上海申弘閥門有限公司
上海申弘閥門有限公司作為世界的管路系統(tǒng)專家,GF致力于研發(fā)更、更環(huán)保的管路產(chǎn)品,GFH前發(fā)布了一款新型隔膜閥,從原料到成品無不透露出對(duì)綠色變革的追求。隔膜閥的結(jié)構(gòu)形式與一般閥門大不相同,是一種新型的閥門,是一種特殊形式的截?cái)嚅y,它的啟閉件是一塊用軟質(zhì)材料制成的隔膜,把閥體內(nèi)腔與閥蓋內(nèi)腔及驅(qū)動(dòng)部件隔開,現(xiàn)廣泛使用在各個(gè)領(lǐng)域。上海申弘閥門有限公司主營閥門有:減壓閥(氣體減壓閥,可調(diào)式減壓閥,波紋管減壓閥,活塞式減壓閥,蒸汽減壓閥,先導(dǎo)式減壓閥,空氣減壓閥,氮?dú)鉁p壓閥,水用減壓閥,自力式減壓閥,比例減壓閥)、安全閥、保溫閥、低溫閥、球閥、截止閥、閘閥、止回閥、蝶閥、過濾器、放料閥、隔膜閥、旋塞閥、柱塞閥、平衡閥、調(diào)節(jié)閥、疏水閥、管夾閥、排污閥、排氣閥、排泥閥、氣動(dòng)閥門、電動(dòng)閥門、高壓閥門、中壓閥門、低壓閥門、水力控制閥、真空閥門、襯膠閥門、襯氟閥門。常用的隔膜閥有襯膠隔膜閥、襯氟隔膜閥、無襯里隔膜閥、塑料隔膜閥。隔膜閥,隔膜閥是在閥體和閥蓋內(nèi)裝有一撓性隔膜或組合隔膜,其關(guān)閉件是與隔膜相連接的一種壓縮裝置。閥座可以是堰形,也可以是直通流道的管壁。隔膜閥的優(yōu)點(diǎn)是其操縱機(jī)構(gòu)與介質(zhì)通路隔開,不但保證了工作介質(zhì)的純凈,同時(shí)也防止管路中介質(zhì)沖擊操縱機(jī)構(gòu)工作部件的可能性。此外,閥桿處不需要采用任何形式的單獨(dú)密封,除非在控制有害介質(zhì)中作為安全設(shè)施使用。隔膜閥中,由于工作介質(zhì)接觸的僅僅是隔膜和閥體,二者均可以采用多種不同的材料,因此該閥能理想地控制多種工作介質(zhì),尤其適合帶有化學(xué)腐蝕性或懸浮顆粒的介質(zhì)。隔膜閥的工作溫度通常受隔膜和閥體襯里所使用材料的限制,它的工作溫度范圍大約為-50~175℃。隔膜閥結(jié)構(gòu)簡單,只由閥體、膜片和閥頭組合件三個(gè)主要部件構(gòu)成。該閥易于快速拆卸和維修,更換隔膜可以在現(xiàn)場及短時(shí)間內(nèi)完成。
這款新型隔膜閥由設(shè)計(jì),它在材料上具有令新的無金屬螺栓隔膜閥設(shè)計(jì),但是同傳統(tǒng)隔膜閥相比流量卻加倍。經(jīng)過幾十年來在活接的驗(yàn)證,上海申弘閥門有限公司將螺紋應(yīng)用于新隔膜閥:=簡便、壓緊力均勻分布、無需反復(fù)上J緊。新型隔膜閥僅保留了一個(gè)螺帽式的七蓋,舍棄了傳統(tǒng)的四螺栓設(shè)計(jì),實(shí)現(xiàn)了*的無腐蝕連接。非常幣要的是,當(dāng)溫度變化時(shí),這個(gè)塑料塑料連接點(diǎn)由于具有同質(zhì)特性,從避免泄漏的發(fā)。
通過優(yōu)化惻體結(jié)構(gòu),新閥門具有更線性的流量曲線。另外,三通閥門的開口更加接irr管難,死K
得到小化,系統(tǒng)更加衛(wèi)生,其流量和調(diào)節(jié)特性接近隔膜閥。而且,新型隔膜閥具有自排空閥,型腔結(jié)構(gòu)也對(duì)結(jié)晶介質(zhì)不敏感。同時(shí),作為氣動(dòng)隔膜閥膜閥來說,GF新型隔膜閥所有執(zhí)行器進(jìn)氣幾
可以每次90度、多次旋轉(zhuǎn)到需要的位置。作為世界的管路系統(tǒng)專家,GF致力于研發(fā)更、更環(huán)保的管路產(chǎn)品,GF日前發(fā)布了一款新型隔膜閥,從原料到成品無不透露出對(duì)綠色變革的追求。 這款新型隔膜閥由GF的德國設(shè)計(jì)師RainerKech設(shè)計(jì),它在材料上具有全新的無金屬螺栓隔膜閥設(shè)計(jì),但是同傳統(tǒng)隔膜閥相比流量卻加倍。經(jīng)過幾十年來在活接上的驗(yàn)證,GF將螺紋應(yīng)用于新隔膜閥:簡便、壓緊力均勻分布、無需反復(fù)上緊。新型隔膜閥僅保留了一個(gè)螺帽式的上蓋,舍棄了傳統(tǒng)的四螺栓設(shè)計(jì),實(shí)現(xiàn)了*的無腐蝕連接。非常重要的是,當(dāng)溫度變化時(shí),這個(gè)塑料-塑料連接點(diǎn)由于具有同質(zhì)特性,從而避免了泄漏的發(fā)生。 通過優(yōu)化閥體結(jié)構(gòu),新閥門具有更線性的流量曲線。另外,三通閥門的開口更加接近管壁,死區(qū)得到小化,系統(tǒng)更加衛(wèi)生,其流量和調(diào)節(jié)特性接近于角座閥。而且,新型隔膜閥具有自排空設(shè)計(jì),型腔結(jié)構(gòu)也對(duì)結(jié)晶介質(zhì)不敏感。同時(shí),作為氣動(dòng)隔膜閥來說,GF新型隔膜閥所有執(zhí)行器進(jìn)氣口可以每次90度、多次旋轉(zhuǎn)到需要的位置。 新型隔膜閥備件簡單、更換輕松,膜片壓緊力均勻分布而且密封等級(jí)很高。膜片界面的設(shè)計(jì)原則是螺紋連接不會(huì)傳遞任何應(yīng)力到膜片軸上,柔性過渡和徑向截面的流道設(shè)計(jì)使得新隔膜閥同傳統(tǒng)隔膜閥相比流通量加倍。這個(gè)設(shè)計(jì)的實(shí)現(xiàn)有賴于GF*的制造工藝,同時(shí)死區(qū)小化大程度上保證了衛(wèi)生性。