With one valve, three functions can be successfully completed: water hammer check valve, gate valve, and balance valve.<br>2. When the pump stops running, the spring force closes the valve disc first, thus preventing water hammer.<br>3. By adjusting the opening, the output of the pump can be adjusted.<br>4. Equipped with an indicator, the opening degree of the valve can be confirmed with the eyes.<br>5. The sealing gasket is made of nitrile rubber, so it will not leak at all and can absorb impact.<br>6. The spring is made of stainless steel and therefore has strong corrosion resistance.<br>7. Equipment materials and costs that can save water and reduce installation space.<br>8. Due to its streamlined shape and structure, the pressure drop is very small.<br>9. Due to its role as a bypass, it has the function of recovering water from the outlet side pipeline and supplementing water intake when a vacuum occurs on the inlet side.<br>10. Both horizontal and vertical pipelines can be installed.<br><br>Structure and working principle:<br>The three in one check valve is installed on the pump outlet of the water supply and drainage, cold and warm water treatment, boiler condensate, and secondary water supply pipelines in general buildings, apartments, and factories to prevent medium backflow in the pipeline caused by pump

<BR><BR>HD7B41X液控止回阀适用于介质为水的泵出口管路上，作为闭路并和止回阀，用来避免和减少管路系统中介质的倒流及产生过大的水锤，以保护管路系统。本阀靠液压驱动开启，靠重锤势能关闭，启闭灵活可靠。该阀安装载泵后，可代替闸阀、蝶阀和止回阀两台阀门。且流阻系数仅为上述两台阀木讷流阻系数的30%。因此，该类阀门为节能产品。关闭时，液控装置分快关、慢关两个阶段：前60°为快关，后30°为慢关，根据工况不同，可调节快慢关时间和快、慢关切换角度，以防止发生较大水锤。该阀门还具有保压功能：本蝶阀的液压系统重设有蓄能器，蓄有压力油，补充系统的泄漏，并可自动补压。同时具有自动复位功能，当阀门开度降低（重锤下落）15°时，油泵启动，自动复位。备用复位装置，本蝶阀开启后，当液压系统中出现微量的内漏蓄能器补充，压力降至一定值时，继电器发令补压，微防止压力继电器失灵，设有行程开关复位装置，即在本阀开启位置有保压和保位双位保护功能

http://www.91way.com/info_en/5391.html 止回阀 2026-2-2 19:27:17 H41H止回阀是一种阀瓣沿着阀体垂直中心线滑动的止回阀，H41H止回阀只能安装在水平管道上，高压小口径的止回阀阀瓣可采用圆球形，H41H止回阀的阀体形状与截止阀一样（可与截止阀通用），因此它的流体阻力系数较大，但密封性较旋启式好。 <BR><BR>H41H升降式止回阀安装尺寸

<BR>　　本蝶阀适用于介质为水的泵出口管路上，用来避免和减少管路系统中介质繁荣倒流及产生过大的水锤，以保护管路系统，其功能事以一阀代两阀（传统的管路设计中以闸阀配止回阀或以普通蝶阀配止回阀） <BR><BR>三、特点 <BR>1、HD7Q41X型全液控止回蝶阀控制部分采用了全液控形式，以蓄能器取化了重锤部分，减小了能量损耗，传动机构得到简化，占具空间笑，与 　一般型蝶阀相近。安装方便　，即课左、右卧式安装，也可以立式安装。 <BR>2、该阀装在泵后，可代替闸阀（蝶阀）和止回阀两台阀门。且流阻系数小，大口径蝶阀流阻系数只比闸阀略高。因此，该类阀门为节能产品。 <BR>3、HD7Q41X型阀关闭时，可以根据管道系统的特性或用户要求调整快、慢关段的时间和切换角度，从而达到消除或减小水锤，保护系统作用。 <BR>4、如所有行程开关都采用电感式接近开关，移除液压站，防护等级可达IP67。 <BR><BR>四、主要技术参数 <BR><BR> <TABLE style="WIDTH: 99%; BORDER-COLLAPSE: collapse" border=1 cellSpacing=1 cellPadding=0 width="99%" align=center> <TBODY> <TR> <TD

