Install a check valve to ensure the direction of water flow in the pump to ensure proper pump operation. Therefore, regarding the installation position of the check valve, it can be divided into two cases whether it is installed before or after the pump: one is the end of the vertical suction pipe installed in the front of the pump, also known as the bottom valve. The purpose is to fill the pump once without pumping. Because there is no water in the pump and in the suction pipe in front of the pump, the pump can only pump in when it is idling, so the pump must be filled with water to pump water. This The water pump installation is a method when the liquid level is high, also known as the negative pressure method. The other is installed behind the pump. This installation method is performed with the liquid level above the pump, which makes it easy to start and stop the pump without closing the pump outlet valve, especially for mother-controlled pump systems, to prevent backflow. The check valve must be installed at the pump outlet and before the outlet control valve in order to service the check valve. The first outlet of a normal pump is a soft connection (shock absorber), then a check valve, then a globe valve (eg butterfly valve, gate valve, globe valve, etc.).
System safety and efficiency, it’s important to install them correctly. In this article, we’ll discuss the optimal installation position of check valves, as well as why it’s so essential to position them correctly.
First, let’s talk about what check valves are and how they work. Also known as one-way valves, they allow fluid or gas to flow in one direction only. When fluid flows in the desired direction, the valve opens, but if flow tries to reverse, the valve closes automatically, preventing backflow. This ensures that contamination or damage caused by backflow doesn’t occur, preventing costly repairs or even system failure.
One of the most critical aspects of check valve installation is the position in which they are placed. The location and orientation can play a significant role in the efficiency and operation of the valve. Here are some things to consider when choosing the installation position of your check valve:
1. Install check valves in the correct orientation – One of the most common mistakes made during check valve installation is installing them in the wrong orientation. Check valves are designed to allow flow in one direction, so they must be installed with the correct orientation. Installing them backwards can cause major damage to your system, including pressure drops, increased turbulence, and increased wear and tear on the valve.
2. Position the valve close to the pump – Positioning the check valve as close as possible to the pump is critical. Doing so can prevent backflow and ensure that the system operates at maximum efficiency. Additionally, if the valve is placed far from the pump, the fluid may not be able to flow through it, causing unwanted pressure build-up, which can lead to leaks, damage to the pump, and even system failure.
3. Flow direction – It’s important to ensure you choose a check valve that is designed to operate in the desired flow direction. Installing a valve designed for a different flow direction can cause significant issues, including backflow, turbulent flow, and damage to the valve.
4. Correct sizing – Choosing the correct size check valve is also an essential aspect of installation. If the valve is too small, it can impede flow, leading to increased pressure and damage to the valve or even the entire system. On the other hand, a valve that is too large can increase turbulence, causing leaks, and other issues.
