Should the tunnel fire pipeline valve be a butterfly valve or a gate valve, and why?

The butterfly valve is small in size, simple in structure, convenient and fast in opening and closing, labor-saving, reliable sealing, and it is not easy to repair the sealing surface of the gate valve after wearing

Dispute Tianjin valve factory for you to answer:

Butterfly valve has low cost, simple structure, easy maintenance, relatively low reliability due to structural characteristics (comparatively speaking), gate valve high cost, high pressure, relatively high reliability, selection is generally based on drawing requirements and procurement costs.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Theoretically, it is completely replaceable. However, if the drawing design is a gate valve, then you need to replace it with a butterfly valve, which needs to be changed by the design institute.

First of all, the pressure and installation location are clear, and butterfly valves can be used if conditions permit, after all, butterfly valves are much cheaper than gate valves. After the completion of the project, there will be a special management of the acceptance of the fire protection unit.

For example: 1. The butterfly valve installed in the riser is generally installed in these places (the outlet of the pump is equipped with butterfly valve, drainage system, upper and lower floors) The riser is basically installed with butterfly valve, first of all, it is not the butterfly valve that is cheap, but the butterfly valve is fast to close and open.

2. The gate valve installed in the water supply pipeline (basically a gate valve with all horizontal pipes) is because under the comparison of quality and stability, the gate valve will be better, and those parts do not need to be quickly switched, so the gate valve with good stability will be selected.

3. Fire water pipeline DN400, when emergency is required to open quickly: it is more appropriate to choose electric butterfly valve, one is the opening time is short, the second is that the large-diameter butterfly valve should be cheaper, and the third is that the butterfly valve is smaller in size and the site space is limited.

It mainly depends on the pressure and the use of working conditions. Generally, the butterfly valve is suitable for large diameter, while the diameter of the gate valve is not too large.

Outdoor trunk pipes generally use gate valves, and butterfly valves can be used instead of butterfly valves in other places. In all respects, butterfly valves are superior to gate valves.
