工作原理：
Working principle:
橡膠(jiāo)、金屬(shǔ)聯接器，主要由松套法蘭，橡膠、金屬波紋管等部件(jiàn)組成。管道系統因環境溫度或使用溫度産(chǎn)生冷縮或(huò)膨(péng)脹時，所産生的(de)力和變形量、偏移角度，聯接器都能很(hěn)好的補償。能吸收系統振動，降低系統噪音，接頭兩端(duān)任意偏轉，能自由調節軸向或橫向位(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(zhǐ)回閥(fá)，主要由閥體、蝶闆、彈(dàn)簧、絞軸及橡膠圈等部件組成。介質由蝶闆無(wú)簧面進入，當兩半圓形蝶闆在受介(jiè)質壓力超過彈簧支(zhī)承力後，使蝶闆自行打開，當切斷前方(fāng)介質壓力後，蝶闆在彈簧壓力及介質反壓力作用下迅速關閉(bì)。微阻緩閉止回(huí)閥，蝶闆在彈簧壓力及(jí)介質反作用力下觸及液壓微阻裝置(zhì)，随着(zhe)反作用力增(zēng)大，蝶闆緩緩關閉。風道止回(huí)閥，蝶闆在重錘作用力及介質(zhì)反作用力下迅速關閥(fá)。
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.
安裝及調試：
Installation and regulation
l 安裝前必需清(qīng)潔閥門内腔，不允許有任何雜物和污垢(gòu)附着。
l 法蘭(lán)式連接(jiē)在安(ān)裝時，兩(liǎng)法蘭間需加密封墊。對夾(jiá)式連接在(zài)安裝時(shí)，在法蘭與閥(fá)體連接處需加密封墊，然後均勻擰緊螺栓。
l 止回閥安裝時請注意(yì)流向(xiàng)（閥體(tǐ)上有箭頭标明）。
l 安裝時請(qǐng)調整使伸縮管伸出(chū)到伸縮量的1/2。使(shǐ)用一定期限後，需更換密封圈。
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.
訂貨須知：
Information for order
l 選用(yòng)訂貨(huò)時，請參照産品樣本注明産品規格、型号及技術參數（使用溫(wēn)度，設備工況、介質(zhì)性質及工作(zuò)壓力等）。
l 表格中未列的規格、用于特殊介質或(huò)其它特殊(shū)要求(qiú)，請與我公司銷售部、技術部聯(lián)系，可為您(nín)另行設計制(zhì)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.
