工作(zuo)原理：

Working principle:

  橡膠(jiao)、金屬聯接(jie)器，主要由(you)松套法蘭(lan)，橡膠、金屬(shu)波紋管❤️等(deng)部件組🧡成(cheng)。管道系統(tong)因環境溫(wen)度或使用(yong)溫度産生(sheng)冷縮或膨(peng)脹時，所産(chan)生的力和(he)變形量、偏(pian)移角度，聯(lian)接🛀器都能(neng)很好的補(bu)償。能💯吸收(shou)系統振動(dong)，降低系統(tong)噪音，接頭(tou)兩端任意(yi)偏轉，能自(zi)由調🍓節軸(zhou)向或🌍橫向(xiang)位移等。

  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(zhi)回閥，主要(yao)由閥體、蝶(die)闆、彈簧、絞(jiao)軸及橡膠(jiao)圈等部件(jian)組成。介🈲質(zhi)由蝶闆無(wu)簧面進入(ru)，當兩半圓(yuan)形蝶闆在(zai)受介質壓(ya)力♋超過彈(dan)簧支承力(li)後，使蝶闆(pan)自行打開(kai)，當切斷前(qian)方介質壓(ya)力後，蝶闆(pan)在彈簧壓(ya)力及介👣質(zhi)反壓力🌈作(zuo)用下迅速(su)關閉。微阻(zu)緩閉止回(hui)閥，蝶闆在(zai)彈簧壓力(li)及介質反(fan)作用力下(xia)觸及🈲液壓(ya)微阻裝📱置(zhi)，随着反作(zuo)用🏃🏻力增大(da)，蝶闆緩緩(huan)關閉。風道(dao)止回閥，蝶(die)闆在重錘(chui)作用力及(ji)介質反作(zuo)用力下迅(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)裝及調試(shi)：

Installation and regulation

l  安裝前必(bi)需清潔閥(fa)門内腔，不(bu)允許有任(ren)何雜物和(he)污垢附着(zhe)。

l  法蘭式連(lian)接在安裝(zhuang)時，兩法蘭(lan)間需加密(mi)封墊。對夾(jia)式連接在(zai)安裝時，在(zai)法蘭與閥(fa)體連接處(chu)需加密封(feng)🏃墊，然後均(jun)勻擰緊螺(luo)栓。

l  止回閥(fa)安裝時請(qing)注意流向(xiang)（閥體上有(you)箭頭标明(ming)）。

l  安裝時請(qing)調整使伸(shen)縮管伸出(chu)到伸縮量(liang)的1/2。使用一(yi)定期限後(hou)，需更換密(mi)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.

訂貨(huo)須知：

Information for order

l  選用(yong)訂貨時，請(qing)參照産品(pin)樣本注明(ming)産品規格(ge)、型号及技(ji)術參🧡數（使(shi)用溫度，設(she)備工況、介(jie)質性質及(ji)工作壓力(li)等）。

l  表格中(zhong)未列的規(gui)格、用于特(te)殊介質或(huo)其它特殊(shu)要求，請與(yu)我公司銷(xiao)售部、技術(shu)部聯系，可(ke)為您另行(hang)設計制造(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.
