Description

[Detailed description of the invention] [Field of industrial application] This invention is designed to fill the operating space above the water stop valve in cold regions to prevent the water stop valve from freezing and dirt from falling into the water stop valve. Regarding a heat-insulating dust-proof plug for water stop valves.

[Conventional technology]

Conventionally, in cold regions, if the operating space located above the water stop valve is left as is, the temperature of the outside air is transmitted to the water stop valve through this space, freezing the inside of the water stop valve and turning the water stop valve off when necessary. This may cause the water stop valve to become inoperable or damage the water stop valve. In order to prevent this, methods such as filling the operating space above the water stopcock with cloth are adopted, but this cloth absorbs moisture and causes problems such as further freezing. The condition was not sufficient to block the influence of outside air on the stop valve. The purpose of this invention is to create an insulating stopper to prevent conventional water stopcocks from freezing in cold regions, as well as to prevent dust and dirt from falling into the interior of the stopcock from the outside. .

[Means for solving problems]

In order to achieve the above object of the present invention, the present invention provides a columnar member made of foamed synthetic resin that is installed in an almost dense manner in the operation space above the water stop valve, at the upper end of the columnar member, or at appropriate locations above and below the member, with a diameter larger than that of the member. The gist of the present invention is an insulating and dustproof stopcock for water stopcocks, which is provided with an elastic sealing piece and has a hanging portion at the upper end.

[Effect]

As described above, the heat-insulating dust-proof plug for a water stop valve according to the present invention has a columnar member made of foamed synthetic material installed in the operating space above the water stop valve in a substantially dense manner, and is provided at the upper end or at an appropriate position above and below the member. Since the elastic seal piece, which has a larger diameter than the above member, is in close contact with the side wall of the operating space, it not only prevents outside air from affecting the stop valve, but also prevents dust and dirt from falling into the operating space, especially downward. It also prevents

〔Example〕

The details of the present invention will be explained based on further illustrated embodiments. Fig. 1 is an explanatory cross-sectional view of the state in which the insulating dust-proof plug for water stop valves according to the present invention is used;
is a water pipe, 2 is a water stop valve, and 3 located above is an operation space for operating the water stop valve 2. Usually, this operation space 3 is a cylindrical space. As the water stop valve 2, the inlet water stop valve 2 is set at the appropriate place in the water pipe introduced from the main pipe to each home.
Although this operating space 3 is a shallow housing-like space with a rectangular plane, the heat insulating dustproof plug 4 according to the present invention can also be used for the water stop valve 2 illustrated in FIG. It can be applied in various ways. That is, the heat-insulating dust-proof stopper 4 shown in the figure is a columnar member made of foamed synthetic resin shown as 5 in the figure, such as a columnar member made of foamed polystyrene, foamed polypropylene, foamed polyurethane, etc. The columnar member 5 made of rubber is attached to the upper end of the columnar member 5 which is in a substantially dense state in the operating space 3 provided in the operating space 3, that is, the diameter is approximately equal to or slightly larger than the diameter of the operating space 3.
A seal piece 6 having a diameter larger than the outer diameter of the columnar member 5 and the seal piece 6 is fixed, a bolt 7 is provided passing through the columnar member 5 and the seal piece 6, a ring as a hanging part 8 is fixed to the upper end, and a set screw at the tip is fixed. 9, they are integrally fixed to each other. The overall view is shown in FIG. 2, and by inserting this stopper 4 into the operation space 3 above the stopcock 2 as shown in FIG. The insulation property prevents cold outside air in cold regions from moving through the operating space 3 and affecting the water shutoff valve 2, and the movement of this cold air is prevented by the foamed synthetic resin columnar member 5 as well as by the elastic It is also tightly blocked by the seal piece 6. Furthermore, the use of the elastic seal piece 6 prevents dust, dirt, etc. from falling from above the operating space 3 into the space 3, particularly toward the water stop valve 2. In another embodiment shown in FIG. 3, the foamed synthetic resin columnar member 5
An embodiment is shown in which a recess 10 is formed on the lower surface of the water stop valve 2 to cover the upper part of the water stop valve 2. By using the stopcock 4 of the second embodiment, the upper part of the stopcock 2 is insulated while being held inside the foamed synthetic resin columnar member 5, and is protected against the effects of cold outside air and cold air from underground. It can be set to a state where it is not affected.

[Effect of idea]

As described above, the heat-insulating dust-proof plug for a water stop valve according to the present invention is installed at appropriate locations above and below the upper end or part of a columnar member made of foamed synthetic resin that is installed in a substantially dense manner in the operating space above the water stop valve. The valve is also provided with a large-diameter elastic seal piece, and a hanging part is provided at the upper end, so when the stopper is inserted into the operation space, the columnar member and the elastic seal piece will prevent outside air from flowing in the direction of the stop valve. In addition to preventing the influence, it is also possible to prevent dust, rubber, etc. from falling into the operating space.
