本考案はアルカリ性、酸性のスラリもしくは溶液等の流
量制御に適したアルミナ磁器質バルブの改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement of an alumina porcelain valve suitable for controlling the flow rate of alkaline or acidic slurries or solutions.
従来、この種の流量制御に用いられるアルミナ磁器質バ
ルブとしては第１図に示す構造のものが知られている。Conventionally, as an alumina porcelain valve used for this type of flow rate control, one having the structure shown in FIG. 1 is known.
すなわち、図中１は流入口２、流出口３を有し、かつ流
入口２近傍に弁座４が設けられたケーシングである。That is, 1 in the figure is a casing having an inlet 2 and an outlet 3, and a valve seat 4 provided near the inlet 2.
そして、上記ケーシング１の左側部から先端に弁体５を
取付けた金属製スピンドル６が進退可能に挿入されてい
る。A metal spindle 6 having a valve body 5 attached to its tip is inserted from the left side of the casing 1 so as to be movable forward and backward.

ンドル６先端部に弁体５を連結、取着している。The spindle 6 and the valve body 5 are attached by having the spindle 6, which has a stopper 7 at its tip, pass through the insertion hole 8 of the valve body 5. The valve body 5 is connected and attached.
しかしながら、かがる構造のアルミナ磁器質バルブにあ

たスピンドル６のストッパー７に接触し、そのストッパ
ー７が著しく摩耗され、長期間の使用に耐えられない欠
点があった。However, in an alumina porcelain valve with a bending structure, the stopper 7 at the tip of the metal spindle 6 is attached to the valve body 5.
Because it is exposed from the tip of the casing 1, alkaline, acidic slurry, etc. can be controlled by the valve body 5.
When flowing through the inside, the slurry or the like having a high flow rate comes into contact with the exposed stopper 7 of the spindle 6, and the stopper 7 is considerably worn out, which has the disadvantage that it cannot withstand long-term use.
このようなことから、金属製スピンドルの先端にアルミ
ナ磁器製の弁体をその弁体先端部にスピンドルが露出し
ないように固定して一体構造物としたものが試作された
が、ヒートショックやスピンドルと弁体との熱膨張差に
よりしばしば弁体にクラックが発生する不都合さがあっ
た。For this reason, an integrated structure was prototyped in which an alumina porcelain valve body was fixed to the tip of a metal spindle so that the spindle would not be exposed to the tip of the valve body. There is an inconvenience that cracks often occur in the valve body due to the difference in thermal expansion between the valve body and the valve body.
また、バルブケーシング内をスラリー等が通過する際、
弁体に対して強い抵抗と複雑な振動が加わるため、弁体
とスピンドルが剥れ易い欠点があった。Also, when slurry etc. passes through the valve casing,
Since strong resistance and complex vibrations are applied to the valve body, the valve body and spindle tend to separate easily.
本考案は上記欠点に鑑みなされたもので、弁体を弁本体

である。The present invention was developed in view of the above-mentioned drawbacks.The valve body is divided into a valve body and a cap, and the tip of the spindle is embedded and fixed in the cap, thereby preventing spindle wear, heat shock, and thermal expansion. The object of the present invention is to provide an alumina porcelain valve that can prevent defects caused by.
以下、本考案の一実施例を第２図及び第３図を参照して
詳細に説明する。Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3.

１内には例えばアルミナ磁器質の弁座１４が設けられて
いる。In the figure, reference numeral 11 denotes a metal valve casing, and an inlet 12 is provided on the right side of the casing 11, and an outlet 13 is provided on the lower part of the casing 11.
A valve seat 14 made of, for example, alumina porcelain is provided within the valve seat 1 .
そして、上記ケーシング１１の左側部側から先端に弁体
１５を取付けた金属製のスピンドル１６を進退可能に挿
置している。A metal spindle 16 having a valve body 15 attached to its tip is inserted from the left side of the casing 11 so as to be movable back and forth.

いる。As shown in FIG. 3, this valve body 15 has a cylindrical fitting hole 17 at the tip and a valve body 19 made of alumina porcelain with a through hole 18 provided approximately in the center, and the valve body 19 is inserted into the rear end. It is divided into a cap 21 made of alumina porcelain and a cap 21 made of alumina porcelain in which a hole 20 is bored.
前記キャップ２１の挿入孔２０には前記スピンドル１６

ピン２４により連結固定されている。The spindle 16 is inserted into the insertion hole 20 of the cap 21.
is inserted, and these cap 21 and spindle 1
6 is a pin insertion hole 2 perpendicular to the axial direction of the cap 21.
2 and the spindle 16 are connected and fixed by a connecting pin 24 passing through a through hole 23 at the tip of the spindle 16.

ドル１６先端に取着される。Further, the cap 21 and the valve body 18 are arranged so that the spindle 16 connected to the cap 21 is connected to the through hole 1 of the valve body 19.
8 and fit the rear end portion of the cap 21 into the fitting hole 17 of the valve body, and also insert the metal fitting 25 from the rear end side of the spindle 16 and tighten it by screwing the metal fitting 25 into contact with the rear end surface of the valve body 19. The valve body 15 is connected and integrated by connecting and tightening, and the valve body 15, which is made of alumina porcelain up to the portion including the tip, is attached to the tip of the spindle 16.
このような構成によれば、今、ケーシング１１の流入口
１２から酸性のスラリー等を流入した状態でスピンドル

の弁座１４に近接させると、スラノーは弁体１５と弁座
１４の間で流量が制御された状態でケーシング１１内に
流通する。According to such a configuration, the spindle 16 is entered with acidic slurry or the like flowing in from the inlet 12 of the casing 11, and the valve body 15 at the tip thereof is inserted into the casing 11.
When the sullano is brought close to the valve seat 14 of the valve body 15, the flow rate is controlled between the valve body 15 and the valve seat 14, and the sullano flows into the casing 11.
この際、スラノーは流速が早められた状態で弁体１５の
先端に接触するが、金属製のスピンドル１６の先端は弁

なうスピンドル１６先端の摩耗を防止できる。At this time, the sulannow comes into contact with the tip of the valve body 15 in a state where the flow velocity is accelerated, but the tip of the metal spindle 16 is embedded and fixed in the cap 21, which is one of the divided bodies of the valve body 15. Since the tip of the spindle 16 is not exposed to the outside from the tip of the valve body 15, wear of the tip of the spindle 16 due to contact with acidic slurry can be prevented.

ラック発生を防止できる。Further, since the valve body 15 is divided into a valve body 19 and a cap 21 to which the spindle 16 is fixed, and these are integrated by a gap fit, heat shock and the difference in thermal expansion between the spindle 16 and the valve body 15 can be avoided. It is possible to prevent the occurrence of cracks in the valve body 15 due to this.
