工作(zuò)原理：

Working principle:

  橡膠、金(jin)屬聯接器，主(zhu)要由松套法(fǎ)蘭，橡膠、金屬(shǔ)波紋管等部(bù)件組成。管道(dào)系統因環境(jìng)溫度或使用(yong)溫度産生☁️冷(lěng)縮或膨脹時(shi)，所産✔️生的力(li)和變形量、偏(piān)移角度，聯接(jiē)器都能❓很好(hao)的補償。能吸(xī)收系統振動(dong)，降低系統噪(zào)音，接頭兩端(duān)任意偏轉，能(néng)自由調節軸(zhou)向或橫向位(wèi)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.

  止回閥(fa)，主要由閥體(ti)、蝶闆、彈簧、絞(jiǎo)軸及橡膠圈(quan)等部件組成(chéng)✊。介質由蝶闆(pan)無簧面進入(rù)，當兩半圓形(xíng)蝶闆在受介(jiè)質壓力超過(guo)彈簧支承力(li)後，使蝶闆自(zi)行打開，當切(qie)斷前方介質(zhi)壓力後，蝶闆(pan)在彈🏃簧壓力(lì)及介🙇‍♀️質反壓(ya)力作用下迅(xun)速關閉。微阻(zu)緩閉止回閥(fá)，蝶闆在彈簧(huang)壓力及介質(zhì)反作用力下(xia)觸及液壓微(wēi)阻裝置，随着(zhe)反作用力增(zeng)大，蝶闆緩緩(huǎn)關閉。風道止(zhǐ)回閥，蝶闆在(zai)重🐆錘作用力(li)及介質反作(zuo)用力下迅速(su)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(qián)必需清潔閥(fa)門内腔，不允(yun)許有任何雜(zá)物和污垢附(fu)🎯着。

l  法蘭式連(lián)接在安裝時(shi)，兩法蘭間需(xu)加密封墊。對(duì)夾式🔞連接在(zai)安⛱️裝時，在法(fǎ)蘭與閥體連(lian)接處需加密(mì)封墊，然後均(jun1)勻擰緊螺栓(shuan)。

l  止回閥安裝(zhuāng)時請注意流(liú)向（閥體上有(you)箭頭标明）。

l  安(ān)裝時請調整(zheng)使伸縮管伸(shēn)出到伸縮量(liang)的1/2。使用一✌️定(ding)期限後，需更(geng)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(ding)貨須知：

Information for order

l  選用(yong)訂貨時，請參(cān)照産品樣本(ben)注明産品規(gui)格、型号及技(ji)術㊙️參數（使用(yòng)溫度，設備工(gōng)況、介質性質(zhì)及工作壓力(li)等）。

l  表格中未(wèi)列的規格、用(yong)于特殊介質(zhi)或其它特殊(shū)要求，請與我(wǒ)公司銷售部(bu)、技術部聯系(xi)，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.
