工作原(yuan)理：

Working principle:

  橡膠、金(jin)屬聯接器(qì)，主要由松(sōng)套法蘭，橡(xiàng)膠、金屬波(bō)紋管等❗部(bù)件組🌍成。管(guǎn)道系統因(yin)環境溫度(dù)或使用溫(wēn)度産生冷(leng)縮或膨脹(zhang)時🔴，所産🏃‍♀️生(sheng)的力和變(bian)形量、偏移(yí)角度，聯接(jiē)器都能很(hěn)好的補償(cháng)。能吸收系(xi)統振動，降(jiang)低系統噪(zào)音，接頭兩(liang)端任意偏(pian)轉，能自由(you)調節軸向(xiang)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(hui)閥，主要由(you)閥體、蝶闆(pǎn)、彈簧、絞軸(zhou)及橡膠圈(quan)等部♊件組(zu)成。介🔴質👌由(you)蝶闆無簧(huang)面進入，當(dāng)兩半圓形(xíng)蝶闆在受(shòu)介質📐壓力(li)超過彈簧(huáng)支承力後(hòu)，使蝶闆自(zi)行打開，當(dāng)切斷前方(fāng)介質壓力(li)後，蝶闆在(zài)彈簧壓力(lì)及介💃質反(fǎn)壓力作用(yòng)下迅💞速關(guān)閉。微阻緩(huan)閉止回閥(fa)，蝶闆⛹🏻‍♀️在彈(dan)簧壓力📐及(ji)介質反作(zuò)用力下觸(chu)及液壓微(wēi)阻裝🏒置，随(sui)着反作用(yòng)力增大，蝶(dié)闆緩💋緩關(guān)閉。風道止(zhǐ)回閥，蝶闆(pǎn)在重錘作(zuò)用力及介(jie)質反作用(yong)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(zhuang)及調試：

Installation and regulation

l  安(an)裝前必需(xū)清潔閥門(mén)内腔，不允(yǔn)許有任何(hé)雜物和污(wū)垢附着。

l  法(fǎ)蘭式連接(jie)在安裝時(shi)，兩法蘭間(jian)需加密封(fēng)墊。對夾式(shi)連接在安(an)裝時，在法(fa)蘭與閥體(ti)連接處需(xu)加密封墊(nian)，然後均勻(yún)擰緊螺🌈栓(shuan)。

l  止回閥安(an)裝時請注(zhù)意流向（閥(fa)體上有箭(jiàn)頭标明）。

l  安(ān)裝時請調(diao)整使伸縮(suo)管伸出到(dao)伸縮量的(de)1/2。使用一定(ding)期限後，需(xu)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(xū)知：

Information for order

l  選用訂(ding)貨時，請參(cān)照産品樣(yang)本注明産(chǎn)品規格、型(xíng)号及技術(shu)參數（使用(yòng)溫度，設備(bei)工況、介質(zhì)性質及工(gong)作壓力等(děng)）。

l  表格中未(wei)列的規格(gé)、用于特殊(shū)介質或其(qi)它特殊要(yào)求，請與我(wo)公司銷售(shòu)部、技術部(bu)聯系，可為(wéi)您另行設(shè)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.
