◎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、化工等物料罐頂上的安全應(yīng)急通風(fēng)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(shí)，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.

◎工作原理 Working Principle

在呼吸閥正常工作的情況下，GYXB型壓力排放吸入閥、GYXC型壓力排放閥基本保持密封狀態(tài)，儲(chǔ)罐處于正常壓力。當(dāng)呼吸閥正常工作滿足不了因意外原因造成儲(chǔ)罐壓力急劇超壓時(shí)，GYXB型壓力排放吸入閥或GYXC型壓力排放閥的泄壓蓋自動(dòng)頂開，進(jìn)行緊急泄壓，使罐內(nèi)壓力保持正常；當(dāng)罐內(nèi)壓力急劇減壓或超真空時(shí)，吸入閥便開啟急劇吸入大氣、維護(hù)罐內(nèi)正常壓力，以保護(hù)儲(chǔ)罐安全。所不同的是GYXB型即可吸入、又可排放；而GYXC型只能排放，不能吸入，請(qǐng)用戶在選型時(shí)予以區(qū)別。

In the respiration valve normal wock,situation,GYXB type suction valve,pressure emissions GYXC type pressure discharge valve seal basic keep state,a tank under normal pressure.When the breathing valve normal work can't satisfy the because accident caused a sharp pressure tank pressure,GYXB type pressure emissions suction valve or GYXC type pressure pressure relief valve discharge cover to be automatic top open,make emergency relief pressure,make container maintain normal pressure;when pressure tank or the vacuum pressure sharply,the suction valve and opened sharply inhaled air,maintain normal pressure tank,in order to protect the safety storage tanks,what is different GYXB As can be inhaled,type and discharge;And GYXC type can only emissions,can't breathe,please users in the model selection to be different.
