ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for measuring a flow of a suspension of finely ground coal particles in a liquid organic medium in a liquefaction reaction of solid particles into a liquid organic medium. This relates to the structure of the valve.

A type of valve is used in which the flow path is closed by bringing the edge 33 of the valve seat into contact with the edge 21 of the valve seat.

さるので、特に高圧液体の流にＡ箇に賞用されている。This type of valve supports the valve stem below the valve seat to suppress the vibration of the valve stem during use, and is therefore particularly useful for the flow of high-pressure liquids. ing.

えなくなる。However, such a valve can be used to control the flow of a solid particle suspension, such as a suspension of pulverized coal particles in a liquid organic medium, for example in a coal liquefaction reaction! - When used to examine - This creates a vortex flow and solid particles imperceptibly collide with the wall of the valve body nearby (the part indicated by symbol A in Figure 3), so the wall of the valve body is worn out so hot that it becomes unusable after about 2000 hours.

された部分を４１するように構成されている。Structure of the Invention I One Modification The flow spear control valve for solid particle suspension of the present invention has a ring-shaped valve seat provided in the valve body. An annular wave path is formed between the inner wall of the valve seat and the outer wall of the valve rod by penetrating the rod, and the lower edge of the enlarged portion of the valve rod provided at 1:rB from the penetrating portion and 1-1 of the valve seat. In a type of valve that closes the flow path by making contact with the edge of the valve, the valve stem is smoothly narrowed in a curved line from the location corresponding to the edge of the valve seat at the maximum opening of the valve, resulting in an even smaller diameter. 11 The valve body is constructed such that the widened part is 41 aligned with the line of the lower edge of the valve seat.

The structure of the internal wall is unique, and the structure of other parts is tertiary.
It can be the same as shown in the figure.

た状態。The rod 3 has a portion 31 with an outer diameter smaller than the inside diameter of the valve seat 2, and this portion passes through the valve seat 2 to form an annular flow path between the inner wall of the valve seat 2 and the outer wall of the valve stem 3. 4, and is configured to close the flow path by bringing the lower edge 33 of the enlarged portion 32 of the valve stem provided above the penetrating portion into contact with the upper edge 21 of the valve seat. Figure 1 shows a state in which the flow path is closed and the valve is closed.

小さな径の部分３５となるように構成されている。In the present invention, the valve stem l is smoothly narrowed in a curved manner as shown by symbol 34 from a location (B) corresponding to the lower edge 22 of the valve seat 2 in the maximum opening state of the valve shown in FIG. It is configured to have a small diameter portion 35.
さらに、弁体ｌは弁座の下縁２２の線に揃えて拡幅され
た部分１１を有するように構成されている。Further, the valve body l is configured to have a widened portion 11 aligned with the line of the lower edge 22 of the valve seat.

ある。The main idea regarding the structure of this annular flow path outlet part is that the solid particle suspension that has flowed through the annular flow path exits the annular flow path, and one side (the wall side of the valve body) is a part of the wall. There is a smooth curved surface (on the valve stem side) on the other side (valve stem side).
(consisting of the rod itself).

ている。The width of the JO-shaped flow path is the same even in an intermediate opening degree of JR, that is, an intermediate state between the states shown in FIGS. There is a free space with no curves, and on the side of the valve body there is a smoothly narrowed curved surface formed by the valve stem itself (via the straight part of the valve stem).

It exhibits a property known as the Coanda effect.

の場合環状流路４から「１白布間へ出た液流は矢印Ｃで
示す如くｊｒｒＢの曲線的に滑らかに絞られた壁面３４
に添って流れるようになる。The Coanda effect is a phenomenon in which when a fluid flowing in an n-small space touches a curved surface, it flows along the curved surface. As shown in C, the wall surface 34 of jrrB is curved smoothly.
It starts to flow along with the flow.

の使用に耐えるようになる。1-Concave As mentioned above, the solid particle suspension flowing at high speed through the annular flow path when the valve is opened flows through the smoothly curved wall surface of the 5R rod present in the annular flow step 11 due to the Coanda effect. The Coanda effect appears more strongly as the flow velocity of the fluid flowing through the annular space increases, so the Coanda effect becomes stronger as the valve is opened, and the liquid flow becomes more blurred.
As the flow approaches the rod side, the collision of solid particles with the inner wall of the valve body is significantly reduced, and the valve body has less force, making it durable for long-term use.
