Fire Fighting & Safety Equipment Supplier - Butterfly Valves and its characters

 

Fire Fighting Safety Equipment Supplier

There are many types of butterfly valves, including quick cut-off and continuous adjustment, Pneumatic butterfly valves , electric butterfly valves are mainly used for liquid and gas low pressure large diameter pipelines. It is suitable for occasions where the pressure loss is not high, flow adjustment is required, and the opening and closing requirements are fast; usually the temperature is below 300 ℃ and the pressure is below 40 kg (butterfly valves generally use low pressure, like domestic ones. It is rare to achieve CL600). The medium is generally used for water and gas, and the medium is not demanding. Granular medium can also be used.

As a sealed butterfly valve, it brought rapid development after the emergence of synthetic rubber, so it is a new type of shut-off valve. Butterfly valves were mainly used for low-pressure valves, and the valve seat was made of synthetic rubber. By the 1990s, due to increased exchanges with foreign countries, hard seal  but, hard seal butterfly valves  developed rapidly. At present, there are many valve factories that can produce medium-pressure metal-sealed butterfly valves stably, which makes the application field of butterfly valves wider.



The media that the butterfly valve can transport and control are water, condensate, circulating water, sewage, sea water, air, gas, liquid natural gas, dry powder, mud, fruit pulp and mixtures with suspended solids.

Butterfly valves are suitable for flow regulation. 

Since the pressure loss of the butterfly valve in the pipeline is relatively large, about three times that of the gate valve,  when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the strength of the butterfly plate to withstand the pressure of the pipeline medium should also be considered. In addition, it is necessary to consider the limitation of the working temperature of the elastic valve seat material at high temperature. The structural length and overall height of the butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making large-diameter valves. When the butterfly valve is required to control the flow, the most important thing is to correctly select the size and type of the butterfly valve so that it can work properly and effectively.



1. Generally, in throttling, regulating control and mud medium, the structure length is short and the opening and closing speed is fast (1/4 revolution). Low pressure cut-off (small pressure difference), butterfly valve is recommended.

2. The butterfly valve can be used when two-position adjustment, narrow passage, low noise, cavitation and vaporization phenomenon, a small amount of leakage into the atmosphere, and abrasive media.

3. When the butterfly valve is used under special conditions, such as throttling adjustment, or strict sealing requirements, or severe wear, low temperature (cryogenic) and other operating conditions, it is necessary to use a specially designed metal seal with a triple eccentric or double eccentric adjustment device Special butterfly valve for ground.

4. The center line butterfly valve is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, and oil that require complete sealing, zero gas test leakage, high life requirements, and working temperature of -10℃~150℃ And various acid and alkali and other pipelines.

5. The soft-sealed eccentric butterfly valve is suitable for two-way opening and closing and adjustment of ventilation and dust removal pipelines. It is widely used in gas pipelines and waterways in metallurgy, light industry, electric power, and petrochemical systems. Sendhamarai Engineering is the authorised dealer of Lehry Valves

Why Fire sprinkler system commonly used in all commercial sector?

 

 

What is a Fire sprinkler system?

Water Sprinkler System For Fire Suppression:

It is water-based automatic fire detection and suppression system consist of a piping network, sprinklers nozzle heads, quartz bulb (Different temperature rating) for fire detection, deluge valve and fire water pumps with water storage.





Benefits of Firewater sprinkler systems:

1.) Early Detection and suppression of Fire

2) Save Life and property

3) Restrict Spread of fire to other Areas

4) Reduce manpower for fire fighting

Drawbacks :

1.) Accidental actuation of the system can damage valuables

2.) May damage electronic and electrical equipment.

3.) Water is an electrical conductor


Why Fire sprinkler system commonly used in all fire and safety sector?

Advantages are:

Fire Sprinkler System can be almost any size - from your yard to a large center pivot system covering many acres.

Fire sprinkler system have the potential to apply the water when needed.

Fire sprinkler system allow you to keep your yard looking good with almost not worry as you can have them set on timers.

You can easily check to see if they are working.



What's the best type of sprinkler?

Fire Sprinklers typically fall under three categories: rotary, oscillating, and impact. Let’s look at each type so you can decide which would work best for your lawn.

Oscillating:

When most people see a normal sub urban lawn with a sprinkler, it is a reasonable chance that they are picturing an oscillating sprinkler system. These fire sprinklers have a long tube with several sprinkler holes. When the sprinkler reaches a certain level of pressure, water shoots out of the perforations, and the force of the water causes the tube to wave back and forth. This is one of the finest sprinklers for kids to play in during the summer months since they can leap over it.

Rotary/stationary:

Rotary sprinklers are made up of multiple arms with spray tips linked to a revolving head. When you turn on the water, the head rotates and the sprinkler arms spray water in a round pattern. A fixed sprinkler, which disperses water in a somewhat more squared-off pattern, is also available. Rotary and stationary sprinklers are both helpful, but they only function in the pattern that they are built for or configured to. This works well for smaller lawns.

Impact:

Pressure builds up inside these sprinklers, and works its way towards the spray head, causing the impact hammer to be pushed aside. When the hammer is moved out of the way, spurts of water can shoot across your yard in a jet. They may be programmed to cover a certain region or a whole circle. This type of sprinkler is fairly popular in both permanent and stationary versions, and it is extensively utilised in parks and other big grass settings.
