工作原理：

Working principle:

  橡(xiàng)膠、金屬聯接(jie)器，主要由松(song)套法蘭，橡膠(jiāo)、金屬波紋管(guǎn)🔴等部件組🔴成(chéng)。管道系統因(yīn)環境溫度或(huo)使用溫度♍産(chan)生冷縮或膨(péng)脹時，所産生(sheng)的力和變形(xing)量、偏移角度(du)，聯接器都能(neng)很好的補償(chang)。能吸收系統(tong)振動，降低系(xi)統噪音，接頭(tou)兩端任意偏(pian)轉㊙️，能自由調(diào)節軸向或橫(heng)向位移等。

  The rubber, metal connector is mainly made up of free flange, rubber and metal ripple pipe etc. The system pipe contracts or expands because of environment temperature or using temperature. The connector can compensate the force, distortion amount and excursion angle, which is made by contracting or expanding. It can absorb system quiver and reduce system noise. The joint ends can be deflected arbitrarily and adjust shaft freely.

  止(zhǐ)回閥，主要由(yóu)閥體、蝶闆、彈(dàn)簧、絞軸及橡(xiang)膠圈等部件(jiàn)組成。介質✍️由(you)蝶闆無簧面(miàn)進入，當兩半(ban)圓形蝶闆在(zài)受介質壓力(lì)超過彈簧支(zhī)承力後，使蝶(dié)闆自行打開(kāi)，當切斷前方(fang)介質壓力後(hou)，蝶闆在彈簧(huang)壓力及介質(zhi)反壓力作用(yòng)下迅💃速關閉(bì)。微阻緩閉止(zhi)回閥，蝶闆🌈在(zài)彈簧壓力及(jí)介質反作用(yong)力下觸及液(yè)壓微阻裝🤞置(zhì)，随着反作💃用(yòng)力增大，蝶闆(pan)緩緩關閉。風(fēng)道止💘回閥，蝶(dié)闆在重錘作(zuo)用力及介質(zhì)反作用👄力下(xià)迅速關閥。

  The check valve is mainly made up of valve body, butterfly board, spring, wring shaft and rubber ring etc. the medium enter from butterfly board which is without spring. When medium pressure of the two round butterfly boards is beyond the spring bearing, the board will open itself. When cut off the medium pressure ahead, the board will close quickly on the effect of spring pressure and medium counterforce. The board of micro-block slow-close check valve touches the hydraulic micro-block device on the effect of spring pressure and medium anti-pressure. The board closes slowly as the counterforce increasing. The board of venting pipe check valve close quickly on the effect of hammer force and medium counterforce.

安(ān)裝及調試：

Installation and regulation

l  安(an)裝前必需清(qing)潔閥門内腔(qiang)，不允許有任(ren)何雜物和☀️污(wu)垢附😍着。

l  法蘭(lán)式連接在安(an)裝時，兩法蘭(lán)間需加密封(fēng)墊。對夾式連(lián)接在📞安裝時(shí)，在法蘭與閥(fa)體連接處需(xu)加密封墊，然(ran)🔞後均勻擰緊(jin)螺栓。

l  止回閥(fa)安裝時請注(zhù)意流向（閥體(ti)上有箭頭标(biāo)明）。

l  安裝時請(qǐng)調整使伸縮(suo)管伸出到伸(shēn)縮量的1/2。使用(yong)一定期限後(hòu)，需更換密封(feng)圈。

l   The body must be cleaned before installed and there is no dirt and sundries clinging to the body.

l   Add seal cushion between two flanges of flange type connection or between the flange and valve body of dual clamp type connection, then screw down bolt when installs the valve.

l   Pay attention to the flow direction of check valve when install. There is arrow on the valve body.

l   Extend the pipe to the 1/2 of extension amount when install the extension pipe. Seal rings need to be exchanged after the steel extension pipe has been used for a period of time limit.

訂貨須知(zhī)：

Information for order

l  選用訂貨時(shí)，請參照産品(pǐn)樣本注明産(chǎn)品規格、型号(hào)及技術參數(shù)（使用溫度，設(shè)備工況、介質(zhì)性質及工作(zuo)壓力等）。

l  表格(gé)中未列的規(guī)格、用于特殊(shū)介質或其它(tā)特殊要求，請(qing)與我公司銷(xiao)售部、技術部(bu)聯系，可為您(nín)另行設計制(zhi)造。