打开出口阀，给水泵启动，给水达到一定的压力后，阀芯自动升起，推离阀座，给水即流出。同时阀芯连杆拔动排空口阀片封闭排空口。当给水泵流量减小时，阀芯下落，推动连杆拔开排空阀片，开启再循环门维持水泵最小流量。当停泵时，阀芯自动下落关闭通道，从而防止高压水锤对给水系统的破坏。 <BR><BR>175H48Y(H)-200空排止回阀主要参数 ：<BR><BR> <TABLE style="WIDTH:

http://www.91way.com/info_en/9856.html 止回阀 2025-12-27 14:27:34 概述: <BR>H42型升降止回阀具有结构新颖、体积小、重量轻、流体阻力小、密封可靠、启闭平稳、耐磨损、使用寿命长，油压、缓闭不受介质影响，有较好节能效果等特点，可安装于水泵出口处，能避免产生水锤、水击声和破坏性冲击，达到防止逆流和保护设备的目的，有较好节能效果。广泛用于给排水、消防、建筑、暖通、工业系统。 <BR><BR>H42型升降止回阀正常处于关闭状态，由于管线中进口端介质的压力作用，而克服弹簧阻力使阀门开启。当进口端介质压力低于出口端时，弹簧将阀芯推向阀座而使阀门关闭，阻止介质逆流，故起止回作用。&nbsp; <BR><BR>H42型升降止回阀由于采用弹簧支撑阀芯，故采用立式安装或卧式装均可。&nbsp; <BR><BR>性能规范： <BR><BR> <TABLE style="WIDTH:

<BR>2。公称压力：类150至600; <BR>3。标称尺寸：2“至24”; <BR>4。适用温度。：-40至350摄氏度 <BR>连接形式：法兰，。 <BR><BR>工作原理 <BR>H44TC旋启式陶瓷止回阀是防止介质倒流的自动阀门，流体从进口侧流向出口侧。止回阀的阀瓣在流体压力的作用下开启，介质倒流是靠阀瓣的自重或辅助机构自动关闭，以防止介质倒流保护设备的政策运行。该产品的阀瓣、阀座密封面的材料均采用结构陶瓷制造，提高了阀门的耐磨性与耐冲刷性，大大的延长了使用寿命。该产品在阀座上没有防止冲击的结构，以保护阀座抗冲击性。 <BR><BR>H44TC旋启式陶瓷止回阀使用于电厂干灰系统仓泵的进出料门，也可用于矿山、化工等各类有磨损的干灰、水渣等介质管道的止回装置。公称压力有1.0MPa和1.6MPa，适应温度≤200℃。 <BR><BR>H44TC旋启式陶瓷止回阀闭后任何方向全部密封。阀体阀盖采用WCB铸钢件或不锈钢铸件。密封面采用硬密封件。本阀料口全流通无阻挡物，耐磨性能抢，密封性能好，启动负荷小卡灰及结灰现象少。 <BR><BR>本阀采用高档曾韧陶瓷密封，机械强度高耐磨性能好使用寿命长。结构紧凑可任意角度安装。<BR> http://www.91way.com/info_en/13739.html 止回阀 2025-12-23 17:47:56 <P align=center><A

H42W止回阀正常处于关闭状态，由于管线中进口端介质的压力作用，而克服弹簧阻力使阀门开启。当进口端介质压力低于出口端时，弹簧将阀芯推向阀座而使阀门关闭，阻止介质逆流，故起止回作用。H42W止回阀由于采用弹簧支撑阀芯，故采用立式安装或卧式装均可。 <BR><BR>H42W立式止回阀主要性能规范 ： <BR><BR> <TABLE style="WIDTH: 100%;