由于避免了強(qiáng)制湍流,磨損和噪音也大大減少。在減少壓損之外,增加的流量意味著節(jié)約能源,降低運(yùn)行成本,新型隔膜閥在相同能耗條件下實(shí)現(xiàn)了少99%的流量增長。As the world's leading experts in pipeline systems, GF is committed to developing better, more environmentally friendly product lines, GF has launched a new type of diaphragm valves, from raw materials to finished products are all revealed the pursuit of the green revolution. The new diaphragm design RainerKech by GF German design, which has new material on non-metallic diaphragm bolt design, but compared with the conventional diaphragm flow was doubled. After living for decades in the validation of connected, GF diaphragm will be applied to the new thread: easy clamping force evenly distributed, without repeatedly tightened. New diaphragm retaining only a nut-like cover, abandoning the traditional four-bolt design to achieve a compley corrosion-free connections. It is very important, when the temperature changes, the plastic - plastic connection points as homogeneous characteristics, thus avoiding the occurrence of leakage. By optimizing the body structure, the new valve has a more linear flow curve. In addition, three-valve opening closer to the wall, dead to be minimized, the system is more health, and regulate its flow characteristics close to the angle seat valve. Moreover, the new diaphragm with self-draining design, the cavity structure is not sensitive to the crystallization medium. Meanwhile, as for pneumatic diaphragm valves, GF all the new diaphragm actuator inlet to each 90 degrees rotation to the desired location number. New diaphragm spare parts simple, easy to replace, patch clamping force evenly and seal level is high. Membrane interface design principles are threaded connection does not pass any stress to the diaphragm axis, radial cross section of the flexible transition and flow design makes the new diaphragm with diaphragm compared to traditional circulation doubled. The unique design of the implementation depends on the GF manufacturing process, while minimizing dead zone to ensure the greatest degree of health. In order to avoid a forced turbulence, wear and noise are greatly reduced. In addition to reducing the pressure loss, increased traffic means saving energy and reducing operating costs, energy consumption of the new diaphragm in the same conditions to achieve at least 99% of the traffic growth.
