工作(zuò)原理：

working principle:

  橡膠、金屬(shǔ)聯(lián)接器，主(zhǔ)要由松套法蘭(lán)，橡膠、金屬波紋(wén)管等(děng)部件組成(chéng)。管道系統因環(huán)境溫度或使(shǐ)用溫度(dù)産生(shēng)冷縮(suō)或膨脹(zhàng)時(shí)，所産(chǎn)生的(de)力和變形(xíng)量、偏移角度，聯(lián)接器都能很好(hǎo)的補(bǔ)償。能(néng)吸收(shōu)系統振(zhèn)動，降低(dī)系統噪(zào)音(yīn)，接頭(tóu)兩端(duān)任意偏轉(zhuǎn)，能自由(yóu)調節軸(zhóu)向或橫(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.

  止回閥，主要(yào)由閥(fá)體、蝶闆、彈(dàn)簧、絞軸及橡膠圈等(děng)部件組成。介質由蝶(dié)闆無簧面進(jìn)入(rù)，當兩半圓形(xíng)蝶(dié)闆在(zài)受介(jiè)質壓(yā)力超(chāo)過彈(dàn)簧支承力後，使蝶(dié)闆自行(háng)打開，當(dāng)切斷前(qián)方介(jiè)質(zhì)壓(yā)力後，蝶闆在彈簧壓(yā)力及介質(zhì)反壓(yā)力作用下迅速(sù)關閉(bì)。微阻(zǔ)緩閉(bì)止回閥(fá)，蝶闆在彈簧壓力(lì)及介(jiè)質反作用力(lì)下觸及液壓(yā)微阻裝置，随(suí)着(zhe)反作(zuò)用力(lì)增大(dà)，蝶闆(pǎn)緩(huǎn)緩關閉(bì)。風道(dào)止回(huí)閥，蝶闆在重錘作用(yòng)力及(jí)介質(zhì)反作用力(lì)下迅速關(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(ān)裝及(jí)調試(shì)：

installation and regulation

l  安裝(zhuāng)前必需清潔(jié)閥(fá)門内腔，不允許(xǔ)有任(rèn)何(hé)雜物和污垢(gòu)附(fù)着。

l  法蘭(lán)式連(lián)接在安裝(zhuāng)時，兩(liǎng)法蘭間需(xū)加密封墊。對夾(jiá)式連(lián)接在安裝(zhuāng)時，在法蘭(lán)與閥(fá)體(tǐ)連接處需加(jiā)密封(fēng)墊，然(rán)後均(jun1)勻擰緊螺(luó)栓。

l  止(zhǐ)回閥安(ān)裝(zhuāng)時請注意(yì)流向（閥體(tǐ)上有(yǒu)箭(jiàn)頭标明(míng)）。

l  安裝(zhuāng)時(shí)請調整(zhěng)使伸縮管(guǎn)伸出到伸縮量的1/2。使(shǐ)用一(yī)定期限後(hòu)，需更換密封圈(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：

information for order

l  選用(yòng)訂貨時，請參照(zhào)産品(pǐn)樣本注明産品(pǐn)規格、型号(hào)及技術(shù)參數（使(shǐ)用溫(wēn)度，設備工(gōng)況、介(jiè)質性(xìng)質及(jí)工作(zuò)壓力等）。

l  表(biǎo)格中未列的規(guī)格、用于特殊介(jiè)質或其它(tā)特(tè)殊要求(qiú)，請與(yǔ)我公司銷售(shòu)部、技術部聯系(xì)，可為您(nín)另行設計制造(zào)。

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.
