產品描述 Product Description

進口隔膜式水力遙控浮球閥主要安裝工況企業、民用建筑等領域的各種水池、水塔進水口處，當水池達到預設定水位時，浮球導閥控制主閥自動關閉，進水口停止供水；水位下降時，閥門自動開啟補水The imported diaphragm type hydraulic remote control floating ball valve is mainly installed at the inlet of various water tanks and towers in industries such as enterprises and civil buildings. When the water tank reaches the pre-set water level, the floating ball guide valve controls the main valve to automatically close, and the water supply at the inlet stops; When the water level drops, the valve automatically opens to replenish water

其特點如下：Its characteristics are as follows

1、關閉嚴密可靠。采用襯膠閥瓣密封，利用液壓控制原理，使閥瓣關閉力成正比，密封可靠性高 Close tightly and reliably. Adopting rubber lined valve disc sealing, utilizing hydraulic control principle to make the valve disc closing force proportional, with high sealing reliability

2、過流量大。采用半直線型流道寬閥體和等過流量面積設計，閥門阻力小 Excessive flow. Adopting a semi linear flow channel with wide valve body and equal flow area design, the valve has low resistance

3、運行安全，關閉速度可調，閥門動作平穩，啟閉不產生壓力波動，無管振和噪音 Safe operation, adjustable closing speed, stable valve action, no pressure fluctuations during opening and closing, no pipe vibration or noise

4、使用維護方便。主閥體可安裝在水池外面，調試檢查方便，維護簡單 Easy to use and maintain. The main valve body can be installed outside the water tank, making debugging and inspection convenient and maintenance simple

工作原理 working principle

主閥安裝在水池外，浮球導閥安裝在水箱內，當水位降低時，浮球導閥打開，閥蓋的控制室壓力卸掉，則主閥開啟向水池供水：當水位上升時，浮球導閥關閉，閥蓋的控制室壓力增加，則主閥關閉停止向水池供水。

The main valve is installed outside the water tank, and the floating ball guide valve is installed inside the water tank. When the water level drops, the floating ball guide valve opens, and the control room pressure of the valve cover is relieved. The main valve opens to supply water to the water tank. When the water level rises, the floating ball guide valve closes, and the control room pressure of the valve cover increases. The main valve closes to stop supplying water to the water tank.

全開狀態 Fully open state

當水泵啟動后，閥門進水口壓力上升，壓力水一方面推動主閥板開啟，另一方面通過導管系統進入膜片（活塞）下腔，而膜片（活塞）上腔的水通過導管系統泄入壓力低的閥門出水口，而閥門在二合力的作用下緩慢開啟。

After the water pump starts, the pressure at the valve inlet rises. On the one hand, the pressure water pushes the main valve plate open, and on the other hand, it enters the lower chamber of the diaphragm (piston) through the conduit system. The water in the upper chamber of the diaphragm (piston) is discharged into the outlet of the low pressure valve through the conduit system, and the valve slowly opens under the combined force of the two forces

全閉狀態 Fully closed state

當水泵停機后，閥門中的水流速度降低，在接于近零時，主閥板在彈簧力和自身重力作用下快速關閉，而閥后的壓力水通過導管系統返回膜片（活塞）上腔，并推動固定閥桿上的小閥板緩慢關閉。

After the water pump stops, the water flow velocity in the valve decreases. When it is close to zero, the main valve plate quickly closes under the action of spring force and self gravity, while the pressure water behind the valve returns to the upper chamber of the diaphragm (piston) through the conduit system and pushes the small valve plate on the fixed valve rod to slowly close.

結構和主要零件材質 Structure and main component materials

隔膜式水力遙控浮球閥分二種型式： 膜片式與活塞式。結構由主閥、過濾器、針閥、球閥和浮球導管等組成。由于浮球導閥、針閥和球閥等是用外接導管與主閥相連接，所以統稱為導管控制系統

There are two types of diaphragm type hydraulic remote control floating ball valves: diaphragm type and piston type. The structure consists of a main valve, a filter, a needle valve, a ball valve, and a float tube. Due to the use of external conduits to connect floating ball guide valves, needle valves, and ball valves to the main valve, they are collectively referred to as conduit control systems

1.為了更有效地防止水錘的產生，水力控制閥將控制室設計成雙腔體形式。根據不同的用途可以將兩個腔室彼此隔離或相通，以實現緩開、緩閉或速閉等輔助功能。在一定程度上阻礙水錘的產生或功緩解水錘的力度，保護閥后的其他設備不受損壞。除此之外，閥蓋與上腔室連為一體，使得閥蓋、上腔室、閥桿、閥盤成為整體，只要松開閥體上的連接螺栓，即可將其一并取出，方便維修及更換易損件。

