Description

本発明は、精密な圧力および流量調節が可能なコーンバルブに係り、さらに詳しくは、流量調節体を螺合方式で回転させることにより、流動抵抗を改善させるコーン部との間隔が微細に調節できるようにして、正確な圧力および流量の調節が可能であるとともに、時間が経過しても流量変動を起こさず、流動抵抗による空洞現象の発生が著しく減少することによりバルブおよび付随装置の耐久寿命が改善されるうえ、急激な流量変動による安全事故を防止するバルブに関する。   The present invention relates to a cone valve capable of precise pressure and flow rate adjustment, and more specifically, by rotating a flow rate adjusting body by a screwing method, the distance from the cone portion for improving flow resistance can be finely adjusted. In this way, the pressure and flow rate can be adjusted accurately, the flow rate does not fluctuate over time, and the occurrence of cavitation due to flow resistance is significantly reduced, thereby increasing the durability of valves and associated devices. The present invention relates to a valve that is improved and prevents a safety accident caused by a rapid flow rate fluctuation.

一般に、管路を流れる流体の流れを制御して流量を調節するバルブには、ボールバルブ、バタフライバルブ、ゲートバルブ、およびダイヤフラムバルブなどの様々な種類がある。特に、ボールバルブは、多く使用される類型のバルブであって、多様な形に製作されて使われている。   In general, there are various types of valves that adjust the flow rate by controlling the flow of fluid flowing through a pipeline, such as ball valves, butterfly valves, gate valves, and diaphragm valves. In particular, the ball valve is a type of valve that is frequently used, and is manufactured and used in various shapes.

特許文献１ではこのようなボールバルブの一例を開示する。特許文献１に開示されたボールバルブは、バルブ本体６の流路１の中央に設置され、貫通孔５を有するボール２と、ボール２の上部に嵌合され、流路１に対して垂直方向に設置されたステム３と、ステム３に一体に固定されたハンドル４と、ボール２と流路１との接触面に設置され、ボール２とバルブ本体６との間を気密させる弁座７とを含んでなる公知の流量制御ボールにおいて、前記ボール２の回転角度に対して、流路１に重畳するボール２の貫通孔５の面積が比例するようにすることを特徴とする。このような従来のボールバルブは、流量遮断用ハンドルを回すことにより、ボールが回転しながら流路を遮断または連結して流量を制御する。   Patent Document 1 discloses an example of such a ball valve. The ball valve disclosed in Patent Document 1 is installed in the center of the flow path 1 of the valve body 6, is fitted to the ball 2 having the through hole 5, and the upper part of the ball 2, and is perpendicular to the flow path 1. A stem 3 installed on the stem 3, a handle 4 fixed to the stem 3 integrally, and a valve seat 7 installed on the contact surface between the ball 2 and the flow path 1 to make the ball 2 and the valve body 6 airtight. In a known flow control ball including the above, the area of the through-hole 5 of the ball 2 superimposed on the flow path 1 is proportional to the rotation angle of the ball 2. In such a conventional ball valve, the flow rate is controlled by turning or connecting the flow path while the ball rotates by turning the flow rate blocking handle.

