安全閥系列  Safety Valve

應(yīng)用AQ3系列安全閥是衛(wèi)生級不銹鋼閥門，它的安全設(shè)計使得它能保護(hù)設(shè)備，所以它安裝在

排放壓力的回路，對管路、泵、裝置、儲罐等起安全保護(hù)作用。廣泛應(yīng)用于食品、飲料、乳制

品、制藥、啤酒等行業(yè)。

工作原理

AQ3系列安全閥是通過調(diào)整彈簧的壓緊螺母來校準(zhǔn)一個特定壓力。校準(zhǔn)壓力是為了避免設(shè)備損

壞而定的安全壓力值。在正常的的工作壓力下，閥門是關(guān)閉的;當(dāng)系統(tǒng)壓力超過校準(zhǔn)壓力

時，閥門打開。管道系統(tǒng)中的壓力得到釋放，從而達(dá)到對管路及設(shè)備的保護(hù)。

AQ3-1系列閥門是AQ3閥門的改進(jìn)型，它增加了氣動開啟裝置，便于對安全閥及其管路進(jìn)行

CIP清洗。

AQ3安全閥是一種較為特殊的閥門，在出廠時都經(jīng)過了嚴(yán)格的校撿，但為了使閥門能更切合實

際運行工況，故有條件時，應(yīng)盡可能現(xiàn)場對閥門再進(jìn)行校驗。

Safety Valve

Applications:

AQ3 system valve is a sanitary stainless steel safety valve ,its design makes it adequate

For protection of installations in the pharmaceutical industry. lt is used to perform

pressure by pass for safety purposes in order to protect lines, pumps, fittings, tanks, etc.

Operating Principles:

Under normal operating conditions, the valve remains closed .lt is calibrated to a

specific pressure by regulating the spring with the pressure nut. The calibrated

pressure is a maximum safety pressure to avoid damage of the plant.

When the pressure in the circuit exceeds the calibrated pressure, the valve opens

letting the flow pass, thus, the pressure in the pipe system is reduced.

The valve can be provided with a handle ,its designs allows to partially open the valve

in order to allow the passage of the cleaning solutions during the ClP process.
