Fire gate valve

Fire gate valves are used for shut-off and control of shut-off status on the main pipeline of automatic sprinkler fire extinguishing systems. In addition, it can also be used for interception and interception state control of fixed fire extinguishing systems

The characteristic of the elastic seat seal gate valve is a flat bottomed valve seat, which does not accumulate dirt and ensures excellent sealing; The ductile iron skeleton is coated with stable rubber and vulcanization technology both inside and outside, ensuring a tight and secure fit with excellent geometric dimensions and sealing elasticity

Fire safety is something that should be taken seriously in every situation, and when installing fire pipes, we need to ensure safety. So, when installing fire protection pipelines, should we choose gate valves or butterfly valves

1. Different choices of fire pipes

If the medium in the fire pipeline is steam, then there are more options for gate valves. If it is a fire vertical pipe, then there are more options for butterfly valves

2. The size of the fire pipe diameter

If located in densely populated areas, large-diameter fire pipes are generally chosen when setting up fire pipes. In this case, due to the convenient opening and simple structure of the butterfly valve

If it is located in a less crowded area and there are no flammable or explosive dangerous goods around, a well sealed gate valve can be selected for control

1. Function of Gate Valve

Gate valve is a commonly used pipeline valve, mainly used to control and isolate the flow of media, widely used in various industries, buildings, and public facilities.

. On the inlet pipe of the fire water tank (based on actual reports), gate valves are mainly used to control the flow of water and stop the flow of water, in order to confirm the normal operation and safety of the fire water tank (based on actual reports)

2. How to choose a gate valve

1. Choose the appropriate type of gate valve based on the characteristics of the pool and pipeline

Fire water (based on actual reports) (based on actual reports) (based on actual reports) (based on actual reports) The gate valve used for the pool inlet pipe is generally a manual on-off valve.

. According to the characteristics of the pool and pipeline, it is necessary to choose the appropriate type of gate valve. If it is a large-diameter pipeline, flat gate valves or knife gate valves are generally selected. If it is a small-diameter pipeline, you can choose globe valves or ball valves, etc

2. Choose appropriate materials based on the characteristics of the medium

The selection of gate valve materials is very important for the inlet pipes of the fire water tank (mainly based on actual reports) (mainly based on actual reports) (mainly based on actual reports).

. Due to the fact that fire water (mainly based on actual reports) (mainly based on actual reports) (mainly based on actual reports) pools are generally located outdoors and are easily affected by atmospheric, moisture, and other chemical substances, gate valves should have corrosion resistance (mainly based on actual reports) (mainly based on actual reports) (mainly based on actual reports), good compressive strength, and good sealing performance. Common gate valve materials include cast iron, carbon steel, stainless steel, and copper alloys

3. Proper installation and use of gate valves

Proper installation and use of gate valves are also very important.

. When installing gate valves, it is necessary to pay attention to the installation direction of the gate and the opening and closing direction of the valve. When using gate valves, attention should be paid to the opening and closing force and frequency of the valves to prevent damage caused by excessive use or improper operation

III. Maintenance and upkeep of gate valves

After installing and using gate valves, regular inspections and maintenance are also necessary.

. Especially during the rainy season or when the water tank is out of service, it is necessary to inspect and maintain the gate valve to confirm its normal operation and service life