ところが、この種の従来のボールバルブは、次の問題点を抱えている。
１）ハンドルを回すことにより、ボールが回転しながら流路を連結させるため、流体の供給および遮断には効果があるが、精密に流量を調節することはできなかった。
２）精密な圧力または流量調節を行うために、ボールを全開にせず、ボールに設けられた流路が流体の流れに対して同一線上にくるようにする方法がある。ところが、このようにボールの流路がずれると、一時的には流路調節が可能であるが、流体の圧力によってボールが回転しながら「全開」或いは反対に「全閉」となり、流量または圧力の調節が全く不可能な状態になる。
これに加えて、急激に流路変動または圧力変動が発生すると、配管とポンプと付帯装置内の急激な圧力上昇により、必然的に急激な破壊によって安全事故が頻繁に発生し、安全弁を設置しても、安全弁を介して放出される多量の移送流体によって莫大な損失が発生する。
一方、精密な圧力または流量調節を行うために、ボールを全開にしないと、移送される流体の流線の流れが急激に変動して流体の圧力および速度が急激に変化して移送流体が蒸気圧以下に達し、これにより空洞現象（キャビテーション）が発生してバルブが完全に破壊される。
上述した空洞現象および移送流体の流動抵抗により流動騒音が大気中に拡散し、産業安全および産業環境を阻害する要素として台頭している。
３）ボールバルブにおいて必然的に発生する乱流の発生により、流体の流れに敏感な測定装備は設置することが難しかった。これを解決するためには、必ず乱流流れを層流化させる整流装置が必要であり、測定装備はこの整流装置から一定の直線距離を確保しなければならなかった。よって、付随的な装備の増設が必要となり、これにより設備空間が狭小なところには設置が不可能であった。 However, this type of conventional ball valve has the following problems.
1) By turning the handle, the flow path is connected while the ball rotates, so that it is effective in supplying and shutting off the fluid, but the flow rate cannot be adjusted precisely.
2) In order to perform precise pressure or flow rate adjustment, there is a method in which the ball is not fully opened, and the flow path provided in the ball is collinear with the fluid flow. However, if the flow path of the ball deviates in this way, the flow path can be temporarily adjusted. However, the ball rotates “full open” or conversely “full close” while rotating by the pressure of the fluid. Adjustment is impossible.
In addition to this, sudden flow path fluctuations or pressure fluctuations will inevitably cause frequent accidents due to sudden pressure rises in piping, pumps, and accompanying equipment, and safety valves are installed. However, enormous losses occur due to the large amount of transfer fluid released through the safety valve.
On the other hand, if the ball is not fully opened for precise pressure or flow rate adjustment, the flow line flow of the fluid to be transferred will fluctuate abruptly and the pressure and speed of the fluid will change abruptly, causing the transferred fluid to vaporize. Under pressure, this causes cavitation (cavitation) and the valve is completely destroyed.
Flow noise is diffused in the atmosphere due to the above-described cavity phenomenon and flow resistance of the transfer fluid, and it has emerged as an element that hinders industrial safety and the industrial environment.
3) Due to the turbulent flow that inevitably occurs in the ball valve, it was difficult to install measuring equipment sensitive to the fluid flow. In order to solve this problem, a rectifier that always makes the turbulent flow into a laminar flow is necessary, and the measurement equipment must ensure a certain linear distance from the rectifier. Therefore, it was necessary to add ancillary equipment, and it was impossible to install it in a place where the equipment space was narrow.

FIG. 1 is an exploded perspective view showing a disassembled state of each component to show the overall structure of the cone valve according to the present invention. FIG. 2 is a cross-sectional view showing a combined state of the cone valve according to the present invention. 3 is a cross-sectional view illustrating a gap adjusting state of the cone valves coupled according to the present invention. Here, reference numerals “P1” and “P2” respectively denote pipes in which the cone valve according to the present invention is installed.

本発明に係るコーンバルブ１００は、コーンバルブを設置するために対向して設置された一対のパイプＰ１、Ｐ２にそれぞれ装着される第１胴体１０および第２胴体３０、並びに一端が前記第１胴体１０に螺合され、該第１胴体１０に備えられたコーン部１２との間隔Ｇの調節によって微細流量を調節し、他端が前記第２胴体３０に圧入設置される流量調節体２０を含む。   The cone valve 100 according to the present invention includes a first fuselage 10 and a second fuselage 30 that are respectively attached to a pair of pipes P1 and P2 that are installed facing each other to install a cone valve, and one end of the first fuselage. A fine flow rate is adjusted by adjusting a gap G between the first body 10 and the cone portion 12 provided in the first body 10, and the other end includes a flow rate adjustment body 20 that is press-fitted to the second body 30. .

以下、これらの各構成要素別にさらに具体的に説明する。   Hereinafter, these components will be described more specifically.

第１胴体１０は、パイプＰ２に装着されるフランジ１６と、流体が流動できるように該フランジ１６から延在する流路１１とを含んでなる。   The first body 10 includes a flange 16 attached to the pipe P2 and a flow path 11 extending from the flange 16 so that a fluid can flow.

特に、流路１１には、内部に位置するようにコーン部１２が備えられる。コーン部１２は、第１胴体１０の製作の際に一体に設けられるが、この流路１１を介して流入した流体がフランジ１６を介して抜け出すように複数の吐き出し口１２ａを有する。一例として、このような吐き出し口１２ａは、コーン部１２がフランジ１６の中央に三脚台の形状に支持されるように第１胴体１０を形成することにより各脚の間に設けられる。また、このようなコーン部１２は第１胴体１０に一体に設けられていると説明しているが、分離型に製作し、フランジ１６に対して着脱することが可能な構造にすることも可能である。   In particular, the channel 11 is provided with a cone portion 12 so as to be located inside. The cone portion 12 is integrally provided when the first body 10 is manufactured. The cone portion 12 has a plurality of discharge ports 12 a so that the fluid flowing in through the flow path 11 flows out through the flange 16. As an example, such a discharge port 12 a is provided between the legs by forming the first body 10 so that the cone portion 12 is supported in the shape of a tripod base at the center of the flange 16. In addition, although it has been described that such a cone portion 12 is provided integrally with the first body 10, it is possible to make the cone portion 12 so as to be detachable from the flange 16. It is.

