在污水處理中，以下幾種閥門相對比較容易堵塞:

　　In sewage treatment, the following valves are relatively easy to clog:

　　截止閥

　　globe valve

　　截止閥是依靠閥桿壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質流通。它的結構特點導致其流道曲折，介質在閥內的流動方向改變較大。在污水處理中，污水里含有的各種雜質，如泥沙、纖維、固體顆粒等，流經截止閥時，很容易在閥腔和閥座附近堆積。而且截止閥的閥座通徑通常相對較小，雜質更容易在此處形成堵塞，影響閥門的正常開啟和關

　　Globe valves rely on valve stem pressure to tightly fit the sealing surface of the valve disc with the sealing surface of the valve seat, preventing the flow of the medium. Its structural characteristics result in tortuous flow channels and significant changes in the flow direction of the medium inside the valve. In sewage treatment, various impurities contained in sewage, such as sediment, fibers, solid particles, etc., can easily accumulate near the valve chamber and valve seat when passing through the shut-off valve. Moreover, the valve seat diameter of globe valves is usually relatively small, and impurities are more likely to form blockages here, affecting the normal opening and closing of the valve

　　閉，降低污水的流通效率。

　　Close and reduce the efficiency of sewage circulation.

　　節流閥

　　throttle valve

　　節流閥主要用于調節介質的流量和壓力。它通過改變節流截面或節流長度來控制流體。在污水處理系統中，節流閥通常需要頻繁地調節開度以適應不同的處理工況。當污水中的雜質隨著水流通過節流閥時，由于節流閥的節流口較小，雜質容易在此處聚集。特別是一些纖維狀雜質，可能會纏繞在節流口處，導致節流口堵塞，進而影響閥門對流量和壓力的調節功能，甚至可能造成閥門損壞。

　　Throttle valves are mainly used to regulate the flow rate and pressure of media. It controls the fluid by changing the throttling section or throttling length. In sewage treatment systems, throttle valves usually need to be frequently adjusted to adapt to different treatment conditions. When impurities in sewage flow through the throttle valve, they tend to accumulate here due to the small throttle opening of the throttle valve. Especially some fibrous impurities may wrap around the throttle port, causing blockage and affecting the valve's ability to regulate flow and pressure, and even causing valve damage.

　　隔膜閥隔膜閥是用隔膜作啟閉件，隔斷閥體內腔與閥蓋內腔和驅動部件的閥門。隔膜閥的隔膜下方空間容易積聚污水中的雜質，尤其是一些較重的固體顆粒。當這些雜質積累到一定程度時，會影響隔膜的正常運動，導致閥門無法完全開啟或關閉。此外，如果污水中的粘性物質較多，還可能會附著在隔膜表面，進一步影響閥門的性能，甚至造成堵塞。在實際的污水處理工程中，為了減少閥門堵塞的情況，通常會在閥門前設置過濾裝置，定期對閥門進行維護和清理并且根據污水的特性和處理工藝，合理選擇閥門的類型和規格。

　　Diaphragm valve is a valve that uses a diaphragm as an opening and closing component to isolate the valve body cavity, valve cover cavity, and driving components. The space below the diaphragm of the diaphragm valve is prone to the accumulation of impurities in sewage, especially heavy solid particles. When these impurities accumulate to a certain extent, they will affect the normal movement of the diaphragm, causing the valve to be unable to fully open or close. In addition, if there are many viscous substances in the sewage, they may also adhere to the surface of the diaphragm, further affecting the performance of the valve and even causing blockage. In actual sewage treatment projects, in order to reduce valve blockage, a filtering device is usually installed in front of the valve, and the valve is regularly maintained and cleaned. Based on the characteristics of the sewage and the treatment process, the type and specifications of the valve are reasonably selected.
