A guide member 28 to be inserted into the guide groove 18 is attached, and a shaft seal member 19 is attached to the upper through hole of the frame storage portion 22. Further, a pair of fixing projections 30, 30 for fixing the holding plate 25 and the sealing material 26 are provided on both side surfaces of the valve body 21.

シール材２６は、全閉状態で弁箱内周面下半部に設けられた下向き円弧状の下部弁座１２ａに当接する下部シール部３１と、前記開口部１３の弁体収容部１４側を向いた面にそれぞれ設けられた上向き円弧状の上部弁座１３ａに当接する上部シール部３２と、下部シール部３１と上部シール部３２との内周側に一体成形された円盤状のシール材本体３３とで形成されており、弁本体２１の側面形状に対応した形状を有するシール材本体３３には、前記固定用突部３０を挿通させる一対の挿通孔３４，３４が形成されている。   The sealing material 26 includes a lower seal portion 31 that contacts the downward arcuate lower valve seat 12a provided in the lower half of the inner peripheral surface of the valve box in the fully closed state, and the valve body housing portion 14 side of the opening 13.

A pair of insertion holes 35 and 35 through which 30 is inserted are formed.

弁本体２１へのシール材２６の取り付けは、挿通孔３４に固定用突部３０を挿通させてシール材２６のシール材本体３３を弁本体２１の側面に当接させるとともに、挿通孔３５に固定用突部３０を挿通させて保持板２５をシール材本体３３の外面に当接させた状態で、保持板２５の外面に突出した固定用突部３０の先端円筒部３０ａをワッシャ３６を介して押し拡げる。これにより、図４に示すように、固定用突部３０の先端外周に形成された押し拡げ部３０ｂがワッシャ３６を介して保持板２５を弁本体２１の側面に固定した状態となり、弁本体２１の側面と保持板２５との間にシール材本体３３を挟持し、弁本体２１の周囲の所定の位置に下部シール部３１と上部シール部３２とが突出した状態となる。   The sealing member 26 is attached to the valve body 21 by inserting the fixing protrusion 30 into the insertion hole 34 to bring the sealing member body 33 of the sealing member 26 into contact with the side surface of the valve body 21 and fixing to the insertion hole 35. In the state where the projection 30 is inserted and the holding plate 25 is brought into contact with the outer surface of the sealing material body 33, the distal end cylindrical portion 30 a of the fixing projection 30 protruding from the outer surface of the holding plate 25 is inserted through the washer 36. Expand. As a result, as shown in FIG. 4, the expanded portion 30 b formed on the outer periphery of the distal end of the fixing projection 30 is in a state where the holding plate 25 is fixed to the side surface of the valve body 21 via the washer 36. The sealing material main body 33 is sandwiched between the side surface of the main body and the holding plate 25, and the lower seal portion 31 and the upper seal portion 32 protrude at predetermined positions around the valve main body 21.

このように、弁本体２１の側面に突設した固定用突部３０を、シール材２６の挿通孔３４及び保持板２５の挿通孔３５に挿入し、保持板２５の外面に突出した固定用突部３０の先端部をかしめて保持板２５の外面に向けて押し拡げるように変形させ、押し拡げ部３０ｂがハトメ状に保持板２５の外面に沿う状態とすることにより、弁本体２１の両側面にシール材２６をそれぞれ取り付けることができ、弁本体２１に従来のようなボルト挿通孔を貫通形成する必要がないので、全閉時のシール性を確保することができ、確実なシール状態を得ることができる。   As described above, the fixing protrusion 30 protruding from the side surface of the valve body 21 is inserted into the insertion hole 34 of the sealing material 26 and the insertion hole 35 of the holding plate 25, and the fixing protrusion protruding from the outer surface of the holding plate 25. The both ends of the valve body 21 are formed by crimping the tip of the portion 30 so as to be expanded toward the outer surface of the holding plate 25 so that the expanded portion 30b fits along the outer surface of the holding plate 25 in an eyelet shape. The seal member 26 can be attached to the valve body 21, and it is not necessary to penetrate the valve body 21 with a bolt insertion hole as in the prior art. Therefore, the sealing property when fully closed can be secured, and a reliable sealing state is obtained. be able to.

