工作原理：

Working principle:

  橡(xiàng)膠、金屬聯接器(qi)，主要由松套法(fa)蘭，橡膠、金屬波(bo)紋管等部件組(zu)成。管道系統因(yin)環境溫度或使(shǐ)用溫度産生冷(leng)縮🚩或膨脹時，所(suo)産生的力和變(biàn)形量、偏移角度(du)，聯接器都能很(hen)好的補償。能吸(xi)收系統振動，降(jiang)低系統噪音，接(jiē)頭兩端任意偏(piān)轉，能自由調節(jiē)軸向或橫向位(wei)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(zhǔ)要由閥體、蝶闆(pan)、彈簧、絞軸及橡(xiang)膠圈等部件組(zǔ)成。介質由蝶闆(pǎn)無簧面進入，當(dang)兩半圓形蝶闆(pan)在受介質壓力(li)超過彈簧✂️支承(chéng)力後，使蝶闆自(zì)行打開，當切斷(duan)前方介質壓🚩力(lì)後，蝶闆在彈✍️簧(huang)壓力及介😘質反(fǎn)壓力作用下迅(xùn)速關閉。微阻緩(huan)閉止回閥，蝶闆(pǎn)在彈簧壓力🚶及(jí)介質反作用力(lì)下觸及液壓微(wēi)阻裝置，随着反(fǎn)作用力增大，蝶(dié)闆緩緩關閉。風(fēng)道止回閥，蝶闆(pan)在重錘作用力(li)及介質反作用(yòng)力下迅速關閥(fa)。

  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(jié)閥門内腔，不允(yǔn)許有任何雜物(wù)和污垢附🏃🏻‍♂️着。

l  法(fa)蘭式連接在安(ān)裝時，兩法蘭間(jian)需加密封墊。對(duì)夾式連接在🈲安(an)裝時，在法蘭與(yu)閥體連接處需(xu)加密封墊，然後(hòu)均勻擰緊螺栓(shuan)。

l  止回閥安裝時(shi)請注意流向（閥(fa)體上有箭頭标(biāo)明）。

l  安裝時請調(diao)整使伸縮管伸(shēn)出到伸縮量的(de)1/2。使用一定期限(xian)後，需更換密封(feng)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.
