                  性能特點:

                  管線球閥使用聚合材料作為閥座密封,密封座用彈簧加載, 在較廣的溫度變化和壓力變化范圍內具有優良的密封性能, 確保在關閉壓差作用下達到無氣泡泄漏的密封,且在最大 壓差下仍可保持最小操作扭矩。

                  The pipeline ball valves have excellent seal function under wide temperature variety and pressure variety because pipe ball valves use polymers compounding as seat seal which uses spring loaded, therefore no air bulb leakage will be retained under closing differential pressure and Min. operation torque will be attained under Max. differential pressure.


                  鍛鋼結構

                  球閥的閥體和連接體采用鍛鋼材料,阓門內件經過精心選擇,確保在各種工況下能可靠地工作。體的壁厚和閥體螺栓的連接強度按美國標準ASME B16.34的要求,經過嚴密計算,確保相應的閥體壓力等級和結合部的可靠強度。

                   

                  操作扭矩低

                  球閥采用固定球結構,浮動餒座,在操作壓力下達到較小的扭矩。采用了具有自潤PTFE的金屬軸套,與高強度、高光潔度的閥桿配合,使摩擦系數降到最低。

                   

                  Forged steel structure

                  The valve body and connector of ball valve are made of forged steel while its inner parts are exquisitely selected, so as to ensure the product to operate reliably under various work conditions, The wall thickness of the body and the connection strength of valve bolts is performed as per ASME B15.34. the relating pressure class and reliable strength of joint is insured through strict calculation.

                   

                  Low operating torque

                  Fixed ball and floating seat is applied in ball valve, by which ow torque can be attained under operating pressure. Self-lubricating PTFE metal axle sleeve is used with high-strength and high-polished stem to enable friction coefficient smallest.


                   

                  密封可靠

                  鑲嵌有適合不同壓力級的聚合材料密封座是浮動的,并由彈簧加載,在關閉位置時,始終與球體保持緊密接觸,達到可靠的密封。每臺閥門在出廠前均按AP6D進行全面驗收,也可按API598或GB/T13927進行驗收,在確保其結果完全符合要求并出具試驗報告后才可出廠。

                   

                  Reliable sealing

                  The polymeric sealing seat suitable for various pressure classes is floating and loaded by spring, keep close contact with the body at Off position, thus reliable sealing is reached Before delivery, each valve is wholly examined as per API 6D, API598 or GB/T 13927 and test qualified in the written test report.


                   

                  輔助閥座密封

                  通經大于等于6英寸(DN150)的球閥設計有輔助閥座密封系統。當軟閥座密封受到一定的損傷,出現微量泄露時,通過向輔助密封系統注射的密封劑可輔助密封。輔助密封系統在必要時也可用來對閿座區域進行沖洗潤滑,以保持其清潔。

                  注:小于等于4英寸(DN100)的球閥閥體上沒有一個清洗閥,該清洗閥為注射清潔劑而用,無輔助密封功能。

                   

                  Auxiliary valve seat sealing

                  Shown in the following diagram, the ball valve its diameter is greater than and equal to 6 inches (DN150)is provided with auxiliary valve seat sealing system. When soft sealing is damaged for a certain degree and minor leakage is occurred, the auxiliary is obtained by the sealant injected by auxiliary sealing system. The system also can wash and lubricate the seat as necessary in order to retain the Cleanness.

                  Note: (As shown in Diagram 1)a cleaning valve is set at ball valve body its diameter is less than and equal to 4 inches(DN 100), this cleaning valve is available for injecting cleaner and has no sealing function.


                   


                  可靠的閥桿和閥體密封

                  球閥使用符合國際先進標準的氟橡膠O形圈和石墨墊片作為閥桿密封和閥體密封材料,確保了閥門在各種工況下均有可靠的密封。根據工況或用戶的要求,還可提供防止減壓爆裂的氟橡膠O形圈作為密封材料,以保證在壓力劇烈波動的情況下達到更為可靠的閿桿和閥體密封。此外,大部分閥門的閥桿安裝有輔助密封裝置。

                   

                   

                   

                  Reliable sealing to stem and body

                  The stem and body sealing materials respectively employ fluorubber O-ring and graphite gasket meeting the requirements of international advanced standards to ensure reliable sealing under various work conditions.Fluorubber O-ring preventing from pressure reduction explosion can also be applied for sealing materials in order to ensure the sealing of stem and body under

                  severe fluctuation. Besides, mos: of stems are installed with auxiliary sealing device.