また、流路１１は、内周面の入口部にネジ部１３が設けられ、このネジ部１３の内側には条溝１４が設けられる。この際、ネジ部１３は、後述の流量調節体２０に螺合される。条溝１４は、少なくとも一つ設けられてシーリング１４ａが取り付けられることにより、流路１１に嵌合された流量調節体２０との間から流体が漏れることを防止する。
流路１１には、外周面に固定孔１５が貫設される。この際、前記固定孔１５は流路１１に嵌合された流量調節体２０と重畳する位置に設けられる。これは、前記固定孔１５に固定ネジ１５ａを締結することにより第１胴体１０に流量調節体２０を一体に固定させるためである。
一方、フランジ１６は、パイプＰ２のフランジと同一の直径を有し、その一面には締結孔１６ａが設けられる。この締結孔１６ａは、パイプＰ２のフランジに設けられた締結孔との対応位置に穿設され、フランジ同士の結合に使用される。勿論、フランジ１６は直ちにパイプに溶接などの方法で連結して使用することも可能である。また、図示してはいないが、フランジ１６にはパイプＰ２と対向する面にシーリングのための条溝をさらに設けてもよい。
流量調節体２０は、流体の流動が可能であり、一端には斜面２４が設けられた締結管路部２１と、該締結管路部２１に一体に延在している圧入管路部２２と、前記締結管路部２１と前記圧入管路部２２との連結部位に突設された装着フランジ部２３とを含んでなる。
締結管路部２１は、前記流路１１の内径と同一の外径を有し、外周面には前記ネジ部１３と締結できるように雄ネジ部２１ａが設けられる。締結管路部２１には、流路１１の内側に挿入される端部に前記コーン部１２を取り囲む形で斜面２４が設けられる。この際、斜面２４はコーン部１２とは一定の間隔Ｇを持つ。
圧入管路部２２は締結管路部２１に延設される。この際、圧入管路部２２は後述する第２胴体３０の内径と同一の外径を有する。このような圧入管路部２２は第２胴体３０にシーリングによって締まり嵌め方式で圧入設置される。
装着フランジ部２３は、締結管路部２１と圧入管路部２２との間に設けられる。特に、前記装着フランジ部２３の外周面には等間隔で溝部２３ａが設けられる。この溝部２３ａはケーブルレンチの溝が挿入されるようにして装着フランジ部２３を回転させるときに使用される。勿論、この溝部２３ａには突起を挿入してチェーン等が掛かるようにして装着フランジ部２３を回転させるようにしてもよい。また、前記溝部の代わりにギア噛合によって装着フランジ部を回転させてもよい。
第２胴体３０は、前記圧入管路部２２に外嵌される管部３１と、この管部３１の一側に設けられ、パイプＰ１に連結されるフランジ部３２とを含んでなる。
特に、管部３１には内部に条溝３３が設けられ、この条溝にはシーリング３３ａが取り付けられる。このような条溝３３は、本発明に係るボールバルブ１００の大きさを考慮し、流動する流体の圧力に応じて複数設けられる。図面では２つの条溝が設けられた例を示す。
フランジ部３２は、パイプＰ１に連結されるが、ネジ方式で締結する場合には締結孔３２ａをさらに設けてもよい。このような締結方式は通常の技術によって行われるので、ここではその詳細な説明を省略する。
（作動）
このように構成された本発明に係るコーンバルブ１００は、流量調節が必要な場合、固定ネジ１５ａを弛緩させ、第１胴体１０に固定された流量調節体２０が回転可能な状態にしておく。
次いで、流量調節体２０を回転させる。このときの回転は、条溝２３ａにケーブルレンチなどを挿入して流量調節体２０を回転させることにより行われる。一方、装着フランジ部２３の外周面にギアを設けて前記流量調節体２０を回転させることも可能である。
これにより、締結管路部２１は第１胴体１０に螺合により締結されて回転し、圧入管路部２２はシーリング３３ａによって漏れが防止された状態で第２胴体１０に圧入されて回転する。 Further, the flow path 11 is provided with a screw portion 13 at an inlet portion of an inner peripheral surface, and a groove 14 is provided inside the screw portion 13. At this time, the screw portion 13 is screwed into a flow rate adjusting body 20 described later. At least one groove 14 is provided and a sealing 14 a is attached, thereby preventing fluid from leaking from between the flow rate adjusting body 20 fitted in the flow path 11.
A fixed hole 15 is provided through the outer peripheral surface of the flow path 11. At this time, the fixing hole 15 is provided at a position overlapping the flow rate adjusting body 20 fitted in the flow path 11. This is because the flow rate adjusting body 20 is integrally fixed to the first body 10 by fastening the fixing screw 15 a to the fixing hole 15.
On the other hand, the flange 16 has the same diameter as the flange of the pipe P2, and a fastening hole 16a is provided on one surface thereof. The fastening hole 16a is formed at a position corresponding to the fastening hole provided in the flange of the pipe P2, and is used for joining the flanges. Of course, the flange 16 can be used by being immediately connected to the pipe by welding or the like. Although not shown, the flange 16 may further be provided with a groove for sealing on the surface facing the pipe P2.
The flow rate adjusting body 20 is capable of fluid flow, and has a fastening pipe line portion 21 provided with an inclined surface 24 at one end, and a press-fit pipe line portion 22 extending integrally with the fastening pipe line portion 21. And a mounting flange portion 23 projecting from a connecting portion between the fastening pipe line portion 21 and the press-fitting pipe line portion 22.
The fastening conduit portion 21 has the same outer diameter as the inner diameter of the flow passage 11, and a male screw portion 21 a is provided on the outer peripheral surface so as to be fastened to the screw portion 13. The fastening conduit portion 21 is provided with an inclined surface 24 at the end portion inserted into the flow passage 11 so as to surround the cone portion 12. At this time, the inclined surface 24 has a certain distance G from the cone portion 12.
The press-fitting pipe line part 22 is extended to the fastening pipe line part 21. At this time, the press-fit pipe line portion 22 has the same outer diameter as the inner diameter of the second body 30 described later. Such a press-fitting pipe line part 22 is press-fitted and installed in the second body 30 by sealing and fitting.
The mounting flange portion 23 is provided between the fastening pipeline portion 21 and the press-fit pipeline portion 22. In particular, the outer peripheral surface of the mounting flange portion 23 is provided with groove portions 23a at equal intervals. The groove 23a is used when the mounting flange 23 is rotated so that the groove of the cable wrench is inserted. Of course, the mounting flange 23 may be rotated by inserting a protrusion into the groove 23a so that a chain or the like is hooked. Further, the mounting flange portion may be rotated by gear meshing instead of the groove portion.
The second body 30 includes a pipe part 31 fitted on the press-fit pipe line part 22 and a flange part 32 provided on one side of the pipe part 31 and connected to the pipe P1.
In particular, the pipe portion 31 is provided with a groove 33 inside, and a sealing 33a is attached to the groove. In consideration of the size of the ball valve 100 according to the present invention, a plurality of such grooves 33 are provided according to the pressure of the flowing fluid. The drawing shows an example in which two grooves are provided.
The flange portion 32 is connected to the pipe P1, but a fastening hole 32a may be further provided when fastening by a screw method. Since such a fastening method is performed by a normal technique, detailed description thereof is omitted here.
(Operation)
In the cone valve 100 according to the present invention configured as described above, when the flow rate adjustment is necessary, the fixing screw 15a is loosened so that the flow rate adjustment body 20 fixed to the first body 10 is rotatable.
Next, the flow control body 20 is rotated. The rotation at this time is performed by inserting a cable wrench or the like into the groove 23a and rotating the flow rate adjusting body 20. On the other hand, a gear may be provided on the outer peripheral surface of the mounting flange portion 23 to rotate the flow rate adjusting body 20.
As a result, the fastening pipe line portion 21 is fastened and rotated by being screwed to the first body 10, and the press-fit pipe line part 22 is press-fitted into the second body 10 and rotated while being prevented from leaking by the sealing 33 a.

