100X Remote control float valve-China Bohai Valve Group Co., Ltd.
This kind of valve is designed and manufactured by our engineer with reference to the same type products domestic and overseas .Body design adopt to full port streamlined .Small Fluid resistance large flow, good sealing effect .As equipped with a catheter on the main valve,using water power, can control the water tower or liquid surface of pool automatically,easy maintenance,Flexible and durable,high accuracy liquid level control,Water level without hydraulic interference and tight shutoff no leaking,welcome to purchase
II、Structure
The valve consists of the main valve, needle valve, ball valve, floating ball valve and micro filter ,as the figure below :
1、Body 2、Nut 3、Sealing Ring 4、Disc 5、Stem 6、Diaphragm Press Plate 7、Diaphragm
When the pipeline supply water from the inlet of valve, due to the needle valve15, ball valve14, floating ball valve10 is normally open, so the medium through needle valve15 into the bonnet control room, and through the ball valve14 and floating ball valve10 flow into the water tank ,control room can not form pressure, the inlet pressure act below the main plate will lift the main plate to open main valve supply a large number of water, when tank water level is rising, float floating ball after10 seconds floating ball valve is closed, water in bonnet control room will gradually increased pressure value to let the main valve closed, which have played an important role in automatic remote control.
IV、 Installation and adjustment
1.The main valve installed on the the inlet tube of tank or the high water tower,he best installation way of the main valve is horizontal installation, bonnet up, other installation method can reach the use function,
2.thoroughly remove the clutter of pipe before installation . Pay attention to the main valve body outer flow labeled arrows, should follow the direction installation.
3.Before the main valve need to install a gate valve and a filter, after the main valve also need to install a gate valve, in order to maintenance.
4.When testing the waters, need to open the ball valve on the main valve bonnet ,then open the gate valve in front of the main valve,at this moment main valve should supply water to tank normally,closed the ball valve,main valve closed following.If couldn’t close ,There are dirt under the main valve,have a try after removing the dirt.When main valve supplying water ,floating ball pilot valve running water at the same time ,If use hand carry floating ball, floating ball valve closed,The main valve is closed following ,proved floating ball valve is good.
5.Floating ball valve install on the main valve,in order to factory packing convenient, actual installation as shown
6.The micro filter on main valve pipe inlet need to wash a 2-3 times per months
