Product Description

Product Introduction

Its shapes are various, such as round, square, water drop, etc., and its interior is hollow to ensure buoyancy. Some models will design reinforcing ribs, connecting interfaces (such as threads, buckles, connecting rod holes) or built-in counterweights according to requirements to adapt to the liquid level control requirements of different scenes.

Product Advantage

Stable material and outstanding chemical resistance.
PVDF is an inert plastic with excellent acid and alkali resistance. It has no reaction to common media such as water, alcohol, detergent and fertilizer solution, and is not easy to be corroded or dissolved. It is suitable for use in scenes containing weakly corrosive liquids such as agriculture and light industry, and there is no risk of heavy metal precipitation, which meets the food contact safety standards.
Good temperature resistance and wide application range.
It can keep stable performance in the temperature range of-20℃ to 80℃, and it can not only adapt to the outdoor low temperature environment in winter, but also tolerate moderate temperature liquids such as domestic hot water and industrial circulating water, which is not easy to deform at high temperature and has a longer service life.
Lightweight texture and balanced strength.
The density is much lower than that of water, the buoyancy is sufficient and the weight is light, and the load-bearing requirements for equipment are low during installation; At the same time, it has a certain impact resistance, and it is not easy to crack due to collision and extrusion at room temperature, which is suitable for scenes with frequent operation or slight vibration.
Controllable cost and simple maintenance.
The price of PVDF raw materials is close to the people, the production process is mature, and the product cost is lower than that of stainless steel or engineering plastic floating balls; The surface is smooth and not easy to scale, and the daily maintenance only needs to be washed regularly to remove impurities. If there is non-fatal damage, it can be repaired by PP special glue, and the comprehensive use cost is low.

Product Operate Guide

Preparation before installation
Environmental assessment: Understand the liquid properties of the use environment in detail to ensure that it is consistent with the application scope of PVDF plastic floating ball. At the same time, measure the size of the liquid storage container, determine the highest and lowest positions of the liquid level, and determine the installation height and connection mode of the floating ball accordingly.
Product inspection: carefully check the appearance of the floating ball to see if there is any damage problem. Manually test the flexibility of the connection parts to ensure that the floating ball can float freely without external force and the internal structure is free from jamming.
Installation process
Threaded connection and installation: If the floating ball is equipped with a threaded interface, align it with the threaded interface reserved by the equipment, and slowly tighten it clockwise. Pay attention to winding a raw material belt or installing a sealing gasket at the interface to prevent liquid leakage. After installation, ensure that the floating ball can freely rise and fall in the direction of liquid level change without being hindered by surrounding components.
Connecting and installing the connecting rod: pass one end of the connecting rod through the connecting hole or clamping groove of the floating ball and firmly fix it with screws, buckles and other accessories. Then connect the other end of the connecting rod with the corresponding mounting bracket on the equipment, and adjust the length of the connecting rod so that the liquid level control device can be triggered to open when the floating ball is at the lowest liquid level; When the floating ball rises to the highest liquid level, the control device closes accurately. During installation, ensure that the connecting rod is vertical and free to move.

Product Uses

Civil life:
Household water tank and solar water heater: the floating ball is linked with the valve. When the water level reaches the set height, the floating ball drives the valve to close and stop the water inflow; When the water level drops, the valve is reopened to replenish water to avoid water overflow or dry burning.
Toilet water tank: the float ball controls the water inlet valve. When the water level in the water tank is low, the water inlet valve will be closed after the water level reaches the preset position, so as to ensure that the water tank can be automatically filled with appropriate water after flushing.
Industrial production:
All kinds of liquid storage tanks: the floating ball level gauge can monitor the liquid level in the tank in real time and transmit it to the control system through mechanical or electronic signals, and give an alarm when the liquid level is too high or too low to ensure production safety.
Sewage treatment: In the sedimentation tank, regulating tank and other facilities, the floating ball is used to monitor the liquid level and control the start and stop of the drainage pump to ensure the stable operation of the sewage treatment process.
