Application characteristics of Shanghai sword floating ball Industrial Valves valve production application has the following features: use hydraulic design principle of hydraulic design principle can be achieved in a short time, opening and closing action, when the water from the water inlet in, night baffle internal pressure rise, in a timely manner to open the valve cavity, so that the valve is opened, when the water reaches a certain height, floating ball, this time is the lever principle, floating ball continues to rise, float to drive the stem, stem pressure in the fixed foot, foot pedestal withstood the pistons, piston to resist valve cavity, at this time, the valve is closed. Has light structure, opening and closing the reliable design of floating ball valve structure is relatively simple, mainly by the floating ball, valve stem and valve body of three important components, can be installed in the tank, can be installed in the pool, because of its simple design agency, material consumption, the overall float valve is smaller and lighter, the open and closed at the same time also is relatively sensitive, important to be able to block the water, making water not overflow. High sensitivity, small head loss in mechanical manufacturing, with high precision for the first, at the time of production, belongs to the mechanical manufacturing automation, the inside of the component parts have been made in automation equipment, precision production technology, to make it more with a high sensitivity adjustment application, water head loss of pressure is calculated according to the opening of valve in the valve cavity, the pressure loss of the general head are small opening valve cavity, floating ball nature can use a little bit small, we design the floating ball is a big ball float structure, not only to be able to achieve full circulation in the flow, but also can be closed. The advantages of no water hammer valve closing fast, as a result of the pressure flow inertia, produce water shock wave, just like a hammer, so called water hammer. Float valve itself is depend on water to close the main valve, water level is rising slowly, floating ball is also slowly rising, won't appear suddenly shut down and produce water hammer. Has light weight, small size to design for easy installation, select material is stainless steel, but in all activities in the design of the principle to design the material consumption, to ensure that the weight of the floating ball valve itself will not too heavy, affect the installation, at the same time of material consumption must also make the floating ball valve smaller, not because the volume is too big, restricted by space during installation. Installation and maintenance is convenient wait for a characteristic floating ball valve repair, as long as the floating ball, the valve stem is removed, to see if there are any more damage, floating ball in from the valve itself to check the reason, the general floating ball valve, such as using the problems are made by deformation of the seal inside, or cracks caused by water pressure is too large, as long as the replacement seal can be in again to use the line of the installation, is very convenient and quick.
