工(gōng)作原理：

Working principle:

  橡(xiang)膠、金屬聯(lián)接器，主要(yào)由松套法(fǎ)蘭，橡膠、金(jin)屬波紋管(guǎn)等部件組(zu)成。管道系(xì)統因環境(jìng)溫度或使(shǐ)用溫度産(chan)生🥵冷縮或(huo)膨脹時，所(suo)産生的力(li)和變形量(liang)、偏移角度(dù)，聯接器都(dou)能很好的(de)補償。能🔞吸(xī)收系統振(zhèn)動，降低系(xi)統噪音🧡，接(jie)頭兩端✌️任(ren)意偏轉，能(néng)自由調節(jie)軸向或橫(héng)向位移等(děng)。

  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(zhǔ)要由閥體(tǐ)、蝶闆、彈簧(huáng)、絞軸及橡(xiàng)膠圈等部(bu)件組🏃‍♂️成。介(jie)質🎯由蝶闆(pan)無簧面進(jìn)入，當兩半(ban)圓形蝶闆(pǎn)在受介質(zhì)壓力超過(guo)彈簧支承(cheng)力後，使蝶(die)闆自行打(dǎ)開，當切斷(duàn)前方介質(zhi)壓力後，蝶(dié)闆在彈簧(huang)壓力及介(jiè)質反壓力(li)㊙️作用下迅(xùn)速關閉。微(wei)阻緩閉止(zhǐ)回閥，蝶闆(pǎn)在彈簧壓(yā)力及介質(zhì)反作😘用力(lì)下觸及液(yè)壓微阻裝(zhuāng)置，随着反(fǎn)作用力增(zēng)大，蝶闆緩(huǎn)緩關閉。風(fēng)道止回閥(fá)，蝶闆在重(zhong)㊙️錘作用力(lì)及介質反(fǎn)作用力下(xia)迅速關閥(fá)。

  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(diào)試：

Installation and regulation

l  安裝前(qián)必需清潔(jié)閥門内腔(qiāng)，不允許有(you)任何雜物(wu)和污垢附(fu)着。

l  法蘭式(shi)連接在安(an)裝時，兩法(fa)蘭間需加(jia)密封墊。對(duì)夾🍓式連接(jie)在🐉安☎️裝時(shi)，在法蘭與(yu)閥體連接(jiē)處需加密(mi)封墊，然後(hòu)均勻擰緊(jǐn)螺栓。

l  止回(huí)閥安裝時(shí)請注意流(liu)向（閥體上(shang)有箭頭标(biāo)明）。

l  安裝時(shí)請調整使(shi)伸縮管伸(shēn)出到伸縮(suo)量的1/2。使用(yòng)一定期限(xiàn)後，需更換(huan)密封圈。

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(ding)貨須知：

Information for order

l  選(xuǎn)用訂貨時(shi)，請參照産(chan)品樣本注(zhù)明産品規(guī)格、型号及(jí)技🙇‍♀️術參數(shu)（使用溫度(dù)，設備工況(kuang)、介質性質(zhì)及工作壓(yā)力🌍等）。

l  表格(gé)中未列的(de)規格、用于(yú)特殊介質(zhi)或其它特(tè)殊要求，請(qing)與我公司(si)銷售部、技(jì)術部聯系(xi)，可為您另(lìng)行設計制(zhi)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.
