Chinese check valve use method graphic tutorial: How to correctly operate the Chinese check valve
China check valve is a commonly used fluid control equipment, and its correct operation is crucial to ensure the normal operation of the equipment. This article will introduce you how to properly operate the Chinese check valve from a professional perspective, and provide an illustrated tutorial to help you better understand and master the use of the Chinese check valve.
1. Prepare for installation
Before installing the Chinese check valve, the following preparations need to be made:
(1) Confirm the medium and pressure level of the pipeline system, and select the appropriate Chinese check valve type and material.
(2) Check the connection method and size of the pipeline system to ensure that the Chinese check valve can match the pipeline system.
(3) Prepare the necessary tools and materials, such as wrenches, screwdrivers, gaskets, etc.
2. Installation Procedure
(1) Determine the installation location: according to the layout and design requirements of the pipeline system, select the appropriate installation location. In general, the Chinese check valve should be installed at the entrance or exit of the pipeline to control the direction and flow of the fluid.
(2) Mark the installation position: Use a marker pen or other tools to mark the installation position of the China check valve on the pipeline.
(3) Remove the old valve: if other valves have been installed before, they need to be removed first. When using tools such as wrenches to remove old valves, pay attention to safety measures to avoid damaging other components.
(4) Clean the installation surface: clean the oil, dust and other impurities on the installation surface to ensure that the China check valve can work normally.
(5) Install the new valve: Place the new China check valve in the marked position, and use tools such as wrenches to fix it on the pipeline. Note that the direction and position of the valve are correct and that it is tightly connected to the pipe.
(6) Adjust the valve opening: according to the actual situation, adjust the opening of the valve to achieve the desired fluid control effect.
3. Operation precautions
When using Chinese check valves, you also need to pay attention to the following:
(1) Regular inspection and maintenance: regularly check the working status and sealing performance of the China check valve, and replace the damaged parts in time to extend the service life of the equipment.
(2) Prevent reverse flow: In the process of use, special attention should be paid to prevent the occurrence of reverse flow, so as not to affect the normal operation of the China check valve.
(3) Avoid excessive pressure: When using the Chinese check valve, excessive pressure should be avoided to avoid damage to the valve parts.
(4) Pay attention to power wiring: If the China check valve needs a power drive, pay attention to the correct wiring and take the necessary safety measures.
In short, the correct operation of the Chinese check valve is the key to ensure its normal operation. I hope the illustrated tutorial provided in this article can help you better understand and master the use of check valves in China.