In order to more effectively prevent the generation of water hammer, the hydraulic control valve designs the control room in a dual chamber form. According to different purposes, two chambers can be isolated or connected to each other to achieve auxiliary functions such as slow opening, slow closing, or quick closing. To some extent, it hinders the generation of water hammer or alleviates the force of water hammer, protecting other equipment behind the valve from damage. In addition, the valve cover is connected to the upper chamber as a whole, making the valve cover, upper chamber, valve stem, and valve disc a whole. As long as the connecting bolts on the valve body are loosened, they can be taken out together for easy maintenance and replacement of vulnerable parts.

2.隔膜式水力控制閥閥桿兩頭導向的結構，采用中段長節距導向，避免了閥蓋和閥座上的導向孔因加工或安裝不同心，導致閥桿運動受阻、易卡死現象，中段導向套與上閥體整體澆鑄，加工精度得到保證，同時在與閥桿的接觸面間加一銅質襯套，保護閥桿表面不被磨損、擦毛，使閥桿運動自如、平穩、靈活。

The structure of the diaphragm type hydraulic control valve stem is guided at both ends, adopting a mid section long pitch guidance, which avoids the phenomenon of the valve stem movement being blocked and easily stuck due to uneven machining or installation of the guide holes on the valve cover and valve seat. The mid section guide sleeve and upper valve body are cast as a whole, ensuring machining accuracy. At the same time, a copper sleeve is added between the contact surface with the valve stem to protect the surface of the valve stem from wear and burrs, making the valve stem move freely and smoothly flexible

3.隔膜式水力控制閥的閥蓋、上腔室、閥桿、閥盤可整體取出，方便維修及更換橡膠密封面、O形環等易損件。閥蓋與上腔室之間的隔膜采用尼龍網布加強型橡膠隔膜，耐剪切應力使用安全可靠。內件包括上腔式、閥桿、閥盤、彈簧、螺栓等，除了不銹鋼件以外都進行了無毒噴塑處理，具有良好的防腐性能。

The valve cover, upper chamber, valve stem, and valve disc of the diaphragm hydraulic control valve can be taken out as a whole, making it convenient for maintenance and replacement of vulnerable parts such as rubber sealing surfaces and O-rings. The diaphragm between the valve cover and the upper chamber is made of nylon mesh reinforced rubber diaphragm, which is safe and reliable for shear stress resistance. The internal components, including the upper chamber, valve stem, valve disc, spring, bolt, etc., have undergone non-toxic spray molding treatment except for stainless steel parts, which has good anti-corrosion performance.

4.隔膜式水力控制閥的閥盤采用間隙組合結構，即閥桿和閥盤孔之間有一定的間隙；閥盤用螺釘和擋塊相對固定在閥桿之間并留有1-2毫米間隙，這樣閥盤在垂直于閥桿的平面上有一定的自由度，可以彌補由于加工或裝配誤差造成閥座密封面與閥桿不垂直的缺陷，實現了零泄漏

The valve disc of the diaphragm hydraulic control valve adopts a clearance combination structure, that is, there is a certain gap between the valve stem and the valve disc hole; The valve disc is relatively fixed between the valve stem with screws and stop blocks, leaving a gap of 1-2 millimeters. This allows the valve disc to have a certain degree of freedom in the plane perpendicular to the valve stem, which can compensate for the defect of the valve seat sealing surface not being perpendicular to the valve stem due to machining or assembly errors, achieving zero leakage.

安裝與調試

1、主要安裝于水池或高水位水塔的管道上，最佳安裝方式是水平安裝在管線上，閥蓋朝上，其它安裝方式也可達到操作功能。浮球安裝于水池或水塔內，以便遙控。

2、安裝前要清除管內雜物，沖洗管道。安裝時要注意主閥體外水流標示箭頭，要遵循方向安裝。

3、主閥前要裝一直閘閥和一只過濾器，主閥后也要裝一只閘閥，以便于維修。

4、試水時要慢慢開啟主閥前的閘閥，慢慢增加壓力，同時注意閥體外的控制管路是否漏水。關閉球閥14時，主閥應能關閉，如果主閥不能關閉，檢查主閥密封面，可能夾有贓物，將閥蓋和帶膜片閥桿拆卸，清除贓物即可試水。

5、為出廠時包裝方便，浮球閥裝于主閥上。

6、主閥導管進口處的微型過濾器要2-3個月清洗一次
