Analysis of common problems in the selection and use of fire valves

Fire valves are a common type of fire-fighting equipment used to prevent the spread of fires and control their spread. The selection and use of fire valves are crucial, involving the safety and effectiveness of firefighting work. This article will analyze common problems in the selection, installation, maintenance, and inspection of fire valves.

一、 Precautions when selecting fire valves

1. Select suitable fire valves based on the type and purpose of the pipeline. There are many types of fire valves, such as cast iron fire valves, ball valves, diaphragm valves, and so on. When selecting a fire valve, it is necessary to choose a suitable fire valve based on the type and purpose of the pipeline. For example, for high-pressure water pipelines, fire valves that can withstand high pressure should be selected.

2. Choose fire valves with brand protection. The quality and performance of brand fire valves are guaranteed, and after-sales service is also more reliable.

3. Choose fire valves that meet national standards. Fire valves are special safety valves that must comply with national standards when used. If you choose a fire valve that does not meet the standards, there may be safety hazards.

二、 Installation precautions for fire valves

1. Fire valves must be installed in a safe location where flammable and explosive materials are not affected.

2. The installation height of fire valves should comply with regulations. For example, Fire hydrant must be installed on the ground and not more than 1.2 meters above the ground.

3. When installing fire valves, technical acceptance should be passed to ensure that the installation quality meets the regulations.

三、 Maintenance and upkeep of fire valves

1. Regularly check the working status of the fire valve, and replace it in a timely manner if there is any damage or aging.

2. Fire valves should be cleaned regularly and kept clean externally to prevent external debris from entering.

3. The pipeline for installing fire valves should be kept clean to avoid water accumulation or debris blocking the pipeline.

四、 Inspection of fire valves

When checking the fire valve, it is necessary to check whether the fire valve is in a closed state.

2. Check whether the fire valve can be opened and closed normally, and whether the valve is leaking.

3. Check the exterior of the fire valve for damage and replace it promptly if there is any damage.

In summary, the selection and use of fire valves must comply with national standards and regulations to ensure the safety and effectiveness of firefighting work. At the same time, fire valves also require regular maintenance and inspection to ensure their normal operation.
