工作原(yuan)理(li)：

Working principle:

  橡膠(jiao)、金屬(shu)聯接器，主(zhu)要由松(song)套(tao)法蘭，橡膠(jiao)、金屬波紋(wen)管等部(bu)件(jian)組成(cheng)。管道(dao)系統因環(huan)境溫度(du)或(huo)使用溫度(du)産(chan)生(sheng)冷縮(suo)或膨(peng)脹(zhang)時，所産(chan)生的(de)力(li)和(he)變形(xing)量、偏(pian)移(yi)角度，聯(lian)接器(qi)都能(neng)很好(hao)的補償。能吸收系統(tong)振動(dong)，降低(di)系統(tong)噪音(yin)，接頭兩端任意(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.

  止回閥，主要(yao)由閥(fa)體、蝶闆、彈(dan)簧、絞軸及(ji)橡膠(jiao)圈等(deng)部(bu)件(jian)組成(cheng)。介質由蝶闆無簧面進入，當兩(liang)半圓形蝶闆在(zai)受介(jie)質(zhi)壓力超(chao)過彈(dan)簧支(zhi)承力(li)後，使(shi)蝶闆自行(hang)打開(kai)，當切斷前(qian)方介質(zhi)壓力後(hou)，蝶闆在彈(dan)簧壓(ya)力及介(jie)質反壓(ya)力作用下(xia)迅速(su)關閉。微阻(zu)緩閉(bi)止回閥(fa)，蝶(die)闆在彈簧(huang)壓力及介(jie)質反作(zuo)用力下(xia)觸及液(ye)壓微阻(zu)裝置，随着(zhe)反作用力(li)增大，蝶闆(pan)緩緩關閉。風道止回(hui)閥，蝶闆在(zai)重錘作(zuo)用(yong)力及(ji)介質反作用力(li)下迅(xun)速關閥。

  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(an)裝及(ji)調(diao)試：

Installation and regulation

l  安裝(zhuang)前必(bi)需(xu)清(qing)潔閥(fa)門内(nei)腔，不允許(xu)有任(ren)何雜(za)物和(he)污垢(gou)附(fu)着。

l  法蘭(lan)式連接(jie)在(zai)安裝(zhuang)時，兩(liang)法蘭間需(xu)加密(mi)封墊(nian)。對夾(jia)式連(lian)接在(zai)安裝(zhuang)時，在法(fa)蘭(lan)與閥(fa)體連(lian)接處(chu)需加(jia)密封(feng)墊，然(ran)後均勻擰緊螺栓。

l  止(zhi)回閥安裝時請(qing)注意(yi)流向（閥體(ti)上有箭頭(tou)标明(ming)）。

l  安裝(zhuang)時(shi)請(qing)調整(zheng)使伸縮管伸出到伸縮(suo)量(liang)的1/2。使(shi)用一(yi)定期限後(hou)，需更(geng)換密封圈(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.

訂貨須知：

Information for order

l  選用(yong)訂貨(huo)時，請參照(zhao)産品(pin)樣本注明(ming)産品(pin)規格、型号(hao)及技術(shu)參數（使用溫(wen)度，設備工(gong)況、介質(zhi)性質及工作(zuo)壓力等）。

l  表(biao)格中未(wei)列的規(gui)格、用(yong)于特殊介(jie)質或(huo)其它特殊要求(qiu)，請與(yu)我公(gong)司銷售(shou)部(bu)、技術(shu)部聯系(xi)，可為您(nin)另行(hang)設(she)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.
