彈性座封閘閥The elastic valve seat seal
Resilient seated gate valve is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Dark bar elastic valve seat seal with the valve plastic deformation the overall compensation package to achieve a good seal, valve seal to overcome the generally poor, Water Leakage and rusty phenomenon, saving installation space more effectively. Elastic seat sealing soft sealing gate valve can be widely used for fluid pipelines of tap water, sewage, construction, petroleum, chemical industry, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy system as a regulator and the closure device.
應(yīng)用范圍：彈性座封閘閥特別適用于生活飲用水系統(tǒng)、食品醫(yī)藥行業(yè)、工業(yè)給排水及污水處理、天燃?xì)馀c煤氣等，軟密封閘閥也可廣泛用于自來水、污水、建筑、石油、化工、食品、醫(yī)藥、輕紡、電力、船舶、治金、能源系統(tǒng)等流體管線上。
Scope of application: flexible seat seal gate valve is especially suitable for drinking water system, food and pharmaceutical industry, industrial water supply and sewage treatment, natural gas and coal gas, soft sealing gate valve can be widely used for fluid pipelines of tap water, sewage, construction, petroleum, chemical industry, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy system and so on.
結(jié)構(gòu)特點(diǎn)：平底式閥座永嘉閥門供應(yīng)網(wǎng)公司軟密封閘閥底部采用全流域直通式流道設(shè)計(jì)，等同于直管道，無滯流凹腔結(jié)構(gòu)，流阻小，確保流體暢通，不易沉積雜物，也不會(huì)對介質(zhì)造成二次污染。
Structure features: flat style seat Yongjia valve supply network company soft sealing gate valve at the bottom of the use of the whole basin straight channel design, equivalent to the straight pipe, no stagnant cavity structure, small flow resistance, to ensure that the fluid flow is not easy to deposit, debris, will not cause secondary pollution to the media two.
全包覆閘板閘板采用球鐵QT500-7骨架整體包覆高性能橡膠，成熟的硫化技術(shù)和先進(jìn)的硫化工藝，徹底將閘板鐵芯與流體隔離。包覆緊密可靠，其結(jié)合強(qiáng)度符合DVGW要求，即使受到頻繁的擠壓應(yīng)力橡膠也不會(huì)脫落。閥桿螺母與閘板兩體式結(jié)構(gòu)，保證足夠自由度，啟閉靈活并無卡阻現(xiàn)象。
Fully coated gate gate made of ductile iron QT500-7 framework covering high performance rubber, vulcanized mature technology and advanced vulcanization process, complete the gate core and fluid isolation. Coating is compact and reliable, its combination of strength meet the requirements of DVGW, even by the frequent extrusion stress rubber does not drop. The valve stem nut and the two type structure, ensure sufficient freedom, flexible opening and closing no jamming.
在線更換密封圈特殊軸封結(jié)構(gòu)，全開時(shí)可在線不停水更換密封圈；
Online replace sealing ring special seal structure, the fully open to online is not supplied replace sealing ring;
可靠的上密封閥桿與頂蓋間的上密封，采用“內(nèi)3外2”共五道“O”型密封圈結(jié)構(gòu)，與傳統(tǒng)閘閥的填料密封結(jié)構(gòu)相比，密封緊密可靠，磨擦阻力大幅減小。
Reliable seal between the stem and cap seal, the "3 and 2" Five "O" type sealing ring structure, compared with the traditional gate valve packing seal structure, seal tightly and reliably, the friction resistance is greatly reduced.
防腐性能殼體（球鐵QT500-7）內(nèi)外表面靜電噴涂環(huán)氧樹脂粉末，涂層均勻牢固，絕不露鐵； 中腔連接螺栓頂部封膠，隔絕螺栓與環(huán)境的接觸，以防腐蝕。
Anticorrosion performance of shell (ductile iron QT500-7) epoxy resin powder electrostatic spray coating surface, uniform and firm, not dew iron; cavity connecting bolt top sealing glue, isolate the bolt contact with the environment, in order to prevent corrosion.
