進口搪瓷，搪玻璃隔膜閥主要性能 Main performance

搪瓷，搪玻璃隔膜閥是將含硅量高的瓷釉涂于金屬表面，通過950℃搪燒，使瓷釉密著于金屬鐵胎表面制成。因此，它具有類似玻璃的化學穩定性和金屬強度的雙重優點，是一種優良的耐腐蝕設備元件。隔膜閥是用閥腔內的膜片作啟閉件封閉流道、截斷流體、并將閥體內腔和閥蓋內腔隔開的截止閥retz品牌  Enamel and glass lined diaphragm valves are made by coating the enamel with high silicon content on the metal surface and firing it at 950 ℃ to make the enamel close to the surface of the metal iron tire. Therefore, it has the double advantages of chemical stability and metal strength similar to glass, and is an excellent corrosion-resistant equipment element. Diaphragm valve is a stop valve that uses the diaphragm in the valve cavity as the opening and closing part to close the flow channel, cut off the fluid, and separate the inner cavity of the valve body from the inner cavity of the bonnet.

搪瓷，搪玻璃隔膜閥的工作介質接觸的僅僅是隔膜和閥體，操縱機構與介質通路隔開，不但保證了工作介質的純凈，同時也防止管路中介質沖擊操縱機構工作部件的可能性；閥桿處不需要采用任何形式的單獨密封。所以該閥能理想地控制多種工作介質，膜片常用橡膠、塑料等彈性、耐腐蝕、非滲透性材料制成，尤其適合帶有化學腐蝕性 The working medium of enamel and glass enameled diaphragm valves only contacts the diaphragm and valve body. The operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium, but also prevents the possibility of the medium in the pipeline impacting the working parts of the operating mechanism; There is no need to use any form of separate seal at the valve stem. Therefore, the valve can ideally control a variety of working media. The diaphragm is usually made of elastic, corrosion-resistant and impermeable materials such as rubber and plastic, especially suitable for chemical corrosion

進口搪瓷，搪玻璃隔膜閥特點∶ Performance characteristics

1、耐酸性：對各種有機酸、無機酸、有機溶劑均有較好的抗蝕性。搪玻璃試樣置于20%HCI溶液中煮沸48h，腐蝕速率為0.9lg/m2.d（優等品指標為1.0g/m2.d）Acid resistance: it has good corrosion resistance to various organic acids, inorganic acids and organic solvents. The glass lined sample is boiled in 20% HCI solution for 48h, and the corrosion rate is 0.9lg/m2. D (the index of superior products is 1.0g/m2. D)

2、耐堿性：搪玻璃對堿性溶液抗蝕性較酸溶液差。搪玻璃試樣置于1N氫氧化鈉溶液腐蝕，試驗溫度80℃時間24h。腐蝕速率為6.76g/m2.d（優等品指標為7.0g/m2.d）The corrosion resistance of glass lining to alkaline solution is worse than that of acid solution. The glass lined sample is corroded in 1n sodium hydroxide solution at 80 ℃ for 24h. Corrosion rate is 6.76g/m2. D (excellent product index is 7.0g/m2. D

3、操作溫度：設備加熱和冷卻時，應緩慢進行。搪玻璃設備使用溫度為0－200℃，耐溫急變性≥200℃ Heating and cooling of glass lined equipment shall be carried out slowly. The service temperature of glass lined equipment is 0-200 ℃, and the temperature resistance is not less than 200 ℃

4、瓷層厚度：瓷層厚度0.8-2.0mm，搪玻璃設備附件的瓷層厚度0.6-1.8mm The thickness of the porcelain layer is 0.8-2.0mm, and the thickness of the porcelain layer of the glass-lined equipment accessories is 0.6-1.8mm

5、耐壓電：具有良好的絕緣性，當搪玻璃在規定厚度內用20KV高頻電火花檢查瓷層時，高頻電火花不能擊穿瓷層 It has good insulation. When the porcelain layer is inspected by 20kV high-frequency electric spark within the specified thickness of the enamel, the high-frequency electric spark cannot break through the porcelain layer

6、耐沖擊性：玻璃層的內應力越小，彈性越好，硬度越大，抗彎抗壓強度越高，則耐沖擊就越好。玻璃層在規定厚度內，用直徑30mm，重量112g鋼球沖擊時，其沖擊功為272×10-3J（優等品指標為260×10-3J）The smaller the internal stress of the glass layer, the better the elasticity, the greater the hardness, and the higher the flexural and compressive strength, the better the impact resistance. When the glass layer is impacted by a steel ball with a diameter of 30mm and a weight of 112G within the specified thickness, its impact energy is 272 × 10-3j (excellent product index is 260 × 10-3J）
