丹富斯多功能水泵控制閥產品概述:

閥門的總體尺寸與普通逆止閥相當，由主閥和外裝附件組成。其中，主閥包括閥體、壓板及膜片、大閥板、緩閉閥板、閥座、閥桿組件等部件。緩閉閥板用閥桿組件與壓板及膜片連接一起，膜片壓緊在閥蓋與膜片座之間，膜片的上下運動帶動緩閉閥板上下升降。閥桿穿過大閥板的中心孔，因之大閥板可以在一定的范圍內沿閥桿滑動。平時，大閥板在自重壓緊在閥座上，使閥門處于關閉狀態。多功能水泵控制閥的外裝附件安裝在閥門膜片兩側與閥門進、出水管上，膜片的下腔與閥門進水側的連接管上裝設控制閥、過濾器和一只特制的逆止閥。多功能水泵控制閥價格及介紹

膜片的上腔與閥門的出水側的連接管上只設過濾器和一只控制閥。多功能水泵控制閥價格及介紹主閥內大閥板和緩閉閥板的運動和所處的位置決定了閥門工作狀態的變化和啟閉。閥門的外裝附件和管路隨時把閥門前后的壓力變化傳遞到閥門內由膜片分成的上腔和下腔，控制大閥板和緩閉閥板的運動，并可以通過調整附件改變大閥板與緩閉閥板的運行速度，使閥門的開啟與緩閉時間處于規定的范圍內。

丹富斯多功能水泵控制閥工作原理

（1）停泵狀態，閥板在出口端及隔膜上腔靜壓作用下全部關閉。

（2）水泵啟動時，水壓從旁通管傳入下腔，主閥板及緩閉閥板在進口端及下腔水壓作用下緩慢開啟。

（3）在進水端壓力作用下，閥板上升到zui大開口狀態，開口高度由流量決定。

（4）停泵瞬間，流量及壓力突然降低，主閥板在重力作用下開始向下滑落。

（5）當流量接近于零時，主閥被關閉，主閥板上留有泄流孔以減弱水錘沖擊力；主閥板上、下形成壓力差，閥門出口水壓從旁通管進入上腔推動膜片壓板，使下腔水排入閥門進口，緩閉閥板開始緩閉。

（6）緩閉閥板*關閉泄流孔，閥門回到停泵初始狀態。

Dan fuss multifunctional water pump control valve products overview:

The overall size of the valve from ordinary check valve, consist of the main valve and dressing accessories. Among them, the main valve consists of body, pressure plate and diaphragm and valve plate slowly-closing disc, seat, stem component and other components. Slowly closing valve plate together with the valve stem components connected to the pressure plate and diaphragm, diaphragm pressure between the valve cover and the diaphragm seat, up and down movement of the diaphragm drive slowly closing valve plate lifting up and down. Stem through the center of the large valve plate hole, so the valve plate can slide along the stem in a certain range. At ordinary times, the valve plate in the weight on the seat, the valve in the closed state. Multifunctional water pump control valve installed accessories mounted to the valve on both sides of the diaphragm and the valve inlet and outlet pipe, the inferior vena and valve inlet side of the diaphragm of the connecting pipe installed on the control valve, filter, and a special check valve.

The cavity with the valve on the water side of the diaphragm on the connecting pipe of only a filter and a control valve. Large valve plate within the main valve is gentle closing valve plate movement and position determines the change and the status of the valve opening and closing. Valve accessories and outside line pressure changes before and after the valve to the valve at any time by the diaphragm into the cavity and inferior vena, control the movement of the big valve plate gentle closing valve plate, and can be changed by adjusting the accessories large valve plate and the slow speed of closed valve plate, the valve open and slowly-closing time in a specified range.

Dan fuss multifunctional water pump control valve working principle

(1) stop pump, valve plate in the outlet and the diaphragm chamber under the action of static pressure on all closed down.

(2) the pump starts, the pressure from the by-pass pipe into inferior vena, the main valve plate and slow closing valve plate in the inlet side and inferior vena under the action of water pressure slowly open.

(3) under the effect of inlet pressure, the valve plate up to a maximum opening state, opening height is determined by the traffic.

Moment, (4) stop pump flow and pressure suddenly drops, the main valve plate under the action of gravity downward slide.

(5) when the flow is close to zero, the main valve is closed, the main valve plate with discharge hole to decrease water hammer impact; The main valve plate, the formation pressure, water pressure on the by-pass pipe into the valve outlet cavity moves the diaphragm pressure plate, into the valve inlet and water of the inferior vena, start slowly-closing slowly-closing valve plate.

(6) slow closing valve plate fully closed discharge hole of the valve back to stop pump initial state.
