side of the fluid mixer 210 and the straight pipe 600 is connected to the downstream side of the fluid mixer 210, the first fluid and the second fluid Numerical fluid analysis was performed when fluids were mixed. The first fluid and the second fluid are allowed to flow from the first opening 501 and the second opening 502 of the cheese joint 500, respectively. The first fluid was water, and the second fluid was water containing a certain amount of tracer material. The flow rates when the first fluid and the second fluid were allowed to flow from the first opening 501 and the second opening 502 were set to 1 m / sec, respectively.

  The mixing effect was evaluated at a point EP downstream of the straight pipe 600 from the downstream end of the fluid mixer 210 by a distance LP that is six times the diameter D of the fluid mixer 210. The mixing effect represents the variation of the tracer substance in the channel cross section as a coefficient of variation. The coefficient of variation is calculated from the standard deviation / average value of the concentration of the tracer substance.

  Table 1 shows changes in the mixing effect depending on the orientation of the opening 212b around the flow path axis Z of the flow member 211 in the fluid mixer 210.

  In Table 1, the direction of the opening 212 b around the flow path axis Z of the flow member 211 is represented by the connection angle of the fluid mixer 210 with respect to the cheese joint 500. The connection angle means an acute angle formed by the flow path axis of the second opening 502 and the surface including the flow path axis Z of the flow member 211 and the first mark 213. In Table 1, ◎ indicates a variation coefficient of 0.025 or less, ○ indicates a variation coefficient of 0.025 or more and less than 0.05, Δ indicates a variation coefficient of 0.05 or more and less than 0.075, and × indicates a variation coefficient of 0.075. It represents the above.

  As shown in Table 1, it can be seen that the mixing effect changes depending on the direction of the opening 212b around the flow path axis Z of the flow member 211.

  This experimental example was performed to show that the mixing effect changes according to the direction of the opening 212b around the flow path axis Z of the flow member 211, but the direction of the opening 212b from which an appropriate mixing effect can be obtained. It is also clear from the results of this experimental example that this is obtained by simulation.
