The function of lift check valves

The function of the lift check valve is to let the fluid flow in one direction to prevent it from flowing backward. The check valve is used in the hydraulic system to prevent oil from flowing in the opposite direction.

The function of lift check valves

1. Check valve, also known as a check valve or check valve, is a kind of valve that can make the fluid flow in only one direction without reverse flow. If the check valve is used in the hydraulic system, it can avoid oil flowing in the opposite direction. If the check valve is used in the pneumatic system, it can avoid the reverse flow of compressed air.

2. If it is a common check valve, it has only one function, that is, to make the oil flow in one direction only, not in the opposite direction. If the check valve is installed at the outlet of the pump, it can avoid damage to the oil pump and play a checking role when the pressure in the system suddenly increases.

3. When the pump is not working, the check valve can also prevent the oil in the system from flowing back to the tank. The check valve can also play the role of separating the oil circuit and avoiding mutual interference between the oil circuits. When the check valve is combined with other valves, it can be combined into a composite valve.

4. If the check valve and throttle valve or pressure-reducing valve are connected in parallel, the actuator can be formed, so that the fluid can flow slowly in the forward direction and rapidly in the reverse direction. Or it can slow down the flow in the forward direction, and conduct a free-flow circuit in the reverse direction.

5. If the check valve and pressure valve are connected in series, the pressure can be slowly increased, and adjusted to avoid pressure reaction. If the check valve is classified according to its structure, it can generally be divided into three types: lift check valve, swing check valve and butterfly check valve. The function of the check valve will vary with the structure, so you should select the appropriate check valve according to the installation environment and your own needs.

Correct installation method of water pipe lift check valves

1. First of all, when we get the product, we should first understand the function of each part and part of the product, and then assemble it according to the effective product drawing, without applying glue, to see whether the assembly is correct. If it is correct, then we should start the installation process of the check valve.

2. Before installation, we need to confirm the installation space. After confirmation, we need to make room for the installation of the check valve.

3. Then we put the check valve into the space we separated and began to install it with glue. When placing it, we should pay attention to the horizontal installation, and not tilt it. When installing, we must make sure that the arrow side of the check valve is upward, otherwise the water may flow backward.
