工作(zuo)原理：

Working principle:

  橡膠、金屬聯(lián)接器，主要由松套(tao)法蘭，橡膠、金屬波(bo)紋‼️管等部件組成(chéng)。管道系統因環境(jing)溫度或使用溫度(dù)産生冷縮或膨🚶脹(zhàng)時，所産生的力和(he)變形量、偏移角度(dù)，聯接器都能💔很好(hao)的🈲補償。能吸收系(xì)🥰統振動，降低系統(tǒng)噪音💯，接頭兩端任(rèn)意偏轉，能自由調(diào)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.

  止回閥，主要(yao)由閥體、蝶闆、彈簧(huáng)、絞軸及橡膠圈等(deng)部件⭕組成。介質由(you)蝶闆無簧面進入(rù)，當兩半圓形蝶闆(pǎn)在受介質壓力超(chao)過彈簧支承力後(hòu)，使蝶闆自行打開(kai)，當切斷前方介質(zhi)壓力後，蝶闆在彈(dan)💔簧壓力及介質反(fǎn)壓力作用下迅速(su)關閉。微阻緩閉止(zhi)回閥，蝶闆在彈簧(huang)壓力及介質反作(zuo)🛀用力下觸及液壓(ya)微阻裝👄置，随着反(fan)作用力增大，蝶闆(pǎn)緩緩關閉。風道止(zhǐ)回閥，蝶闆在重錘(chui)作用力及介質反(fan)作用力下迅速關(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.

安裝及調試：

Installation and regulation

l  安(ān)裝前必需清潔閥(fá)門内腔，不允許有(you)任何雜物和污垢(gou)附着。

l  法蘭式連接(jie)在安裝時，兩法蘭(lán)間需加密封墊。對(duì)夾式連♍接在安💔裝(zhuāng)時，在法蘭與閥體(tǐ)連接處需加密封(fēng)墊，然後均👅勻擰緊(jǐn)螺栓。

l  止回閥安裝(zhuang)時請注意流向（閥(fá)體上有箭頭标明(ming)）。

l  安裝時請調整使(shǐ)伸縮管伸出到伸(shēn)縮量的1/2。使用一💔定(ding)期♊限後，需更換密(mì)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.
