本発明は傘形弁体を有するバルブ部材の製造方
法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a valve member having an umbrella-shaped valve body.
傘形弁体を有するバルブにおいて、傘形弁体は

方へ伸びる誘導部を有しており、この先端を弁座
部材の取付け孔に挿入して、引張ることによつ
て、ストツパ部が弁座部材の取付け孔から完全に
抜けきつた時点で取付けが完了し、その後不用と
なつた誘導部をカツタ等を用いて切断除去してい

ないためである。 In a valve having an umbrella-shaped valve body, the umbrella-shaped valve body is inserted into the mounting hole of the valve seat member through the shaft portion extending downward from the center portion of the inner surface of the umbrella-shaped valve body, and the cap portion of the umbrella-shaped valve body and the stopper at the lower end of the shaft. The valve seat member is attached by holding the valve seat member from above and below between the parts. In this case, the umbrella-shaped valve body before installation has a guiding part extending downward from the lower end of the stopper of the shaft, and by inserting this tip into the mounting hole of the valve seat member and pulling it, the stopper can be removed. The installation is completed when the guide part is completely removed from the mounting hole of the valve seat member, and the unnecessary guide part is then cut and removed using a cutter or the like. The reason why an umbrella-shaped valve body with a guiding part is used is that the valve body is generally made of an elastic material with low hardness, so the stopper part of the umbrella-shaped valve body without a guiding part is placed on the valve seat. This is because even if force is applied from the upper surface of the umbrella part facing the mounting hole of the member, the shaft part will buckle and the stopper part will not enter the mounting hole of the valve seat member.
本発明は上記に鑑みてなされたもので、ストツ
パ部と誘導部との間に切欠き部を設けることによ
つて、取付け孔に傘形弁体を取付けると同時に、
カツタを用いることなく取付け時に誘導部先端か
ら引張る力によつて傘形弁体の誘導部を切断除去
するようにしたものである。 The present invention has been made in view of the above, and by providing a notch between the stopper part and the guiding part, the umbrella-shaped valve body can be mounted in the mounting hole at the same time.
The guide portion of the umbrella-shaped valve body is cut and removed by a pulling force from the tip of the guide portion during installation without using a cutter.

る。 The present invention will be explained below based on the drawings. In FIG. 1, an umbrella-shaped valve body 1 used in the present invention consists of an umbrella portion 2, a shaft portion 3, and a guide portion 4. The umbrella part 2 has an inverted dish shape, and has a stepped part 5 in the center of the inner surface for regulating the mounting position of the umbrella part 2 in the axial direction. The height of the stepped portion 5 is lower than the outer peripheral portion of the umbrella portion 2, and the diameter thereof is larger than that of the shaft portion 3. Shaft part 3
extends downward from the lower end of the stepped portion 5 of the umbrella portion 2, and has a stopper portion 6 that is thicker than the diameter of the shaft portion 3 at the lower portion. The guide portion 4 extends downward from the stopper portion 6 of the shaft portion 3, and gradually becomes thinner as it moves away from the base portion. The guide portion 4 has a notch portion 7 having a smaller diameter at its base. Note that the notch portion 7 may be simply a notch. Valve seat member 8 shown in FIG.
is disk-shaped and has a mounting hole 9 in the center and one or more holes 10 around the mounting hole 9. The diameter of the mounting hole 9 is approximately equal to the diameter of the shaft portion 3 of the umbrella-shaped valve body 1, and the opening 10 is sized to fit inside the outer diameter of the umbrella-shaped valve body 1. The distance between the step portion 5 and the stopper portion 6 of the umbrella-shaped valve body 1 is approximately equal to the thickness of the valve seat member 8.

に示すバルブ１４となる。 The valve member 11 is composed of the above-mentioned parts and is manufactured in the following order. By inserting the guiding part 4 of the umbrella-shaped valve body 1 into the mounting hole 9 of the valve seat member 8 and pulling the tip of the guiding part 4, the stopper part 6 is completely pulled out from the mounting hole 9 of the valve seat member 8. The installation is complete when the Then, when pulled with even stronger force, the notch part 7 has a smaller diameter than the shaft part 3 and the guide part 4 and is constricted, so it is cut from that part and the guide part 4 is separated. Then, the valve seat member 8 is held between the step portion 5 and the stopper portion 6 of the umbrella-shaped valve body 1, and the valve member 11 is completed. The valve member 11 becomes a valve 14 shown in FIG. 3 by airtightly fitting a casing 13 having, for example, a vent 12 above and below the valve member 11, as necessary.

弁座部材にも容易に取付けが可能である。 The present invention is comprised of the above components and manufacturing process, and since there is no step of cutting and removing the guide portion of the umbrella-shaped valve body, the manufacturing process can be reduced, and therefore manufacturing costs can be reduced. . Furthermore, even if the area where the guiding part protrudes is narrow, it can be removed without leaving the guiding part, so it can be easily attached to a valve seat member with a complicated shape.
