丹富斯多功能水泵控制阀产品概述:

阀门的总体尺寸与普通逆止阀相当，由主阀和外装附件组成。其中，主阀包括阀体、压板及膜片、大阀板、缓闭阀板、阀座、阀杆组件等部件。缓闭阀板用阀杆组件与压板及膜片连接一起，膜片压紧在阀盖与膜片座之间，膜片的上下运动带动缓闭阀板上下升降。阀杆穿过大阀板的中心孔，因之大阀板可以在一定的范围内沿阀杆滑动。平时，大阀板在自重压紧在阀座上，使阀门处于关闭状态。多功能水泵控制阀的外装附件安装在阀门膜片两侧与阀门进、出水管上，膜片的下腔与阀门进水侧的连接管上装设控制阀、过滤器和一只特制的逆止阀。多功能水泵控制阀价格及介绍

膜片的上腔与阀门的出水侧的连接管上只设过滤器和一只控制阀。多功能水泵控制阀价格及介绍主阀内大阀板和缓闭阀板的运动和所处的位置决定了阀门工作状态的变化和启闭。阀门的外装附件和管路随时把阀门前后的压力变化传递到阀门内由膜片分成的上腔和下腔，控制大阀板和缓闭阀板的运动，并可以通过调整附件改变大阀板与缓闭阀板的运行速度，使阀门的开启与缓闭时间处于规定的范围内。

丹富斯多功能水泵控制阀工作原理

（1）停泵状态，阀板在出口端及隔膜上腔静压作用下全部关闭。

（2）水泵启动时，水压从旁通管传入下腔，主阀板及缓闭阀板在进口端及下腔水压作用下缓慢开启。

（3）在进水端压力作用下，阀板上升到zui大开口状态，开口高度由流量决定。

（4）停泵瞬间，流量及压力突然降低，主阀板在重力作用下开始向下滑落。

（5）当流量接近于零时，主阀被关闭，主阀板上留有泄流孔以减弱水锤冲击力；主阀板上、下形成压力差，阀门出口水压从旁通管进入上腔推动膜片压板，使下腔水排入阀门进口，缓闭阀板开始缓闭。

（6）缓闭阀板*关闭泄流孔，阀门回到停泵初始状态。

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.
