る。 Hereinafter, one embodiment of the water draining device according to this invention will be explained in detail based on the drawings.
In the figure, A is a bottomed cylindrical drain plug made of synthetic resin or the like with restoring force, and a sealing material such as a sealing O-ring 1 is fitted onto the upper outer periphery of the drain plug, and a lower outer periphery An engaging protrusion 2 is formed on the lower inner periphery, an expanding protrusion 3 is formed on the lower inner periphery, a flange 9 for an operation knob is integrally formed on the lower end, and two or more vertical grooves 4 are formed on the lower periphery. The lower part of the opening can be expanded. B is a short water drain pipe which communicates with a water drain hole 10 bored at the bottom of the diaphragm chamber 5 etc. of the hydraulic response device and has a water drain hole 6 into which the water drain plug A can be inserted and removed; E, and when the drain plug A is inserted into the drain hole 6, the sealing O-ring 1 is fitted while maintaining watertightness, and it can be easily removed and removed. When the lower part of the drain plug body A is expanded, the engagement protrusion 2 is engaged, and when the expansion is released, the engagement groove 7 is disengaged. have. C is a tapered wedge body for expanding the lower part of the drain plug body A, and is integrated with a protrusion 8 having an outer facing distance that is larger than an inner facing distance of the expanding protrusion 3 of the drain plug body A. The lower end is provided with a flange 11 for an operation knob.
上記構成において、ガス湯沸器の使用時は水抜
き短管Bの水抜き孔6は水抜き栓体Aにより閉塞
されている。すなわち、水抜き孔6に水抜き栓体
Aを下方より一定の位置まで挿入すると、その上
方外周部のシール用Oリング1が水抜き孔6に水
密を保つて嵌着されるとともに、下方外周部の係
合凸起2は水抜き短管Bの係合凹溝7と同一位置
に位置する。そこで、この水抜き栓体Aにくさび
体Cを下方から一定の位置まで挿入せしめること
でくさび体Cの突条8に水抜き栓体Aの拡開凸起
3がのり上げてその下方部を押し拡げ係合凸起2
を係合凹溝7に押圧係合し水抜き栓体Aを水抜き
短管Bに抜脱しないよう保持せしめている(第2
図参照)。尚、この際くさび体Cの先端が水抜き
栓体Aの底壁に当接するよう設定するとよい。 In the above configuration, the drain hole 6 of the short drain pipe B is closed by the drain plug A when the gas water heater is in use. That is, when the drain plug A is inserted into the drain hole 6 from below to a certain position, the sealing O-ring 1 on the upper outer periphery is fitted into the drain hole 6 in a watertight manner, and the lower outer periphery The engagement protrusion 2 of the part is located at the same position as the engagement groove 7 of the short water drain pipe B. Therefore, by inserting the wedge body C into the drain plug A from below to a certain position, the expanding protrusion 3 of the drain plug A rides on the protrusion 8 of the wedge body C, and the lower part thereof is lifted up. Push-spread engagement protrusion 2
is press-engaged with the engagement groove 7 to hold the drain plug A so that it does not slip out into the short drain pipe B (the second
(see figure). At this time, it is preferable to set the tip of the wedge body C so that it comes into contact with the bottom wall of the drain plug body A.
次に、ガス湯沸器の使用を停止して水抜きを行
う場合は、まず、操作つまみ用鍔11を握つてく
さび体Cを下方へ引き抜くと、その突条8と拡開
凸起3の当接関係が外れるため突条8による水抜
き栓体Aの拡開は解かれ係合凸起2と係合凹溝7
との押圧係合が外れるからその後水抜き栓体Aを
下方へ引張れば、これが水抜き短管Bの水抜き孔
6から容易に抜脱できる。しかして、水圧応動装
置のダイヤフラム室5等の滞留水は水抜き導孔1
0から水抜き孔6を介して器外へ排水されるので
ある。 Next, when you want to stop using the gas water heater and drain the water, first grasp the operation knob collar 11 and pull out the wedge body C downward, so that the protrusion 8 and the expansion protrusion 3 Since the abutting relationship is removed, the expansion of the drain plug body A by the protrusion 8 is released, and the engagement protrusion 2 and the engagement groove 7 are released.
After that, by pulling the drain plug body A downward, it can be easily removed from the drain hole 6 of the short drain pipe B. Therefore, the accumulated water in the diaphragm chamber 5, etc. of the hydraulic response device is removed from the water drain hole 1.
The water is drained from the container through the drain hole 6.
水抜き完了後、水抜き短管Bに対する水抜き栓
体Aとくさび体Cの組付けは水抜き時とは逆の操
作で簡単に行えること先に説明したとおりであ
る。 After draining the water, as described above, the drain plug body A and the wedge body C can be easily assembled to the short drain pipe B by reversing the operation for draining water.
この考案は以上説明したように、水抜き短管に
対し水抜き栓体とくさび体を挿入、抜脱するだけ
で水抜き孔の開閉が適確に行える構造としたから
ねじ体を使用しないことと相まつてその操作が簡
易で使い勝手がよく、錆や損傷及び水洩れも少な
いので耐久性にもすぐれた水抜き装置が得られる
ものである。 As explained above, this design has a structure in which the drain hole can be opened and closed accurately by simply inserting and removing the drain plug and wedge body into the short drain pipe, so no screw body is used. In combination with this, it is possible to obtain a water draining device that is easy to operate, easy to use, and has excellent durability because it is less prone to rust, damage, and water leakage.