図８乃至図１０は、本発明の第１形態例を示している。なお、以下の説明において、前記参考例に示したソフトシール仕切弁の構成要素と同一の構成要素には同一の符号を付して詳細な説明は省略する。 8 to 10 show a first embodiment of the present invention. In the following description, the same components as those of the soft seal gate valve shown in the reference example are denoted by the same reference numerals, and detailed description thereof is omitted.

本形態例は、前記弁本体２１の両側面に、有底の装着穴４１を２箇所ずつそれぞれ形成するとともに、各装着穴４１に、前記シール材２６の挿通孔３４及び保持板２５の挿通孔３５を通って保持板２５の外面に先端部４２ａが突出する固定用突出部材４２を装着した例を示している。装着穴４１の位置は、弁本体２１の厚さを考慮して一側面の装着穴４１と他側面の装着穴４１とが重ならないように配置し、固定用突出部材４２を装着するのに十分な深さを確保するとともに、弁本体２１のいずれの側面においても、図８に示すように、２箇所の装着穴４１が右上と左下とになるようにして両側面の装着穴４１が、表裏各側面を正面から見た状態で同じ位置になるようにしている。 In this embodiment, two bottomed mounting holes 41 are formed on both side surfaces of the valve body 21, and the insertion holes 34 of the sealing material 26 and the insertion holes of the holding plate 25 are inserted into the mounting holes 41. An example is shown in which a fixing protruding member 42 with a tip end 42 a protruding from the outer surface of the holding plate 25 through 35 is mounted. The mounting hole 41 is positioned so that the mounting hole 41 on one side does not overlap the mounting hole 41 on the other side in consideration of the thickness of the valve body 21, and is sufficient to mount the fixing protruding member 42. As shown in FIG. 8, on both sides of the valve body 21, the mounting holes 41 on both sides are provided on the front and back sides so that the two mounting holes 41 are located on the upper right side and the lower left side. Each side is in the same position as seen from the front.

これにより、弁本体２１が中心線（弁棒収納筒部２４の軸線）を対称軸として回転対称形状となり、シール材２６の挿通孔３４及び保持板２５の挿通孔３５を、装着穴４１と同じように右上と左下とに形成することができ、シール材２６や保持板２５に勝手違いが発生することを防止している。   As a result, the valve body 21 has a rotationally symmetric shape with the center line (the axis of the valve stem storage cylinder portion 24) as the symmetry axis, and the insertion hole 34 of the sealing material 26 and the insertion hole 35 of the holding plate 25 are the same as the mounting hole 41. Thus, it can be formed in the upper right and the lower left, and it is possible to prevent the seal material 26 and the holding plate 25 from being mistaken.

装着穴４１への固定用突出部材４２の装着は、例えば、弁本体２１を鋳造にて形成する場合は、鋳型の所定位置に固定用突出部材４２をそれぞれ固定してから溶湯を注入して弁本体２１を鋳造することにより、固定用突出部材４２を所定位置に装着した状態の弁本体２１を形成することができる。また、溶接やねじ込みによって固定用突出部材４２を装着穴４１に装着することも可能である。   For example, when the valve main body 21 is formed by casting, the fixing projecting member 42 is attached to the mounting hole 41 by injecting molten metal after fixing the fixing projecting member 42 to a predetermined position of the mold. By casting the main body 21, it is possible to form the valve main body 21 with the fixing projecting member 42 mounted in a predetermined position. Further, the fixing protruding member 42 can be mounted in the mounting hole 41 by welding or screwing.

