Application of Check Valves on Sweepers

Sweeper is a household appliance that can sweep the floor automatically, which can replace manual floor sweeping work. Usually the sweeper will move and clean the dust, sand and other debris on the floor by itself. Sweepers are suitable for a variety of floor materials such as carpets, wooden floors, tiles and so on. When choosing a sweeper, you need to consider various factors such as the place of use, sweeping effect, noise and so on. By choosing the right sweeper, you can make your home environment cleaner and tidier.

what is the working principle of the check valve?

The working principle of one-way valve is to use fluid pressure and the gravity of the valve disc to control the opening and closing of the valve. When the fluid flows in from the inlet end, the fluid pressure acts on the side of the valve disc, pushing the disc downwards, so that the disc is pressed against the valve seat, thus preventing the fluid from flowing backwards. When the fluid stops flowing in, the disc will return to its initial position by gravity, closing the valve.

The role of the check valve in the sweeper

Check valves play a key role in sweepers, ensuring the normal operation of the machine and the user’s experience.

Prevent dust leakage: One of the roles of the check valve in the sweeper is to prevent dust leakage during the dust collection process. When the sweeper is working, the check valve ensures that no dust is exposed, and when collecting dust, the check valve will be fully open and fit perfectly with the air path of the dust collector, thus preventing the dust from leaking out.

Regulating air pressure: The check valve also regulates the air pressure in the sweeper’s water tank. In sweepers with improved tank construction, the check valve is used to allow the pressure-driven medium to flow in the direction of the pressure-conducting path, but not in the opposite direction, thus regulating the level of air pressure in the water reservoir.

Prevents backflow of liquids: check valves are usually fitted to sewage discharge pipes to prevent sewage from flowing back into the machine when the sweeper stops working. Ensure the normal operation and stability of the system.

The specific application of the water inlet valve in the sweeper

When sweepers are being cleaned or transported, they may sometimes encounter water ingress. If no measures are taken, water ingress may cause serious damage to the structure, electrical and control system of the sweeper. Therefore, we need to choose the right waterproof valve to protect the sweeper in case of water ingress.

The core element of choosing a water inlet valve for sweepers is that the reverse closure should be good, and after filling with water, it cannot leak away from the base station.

Our company’s diaphragm valve assembly is a good choice, anti-reverse flow valve can prevent the fluid reverse flow, by controlling the flow of fluid to ensure that the inlet is tightly closed, so as to play the role of water proof.

The specific application of the replenishment valve in the sweeper

The main purpose of the refill cleaning fluid check valve on a sweeper is to prevent fluid backflow and ensure that the cleaning fluid can be refilled into the tank without any problems. Attach a hose to the Bulkhead fitting, then a short hose on the inside, and then add a check valve to avoid liquid backflow.

This will prevent the cleaning fluid from flowing back during the automatic water up and down process, resulting in an inadequate refill.

When choosing a check valve, it is important to give full consideration to the material resistance, and to choose a suitable check valve according to the PH value of the cleaning liquid.

Suitable check valves can be our specification products, or can be customized according to customers’ requirements.

The specific application of the sewage valve on the sweeper

When the sweeper is working, the sewage will flow through the pipe to the check valve.

Due to the design of the check valve, the sewage can be smoothly discharged from the sweeper through the valve. However, when the sweeper stops working or backs up, due to the unidirectional flow characteristics of the check valve, sewage cannot flow back into the machine, thus avoiding the problem of sewage back-up.

The core if the choice of sewage valve is low pressure to open, duckbill valve is large, to pass through the flow of large, will carry particles.

Add a coarse filter in the front section of the drain valve to filter out fibres and large particles.
