That is, it is a structure in which all the force that the upper lid tries to open due to the water pressure in the valve is supported by the bolt. For this reason, a large force acts on the bolts, so the number of bolts must be increased and the bolt diameter must be increased, and a large flange is required. Become big. In addition, many parts such as bolts, nuts, washers, and sealing materials are required, and since bolt holes need to be drilled, manufacturing and assembly are troublesome, and manufacturing costs are high. However, there is a drawback in that opening and closing the upper lid takes time. Further, since the bolts are fastened with several bolts, there is a possibility that there will be a positional difference in airtightness.

It consists of a spacer, the opening of the valve box has an elliptical shape, the periphery of the opening has an inner collar shape, the upper lid has an elliptical outer collar at the lower end, and the upper lid has a valve with its lower end portion. Insert it into the box so that the outer collar of the upper lid is internally joined to the inner collar of the valve box.Furthermore, the upper lid and the lower part of the packing box are screwed together and can be tightened to the upper part of the packing box. A spacer is interposed between the holding lid screwed to the and the collar in the valve box.

る。In the soft seal sluice valve of the present invention, when the valve shaft is rotated, the valve body screwed with the valve shaft moves up and down in the valve box to open and close the flowing water channel. The upper lid and the packing box are screwed together, and the packing box and the pressing lid are screwed together.
Further, a spacer is interposed between the presser lid and the inner collar of the valve box. Therefore, when the presser lid is rotated and tightened, the space between the presser lid and the inner flange of the valve box is regulated by the spacer, so that the packing box or the upper lid moves upward as the presser lid rotates. become. Then, the outer flange of the upper lid comes into close contact with the inner flange of the valve box opening portion, and the opening portion is shielded in a water leakage preventing state.

全周に亙って常に均等になる。Due to the internal water pressure of the sluice valve, a large pressure acts on the upper lid, but this force acts outward and acts to increase the degree of adhesion between the inner and outer collars, resulting in an airtightness due to an increase in the internal pressure. It has the function of increasing sex. Therefore, a large force is not required for joining the inner and outer flanges, the upper lid can be sufficiently supported only by the screwing force of the pressing lid, and it is not necessary to fasten the both with separate bolts or the like. Furthermore, the degree of adhesion between the inner and outer collars is always uniform over the entire circumference.

A spacer 10 is interposed between the pressing lid 9 and the inner collar 5 of the valve box 1. The spacer 10 has two legs, and the lower ends of the legs press the upper surface of the inner collar 5. Due to the presence of the spacer 10, the presser lid 9 and the inner collar 5 are
Since the interval between the holding cover 9 and the packing lid 9 is tightened, the packing box screwed with the pressing lid 9 or the upper lid 6 screwed with the packing box 9 is pulled up, and the inner collar 5 and the outer collar 7 are Comes into close contact with the sealing material, and the water leakage is prevented.