弁本体２１へのシール材２６の取り付けは、前記第１形態例と同様に、シール材２６の挿通孔３４及び保持板２５の挿通孔３５に固定用突出部材４２を挿通させ、保持板２５の外面に突出した固定用突出部材４２の先端部４２ａをワッシャ３６を介して押し拡げることによって行うことができる。   The sealing member 26 is attached to the valve body 21 in the same manner as in the first embodiment by inserting the fixing protruding member 42 through the insertion hole 34 of the sealing material 26 and the insertion hole 35 of the holding plate 25. This can be done by expanding the tip end portion 42a of the fixing protruding member 42 protruding to the outer surface through the washer 36.

このように、弁本体２１と固定用突出部材４２とを別部材で形成することにより、弁本体２１と固定用突出部材４２とに、それぞれ最適な材料を使用することができる。例えば、弁本体２１を従来と同じ鋳物で形成し、固定用突出部材４２をステンレス鋼で形成することが可能となる。   Thus, by forming the valve main body 21 and the fixing protruding member 42 as separate members, it is possible to use optimum materials for the valve main body 21 and the fixing protruding member 42, respectively. For example, the valve main body 21 can be formed of the same casting as the conventional one, and the fixing protruding member 42 can be formed of stainless steel.

また、固定用突出部材４２の先端部の形状は、該先端部を保持板２５の外面に向けて変形させて保持板２５を弁本体２１に固定することができれば、固定用突出部材４２の太さや材質に応じた形状を適宜に採用することができる。例えば、固定用突出部材４２として、図１０（ａ）に示す先端円筒部４３ａの４箇所に等間隔でスリット４３ｂを形成したもの、図１０（ｂ）に示す先端円筒部４４ａの６箇所に等間隔でスリット４４ｂを形成したもの、図１０（ｃ）に示す先端を薄肉の円筒部４５としたもの、あるいは、図１０（ｄ）に示すように、通常のリベットと同様に、先端４６まで中実の円柱状としたものなどを選択することが可能である。なお、これらの先端部の形状は、前記参考例で示した固定用突部３０の先端部についても同様である。 Further, the shape of the distal end portion of the fixing projecting member 42 is such that if the retaining plate 25 can be fixed to the valve body 21 by deforming the distal end portion toward the outer surface of the retaining plate 25, the fixing projecting member 42 is thicker. A shape according to the sheath material can be adopted as appropriate. For example, as the fixing projecting member 42, slits 43b are formed at equal intervals in four positions of the tip cylindrical portion 43a shown in FIG. 10A, and the tip cylindrical portion 44a shown in FIG. A slit 44b formed at intervals, a thin cylindrical portion 45 as shown in FIG. 10C, or a normal rivet as shown in FIG. It is possible to select an actual cylindrical shape. The shapes of these tip portions are the same for the tip portions of the fixing projections 30 shown in the reference example.

図１１乃至図１３は、本発明の第２形態例を示している。本形態例は、前記弁本体２１の両側面に、入口部に比べて底部を大径に形成した有底の拡底穴５１を、前記第２形態例に示した装着穴４１と同様の位置に２箇所ずつそれぞれ形成し、弁本体２１の側面に重ねて当接させたシール材２６及び保持板３５の外側から保持板２５の挿通孔３５及びシール材２６の挿通孔３４を通して前記拡底穴５１に固定用挿入部材５２を挿入し、固定用挿入部材５２の先端部５２ａを拡底穴５１の底部で拡径させることによって固定用挿入部材５２を拡底穴５１に固着し、固定用挿入部材５２の基端部に設けられている大径頭部５２ｂによって弁本体２１の側面との間に前記シール材２６を挟持した状態で保持板２５を弁本体２１の側面に固定するように形成している。
11 to 13 show a second embodiment of the present invention. In this embodiment, a bottomed widened hole 51 having a bottom that is larger in diameter than the inlet is formed on both side surfaces of the valve body 21 at the same position as the mounting hole 41 shown in the second embodiment. The bottomed hole 51 is formed in two places, from the outside of the sealing material 26 and the holding plate 35 which are formed in contact with each other on the side surface of the valve body 21 through the insertion hole 35 of the holding plate 25 and the insertion hole 34 of the sealing material 26. The fixing insertion member 52 is inserted, and the distal end portion 52a of the fixing insertion member 52 is expanded at the bottom of the bottom expansion hole 51 to fix the fixing insertion member 52 to the bottom expansion hole 51. The holding plate 25 is fixed to the side surface of the valve body 21 in a state where the sealing material 26 is sandwiched between the large-diameter head portion 52b provided at the end portion and the side surface of the valve body 21.

