工(gong)作原理：

Working principle:

  橡膠、金(jīn)屬聯接器，主要(yao)由松套法蘭，橡(xiàng)膠、金屬波紋管(guan)等部💜件組🆚成。管(guǎn)道系統因環境(jìng)溫度或使用溫(wēn)度産生冷縮或(huò)膨脹時，所産㊙️生(sheng)的力和變形量(liang)、偏移角度，聯接(jiē)器都能很好的(de)補償。能吸收系(xì)統振動，降低系(xì)統噪音，接頭兩(liǎng)端🌈任意偏轉，能(néng)自由調節軸向(xiàng)或橫向位移等(deng)。

  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，主要由(you)閥體、蝶闆、彈簧(huang)、絞軸及橡膠圈(quan)等部件🌈組🈲成。介(jiè)質由蝶闆無簧(huang)面進入，當兩半(bàn)圓形蝶闆在受(shou)介質壓力超過(guo)彈簧支承力後(hòu)，使蝶闆自行打(da)㊙️開，當切斷前方(fāng)介質壓力後，蝶(die)闆在彈簧壓力(li)及介質反壓力(li)作用下迅速關(guān)閉。微阻緩閉止(zhǐ)回閥，蝶闆在彈(dàn)簧壓力及介質(zhi)反作用力下觸(chu)及液壓微阻裝(zhuāng)置，随着反作用(yòng)力增大，蝶闆緩(huan)緩關閉。風道止(zhǐ)回閥，蝶闆在重(zhong)錘作用力及介(jie)質反作用🐉力下(xia)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.

安裝(zhuāng)及調試：

Installation and regulation

l  安裝前(qián)必需清潔閥門(mén)内腔，不允許有(yǒu)任何雜物和污(wū)垢附着。

l  法蘭式(shì)連接在安裝時(shí)，兩法蘭間需加(jiā)密封墊。對夾式(shì)連接在安裝時(shi)，在法蘭與閥體(tǐ)連接處需加密(mi)封㊙️墊，然後均勻(yún)擰💛緊螺栓。

l  止回(huí)閥安裝時請注(zhu)意流向（閥體上(shàng)有箭頭标明）。

l  安(an)裝時請調整使(shi)伸縮管伸出到(dào)伸縮量的1/2。使用(yong)一定期限後，需(xū)更換密封圈。

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(dìng)貨須知：

Information for order

l  選用訂(dìng)貨時，請參照産(chan)品樣本注明産(chǎn)品規格、型号及(ji)💁技術參💛數（使用(yong)溫度，設備工況(kuang)、介質性質及工(gong)作壓力等）。

l  表格(gé)中未列的規格(ge)、用于特殊介質(zhì)或其它特殊要(yào)求，請與我公司(si)銷售部、技術部(bù)聯系，可為您另(ling)行設計制造。

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.
