2.两阀座密封三通球阀具有结构紧凑、外形美观、密封性能好,它能实现对管道中介质流向的切换。也能使相互垂直的两个通道连通或关闭。
3.四阀座密封三通球阀具有造型美观、结构紧凑合理,它不仅可实现介质流向的切换,也可使三个通道相互连通,同时可关闭任意一个通道,使另外两个通道连通,灵活控制管路是介质的合流或分流。
4.T型阀芯孔道可使三条正交的管道互相连通或切换,起分流或合流作用;L型孔道连接相互正交的两管道。使另一条孔道切断,起改变介质流向作用。
5.三通球阀的主要产品系列:如流向图所示选择工况。
Product features of internal thread electric three-way ball valve
1. The three-way ball valve has two-seat and four-seat sealing structures. The spool has two structural forms, L-type and T-type. The rotation angle of the spool is controlled, and the connection state of the spool and the pipe port can be changed. The three branch pipes can be different Combination control. The three-way ball valve has a large flow capacity and can control gas, steam, and liquid. It is more suitable for controlling high-viscosity, fibrous and granular fluids. It is also suitable for occasions with strict sealing requirements.
2. The two-seat sealed three-way ball valve has a compact structure, beautiful appearance, and good sealing performance. It can switch the flow direction of the medium in the pipeline. It can also connect or close the two channels perpendicular to each other.
3. The four-seat sealed three-way ball valve has beautiful appearance, compact and reasonable structure. It can not only switch the flow direction of the medium, but also make the three channels communicate with each other. At the same time, it can close any one of the channels to connect the other two channels and control the tube flexibly. Path is the confluence or divergence of media.
4. T-shaped spool orifice allows three orthogonal pipelines to communicate or switch to each other to split or merge; L-shaped orifice connects two orthogonal pipelines. Cut off the other channel to change the flow direction of the medium.
5. The main product series of the three-way ball valve: select the working condition as shown in the flow diagram.
电动内螺纹三通球阀安装注意事项
(1)取掉法兰端两边的保护盖,在阀*打开的状态下进行冲洗清洁。
(2)安装前应按规定的信号(电动或气动)进行整机测试(防止因运输产生振动影响使用性能),合格后方可上线安装(接线按电动执行机构线路图)。
(3)准备与管道连接前,须冲洗和清除干净管道中残存的杂质(这些物质可能会损坏阀座和球)。
(4)在安装期间,请不要用阀的执行机构部分作为起重的吊装点,以避免损坏执行机构及附件。
(5)本类阀应安装在管道的水平方向或垂直方向。
(6)安装点附近的管道不可有低垂或者承受外力的现象,可以用管道支架或者支撑物来消除管线的偏离。
(7)与管道连接后,请用规定的扭矩交叉锁紧法兰连接螺栓。
Installation precautions for electric internal thread three-way ball valve
(1) Remove the protective covers on both sides of the flange, and rinse and clean with the valve fully opened.
(2) Before installation, the whole machine should be tested according to the specified signal (electric or pneumatic) (to prevent the vibration caused by transportation from affecting the performance), and then it can be installed online (wiring according to the wiring diagram of the electric actuator).
(3) Before preparing to connect with the pipeline, flush and remove the remaining impurities in the pipeline (these substances may damage the valve seat and ball).
(4) During installation, please do not use the actuator part of the valve as a lifting point to avoid damage to the actuator and accessories.
(5) This type of valve should be installed in the horizontal or vertical direction of the pipeline.
(6) The pipeline near the installation point must not sag or bear external forces. Pipe supports or supports can be used to eliminate the deviation of the pipeline.
(7) After connecting with the pipeline, please cross-tighten the flange connecting bolts with the specified torque.
电动内螺纹三通球阀的密封材料
球阀的密封性能在很大程度上取决于密封件的材料,正确合理的选择密封材料对保证球阀工作性能,延长使用寿命具有重要意义。对材料的要求有具有高的耐磨损耐溶解性能力,应该具有足够高的强度,能长期经受流体压力作用,并能多次拆装,弹性和塑性好,滑动摩擦系数和膨胀系数低,耐磨性能和自润滑性能优良,并具有好的不渗透性和不吸湿性等,能够耐寒耐热和耐温度的急剧变化,并有良好的导热性能。密封材料有非金属和金属密封材料两种。
1.非金属密封材料:常用的有纤维材料,橡胶,工程塑料以及碳素材料等。这些材料具有低的弹性模数和高的泊桑系数,因此,在较低的密封力作用下,即能获得大的弹塑性变形,对可能产生渗透的间隙有较好的填塞作用。
2.金属密封材料:常用的有铝,铜及硬质合金,铝铜常用于制造球阀用法兰垫片,硬质合金则用于高温球阀阀座和球体的密封面。
Sealing material of electric internal thread three-way ball valve
The sealing performance of the ball valve depends to a large extent on the material of the seal. The correct and reasonable selection of the sealing material is of great significance to ensure the working performance of the ball valve and prolong the service life. The material is required to have high abrasion resistance and solubility resistance, should have high enough strength, can withstand the action of fluid pressure for a long time, and can be disassembled many times, with good elasticity and plasticity, and low sliding friction coefficient and expansion coefficient. Excellent wear resistance and self-lubricating properties, good impermeability and non-hygroscopicity, etc., can withstand cold, heat, and rapid changes in temperature, and have good thermal conductivity. There are two types of sealing materials: non-metallic and metallic sealing materials.
1. Non-metallic sealing materials: fiber materials, rubber, engineering plastics and carbon materials are commonly used. These materials have low elastic modulus and high Poisson coefficient. Therefore, under the action of low sealing force, large elastoplastic deformation can be obtained, and the gap that may be penetrated has a better filling effect.
2. Metal sealing materials: commonly used are aluminum, copper and cemented carbide. Aluminum and copper are often used to make flange gaskets for ball valves, and cemented carbide is used for high-temperature ball valve seats and the sealing surfaces of spheres.
