As follows:

1. When the water supply pipeline is introduced from the entrance, it should be set on the inside of the protective airtight door; When introduced from the civil air defense enclosure structure, it should be set on the inner side of the civil air defense enclosure structure; When passing through the protective airtight partition wall between the protective units, it should be set on the pipes on both sides of the protective airtight partition wall.

2. The nominal pressure of the protective valve should not be less than.

3. The protective valve should be a gate valve or globe valve with a stainless steel or copper core.

Valve is a mechanical device that controls the flow, direction, pressure, temperature, etc. of the flowing fluid medium, and the valve is the basic component of the pipeline system. Valve fittings are technically the same as pumps and are often discussed as a separate category. The valve can be operated manually or with a handwheel, handle or pedal, and can also be controlled to change the pressure, temperature and flow rate of the fluid medium.

These changes can be operated continuously or repeatedly, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used as needed to regulate the changing set points of flow through the pipes based on external inputs. The automatic control valve does not need to be operated manually, according to its input and settings, so that the valve can accurately control the requirements of the fluid medium.

According to the material, the valve is also divided into cast iron valve, cast steel valve, stainless steel valve, chromium-molybdenum steel valve, chromium-molybdenum vanadium steel valve, duplex steel valve, plastic valve, non-standard customized and other valve materials.

Explosion-proof valves are generally used in civil air defense projects, and the main purpose is to prevent external risk factors from invading the inside of the shelter or leaking out of the safety problems caused by the shelter. The following are the requirements for civil anti-explosion valves::

2.Sealing performance requirements: The sealing performance of the explosion-proof valve should meet the relevant national standards to ensure that the air will not leak out in the shelter and can effectively prevent external harmful substances from entering the shelter.

3.Anti-corrosion performance requirements: The material of the explosion-proof sock wide valve should have excellent corrosion resistance, because the refuge is used in a closed period of long branches, if the material is not corrosion-resistant, it will affect the service life of the explosion-proof valve.

4.Emission performance requirements: The civil air defense explosion-proof valve should have the ability to evacuate pollutants in the shelter to ensure that the exhaust gas and harmful substances in the shelter can be discharged in time in the event of a dangerous accident to protect the life safety of personnel.

5.Reliable performance requirements: The civil air defense explosion-proof valve should have stable and reliable performance in the usual use process, and will not lose its function due to problems such as material aging and parts damage.

The above are some requirements for civil anti-explosion valves, and the specific requirements can be adjusted according to the actual situation.

Summary. The installation of the explosion-proof valve is directional, and the positive direction of the shock wave is the direction of movement of the main valve plate towards the spring compression, that is, the direction of closing the valve. In the opposite direction, only a small amount of traffic can be passed.

The explosion-proof wave valve is a special protective equipment for basement protection, and it is an important facility for shock wave protection, with voltage stabilization and dissipation. Under normal circumstances, the circumferential door is in the normally open state, and the system medium is normal and unimpeded, and when the impact crosses the valve, the main valve valve plate is quickly closed under the shock wave pressure, and the shock wave is blocked at the outer end; Part of the impact in the valve has been under the action of the wave elimination valve, the guide wave chamber, due to the diffusion action, the shock wave pressure is rapidly reduced, the damage of the shock wave is eliminated, and the protection and protection are played

3.Anti-corrosion performance requirements: the material of the anti-explosion valve should be matched with excellent corrosion resistance, because the refuge is closed for a long time, if the material is not corrosion-resistant, it will affect the service life of the explosion-proof valve.

Dear, the explosion-proof valve can be installed vertically.

I just wanted to ask if the explosion-proof valve can be installed upright.

Explosion-proof valves can be installed in a standing position.

Hello, in the civil air defense system, if there is a need to isolate between the two water pipes or to control the water flow, you can consider installing valves on both sides. This makes it easy to control, regulate and maintain the water flow. The benefits of retrofitting valves include:

1.Isolation function: The valve can isolate the water flow between the two water pipes, and when the water flow needs to be closed or cut off, it can be achieved by closing the valve.

2.Flow control: Valves can be used to adjust the size of the water flow, increasing or decreasing the amount of water as needed.

3.Repair and maintenance: If a water pipe on one side needs to be repaired or replaced, by closing the corresponding valve, the whole system can be avoided from stopping the water or affecting the normal operation of other parts.

However, whether a valve needs to be installed in a specific situation is determined according to the actual needs and design requirements. Therefore, it is recommended to consult a professional engineer or relevant technician to evaluate and make decisions according to the specific situation. They will take into account the characteristics of the system, safety, ease of operation, and other factors to make the most appropriate decision.

Summary. Hello, the fire water supply pipeline is a fire hydrant or sprinkler pipe in the fire pipeline, but the fire pipe also includes the fire drainage pipe.

Hello, the fire water supply pipeline is a fire hydrant or sprinkler pipe in the fire pipeline, but the fire pipe also includes the fire drainage pipe.

Literally, there is nothing to say, and the fire rental pipeline refers to the pipeline materials used for fire fighting, connecting fire fighting equipment and equipment, and transporting fire fighting water, gas or other media. Due to special needs, there are special requirements for the thickness and material of the fire pipe, and the red paint is sprayed to transport the fire water. Fire pipes are divided into ductile iron pipes, copper pipes, stainless steel pipes, alloy pipes, composite pipes, and plastic pipes.
