Detailed description of the invention
Referring to accompanying drawing, embodiments of the present invention are described.Embodiment is that fluid control devices is that motor-driven valve is also by the example of this motor-driven valve soldering on the pipe arrangement of cooling cycle system (fluid circulating system).Fig. 1 represents the motor-driven valve of embodiments of the present invention to carry out well the state (Fig. 1 (A)) of brazing operation and do not carried out well the figure of the state (Fig. 1 (B)) of brazing operation.Fig. 2 is the stereogram of the motor-driven valve of embodiment, and Fig. 2 (A) represents to install the state before indicator 3, and Fig. 2 (B) represents to install the state after indicator 3.Fig. 3 is the figure that represents the detailed structure of the major part of the indicator 3 of embodiment, Fig. 3 (A) is the side view of the installment state of indicator 3, Fig. 3 (B) is the side view of indicator 3, Fig. 3 (C) is the upward view of indicator 3, and Fig. 3 (D) is the longitudinal section of indicator 3.
Motor-driven valve 100 has main part 1 and two joints 2.In the periphery of main part 1, not shown stator unit is installed, accommodates the rotor that forms stepper motor together with stator unit in the inside of main part 1.And, be equipped with in the inside of main part 1 by the rotation of rotor and make valve body with respect to the directly O-ring seals etc. of moving resinous thread mechanism and seal valve chamber etc. of valve seat.And when soldering pipe arrangement 10, Ruo Gaore is delivered to the inside of this main part 1 on joint 2, can cause deteriorated, the change in physical of distortion, the magnetic characteristic of the various mentioned components of main part 1 inside etc., therefore detect whether because this situation has occurred in soldering.
Hot impact when detecting above-mentioned soldering is separately installed with indicator 3 on joint 2.As shown in Figure 3, indicator 3 is parts of drum, is made up of the synthetic resin as thermoplastic component.As shown in Figure 2, indicator 3 is arranged on respectively main part 1 side of joint 2 root to cover the all-round mode of joint 2 divides A,, the end 21 of joint 2 be with respect to pipe arrangement 10 by the bonding part of soldering, indicator 3 the most approaching end 21 from joint 2 away from main part 1 install.Further, as shown in Fig. 2 (B), a side joint 2 is bent processing after indicator 3 has been installed.
Fig. 1 represents the appearance of a side joint 2 with the brazing operation of pipe arrangement 10, and brazing operation carries out as follows.Clean the composition surface of joint 2 and pipe arrangement 10, coating solder flux is also assembled in joint 2 on pipe arrangement 10.Wet by the use part of the main body covered portions 1 such as loose thread and indicator 3, thus cooling this main part 1 and indicator 3 utilize burner 20 to heat pipe arrangement 10 and the bonding part of joint 2 on one side on one side.Further, burner 20 applies the heat that exceedes 3000 DEG C carrying out acetylene gas welding occasion.And, melt solder, cooling afterwash etc. in this bonding part.Further, as the method for cools body portion 1 and indicator 3, can be also that main part 1 and indicator 3 are dipped into the method in the water of tank etc.
Completing after this brazing operation, by the shape of Visual Confirmation indicator 3, if on indicator 3, be not out of shape, go bad etc., soldering is good.If as Fig. 1 (B), in the case of not carrying out smoothly the Local cooling of main part 1 and indicator 3 because of certain, produce and conduct heat from bonding part to joint 2, if this heat passes to a part for indicator 3, can on this indicator 3, produce distortion, go bad etc.And the possibility of inside that this heat is delivered to main part 1 is also high.Therefore, if there is distortion, rotten etc. on indicator 3, brazing operation is bad, pulls down motor-driven valve 100, carries out identical operation with other motor-driven valve 100.
In addition,, in the situation that having completed brazing operation well, the indicator 3 of motor-driven valve 10 both can former state be arranged on joint 2, also can remove.In the situation that former state has been installed indicator 3, this motor-driven valve 10 also can confirm to have carried out well the situation of brazing operation afterwards.
Fig. 4～Fig. 6 is the figure that represents other examples of indicator 3, in each figure, figure (A) is the side view of the installment state of indicator 3, figure (B) is the side view of indicator 3, figure (C) is the upward view of indicator 3, and figure (D) is the longitudinal section of indicator 3.These indicators 3 are also made up of the synthetic resin as thermoplastic component.
The indicator 3 of Fig. 4 is the members that are formed with multiple translots 31 at a side's of the main body of general cylindrical shape shape edge along radial direction.This indicator 3 makes a method, edge that does not form translot 31 towards main part 1 side, and is arranged on joint 2.The indicator 3 of Fig. 5 is the members that are longitudinally formed with multiple pods 32 in the periphery of the main body of general cylindrical shape shape.If form groove as the translot 31 of Fig. 4 or the pod 32 of Fig. 5, in the situation that having melted a part because of heat, indicator 3 easily identifies this state.The indicator 3 of Fig. 6 is annular members of circular ring type.According to the indicator 3 of this Fig. 6, even also can install after bending machining has been implemented in butt joint 2.
Fig. 7 is the figure that represents another example of indicator 3.The indicator 3 of Fig. 7 (A)～Fig. 7 (C) is the shapes by the clip shape forming as the synthetic resin of thermoplastic component.Further, Fig. 7 (A) represents the state of the indicator 3 that Fig. 7 (B) has been installed, and as the shape of clip, can be also the such shape of Fig. 7 (C).Even if these indicators 3 also can be installed after bending machining has been implemented in butt joint 2.And, can utilize the elasticity of the resin of the circular arc portion of the shape of clip shape to fix indicator 3.The indicator 3 of Fig. 7 (D) is by the latticed shape forming as the synthetic resin of thermoplastic component, also can install after bending machining has been implemented in butt joint 2 by stretching.And, can utilize the elasticity of latticed shape and resin to fix indicator 3.
Fig. 8 is the figure that represents other examples of fluid control devices, and Fig. 8 (A) is the example of four-port conversion value, and Fig. 8 (B) is the example of magnetic valve.The four-port conversion value 200 of Fig. 8 (A) has main part 1 and four joints 2.Accommodate not shown guiding valve, piston, valve seat, O-ring seals etc. in the inside of main part 1.And, on each joint 2, be separately installed with indicator 3.The magnetic valve 300 of Fig. 8 (B) has main part 1 and two joints 2.Accommodate not shown plunger, plunger tube, attractor, valve seat, O-ring seals ring etc. in the inside of main part 1.And, on each joint 2, be separately installed with indicator 3.In addition,, as the indicator 3 of Fig. 8 (A) and the indicator 3 of Fig. 8 (B), can use each indicator 3 of Fig. 1 to Fig. 7.
The indicator 3 of above embodiment, as material, use be thermoplastic synthetic resin, but about the detailed content of material, also can adopt following scheme.When soldering, because external temperature is higher than internal temperature, therefore also the resin material identical material using with the internal part of main part 1 can be used to indicate to device 3.In addition, in order to improve safety coefficient, the low material of material that can also use fusing point to use than internal part.For example, in the situation that internal part uses PPS, PBT or PET material can be used to indicate to device 3.
