雙向調節(jié)插板閥是近年來綜合使用插板閥的經驗設計制造的，主要用于通風除塵、風力輸送及排風系統(tǒng)管路上的調節(jié)和固體粉料輸送的調節(jié)和切斷。

This series valve is designed basing on the experience of using inserting disc valve. It is mainly used to regulate in pipes of venting removing dust, carrying, venting system and to regulate or cutting carrying of solid powder.

雙向調節(jié)插板閥結構特點：

Structure characteristic:

采用優(yōu)質鋼材焊接而成，具有結構簡單，操作自如，閥板滑動靈活，密閉性能優(yōu)良等特點。局部阻力損失小，調節(jié)性能好，維護保養(yǎng)拆卸方便，不易變形，克服了老式插板閥漏風大、變形快、調節(jié)困難的毛病。特別適用于無粘度的固體粉料及小于 Φ 10mm 顆粒料、晶體料、固狀物料的輸送。

This valve is welded in fine steel and simple in structure, handy to operate, smooth to slide, good in seal. Especially it is less loss in local resistance, good regulation, convenient to replace and maintain, not distorted. It overcomes the defect of outdated inserting disc valve such as great leakage, distorting quickly and difficulty in regulating. It is suitable to transport non-glutinosity solid powder and grain, crystalloid, solid material less than 10mm.

雙向調節(jié)插板閥工作原理：

Working principle:

手動密閉閘閥主要由把手、閥體、插板、鎖緊螺釘、密封裝置等部件組成。運行時先松開鎖緊螺釘，手握把手向外抽出，達到工況開啟任意位置，然后擰緊鎖緊螺釘，使插板停留在這一位置。反之則關閉插板閥（向內推進）。

The valve is mainly made up of handle, body, disc, locknut and seal etc. Loosen locknut and draw out the handle to open random position when operate. Then screw down locknut to make the disc settled in this position. Otherwise close disc.

雙向調節(jié)插板閥使用說明：

Operation instruction:

•  本閥連接方式為法蘭連接。

•  本閥可水平或垂直安裝，安裝時兩法蘭聯(lián)接中間必須加密封墊片，然后均勻鎖緊螺栓。

•  手動操作時向外抽出為開，向內推進為關。不得在把手上增加輔助器材。

•  若長期存放應使設備處于關閉狀態(tài)，各傳動部位應加潤滑油，不允許露天存放或堆置。

•  Joint type of this valve is flange joint.

•  The valve can be installed in horizontal or vertical. Add seal cushion between two flanges connection and screw down bolt.

•  Draw out handle means open and push in means close. Assistant lever can't be added to handle.

•  Add lubricant to transmission part when valve is long stored. It should not be placed or piled up in the open air.
