工作原(yuán)理：

working principle:

  橡膠(jiāo)、金屬聯(lián)接器(qì)，主要由松套(tào)法蘭，橡膠、金(jīn)屬波紋(wén)管等(děng)部件(jiàn)組成。管道(dào)系統因環(huán)境溫度(dù)或使(shǐ)用(yòng)溫度産生冷縮(suō)或膨脹(zhàng)時，所産(chǎn)生的(de)力(lì)和變形(xíng)量、偏移角(jiǎo)度，聯(lián)接器都能很(hěn)好的補償。能(néng)吸收系統振(zhèn)動(dòng)，降低(dī)系統(tǒng)噪音，接頭兩端(duān)任意偏轉(zhuǎn)，能自由調節(jiē)軸(zhóu)向或(huò)橫(héng)向(xiàng)位移(yí)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(huí)閥，主要(yào)由閥(fá)體(tǐ)、蝶闆、彈(dàn)簧、絞軸及橡膠圈等(děng)部件(jiàn)組成(chéng)。介質由蝶闆無(wú)簧面進入(rù)，當兩(liǎng)半圓形蝶闆在受(shòu)介質壓力超(chāo)過彈簧支承(chéng)力後，使(shǐ)蝶闆自行打開(kāi)，當切斷前(qián)方介(jiè)質壓力後(hòu)，蝶闆在彈(dàn)簧壓力及介質反(fǎn)壓力作用下迅速(sù)關閉。微阻緩閉(bì)止回閥，蝶闆在彈(dàn)簧壓(yā)力及介(jiè)質反作用力(lì)下觸及(jí)液(yè)壓(yā)微阻(zǔ)裝置(zhì)，随(suí)着反作(zuò)用力(lì)增大，蝶闆(pǎn)緩緩關閉。風道止回閥，蝶闆(pǎn)在(zài)重錘作用(yòng)力及(jí)介質反(fǎn)作用力(lì)下迅(xùn)速關(guān)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(jí)調試：

installation and regulation

l  安裝(zhuāng)前必需清潔閥門内腔，不(bú)允許有任何雜(zá)物和(hé)污垢附着。

l  法蘭(lán)式連接在安裝(zhuāng)時，兩法(fǎ)蘭間需(xū)加密封墊(niàn)。對夾式連(lián)接(jiē)在安裝時，在法蘭與閥體連接處需加(jiā)密封墊，然(rán)後均(jun1)勻擰緊螺(luó)栓。

l  止(zhǐ)回閥安裝(zhuāng)時請注意(yì)流向(xiàng)（閥體(tǐ)上(shàng)有箭頭标明）。

l  安裝(zhuāng)時請調整(zhěng)使伸縮管伸出(chū)到伸(shēn)縮(suō)量的1/2。使(shǐ)用一定期限後(hòu)，需(xū)更換密封圈(quān)。

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(zhī)：

information for order

l  選用(yòng)訂貨時，請(qǐng)參照(zhào)産品樣(yàng)本注明(míng)産品(pǐn)規格、型号(hào)及技術參數（使(shǐ)用溫(wēn)度，設備工(gōng)況、介質性質及(jí)工作(zuò)壓力等）。

l  表(biǎo)格中(zhōng)未(wèi)列的規格(gé)、用于特殊介(jiè)質或其(qí)它(tā)特殊(shū)要求，請與我公司銷(xiāo)售(shòu)部、技術部聯(lián)系，可為您另行設計制造。

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.
