Further, it is necessary to form a groove in a case where a disc-shaped one is attached to the groove. On the other hand, in the case of caulking, the structure is simple, but there are many variations, and it is difficult to visually judge whether or not the caulking is performed properly or the caulking is performed with sufficient strength. You can also touch the filter with your hand to check it,
In such a case, automation is difficult.

記課題を解決した。According to the present invention, there is provided a fluid control valve having an opening at the tip of a cylinder as an inflow port, wherein a strainer made of a single disc is provided at the stepped portion of the opening. The above problem has been solved by providing a fluid control valve with a strainer in which the central portion of the strainer is deflected in the inflow direction by the caulking force of the caulking with the opening member.

に至りやすいのでたわみ方向を流入方向とした。That is, when caulking the outer circumference of a single disk, the caulking force is such that the strainer of the single disk flexes, so a sufficient caulking force can be secured. Further, since the strainer is deflected in the flow direction due to the caulking force, it is possible to determine whether or not the strainer is properly caulked by measuring the amount of the deflection. On the other hand, if the caulking force is too large, the strainer may be damaged or the opening may be damaged. On the other hand, if the caulking force is too small, the strainer may slightly move, fall off, or fall off. Therefore, when the caulking force is determined by the amount of deflection, the amount of deflection is preferably 0.5 to 5% of the outer diameter of the strainer (claim 2). In addition,
The bending direction may be opposite to the inflow direction, but in this case, the strainer pops out of the valve, so there is a risk of damage due to contact with the outside during work, transfer, etc. Further, depending on the inflow state, there is a risk of being biased in the inflow direction by dust, fluid resistance, etc., and may be deformed in the opposite direction. Further, since the deformation tends to lead to breakage, the bending direction is the inflow direction.

くなる。As shown in FIG. 1, particularly in FIG. 2, in the present invention, a step portion 15 is provided in the opening 43 of the cylindrical tip 34, and the step portion and the upper portion of the step portion are deformed by caulking. The outer peripheral portion 21 of the strainer 20 with the opening member 16
Is clamped and fixed in a crimped state. The strainer 20 is bent by the caulking force at the central portion 22 in the inflow direction with a deflection amount d. As shown in FIG. 3, the strainer 20 before mounting has, for example, a thickness t = 0.15 mm, an outer diameter D = 9 mm, a small hole diameter S of the small holes 23 = 0.3 mm, a small hole pitch P = 0.4 mm, and a small diameter. The outer diameter D'of the hole is 8 mm. On the other hand, as shown in FIG. 4, the step portion 15 of the tip 34 of the sheet holder 2 has a cylindrical tip outer diameter DT = 12 mm, a step depth h = 0.65 mm, and a step outer diameter DD = 9.1 mm. To be done. With such dimensions, as shown in FIG. 5, the strainer 20 is inserted into the step portion 15, and the rolling caulking member 24 having a diameter slightly larger than the outer diameter D of the step portion is used to inward the inner side of the tip end portion 34a inward. The strainer 20 is deformed while being biased to the outer periphery 21 of the strainer 20 and is crimped while being compressed inward.
Here, by forming the stepped portion 15 into a mortar-like taper, it is easy to bend downward, and deformation due to caulking can be reliably performed. On the contrary, a mountain-shaped taper makes it easy to bend upward.

ればよいことはいうまでもない。As a result, the member at the tip end portion is deformed to the outer periphery of the strainer 20, and the strainer is clamped between the opening member 16 and the step portion 15, and the caulking state is established. The strainer 20 is elastically deformed in the inflow direction due to the inward compressive force during crimping. The strainer having such a bend is securely fixed by the elastic force, and does not fall off during assembly, transfer, after mounting, or the like. If the amount of deflection d is small, the elastic force is small, and if it is large, the amount of plastic deformation is large, and it is easily damaged. Therefore, the amount of deflection d is 0.05 to 0.3.
5 mm (0.55% to 3.9% of the strainer outer diameter). The strainer 20 is made of stainless steel (SU
S304), the material of the sheet holder (tip 34) 2 is preferably an aluminum material (ADC), but the material can be appropriately selected from resin or other metal materials. Needless to say, when the inflow direction is opposite, it may be bent upward as seen in the figure as shown by the dotted line in FIG.

The control device 70 includes a device 66, processing of data from the laser length measuring device, a command to the servo motor amplifiers 67 and 68, a control device 70 for controlling a command to the sorting device 66, and the like. These constituent devices are generally used, and detailed description thereof will be omitted. In such an apparatus, the strainer component (the above-mentioned sheet holder) 60 is attached to the jig with the cylindrical tip end facing upward, and is mounted on the inspection table 62 so that the center of the strainer 20 coincides with the measurement center.
The laser measuring device 65 moves according to the mounting signal, and measures the length from the outer peripheral edge of the strainer to the outer peripheral edge of the strainer on the opposite side through the center. The deflection amount d is calculated by correcting the small hole portion and the outer peripheral portion and the central portion among the measured values. If the deflection amount d is out of the specified value, it is determined to be unacceptable, and the sorting device 66 sends it to the unacceptable line. If it is within the specified value, it is determined as a pass and is sent to the pass line by the sorting device 66. In addition, if the strainer is not attached, it will be sent to the reject line as being out of regulation. This makes it possible to automate the inspection of the presence or absence of strainers and the mounting state. Since the height of the sheet holder has relatively little variation, there is also an advantage that the inspection device can be easily simplified in the measurement.

It goes without saying that it can be applied. Further, when inspecting the strainer parts, the measurement was performed with the strainer attached to the seat holder, but other parts such as the opening side seat 4, the ball 5, the spacer 7 and the body side seat 6 were assembled, or the solenoid valve was installed. Needless to say, it is possible to measure as a strainer component even when assembled as. Further, in the embodiment, the strainer is swaged all around, but it may be partially swaged.

でき、自動化も可能となった。According to the present invention, the outer peripheral surface of the strainer having a single disc is caulked by the opening member, and the central portion of the strainer is deflected by the caulking force toward the inflow direction. Even if the plate strainer is caulked, it can be mounted with sufficient strength and reliable mounting. Also, there is no fear of falling off due to temperature change due to the difference in thermal expansion coefficient between the strainer and the cylindrical tip. In addition, since it is possible to measure the flexure condition visually or by measuring the flexure amount, it becomes easy to confirm whether or not the caulking is the intended condition.
Furthermore, since no locking portion or groove is required, the space is saved and the processing is simplified. The amount of deflection can be quantified as 0.5 to 5% of the outer diameter of the strainer, and the quality is stable. Also, by applying it to a solenoid valve, malfunctions can be prevented and automation becomes possible.