一方、流量調節体２０は、このような回転によって第１胴体１０の長さ方向に動き、これによりコーン部１２と斜面２４との間隔Ｇが異なる。
この際の間隔Ｇは調節しようとする流量によって異なる。このような間隔Ｇは、流量調節体２０の回転量を長さで変換させるため、微細調節も可能である。
最後に、流量調節が終わると、固定ネジ１５ａをさらに締結して第１胴体１０に流量調節体２０を固定させる。
上述したように、本発明は、螺合方式で長さが調節される流量調節体がコーン部との間隙調節によって流量を調節し得るようにすることにより、構造が簡単であるうえ、正確かつ精密に微細流量調節が可能である。 On the other hand, the flow rate adjusting body 20 moves in the length direction of the first body 10 by such rotation, and thus the gap G between the cone portion 12 and the inclined surface 24 is different.
The interval G at this time varies depending on the flow rate to be adjusted. Such an interval G can be finely adjusted because the rotation amount of the flow rate adjusting body 20 is converted by the length.
Finally, when the flow rate adjustment is completed, the fixing screw 15a is further tightened to fix the flow rate adjustment body 20 to the first body 10.
As described above, the present invention is simple in structure, accurate and accurate by allowing the flow rate adjusting body whose length is adjusted by the screwing method to adjust the flow rate by adjusting the gap with the cone portion. Precise fine flow rate adjustment is possible.
