工作原理(lǐ)：

Working principle:

  橡膠、金屬(shu)聯接器，主(zhu)要由松套(tào)法蘭，橡膠(jiao)、金屬波紋(wén)🌈管等🐇部件(jian)組成。管道(dao)系統因環(huán)境溫度或(huo)使用溫度(du)産生冷縮(suō)或膨脹時(shi)，所産🔞生的(de)力和變形(xing)量、偏移角(jiao)度，聯接器(qì)都能很好(hǎo)的補償。能(neng)吸收系統(tǒng)振動，降低(dī)系統噪音(yīn)，接頭兩端(duan)任意偏轉(zhuǎn)，能自由調(diào)節軸向或(huo)⛹🏻‍♀️橫向位移(yi)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.

  止回閥(fá)，主要由閥(fá)體、蝶闆、彈(dan)簧、絞軸及(jí)橡膠圈等(děng)部件組成(chéng)。介質由蝶(die)闆無簧面(miàn)進入，當兩(liǎng)半圓形蝶(die)闆在受🛀🏻介(jiè)質壓力超(chao)過彈簧支(zhi)承力後，使(shǐ)蝶闆自行(hang)打開，當切(qie)斷前方介(jiè)質壓力後(hou)，蝶闆在彈(dan)🙇🏻簧壓力及(jí)介質反壓(yā)力作用下(xia)迅速關閉(bi)。微阻緩閉(bì)止㊙️回閥，蝶(die)闆在彈簧(huáng)壓力📞及介(jie)質反作👨‍❤️‍👨用(yong)力下觸及(jí)‼️液壓微阻(zǔ)裝👌置，随着(zhe)反作用力(li)增大，蝶闆(pǎn)緩緩關閉(bì)。風道止回(huí)閥，蝶闆在(zài)重🛀🏻錘作用(yòng)😄力及介質(zhi)反作用力(lì)下迅速關(guān)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.

安裝及(ji)調試：

Installation and regulation

l  安裝(zhuāng)前必需清(qing)潔閥門内(nei)腔，不允許(xǔ)有任何雜(zá)物和污🥰垢(gou)附✉️着。

l  法蘭(lan)式連接在(zai)安裝時，兩(liǎng)法蘭間需(xu)加密封墊(nian)。對夾式連(lian)接在安裝(zhuāng)時，在法蘭(lan)與閥體連(lian)接處需加(jiā)密封🔅墊，然(rán)後均🔅勻擰(nǐng)緊螺栓。

l  止(zhi)回閥安裝(zhuāng)時請注意(yì)流向（閥體(tǐ)上有箭頭(tou)标明）。

l  安裝(zhuāng)時請調整(zheng)使伸縮管(guan)伸出到伸(shēn)縮量的1/2。使(shi)用一定期(qī)限✍️後，需🛀🏻更(geng)換密封圈(quan)。

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(zhi)：

Information for order

l  選用訂貨(huò)時，請參照(zhao)産品樣本(ben)注明産品(pin)規格、型号(hào)及技術參(cān)☂️數（使用溫(wēn)度，設備工(gong)況、介質性(xing)質及工作(zuò)壓力等）。

l  表(biǎo)格中未列(liè)的規格、用(yong)于特殊介(jiè)質或其它(ta)特殊要求(qiú)，請與我公(gong)司銷售部(bu)、技術部聯(lián)系，可為您(nin)另行設計(jì)制造。

l   Please indicate the type, model and technical parameter (using temperature, working condition of equipment and characteristic of medium etc) referring to the product sample when you place an order

l  If you have other special demand, need special medium or the spec that is not listed in the table, please contact with our department of market and technology. We can design and manufacture for you especially.
