Introduction:
Technological progress: With the rapid development of artificial intelligence, machine learning, Internet of Things and other technologies, sweeping robots are gradually transforming from simple cleaning tools to intelligent home assistants. In the future, sweeping robots will more accurately identify the environment, more intelligently plan cleaning routes, and even automatically adjust cleaning methods according to users’ living habits.
1、The role of check valves in sweeper
The role of the check valve in the sweeping robot is mainly to control the flow direction of the fluid to ensure that the fluid can only flow in one direction, but not in the opposite direction. The following is the specific role of the check valve in the sweeping robot.
<1>Prevent sewage backfilling: Installing a check valve on the sewage pipe of the sweeping robot can effectively prevent the sewage generated by other equipment from backfilling the sweeping machine, and protect the internal circuit and mechanical structure of the sweeping machine from damage.
<2>Drainage control: The check valve can control the drainage process of the sweeping robot to ensure that backflow does not occur during drainage and keep the drainage system unimpeded.
<3>Maintain system pressure: In the hydraulic system of the sweeping robot, the check valve can maintain the pressure of the system, prevent the pressure from being too high or too low, and ensure the normal work of the sweeping machine.
<4>Maintain system pressure: In the hydraulic system of the sweeping robot, the check valve can maintain the pressure of the system, prevent the pressure from being too high or too low, and ensure the normal work of the sweeping machine.
<5>Improved safety: By preventing fluid backflow, the check valve improves the safety of the vacuum sweeping robot, avoiding failures and accidents that may be caused by fluid backflow.
Refer to above, the check valve plays an important role in the sweeping robot, which improves the performance and safety of the sweeping robot by controlling the flow direction of the fluid.
2、The basic principle of vacuum cleaner check valve
The working principle of the check valve is based on the action of fluid pressure and the mechanical design of the valve. The following are the detailed steps of how the check valve works:
Forward flow: When the fluid flows in from the inlet, it exerts a certain pressure on the disc. This pressure overcomes the action of the spring and opens the valve. Fluid can pass freely through the valve seat while the valve opened.
Reverse flow: When the fluid tries to reverse flow from the outlet back to the inlet, the flow of the fluid will close the disc. The pressure of the fluid pushes the disc against the seat, preventing the fluid from continuing to reverse. The sealing contact of the seat and disc effectively prevents reverse flow.
3、How to choose the right check valve
Selecting the right check valve for your oxygen generator requires consideration of several key factors:
Applicable Pressure Range: The pressure range that the check valve can withstand is the primary consideration in selection. Generally speaking, the wider the pressure range, the better the performance of the valve.
Applicable temperature range: according to the actual working environment to choose the appropriate temperature range of the valve, to ensure that the check valve in a variety of temperatures can work properly.
Fluid characteristics: fluid characteristics such as viscosity, cleanliness, corrosivity, etc. is also an important factor in the selection of valves. For oxygen generators, the cleanliness and corrosiveness of the fluid is particularly important.
Material: Choose the right material to ensure that the check valve can withstand the pressure and temperature changes when the oxygen generator is working, and at the same time has good corrosion resistance.
Reliability: Ensure it has good reliability and durability
4、What are the appropriate check valves of JT Seiko
To choose our check valve, we have a few suggestions: to consider the flow requirements; pressure loss, suction resistance should be low; the noise can not be too big, need to do noise test.
According to the current customer selection, we have the following choices：
High flow diaphragm: low opening pressure, ≤0.2KPA; high flow; reverse 3 kPa without backflow (CJT056).
l Silent check valve: effectively reduce high-frequency noise, can’t do completely noiseless yet; sometimes there will be low-frequency noise, depending on customer trade-offs (CJT220).
l small flow diaphragm valve: can be recommended for customers with high reverse backflow requirements; no backflow in reverse 2 kPa (CJT215,CJT224,CJT221,CJT222).
l Medical Valve Series: CJT153 Suitable for users with small installation space.
Summary:
Jingteng Seiko has a 100,000 grade dust-free workshop and assembly workshop, automated moulding and assembling equipment, and experienced practitioners, which provide a good production environment and hardware guarantee for products with high precision and cleanliness requirements.
