Description
本創作為一種止水閥,尤指一種透過內腔壓力改變而影響進水及出水的止水閥結構。This invention is a water stop valve, especially a water stop valve structure that affects water inlet and outlet through changes in internal cavity pressure.
習用應用於水塔的止水閥係透過槓桿原理及浮力原理調整閥門的啟閉。當水位上升時,透過水的浮力讓浮球向上浮起,同時浮球會帶動連桿位移,而連桿所形成的長力臂與浮球的浮力係會形成較大的力量將止水閥的閥門關閉;當水位下降時,浮球向下並帶動連桿位移,此時止水閥的閥門開啟,水流可以流入水塔內。The water stop valve commonly used in water towers adjusts the opening and closing of the valve through the lever principle and the buoyancy principle. When the water level rises, the buoyancy of the water causes the float ball to float upward. At the same time, the float ball will drive the connecting rod to move. The long moment arm formed by the connecting rod and the buoyancy system of the float ball will form a greater force to move the water stop valve. The valve closes; when the water level drops, the float moves downward and drives the connecting rod to move. At this time, the valve of the water stop valve opens, and the water can flow into the water tower.
然而習用的止水閥受限於連桿的力壁長度,故止水閥整體體積較大,且可能因為結構磨損、鬆動等問題,而導致閥門無法正常啟閉,因此習用的止水閥仍有改善空間。However, the conventional water stop valve is limited by the force wall length of the connecting rod, so the overall volume of the water stop valve is large, and the valve may not be able to open and close normally due to structural wear, looseness, etc., so the conventional water stop valve is still There is room for improvement.
為解決上述課題,本創作提供一種止水閥結構,係透過水位不同而產生的水壓變化,使止水閥結構產生進水或止水之功效。In order to solve the above-mentioned problems, this invention provides a water stop valve structure, which uses water pressure changes caused by different water levels to allow the water stop valve structure to have the effect of water inlet or water stop.
為達到上述目的,本創作提供一種止水閥結構,包含一閥座、一外殼及一止水閥組。In order to achieve the above purpose, this invention provides a water stop valve structure, which includes a valve seat, a shell and a water stop valve group.
閥座包含一閥體、一進水道、一出水道、一進水孔及一出水孔,閥體內部係形成一閥室,閥體外壁面分別設置進水道及出水道,閥體內壁面分別設置進水孔及出水孔,進水道連通進水孔,出水道連通出水孔,出水孔與進水孔係分別連通閥室。The valve seat includes a valve body, a water inlet, a water outlet, a water inlet and a water outlet. The interior of the valve body forms a valve chamber. The outer wall of the valve is provided with an inlet and a water outlet respectively. The inner wall of the valve is provided with an inlet and outlet. The water hole and the water outlet hole, the water inlet channel is connected to the water inlet hole, the water outlet channel is connected to the water outlet hole, and the water outlet hole and the water inlet hole are connected to the valve chamber respectively.
外殼的壁面貫設至少一通孔,外殼於一端壁面延伸一結合段,結合段係將外殼的一端壁面分隔為一內環壁及一外環壁,結合段結合閥體,使閥體的一端壓抵於外環壁,內環壁係位於閥室的範圍內,內環壁貫設一洩壓孔,洩壓孔連通閥室,外殼內部形成一容置空間,容置空間連通通孔,容置空間內部設置一壓抵結構及一浮體,壓抵結構具有一壓抵部,壓抵部係可往復位移壓抵於洩壓孔。At least one through hole runs through the wall of the housing, and a coupling section extends from one end wall of the housing. The coupling section divides one end wall of the housing into an inner ring wall and an outer ring wall. The coupling section is combined with the valve body to press one end of the valve body. Against the outer ring wall, the inner ring wall is located within the scope of the valve chamber. A pressure relief hole is installed through the inner ring wall, and the pressure relief hole is connected to the valve chamber. An accommodation space is formed inside the shell, and the accommodation space is connected to the through hole. A pressing structure and a floating body are provided inside the placement space. The pressing structure has a pressing portion, and the pressing portion can move back and forth to press against the pressure relief hole.
止水閥組包含一閥片、一止水墊片及一彈性件,閥片緊配結合止水墊片,止水閥組設置於閥室,且彈性件係位於閥片與內環壁之間,使止水墊片可往復位移於閥室,用以同時封閉或開啟出水孔及進水孔。The water stop valve group includes a valve disc, a water stop gasket and an elastic member. The valve disc is tightly coupled with the water stop gasket. The water stop valve group is arranged in the valve chamber, and the elastic member is located between the valve disc and the inner ring wall. time, so that the water-stop gasket can move back and forth in the valve chamber to close or open the water outlet and water inlet at the same time.
藉由上述結構,當水位沒有滿的時候,洩壓孔沒有被壓抵結構堵住,因此閥室的壓力會低於進水道的壓力,進水道的水流會將止水閥組向下推壓,水流將會經由進水孔流經出水孔,接著再順著出水孔流往出水道,即可達到補水之目的。With the above structure, when the water level is not full, the pressure relief hole is not blocked by the pressure structure, so the pressure in the valve chamber will be lower than the pressure in the water inlet, and the water flow in the water inlet will push the water stop valve group downward. , the water will flow through the water inlet hole, through the water outlet hole, and then flow along the water outlet hole to the water outlet, thus achieving the purpose of replenishing water.
當水位滿的時候,水會經由通孔流往外殼的容置空間並推抵浮體向上,當浮體向上位移時會施力於壓抵結構,進而使壓抵部堵住洩壓孔。當洩壓孔被堵住後,閥室的壓力會逐步上升直至閥室的壓力與進水道的壓力相當為止。由於出水道係連通大氣,故其壓力幾乎是零,因此根據流體係沿著高壓至低壓(負壓力梯度)方向運動的原理,止水閥組會因為負壓而向上位移並同時貼抵出水孔及進水孔,使水流無法再流經進水孔或出水孔,藉此達到止水之目的。When the water level is full, water will flow into the housing space of the shell through the through hole and push the floating body upward. When the floating body moves upward, it will exert force on the pressing structure, causing the pressing portion to block the pressure relief hole. When the pressure relief hole is blocked, the pressure in the valve chamber will gradually increase until the pressure in the valve chamber is equal to the pressure in the water inlet. Since the water outlet system is connected to the atmosphere, its pressure is almost zero. Therefore, based on the principle that the fluid system moves in the direction from high pressure to low pressure (negative pressure gradient), the water stop valve group will be displaced upward due to the negative pressure and at the same time close to the water outlet hole. And the water inlet hole, so that the water can no longer flow through the water inlet hole or the water outlet hole, thereby achieving the purpose of stopping water.
