ブに関する。[Detailed description of the invention] [Industrial application field] The present invention forms an annular water outlet on the periphery of a valve body, and a cylindrical valve body for opening and closing the water outlet is fitted onto the valve body, The present invention relates to a fixed cone valve in which the operating device for the cylindrical valve body is arranged near the outside of the valve body.
従来、上記フイツクスドコーンバルブでは、操
作装置及び筒状弁体が外方に露出していた。
Conventionally, in the above fixed cone valve, the operating device and the cylindrical valve body have been exposed to the outside.
しかし、弁本体の環状放水口からは、放水時に
非常に多くの水滴が弁本体の周部に飛びちり、寒
冷地又は寒冷期では、その水滴が筒状弁体の操作
装置や、弁本体と筒状弁体との間の摺動部に付着

閉操作ができなくなる虞れがあつた。
However, when water is discharged from the annular water outlet of the valve body, a large number of water droplets fly around the valve body, and in cold regions or during cold seasons, the water droplets may come into contact with the operating device of the cylindrical valve body or the valve body. It could adhere to the sliding part between it and the cylindrical valve body and freeze, which could make it impossible to open and close the water outlet.
本考案の目的は、操作装置及び弁本体と筒状弁
体との摺動部が、水滴の付着によつて凍結しない
ようにする点にある。 An object of the present invention is to prevent the operating device and the sliding portion between the valve body and the cylindrical valve body from freezing due to adhesion of water droplets.

その作用効果は、次の通りである。
The fixed cone valve of the present invention is characterized in that a fixed waterproof cover for the operating device is attached to the valve body, a movable waterproof cover covering the outside of the cylindrical valve body is attached, and the fixed cone valve is movable with respect to the fixed waterproof cover. The waterproof cover is slidably and watertightly fitted inside the fixed waterproof cover, and a freeze prevention heater is disposed inside each of the fixed and movable waterproof covers,
Its effects are as follows.
つまり、筒状弁体の操作装置、及び、筒状弁体
は、夫々、固定防水カバーや可動防水カバーで覆
われ、固定防水カバーに対して可動防水カバーを
摺動自在に、かつ、水密状に内嵌させてあるため

水滴が凍結することがない。
In other words, the operating device for the cylindrical valve body and the cylindrical valve body are covered with a fixed waterproof cover and a movable waterproof cover, respectively, so that the movable waterproof cover can slide freely relative to the fixed waterproof cover and be watertight. Since the cover is fitted inside the cover, water droplets splashed from the water outlet not only do not adhere to the cylindrical valve body or its operating device, but also prevent it from entering into both covers. Even if water droplets adhere to the movable waterproof cover, the adhering water droplets will not freeze due to the antifreeze motor placed inside the cover.
また、万一両防水カバーの内部に水が浸入して
も、凍結防止用ヒータによつて、水が凍結するこ
とがない。 Furthermore, even if water should infiltrate the interior of both waterproof covers, the antifreeze heater will prevent the water from freezing.
従つて、寒冷地や寒冷期においても、固定防水

放水量の調節を、環境温度の悪影響を受けずに良
好にできるようになつた。
Therefore, even in cold regions and periods, the movable waterproof cover can maintain smooth sliding operation relative to the fixed waterproof cover, and the amount of water discharged from the fixed cone valve can be adjusted well without being adversely affected by the environmental temperature. Now I can do it.
