Description
【０００１】[0001]
本考案は、スイング式逆止弁に関する。 The present invention relates to a swing check valve.
【０００２】[0002]
図４に示す従来のスイング式逆止弁の弁体２０は、取扱液が特殊でない限り鋳 鉄製であり、弁体１に弁棒６により回動自在に支持された弁体２０の弁座面には 、弁座２に当接するゴムシート２１をゴムシート押え板２２及びボルト２３によ り取付けているのが一般的である。 The valve body 20 of the conventional swing check valve shown in FIG. 4 is made of cast iron unless the handled liquid is special, and the valve seat surface of the valve body 20 rotatably supported by the valve body 1 by the valve rod 6. In general, a rubber sheet 21 that contacts the valve seat 2 is attached by a rubber sheet pressing plate 22 and bolts 23.
【０００３】[0003]
したがって、鋳鉄製の弁体２０は、鋳造に手間がかかって面倒である。また、 弁閉時に逆流によりゴムシート２１がめくれ折れ曲って弁座２との間に噛み込ま れ損傷することがあり、更に、水流で弁体２０が開口して回動したとき、弁体２ ０の背面部の突部２０ａが弁箱１に係止されて開口角度θを形成する際の衝突音 が大きいという欠点がある。 Therefore, the cast iron valve body 20 is troublesome because it takes time and effort for casting. In addition, when the valve is closed, the rubber sheet 21 may be bent and bent due to backflow and may be caught between the valve seat 2 and damaged. There is a disadvantage that the collision noise when the protrusion 20a of the rear portion of 0 is locked to the valve box 1 to form the opening angle θ is large.
【０００４】 本考案は、ゴムシートのめくれ折り曲がりによる損傷を防止し、弁体開口時の 衝突音を軽減したスイング式逆止弁を提供することを目的としている。An object of the present invention is to provide a swing-type check valve that prevents damage due to the curling and bending of a rubber sheet and reduces collision noise when the valve body is opened.
【０００５】[0005]
本考案によれば、鋼板プレス成形弁体に弁座板をゴムモールド成形し、該弁体 の背面部に突起部をゴムモールド成形している。 According to the present invention, the valve seat plate is rubber-molded on the steel plate press-molded valve body, and the protrusion is rubber-molded on the back surface of the valve body.
【０００６】[0006]
上記のように構成されたスイング式逆止弁においては、弁座板はゴムモールド により弁体と一体に形成されているので、めくれ折れ曲って弁座との間に噛み込 まれて損傷するのが防止される。 In the swing-type check valve configured as described above, the valve seat plate is formed integrally with the valve body by the rubber mold, so it is bent over and bent and caught between the valve seat and damage. Is prevented.
【０００７】 また、背面部の突部もゴムモールドで弁体と一体に形成されているので、弁箱 との衝突音が極めて軽減される。Further, since the protruding portion on the back surface is also integrally formed with the valve body by the rubber molding, the noise of collision with the valve box is extremely reduced.
【０００８】 また、弁体は鋼板プレスで形成されるので、加工、組立てが容易であり、更に 、表面が平面的かつ平滑なので、圧力損失水頭が小さい。Further, since the valve element is formed by a steel plate press, it is easy to process and assemble, and the surface is flat and smooth, so the pressure loss head is small.
【０００９】[0009]
以下図面を参照して本考案の実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.
【００１０】 図１において、弁箱１内には、弁座２が形成され、流入口３と弁座２との間は 、バイパス弁取付部４に連通されている。その弁座２に着座する全体を符号１０ で示す弁体は、弁箱１に固設された弁棒６により流出口５側に回動自在に設けら れている。In FIG. 1, a valve seat 2 is formed in the valve box 1, and a space between the inflow port 3 and the valve seat 2 is communicated with a bypass valve mounting portion 4. The valve body, which is entirely seated on the valve seat 2 and is denoted by reference numeral 10, is rotatably provided on the outflow port 5 side by a valve rod 6 fixed to the valve box 1.
【００１１】 図２及び図３をも参照し、弁体１０の本体１１は鋼板製で作られ、円形部１２ と弁棒６を巻回するヒンジ部１５とがプレス成形されている。そして円形部１２ の中心には彎曲部１２ａが形成され、その円形部１２の弁座２側には、弁座板１ ４が彎曲部１２ａを除いてゴムモールドで一体に取付けられている。そして、弁 座板１４に対向する側の彎曲部１２ａの所には、突起部すなわちストッパ１３が ゴムモールドにより一体に形成されている。Referring also to FIGS. 2 and 3, the main body 11 of the valve body 10 is made of a steel plate, and the circular portion 12 and the hinge portion 15 around which the valve rod 6 is wound are press-molded. A curved portion 12a is formed at the center of the circular portion 12, and a valve seat plate 14 is integrally attached to the circular seat 12 on the valve seat 2 side by a rubber mold except for the curved portion 12a. At the curved portion 12a on the side facing the valve seat plate 14, a protrusion portion, that is, a stopper 13 is integrally formed by rubber molding.
【００１２】 したがって、閉弁時に逆流により一体に取付けられた弁座板１４がめくれ折れ 曲って弁座２との間に噛み込まれることが防止される。また、水流で弁体１０が 回動して開口し、図１の鎖線で示すようにストッパ１３が弁箱１に係止されて適 切な開口角度θを形成する際、ストッパ１３と弁箱１との衝突音が極めて軽減さ れる。Therefore, when the valve is closed, it is possible to prevent the valve seat plate 14 integrally attached by backflow from being bent and bent and being caught in the valve seat 2. Further, when the valve body 10 is rotated and opened by the water flow and the stopper 13 is locked to the valve box 1 to form an appropriate opening angle θ as shown by the chain line in FIG. 1, the stopper 13 and the valve box 1 are closed. Collision noise with is greatly reduced.
【００１３】[0013]
【考案の効果】 本考案は、以上説明したように構成されているので、以下に記載されるような 効果を奏する。EFFECTS OF THE INVENTION Since the present invention is configured as described above, it has the following effects.
【００１４】 弁座板をゴムモールドにより弁体を一体に成形し、弁座板のめくれ折り曲がり による損傷を防止することができる。It is possible to prevent the valve seat plate from being integrally formed with the valve seat plate by using a rubber mold to prevent the valve seat plate from being turned up and down.
【００１５】 ストッパをゴムモールドで成形し、弁体開口時の衝突音を極めて軽減すること ができる。By forming the stopper with a rubber mold, it is possible to significantly reduce the collision noise when the valve body is opened.
【００１６】 弁体本体を鋼板プレス成形し、加工、組立を容易にすると共に、圧力損失水頭 を低減することができる。The valve body can be press-formed with a steel plate to facilitate processing and assembly and reduce the pressure loss head.
