Normally, rotary valves, ball valves, slide valves, and the like are used to extract powder particles downstream from powder storage or production facilities such as tanks, silos, and hoppers. Slide valves are frequently used because of their simple structure and low cost. FIG. 5 shows a prior art, and a malfunction is often caused due to the accumulation of powder particles between the slide valve valve plate 4, the valve holding upper guide rail 1, and the lower guide rail 2. Further, every time the valve plate is actuated between the upper holding rail 3 and the lower holding rail 9 at the valve plate abutting portion, the granular material is pushed in, and the granular material accumulates, resulting in poor closing. In Patent Document 1, the valve plate is inserted and removed obliquely from above.
JP 2002-68482 A

しかしながら、以上の従来技術によれば、弁摺動型のバルブでは、主として両サイドのガイドレールとスライド弁板との間に摺動時に粉粒体を噛み込み、作動不良により開閉不能になる。   However, according to the prior art described above, in the valve sliding type valve, the powder and granule are bitten mainly during sliding between the guide rails on both sides and the slide valve plate, and cannot be opened or closed due to malfunction.

バルブ全閉時スライド弁板突当り部、弁開閉の度に、上下レールの間に粉粒体を押込み、その堆積がレールのレベルを超すと全閉不能となる。   When the valve is fully closed, each time the valve contacts the slide valve plate, the granule is pushed in between the upper and lower rails. If the accumulation exceeds the level of the rail, it cannot be fully closed.

そこで、この発明は、このような従来技術の有する課題に鑑みてなされたもので、目的とするところは、噛み込み、押込みによるバルブの作動不良をなくし、それによる生産設備の停止、又は抜出し時間の延長による納入時間遅れ等を解消できるバルブを提供することを課題とする。   Therefore, the present invention has been made in view of such problems of the prior art, and the object is to eliminate the malfunction of the valve due to biting and pushing, and thereby stop the production facility or take it out. It is an object to provide a valve that can eliminate the delay in delivery time due to the extension of the time.

以上の課題を解決するために、請求項1の発明は、バルブ弁室内、スライド弁板保持用側面ガイドレールの内、上側のレールは連続とし、下側のレールは切り込みを入れて飛石状に配置する。弁板と飛石状にした下側レールとの突当り停止防止の為、弁板の縁と最初に接する側のレールの角をとることを特徴とする粉粒体用スライドバルブ。   In order to solve the above problems, the invention according to claim 1 is that the upper rail is continuous among the valve valve chamber and the side guide rail for holding the slide valve plate, and the lower rail is cut into a stepping stone. Deploy. A slide valve for a granular material, characterized by taking the corner of the rail on the side that first contacts the edge of the valve plate in order to prevent the valve plate from striking and stopping between the stepping rail and the lower rail.

請求項2の発明は、弁室フレームとガイドレールの間に空間を作る。下側のレールとフレームの間の空間に粉粒体が堆積せず滑り降りるように、飛石状レールの上部中間を頂点に、切れ目の下縁まで三角形に埋めることを特徴とする請求項1の粉粒体用スライドバルブ。   The invention of claim 2 creates a space between the valve chamber frame and the guide rail. 2. Granules according to claim 1, characterized in that the upper middle part of the stepping stone rail is buried in a triangle up to the apex and the lower edge of the cut so that the powder particles do not accumulate in the space between the lower rail and the frame. Body slide valve.

請求項3の発明は、スライド弁板進行方向正面の、上側レールとフレームの間に空間を作り、下側レールを、全部カットすることを特徴とする請求項1、2の粉粒体用スライドバルブ。   The invention according to claim 3 is characterized in that a space is formed between the upper rail and the frame in front of the slide valve plate in the traveling direction, and the lower rail is entirely cut. valve.

以上説明したように、この発明によれば、タンク、サイロ、ホッパー等の粉粒体貯蔵又は生産設備より粉粒体を下流側へ抜出するバルブは、スライド弁板保持用のガイドレールと、スライド弁板の間に、噛み込みによりスライド弁板摺動不良、突当り部溝詰まりによる全閉不良が無くなり、それによる生産設備停止、積み込み時間の延長が無くなり、生産計画、納入計画設定と達成に、生産設備と製品納入用車両の稼働率向上に役立っている。   As described above, according to the present invention, the valve for extracting the granular material to the downstream side from the granular material storage or production equipment such as a tank, silo, hopper, and the like, the guide rail for holding the slide valve plate, Clogging between slide valve plates eliminates sliding valve plate sliding failure and full closure failure due to clogging of the groove at the abutment. It helps to improve the availability of equipment and product delivery vehicles.

本発明を実施するに当たり、弁室とスライド弁板の間のシール形態は、粉粒体の種類により、グランドパッキン、シールゴム等粉粒体に合った形態、材質を使用する。   In carrying out the present invention, the seal form between the valve chamber and the slide valve plate uses a form and material suitable for the granular material such as gland packing and seal rubber depending on the type of the granular material.

この発明の実施例1を、図1に示す。タンク、サイロ、ホッパー等の粉粒体貯蔵又は生産設備より、粉粒体を下流側へ抜出するバルブの一実施例概略図である。粉粒体を下流側に抜出し時、スライド弁板4の摺動により、若干の粉粒体がスライド弁板4と側面上レール1と側面下レール2の間に噛み込む、噛み込まれた粉粒体は、スライド弁板4の摺動につれ、上レール1とスライド弁板4の間はフレーム6との間にある空間5に落下する、落下した粉粒体は、下レール2とフレーム6との間の空間を埋める三角形突起7(図4)の上を滑り、下レール2の切れ目より弁室内に排出する。下レール2とスライド弁板4の間の噛み込みは、下レール2の切れ目と、空間5に排出し、作動不良を起こすような堆積は起こらない。   A first embodiment of the present invention is shown in FIG. It is one Example schematic of the valve | bulb which extracts a granular material downstream from granular material storage or production facilities, such as a tank, a silo, and a hopper. When the powder particles are extracted downstream, some powder particles are caught between the slide valve plate 4, the side upper rail 1 and the side lower rail 2 by the sliding of the slide valve plate 4. As the slide valve plate 4 slides, the granules fall into a space 5 between the upper rail 1 and the slide valve plate 4 and the frame 6. The dropped powder granules fall between the lower rail 2 and the frame 6. It slides on the triangular protrusion 7 (FIG. 4) that fills the space between and the lower rail 2 and is discharged into the valve chamber. The biting between the lower rail 2 and the slide valve plate 4 is discharged to the break of the lower rail 2 and the space 5 and does not accumulate so as to cause a malfunction.

バルブ閉時、スライド弁板4突当り部は、上レール3のみで下レールが無く、フレーム6との間に空間5があるため、開閉作動時、スライド弁板4が押込んだ粉粒体は、空間5を通して弁室内に落下するので埋めることは無く、堆積が出来ず、閉不良を起こさない。   When the valve is closed, the contact portion of the slide valve plate 4 is only the upper rail 3 and there is no lower rail, and there is a space 5 between the frame 6. Since it falls into the valve chamber through the space 5, it is not filled, cannot be deposited, and does not cause poor closing.

バルブ開動作時スライド弁体に乗っている粉粒体は、横一線のバルブフレームの縁8により擦り取られ、多少の噛み込みがあっても厚みがないため、これにより作動不良を起こすような堆積は無い。   The granular material on the slide valve body when the valve is opened is scraped off by the edge 8 of the horizontal valve frame, and there is no thickness even if there is a slight bite. There is no accumulation.
