工作原理：

Working principle:

  橡膠(jiāo)、金屬聯接器，主(zhǔ)要由松套法蘭(lán)，橡膠、金屬波紋(wén)管等部件組成(chéng)。管道系統因環(huán)境溫度或使用(yong)溫度産生冷縮(suo)或膨脹時，所産(chan)生的力和變形(xíng)量、偏移角🔴度，聯(lian)接器都能很好(hǎo)的補償。能吸收(shōu)系統振動，降低(dī)系統噪音，接頭(tóu)兩端任意偏轉(zhuan)，能自由調節軸(zhóu)向或橫向位移(yí)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)由閥體、蝶闆、彈(dàn)簧、絞軸及橡膠(jiao)圈等部件組成(cheng)。介質由蝶闆無(wu)簧面進入，當兩(liang)半圓形蝶闆在(zai)受👨‍❤️‍👨介質👌壓力超(chāo)過彈簧📱支承力(li)後，使蝶闆自行(hang)打開，當切斷前(qián)方🥰介質壓力後(hou)，蝶🆚闆在彈簧壓(ya)力及介質反壓(ya)力作用下迅速(su)關閉。微阻緩閉(bi)止💛回閥，蝶闆😍在(zai)彈簧壓力⚽及介(jiè)質反作😍用力下(xia)觸及液壓微阻(zǔ)裝置，随着反作(zuo)用💁力增大，蝶闆(pǎn)緩緩關閉。風道(dao)止回閥，蝶闆在(zai)重👣錘作用力及(ji)介質反作用🌈力(lì)下迅速關閥。

  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(ān)裝及調試：

Installation and regulation

l  安裝(zhuāng)前必需清潔閥(fá)門内腔，不允許(xu)有任何雜物和(he)🤟污垢附着。

l  法蘭(lán)式連接在安裝(zhuang)時，兩法蘭間需(xu)加密封墊。對夾(jia)📐式♈連接在💋安裝(zhuāng)時，在法蘭與閥(fá)體連接處需加(jiā)密封墊，然後均(jun)勻擰緊螺栓。

l  止(zhǐ)回閥安裝時請(qǐng)注意流向（閥體(tǐ)上有箭頭标明(ming)）。

l  安裝時請調整(zheng)使伸縮管伸出(chu)到伸縮量的1/2。使(shǐ)用一定期㊙️限後(hòu)，需更換密封圈(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.