拡底穴５１の底部における固定用挿入部材５２の先端部５２ａの拡径は、固定用挿入部材５２の材質や太さなどに応じて適宜な方法で行うことができるが、例えば、図１１に示すように、弁本体２１の鋳造時に拡底穴５１の底部にあらかじめ拡径用の円錐部材５３を鋳込んだ状態で形成するとともに、固定用挿入部材５２の先端部５２ａを円筒状に形成し、拡底穴５１に挿入した固定用挿入部材５２の先端部５２ａを円錐部材５３に押し付けることにより、円錐部材５３によって先端部５２ａを拡底穴５１の底部で拡径させることができる。   The diameter of the tip 52a of the fixing insertion member 52 at the bottom of the bottom expansion hole 51 can be increased by an appropriate method depending on the material and thickness of the fixing insertion member 52. For example, as shown in FIG. As described above, when the valve body 21 is cast, the conical member 53 for expanding the diameter is formed in advance in the bottom of the expanded hole 51, and the distal end portion 52a of the fixing insertion member 52 is formed in a cylindrical shape. By pressing the distal end portion 52 a of the fixing insertion member 52 inserted into the hole 51 against the conical member 53, the diameter of the distal end portion 52 a can be increased at the bottom portion of the widened hole 51 by the conical member 53.

このように、拡底穴５１の底部に円錐部材５３を配置した場合の固定用挿入部材５２の先端部の形状は、前記第１，第２形態例における固定用突部３０の先端部形状や固定用突出部材４２の先端部形状と同様に、固定用挿入部材５２の太さや材質に応じた形状を適宜に採用することができる。すなわち、図１２（ａ）に示すように先端円筒部５４ａの６箇所に等間隔でスリット５４ｂを形成したもの、図１２（ｂ）に示すように先端円筒部５５ａの４箇所に等間隔でスリット５５ｂを形成したもの、図１２（ｃ）に示すように先端を薄肉の円筒部５６としたもの、図１２（ｄ）に示すように先端５７まで中実の円柱状としたものなどを選択することが可能である。また、拡径用の円錐部材５３を設けることができない場合は、固定用挿入部材５２としてブラインドリベットを使用することができる。   As described above, the shape of the distal end portion of the fixing insertion member 52 when the conical member 53 is disposed at the bottom portion of the widened hole 51 is the shape of the distal end portion of the fixing projection 30 or the fixed shape in the first and second embodiments. Similar to the shape of the distal end portion of the projecting member 42, a shape corresponding to the thickness and material of the fixing insertion member 52 can be appropriately employed. That is, as shown in FIG. 12 (a), slits 54b are formed at six locations on the tip cylindrical portion 54a at equal intervals, and as shown in FIG. 12 (b), slits are formed at four locations on the tip cylindrical portion 55a at regular intervals. One having 55b formed, one having a thin cylindrical portion 56 as shown in FIG. 12 (c), or one having a solid cylindrical shape up to the tip 57 as shown in FIG. 12 (d) are selected. It is possible. When the conical member 53 for expanding the diameter cannot be provided, a blind rivet can be used as the fixing insertion member 52.

