安裝環(huán)境:蝶閥可在室內(nèi)和室外使用，但在腐蝕性介質(zhì)和易生銹的場合應(yīng)使用相應(yīng)的材料。使用特殊工況可咨詢中致閥。
Installation environment: butterfly valves can be used indoors and outdoors, but corresponding materials shall be used in corrosive media and places prone to rust. Consult Zhongzhi valve for special working conditions.
設(shè)備場所：要安裝在可安全操作、易于維護(hù)、檢查和維護(hù)的場所。
Equipment site: it shall be installed in a place that can be operated safely and easy to maintain, inspect and maintain.
周圍環(huán)境:溫度-20℃~+70℃，濕度低于90%。安裝前，根據(jù)閥門上的銘牌，檢查閥門是否符合工況。注意：蝶閥不具備抗高壓差的能力，不要讓蝶閥在高壓差下打開或持續(xù)流通。
Surrounding environment: temperature - 20 ℃ ~ + 70 ℃, humidity lower than 90%. Before installation, check whether the valve meets the working conditions according to the nameplate on the valve. Note: the butterfly valve does not have the ability to resist high pressure difference. Do not let the butterfly valve open or flow continuously under high pressure difference.
安裝前，請清除管道中的污垢、氧化物等雜物。安裝時請注意，介質(zhì)的流向應(yīng)與閥體上標(biāo)明的流向箭頭一致。
Before installation, please remove dirt, oxides and other sundries in the pipeline. During installation, please note that the flow direction of medium shall be consistent with the flow direction arrow marked on the valve body.
對準(zhǔn)前后管道，使法蘭接口平行，均勻鎖緊螺釘。注意氣動蝶閥不要在氣缸控制閥上產(chǎn)生過大的配管應(yīng)力。根據(jù)氣缸控制閥的大小和重量，在配管上或?qū)Ρ倔w進(jìn)行適當(dāng)?shù)闹喂潭ā?/div>
Align the center of the front and rear pipes, make the flange interface parallel, and lock the screws evenly. Note that the pneumatic butterfly valve shall not produce excessive piping stress on the cylinder control valve. According to the size and weight of the cylinder control valve, properly support and fix the pipe or the body.
維護(hù)注意事項(xiàng)。
Maintenance precautions.
日常檢查:檢查泄漏、異常噪音、振動等。
Daily inspection: check for leakage, abnormal noise, vibration, etc.
定期檢查:定期檢查閥門等系統(tǒng)部件是否有泄漏、腐蝕和堵塞，并進(jìn)行維護(hù)、清潔和除塵、去除殘留污漬等。
Regular inspection: regularly check whether the valve and other system components have leakage, corrosion and blockage, and carry out maintenance, cleaning, dust removal, removal of residual stains, etc.
分解檢查:閥門應(yīng)定期分解檢修。分解檢修時，應(yīng)重新沖洗零件，清除異物、污漬和銹斑，更換損壞或磨損嚴(yán)重的墊片和填料，并修正密封面。檢修后，閥門應(yīng)重新進(jìn)行水壓試驗(yàn)，合格后才能重新使用。
Disassembly inspection: the valve shall be disassembled and overhauled regularly. During disassembly and maintenance, parts shall be flushed again, foreign matters, stains and rust spots shall be removed, gaskets and fillers damaged or seriously worn shall be replaced, and sealing surfaces shall be corrected. After maintenance, the valve shall be subject to hydrostatic test again and can be reused only after passing the test.
如果在檢查氣動蝶閥時發(fā)現(xiàn)流體泄漏，在確認(rèn)安全性之前，請不要用手接觸或靠近氣缸控制閥。
If fluid leakage is found when checking the pneumatic butterfly valve, please do not touch or approach the cylinder control valve by hand until the safety is confirmed.
