进口保温截止阀【欧洲进口十大品牌】德国奥莱斯
进口保温截止阀【欧洲进口十大品牌】德国奥莱斯结构原理：
是在阀体焊装一层金属夹套，通过对金属夹套内注入蒸汽、导热油、冷却水、冷气等，使阀体的介质在常温、升温、降温等条件下，达到所需要的温度，起到保温或保冷的作用。保温阀门是用在常温下会凝固的高粘度、蒸汽或其它保温、保冷介质，确保阀内介质能够正常工作。
保温阀门具有良好的保温保冷特性，且阀门的通径与管径一致，同时又能有效降低管路中介质热量损失。具有良好的保温保冷特性，同时又能有效降低管路中介质热量损失。保温阀门在石油、化工、冶金、制药等各类系统中得到较多应用，有效降低管路中介质热量的损失，防止介质结晶、凝固等相象的出现。保温阀门的作用是在温度高或低的情况下通过阀门时，保温阀门内的物质对介质产生保温效果，使介质不会凝结或粘在阀体内部，让阀门的启闭能正常运作。
It is to weld a layer of metal jacket on the valve body. By injecting steam, heat conducting oil, cooling water and air into the metal jacket, the medium of the valve body can reach the required temperature under the conditions of normal temperature, heating and cooling, thus playing the role of heat preservation or cold preservation. Insulation valve is a high viscosity, steam or other insulation and cooling medium which solidifies at room temperature to ensure the normal operation of the medium inside the valve.
The insulation valve has good insulation and cooling characteristics, and the diameter of the valve is the same as the diameter of the pipe. At the same time, it can effectively reduce the loss of medium heat in the pipeline. It has good heat preservation and cooling characteristics, and can effectively reduce the heat loss of medium in the pipeline. Thermal insulation valves are widely used in petroleum, chemical, metallurgical, pharmaceutical and other systems, which can effectively reduce the loss of medium heat in pipelines and prevent the appearance of medium crystallization and solidification. The function of heat preservation valve is to pass through the valve at high or low temperature. The material in the heat preservation valve produces heat preservation effect on the medium, so that the medium will not condense or stick to the inside of the valve body, so that the valve can operate normally.
进口保温截止阀【欧洲进口十大品牌】德国奥莱斯工作原理
1）截止阀只许介质单向流动，安装时有方向性。截止阀的结构长度大于闸阀，同时流体阻力大，长期运行时，密封可靠性不强。
直通式截止阀
2）直流式截止阀：在直流式或Y形截止阀中，阀体的流道与主流道成一斜线，这样流动状态的破坏程度比常规截止阀要小，因而通过阀门的压力损失也相应的小了。
3）角式截止阀：在角式截止阀中，流体只需改变一次方向，以致于通过此阀门的压力降比常规结构的截止阀小。
4）柱塞式截止阀：这种形式的截止阀是常规截止阀的变型。在该阀门中，阀瓣和阀座通常是基于柱塞原理设计的。阀瓣磨光成柱塞与阀杆相连接，密封是由套在柱塞上的两个弹性密封圈实现的。两个弹性密封圈用一个套环隔开，并通过由阀盖螺母施加在阀盖上的载荷把柱塞周围的密封圈压牢。弹性密封圈能够更换，可以采用各种各样的材料制成，该阀门主要用于“开”或者“关”，但是备有特制形式的柱塞或特殊的套环，也可以用于调节流量。
