The remote control float valve and flange gate valve are the same type of valve. The difference is that its closing part is a sphere. The sphere rotates around the center line of the valve body to achieve opening and closing. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Two-piece ball valves and three-piece ball valves are a new type of valve that has been widely used in recent years. This type of valve should generally be installed horizontally in the pipeline.
advantage:
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.
2. Simple structure, small size and light weight.
3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics and has good sealing performance. It has also been widely used in the vacuum system.
4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.
5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.

Remote control float valve can be divided into straight-through type, three-way type and right-angle type according to its channel position. The latter two ball valves are used to distribute the medium and change the flow direction of the medium. The installation and maintenance of three-piece ball valve should pay attention to the following matters:
1. Leave a position for the valve handle to rotate.
Remote control float valve
Remote control float valve (2)
2. Cannot be used for throttling.
3. The ball valve with transmission mechanism should be installed upright.
Second, the working principle of the remote control float valve is to make the valve unblocked or blocked by rotating the valve. The ball valve switch is light, small in size, can be made into a large diameter, reliable in sealing, simple in structure, easy to maintain, the sealing surface and the spherical surface are often in a closed state, and it is not easy to be eroded by the medium. It is widely used in various industries.

7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should show a spherical surface at the entrance and exit, so as to cut off the flow.
Remote control float valve, high platform ball valve is a relatively new type of ball valve, it has some advantages unique to its own structure, such as frictionless switch, non-wearing seal, and small opening and closing torque. This can reduce the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and close shut-off of the medium. It is widely used in petroleum, chemical, urban water supply and drainage and other working conditions that require strict cut-off.
1 In the closed position, the ball is pressed against the valve seat by the mechanical pressure of the valve stem.
2 When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction, and the angular plane at the bottom causes the ball to separate from the valve seat.
3 The valve stem continues to rise, and interacts with the guide pin in the spiral groove of the valve stem, so that the ball begins to rotate without friction.
4 until it reaches the fully open position, the valve stem is raised to the limit position, and the ball rotates to the fully open position.
B, closing process
1 is closed, turn the handwheel clockwise, the valve stem begins to descend and the ball leaves the valve seat and starts to rotate.
2 Continue to rotate the hand wheel, and the valve stem is acted on by the guide pin embedded in the spiral groove on it, so that the valve stem and the ball rotate 90° at the same time.
3 When it is about to close, the ball has rotated 90° without contact with the valve seat.
4 In the last few turns of the handwheel, the angular plane at the bottom of the valve stem mechanically wedges and presses the ball, making it tightly pressed against the valve seat to achieve a complete seal.
The 100X remote control float valve can effectively control the liquid level of the water tower or the water tank, cut off or open the spool when appropriate, or prevent the water flow from leaking out, the liquid level control is accurate, the water level is not interfered by pressure fluctuations, the opening and closing are tight and there is no leakage, and the float is flexible , Simple maintenance. Suitable for automatic water supply system of water tanks, pools and water towers in high-rise buildings
