きるという利点を備えた弁の構造に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention provides a large number of small holes dispersed in an orifice plate fixed to a valve box, and a plurality of small holes for adjusting the opening degree to the small holes. A certain valve element is provided so as to be vertically slidable between the valve opening position raised to the orifice plate and the valve closing position lowered to the orifice plate, and the small hole arranged at the lower part of the orifice plate is the valve element. A structure of a valve in which the orifice plate and the valve element are arranged relative to each other so that they are located within the vertical stroke range at the lower end, and more specifically, dust particles are mixed in the fluid and Even when it accumulates on the
If the deposit flows while being removed by the fluid flowing below the lower end of the valve body, the deposit will flow downstream through a small hole in the lower part of the orifice plate, and the fluid mixture will cause the valve body to slide up and down. The present invention relates to a structure of a valve having an advantage that it is possible to prevent the dynamic operation from being hindered.
従来の上記弁の構造は、弁体の流路方向から見た形状が
流路断面の形状に沿うものであった（たとえば実開昭60
−122068号公報第４図参照）。In the conventional structure of the above valve, the shape of the valve body as viewed from the flow path direction is in line with the shape of the cross section of the flow path (for example, in Japanese Utility Model No. Sho 60).
-1222068, see FIG. 4).
しかし、流体中の粉塵その他の流体混入物がオリフィス
プレートに付着したり、開弁中にも堆積物の除去が不十
分になったりして、弁体下端部と弁箱との間に粉塵その
他の流体混入物が挾まるような場合は、前記のように弁
体が流路断面の形状に沿うような流路方向から見た形状
であるために、弁体の下降の障害となって、弁体の上下
摺動操作が困難になる場合があった。However, dust or other fluid contaminants in the fluid may adhere to the orifice plate, or deposits may not be sufficiently removed even when the valve is open. In the case where the fluid mixture of is clogged, since the valve body has a shape viewed from the flow path direction along the shape of the flow path cross section as described above, it becomes an obstacle to the lowering of the valve body, In some cases, it was difficult to vertically slide the valve element.
本考案の目的は、このような場合にも弁体の上下摺動操
作を確実に維持できるようにする点にある。An object of the present invention is to ensure that the vertical sliding operation of the valve body can be maintained even in such a case.
本考案の弁の構造の特徴構成は、弁体の下端部を流路方
向から見て楔形形状にしてあることにあり、その作用効
果は、次の通りである。The characteristic structure of the structure of the valve of the present invention resides in that the lower end of the valve element is formed in a wedge shape when viewed from the flow path direction, and the operation and effect thereof are as follows.
つまり、弁体の下端部を流路方向から見て楔形形状にし
てあるので、仮に前記のように、弁体が下降しようとす
るときに弁体下端部と弁箱との間に粉塵その他の流体混
入物が挾まった場合にも、その楔効果によって、弁体下
端が挟まった流体混入物の中に容易に陥入するので、粉
塵その他の流体混入物によって弁体の上下摺動操作が阻
害されるのを回避できる。That is, since the lower end of the valve body is shaped like a wedge when viewed from the direction of the flow path, as described above, if the valve body is going to descend, dust or other particles will be present between the lower end of the valve body and the valve box. Even if the fluid mixture gets caught, the wedge effect easily causes the lower end of the valve body to slip into the fluid mixture, so dust and other fluid mixture can cause the valve body to slide up and down. You can avoid being hindered.
従って、流体内への粉塵その他の流体混入物の混入いか
んにかかわらず、弁体の上下摺動による弁開閉操作を維
持でき、流体の制御性能を、長期にわたって良好にでき
るようになった。Therefore, regardless of whether dust or other fluid contaminants are mixed in the fluid, the valve opening / closing operation by vertically sliding the valve body can be maintained, and the fluid control performance can be improved over a long period of time.
次に、本考案の実施例を、図面に基づいて説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.

が形成されるように構成してある。As shown in FIGS. 1 and 2, the orifice plate (2) fixed to the valve box (1) is connected to a large number of passages (R) in the valve box (1) for communicating the upstream side and the downstream side. The small holes (3) are provided dispersed in the vertical and horizontal directions at a predetermined pitch, and the small holes (3) are provided.
The valve body (5) provided with a large number of small holes (4) capable of simultaneously adjusting the opening of the group is placed in an opened valve position which is raised with respect to the orifice plate (2) and a closed valve position which is lowered. A valve rod (6) is slidably mounted on the valve box (1) to constitute a flow control valve, and the orifice plate (2) is provided.
The orifice plate (2) and the valve body (5) are relatively arranged so that the small hole (3) arranged in the lower part of the valve is located within the vertical stroke range of the lower end of the valve body (5), and the valve body (5) A part of the flow path (R) is formed below the lower end of the flow path when the opening / closing operation is performed.

ことができる。The lower end of the valve body (5) is shaped like a wedge when viewed from the flow path (R) direction, and as shown in FIG. If provided, even if fluid contaminants adhere to the orifice plate (2),
When the valve body (5) descends, the lower end of the valve body (5) works to push the adhered substances to the left and right, so that the resistance against the vertical sliding operation of the valve body (5) increases. Can be further reduced, so that the fluid control performance can be further stabilized.
