標準光閥法蘭蝶閥和兩種蝶閥有什么區別？這兩種蝶閥的應用范圍非常廣泛。剛接觸這個行業的朋友可能會有這個問題。讓我們給你一個全面的分析！滬工閥門代理告訴你首先，蝶閥中的法蘭和對夾有兩種連接方式。滬工閥門代理就價格而言，夾式便宜，價格大約是法蘭的三分之二。選擇進口閥門時，盡量使用夾式，價格便宜，重量輕。

What is the difference between standard light valve flange butterfly valve and two types of butterfly valves? These two types of butterfly valves have a very wide range of applications. Friends who are new to this industry may have this problem. Let us provide you with a comprehensive analysis! The Shanghai valve agent will tell you that there are two connection methods for flanges and clamps in butterfly valves. In terms of price, the clamp type valve agent is cheap, with a price about two-thirds that of the flange. When choosing imported valves, try to use clamp type valves, which are inexpensive and lightweight.

夾緊式閥門螺栓長度較長，對施工精度要求較高，若兩側法蘭不對，螺栓剪切力較大，閥門容易泄漏。夾緊式閥門螺栓一般較長。滬工閥門代理告訴你在高溫條件下，螺栓膨脹可能導致泄漏，因此在高溫條件下不適合大直徑管道。此外，夾緊蝶閥不能用于管道末端和下游需要拆卸的場合，因為當下游法蘭被拆卸時，夾緊閥會脫落。在這種情況下，必須在另一個較短的部分進行拆卸。法蘭蝶閥沒有上述問題，但成本相對較高

The bolt length of clamped valves is relatively long and requires high construction accuracy. If the flanges on both sides are not correct, the bolt shear force will be large, and the valve is prone to leakage. Clamping valve bolts are generally longer. The Shanghai valve agent tells you that under high temperature conditions, bolt expansion may cause leakage, so it is not suitable for large-diameter pipelines under high temperature conditions. In addition, clamping butterfly valves cannot be used at the end of pipelines and downstream where disassembly is required, as the clamping valve will come off when the downstream flange is disassembled. In this case, it is necessary to disassemble in another shorter section. The flange butterfly valve does not have the above-mentioned problems, but the cost is relatively high

夾緊蝶閥閥體兩端沒有法蘭，只有幾個導向螺栓孔。閥門通過一組螺栓螺母與端部法蘭連接。滬工閥門代理告訴你相比之下，拆卸更方便，閥門成本更低，但缺點是密封面有問題，必須拆卸兩個密封面。法蘭式蝶閥體兩端有法蘭，與管法蘭相連。密封比較可靠，但是法蘭蝶閥的成本比較高。當法蘭蝶閥處于完全打開位置時，蝶板的厚度是介質通過閥體阻力。因此，通過閥門產生的壓降非常小，因此具有良好的流量控制特性。

There are no flanges at both ends of the clamped butterfly valve body, only a few guide bolt holes. The valve is connected to the end flange through a set of bolts and nuts. The Shanghai valve agent tells you that compared to others, disassembly is more convenient and the cost of the valve is lower. However, the disadvantage is that there is a problem with the sealing surface, and two sealing surfaces must be disassembled. The flange type butterfly valve body has flanges at both ends, which are connected to the pipe flange. The sealing is relatively reliable, but the cost of flange butterfly valves is relatively high. When the flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance of the medium passing through the valve body. Therefore, the pressure drop generated by the valve is very small, thus having good flow control characteristics.