さらに、図１３（ａ）や図１３（ｂ）に示すように、固定用挿入部材５２の大径頭部５２ｂにボルト（図示せず）を螺合可能な雌ねじ部５８を設けておくことにより、雌ねじ部５８にねじ込んだボルトを引っ張ることによって固定用挿入部材５２の先端部５２ａを縮径させながら拡底穴５１から固定用挿入部材５２を抜き取ることが可能となる。これにより、シール材２６の交換なども容易に行うことができる。なお、雌ねじ部５８を設ける場合、固定用挿入部材５２の先端部形状は、前記図１２（ａ）や図１２（ｂ）に示したスリット５４ｂ，５５ｂを設けたものとしておくことにより、固定用挿入部材５２を引き抜くときの先端部５２ａの縮径を容易に行うことができる。   Further, as shown in FIGS. 13A and 13B, by providing a female screw portion 58 capable of screwing a bolt (not shown) to the large-diameter head portion 52b of the fixing insertion member 52. By pulling the bolt screwed into the female screw portion 58, the fixing insertion member 52 can be extracted from the bottomed hole 51 while reducing the diameter of the distal end portion 52a of the fixing insertion member 52. Thereby, replacement | exchange of the sealing material 26 etc. can be performed easily. When the female screw portion 58 is provided, the distal end shape of the fixing insertion member 52 is fixed by providing the slits 54b and 55b shown in FIGS. 12 (a) and 12 (b). The diameter of the distal end portion 52a when the insertion member 52 is pulled out can be easily reduced.

図１４及び図１５は、弁本体２１及びシール材２６の他の形状例を示すもので、シール材２６におけるシール材本体３３の中央部に開口部２６ａを形成するとともに、該開口部２６ａに対応する弁本体２１の中央部に、開口部２６ａと嵌合する突出部２１ａを設けた例を示している。このように、弁のシールに関係のないシール材２６の中央部を開口させることにより、シール材２６を軟質ゴムで形成したときのゴム量を少なくすることができる。   FIGS. 14 and 15 show other examples of the shape of the valve body 21 and the sealing material 26. The opening 26a is formed at the center of the sealing material body 33 in the sealing material 26 and corresponds to the opening 26a. The example which provided the protrusion part 21a fitted to the opening part 26a in the center part of the valve main body 21 to perform is shown. Thus, by opening the central portion of the sealing material 26 that is not related to the valve seal, the amount of rubber when the sealing material 26 is formed of soft rubber can be reduced.

図１６及び図１７は、シール材２６の更に他の形状例を示すもので、シール材２６の挿通孔３４の開口縁部や内周面にリング状の突起部３４ａ，３４ｂ，３４ｃを形成した例を示している。このような突起部３４ａ，３４ｂ，３４ｃを設けることにより、前記固定用突部や固定用突出部材、固定用挿入部材とシール材２６とを確実に嵌合させることができ、シール材２６を所定の位置により確実に固定できるとともに、シール材２６をより確実に保持しておくことができる。なお、突起部３４ａ，３４ｂ，３４ｃは、挿通孔の大きさなどの条件によって異なるが、少なくとも一つを設けるだけでもよく、２つの突起部を適宜組み合わせて設けることもできる。   FIGS. 16 and 17 show another example of the shape of the sealing material 26, and ring-shaped protrusions 34a, 34b, and 34c are formed on the opening edge and the inner peripheral surface of the insertion hole 34 of the sealing material 26. FIG. An example is shown. By providing such protrusions 34a, 34b, and 34c, the fixing protrusion, the fixing protrusion member, the fixing insertion member, and the sealing material 26 can be securely fitted to each other, and the sealing material 26 is predetermined. It is possible to securely fix the sealing material 26 according to the position and to hold the sealing material 26 more reliably. In addition, although protrusion part 34a, 34b, 34c changes with conditions, such as the magnitude | size of an insertion hole, it is sufficient to provide at least one and can also provide it combining two protrusion parts suitably.
