How to choose self-pressure valve

Self-pressure valve design and selection based on the following points: 1, calculate the flow of water through the valve. According to the data provided by the sample, and with reference to the size of the interface device, check whether the flow of the valve meets the requirements. 2, choose the appropriate pressure range. Calculate the water system resistance, draw the valve needs to absorb the pressure difference, to determine the pressure range of the valve. 3, According to the calculated flow, pressure range and technical requirements to determine the appropriate valve series, model. The pressure drop of the self-operated pressure differential valve is equal to the minimum pressure drop value of the working pressure difference range. Note: Pump head = pressure drop of self-operated pressure drop + other pressure drop of the system.

Steel Structure Building

The price of steel structure building is favorable, and the safety is guaranteed!
In recent years, steel structure buildings are still very popular, and can be divided into Industrial Steel Buildings and Agricultural Steel Buildings. Industry is mostly used for Steel Structure Workshop Warehouse, and agriculture is mostly used for cowsheds and stables.

Moreover, the construction efficiency of this type of building is high, and different designs can also be carried out, so as long as it can cooperate with regular manufacturers, customized processing buildings are also guaranteed. And from the price point of view, its cost performance is high, and the safety is also guaranteed.

sturdiness
Many people may worry that steel structure buildings are not as strong as traditional buildings, but this is not the case. Because it is made of heavy-duty steel, it has a strong load-bearing capacity and its stability is also guaranteed. It can withstand typhoons, earthquakes, etc., and its steel properties are unique, so it is also guaranteed to be used in harsh environments.

fire effect
Because steel itself is a non-combustible material, and the outer layer has fire-resistant coating and anti-rust coating, and many buildings directly use sandwich panels, so its fire-proof, moisture-proof, and sound-proof effects are also good. of.

waterproof and insect-proof
Steel structure buildings can be effectively waterproof, and the surface of the steel is also galvanized, so the corrosion resistance is also guaranteed. And it also has a good insect-proof effect, so you don't have to worry about being eaten by insects later.

long-term use
Such buildings can be used for a long time, but it is also important to choose light decoration for the interior as much as possible to reduce the overall load bearing of the building. Moreover, the hardness of steel is strong, and it is not easy to deform. It has a long service life and is also good in terms of cost performance.

Environmental performance
In fact, all materials of the steel structure can be recycled and reused, which can reduce the waste of energy and also avoid the generation of construction waste. Therefore, relatively speaking, this kind of building has strong environmental protection performance, and this kind of building will be chosen on many construction sites.

And now many manufacturers can also provide customized processing services, so that it is convenient to customize steel structure buildings, and fast construction can be completed in a short period of time, so that construction costs can also be saved a lot. Therefore, from the perspective of long-term use and cost performance, such buildings are indeed worth choosing.
