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.

電動內(nèi)螺紋三通球閥安裝注意事項

(1)取掉法蘭端兩邊的保護蓋，在閥*打開的狀態(tài)下進行沖洗清潔。
(2)安裝前應(yīng)按規(guī)定的信號(電動或氣動)進行整機測試(防止因運輸產(chǎn)生振動影響使用性能)，合格后方可上線安裝(接線按電動執(zhí)行機構(gòu)線路圖)。
(3)準(zhǔn)備與管道連接前，須沖洗和清除干凈管道中殘存的雜質(zhì)(這些物質(zhì)可能會損壞閥座和球)。
(4)在安裝期間，請不要用閥的執(zhí)行機構(gòu)部分作為起重的吊裝點，以避免損壞執(zhí)行機構(gòu)及附件。
(5)本類閥應(yīng)安裝在管道的水平方向或垂直方向。
(6)安裝點附近的管道不可有低垂或者承受外力的現(xiàn)象，可以用管道支架或者支撐物來消除管線的偏離。
(7)與管道連接后，請用規(guī)定的扭矩交叉鎖緊法蘭連接螺栓。

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.

電動內(nèi)螺紋三通球閥的密封材料
球閥的密封性能在很大程度上取決于密封件的材料，正確合理的選擇密封材料對保證球閥工作性能，延長使用壽命具有重要意義。對材料的要求有具有高的耐磨損耐溶解性能力，應(yīng)該具有足夠高的強度，能長期經(jīng)受流體壓力作用，并能多次拆裝，彈性和塑性好，滑動摩擦系數(shù)和膨脹系數(shù)低，耐磨性能和自潤滑性能優(yōu)良，并具有好的不滲透性和不吸濕性等，能夠耐寒耐熱和耐溫度的急劇變化，并有良好的導(dǎo)熱性能。密封材料有非金屬和金屬密封材料兩種。
1．非金屬密封材料：常用的有纖維材料，橡膠，工程塑料以及碳素材料等。這些材料具有低的彈性模數(shù)和高的泊桑系數(shù)，因此，在較低的密封力作用下，即能獲得大的彈塑性變形，對可能產(chǎn)生滲透的間隙有較好的填塞作用。
2．金屬密封材料：常用的有鋁，銅及硬質(zhì)合金，鋁銅常用于制造球閥用法蘭墊片，硬質(zhì)合金則用于高溫球閥閥座和球體的密封面。

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.
