工作(zuò)原理：

Working principle:

  橡膠、金屬(shu)聯接器，主要由(you)松套法蘭，橡膠(jiāo)、金屬波紋管等(deng)🍓部件組成。管道(dao)系統因環境溫(wēn)度或使用溫度(du)産生冷縮或膨(peng)脹時，所産生的(de)力和變形量、偏(piān)移角度，聯接♻️器(qi)都能🔴很好的補(bǔ)償。能吸收系👨‍❤️‍👨統(tǒng)振動，降低系統(tǒng)噪音，接頭兩端(duān)任意偏轉，能自(zì)由調節軸向或(huò)橫向位移等。

  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(zhi)回閥，主要由閥(fa)體、蝶闆、彈簧、絞(jiao)軸及橡膠圈等(deng)部件💁組成。介質(zhi)由蝶闆無簧面(mian)進入，當兩半圓(yuan)形蝶闆在受介(jiè)質🚩壓力超過彈(dan)簧支承力後，使(shi)蝶闆自行打開(kai)，當切斷前方介(jiè)質壓力後，蝶闆(pan)在彈簧壓力及(ji)介🔆質反壓力作(zuò)用下迅🙇‍♀️速關閉(bi)。微‼️阻緩閉止回(huí)閥，蝶闆在彈簧(huang)壓力及介質反(fǎn)作用力下觸及(ji)液壓微阻裝置(zhi)，随着反作用力(li)增大，蝶闆緩緩(huǎn)關閉。風道止回(hui)閥❤️，蝶闆在重錘(chuí)作用💞力及介質(zhi)反作用力下迅(xùn)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.

安裝及(jí)調試：

Installation and regulation

l  安裝前必(bi)需清潔閥門内(nèi)腔，不允許有任(rèn)何雜物和污❤️垢(gòu)附着。

l  法蘭式連(lian)接在安裝時，兩(liǎng)法蘭間需加密(mi)封墊。對夾式💁連(lián)接在🐪安裝時，在(zai)法蘭與閥體連(lian)接處需加密封(fēng)墊，然後均勻擰(ning)緊螺栓。

l  止回閥(fá)安裝時請注意(yì)流向（閥體上有(yǒu)箭頭标明）。

l  安裝(zhuang)時請調整使伸(shen)縮管伸出到伸(shēn)縮量的1/2。使用一(yi)定🙇🏻期限後，需更(gèng)換密封圈。

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(huo)須知：

Information for order

l  選用訂貨(huò)時，請參照産品(pin)樣本注明産品(pǐn)規格、型号及技(jì)術參數（使用溫(wēn)度，設備工況、介(jiè)質性質及工作(zuo)壓力等）。

l  表格中(zhong)未列的規格、用(yong)于特殊介質或(huò)其它特殊要求(qiú)，請與我公司銷(xiāo)售部、技術部聯(lian)系，可為您另行(háng)設計制造。

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.
