６とから構成されている。In general, the gate valve 100 has an inlet 101 and an outlet 102 formed at the front and rear, as shown in FIG.
A valve body 10 that is equipped with a valve body 104 having two valve body seats NO3, 103, and valve body seats 105, 105 that sit on both valve body seats 103, 103 when fully closed, and that is movable up and down.
It consists of 6.
ところがこの様な形式の仕切弁１００に於ては、弁箱１

。However, in the gate valve 100 of this type, the valve box 1
A bag portion 107 is provided at the bottom of both valve box seats 103, 103 of 04.
Since sludge is inevitably formed, sludge tends to be deposited here, which greatly impedes the vertical movement of the valve body 106 and the sealing effect, making it impossible to handle water containing sludge.
即ち、前記袋部１０７が流体の流路から分離された状態
となっているため、沈積した汚泥が流体内へ簡単に流れ
出ず、当該袋部１０７内に順次溜ることになる。That is, since the bag portion 107 is separated from the fluid flow path, the deposited sludge does not easily flow out into the fluid, but gradually accumulates in the bag portion 107.
本考案が解決しようとする技術的課題は、仕切弁の機能
を持った状態で上記の袋部分を取り去り、汚泥を含んだ
流体を取扱うことができるようにする点にある。The technical problem to be solved by the present invention is to remove the bag portion while still having the function of a gate valve so that fluid containing sludge can be handled.

動機構１０とを、仕切弁の基本構成としている。In order to solve the above technical problem, in this invention,
It has an inlet 2 and an outlet 3 at the front and rear, and a passage 13 on the inlet side.
The downstream side of the passageway 13 is curved upward by a mirror angle θ with respect to the horizontal direction, and its upper end is communicated with the hollow portion 14 of the lid body 12, and a partition inclined at the mirror angle θ is provided on the upper wall of the curved portion of the passage 13. A valve box 4 having an opening 5 formed therein and communicating with the outflow side passage 15; A valve box seat 6 attached around the partition opening 5 in the valve box 4; A valve box seat 6 corresponding to the valve box seat 6; Valve body seat 7 and wedge abutting portion 2 with an inclined back surface
a valve body 8 which is slidably inserted into the valve box 4 to open and close the partition opening 5; The valve body 8 is in contact with the portion 27.
a wedge 26 that presses the valve body toward the valve box seat 6; and a lid body 1.
A drive mechanism 10 that moves the valve body 8 up and down via a valve rod 21 inserted through the gate valve is the basic structure of the gate valve.

去られることになり、万一閉弁時に流体内の汚損が弁体
シートの下方に溜っていても、開弁時には流体によって
洗い流される。In the present invention, an inlet and an outlet are provided at the front and rear, and the downstream side of the passage on the inlet side is curved upward by an obtuse angle θ with respect to the horizontal direction, and the upper end thereof is communicated with the hollow part of the lid body.
The valve box has a partition opening inclined at an obtuse angle θ with respect to the horizontal direction on the upper wall of the curved part of the passage on the inlet side, and the outflow side passage is communicated with this.
The lower part of the valve body sheet that is fixed around the partition opening becomes a continuous curved surface that forms a fluid flow path, and the bag portion is completely removed. Even if it accumulates below the seat, it will be washed away by the fluid when the valve is opened.
その結果汚泥の沈積によるシール性能の悪化や弁体の昇
降性能の悪化が完全に防止されることになる。As a result, deterioration of the sealing performance and deterioration of the lifting performance of the valve body due to sludge deposition can be completely prevented.
又、仕切開口の周囲に弁箱シートを取付けると共に、該
弁箱シートに対応する弁体シートを備え且つその背面に

のウェッジ当合部とを接当させるようにしているため、
弁体シートが弁箱シート側へ均一に押圧されることにな
り、シール性能が著しく向上することになる。Further, a valve body seat is attached around the partition opening, and a valve body having a valve body seat corresponding to the valve body seat and having a wedge abutting portion of an inclined surface on the back side thereof is tilted at the angle θ. It is inserted into the hollow part of the lid body so that it can slide automatically, and when the valve □ is fully closed, the wedge arranged separately inside the valve body and the wedge abutting part on the back of the valve body come into contact.
The valve body seat is evenly pressed toward the valve box seat, and the sealing performance is significantly improved.
本考案ではウェッジ機構を採用することにより、弁箱シ
ートと弁体シートを各一枚づつとしているため、汚泥等
の噛込みによる損傷の頻度が少なくなる。In the present invention, by employing a wedge mechanism, there is one valve box seat and one valve body seat, which reduces the frequency of damage caused by sludge and the like.
又、仕切開口を流出口側へ傾斜させているため、弁の全
高を低くできると共に、弁体を垂直方向に昇降させる場
合に比較して、弁体駆動力が少なくてよい。Furthermore, since the partition opening is inclined toward the outlet side, the overall height of the valve can be reduced, and the driving force for the valve element can be reduced compared to when the valve element is moved up and down in the vertical direction.
