在高層建筑給水、消防管道及大型水泵出口處，停泵瞬間產(chǎn)生的水錘效應(yīng)是破壞管道系統(tǒng)的“隱形殺手”。300X-100-16緩閉式止回閥正是為破解這一難題而生的智能型閥門(mén)，它集電動(dòng)閥、逆止閥和水錘消除器三種功能于一體，是供水系統(tǒng)的安全管家。

The water hammer effect generated when the pump stops at the outlet of the water supply, fire protection pipelines, and large water pumps in high-rise buildings is a "hidden killer" that damages the pipeline system. The 300X-100-16 slow closing check valve is an intelligent valve designed to solve this problem. It integrates three functions: electric valve, check valve, and water hammer eliminator, and is the safety manager of the water supply system.

該閥門(mén)通過(guò)精密的水力控制系統(tǒng)實(shí)現(xiàn)“緩開(kāi)、速閉、緩閉”的三階段動(dòng)作。當(dāng)水泵啟動(dòng)時(shí)，控制室排水速度大于進(jìn)水速度，主閥盤(pán)在進(jìn)口壓力推動(dòng)下緩慢開(kāi)啟；當(dāng)停泵水流開(kāi)始回流時(shí)，回流水進(jìn)入控制室，推動(dòng)閥盤(pán)先快速關(guān)閉大部分行程（速閉），隨后在控制室壓力的作用下出彩緩慢地關(guān)閉剩余間隙（緩閉）。通過(guò)調(diào)節(jié)針閥和球閥的開(kāi)度，可以合理控制緩閉的時(shí)間，從而巧妙吸收并消除停泵水錘。

The valve achieves a three-stage action of "slow opening, quick closing, and slow closing" through a precise hydraulic control system. When the water pump is started, the drainage speed in the control room is greater than the inlet speed, and the main valve disc slowly opens under the push of inlet pressure; When the water flow starts to flow back after stopping the pump, the return water enters the control room and pushes the valve disc to quickly close most of the stroke (quick closing), and then slowly close the remaining gap (slow closing) under the pressure of the control room. By adjusting the opening of the needle valve and ball valve, the slow closing time can be precisely controlled, thereby perfectly absorbing and eliminating pump water hammer.

300X-100-16型號(hào)代表其公稱(chēng)通徑為100mm，公稱(chēng)壓力為1.6MPa。閥體通常采用QT450球墨鑄鐵，耐腐蝕且強(qiáng)度高。它不僅有效防止了介質(zhì)倒流和水泵反轉(zhuǎn)，更出彩大地提高了管網(wǎng)的安全可靠性。正確的安裝、定期的控制管路清理以及密封件檢查，是確保這款智能閥門(mén)長(zhǎng)期穩(wěn)定發(fā)揮“水錘消除”功能的關(guān)鍵。

The 300X-100-16 model represents a nominal diameter of 100mm and a nominal pressure of 1.6MPa. The valve body is usually made of QT450 ductile iron, which is corrosion-resistant and has high strength. It not only effectively prevents medium backflow and pump reversal, but also greatly improves the safety and reliability of the pipeline network. Proper installation, regular cleaning of control pipelines, and inspection of seals are key to ensuring the long-term stable performance of this intelligent valve's "water hammer elimination" function.
