出来たものである。When handling slurry or polymerizable fluids in remote-controlled control valves using air pressure, electromagnetic force, etc., conventionally, the solid content of the slurry clogs the slit-like gap between the guide ring of the inner valve part and the cylindrical valve plug, or It often happens that the valve becomes inoperable due to accumulation of polymerizable liquid and clogging of the polymer, and the inventors of the valve have conducted intensive studies on this point each time, and as a result, they have arrived at the present invention. It was possible to solve the problem.

特徴とするものである。That is, the control valve according to the present invention is a remote control control valve in which the guide portion of the valve plug in the inner valve part has a polygonal cross-sectional shape such as a quadrangle, pentagon, hexagon, heptagon, or rectangular shape, and the guide ring and valve plug have a cross-sectional shape. The feature is that a flushing liquid is flowed in between to prevent the part from sticking due to slurry, polymerizable fluid, or the like.

問題のないものを使用する。The present invention will now be explained with reference to the drawings. In the angle valve shown in FIG. 1, the pulp stem 1 is driven by air pressure or the like, and the valve plug 2.3 is moved up and down to open and close the valve. The cross-sectional shape of the valve plug 3 in contact with the guide ring 4 is preferably about 4 to 8 squares, and as shown in FIG. (σ) The flush liquid introduced from the flush liquid nozzle 5 into the arcuate cross-sectional gap between the guide link 4 and the valve plug 30 is contaminated.The flag fluid used is one that does not cause problems even if mixed with the solvent of the handled fluid. do.

Angle valve B is used, and the guide portion of the conventional valve plug had a circular cross section, and the only gap between it and the guide ring was a slit-like clearance.

メンテナンス面での費用節減効果も大であった。Therefore, we injected a flush liquid to avoid the risk of sticking due to polymers, but even so, the guide ring and valve plug still stuck due to polymers 4 to 5 times a year, and the control valve was overhauled each time. However, when the guide part of the valve plug of this control valve was modified to have a regular hexagonal cross section as shown in Figures 1 and 2 and flush liquid was injected, no sticking occurred even after one year. The cost savings in terms of maintenance were also significant.
