工作(zuo)原理(li)：

Working principle:

  橡膠(jiao)、金屬(shu)聯接器，主(zhu)要由松(song)套法蘭(lan)，橡膠(jiao)、金屬(shu)波紋(wen)管等部(bu)件組成(cheng)。管道系統因環(huan)境溫(wen)度(du)或(huo)使用溫度(du)産生(sheng)冷縮(suo)或膨(peng)脹(zhang)時(shi)，所産(chan)生的力(li)和變形(xing)量、偏移(yi)角(jiao)度，聯(lian)接器都能(neng)很好(hao)的補(bu)償。能(neng)吸收系統(tong)振(zhen)動，降低(di)系統噪(zao)音，接頭兩端(duan)任(ren)意(yi)偏轉(zhuan)，能自由調(diao)節軸(zhou)向或(huo)橫向位移(yi)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(zhi)回閥(fa)，主要(yao)由閥體、蝶闆、彈(dan)簧、絞(jiao)軸(zhou)及(ji)橡膠圈等(deng)部件組成(cheng)。介質由蝶闆無(wu)簧面(mian)進入，當兩(liang)半圓(yuan)形蝶闆在(zai)受介質(zhi)壓力超(chao)過彈簧支(zhi)承力(li)後，使(shi)蝶(die)闆自行(hang)打開，當切斷前(qian)方介(jie)質壓(ya)力後(hou)，蝶闆(pan)在彈簧壓(ya)力及介(jie)質(zhi)反壓(ya)力作(zuo)用(yong)下迅速關閉。微(wei)阻緩閉(bi)止回閥，蝶(die)闆在(zai)彈簧(huang)壓力(li)及介(jie)質反作用(yong)力下(xia)觸及液壓微阻(zu)裝置，随着(zhe)反作用力增大(da)，蝶闆(pan)緩緩關閉。風道(dao)止回(hui)閥(fa)，蝶闆在(zai)重錘(chui)作用力及介質(zhi)反(fan)作用力(li)下迅速關(guan)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(ji)調試：

Installation and regulation

l  安裝(zhuang)前必(bi)需清潔閥門内腔，不允許(xu)有任何雜(za)物和(he)污垢(gou)附(fu)着。

l  法蘭(lan)式連接(jie)在(zai)安裝時，兩(liang)法蘭間需(xu)加密封墊(nian)。對夾式連(lian)接(jie)在安裝(zhuang)時，在法蘭(lan)與閥體連(lian)接處需加(jia)密封(feng)墊(nian)，然(ran)後均(jun)勻擰(ning)緊(jin)螺栓。

l  止(zhi)回閥安裝(zhuang)時請注意流向（閥體(ti)上有(you)箭(jian)頭(tou)标明(ming)）。

l  安裝(zhuang)時請調整(zheng)使伸縮(suo)管伸出(chu)到伸(shen)縮量的1/2。使(shi)用一定(ding)期限後(hou)，需更(geng)換密(mi)封圈(quan)。

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(huo)須(xu)知(zhi)：

Information for order

l  選用(yong)訂貨(huo)時，請參照(zhao)産品樣本(ben)注明(ming)産品(pin)規格(ge)、型号(hao)及技術參數（使(shi)用溫度，設備工(gong)況、介質性(xing)質及(ji)工作壓力(li)等）。

l  表(biao)格中(zhong)未列的規(gui)格、用(yong)于特殊介(jie)質或其(qi)它特殊(shu)要求，請與我公(gong)司銷售(shou)部、技術(shu)部聯系，可(ke)為您(nin)另行設計(ji)制造(zao)。

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.
