瓣阀

Constant Flow Valve and the constant flow regulating valve are different: there is only one fixed flow valve valve from the valve directly feel before and after the differential pressure valve, the implementation of change in valve resistance action can be "direct action type variable resistance valve "It should not regulate the flow line, so the use of Constant Flow Valve can not be implemented to change the total flow of energy to run, and this set the flow valve as there are no imports of expensive, in the past, domestic heating systems seldom used, and only at some central air conditioning system to see.

定流量阀和恒流量调节阀不同的是：定流量阀只有一个阀瓣，由这个阀瓣直接感受阀门的前后差压，执行改变阀门阻力的动作，可成为"直动式变阻力阀"，它不能在线调节流量，因此使用定流量阀无法实施改变总流量的节能运行，而且这种定流量阀国内没有，进口的价格昂贵，以往国内的供暖系统很少采用，只有在一些中央空调系统中见到。

Constant Flow Valve and the constant flow regulating valve are different:there is only one fixed flow valve valve from the valve directly feel before and after the differential pressure valve,the implementation of change in valve resistance action can be"direct action type variable resistance valve",闸阀;It should not regulate the flow line,so the use of Constant Flow Valve can not be implemented to change the total flow of energy to run,and this set the flow valve as there are no imports of expensive,in the past,domestic heating systems seldom used,and only at some central air conditioning system to see.

订流量阀和恒流量调节阀不同的是：定流量阀只需一个阀瓣，由这个阀瓣直接感受阀门的后后佳压，执行转变阀门阻力的动做，否成为"直动式变阻力阀"，facebook外白板，它没有能在线调节流量，研建课，因己运用定淌量阀无法实施改变合流量的节能运行，而且这种定流量阀海外不，入口的价钱昂贵，以来国内的供暖体系很少采用，只需在一些中央空调系统内见到。

A hinged valve that permits fluids to flow in only one direction and clacks when the valve closes .

瓣阀：一种铰接的阀，只容许流体单向流动，关闭时发出卡嗒声

In order to ensure that the flap valve seat face every time to reach the appropriate position, the valve flap design in the hinge so that the valve flap is enough to swing space, and make a real disc, comprehensive engagement with the valve seat.

为了确保阀瓣每次都能到达阀座面的合适位置，阀瓣设计在铰链机构，以便阀瓣具有足够有旋启空间，并使阀瓣真正的、全面的与阀座接触。

In order to ensure that the flap valve seat face every time to reach a suitable position, the valve flap design in the hinge body to valve flap has enough to swing space, and make High Pressure Steam safety valve a real flap valve, comprehensive engagement with the valve seat.

为了确保阀瓣每次都能到达阀座面的合适位置，阀瓣设计在铰链机构，以便阀瓣具有足够有旋启空间，并使阀瓣真正的、全面的与阀座接触。

Spring-loaded safety valve spring is delivered to the valve on the container or force to balance the pipeline pressure by adjusting the elastic springs to balance the medium on the pressure valve control media pressure to achieve the objective of safety valve lever weights Is to use a heavy hammer through the transmission lever to force the valve to balance the pipe or container medium pressure by adjusting the weights of the valve to balance the role of media from the valve on the pressure, media pressure to achieve the purpose of control ; Pilot of the main safety valve by valve components and sub-valve, to promote the role of Vice valve main valve action, also known as the pulse safety valve.

弹簧式安全阀是利用弹簧传递到阀瓣上的作用力来平衡容器或管道内压，通过调节弹簧的松紧来平衡介质对阀瓣的压力从而达到控制介质压力的目的；杠杆重锤式安全阀是利用重锤通过杠杆传递到阀瓣上的作用力来平衡管道或容器内介质的压力，通过调整重锤对阀瓣的作用距离来平衡介质对阀瓣的压力，从而达到控制介质压力的目的；先导式安全阀是由主阀和副阀组成，借副阀的作用带动主阀动作，又称为脉冲式安全阀。

The cut-off valve with pilot valve without hand wheel, stem and lift nut inside will guide block and guide slot Butterfly Valves to guide sleeve, the disc-shaped disc to disc type bowl shape, and holes in the bottom of the flap valve to open, the valve cover of the original valve stem hole to hole diversion, because of increased pressure ring, ring, and the valve flap to class mortar, so that the flow passage separated the upper chamber cavity, external cavity, cavity, in the cavity and The external cavity increases with draft tube and stainless steel manual ball valve, flap valve in the cover plate and the center of the end of installing the spring, the upper flap valve install compression seal of the pressure ring, outside the cavity of the wall to open a Drainage holes.

带先导球阀的截止阀无手轮、阀杆和内升降螺母，将导向块与导向槽改为导向套，将盘形阀瓣改为类钵体形阀瓣，并在底部开阀瓣孔，电动蝶阀将阀盖原阀杆孔改为导流孔，因增加压环、密封圈和将阀瓣改为类钵体，使上通流腔分隔为上腔、外腔、内腔，在上腔与外腔的外部加设有导流管与不锈钢手动球阀，在盖板与阀瓣底的中心部加设弹簧，阀瓣上部加设压紧密封圈的压环，在外腔的壁上开有放水孔。

In addition to this valve disc is free to lift, the other part of the same as the cut-off valve, the fluid pressure valve from the valve seat sealing surface of valve lift, medium return A42C Type Pound-Grade Low Lift Spring Loaded Safety Valve led to a seat on the disc down and cut off the flow.

此阀门除了阀瓣可以自由地升降之外，其余部分如同截止阀一样，流体压力使阀瓣从阀座密封面上抬起，介质回流导致阀瓣回落到阀座上，并切断流动。

2 The provisions of valve flap stent thrust nut in space; 4.3 will bring more than ejector stem components, and into the valve flap bracket, now can adjust screw ring on the injector; adjustment ring discharge pipe may be twisted too high in case of this case, when the valve assembly after the valve flap in contact with its seat before the valve flap seat will have an additional load on the adjustment ring edge, in order to avoid this from happening, should enable the adjustment ring hole just below the injector thread, through which holes should not be able to see thread.

4.2 规定阀瓣支架与止推螺母中的间隙； 4.3 将喷射器提起超过阀杆组件，并放到阀瓣支架上，现在可以把调节环拧在喷射器上；调节环可能在排放管上拧得太高，如遇此情况，当阀门组装后，在阀瓣与其座相接触前，阀瓣座将加载荷于调节环的边上，为了避免此情况的发生，应使调节环上的孔正好低于喷射器的螺纹，通过这些孔应不能看到螺纹。
