產(chǎn)品介紹 壓力排放吸入閥(GYXB型)、壓力排放閥(GTXC型) GYXB Type Pressure discharge suction valve, GTXC Type A Pressu relief valve 產(chǎn)品慨述 Product outlined the GYXB型壓力排放吸入閥、GYXC型壓力排放閥分別安裝在石油、化工等物料儲罐頂上的安全應急通風裝置。通常與呼吸閥配套使用,是為了避免因意外原因造成罐內(nèi)急劇超壓或真空時,起到壓力泄放或氣體吸入的作用?!? GYXB type suction valve,pressure emissions GYXC type pressure discharge valve installed in respectively oil and chemical material material storage tanks at the top of the safety emergency ventilation device.Usually the respiration valve and supporting the use of in order to avoid accident reason is caused by a sharp overpressure or tank vacuum,a pressure bleeder or gas in haled role. The product is the all-weather sealing structure,to adjust the counterweight to in haled disc and discharge gland open/close,with the constant pressure emissions the constant pressure inhaled,open and flexible,safety and reliability. ◎技術性能 technical characteristic 1、操作壓力:正壓:+1961Pa(+200mmH2O),負壓:-392Pa(-40 mmH2O) 或正、負壓都可由客戶指定。 產(chǎn)品屬性工作原理:在阻火呼吸閥正常工作情況下,緊急泄壓人孔基本保持密封狀態(tài),儲罐處于正常壓力。當呼吸閥正常工作滿足不了因意外原因造成儲罐急劇超壓時,泄壓人孔的泄壓蓋自動頂開,進行緊急泄壓,使罐內(nèi)壓力保持正常;當罐內(nèi)壓力急劇減壓或超真空時,吸入閥便開啟急劇吸入大氣,維護罐內(nèi)正常壓力 .訂貨參數(shù)及范圍:其他說明 防爆級別:BS5501:IIA、IIB、IIC?! ≈圃?、檢測標準:按GB5908-86標準執(zhí)行。 法蘭標準:HG20592~97PN1.0如客戶需用GB、SH、HGJ、JB、ANSI、JIS等標準或改變壓力等級時,請在訂貨合同中注明。交易說明當呼吸閥正常工作滿足不了因意外原因造成儲罐急劇超壓時,泄壓人孔的泄壓蓋自動頂開,進行緊急泄壓,使罐內(nèi)壓力保持正常;當罐內(nèi)壓力急劇減壓或超真空時,吸入閥便開啟急劇吸入大氣,維護罐內(nèi)正常壓力 .
